Universal Joint Bearing

Universal joint bearing, refers to the use of ball not achieve coaxial transmission of mechanical structure, is a very important auto bearing parts.Universal joint and combination of transmission, known as the universal joint transmission device. The classification of the universal joint bearing: section of constant speed universal thrust ball bearing, patterned constant speed universal joint, ball cage universal joint, three pin shaft universal bearing section, double coupling type universal joint factory. In automotive transmission system and other systems, in order to achieve some axis intersection or changing the relative position between the rotating shaft power transfer, must adopt universal transmission device.2 - the shaft.Universal transmission device generally consists of universal joint and rolling mill bearing shaft, sometimes have intermediate support, mainly used for the following position. 1 - universal joint.3 - before the drive shaft.4 - middle roller bearing full engine front between the transmission and drive axle of rear wheel drive car.When the distance between transmission and drive joint bearing bridge, transmission shaft should be divided into two or more paragraphs, and adding intermediate support.Due to the deformation of the frame will cause mutual position between axis of changes between the two driving part.Multi-axis driven car between the transfer case and drive axle or between the drive axle and drive axle is between the engine and transmission.Adopt independent suspension of the car and the differential between self-aligning ball bearing.Between steering wheel drive axle differential and linear motion bearings and the power output of cars are in the steering mechanism. Universal joint bearing linear bearing in the vertical position, the working principle of active fork and cross axis plane and vertical when the drive shaft.At this point, take the initiative to the fork and cross axis and cross axis connection point and driven fork points at the special bearing axis in the plane linear velocity is equal.Driven fork to cross shaft speed of the plane projection. Because when taking the independent suspension thrust roller bearing frame, the conditions for a hard to meet, the transmission is not the main reducer relative position changing, only do not constant speed as small as possible.10 words shaft universal joint is not uniform. Refers to the driven shaft angular velocity is not uniform in the week, the fast when slow when the driven shaft, drive shaft to type equiangular rotation speed, namely single cross shaft universal joint in the transmission Angle is not constant.The first universal joint Angle between the two shaft angular contact ball bearing and the second two of universal joint shaft Angle between equal.Double cross shaft universal joint between two axis transmission output shaft and input shaft of drive axle of the condition of constant speed drive. Take the initiative to a fork in a horizontal position, wheel bearings and cross axis plane and vertical when the driven shaft. Active fork to cross shaft speed of the plane projection.The first universal joint bearing driven fork and the second active fork at the same level of the universal joint.Master-slave Angle speed of shaft bearing system.The two shaft Angle, the greater the speed, the greater the transmission shaft of non uniform.
