Mechanical bearings are mechanical elements that support rotary or linear moving parts, mainly used to reduce friction between moving parts, bear loads, and ensure efficient and smooth operation of equipment. It is an indispensable core component of mechanical equipment, widely used in industry, automobile, aerospace, household appliances and other fields.
Reduce friction: through rolling or sliding contact, reduce the friction resistance between moving parts and improve the efficiency of equipment.
Supporting load: bear radial, axial or composite load, ensure the stability of the equipment in the case of force.
Precise Positioning: Maintains the precise position of rotary axes or linear moving parts to ensure the accuracy of equipment operation.
Transfer motion: transfer power from one part to another, to realize the normal operation of mechanical equipment.
According to the working principle and structure, mechanical bearings are mainly divided into the following categories:
Rolling bearings: such as deep groove ball bearings, cylindrical roller bearings, tapered roller bearings, etc. Friction is reduced by rolling bodies (such as steel balls and rollers).
Sliding bearings: such as bushings, tiles, through the lubricant in the sliding surface to form an oil film, reduce friction.
Special bearings: such as magnetic levitation bearings, air bearings, using non-contact technology to realize frictionless operation.
Mechanical bearings are usually composed of the following components:
Inner and outer rings: fit with shafts and housings to provide support and localization.
Rolling bodies: such as steel balls and rollers, which reduce friction and carry loads.
Cage: separates the rolling elements, prevents them from colliding with each other and ensures even distribution.
Seals or dust caps: prevent contaminants from entering the interior of the bearing and extend service life.
Mechanical bearings are used in almost all mechanical equipment, including:
Industrial equipment: such as motors, pumps, fans, conveyors, etc.
Automobile: such as wheel hubs, gearboxes, engines, etc.
Aerospace: such as aircraft engines, satellite dishes, etc.
Household appliances: such as washing machines, air conditioners, vacuum cleaners, etc.
Precision instruments: such as machine tools, measuring equipment, etc.
Selection points: according to the type of load, rotational speed, working environment, precision requirements and other factors to choose the right type of bearing and specifications.
Maintenance suggestions: Regular lubrication, cleaning and inspection, timely replacement of damaged bearings to ensure the normal operation of the equipment.
Mechanical bearings are vital parts in mechanical equipment, and their performance directly affects the efficiency, precision and life of the equipment. Through reasonable selection, correct installation and regular maintenance, the performance of mechanical bearings can be fully utilized to provide reliable support for all kinds of mechanical equipment.
