Rack And Pinion Gear Calculation

The calculator supports both straight tooth and helical rack and pinion pairs.

Rack and pinion gear calculation.

The rack and pinion calculator instantly generates the tooth profiles of the involute gear and meshing rack with trapezoidal teeth based on the number of teeth on the pinion module pressure angle and profile shift. Rack and pinion drive calculation and selection the values given in the load table are based upon uniform smooth operation khß 1 0 and reliable grease lubrication. 3 rack and spur gear table 4 5 presents the method for calculating the mesh of a rack and spur gear. 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.

In stock and ready to ship. Measure the distance from the end of the rack to an arbitrary point turn the pinion one full revolution and then measure the distance again. The difference between the two is the gear ratio. 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 torque on the pinion is simply the tangential force force on the rack divided by the pinion radius. T p torque on pinion nm ft lb r p pinion radius m ft. Since in practice the applications are very diverse it is important to consider the given conditions by using appropriate factors sb k. Hardness of the rack.

Calculating rack and pinion gear ratio instead of counting the number of teeth in each gear measure the distance the rack moves in inches. The following are calculations for center distance a and tip and root clearance c when module m 2 pinion z 1 20 gear z 2 40 reference diameter of pinion d 1 20 2 40 reference diameter of gear d 2 40 2 80. Figure 4 3 1 shows the the meshing of standard gear and a rack. Rack and pinion 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.
