Disassembly Method Of Nsk Bearing

Disassembly Method Of Nsk Bearing

The disassembly of NSK bearing shall be carried out with the same care as the installation. Pay attention not to damage NSK Bearings and parts, especially the disassembly of interference fit NSK Bearings, which is difficult to operate. Therefore, in the design stage, it is necessary to consider the convenience of disassembly in advance, and it is also very important to design and manufacture disassembly tools according to needs.

During disassembly, the disassembly method and sequence shall be studied according to the drawings,Disassembly Method Of Nsk Bearing  and the matching conditions of NSK Bearings shall be investigated, so as to ensure the safe disassembly operation.

1. Removal of outer ring

Remove the outer ring of the interference fit. Set several outer ring extrusion screws on the circumference of the shell in advance. Tighten the screws equally while removing. These screw holes are usually covered with blind plugs, Disassembly Method Of Nsk Bearing tapered roller NSK Bearings and other separated NSK Bearings. Several cuts are set on the housing shoulder, and the cushion block is used to disassemble with a press or gently tap.

Disassembly Method Of Nsk Bearing

2. Disassembly of cylindrical bore NSK bearing

The inner ring can be easily removed by pressure machinery. At this time, pay attention to make the inner ring bear its pulling force. The inner ring of large Disassembly Method Of Nsk Bearing NSK bearing is disassembled by oil pressure method. Oil pressure is applied through the oil hole arranged on the shaft to make it easy to pull out. The NSK bearing with large width is disassembled by the combination of oil pressure method and drawing fixture. The inner ring of Nu and NJ cylindrical roller NSK Bearings can be removed by induction heating. It is a method of drawing after heating part in a short time to expand the inner ring.

3. Disassembly of tapered NSK bearing

Disassemble the relatively small NSK bearing with fixed sleeve, support the inner ring with the stop fastened on the shaft, Disassembly Method Of Nsk Bearing turn the nut back several times, and knock it with a hammer with a cushion block. For large NSK bearing, it is easier to disassemble it by oil pressure. Pressurize and send oil in the oil hole on the taper hole shaft to expand the inner ring and disassemble the NSK bearing. During operation, NSK bearing may come out suddenly. It is better to use the nut as a stop.

Water lubricated bearings

are divided into phenol bearings, rubber bearings, ceramic bearings, graphite bearings, Disassembly Method Of Nsk Bearing PTFE and other polymer bearings. The bearing is used directly in water without any sealing device. The bearing is lubricated by water and does not need lubricating oil or grease, eliminating the harm of water pollution. Bearings are often used in flowing water, which can effectively control the bearing temperature rise, so as to have long service life, safety and reliability.

Structurally, it is suitable for horizontal axis, vertical axis and inclined axis. It is mainly used for large industrial water pumps, power plants, nuclear power plants, ships, Disassembly Method Of Nsk Bearing water turbines, wind power generation, petrochemical industry, light chemical and food machinery, sewage treatment, waterworks, water conservancy pump stations, mining machinery and engineering machinery, valves, mixers and other fluid machinery.

Working principle of water lubricated bearing:

Bearings with water as lubricant are generally sliding bearings. Babbitt alloy used in early water lubricated bearings has long been used in the field of ships, Disassembly Method Of Nsk Bearing because water can provide hydrodynamic film under certain conditions. Water lubricated bearings are based on self-lubricating materials and combined with the lubricity of water under certain conditions, so as to be used in hydropower stations and other fields.

Water does not have the same high viscosity and lubricity as the recognized lubricant petroleum. Water does have limited viscosity and density, so it can provide hydrodynamic membrane. Disassembly Method Of Nsk Bearing The research and development of superior water lubricated bearings will be based on materials and design, which should have good self sliding and excellent friction resistance.
