A friction clutch of a cold rolling mill includes a sleeve seat, an end face gland, a clamping plate, a sprocket, a pin, a friction plate, a positioning ring, an end face nut, a retaining ring, and an elastic element. Through the example of the friction clutch of the cold rolling mill, we can learn more about how to disassemble and assemble the clutch correctly?

Give an example to analyze the characteristics of the clutch.

A friction clutch of a cold rolling mill includes a sleeve seat, an end face gland, a clamping plate, a sprocket, a pin, a friction plate, a positioning ring, an end face nut, and a retaining ring. Features of this clutch include:

The elastic element sleeve seat is installed on the top of the motor shaft

The sprocket is oriented and installed on the gear sleeve, the friction plate is installed on both sides, and the positioning ring is installed in the inner hole

The clamping piece is installed on the outside of the sprocket

The end face gland is installed on the outside of the clamping piece, and the pin is installed between the two

The end nut is fixed on the end gland and sleeved on the top of the pin

The elastic element is installed on the pin; the retaining ring is installed on the journal of the sleeve seat

 

In the course of use, we all hope that the clutch will be thermally cycled as much as possible without overheating it, and the power applied is minimal. The clutch disc has high points and low points on the friction material. I want to reduce the high points and embed the friction material in the pressure plate and flywheel to create a smooth surface on the disc. If you want to get the most benefit from the clutch and extend the use time as much as possible, you need to disassemble it appropriately.

 

Problems when disassembling the clutch.

Now, if you are impatient and decide to make the clutch rough before installing it correctly, you may have some very bad consequences, the worst of which is to polish the disc.

 

When glazing the disc, the friction material is basically polished to be smooth, because excessive force is applied to the clutch before it is inserted correctly. Once the clutch disc is glazed, it loses friction. It's a lot like sanding off all the sand, or the tire has all the tread off. In addition, since the surface is very smooth, the grip is not very good. Once the friction on the disc disappears, it cannot be restored. If you want the clutch to work normally again, you must replace the disc.

 

How to disassemble and assemble the clutch correctly?

Before installing the clutch friction plate, please compress the pressure plate and flywheel. If you want to use a new flywheel or pressure plate, you should remove all clutch material from the previous brake disk, and remove any chemicals or lubricants in the worst case.

 

The insertion of the clutch is easy, it is just a waste of time. The theory behind it is that you want to immediately transfer some of the friction material of the clutch disc to the pressure plate and flywheel. Doing so will greatly increase the clamping force. What you don't need to do will transfer the adhesive in the clutch plate to the pressure plate and flywheel, which will greatly reduce the clamping force.

 

When new adhesives are heated too quickly, they will "seep" from the clutch disc. If the adhesive oozes out, they will "gloss" the clutch and leave a layer, which is not always the case even on the pressure plate and flywheel.
