Which vehicles use worm and nut type steering?
Recirculating ball, also known as recirculating ball and nut or worm and sector, is a steering mechanism commonly found in older automobiles, off-road vehicles, and some trucks.
What is worm and ball bearing nut steering?
The recirculating ball nut steering system is very similar to the worm & nut mechanism. It has helical grooves on the steering gear (worm). As the driver rotates the steering, the steering column turns the worm gear on the end of the shaft. It moves the recalculating the balls and causes the steering linkage to move.
What is a worm type steering box?
The worm and sector steering box was one of the first steering box designs. It comprises a steering wheel shaft with a “worm” screw on the end, and a section gear that is moved up and down as the steering wheel turns.
What is a worm gear in steering?
Worm and Sector Steering Operation: In this type of steering mechanism, the steering shaft has a worm gear attached to it at its end. When you turn the steering wheel, the steering shaft turns the worm gear. The sector gear rotates around its axis as its teeth move along the worm gear and moves the P itman arm.
What is worm and worm gear?
Worms and worm gears are gear sets that offer high gear reduction and torque multiplication with a small footprint. A worm drive is a cylindrical gear with a shallow spiral thread that engages the worm gear in a non-intersecting, perpendicular axes configuration.
How does worm and peg steering work?
In worm-and-peg steering the worm moves the drop arm by means of a peg connected to a fork. The nut system has hardened balls running inside the thread between the worm and the nut. As the nut moves, the balls roll out into a tube that takes them back to the start; it is called a recirculating-ball system.
How many types of steering BOXS are there?
Worm and Wheel Steering Gear. Worm and Roller Steering Gear. Re-circulating Ball type Steering Gear.
How many types of worm gearboxes are there?
There are primarily three types of worm gear – Non-throated, single-throated and double-throated.

What is worm and ball bearing nut steering gear?
In the worm and ball bearing nut steering gear, a ball nut is mounted on the worm of the steering shaft. The worm and the nut have mating spiral grooves in which steel balls circulate to provide a frictionless drive between the worm and nut. Two sets of balls are used, with each set operating independently of others.
What is a worm shaft on a steering column?
In vehicles with the collapsible style steering column the worm shaft is SECTOR GEAR WORM GEAR shortened and protrudes out PITMAN SHAFT of the steering PITMAN ARM box as a stub shaft. This stub shaft is connected by a coupler (rag joint) to another shaft that the steering wheel is mounted on.
How does a steering wheel nut work?
A box type nut is clamped on this worm which has numerous ball bearings circulating between the worn and the nut. As the steering wheel on top of the steering column is turned, the nut moves up and down. This movement of the nut is sensed by the sector of the pitman which is connected to the nut.
What is a Saginaw recirculating ball&nut steering gear?
By the mid-’50s every General Motors vehicle car and truck, whether manual or power steering equipped, came with the patented Saginaw recirculating ball and nut steering gear. This type of steering gear is very low in friction and provides adequate mechanical advantage for the vehicle.
