FAST, ACCURATE TENSION READINGS<br />

<strong>Belt</strong> Tension Testers<br />

Testing tension with a spring tester requires muscle, a piece of string<br />

and at least three hands! The Sonic Tension Meter works on the theory<br />

that belts, like strings, vibrate at a particular natural frequency based<br />

on mass and span length. The meter converts this frequency into a<br />

measurement of tension.<br />

To test tension:<br />

1. Enter belt mass constant, belt width & span length into meter.<br />

2. Hold meter to belt span, then strum belt to make it vibrate. The<br />

meter will measure the vibration and convert into belt tension.<br />

Features:<br />

• Output reading measurable in hertz, pounds,<br />

kilograms and newtons.<br />

• Frequency range from 10-5000 hertz.<br />

• Variable frequency range filters.<br />

• Auto gain control automatically adjusts meter<br />

sensitivity.<br />

• 20 memory registers for belt constants.<br />

Model<br />

Flexible Sensor: can be bent and repositioned for one-hand options<br />

Replacement Cord Sensor<br />

Inductive Sensor: use in high-noise or windy environments<br />

Replacement A/C Adapter: only available for former Model 305FD<br />

Pencil Type Tension Gauge: 30 lbs. Max. deflection force<br />

Information<br />

IDLER USAGE<br />

Idlers in synchronous belt drives are commonly used to take up belt slack, apply installation tension or to clear obstructions within a system. While idlers cause additional<br />

belt bending, resulting in fatigue, this effect is generally not significant as long as proper design procedures are followed. Synchronous belts elongate very little over time,<br />

making them relatively maintenance free. All idlers should be capable of being locked down after being adjusted and should require little additional attention. Specific<br />

guidelines and recommendations are given below.<br />

Inside/Outside<br />

Inside idlers are generally preferred over backside idlers from a belt fatigue standpoint. Both are commonly used with good success. Inside idlers should be pulleys, but<br />

can be flat, if the O.D. is equivalent to the pitch diameter of a 40-groove pulley. Backside idlers should be flat and uncrowned.<br />

Tight Side/Slack Side<br />

Idlers should be placed on the slack (or nonload-carrying) side, if possible. Their effect on belt fatigue is less on the slack side than on the tight (or load-carrying) side. If<br />

spring-loaded idlers are used, they should never be placed on the tight side (see Spring-Loaded Idlers). Also, note that drive direction reversals cause the tight and slack<br />

spans to reverse, potentially placing the idler on the tight side.<br />

Idler Placement<br />

In synchronous belt drives, idlers can be placed nearly anywhere they are needed. Synchronous drives are much less sensitive to idler placement and belt wrap angles<br />

than V-belt drives. The designer should make sure that at least 6 belt teeth are in mesh on load-carrying pulleys. For every tooth in mesh less than this (with a minimum<br />

of 2), 20% of the belt torque rating must be subtracted. In order to minimize the potential for belt ratcheting, each loaded pulley in the system should also have a wrap<br />

angle of at least 60°. If a loaded pulley has less than 6 teeth in mesh and 60° of wrap, idlers can often be used to improve this condition. Nonloaded idler pulleys do not<br />

have tooth meshing or wrap angle restriction.<br />

Spring-Loaded Idlers<br />

Using a spring to apply a predetermined force against a tensioning idler to obtain proper belt installation tension is acceptable as long as the idler can be locked down<br />

after belt installation.<br />

Dynamic spring-loaded idlers are generally not recommended for synchronous belt drives. If used, spring-loaded belt idlers should never be used on the tight (or loadcarrying)<br />

side. Tight side tensions vary with the magnitude and type of load carried by the system. High tight side tensions can overcome the idler spring force allowing<br />

the belt to ratchet. In order to prevent this from occurring, an excessively high spring force is required. This high spring force can result in high shaft/bearing loads and<br />

accelerated belt wear.<br />

If dynamic spring-loaded idlers are to be used, they should be used on the slack (or nonload-carrying) side of the drive. Potential drive loading variations in the system<br />

will have the least possible impact on idler movement due to spring compression with the idler placed in this way. Be sure to note that the tight and slack spans shift as<br />

the direction of drive rotation reverses. This could place the spring-loaded idler on the tight side. In some cases, drive vibration and harmonic problems may also be<br />

encountered with the use of spring-loaded idlers.<br />

Size Recommendations<br />

Inside idler pulleys can be used in the minimum recommended size for each particular belt pitch. Inside flat idlers can be used on the tooth side of synchronous belts as<br />

long as they are of a diameter equivalent to the pitch diameter of a 40-groove pulley in the same pitch. Drives with inside flat idlers should be tested, as noise and belt wear<br />

may occur. Flat backside idlers should be used with diameters at least 30% larger than the minimum recommended inside pulley size.<br />

Quality Transmission Components is the exclusive distributor of Zetasassi <strong>Belt</strong> and Chain Tensioners in the US,<br />

Canada and Mexico. These well-made tensioners will improve the operation of belt and chain drives by many hours<br />

by keeping the tension constant. This occurs because the tensioners create:<br />

1) Automatic reduction in the belt or chain slack.<br />

2) Reduction of noise and vibration.<br />

3) Uniform and more efficient transmission of drive torque.<br />

4) Decrease in sprocket, pulley, belt or chain wear.<br />

5) Increased life of belts and chains.<br />

6) Possibility to adjust the tension of the drive.<br />

These units are easy to install and maintenance-free. The spring-loaded units, available in rotational and linear<br />

movement types, will automatically keep the tension constant, eliminating frequent manual adjustments which<br />

would interrupt the operation of the machinery.<br />

All tensioners should be installed on the slack side of belts and chains. For rotational movement units, please make<br />

sure to install the units, as shown in fig. 1.<br />

It is also recommended, for both rotational and linear tensioners, that the tension force be applied from the outside<br />

of the belt or chain loop as to not reduce the wrap-around angles of the belt or chain over the pulleys or sprockets.<br />

As shown in the pictorial index on page 6, several designs of tensioners are offered as arm only, arm with roller<br />

attached for belts, arm with sprocket attached for chains, arm with polyethylene sliding head for chains, or arm with<br />

V-belt pulley attached.<br />

Further variations are offered, as well as replacement heads, as shown in the pictorial index on page 7.<br />

Most chain tensioners are also offered with ASA or ISO single, double and triple chain heads.<br />

Availability of heads other than for single chain is given on each product page.<br />

• Levers in high-tensile light alloy (except the smallest size which is plastic).<br />

• Idler rollers in zinc plated steel, aluminum or nylon.<br />

• V-belt pulleys in nylon.<br />

• Sprockets in steel or hardened steel.<br />

• <strong>Pulleys</strong>, sprockets and rollers have double-seal permanently oiled ball bearings.<br />

• Sliding head’s orientation is adjustable, and it is made of low friction, wear-resistant polyethylene<br />

(dynamic friction coefficient of 0.06 on dry steel) with maximum operating temperature of 65°C (149°F).<br />

These tensioners take up the chain or belt slack, and keep the tension constant without the operator making any<br />

adjustments over a range of approximately 45° (30° for the largest size).<br />

• Can operate at temperatures above 100°C (212°F) (except TCP series).<br />

• Uses special steel springs with an extreme high yield point and prestress, so as to maintain the<br />

pressure as constant as possible throughout the range.<br />

• Can be assembled either from inside or outside of the machine (see fig. 3 ).<br />

In a typical application, the following benefits were achieved*:<br />

• 23% increase of chain life.<br />

• 7% reduction of vibration.<br />

• 12% reduction of noise.<br />

• Reduction in chain slackening.<br />

• Elimination of the need for maintenance.<br />

ET Type ET-PU Type ETR Type<br />

ET-PUG Type<br />

The ET, ET-PU, ETR and ET-PUG consist of die-cast alloy bases and mounting heads on which rollers or sprockets are<br />

attached via spring-loaded steel sliding arms. These units are also available with an integral “End-of-stroke”<br />

sensing switch which is not retrofittable and must be ordered at the time of initial purchase. (The availability is<br />

detailed on each product page).<br />

The ET series are especially suitable for high-temperature operations over 100°C (212°F), since they are<br />

100% metal.<br />

ORIENT1 Type<br />

NT Type<br />

ORIENT1-PU Type<br />

The Orient1 series tensioners are not spring-loaded. They have the feature of being able to swivel in any direction,<br />

both before and after installation. The teeth built into the two mating parts allow the arm to be positioned every<br />

15° throughout the entire 360° revolution relative to the base. At each of these 15° positions, two of the eight<br />

holes in the arm align with the threaded holes in the base, so that the screws supplied with the unit can fasten the<br />

arm at the desired position. While these units lack the convenience of automatic tension adjustment, their simplicity<br />

and versatility in orienting and positioning offer an advantage in certain applications. Pages 3-19 thru 3-23.<br />

TO Type<br />

The TO-05 consists of a plastic base and sliding head, spring-loaded for chain drives only. It is also available with<br />

metal components such as AISI 304 stainless steel, for use in the food industry.<br />

The TO and TOT consist of die-cast alloy bases and polyethylene heads, spring-loaded for chain drives only. See each<br />

product page for head shape availability.<br />

The NT is the evolution of TO type and presents the following advantages, keeping the same operation:<br />

• Closed bottom, which minimizes dust and fluid infiltration inside the tensioner.<br />

• Plastic bushes, for a lower sliding friction, which also reduces dust and fluid infiltration.<br />

• Lower cost.<br />

make A difference<br />

you can hear<br />

Helical Gears vs Spur Gears<br />

Helical gears have slanted teeth compared to spur<br />

gears with straight cut teeth, producing a smoother<br />

gear mesh, resulting in a significant reduction in<br />

noise levels.<br />

Smooth, quiet operation<br />

Input speeds up to 6,000 rpm<br />

60db(A)<br />

Typical sound level difference between<br />

spur gearing (left) and helical cut<br />

gearing. The db(A) scale is logarlthmic.<br />

An increase of 3db doubles the<br />

apparent volume.

Selecting a Preferred Size<br />

The idea for developing metric standards worldwide comes from a preferred<br />

numbering system. Its first known application was in the 1870's by Charles<br />

Renard, a French army captain who reduced the different diameters of rope for<br />

military balloons from 425 to 17.<br />

Nominal metric sizes are identical where the metric systems have been in<br />

use for several years. These reflect preferred sizes for components such as<br />

threaded fasteners, steel plates, sheets, and bars used throughout the world.<br />

The accompanying table shows how the general system works.<br />

For example, if a designer was choosing a hydraulic cylinder, bolt, or plate<br />

thickness, the sizes in the First-choice column would be preferred. Second- and<br />

Third-choice columns are self-explanatory. The table extends to smaller and<br />

larger sizes.* For instance, 60 mm sizes would be a preferred choice as would<br />

2.5 mm devices.<br />

The three columns to the far right are the originating Renard numbers. In the<br />

First-choice column, each succeeding number is 1.6 times the previous number,<br />

with some rounding. These three columns provide the basis for the values on<br />

the left side of the table. The inch values show close corresponding English<br />

units.<br />

The form of the first table carries through to other tables in the standard.<br />

The number series shown are recommended to reduce the number of standard<br />

sizes for items such as screw threads, steel plates, steel sheets, round steel<br />

bars, lifting capacities, and hydraulic cylinder diameters.<br />
