How to prolong the service life of bearings
Choose the right bearing
In order to select a more suitable bearing from a large number of structures and sizes, it is necessary to study from various angles. The specific method of bearing selection is as follows:
1. The bearing structure is determined
Considering the ease of arrangement, installation, and disassembly of the bearing as a shaft system, the allowable space and size of the bearing, and the marketability of the bearing, the bearing structure is roughly determined.
2. Service life
While comparing and studying the design life of various machinery using bearings and the various endurance limits of the bearings, the bearing size is determined. When selecting a bearing, it is often biased to consider only the fatigue life of the bearing. The grease life, wear and noise caused by the aging of the grease also need to be fully studied.
3. Determination of bearing use
According to different uses, it is necessary to select specially designed bearings for accuracy, clearance, cage structure, grease, etc. requirements. However, there is no certain order and rules for selecting bearings. The priority should be considered for the requirements of the bearing, performance, and more related matters, which is especially practical.
The effect of heat treatment on the material of cross roller bearing
Crossed roller bearings are a kind of bearings that are used more mechanically, especially in industrial machines. Of course, when we use them, we need to have better performance of crossed roller bearings to ensure the performance of crossed roller bearings. For various properties, then we need to perform heat treatment on its processed materials, so why do we need heat treatment? Let’s take a look! 1. Surface residual stress The distribution of surface residual stress of bearing steel after quenching is largely affected by the cooling rate and quenching medium. For the materials used in crossed roller bearings, heating to 840 ℃…
Causes of temperature rise during use of crossed roller bearings
Crossed roller bearings are also commonly used nowadays. Many machinery and equipment will choose crossed roller bearings. Crossed roller bearings are favored because they have good performance and mainly meet the needs of use. Bearings are always used when they are used. If you want to rotate, it will inevitably generate heat during the rotation, but there is also a situation where the overheating temperature gradually rises.
Let’s take a look! 1. The influence of lubricating oil 1. If the amount of lubricating oil used is too little or too much lubricating grease, it may cause the temperature to rise, so when using it, it should be in accordance with the requirements of usual work…
