Vertical Rack And Pinion Drive System

By selecting the complete drive system all at once a system can be optimized for the servo motor while achieving the desired accuracy and motion at the rack pinion.

Vertical rack and pinion drive system. 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. The units are operated by hardened tempered and ground steel rack and pinion helical teeth gears. Use an automatic lubrication system with felt gear applicator to maintain gearing quality and longevity. The pinion runs back and forth over the rack in fact a gear with an infinite radius.

Entering data in sizing software. Therefore keep the following in mind. They utilize our wide range of standard rack pinions quality levels from din 4 to. Tangential force on the rack.

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. A pinion of about 20 teeth is mathematically the optimum in terms of tangential force and system backlash. A larger pinion provides more backlash a smaller pinion can transmit lower torques and has a higher wear. Selecting a suitable rack and pinion drive for an application also includes determining the required gear.

In a vertical application the load moves in the direction of the guide system so the force due to the moved mass is not affected by the coefficient of friction of the guide rails. A rack has the property that it can be infinitely long and the accuracy when assembled correctly does not decrease. Rack and pinion linear drive. Racks can be mounted together and are normally available in lengths from 500 mm up to 2000 mm.

This system consists of a standard range of straight spur circumferential pitch and helical racks and pinions. The perfect symbiosis of state of the art technology and many years of experience. 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. The rack and pinion system is the primary building block of a linear axis drive.

This makes it only harder to calculate the rack and pinion. Some include premium servogears and actuators with backlash less than 1 arc min efficiency to. Thus proper sizing is critical to ensure the new servomotor will be able to move and control the load on the rack system. Accelerations of up to 20 m s 2 2 g s repeatability values of 50 μm system single piece lengths between 700 and.

The built in lubrication kit allows the pinion to be easily greased for smooth operation and long life. Size the rack and pinion drive based on peak cycle forces.
