Universal Joint Cross Bearing Manufacturer: A comprehensive guide

You may want to know about Universal joint and its functioning. Among all flexible couplings, it is stated to be among the oldest one. It is used commonly in trucks and automobiles. This joint is located at the place where there are joined two shafts at an angle for transmitting torque.

Connecting point

In a vehicle’s transmission system, output shaft is in the gearbox. But differential pinion shaft and propeller shaft are not present in a single line. Hence, universal joint is used to make connection between them. Torque transmission is permitted at a particular angle. As the vehicle moves, this angle changes constantly. It is termed as hook joint or Cardan joint.

Purpose

Differential tends to rise and fall while the vehicle moves on uneven roads. Simultaneously, propeller shaft rotates. This causes changing of angles by the propeller shaft. Universal Joint in such cases, allows propeller shaft angle to change without transmission. Connection is likely to fail if differential is connected with gearbox directly, but without this joint.

Functions

• They permit power transmission at a particular angle. Besides this, it also functions when angle is constantly changed.
• One shaft rotation is permitted on its axis with another shaft that rotates on own axis.
• Two shafts are connected with intersected axles.

Know the benefits

• Quality products produced by Universal Joint Cross Bearing Manufacturer exhibit more elastic properties when compared to knuckle joints.
• They are more affordable and simple enough to be assembled/disassembled.
• Torque transmission is supported by such joints between shafts having angular misalignment.
• Angular displacement is supported by such joints unlike other types.
• They can ensure higher torque transmission efficiency.

Know the disadvantages

• Axial misalignment is not supported.
• Such joints might cause unstable motion.
• To avoid wear and tear, it might need frequent maintenance.
• It could wear out if lubrication is not done properly and frequently.

Know the types

Constant Velocity type: This type allows driven and driving shafts tend to move around at constant velocity. The reason is that two joints acts upon same angles. Typically, such joints are used in front wheel driven (axle) vehicles. Speed variation between driven and driving shaft exhibits difficulty in steering system, thereby causing excessive tire wear.

Ball Trunnion type: This can be stated to be slip and universal joints present in the same assembly.  There is present ball type head fastened to drive shaft or propeller head’s end. Cross or pin shaft pressed through the shaft end, thereby forming ‘T’ shape. Two steel balls, in this pin are firmly fitted. Balls may axially move in direction.

Cross type: There is present a crosspiece (spider) and two Y shaped yokes. The first is attached to driven-shaft and the other with driving shaft. Four arms or trunnion is present in the cross piece connected with the yokes’ both ends. Each arm is provided with four bearings that allow yoke movement around trunnion.

Applications

Universal joints tend to differ based upon hub type and material form. They are used commonly in rear wheel drive vehicles in propeller shafts. They are used to transmit power or motion or both. A wise purchase can allow proper fitting and use. Nuhydro provides a wide variety of cardan shafts and can easily meet the needs of diverse industries. They adhere to prevailing international standards to manufacture products under professional guidance.
