Embodiment Construction

[0047] Embodiment 1 of the slewing bearing sealing test device of the present invention, as figure 2 As shown, the slewing bearing sealing test device includes an outer ring cover 10 , an inner ring cover 11 , an inflation joint 14 and a pressure detection device 15 .

[0048] In this embodiment, the bearing to be tested is a slew bearing with a ball hole provided on the outer ring. The outer ring cover 10 is sealed and connected to the end surface of the bearing outer ring 1 facing away from the sealing ring 9, and the inner ring cover 11 is sealed. Connected to the end of the bearing inner ring 4 close to the sealing ring 9, the outer ring cover 10, the outer ring 1, the sealing ring 9, the inner ring 4 and the inner ring cover 11 are sequentially connected to form a closed inner cavity, and the outer ring 1 and The space between the slideways of the inner ring 4 for accommodating rolling elements, spacers and lubricating grease is a part of the closed cavity.

Abstract

The invention provides a seal testing device and system for a rotary disc bearing. The seal testing device comprises an outer ring sealing cap used for being connected with the end surface of one side, backing on the sealing ring, of the outer ring of the bearing in a sealing mode, and further comprises an inner ring sealing cap used for being connected with the end surface of an inner ring of thebearing in a sealing mode; after the outer ring sealing cap and the inner ring sealing cap are connected with the bearing, and a sealing inner cavity is enclosed by the outer ring sealing cap and theinner ring sealing cap and the bearing; a gas charging connector used for being connected with a high-pressure gas source and charging compressed gas into the sealing inner cavity is arranged on oneof the outer ring sealing cap and the inner ring sealing cap, a pressure detecting device used for communicating with the sealing inner cavity is further arranged on one of the outer ring sealing capand the inner ring sealing cap, and the pressure detecting device judges the sealing property of the bearing by detecting whether the pressure in the sealing inner cavity changes or not. According tothe sealing testing device and system for the rotary disc bearing, the rotary disc bearing does not need to be subjected to installation detection, and the problem that the seal testing efficiency islow due to installation and dismantling is solved.

Description

technical field [0001] The invention relates to a sealing test device and a sealing test system of a turntable bearing. Background technique [0002] Slewing bearings are widely used in large-scale slewing devices such as lifting conveyors, mining machines, wind power generation, and radars because of their good axial load-bearing performance. The specific structure of the slewing bearing in the prior art is as figure 1 As shown, it includes the outer ring 1, the inner ring 4, and the rolling elements 3 and spacers 6 arranged alternately between the raceways of the outer ring 1 and the inner ring 4. The fixed outer ring positioning threaded hole 2 on the slewing device, and the inner ring 4 is provided with an inner ring positioning threaded hole 5 for fixing the inner ring 4 on the slewing device. In order to install the rolling element 3 and the spacer block 6 between the raceways of the outer ring 1 and the inner ring 4, a ball loading hole is provided on the outer ring...
