Rack And Pinion Gear Design Calculator

Unlike ball screw sizing which must take into account factors such as characteristic and critical speeds end bearing considerations and the effects of preload in addition to basic thrust force and drive torque calculations rack and pinion drive sizing is primarily based on three factors.

Rack and pinion gear design calculator. The following online calculator computes the basic dimensions and tooth profiles of a meshing rack and pinion based on the pinion s module number of teeth pressure angle usually 20 and profile shift. 3 rack and spur gear table 4 5 presents the method for calculating the mesh of a rack and spur gear. An important principle is that you realize that the calculation and selection rack pinion gearbox and motor is done by trial and error. The force the rack sees.

Basic rack and. You have a good chance that you have to do the calculations again with other parameters such as the diameter of the pinion or the quality read in this case. Because gear calculations require many complex formulas related to strengths and sizes traditional gear design situations require highly specialized knowledge and suitable design time. In the example above the12 tooth pinion was given sufficient correction to prevent undercut and the residual profile shift was given to the mating gear.

The results of the design shows that weight of new rack and pinion gearbox is 20 less than the oem rpg with nearly 40 reduction in the cost achieving the desired steering ratio. The rack s teeth are trapezoidal while the pinion has an involute tooth profile.
