摘要
以魔芋精粉机第4级传动系统为研究对象,分别基于直齿同步带与新齿廓人字齿同步带建立多体动力学模型,分析齿线形状对带齿应力及系统振动的影响,探究螺旋角、齿间错位系数结构参数对传动系统动力学性能的影响规律。结果表明,当带齿螺旋角β=30°、齿间错位系数k=0.00时,带齿齿根应力更小、应力分布更均匀、横向振动更小、传动误差更低、干涉量波动更小。
Taking the fourth-stage transmission system of the konjac flour machine as the research object,a multi-body dynamic model was established based on the straight tooth synchronous belt and double helical synchronous belt with new profile,and the influence of the tooth line shape on the belt tooth stress and system vibration was analyzed.Then the influence of the structural parameters of the helix angle and the dislocation coefficient between the teeth on the dynamic performance of the transmission system were investigated.The results showed that when the toothed helix angleβwas 30°with the inter-tooth dislocation coefficient k of 0.00,the tooth root stress of the belt tooth was smaller.Under this condition,the stress distribution was more uniform,and the lateral vibration was smaller,with lower transmission error and smaller interference fluctuation.
