Through the main structure such as the frame and loading mechanism, it realizes the accurate loading and monitoring of the radial force of the equipment to evaluate the performance, strength and stability of the equipment.
[0003] However, during the testing of radial transfer devices, how can we detect problems such as bearing overheating, damage, and bending that may occur when the bearing is subjected to radial (longitudinal) external force?
[0004] Therefore, a radial loading device for high-load test benches is needed to improve the above problems. Utility Model Content

A spacer is installed on the outer wall of the bearing. A U-shaped rubber sealing ring is provided on the outer wall of the spacer. A U-shaped rubber sealing ring is installed at the port of the spacer. A U-shaped rubber sealing ring is installed between the bearing and the radial bearing housing cover, and on the inner wall of the radial bearing housing cover. A skeleton oil seal ring is installed on the outer wall of the radial bearing housing cover. A lip seal ring is provided on the outer wall of the skeleton oil seal ring. A hexagon socket head cap screw is provided on one side of the lip seal ring, and on the outer wall of the skeleton oil seal ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. In this utility model, a radial loading cylinder in a radial loading device for a large load test bench is used. When the bearing rotates, only the control switch needs to be turned on so that one end of the radial loading cylinder applies a pulling force to the cylinder support base through the radial loading pin. This causes the cylinder support bases at both ends of the bearing housing welded parts to be subjected to the pulling force of the radial loading cylinder, thereby giving the entire device a downward force, which is gradually increased. This allows the system to detect the high temperature, breakage, wear, and deformation of the bearing during rotation when it is subjected to external force. This solves the problem of how to detect the bearing heating up, breakage, and bending during radial (longitudinal) external force pulling when testing a radial loading device.
