The recirculating-ball steering gear contains a worm gear. You can image the gear in two parts. The first part is a block of metal with a threaded hole in it. This block has gear teeth cut into the outside of it, which engage a gear that movesthe pitman arm (see diagram above). The steering wheel connects to a threadedrod, 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 theway 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.
Steering Worm Shaft with Steering ballnut and worm assembly
The production of nuts for your screw and nut assembly poses equally stringent quality requirements. Our own toolbuilding shop is evidence of our flexibility and commitment in the service of our customers - lead screw taps even in special forms are no obstacle, at least not for us. Complicated forms on screws or nuts in conjunction with a high accuracy requirement present as little of a problem as galvanization
The ball screw assembly steering gears consists of a screw and a nut, each with matching helical grooves, and balls which roll between these grooves between the nut and the screw when the nut or screw is rotating. The balls are deflected by the deflector into the ball return system of the nut and they travel through the return system to the opposite end of the ball nut in a continuous path, and exit from the ball return system into the ball screw and nut thread raceways continuously to recirculate in a closed circuit.
The ball nut assembly: Ball nut determines the load and life of the ball screw assembly.
The ratio of the number of threads in the ball nut circuit to the number Of threads on the ball screw determines how much sooner the ball nut will reach Fatigue failure (wear out) than the ball screw will. Ball nuts are manufactured With two types of return systems.
We can produce it according to your drawing,even with old samples! mainly for racing teams
