Results of investigations devoted to the synthesis of a new diversity of rack-and pinion gearings - rack-and-pinion inverse engagements - are presented. Designs of rack-and pinion gearings and rack-and-pinion inverse engagements are described. Force diagrams of these transmissions are considered in the end section with the traction mode of the forward and reverse movement. The responses are found during the mode of the forward and reverse movement in the engagement of the rack-and pinion inverse transmission and compared with responses in typical rack-and-pinion transmissions.
