Problems solved by technology

[0003] At present, before leaving the factory, the automobile steering gear needs to be tested by a special testing machine to test the performance and some parameters of the automobile steering gear; the working principle is as follows: through the special automobile steering gear testing machine Work, the testing machine detects various parameters of the steering gear in real time, because the decelerating worm gear inside the steering gear is currently an injection molded part, the surface is very smooth (there is no function of storing grease), resulting in abnormal noise of the steering gear when it is working, resulting in unqualified assembly The phenomenon

Abstract

The invention discloses worm gear running-in equipment of an automobile steering system, and relates to the technical field of worm gear running-in equipment. The worm gear running-in equipment comprises an equipment body, the equipment body comprises a left sliding table feeding mechanism, a positioning mechanism, a worm measurement stress application small sliding table, a right sliding table feeding mechanism, a detection mechanism and a hydraulic system. The positioning mechanism comprises a shell, a hydraulic clamping mandrel, a rotating main shaft and a clamping oil cylinder, the hydraulic clamping mandrel is fixed to the rotating main shaft, an inner circle clamping structure is arranged on the hydraulic clamping mandrel, a worm wheel is installed on the hydraulic clamping mandrel in a clamping manner through the inner circle clamping structure. An ejector rod is connected between the output end of the clamping oil cylinder and the rotating main shaft. The surface of the worm gear is improved through the equipment body, certain lines are added on the surface of the worm gear after running-in, a certain grease storage function is achieved, and abnormal sound can be greatly reduced or does not exist; and the quality of an automobile steering device is improved.

Description

technical field [0001] The invention relates to the technical field of worm gear running-in equipment, in particular to a worm gear running-in equipment for an automobile steering system. Background technique [0002] Automobile steering gear, also known as steering gear and steering gear, is the most important component in the steering system of an automobile. Its function is to increase the force transmitted from the steering wheel to the steering transmission mechanism and to change the direction of force transmission. [0003] At present, before leaving the factory, the automobile steering gear needs to be tested by a special testing machine to test the performance and some parameters of the automobile steering gear; the working principle is as follows: through the special automobile steering gear testing machine Work, the testing machine detects various parameters of the steering gear in real time, because the decelerating worm gear inside the steering gear is currentl...
