The bearing is around us everywhere in nowadays life.
Cars running in the morning lights, hoods immersed in the aroma of food, hairdryers bathed in the fragrance of shampoo... All this is closely related to bearings, which are called "food for machinery industry".
What is the bearing?
Bearing is a kind of component in contemporary machinery. Is widely used in the machinery industry, with strict requirements of accessories and basic parts, is a variety of mechanical rotation axis or movable parts of the supporting elements, but also rely on the rolling of the rolling body to achieve the host rotation of the supporting elements.
Bearings are usually composed of inner ring, outer ring, rolling body, cage, and grease.
The inner ring usually fits closely with the shaft and rotates with it. The outer ring is usually matched with the bearing seat hole or the shell of mechanical parts to support. But in some applications, there are also outer ring rotation, inner ring fixed, or both inner and outer ring rotation.
With roller cages evenly arranged between the inner ring and outer ring. Its shape size and quantity directly affect the bearing capacity and performance. Cage will even separate, roller guide roller movement in the right orbit, internal load distribution, and improve the bearing lubrication performance. Grease is used in the friction parts of machinery for lubrication and sealing. It is also used on metal surfaces to fill gaps and prevent rust.
In order to make the machine run smoothly, what role do bearings play?
First, bearings can reduce friction and make rotation smoother. The rotating shaft and support part will be friction. Bearing is used in rotating "axis" and support between parts. The bearing can reduce friction, rotate more smoothly, reduce energy consumption. This is bearing the biggest role. Second, protect the rotation support part so that the "axis" of rotation is kept in the correct position. Between rotating "axis" and support parts will suffer a great force. The bearing can prevent damage of revolving support part due to the force, spin "axis" in the right place.
Bearing in widespread use in life has a lot of bearings. With the continuous development of mechanical technology, more can adapt to the harsh environment of the special new type of bearing will be constantly develop applied to our daily life in the future. The bearing will continue to develop and progress, for our life to continue to "operate"!
