single-stage, two-stage or three-stage spur gear with distributed rotational inertia

Description:

• Gears are employed as a link between driving machine and driven 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.
• The GL 210unit is used to study the dynamic behaviour in single-stage, two-stage and three-stage spur gears during transient operation.
• The trainer includes four parallel shafts, three drive wheels and three drive gears.
• Coupling pins can be used to couple the shafts such that different gear stages can be realised.
• A flywheel may be attached to each shaft in order to increase the rotational inertia.
• The gear is accelerated via a cable drum and a variable set of weights.
• The set of weights is raised via a crank.
• A ratchet prevents the weight from accidentally escaping.
• A clamping roller freewheel enables free further rotation after the weight has been released.
• A hand brake allows smooth deceleration.
• The transparent protective cover with safety lock prevents accidental contact with the rotating parts.
• Inductive speed sensors on all drive gears allow the speeds to be measured.
• The measured values are transmitted directly to a PC via USB.
• The data acquisition software is included.
• The angular acceleration can be read from the diagrams.
