The outer ring of the right shaft system bearing is axially limited.
[0036] The torque meter receiver support 19 is used to mount the torque meter's receiving module and receive torque meter signals.

The outer gasket and lock nut spacer are installed on the spline side of the input shaft, with a single-sided clearance of 0.1mm. The torque meter adapter support device has a sealing function. The locking nut spacer is pressed by the flange mounted on the spline, and the outer gasket is pressed by the outer end cover of the bearing housing. A baffle plate is installed on the outer side of the outer end cover of the bearing housing to prevent the low air pressure generated by the rotating shaft from drawing out the lubricating oil in the support. An outer gasket and an inner end cover of the bearing housing are installed on the flange side of the input shaft, with a clearance of 0.1mm on each side for sealing. The outer ring of the bearing in the shaft structure on the left side of the torque meter adapter support device is not axially limited, which facilitates the installation and disassembly of the torque meter. The difference between the right and left sides of the torque meter adapter support device is that the upper and lower housings of the output end limit the bearing on the left side, and an output shaft spacer is added outside the bearing on the right side. The output shaft spacer, the outer ring of the bearing, and the outer gasket are pressed by the outer end cover of the bearing housing.
