A recirculating ball type steering gear is a kind of power steering device for vehicles.
It uses a recirculating ball nut and screwshaft to convert rotational motion into linear motion, and provides auxiliary steering force for the front wheels of the vehicle.
The recirculating ball nut has a circular path and an inner raceway, which are in sliding contact with balls.
The balls rotate in the circular path and move in the thread gap between the nut and screwshaft, reducing friction and wear.
The recirculating ball type steering gear is widely used in light and heavy vehicles and has the advantages of simple structure, convenient maintenance, high efficiency, and reliable performance.
