Abstract

The invention discloses a service life testing machine for an inner-ring-free cylindrical roller bearing, relates to a bearing service life testing machine, and aims to solve the problems that an existing bearing service life testing machine cannot meet the test working condition requirement of the inner-ring-free cylindrical roller bearing when the inner-ring-free cylindrical roller bearing for amain shaft of a gearbox is subjected to the bearing service life strengthening test. The service life testing machine comprises a base, an upper cover, a radial loading mechanism, a transmission shaft, an electric main shaft, two test accompanying bearings and two axial lubricating mechanisms, wherein the upper cover is arranged on the base, the transmission shaft is horizontally arranged on thebase, the transmission shaft is rotatably connected with the base through the two test accompanying bearings, the two axial lubricating mechanisms are arranged on the base outside the transmission shaft, the radial loading mechanism is arranged on the upper cover, the test bearing is sleeved on the transmission shaft, and one end of the transmission shaft 8 is fixedly connected with an output shaft of the electric main shaft. The machine is applied to the field of bearing testing.

Description

technical field [0001] The invention relates to a bearing life testing machine, in particular to a cylindrical roller bearing life testing machine without an inner ring. Background technique [0002] The support bearing for the main shaft of a certain type of automobile gearbox is a cylindrical roller bearing without an inner ring. At present, most of the imported bearings are used. The cost of imported bearings is relatively high, and most of the bearings cannot meet the requirements of the gearbox main shaft for the bearing environment. It is necessary to research and develop cylindrical roller bearings without inner rings for automobile gearboxes to replace imported bearings. Therefore, before the bearing is put into use, it is required to conduct a bearing life enhancement test on the cylindrical bearing without inner ring. The test speed of this series of bearings is within 5000r / min, and the radial load needs to be changed frequently, and the maximum radial load must m...
