How to remove the rear bearing of the van and how to remove it

First, use the four corner screws of the bearing seat to fix and install the center plate, the center is aligned with the centering hole of the shaft, the shaft is pushed out of the shaft by using the center, and then the bearing parts can be pulled out from the bearing seat by pulling the tool.

Bearing is an important component in contemporary machinery and equipment. It is used to determine the relative motion position of the rotating axis and other parts, and plays a supporting or guiding role. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load of the equipment during the transmission process.

According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings.

It is an important basic component of all kinds of mechanical equipment, and its accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the main engine.

In mechanical products, bearings belong to high-precision products, not only need mathematics, physics and many other disciplines of comprehensive support, but also need material science, heat treatment technology, precision machining and measurement technology, numerical control technology and effective numerical methods and powerful computer technology and many other disciplines to serve, so the bearing is a product on behalf of the national scientific and technological strength.

With the intensification of competition in the bearing manufacturing industry, mergers and acquisitions between large bearing manufacturing enterprises and capital operation are becoming more and more frequent, and domestic outstanding bearing manufacturing enterprises are paying more and more attention to the research of the industry market.

In particular, in-depth research on the industrial development environment and product buyers. Because of this, a large number of excellent domestic bearing manufacturing brands have risen rapidly and gradually become leaders in the bearing manufacturing industry!

At present, China's bearing industry is mainly facing three outstanding problems: low production concentration in the industry, low R&D and innovation capabilities, and low level of manufacturing technology.

Personally, I recommend going to a professional store I hope I can help you, if you have any questions, you can continue to ask, and I also wish you a safe drive.

Remove the tire.

There are four screws that are removed with a 12 or 13 wrench near the screw of the brake cylinder to exhaust the air, and the four screws are connected to the disc of the rear axle to install the brake cylinder, and the tire is fixed with tire screws after removing the four screws.

There is also a bearing between the half axle and the rear axle that is a little tight, one person pulls the tire with his hand, and the other person hits the tire with a sledgehammer before the half axle can be separated from the rear axle.

Remove the tires and brake drums, brake pads, and the 4 fixing screws of the lining disc, install the brake disc on the half shaft upside down, and do not screw the 2 nuts diagonally, there must be an open space, and it is very convenient to pull out the half shaft.

Go to the auto repair shop and get it for a few dozen dollars.

Remove the rear wheel, and then remove the brake drum, and you can remove the half shaft.

To replace the van generator bearings, you need to prepare tools: wrenches, screwdrivers, bearings, pliers, grease, etc. First of all, it is necessary to disassemble the Shusen Raid generator and open the housing.

Then use a screwdriver and pliers to remove the old bearings and other components. The internal parts are then cleaned and greased. Installing New Bearings:

Place the new bearing into the seat and gently adjust the position with pliers until the bearing is in the correct position. The next step is to reassemble the generator: install all the original components back on, rearrange the wiring, and check the voltage with a meter.

Finally, install it as a whole and test the performance of the generator to ensure its normal use.

Tools Ingredients: Flywheel cover tools, flywheel fixing wrenches, large adjustable wrenches, grease or anti-caking agents. Here's how:

1. Use a fly wrench to remove the rear wheel from the rear frame of the bicycle, remove the quick release lever, and pay attention to the small springs on both sides.

2. Take out the cassette flywheel cover tool dedicated to disassembly, which cannot be replaced by a wrench, as shown in the figure below.

3. Attach the flywheel cover tool to the flywheel cover so that the spline and groove are aligned.

4. Install the flywheel fixing tool so that it completely engages with the flywheel piece, and the function is to prevent the flywheel tower base from rotating.

5. Place the flywheel facing up, and use a large wrench to start unscrewing the flywheel cover tool counterclockwise.

6. Tighten the flywheel cover clockwise, and pay attention to the minimum flywheel blade not to be misplaced.

7. Carefully check whether the spacing of the flywheels is even, and then use a wrench to completely tighten the flywheel cover.

8. Use a movable wrench to tighten the flywheel cover clockwise until it cannot be screwed, and the disassembly and assembly of the rear wheel bearing of the bicycle is completed.

Note: The rear wheel of the bicycle has rolling bearings. Bicycles usually have a bead structure on the rear wheel, or they use industrial bearings directly. Both have the same principle and both belong to rolling ball bearings.

It's just that there are all the differences in the process of pretending to be old. In addition, some high-end wheels are equipped with needle roller bearings in the rear wheel tower. Needle roller bearings also belong to rolling bearings, but the object that rolls inside the former bearing is global, while the object that rolls inside the needle roller bearing is cylindrical.
