Bearing centrifugal testbed

Abstract

The invention discloses a bearing centrifugal testbed. The bearing centrifugal testbed comprises a bearing seat, a driving motor, and a testing table for mounting a to-be-tested bearing; the testing table is arranged on the bearing seat, a mounting slot is formed on the testing table, a spindle is arranged in the mounting slot, the spindle is arranged in the mounting slot through a bush, and a positioning slot is arranged on the bush; the spindle comprises a testing part, a balance weight part and a transmission part; the testing part is arranged at a bush corresponding location, a base plateis arranged on the testing part, the positioning slot and the base plate are combined to form the locking on a to-be-tested bearing; the transmission part is arranged at the external of the testing table, a belt pulley is sleeved on the transmission part, the belt pulley is connected with a driving part output end through a belt to form the driving on the rotation of the spindle by the driving motor; the balance weight part is arranged in the mounting slot, and an eccentric block is arranged on the balance weight part. The testbed disclosed by the invention is simple in structure, capable of testing the capacity for bearing the rotating load by the outer ring of the bearing, and the testbed can provide a certain vibration effect, and the testing is closer to the working environment.

Description

technical field [0001] The invention relates to the technical field of bearing testing equipment, in particular to a bearing centrifugal rotation test bench. Background technique [0002] The bearing is the "joint" of the machine, and the bearing has a vital influence on the performance of the equipment. Rolling bearings are usually used with the outer ring fixed and the inner ring rotating. However, in some actual working conditions, such as compactors or flywheels, the outer ring of the bearing is subjected to rotational loads, and the existing test benches cannot simulate similar working conditions. To provide a certain vibration effect for testing bearings, the existing testing equipment cannot provide a good vibration effect. At the same time, the existing test bench has a complex structure and is not convenient enough to operate. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a bearing centrifugal test...
