Universal Joint Kits

As a very important connection element, universal joints allow the connected parts to rotate in various directions. Joints are parts that support the transmission of rotational motion between the shafts which are not aligned with their axes.

Functions of Universal Joints

Universal joints provide the connection between the gearbox output shaft and the driveshaft. They are placed at both ends of the driveshaft depending on the power transmission system of the vehicle. Thus, the joint provides support to counter the height difference (with respect to the ground) between the output shaft and the rear axle which occurs due to the road conditions, and it is an important part to help the transmission of rotational power between the shafts in different axes. Universal joints are classified into different types according to their areas of use or their structure. The most common among them are cross-type joints. They consist of needle rollers. These are positioned inside the bearing cap of the joint which connects the joint with the driveshaft yokes. The rollers engage tightly around the trunnions of the joint. Then, they are held by a snap ring for each trunnion at their engagement point. Thanks to this layout, the joint and the driveshaft yokes are put in a position so that they can perform a compound movement.

Lubrication of Universal Joints

One of the most important factors for a joint is lubrication. They have to be lubricated regularly in order to use them for a long period of time. Using a grease pump, joints can be lubricated through their grease fitting. The grease supplied from this fitting reaches the holes in the trunnion and allows the lubrication of the bearings. Thus, the most sound and ideal joint movements are achieved. It is possible to purge the seals of the joint and they should be purged while lubricating. For extensive periods of use, high quality joints should be preferred. Therefore, you should prefer working with successful and reliable companies in their field when you are purchasing universal joint kits. This would help the vehicle to move as a whole and as rigid as possible.
