Analysis of Pressure Angle for a Straight Push Rod Linear Reducer

按活齿架、密齿齿条和稀齿齿条为固定件 3种情况 ,分别讨论了直线减速器的机构压力角并导出了相应的计算公式 ;提出了推杆相位间距的概念和校核机构压力角的方法。实例计算表明 ,文中提出的方法简便可行。

In order to evaluate the design plan of the linear reducer and provide the evidence to select the rack tooth form parameters of this kind of transmission, some problems about pressure angle of straight push rod linear reducer are discussed The moving gear shelf,the densely covered tooth rack and the sparsely covered tooth rack are respectively used as fixation device A calculation method of the mechanical pressure angle and its equations are also proposed A concept of phase distance of push rod and methods for calibrating the mechanical pressure angle are presented as well The illustration calculation shows that the methods proffered are simple and feasible
