The working principle of universal bearing When the active fork is in the vertical position of the linear bearing, and the cross shaft plane is perpendicular to the active shaft. At this time, the linear velocities of the connecting point of the driving fork and the cross shaft and the connecting point of the driven fork and the cross shaft on the axis plane of the cross special bearing are equal. The velocity projection of the driven fork onto the cross axis plane. Because the condition 1 is difficult to meet when the non-independently suspended thrust roller bearing frame is used, the relative position of the transmission and the main reducer is constantly changing, and the unequal speed can only be as small as possible.
The double cross-shaft universal joint realizes the condition of constant speed transmission between the output shaft of the transmission between the two shafts and the input shaft of the drive axle. When the driving fork is in the horizontal position and the plane of the cross turntable bearing axis is perpendicular to the driven shaft. The driving fork is directed The velocity projection of the cross axis plane. The bearing driven fork of the first universal joint is in the same plane as the driving fork of the second universal joint. The angular speed of the driving and driven shaft is related to the bearing system. The greater the angle of intersection between the two shafts, the greater the speed, and the worse the unequal speed of the drive shaft.
