Double rotor test machine for cylindrical roller bearings

Abstract

Provided is a double rotor test machine for cylindrical roller bearings. The double rotor test machine comprises a body frame, a rotor shaft, a radial loading device, and a monitoring device, wherein the rotor shaft is arranged on the body frame, and the radial loading device is arranged above the rotor shaft and is fixedly connected with the body frame; the rotor shaft is in turn provided with a first assistant test device, a test bearing fixture and a second assistant test device; the two ends of the rotor shaft are also respectively provided with a support device; the rotor shaft is composed of an inner rotor shaft and an outer rotor shaft; a lower ring lubricating sleeve of the test bearing fixture is sleeved at the test end of the inner rotor shaft; a test bearing is sheathed on the lower ring lubrication sleeve; the outer ring of the test bearing is pressed in the inner hole of outer rotor shaft test end; the support device comprises an axially loaded bearing and a support bearing arranged in parallel, the supporting bearing is positioned inside of the axially loaded bearing, and an axial loading device is also arranged outside of the axial loading bearing. The test process of the double rotor test machine for the cylindrical roller bearings is scientific and can effectively test various parameters of large bearings at high speed.

Description

technical field [0001] The invention relates to a bearing testing machine, in particular to a cylindrical roller bearing double-rotor testing machine. Background technique [0002] Bearing is an important and key basic component in equipment manufacturing, which directly determines the performance, reliability and life of the equipment; due to the harsh working environment and complex load conditions of the bearing, it must be long enough or even the entire life cycle of the equipment to avoid Maintenance, etc. During the design, development and manufacturing process, the bearings must be verified on the testing machine for corresponding simulated working conditions to provide reliable test data for research, design, manufacture and use, and provide a basis for the design, manufacture and use of bearings . The R&D, design, manufacture and test technology of high-temperature and high-speed precision inter-axial bearings are mainly monopolized by a few foreign countries. The ...

Problems solved by technology

The R&D, design, manufacture and test technology of high-temperature and high-speed precision inter-axial bearings are mainly monopolized by a few foreign countries. The research and development of this type of testing machine in my country began in the 1970s and 1980s. Due to the limitations of design and manufacturing at that time, The inner and outer diameters of test bearings are also limited to medium and small sizes, and the limit speed is also low, which cannot meet the current test requirements for inter-shaft bearings with an inner diameter greater than 110mm and an outer diameter greater than 140mm, high temperature and high speed

[0003]Especially for high-temperature, high-speed precision inter-axial cylindrical roller bearings whose inner and outer rings rotate at the same time during operation, the test standards are more stringent because of the harsh working environment , there is no dual-rotor testing machine that can complete the test of large-size, high-speed, and heavy-load cylindrical roller bearings in the existing test equipment
