Vertical Rack And Pinion Drive System

Our specialist knowledge extends from the coupling of gearbox motor pinion and rack to complete system solutions.

Vertical rack and pinion drive system. The perfect symbiosis of state of the art technology and many years of experience. The modular design permits rack segment lengths from 0 5 to 2 meters to be linked together end to end achieving any desired travel length from standard components. This system consists of a standard range of straight spur circumferential pitch and helical racks and pinions. Therefore keep the following in mind.

Thus proper sizing is critical to ensure the new servomotor will be able to move and control the load on the rack system. The force the rack sees referred to as the feed force or tangential. Size the rack and pinion drive based on peak cycle forces. Throughout a proud history stretching back over 70 years alimak have become recognised for a culture of constant innovation and product development not least for pioneering the first mast climbing platform to utilise the hard wearing and reliable rack and pinion drive system.

A pinion of about 20 teeth is mathematically the optimum in terms of tangential force and system backlash. 30 years of experience in the fields of gearbox construction toothing technology and the design of complete drive systems go into our rack and pinion systems. Entering data in sizing software. 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.

We use a step by step approach to entering data into our motor and drive manufacturer software about the rack and pinion system to have the ability to select a servomotor. The rack and pinion system is the primary building block of a linear axis drive.
