Abstract

The invention relates to a bearing rolling body rolling friction force measuring system and a loading device thereof, and the system comprises: a test bench, wherein the loading device is supported and matched above the test bench, a loading support is correspondingly provided with a loading sleeve, and the loading support is in transmission connection with a loading driving mechanism; a loading sleeve, wherein a wheel seat and a loading wheel are arranged in the loading sleeve; a wheel seat, wherein a loading wheel is rotationally assembled on the wheel seat; a loading wheel which axially extends in the front-back direction and is used for being in direct contact with the bearing rolling body and loading the bearing rolling body in the radial direction of the bearing rolling body; and deformable bodies on the two sides which are arranged in bilateral symmetry about the central axis of the loading wheel, the upper ends of the deformable bodies can swing left and right relative to the lower ends of the deformable bodies, the upper ends of the deformable bodies are fixedly connected with the wheel seat, and the lower ends of the deformable bodies are fixedly connected with the loading sleeve. According to the system for measuring the rolling friction force of the bearing rolling body, the bearing rolling body is separated from the rolling bearing, so that the interference of other factors in the bearing during the measurement of the rolling friction force of the bearing rolling body is eliminated.

Description

technical field [0001] The invention relates to a rolling friction measurement system of a bearing rolling body and a loading device thereof. Background technique [0002] Rolling bearings are very common parts in machines, which rely on the rolling contact between the main parts to support the rotating parts. Most of the rolling bearings in the prior art have been standardized, mainly including an inner ring, an outer ring, rolling elements and a cage, and the rolling elements correspond to the inner ring and the outer ring to form a friction pair in the rolling bearing. When the rolling element is working, it will slide and roll relative to the inner ring and the outer ring at the same time. The magnitude and direction of the friction force on the rolling element are complex and changeable. In order to ensure the service life and reliability of the rolling element and rolling bearing, it is necessary to Test and evaluate various friction and wear properties of rolling ele...

Problems solved by technology

[0004] However, when testing the entire rolling bearing, the bearing ring is mostly loaded. At this time, the force on the rolling element is complicated, and factors such as the bearing cage, end cover, and assembly preload will affect the rolling friction between the rolling element and the inner and outer rings. Force, the system factors in the bearing will lead to the inability to accurately measure the rolling friction of the rolling element, and it is also impossible to accurately evaluate the friction and wear properties of the rolling element. Therefore, it is necessary to develop a friction measurement system in order to avoid Bearing system factor interference
