Abstract

The invention discloses a bidirectional double-time bearing airtightness detection device with a turnover clamping platform, and relates to the technical field of bearing airtightness detection, in particular to a telescopic rod, a bearing lower sealing mechanism, a lower sealing disc assembly and a bearing upper sealing mechanism. A bottom plate is fixed at bottom of the telescopic rod. The bearing lower sealing mechanism is arranged above the bottom plate, the lower sealing disc assembly is arranged above the bearing lower sealing mechanism, and the bearing upper sealing mechanism is arranged above the lower sealing disc assembly. According to the bidirectional two-time bearing airtightness detection device with the turnover clamping platform, air blowing operation on a bearing is achieved through two methods, one method is from bottom to top, and the other method is from top to bottom, so that bidirectional two-time air tightness detection on the same bearing can be achieved, and the sealing conditions of the two ends of the bearing can be well detected. Therefore, the airtightness detection result of the bearing is more accurate, and the detection efficiency is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of bearing air tightness detection, in particular to a bidirectional and double bearing air tightness detection device with a reversible clamping platform. Background technique

[0002] Bearing is a very common part used in the rotating body of various mechanical equipment. It mainly supports the mechanical rotating body, reduces the friction coefficient during its movement, and ensures its rotation accuracy. Bearings are essential in the mechanical rotating system , Also because of the particularity and importance of the bearing function, the sealing requirements of the bearing itself are also relatively high, because the quality of the sealing performance will directly affect the smoothness of the bearing.

[0003] Bearing tightness is mainly reflected in the connection between the inner and outer rings of the bearing. In order to ensure good oil lubrication of the bearing, a good seal must be maintained b...
