Geared Systems
Model Number: TM1018
A dynamic test system for evaluating the performance and efficiency of geared, belt, and chain drives.
Overview
An experimental unit to allow students to find the dynamic efficiency of various drive types. The unit comes complete with a gear drive unit which can be configured as a simple or compound drive.
A bench-mounting base unit forms the main part of this set of products. Supplied with a three-shaft gear drive unit as standard, the base unit dynamically tests the gear drive and the other optional drive units (TM1018b Toothed Belt Drive, TM1018c Round Belt Drive, TM1018d Roller Chain Gear Drive and TM1018e Helical Gear Drive). The dynamic tests run the input of the different drive units at a given speed using a motor, while measuring the input power. At the same time, a dynamometer loads the output of the drive unit while measuring the output power. Students use the measurements to find the performance and efficiency of the drive unit.
Students may set the gear unit (supplied) as a simple or compound drive by sliding a gear in or out of mesh on the third shaft.
