Agricultural machinery bearing limit speed ratio raceway noise solution

The limiting speed ratio of rolling agricultural machinery bearings is the maximum speed ratio allowed under certain load and lubrication standards, and is related to the agricultural machinery bearing type, specification, load size and orientation, lubricant type and lubrication method, backlash, maintenance of steel frame structure and Refrigeration standards and many other factors are related.

Factors that affect the limit speed ratio include: load size, load type and orientation, lubricant and lubrication method. Experience has proven that improving the manufacturing precision of agricultural machinery bearings, appropriately increasing the side clearance of agricultural machinery bearings, and using unique materials and structures for ball agricultural machinery bearings can also increase the limit speed of agricultural machinery bearings.

The high temperature of agricultural machinery bearings is caused by the following factors: the quality of the grease does not meet the requirements or is moldy, the high viscosity of the grease; the high viscosity of the grease; the high viscosity of the grease; the tightness of the tissue (lack of space); the tissue Over-tightening of installation (insufficient space); over-tightening of one-way agricultural machinery bearings; over-tightening of agricultural machinery bearing seat rings on the shaft or on the agricultural machinery bearing housing or on the agricultural machinery bearing housing; oversized load; oversized load; Oversized load; oversized load; oversized load; oversized load; agricultural machinery bearing ball agricultural machinery bearing or ball agricultural machinery bearing or ball agricultural machinery bearing or ball agricultural machinery bearing body rupture, etc.

Rolling agricultural machinery bearings allow slight operating noise. If the noise is too loud or there are abnormal noises or knocking sounds, there is a common fault with the agricultural machinery bearings.

The reasons for the noise generated by rolling agricultural machinery bearings are very complex. One is the damage to the internal and external surfaces of agricultural machinery bearings. Due to this damage, the cooperation between the agricultural machinery bearing and the housing is destroyed. The cooperation between the single-sided agricultural machinery bearing and the axial direction causes an appropriate deviation of the axial direction and produces axial noise during high-speed movements. When agricultural machinery bearings fatigue, the metal materials on their surfaces will fall off, which will also expand the sound in the axial space of the agricultural machinery bearings. In addition, the agricultural machinery bearings are insufficiently lubricated, causing dry friction, grinding of the agricultural machinery bearings, and other abnormal sounds. After the agricultural machinery bearings are damaged and loosened, the balls will become loose and damaged, which will also cause damage to the noisy agricultural machinery bearings.

   When disassembling and inspecting rolling agricultural machinery bearings, common faults and damage causes of single-sided agricultural machinery bearings can be identified based on the damage of the agricultural machinery bearings. The so-called pressure-stabilizing preload is the use of compression springs and butterfly springs to provide an appropriate load in the form of production. When in use, even if the relative position of the agricultural machinery bearing changes, it is preloaded. What types of sealing properties are there for agricultural machinery bearings during application? , it even changes relative to the position, and the preload can remain constant.
