What is the purpose of recirculating ball type steering gear?
What is the purpose of recirculating ball type steering gear?
The balls serve to reduce friction and wear in the gear, and reduce slop. Slop, when the gears come out of contact with each other, would be felt when changing the direction of the steering wheel, causing the wheel to feel loose.
Which is better rack and pinion or recirculating ball?
Rack and pinion provides less mechanical advantage than other mechanisms such as recirculating ball, but less backlash and greater feedback, or steering “feel”. The mechanism may be power-assisted, usually by hydraulic or electrical means.
How does recirculating ball steering work?
When the steering wheel turns, it turns the bolt. Instead of twisting further into the block the way a regular bolt would, this bolt is held fixed so that when it spins, it moves the block, which moves the gear that turns the wheels.
What are two advantages of mounting the re circulating ball steering box behind?
The gearset accomplishes two things. First, it converts the rotational motion of the steering wheel into a linear motion needed to turn the front wheels, and secondly, the gearset provides gear reduction, which lessens the effort needed to turn the wheels.
How does recirculating ball steering work on a truck?
Recirculating-ball steering is used on many trucks and SUVs today. The linkage that turns the wheels is slightly different than on a rack-and-pinion system. The recirculating-ball steering gear contains a worm gear. You can image the gear in two parts.
Why do you need balls in steering gear?
The balls actually serve two purposes: First, they reduce friction and wear in the gear; second, they reduce slop in the gear. Slop would be felt when you change the direction of the steering wheel — without the balls in the steering gear, the teeth would come out of contact with each other for a moment, making the steering wheel feel loose.
How does rack and pinion steering gear work?
The combined tolerances of each joint stacks up, which is more than 1/8 inch play in the linkage. A rack and pinion steering gear uses a pinion gear to convert the rotation of the steering wheel into the lateral movement of the rack gear.
How does power steering work in a car?
There are a couple of key components in power steering in addition to the rack-and-pinion or recirculating-ball mechanism. The hydraulic power for the steering is provided by a rotary-vane pump (see diagram below).

How does a steering wheel work in a car?
The steering wheel connects to a threaded rod, similar to a bolt, that sticks into the hole in the block. When the steering wheel turns, it turns the bolt. Instead of twisting further into the block the way a regular bolt would, this bolt is held fixed so that when it spins, it moves the block, which moves the gear that turns the wheels.
