Diesel portable air compressor and electric portable air compressor drive mechanism

　　Gear transmission and coupling transmission, the combination of high efficiency, safe and reliable, long life.

　　Helical gear transmission compensation for 30% of the axial thrust, further extend the service life of the screw

　　Diesel portable air compressor and electric portable air compressor and screw host flange connection, make sure drive system in a permanent.

　　Elastomer abrasion resistance, oil resistance, anti-aging, good internal buffer effect, reduces the starting torque, driving more smoothly.
