Custom versions are available on request.
- 3 sizes with various gear ratios
- output torque from 1 to 5Nm
- easy to install
- low backlash versions available
- low noise
- custom versions
Gearbox assembly
The GSR worm gearboxes leave the factory individually tested, filled with the right amount of lubricant, and prepared for mounting on the motor specified in the order. They can be put into operation immediately after being mounted.
The standard mounting position is horizontal. In the case of vertical mounting, steps may have to be taken to make sure the upper parts of the gearbox receive proper lubrication. In this case, please enquire. The centring and attachment surfaces must be free of grease, undamaged, and positioned precisely in relation to the shafts of the overall system. Any offset between housing and shaft would apply excessive loading at gears and bearings. Shocks or blows should be avoided when mounting couplings etc., on the gearbox shaft, because they could result in bearing damage.
Motor mounting in three simple steps:
- fasten motor pinion
- screw mounting plate in place
- put on gear unit and screw it together
Mounting instructions are provided with every gearbox. The concentricity and run-out tolerances of the motors are defined by DIN 42955-R.
