【Abstract】 The transmission mechanism of a parallel straight push rod linear reducer is in fact a combination of two cam mechanisms. The design feature and working principle of this reducer are introduced. The method of force analysis of the reducer is proposed on the basis of a supposition of the distribution of contact pressure between the push rod roller and the gear rack. Equations for calculating the forces on part of the elements of the reducer are derived. An example of calculation is given.更多还原
