Interpretation of common faults of bearings

1 The bearing temperature is too high When the equipment is running, the part where the bearing is installed is allowed to have a certain working temperature. When stroking the bearing chamber of the equipment with hands, it is generally normal that it does not feel...

The main method to prevent metal rust

(1) Choose corrosion-resistant materials Mainly use non-ferrous metal alloys and stainless steel. (2) Prefabricated metal (alloy) or non-metal covering layer on metal surface 1. Conversion coating: blackening (bluish), phosphating, anodic oxidation; 2. Surface...

How to correctly understand the limit speed of the bearing

The limiting speed of the bearing is the highest speed that the bearing can reach when the bearing is running. It mainly depends on the relationship between the heat generated by friction and the heat discharged when the bearing is running, and the bearing material,...

What are the solid lubricants that can be used for bearings

The main function of the bearing is to reduce friction and reduce loss, so during use, the less contact between the bearing and surrounding parts, the better. Then, if lubricants are used, the effect of reducing losses will be better. In fact, lubricants include...

Selection and Design of Bearings for Vibration Machinery

Vibrating screens are used to convey or screen loose materials and are used in mines, quarries, stone crushing plants, foundries, food industry, chemical industry and many other material preparation and processing plants. The main types of vibrating screens are:...

Basic method of fault diagnosis of rolling bearing

Regarding the fault diagnosis methods of rolling bearings, traditionally, people mainly classify them according to the state quantities used in monitoring and diagnosis, that is, according to the nature of the measured signals. According to this classification method,...

What is the main function of lubricant

Rolling bearing is an important mechanical component. Whether the performance of a mechanical equipment can be fully developed depends on whether the bearing is lubricated properly. It can be said that lubrication is a necessary condition for the normal operation of...

The main reason and solution of bearing running heat

1. The small bearing clearance leads to running heat a. When the interference is too large, repair the shaft or replace the bearing with large clearance; b. Adjust the end cover when the axial preload is too large; c. When there is too much dust in the bearing, clean...

The main factors affecting bearing corrosion

1.Relative humidity of the atmosphere Absolute humidity: the weight of water vapor per unit volume of air (g/m3) Relative humidity: The ratio of the water vapor content in the air to the saturated water vapor content of the air at the same temperature, expressed as a...
