Motor Assembly SHG-2SO

Assembly of the adapter flange to the motor
For the planning of the assembly sequence it may be helpful to know the max. diameter of the Wave Generator, see illustration
56.1. In table 56.2 the diameters of the Wave Generator main axes are indicated.

Installation steps (see Illustration 57.3):
1) Mount the adapter flange (1) to the motor (2) using the screws (8).
2) Mount the Wave Generator (5) to the motor shaft.
3) Mount the adapter flange - motor subassembly to the unit (10).
Illustration 56.3
O-rings (3) and (9) or sealing agent should be used for sealing the adapter flange (1) towards the motor (2) and the unit (10).
The sealing surfaces of the o-ring or the sealing agent must not be interrupted ( e. g. by boreholes). When the unit is
lubricated with 4B No.2 or mainly operated with Wave Generator below, a motor with shaft seal should be used in order to
avoid the intrusion of the grease base oil into the motor.
