Some companies are usingCardan shaftWhen I discovered that its vibration was relatively large, the relevant personnel did not know why this situation occurred. Therefore, I want to know what is the cause of its large vibration. Today, we will focus on its causes and solutions. Do understand.
Cardan shaftCauses of large vibration
The reason for the large vibration is related to the balance of the equipment itself. If the balance is abnormal, the natural vibration will be relatively large. On the contrary, its vibration will be much smaller.
How to determine the balance of cardan shaft
1, The balance test must be done before leaving the factory. Only after the test can the product be delivered, and then according to its weight, speed and balance level to see the allowable range of its imbalance, and then perform on-site simulation through related equipment. Look at its speed and unbalance, if it is not within the allowable range, further adjustments must be made, otherwise, the goods can be received.
2, Actually, there are two ways to balance the universal joint shaft, one is to increase the weight, and the other is to remove the weight. In most cases, it is selected to increase the weight, which means welding on the outside of the fork to help achieve the balance effect. , This suitable weight is200If it’s a lighter cardan shaft, for example20If it’s less than a catty, then you only need to do the de-duplication.
3, To be rightCardan shaftCarry out regular maintenance. The maintenance includes not only the daily lubrication of the bearings and spline pairs, but also the three-month return to the factory and the dynamic balance test, etc., so as to ensure the entire equipment The service life of the shaft can be increased while ensuring the working efficiency of the cardan shaft.
