High Speed Rotary Shaft Seals
PTFE Seal
This characteristic of high speed rotary seals are wear-resistant, self-lubricating and dustproof, suitable for this motor of electric vehicle because motor has the highest efficiency at high speed, so the sealing requirements are very different from this transmission of gasoline vehicle. Gasoline engines often run at 2,000 to 4,000 RPM, however, electric motor drives usually run at speeds up to 8 times, at 16,000 RPM in general. The key technology of electric vehicles is the direct connection of the electric shaft, electric motor, and transmission, moreover the gearbox needs high-efficiency lubrication, and the motor must be kept dry for a long time. Therefore, a highly reliable seal is required between these two components. These seals of electric vehicle are particularly required to have excellent wear resistance, self-lubricating and dry running, and dustproof functions.
The Design Details of High Speed Rotary Shaft Seals
The PTFE has excellent sliding characteristics, great electrical resistance, and non-bonding surface. It is one of the solids with the lowest friction coefficient, allowing electric vehicle seal to achieve excellent sealing and self-lubricating effects.
The lip design and material of seal are different from traditional oil seals, and the sealing performance and working life are better than traditional oil seals. The leakage of high speed rotary sealing is close to zero after testing, and the pushing lip is tightly attached to the shaft, improving the sealing effect also increases working life, so that the leakage gets close to zero and the friction is reduced by 75%.
The Application and Advantage of High Speed Rotary Seals
NIYOK high speed rotary seal is specially designed and produced for high-speed applications. Regardless of high-temperature environments, semiconductor applications, and low-friction solutions, they can be constructed with special sealing lips, therefore the sealing performance and working life are better than traditional Oil seal.
NIYOK high speed rotary seal breaks through the industry bottleneck in process technology with limit of standard tolerance and flexible application and conforms to the process and standards of ISO 9001 and IATF 16949, will provide different types of PTFE application in accordance with requirement of different industries and customers, including the use of PTFE material, and the best advice. NIYOK also can offer customized services according to customer needs and industry attributes, meanwhile co-develop with customers to meet their project and solution requirements.
Characteristic
- The lip design and material of seal are different from traditional oil seals, and the sealing performance and working life are better than traditional oil seals.
- PTFE has a self-lubricating effect, has a very low friction coefficient, is not easy to wear on the shaft surface, and has a wide applicable temperature range from -10 ~ to 200°C.
- The upper limit of PV is up to 100bar.m/s, which can be applied to vacuum, high and low temperature, corrosive environment, hard shaft surface, poor lubrication, high cycle speed, high pressure environment (applicable speed 16,000 RPM or more).
- Low pressure applications can reach 60m/s, better the material of DIN3760.
- This seal is suitable for use in electric vehicles. When the axle is rotating at high speed, it needs to be wear-resistant, self-lubricating and dustproof. The seal on the shaft makes it easier to rotate at high precision and high speed, and can extend working life.
