Electric spindleThe various components in are closely connected, and if one of them is damaged, it will affect the operation of the entire electric spindle. Therefore, in order to ensure the normal operation and efficiency of the electric spindle, if some components are found to be damaged during daily inspections, even if not all are damaged, they should be replaced in a timely manner. So, the correct disassembly and installation methods are crucial:

1. Remove the front and rear end caps and nuts of the electric spindle.

2. Push back the electric spindle, rear bearing seat, bearings, and other accessories from the front end of the shaft.

3. Select the appropriate electric spindle bearings and gaskets to choose the matched electric spindle bearings, and install them according to the V-shaped markings on the outer diameter of the bearings. The gasket used with the paired electric spindle bearing should also be of appropriate size. If it is not suitable, one of the two sets of bearings will have a small load and the other set will have an excessive load, resulting in uneven load-bearing capacity of the electric spindle, which will generate heat and seriously affect its service life.

4. Clean the bearings by tilting the outer sleeve downwards (or the inner sleeve upwards) and rotating it for cleaning (in clean gasoline). The bearings should be cleaned at least twice. After cleaning the bearings, ensure that the upper and lower positions of the bearings are not misaligned.

5. Before installing the bearings, lubricate the bearings, inner holes of the shaft sleeve, and the main shaft with engine oil. This is to facilitate installation and ensure the lubrication of the bearings during the initial start-up of the electric spindle.

6. Clean other parts on the shaft, and the bearings should be naturally dried after cleaning. It is forbidden to dry them with high-pressure gas.

7. First, install the rear bearing, tighten the nut, and fix the spring on the bearing seat with butter. The spring cover should not be placed in the wrong position.

8. Assemble the front end bearing and secure the front end cover with a pre tightened bearing sleeve. (Special sleeves should be used for assembling bearings, and the sleeves should be machined with nylon rods. The shape is as follows: D is smaller than the outer diameter of the bearing, and D is larger than the inner diameter of the bearing.)

9. Tighten the front nut, install the front and rear end caps, and pay attention to the position of the air inlet when installing the rear end cap. The sealing rings of the air inlet, water inlet, and water outlet holes should be intact and placed correctly.

10. After installing the electric spindle, check if it is installed in place (using a wrench to push the spindle forward, it will move forward and immediately bounce back when released).
