7. Mounting instruction 7.1. Installation Gearbox with fl ange and male shaft:: The connecting surface should be fl at unpainted, machine tooled and at 90 degrees to the rotation axis. The following table shows the required spigots with their representative tolerances. Sizes up to JPL 6510: the spigots will have an H8 tolerance.

It is suffi cient to create a single spigot on the structure when the radial loads on the output shaft are not present or when they are less than 50% of the maximum load permitted. 0 +0,089 Size JPL 11000 and greater: the spigots will have an F8 tolerance. Gearboxes with female splined shaft: The female version gearboxes are not suitable for supporting output radial loads; it is therefore extremely important to properly align between the gearbox and the driven shaft. It is also necessary to check that the driven shaft does not undergo bending during the work phases. Foot mounted: The support surfaces must be level, and in axis with the machine being driven, to obtain this it is extremely important that the levelling and alignment operation is carried out carefully. An improper setting of the support base or an incorrect alignment can adversely affect the life of the gearbox. Shaft mounted gearbox with shrink disc: It is necessary to carry out an anchorage of the torque arm that is not constrained to the axis of the gearbox. The anchorage must also be suitable shock proof. In the dimensional tables of each gearbox one can fi nd the minimum torque arm lengths needed to carry out the application correctly. 0 +0,097 +0,086 +0,226 www.jahns-hydraulik.de
7.2 Lubrication The gearboxes are supplied without oil. Before use, the gearbox must be fi lled with oil up to the level indicated using one of the lubricating oils advised. The choice and the quantity of oil will be referred to the installer/user based upon the type of application. 7.3 Paint The supplied gearboxes are not painted. A few parts are treated with a base layer of water soluble epoxy ester red oxide. It is the responsibility of the customer to carry out the surface treatment using a paint that is compatible with the base layer. O-rings must be protected during the painting. 7.4 Installation of fl ange motors The installation of the motors to the coupling fl ange supplied by Jahns is a particularly simple operation, but it must be carried out following the following important suggestions: -Lubricate the coupling with a light fi lm of grease or anti-seizure lubricant; -Ensure that the motor rests freely on the gearbox fi xing fl ange without forcing on either the shaft or the spigot; -Tighten screws. For further information refer to the maintenance and operation manual. 7.5 Installation of motors with connection couplings When a connection coupling between motor and gearbox is used, one must verify that the alignment between the motor and the gearbox is compatible with the type of coupling. Couplings are widely used in industrial applications for the various functions that they can perform such as: - limit the input torque, - dampen vibrations coming from the motor, - compensate small misalignments. For the application of couplings, reference must be made to the component’s supplier operating manual. 7.6 Weights For the gearboxes aproximative weights see page G.241. 8. Storage The gearboxes must not be stored in the open or in direct contact with the ground. For long time periods they just be stored full of oil, with the external worked parts covered with grease and the coupling surfaces protected with anti-oxidant agents and operated under vacuum (a complete rotation of the output shaft is suffi cient) at least once every two months. For further information regarding storage, please refer to the maintenance and operating manual. www.jahns-hydraulik.de Page B. 15 H Y D R A U L I K
