部分式大齿轮在矿山机械上应用广泛,由于矿山机械多为重载,冲击较大,故大齿轮的变形对设备本身影响较大。大齿轮变形的特征之一就是齿轮对口处开口,致使对口处的齿距变大.小齿轮的轮齿转到此处,啮合特性改变.产生冲击和振动。由于开口.致使大齿轮外圆形成椭圆,大齿轮转一圈,与小齿轮的啮合顶隙间隙发生周期变化。
Part of the large gear in the mining machinery widely used, due to mining machinery mostly heavy load, a larger impact, so the deformation of the gear larger impact on the equipment itself. One of the characteristics of the deformation of the gear is the opening of the gear counterpart, resulting in the larger pitch of the counterpart, the gear tooth of the pinion gear is transferred there and the meshing characteristic is changed, and the shock and vibration are generated. Due to the opening, the outer circle of the gearwheel is formed into an ellipse, the gearwheel rotates in a circle, and the gap of the top clearance which meshes with the gearwheel changes periodically.
