Geared Systems
Product Code : EL-TOMP-11415
Quick Answer: Geared Systems is a bench-mounting base unit for dynamic tests on drive units, with a variable-speed, low-voltage motor driving the input and a dynamometer loading the output. A gear unit is supplied and can be set as a simple or compound drive.

Key Features
- Variable-speed, low-voltage motor provides the input effort
- Dynamometer with electromagnetic braking and a hysteresis effect gives a variable load at constant torque irrespective of speed
- Motor and dynamometer on axial trunnions with race bearings, turning freely against load cell sensors to measure torque
- Flexible couplings with collets for quick, accurate alignment of the drive unit
- Sensors measure shaft speed, torque and power in and out; fans air-cool the motor and dynamometer
- Supplied gear unit set as a simple or compound drive by sliding a gear in or out of mesh on the third shaft

About This Product
Students run a drive unit at a set input speed while the dynamometer brakes the output, then use the measured input and output power to work out the performance and efficiency of the drive. Switching the gear unit between simple and compound arrangements lets them compare the two gear trains on the same base unit. Enquiries from France, Afghanistan, Mongolia, Bulgaria and Cabo Verde for the Geared Systems receive an export quotation.
