Dynamic Behaviour of Multistage Spur Gears Model MT 024

Gears are employed as a link between drive machine and work machine. They are used to vary torque and
speed and to change direction. The aim of dynamic gear analysis is an understanding of the motion sequences
and the influence of inertia.
Sci-tech Dynamic Behaviour of Multistage Spur Gears Model TM 024 unit is used to study the dynamic behaviour in single-stage, two-stage and three-stage spur gears during transient operation.

Item Description

* Single-stage, two-stage or three-stage spur gear with distributed rotational inertia1
* Drive via cable drum and variable set of weights1
* Inductive speed sensors on all shafts1
* Software for data acquisition

Technical Specifications

[1] investigation of the dynamic behaviour of 1-stage, 2-stage or 3-stage spur gears
[2] 4 shafts, 3 drive wheels and 3 drivegears
[3] shafts can be coupled by coupling pins
[4] optional attachable flywheels to increase the rotational inertia on each shaft
[5] gear is accelerated via cable drum and variable set of weights
[6] weight raised by hand crank; ratchet prevents accidental release
[7] clamping roller freewheel enables free further rotation after the weight has been released
[8] gear decelerated via hand-operated brake
[9] transparent protective cover with safety lock and protective grill for the set of weights
[10] inductive speed sensors on all drive-gears
[11] Software for data capture via USB under Windows Vista or Windows 7
