抽油机用新型圆弧齿同步带光弹性应力分析

Photoelastic Stress Analysis of a New Type Circu lar-Arc-Teeth Synchronous Belt for Pumping Units

运用光弹性理论及测试技术,对抽油机用新型圆弧齿同步带的应力分布状态进行了光弹性实验研究。与L型梯形齿同步带和HTD圆弧齿同步带的对比实验表明,新型圆弧齿同步带齿廓主要几何参数优化正确,带齿内应力分布合理,齿粮应力集中小,是较理想的抽油机用同步带。

The authors, by photoelastic technique, make an experimental investigation in the stress distribution on the new type circular-arc-teeth synchronous belt. Compared with the L type trapezoid-teeth-and the HTD circular-arc-teeth-synchronous belts, the new type belt is characterized by the optimum geometric parameters of the tooth profile, which result in optimum stress distribution and less stress concentration, and is desirable to use on pumping units.
