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

Sizes from JPL 1520 version H to JPL 6020:<br />
These gearboxes are provided with two spigot diameters. It is suffi cient to create a single spigot on the structure<br />
when the radial loads on the output shaft are not present or when they are less than 50% of the maximum load<br />
permitted.<br />

Size JPL 11000 and greater: the spigots will have an F8 tolerance.<br />
Gearboxes with female splined shaft:<br />
The female version gearboxes are not suitable for supporting output radial loads; it is therefore extremely<br />
important to properly align between the gearbox and the driven shaft. It is also necessary to check that the driven<br />
shaft does not undergo bending during the work phases.<br />
Foot mounted:<br />
The support surfaces must be level, and in axis with the machine being driven, to obtain this it is extremely<br />
important that the levelling and alignment operation is carried out carefully. An improper setting of the support<br />
base or an incorrect alignment can adversely affect the life of the gearbox.<br />
Shaft mounted gearbox with shrink disc:<br />
It is necessary to carry out an anchorage of the torque arm that is not constrained to the axis of the gearbox. The<br />
anchorage must also be suitable shock proof. In the dimensional tables of each gearbox one can fi nd the minimum<br />
torque arm lengths needed to carry out the application correctly.<br />
