EXPERIMENTAL STUDYING REDUCING THE VIBRATION OF A TRI-RING REDUCER

A triring reducer is a type of epicyclic gear drive with small tooth number difference and internal tooth. Adopting the new conception of parallel and movable axis of multiple mechanisms, this kind of gear drive has many characteristics such as simplicity and compactness in structure, large transmission ratio, high efficiency and ability to transmit power by input through single or multiple axes, etc. In this paper, the transmission principle of the triring reducer was studied. Based on the result of dynamic analysis, the developed design of reducing vibration has been obtained, then the specimens of reducer are designed and manufactured in order to verify the effect of the developed design, the vibrational experiment was carried out on the gear transmission test rig. Testing result shows that the vibrating intensity descends obviously by increasing the operating angle and the stiffness of system, however the result is not good by modification of the internal teeth.
