What factors affect cardan shaft performance?

Many friends know that a universal coupling is used to connect two axes of two different mechanisms! The structure of the universal coupling is very many, such as: cross shaft type, ball pin type, ball fork type, three-fork rod type and so on. Do you know what factors affect the performance of the cardan shaft? Let's take a look.

What factors affect cardan shaft performance?

What factors affect cardan shaft performance?

I. Materials

The materials used for making universal couplings are cast steel, aluminum alloy, etc. The different materials selected will also affect the performance of universal couplings.

2. Connection

There are many ways to connect the end face of the universal coupling, and different connection methods will have different results when transferring torque. If the connection mode is not selected properly, it is easy to break the connection key when transferring torque, resulting in equipment failure.

Iii. Correction

When the universal coupling is connected to the shaft, the universal coupling needs to be corrected. If the correction is not accurate, the performance of the universal coupling will be affected.

Universal coupling in the process of use, will encounter a variety of problems, such as abnormal vibration in operation. So, how do we solve this problem? I believe that many people have encountered this situation, below, Xiaobian to analyze this problem in detail, so that we can better cope with, and take effective measures to solve the problem.

The main reasons for the vibration of universal coupling are as follows:

1. The balance sheet or component of the universal coupling is not compensated for dynamic balance.

2, during the assembly process, the two couplings are not on the same plane.

3, the universal coupling bending or shaft tube sag problem, destroy the dynamic balance.

4. The connection bolt of the normal universal coupling orchid plate of the universal coupling is loose, causing the Angle to skew.

5, spline shaft and sleeve fork wear is too large, or the gap is too large.

Take measures to:

1. Check whether the universal coupling is dented, whether the balance sheet is lost, etc., and re-weld.

2. Tighten the bolts of the flange.

3. Reinstall the universal coupling correctly.

Universal coupling according to the structure type, can be divided into many types, such as cross shaft type, ball fork type, ball pin type, three-pin type, ball cage type, hinge type, etc., of which the cross shaft type is the most commonly used a universal coupling, followed by the ball cage type universal coupling. The common feature of universal couplings is that the angular compensation amount is large, and the β Angle of the two axes of different types of universal couplings is different, generally less than or equal to 5° -45 °. When choosing a universal coupling, you need to consider the problem universal coupling:

1, clear whether there is a transmission device between the prime mover and the universal coupling, if there is, to know the transmission ratio, there is no power shunt, the type of prime mover. Power, etc.

2. Consider the type of prime mover and the load category of the universal coupling.

3, consider the installation state of the universal coupling, if you need to tilt, to determine the horizontal and vertical angles.

4, consider the working conditions, different working conditions, the choice of universal coupling is also different.

5. Know the connection form and actual installation size of both ends of the universal coupling.

6. Know the speed of the universal coupling itself and determine whether it needs balance and how many levels of balance.

7, consider the installation position of the universal coupling, installation length, etc.

In the selection, it is necessary to consider step by step, determine the specifications of the universal coupling, and finally determine which structural type to choose.

The above is a brief introduction to some performance of the universal coupling that we bring to you! Hope to be able to help you have a need of friends!
