Downward wall extension, wall extension and the connecting shaft of detection turntable bottom form annular receiving cavity；The annular wall of bearing disk is set
In in the annular receiving cavity of detection turntable, the connecting shaft for detecting turntable is arranged in the installation cavity on bearing disk, in annular
The first angular contact ball bearing is provided with the outside of wall on step surface, the second corner connection is installed outside the connecting shaft of top in installation cavity body
Ball bearing is touched, the upper surface of the second angular contact ball bearing is resisted against limit protrusion bottom, the lower face of the second angular contact ball bearing
It is resisted against on the spacer ring being arranged on outside connecting shaft, nut is provided with below spacer ring, nut is threadedly coupled with connecting shaft outside wall surface.
The connecting shaft bottom is connected with drive shaft, the bottom of drive shaft and the planet tooth being connected to below supporting table
Wheel decelerator connects, and planetary reducer is connected with motor.
The connecting shaft is connected with drive shaft using general flat key.
The bearing disk is connected by screw in the upper surface of supporting table.
The beneficial effects of the invention are as follows：The present invention designs bearing disk by design between detection turntable and supporting table,
Angular contact ball bearing is installed on bearing disk, due to the good axially loaded ability of angular contact ball bearing, makes detection turntable tilt quantity
It is maintained within claimed range.The configuration of the present invention is simple, transformation is convenient, highly practical, the detection particularly suitable for relief valve
Middle application.
