Abstract

The invention discloses a measuring device for rolling friction force of a single sphere, which comprises a mounting assembly, a testing assembly and a driving assembly. The testing assembly comprises a wheel train testing system and a sensor group, the wheel train testing system is arranged on an anti-impact shield, the sensor group comprises a torque sensor and a load sensor, and the load sensor is arranged on the upper side of the wheel train testing system; the wheel train testing system comprises a first driving wheel, a second driving wheel and a driven wheel. The first driving wheel is rotationally arranged on the side portion of the driven wheel, and the second driving wheel is rotationally arranged below the driven wheel. The high-speed test is carried out on the bearing roller and the bearing material, the pitting corrosion condition of the bearing roller in the loading high-speed rotation process is mainly verified, the method belongs to material-level tests, has guiding significance on bearing manufacturing, can be used for carrying out comparison tests on different materials under the same conditions, and is a verification means for establishing an evaluation system of the bearing material.

Description

technical field [0001] The invention relates to the technical field of measuring the rolling friction force of a single sphere, in particular to a measuring device for the rolling friction force of a single sphere. Background technique [0002] Bearings will be damaged during use. The damaged position is generally on the rollers, inner and outer rings of the bearing. This will identify the damage to the bearing rollers and inner and outer rings, and analyze which one is damaged and whether the material is Reasonable. At present, there is no test equipment for this phenomenon. There is a lack of testing machines related to the materials of the inner rollers and inner and outer rings of the bearings. The functional indicators and service life of the bearing, but the specific cause of the internal damage of the bearing cannot be determined. [0003] The existing technology is based on the running-in test of the bearing, and the performance of the entire bearing is tested and e...
