Abstract
The utility model relates to a rotor for a steering assisting pump of an automobile and belongs to the technical field of the steering assisting pump of the automobile. The technical problem to be solved is to provide the rotor for the steering assisting pump of the automobile, with a simple structure and invariable use state and technical index. According to the technical scheme, in the rotor for the steering assisting pump of the automobile, 10 ball slots are uniformly arranged on a rotor main body along a radial direction, an axle hole is arranged at the center of the rotor main body along the radial direction, a key slot is arranged on the axle hole, and the rotor main body is manufactured by adopting a powder metallurgy process. According to the rotor for the steering assisting pump of the automobile, the original blade slots are changed into the ball slots, the strength is not reduced, the use is not influenced and the processing is simplified. The rotor provided by the utility model is manufactured by adopting the powder metallurgy process, so that the production efficiency is greatly increased, the cost is saved, the material utilization is increased and the batch production can be carried out.
