Abstract

The invention discloses a detection device for press-mounting quality of a bearing sealing device. The detection device comprises a measuring table, a rotating mechanism, a bearing supporting mechanism and a locating mechanism. The rotating mechanism comprises a pair of rollers and a rotating ring; the rotating ring is arranged in an arc-shaped groove of the measuring table and is supported by therollers, and two locating holes are radially formed in the outer periphery of the rotating ring in a central symmetry manner; the bearing supporting mechanism comprises two supporting flat plates andfour supporting rods; the two supporting flat plates are fixed to the internal surface of the rotating ring, and the spacing of the two supporting flat plates is adaptive to the outside diameter of abearing to be detected; the four supporting rods are fixed to two sides of the two supporting flat plates, and the spacing of each pair of supporting rods is adaptive to the height of an outer ring of the bearing to be detected; the locating mechanism comprises a locating bracket and a locating pin; and the locating pin penetrates through a through hole in the locating bracket, then sequentiallypenetrates through a spring and a pressing plate and are abutted against the outer periphery of the rotating ring. According to the detection device disclosed by the invention, the mounting quality ofthe bearing sealing device can be efficiently and accurately measured.

Description

Technical field [0001] The invention relates to a bearing measuring device, in particular to a testing device for the press fitting quality of a bearing sealing device. Background technique [0002] Among the components of railway freight cars, bogie rolling bearings are very critical, and their press-fitting quality directly affects the quality of safe and reliable train operation. Railway freight car bearings are double-row tapered roller bearings without axle boxes. Since the truck bogies are not equipped with axle boxes, the bearings need to have their own sealing devices. The sealing device is not in contact with its relative moving parts, and there is a seal with appropriate clearance. This type of seal produces almost no frictional heat and wear during work, and is especially suitable for high-speed and high-temperature applications. Therefore, the installation of the sealing device will directly affect the use of the bearing. The installation requirements of the bearin...
