How to disassemble the large slewing bearing? Four ways for your reference
The turntable bearing is a large bearing with a special structure. It can withstand a comprehensive load such as a large axial load, radial load, and overturning moment. It also has a variety of functions such as support, rotation, transmission, and fixation. Applications in the seed industry or equipment are widely used. Many friends are not very familiar with how to disassemble large -scale turntable bearing.
1. Tapping and disassembling method
In many disassembly scenarios, the knocking method will be used. In short, using a copper stick or other soft metal materials less than the inner diameter of the bearing to the shaft end (if the bearings are at the end of the axis), use the hand hammer to knock on the bearing in the bearing. The circle slowly falls off. This method is simple and easy to do. The disadvantage is that it is easy to cause damage to the bearings. Therefore, you should be careful when operating. You need to pay attention to the rolling of the bearing and keeping the rack.
Second, pull out the disassembly method
This method needs to use a specialized tool to generate a uniform pull force by rotating the handle to pull out the bearings. This method is better to protect the bearing, and you need to pay attention to the following points when operating:
1. To hook the hook of the stretch to hold the inner ring of the bearings, if the accidental hook may cause excessive or damage to the bearing loosening on the outer ring.
2. To make the screw rod on the center hole of the bearing, pay close attention to the force of the bearings during the process of pulling out to avoid damaging the hooks and bearing.
3. Pay attention to prevent the hook from slipping, the corner of the bend of both feet should be less than 90 °
Third, pressure disassembly method
This method needs to use the pressure machine to press the bearing. The working process is smooth and reliable, and generally does not damage the machine and bearings. Pay attention to the effort point of the pressure machine should be on the center of the axis, and cannot be compressed. Common pressure machines are manual, mechanical or hydraulic type.
Fourth, heat treatment and disassembly method
The bearing for disassembling tightness can be performed first, and then pulled out with the help of the tension. Generally, the oil that is heated to about 100 ° C is poured on the bearing to be demolished. After the bearing ring is heated and expanded, the bearings are evenly pulled out with the help of a dedicated tape. This method should do a good job of self -protection and oil body recycling to prevent scalding; wrap the shaft body before heating, so that the bearing can not disassemble the bearings caused by heating and expansion.
The above is the specific introduction of how to disassemble the large -scale turntable bearing, I hope to help you.
