Embodiment Construction

[0020] A special bearing simulation test machine driven by a central friction wheel for elevators, which is characterized in that: a friction wheel is set at the center of the panel of the test machine to drive the running of the bearing, and several sets of test bearings are arranged symmetrically in a planetary manner on the outer periphery of the test machine, adjustable The cylinder completely simulates the actual industrial and mining bearing state of the bearing. The air pressure is loaded on the test bearing and pressed against the outer wall of the friction wheel. The friction wheel drives each test bearing through the test parameters set in advance by the programmable controller to simulate the lifting, falling and stopping of the elevator. Do timing steering switching, acceleration and deceleration rotation and intermittent pause cycle running. At the same time, the temperature rise of the bearing is measured by connecting the temperature sensor to the test bearing. ...

Abstract

The invention relates to a center friction wheel driven-type special elevator bearing simulation tester, which comprises a motor, a speed changer and a friction wheel which is driven by the motor. An installation back plate which is perpendicular to the axis of the friction wheel is arranged among the friction wheel, the motor and the speed changer. A plurality of groups of guide rails which point to the center of the friction wheel are arranged on the installation back plate on the periphery of the friction wheel. Installation shaft bases which are driven by cylinders and slide along the guide rails are arranged on the guide rails. Installation core shafts which are used for installing bearings to be tested and are in parallel with the axis of the friction wheel are arranged on the installation shaft bases. Fixing devices used for axially fixing the bearings to be tested are arranged at the top ends of the installation core shafts. The center friction wheel driven-type special elevator bearing simulation tester has the advantages that the working condition simulation degree is high, the structure is reasonable and compact, the performance test is comprehensive, the energy consumption is low, the tester is convenient to operate, the tester can be used for verifying and improving bearing design and judging whether the product sealing and temperature increase characteristics and the service life of the bearings satisfy the design and use requirements or not, the test result contrast is increased and the test efficiency is improved.

Description

【Technical field】 [0001] The invention relates to a bearing testing machine, in particular to a double-row angular contact ball bearing unit sealing, temperature rise performance and operating life simulation testing machine for an elevator traction machine. 【Background technique】 [0002] The special sealed double-row angular contact ball bearing unit for the new gearless elevator traction machine mainly bears the weight load of the elevator car radially applied to the outer ring by the traction steel belt during operation. The inner ring is relatively fixed while the outer ring is in operation. It is driven by the friction of the traction steel belt to perform intermittent alternating direction-changing acceleration and deceleration, direction-changing rotation and rest. The running noise, temperature rise and sealing characteristics of the bearing unit directly affect the running stability and comfort of the elevator car and the cleanliness and tidiness of the elevato...
