Fault analysis and structure improvement of multi stage driving machine of performance stage wagons

Abstract

Abstract: Stage wagon driver is the core component to realize the accurate and stable operation, prolong the service life and reliable start and stop of performance platform. In view of the vibration and noise of the traditional rack and pinion stage wagon when it is driven from the first stage to the second stage, the structure of the driving machine is improved and designed through fault analysis. The specific work includes: rounding the end of the rack to gradually mesh, adding spring device to reduce the impact, using frequency conversion speed control system to ensure the synchronous operation of the multi-stage drive machine, and using elastic sleeve pin coupling to drive the gear to drive the rack. Based on joint simulation of Solidworks and Adams, the instantaneous contact stress of gear rack meshing of the improved driving machine is analyzed. Compared with the traditional driving mechanism, the improved driving mechanism designed by the method proposed in this paper makes the stage wagon run well, and its vibration and noise are reduced compared with the traditional rack and pinion drive stage wagon.
