Device for detecting static and dynamic strength of automobile transmission bearing

Abstract

The invention discloses a device for detecting the static and dynamic strength of an automobile transmission bearing. Both sides of a test chamber in a front-rear direction are radially provided withradially loaded electric cylinders and lubricating oil heating devices, and the output shafts of the radially loaded electric cylinders are connected with a radial loading device, and the oil outletsof the lubricating oil heating devices are connected with an oil inlet of the test chamber through an insulating oil pipe. The oil outlet of the test chamber is in series connection with a first refrigerator through an oil pipe, and then is connected with oil return ports of the lubricating oil heating devices. Electric main shafts and the radially loaded electric cylinders are respectively arranged at both sides of the test chamber in the left and right direction. The output shafts of the electric main shafts are connected with the test shaft through a shaft coupler, and the output shafts ofthe axially loaded electric cylinders are connected with the axial loading devices. The device can simulate the transmission oil temperature, can control temperature and flow rate and has the functionof displaying flow at all times. The device realizes the detection of the load strength of the bearing of the automobile transmission under the static condition and the dynamic strength detection ofthe high-temperature dynamic rotation. The detection result is accurate and reliable and the detection efficiency is high.

Description

technical field [0001] The invention relates to a detection device, which is used for static strength detection and dynamic strength detection of automobile transmission bearings. Background technique [0002] Automotive transmissions must meet various requirements, including smooth shifting, high output power, compact structure, light weight, high efficiency and low noise, etc., and these requirements are getting higher and higher. Therefore, the performance of transmission bearings must also meet higher requirements, which is the basis for developing automotive transmission bearings. Due to the rapid development of new products for automotive transmission bearings, the verification of product dynamic strength and static strength is imperative, coupled with the continuous replacement of materials, adjustment of heat treatment parameters, process improvement, etc., the detection of dynamic strength and static strength is required, but At present, there is no device speciall...
