Deep Groove Ball Bearings Synthesized by two parts
Characteristics of deep groove ball bearing structure
Deep groove ball bearing inner and outer ring raceway are arc-shaped deep groove, channel radius slightly larger than the ball radius. Mainly used to bear the radial load, but also can withstand a certain axial load. When the radial clearance of the bearing increases, with angular contact ball bearing function, can withstand greater axial load, but also for high-speed rotation. Bearings in the shell hole and the axis of the relative tilt 8 '~ 16', still can work, but affect its service life. In the case of high speed and should not be used in the case of thrust ball bearings can be used to bear the kind of bearing pure axial load.
Deep groove ball bearings generally use a two-piece steel plate stamping cage, but large or high-speed bearings are used solid cage, the cage with the same as the stamping cage, high-speed deep groove ball bearings to maintain The frame is usually guided by an inner or outer rim.
Compared with other types of bearings of the same type, deep groove ball bearing friction coefficient is small, vibration and noise are also low, high speed limit, high precision, is the preferred type of bearing selection. However, the kind of bearing impatient impact, not suited to bear the heavy load.
Deep groove ball bearing structure is simple, easy to use, is the largest production volume, the most widely used a class of bearings. Widely used in automobiles, home appliances, machine tools, motors, pumps, agricultural machinery, textile machinery, and many other areas. Its output accounted for more than 70% of the total output of bearings, is China's highest yield, the most common use of the cheapest price of a class of bearings.
Deep groove ball bearings are the most common type of rolling bearings. The basic deep groove ball bearings consist of an outer ring, an inner ring, a set of steel balls and a set of retainers. Deep groove ball bearing types are single and double row two, single row deep groove ball bearing type code is 6, double row deep groove ball bearing code 4. Its structure is simple, easy to use, is the most common production, the most widely used a class of bearings.
Deep groove ball bearings are mainly subjected to radial loads and can also bear both radial and axial loads. When it is only subjected to radial loads, the contact angle is zero. When the deep groove ball bearings with a large radial clearance, with angular contact bearing performance, can withstand greater axial load, deep groove ball bearing friction coefficient is very small, the limit speed is also high.
Deep groove ball bearing structure is simple, compared with other types easy to achieve high manufacturing accuracy, so easy to become a series of mass production, manufacturing costs are low, the use of very common. Deep groove ball bearings in addition to the basic type, there are a variety of variant structure, such as: with dust cover deep groove ball bearings, rubber seals with deep groove ball bearings, groove groove groove ball bearings, Ball gap of the large load capacity of deep groove ball bearings, double row deep groove ball bearings
Deep groove ball bearings can be used for gearboxes, instrumentation, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, construction machinery, yo-yo.
