For inIn the process of mass production of SWC universal coupling, if there is a problem with the processing of the flange fork head, the fork head is a cast steel part, and each outer circle and flange end face need to be processed. When turning, the clamping method There is no problem with the fork head of the flange end car, but when turning the flange of the car, there is no way to install it. The four-jaw single-action chuck of the lathe can only be hard with two jaws and cannot be clamped. Consider the welding process jaws. Due to the large quantity, It's too wasteful and it's not easy to design tooling. In this case, we came up with a simple and easy way.Stack the forks in a staggered manner to ensure that the gaps of the forks are equal, and after the basic alignment is not deviated, spot weld the 4 welding points into a whole.In this way, the flanges at both ends can be clamped separately, and each machined surface can be turned into a machine.
The universal coupling will have the movable connection part is not very flexible and rusty after a long time of use, which is beneficial to the production efficiency.Universal couplingA certain impact will cause the production to be relatively low, so it is necessary to add lubricant to the universal coupling to ensure that the universal coupling can operate normally when in use.
However, when adding lubricant to universal joints, some workers who do not understand will use butter as a lubricant, but butter does not play a role in lubrication.The main reason why butter cannot be used as a lubricant is that butter does not have very good fluidity at room temperature. The roller needle can only be rotated in place during work, which cannot affect the universal coupling. To any role.
So which one do you need to choose when adding lubricant to the universal coupling?The recommendation made by the editor here is that gear oil should be added to the universal coupling.
Before aligning the universal coupling, it needs to be measured and calculated, and dividedUniversal couplingOnly by analyzing the deviations can the correction work be completed better.Below, a brief introduction to common measurement methods.
1. Use a square and feeler gauge to measure the radial deviation on the outer circle of the universal coupling, and then use the feeler gauge to measure the axial gap deviation between the two halves of the coupling. Through analysis and adjustment, Achieve centering.
2. Use the center card and feeler gauge to measure. Since the center card does not have a unified specification, you need to make it yourself.It can measure the radial clearance and axial clearance of the universal joint at the same time, with simple operation and high measurement accuracy.
3. The dial indicator measurement method is to install a special fixture on the semi-coupling as a reference, and then use the dial indicator to measure the deviation value of the clearance gap and the axial clearance.This method can greatly improve the accuracy of measurement.
The above are a few commonly used alignment methods, I hope it will be helpful to everyone.
According to the coupling manufacturer’sUniversal couplingShao, they need to name each coupling after the coupling is produced.When naming the coupling, it is not just a random name, but there is a certain principle. They need to name the coupling according to this principle, so that the user can understand the performance characteristics of the coupling by the name. .
The name of the coupling needs to be scientific and accurate when naming it, and the name of the coupling is required to be short and easy to remember by the user when naming it. It will be used next time. At that time, I can quickly get a general familiarity with the name and performance of the coupling.When naming the coupling based on the structural characteristics of the coupling, it is necessary to distinguish it from similar couplings. The key structural characteristics should still be reflected in the naming of the product.Some coupling manufacturers like to follow the coupling parts
