Automobile hub bearing slurry salty liquor and general durability test method and test machine

Abstract

The invention provides mud saline of wheel hub bearing of automobile and a general endurance test method. In the test method, a testing bearing is supported on a testing table in the cantilevered way; a loading shaft is used for driving the coating of the testing wheel hub bearing to rotate at the same speed as the rotating speed in the actual working status; the axial load and the radial load can be respectively or simultaneously exerted on the testing wheel hub bearing; the axial load and the radial load, which are exerted by the testing wheel hub bearing, are exerted on the coating of the testing wheel hub bearing which rotates at a high speed, through a loading arm which is vertical to the loading axle, a loading sleeve which is fixedly linked with the loading arm and arranged on the loading axle, a support loading arm, and a pair of conical rollers; thus the coating of the testing wheel hub bearing can rotate at a high speed and simultaneously is provided with the exerted axial load and the radial load; a water spraying device is used for directly spraying the mud saline to the testing wheel hub bearing (17) with the external load; a temperature sensor (18) is arranged on the non-rotating end face of the testing wheel hub bearing; and a vibration sensor (19) is arranged in the position of the fillet of the testing wheel hub bearing.

Description

technical field [0001] The invention belongs to bearing test and detection technology, and mainly relates to a mud salt water and general durability test method and a test machine of an automobile hub bearing. Background technique [0002] Automobile hub bearings are the most important transmission components in automobiles. With the development of the automobile industry, the structure of the automobile hub bearing has been improving, from the earliest simple bearing structure to the design of the bearing, the bearing sleeve, and the flange connected to the automobile hub, which is called the automobile hub bearing. , the automobile hub bearing plays a very important role in the operation of the automobile. With the high-speed rotation of the automobile transmission shaft, it bears the axial and radial loads during operation and operates under severe weather and road conditions. Its condition during long-term operation , fatigue and other information needs to be tested and...

AI Technical Summary

Problems solved by technology

At present, there is no well-designed automobile wheel bearing testing machine and relatively scientific and reasonable test and detection methods, which are not compatible with the rapid development of the automobile industry, and also restrict the further improvement and perfection of the automobile wheel bearing structure.
