Product Description

Product Description

KM KB Series helical gear units has more than 4 types, power 0.12-4kw, ratio 7.73-302.5, torque max 100-500NM, Modulaw and multistructure can meet the demands of various conditions.

(1) Ground-hardened helical gears.
(2) Modularity, can be combined in many forms
(3) Made of high-quality aluminum alloy, light in weight and nonrusting
(4)Large in output torque, high efficiencym energy saving and environmental protection
(5) The mounting dimension of SKM series are compatible with SMRV series worm gear unit
(A part of SMRV050 dimensions are different from SKM28)
(6) The mounting dimension of SKB series are compatible with W series worm gear unit.

Features&Specification
KM28B~KM58B:2-Stage hypoid helical gear units. Speed ratio range 7.48~60.5

KM28C~KM58C:3-Stage hypoid helical gear units. Speed ratio range:4918~302.5

One of the features of the hypoid gear speed reducer is that the shafts intersect at two mutually parallel
planes,providing greater torque in the same construction space than an ordinary helical gear reducer. And its strength is much higher than that of worm gear reducer.
 

1.Omnidirectional mounting

2.Housing made of high-quality aluminum alloydie-casting,light weight good rust resistance

3.Low back clearance

4.Smooth transmission and low noise
