Helical gearbox speed reducer:

1.It has solid shaft output, hollow shaft output and contract disk hollow shaft output,which can be installed horizontally , vertically . It is made of high strength quality alloy steel through quenching and possesses high efficiency and long life gear .Othermore, it can bear large axial and radial load. Features is low in run noise, high in reliability, compact and so on.
2.The housing of one size can realize parallel shaft,right-angle shaft modes and horizontal,vertical mounting modes.Variety of components is reducible, the number of reducer's mode is augmentable.
3.Sound-absorbable structure, lager surface, big fan reduce temperature and noise, advanced grinding process of cylindrical gear and bevel gear improve stability and transmit power more efficeintly.
4.Input mode : motor connected flange ,shaft input.
 Output mode: solid shaft with flat key, hollow shaft with flat key, hollow shaft with shrink disk,  hollow or solid shaft with involute splines , solid shaft with flange.
5.Mounting mode: Foot-mounted, flange-mounted, swing base-mounted, torque-arm-mounted.
H.B. (P.V.)series include sizes 3-26, number of stages is 1-4,ratio is 1.25-450. Combining with CR,S and K series, ratio will be higher.
