Application and application of self-aligning ball bearings
The classification of rolling bearing in rolling bearing structure: 1. types of classification (1) according to the direction of the load bearing can withstand or nominal contact angle is different, is divided into: 1) - - radial bearing is mainly used for rolling bearings under radial load, the nominal contact angle from 0 to 45. According to the nominal contact angle is different, is divided into: radial contact bearings - - nominal contact angle of 0 of the centripetal bearings: radial contact bearings - --- nominal contact angle greater than 0 to 45 of the radial bearing. 2) thrust bearings --- rolling bearings, which are mainly used to bear axial loads, have nominal contact angles greater than 45 to 90. According to the nominal contact angle is divided into: axial contact bearings - --- nominal contact angle of 90 thrust bearings: thrust angle contact bearings - --- nominal contact angle greater than 45, but less than 90 of thrust bearings.
(2) bearings according to the kind of rolling, divided into: 1) ball bearings - --- rolling ball for the ball: 2) roller bearings - --- rolling bodies for the roller. According to the type of roller bearing roller, cylindrical roller bearings can be divided into: - - rolling body is cylindrical roller bearing, cylindrical roller length and diameter ratio is less than or equal to 3; needle bearings - rolling body is needle bearing, needle length and diameter ratio greater than 3, but the diameter is less than or equal to 5mm; cone roller bearings - - rolling bearings tapered roller; roller bearings - spherical roller bearing rolling body is. (3) bearing according to the work can adjust the heart, is divided into: 1) - - self-aligning bearing raceway is spherical shape, can adapt to the two roll bearing road angular deviation between the axis lines and angular movement; 2) non aligningbearings (rigid bearing) - - impedance raceway axis line angle offset bearing. (4) bearing divided according to the number of rolling body: 1) - - single row bearings with a rolling body of the bearing; 2) - - double row bearings with two rows of rolling bearings; 3), with more than two columns bearing rolling body bearing, such as three or four column bearing.
