Abstract

The invention relates to a double direction thrust bearing tester. A rolling bearing seat is arranged in an oil groove; the device is provided with two sets of thrust bearing devices between which a loading piston cylinder is arranged, and both ends of the loading piston cylinder are respectively connected with fixing plates at both sides of the thrust bearing; the two sets of rolling bearings are respectively arranged in the rolling bearing seat; two thrust discs are respectively arranged on an output shaft of a motor; the trust bearing is arranged between a fixing ring and the fixing plate;two sliding rods are respectively fixed on the rolling bearing seats passing through the respective fixing ring and the fixing plate, a sealing which is arranged on the output shaft of the motor is fixed at the side wall of the oil groove, and the output shaft of the motor is connected with the motor through a coupler. The double direction thrust bearing tester of the invention has simple installation and overhaul, and can effectively test and verify the performance of a double direction thrust bearing.

Description

technical field [0001] The invention relates to a bidirectional thrust bearing test device. Background technique [0002] Thrust bearing is one of the most important components in large hydroelectric generators and large gas turbines. Its working performance is not only directly related to the safe operation of the unit, but also affects the efficiency of the unit. With the improvement of the operating reliability of large-scale units, the requirements for thrust bearings are also higher. The thrust bearings in large gas turbines generally use imported bearings. In the localization research, the verification of the bearings is involved, and the risk of verification by the method of actual operation on the unit is too high, and the working conditions cannot be carried out according to the needs of the bearings. Adjustment. Contents of the invention [0003] The purpose of the invention is to disclose a bidirectional thrust bearing testing device which is simple to install...
