Machine for testing reliability of service life of electromagnetic clutch bearing of automotive air conditioner

Abstract

The invention discloses a machine for testing the reliability of the service life of an electromagnetic clutch bearing of an automotive air conditioner, which solves the problem that the representation of data checked by the prior bearing testing machine is relatively poor because the prior bearing testing machine cannot well simulate the actual working condition of the electromagnetic clutch bearing of the automotive air conditioner. The testing machine comprises a frame, a bearing mounting base and a driving motor, wherein the bearing mounting base is arranged on a bedplate of the frame; the driving motor is connected with the tested bearing on the bearing mounting base by a drive mechanism; an encloser is arranged on the bedplate and covers the bearing mounting base; a heating plate and an induction device are arranged in the encloser; the induction device is used for sensing the change of a channel of the tested bearing and is connected with a central controller; and the heating plate is connected with the central controller.

Description

technical field [0001] The invention relates to a bearing reliability testing machine, in particular to an automobile air conditioner electromagnetic clutch bearing life reliability testing machine. Background technique [0002] Automotive air conditioner electromagnetic clutch bearing life reliability testing machine is generally installed next to the car engine, most of which are connected to the engine by a belt. The ambient temperature of the bearing is between minus 30 degrees and plus 130 degrees, which requires high precision of the bearing. In general bearing life reliability testing machines, the outer ring is fixed and the inner ring rotates, while the electromagnetic clutch bearing of an automobile air conditioner has an inner ring fixed and the outer ring rotates, and the temperature of the bearing during testing is room temperature, and the temperature during testing is relatively fixed. Therefore, there is usually a large gap between the life reliability testin...

AI Technical Summary

Problems solved by technology

The test bench with this structure can only detect one bearing to be tested at a time, and the representativeness of the detected data is relatively poor

Moreover, the ambient temperature in which the bearing is tested is relatively fixed, and the ambient temperature change of the electromagnetic clutch bearing of the automobile air conditioner cannot be reproduced well.
