10.3 Selection of connections

In the designed gear box, key connections are used to connect the shafts to the torque transmitting parts.

We use prismatic keys with rounded ends as per GOST 2336078. The length of the key is assumed to be 5... 10 mm less than the length of the hub of the part to be fitted. Landing for helical wheel H7/r6.

Design of bearing assemblies

The designed gearbox uses grease of bearing units. To isolate the bearing assembly from the inner cavity of the reduction gear box, containment rings with a width of 10... 12 mm are used, and insulation of the output sections of the shafts from the environment is achieved using cuff seals according to GOST 875279. Inner ring of bearing rests against oil-retaining ring, and outer ring is fixed by spacer bushing between bearing and cut-in bearing cover.
