摘要/Abstract

摘要： 驱动机是实现演艺车台精确平稳运行、延长使用寿命、可靠启停的核心部件.针对传统齿轮齿条驱动式车台由一级驱动进入二级驱动时出现的振动与噪声,经故障分析对驱动机进行结构改进设计.具体工作包括:对齿条进行端头整体倒圆以便逐渐啮合,加设弹簧装置以减少冲击,使用变频调速控制系统保证多级驱动机同步运转,并采用弹性套柱销联轴器带动齿轮驱动齿条.基于Solidworks和Adams联合仿真,对改进驱动机的齿轮齿条啮合瞬时接触力进行分析.通过振动测试和实际噪声测量,与传统驱动机构相比改进后的驱动机构使得车台运行效果良好,振动量与噪声较传统齿轮齿条驱动式车台均有所降低.

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.
