Talk about what tests the universal joint shaft needs to do before leaving the factory

From the current point of view, universal couplings can be divided into two categories: precision and large torque. Moreover, as a whole, they have a wide range of applications and can be used in machine tools, automobiles, precision machinery and Heavy machinery and other industries and fields. In terms of its composition, two fork-shaped parts and one cross-shaped part are both very important components.

It is necessary to do its daily maintenance work, because this work is related to whether the product can be used normally and whether it can have a good use effect, and it is also related to the service life of the product, so the above conclusion and specific The requirements must be strictly enforced, and there should be no sloppy and slackness, so as not to affect the normal use of the product.

Cardan shaft is a rotating body with high speed and less support, so its dynamic balance is very important. Generally, a dynamic balance test must be carried out before leaving the factory, and adjustments have been made on the balancing machine.

It is composed of a shaft tube, a telescopic sleeve and a universal joint. The telescopic sleeve can automatically adjust the distance between the transmission and the drive axle. The universal joint keeps the change of the angle between the output shaft of the transmission and the input shaft of the drive axle, and realizes the constant angular speed transmission of the two shafts.

The cardan shaft is composed of three major parts, namely the outer ball cage, the intermediate shaft, and the inner ball cage. The splines at both ends are respectively used to connect the hub and the differential, and the torque output by the engine passes through the differential, the inner ball cage, the intermediate shaft, and the outer ball cage to the hub. It is divided into one on the left and one on the left, and the length of the left and right drive shafts is determined according to the arrangement position of the engine. In the traditional structure of the transmission shaft telescopic sleeve, the spline sleeve and the flange fork are welded together, and the spline shaft is welded to the transmission shaft tube. The new type changes the traditional structure. The spline sleeve and the transmission shaft tube are welded into one body, and the spline shaft and the flange fork are made into one body.
