[0002] Oil-free belt air compressor is a high-efficiency, environmentally friendly, low-noise air compressor suitable for many different fields. It is very suitable for the medical, pharmaceutical and food processing industries that require high-quality compressed air. Since it does not require the use of lubricating oil, it can avoid oil pollution and odor pollution, ensuring the purity and hygiene of compressed air.

[0003] The transmission mode of oil-free belt air compressor is mainly belt drive, that is, the motor drives the compression components of the air compressor through the belt to compress the gas. Due to the aging and wear of the belt, it needs to be replaced on time.

[0004] When replacing the belt, since the distance between the transmission pulley used by the motor and the pulley that receives power for the compression component of the air compressor is fixed, when installing the belt between the two pulleys, personnel need to pull and put on the belt with great effort to complete the installation. The process may also easily cause the belt to pinch personnel's fingers.
