Mounting the gear unit on the machine
This chapter contains information on how to mount the gear unit on the machine.
5.4.1
Mounting PK, PKX, PHK, PHKX, PHQK gear units on the machine
Prerequisites
§
The connecting structure for the drive in the machine is designed according to the weight and torque and takes into
account forces that act on the drive.
§
The connecting structure is flat, vibration-reducing and torsion-resistant.
The perpendicularity deviation of the flange contact surface of the connecting structure to the gear unit shaft axis does
not exceed 0.03 mm per 100 mm.
§
The gear unit housing is grounded via the connecting structure or attached motor.
§
The centering diameter of the connecting structure has the tolerance of ISO H7.
§
Sufficient ventilation for the mounted drive is ensured.
Procedure
1.
Remove the corrosion protection from the contact surfaces of the output flange and connecting structure.
2.
Position the gear unit in the mounting position specified in the order.
3.
Center the gear unit in the connecting structure using the pilot/pilots of the gear unit housing.
4.
Mount the output flange of the gear unit to the connecting structure using screws. Details on the screws can be found
in the following table.
5.
Tighten the screws evenly in multiple passes with increasing torque and alternating diagonally. The tightening torques
can be found in the chapter
