Cross universal coupling speed and balance level

The required connection forms and specific installation dimensions at both ends of the cross-axis universal coupling 

are required, as well as whether there are any special requirements such as installation brackets. What is the speed of 

the cross universal coupling itself and whether it needs to be dynamically balanced. Dynamic balancing is required, 

and which level of balance quality is required. During assembly, the two universal joints of the same universal joint 

coupling are not in the same plane; the cross-shaft universal joint is bent, the shaft tube is dented, the marks are not 

aligned when the drive shaft is assembled, or the cross-shaft universal coupling is The universal fork and spline shaft 

of the machine are tilted when welded to the shaft tube.

The universal joint shaft is generally composed of a universal joint, a transmission shaft and an intermediate support. 

It is mainly used to transmit torque and rotational motion between two shafts whose relative positions change from 

time to time during the work process. The transmission efficiency is high and the cross-axis universal joint has a simple 

structure. Good durability. Connect under the condition that there are angles between different centers. It is characterized 

by large load bearing, synchronous operation, no dead rotation, and the ability to withstand extremely large axial forces. 

It is small in size, compact in structure, has fully enclosed tooth groove friction surfaces for bathroom lubrication, and 

increases the number of tooth grooves to achieve corner flexibility.

Using the spherical surface to make teeth not only achieves the utilization of materials, but also improves the strength of 

the teeth and the joint surface of the alveolar. The cross-axis universal coupling is a commonly used transmission 

system accessory in the automotive industry. Its mechanical ability is very powerful and can transmit kinetic energy. The 

transmission shaft uses two non-uniform velocity universal joints. If there is a clicking sound from the bottom of the car 

when starting with the clutch released, or when accelerating or decelerating rapidly, it means that the non-speed universal 

joint joint should be replaced.

We came up with a simple and easy way to stagger and stack the fork heads together to ensure that the gaps between the 

fork heads are equal. After basically aligning them without deflection, we spot-weld the four welding points into a whole. In 

this way, the flanges at both ends can be easily clamped and each machined surface can be turned. On front-drive cars, each 

half-shaft uses two constant velocity universal joints. The universal joint close to the transaxle is the inner half-shaft universal 

joint, and the one close to the axle is the outer half-shaft universal joint.
