Vertical Rack And Pinion Drive System

Size the rack and pinion drive based on peak cycle forces.

Vertical rack and pinion drive system.

Our specialist knowledge extends from the coupling of gearbox motor pinion and rack to complete system solutions. Stem pinions have a small number of teeth cut onto the end of a shaft. The pinion runs back and forth over the rack in fact a gear with an infinite radius. These systems are available in five levels of precision to meet any axis drive requirements.

The perfect symbiosis of state of the art technology and many years of experience. A rack has the property that it can be infinitely long and the accuracy when assembled correctly does not decrease. Tangential force on the rack. Racks can be mounted together and are normally available in lengths from 500 mm up to 2000 mm.

Thus proper sizing is critical to ensure the new servomotor will be able to move and control the load on the rack system. Pinion gears pinion gears are small toothed gears used to drive racks and turn rotational motion into linear motion. Pinion wires are drawn through a die to cut gear teeth into the. A larger pinion provides more backlash a smaller pinion can transmit lower torques and has a higher wear.

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 pinion of about 20 teeth is mathematically the optimum in terms of tangential force and system backlash. Use an automatic lubrication system with felt gear applicator to maintain gearing quality and longevity. The built in lubrication kit allows the pinion to be easily greased for smooth operation and long life.

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. 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. Accelerations of up to 20 m s 2 2 g s repeatability values of 50 μm system single piece lengths between 700 and. Entering data in sizing software.

They utilize our wide range of standard rack pinions quality levels from din 4 to. Rack and pinion linear drive. 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. Pinion gears are available in stem and wire forms.

This makes it only harder to calculate the rack and pinion. Selecting a suitable rack and pinion drive for an application also includes determining the required gear. They work with spur gears instead of racks. Some include premium servogears and actuators with backlash less than 1 arc min efficiency to.
