Parellel Shaft Geared Motors
Parallel shaft geared motors are the modern version of coaxial geared motors. As a result of their compact and short design, they take up less space than helical geared motors. Parallel shaft geared motors can either have a solid shaft – or alternatively a hollow shaft as so-called plug-on gear unit. This means that the geared motor is optimally integrated into the driven machine. Additional components – e.g. such as gear wheels or chain wheels – to transmit the force to the driven machine are eliminated. Parallel shaft geared motors represent the space and weight-saving solution within the range of coaxial geared motors.
MOTOX parallel shaft geared motors can be supplied for the power range up to 200 kW and rated gear unit torques up to 20,000 Nm.
- Geared motors are available in the following versions:
- Foot or flange-mounting versions
- Version with torque bracket
- Solid or hollow shaft
- Hollow shaft with key connection, shrunk-on disk, splines

Further, double geared motors with 4, 5 and 6 stages are available with gear ratios of i = 299…71,388.
Parallel shaft geared motors are, for instance, used in agitators.
