Rack And Pinion Gear Design Pdf

Rack and pinion combinations are often used as part of a simple linear actuator where the rotation of a shaft powered by hand or by a motor is converted to linear motion.

Rack and pinion gear design pdf.

Rack and pinion steering one of the most common application is the rack and pinion steering. Basic rack and. Gear racks are utilized to convert rotating movement into linear motion. When you turn the steering wheel the gear spins moving the rack.

You benefit from minimum assembly work and fast start up. This force thus torque may still be substantial and so it is common. A circular gear called the pinion engages teeth on a linear gear bar called the rack. Modular system purchase the rack and pinion drive as individual components as a gearbox with matching pinion and rack.

The results of the design shows that weight of new rack and pinion gearbox is 20 less than the oem rpg with nearly 40 reduction in the cost achieving the desired steering ratio. The rack carries the full load of the actuator directly and so the driving pinion is usually small so that the gear ratio reduces the torque required. A gear rack has straight teeth cut into one surface of a square or round section of rod and operates with a pinion which is a small cylindrical gear meshing with the gear rack. Rotational motion applied to the pinion causes the rack to move relative to the pinion thereby translating the rotational motion of the pinion into linear motion.

The tie rod at each end of the rack connects to the steering arm on the spindle. Rack and pinion drive with pinion pre mounted on the output shaft of the gearbox. A rack and pinion is a type of linear actuator that comprises a pair of gears which convert rotational motion into linear motion.
