3.8 Functional description
The TW 160 machine consists of a worm gear (gear drive) with flange-connected
motor.
Power transmission takes place on motors of the IMB9 model series (flanged-on
design with 1 bearing) via a rigid connection between the motor and worm shaft via
worm wheel, traction sheave shaft to the traction sheave.
In the case of motors of the IMB5 model series (flanged-on design with 2 bearings), a
flexible coupling (SA14) is required between the motor and gear drive.
Brake
The dual-circuit outside shoe brake is spring actuated. Two independently acting
brake shoe press the brake lining with preset spring force onto the brake disc.
The braking force is configured in such a way that one of the brake shoes is sufficient
to bring an elevator car loaded with full weight to a standstill.
The brake is released by electrically operated magnetic clamps with armature base
plate.
For manual operation, a brake release lever is fitted.
Gear housing
The TW160 has a monobloc housing with two fitted and screw-connected bearing
brackets. The motor flange is cast onto the housing.
The right-hand or left-hand version of the traction sheave is created with the
corresponding installation of the bearing brackets in the housing.
The gear housing is cast from EN-GJL 250.
