Air cylinder parallel type self-aligning roller bearing positive and negative pressure loading device

Abstract

The invention discloses an air cylinder parallel type self-aligning roller bearing positive and negative pressure loading device, which comprises a rack and an air cylinder connecting transverse plate, wherein a positive pressure air cylinder and a negative pressure air cylinder are arranged on the rack, the positive pressure air cylinder is fixedly connected with an adjusting plate, and a pistonjoint of the positive pressure air cylinder is fixedly connected to the air cylinder connecting transverse plate; the negative pressure air cylinder is fixedly connected with a follow-up rotating bodyseat, and a piston joint of the negative pressure air cylinder is also fixedly connected to the air cylinder connecting transverse plate; the device further comprises an inner ring pressing ring andan outer ring pressing ring, spaces used for containing the measured bearing are arranged in the inner ring pressing ring and the outer ring pressing ring, a follow-up bearing is arranged in the follow-up rotating body seat and arranged on the rotating shaft in a sleeving mode, one end of the rotating shaft is fixed to the inner ring pressing ring, and the other end of the rotating shaft is fixedto the air cylinder connecting transverse plate. The negative pressure air cylinder and the two positive pressure air cylinders are arranged in parallel, so that the structure is compact; loading force in the upper direction and the lower direction can be provided through positive pressure measurement and negative pressure measurement respectively, and two times of measurement can be completed through one-time clamping.

Description

technical field [0001] The invention relates to the technical field of bearing testing, in particular to a positive and negative pressure loading device for cylinder parallel type spherical roller bearings. Background technique [0002] The self-aligning roller bearing has two rows of rollers, so when performing vibration measurement, it is necessary to provide axial force to the two rows of rollers for measurement. The existing measurement method is manual clamping, that is, after one side is measured, the bearing is manually taken out and rotated 180°, and then the clamping measurement is performed. The loading force of this measurement method is in a single direction. Although the structure is simple, the manual clamping workload is heavy. It is only suitable for sampling inspection or occasional use in the laboratory, and is not suitable for online measurement in the workshop. [0003] Therefore, there is an urgent need for a spherical roller bearing loading device that...
