Tooling device for bearing airtightness and dustproof performance detection

Abstract

The invention provides a tooling device for bearing airtightness and dustproof performance detection. The tooling device comprises a support positioning shaft, a water jacket, a water inlet pipe, a motor lifting rack, a positioning rod, a hammer plate and an airtight bearing; a middle segment of a motor rotating shaft is subjected to thickening turning operation; when the motor rotating shaft is plugged in the airtight bearing, a shaft shoulder formed via the thickening turning operation slides down to be abutted against an inner ring of the airtight bearing; a top abutting ring is welded on abottom part of the water jacket, four support rods are welded on the top abutting ring in a supported way so as to form a ring-shape true row, the water jacket is welded and suspended right below thea drive motor via the four support rods and arranged on a thickened shaft segment of the motor rotating shaft in a sleeving manner, and the water inlet pipe is welded on an outer rim of a top end ofa circumferential outer wall of the water jacket in a supported manner. Via arrangement of four groups of slip rings in the tooling device disclosed in the invention, the drive motor can be limited between four support positioning shafts to prevent the drive motor from shaking left and right during high speed rotation and twisting telescopic extension of two electric push rods.

Description

technical field [0001] The invention belongs to the technical field of bearing testing equipment, and more specifically relates to a tooling equipment used for testing bearing sealing performance and dustproof performance. Background technique [0002] The rapid development of industrialization makes the use of sealed bearings more and more extensive, and puts forward higher requirements for the reliability of the sealing performance of sealed bearings. In view of the unstable sealing effect of light contact sealed bearings used in medium and high speed speeds in my country, there is an urgent need for a tooling device for bearing sealing and dustproof performance testing. [0003] After retrieval, for example, the patent No. CN207439626U discloses a water pump bearing sealing performance detection tool, including a panel, a detection device, and an air supply device. The detection device includes a guide sleeve arranged on the upper end surface of the panel and a bottom su...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a tooling device for bearing sealing and dustproof performance testing to solve the problem that the existing bearing testing equipment has poor versatility, and most of them can only perform a single performance test, and cannot simultaneously It can well simulate the environment of water immersion and dust, and the bearing is embedded and clamped in the installation groove. After the test is completed, it is inconvenient to disassemble and take out the operation.
