Flange Mounted Hydraulic Helical Worm Gear Reducer With Electric Motor

S Series helical-Worm Geared Motors

Besides the routine characteristics, S Series helical-Worm Geared Motors adopts helical gear-worm wheel type to make the structure more reasonable.This series not only has higher transmission efficiency and loading capability than those of single-stage worm wheel transmission, but also reduces space.
Moreover,under the close volume, the series can obtain higher transmission ratio and is more favorable for equipment setting. The product can be combined with various reducers and variators to meet the differentrequirements.

1) Output speed: 0.3 - 145r/min
2) Output torque: up to 4,000N.m
3) Motor power: 0.18 - 22kW
4) Mounted form: foot-mounted and flange-mounted mounting

Technical data:

1 output torque:90-4000(N.m)
2 rated power:0.18-22(kw)
3 input speed:≤1500 (rpm)
4 output speed:≤146(rpm)
5 transmission ratio:≥10.27
6 series:2
7 install form:M1-M6
8 Model no. :S/SA/SF/SAF/SH/SHF(37/47/57/67/77/87/97)


1. Highly Standard Modular Designed
The products are easily connected with and driven by different types of motors or other kinds of input power.The same type geared motor can be adapted to optioned powers of motors.It is therefore easy to realize different solutions for varied requirements.
2. High strength, Compact dimension
Housings are made of high strengh cast iron. Gears and shaft gears are finished with gas carburising process and precise grouding to sequentially get high loading capacity of percertain volume.
3. Long service life
Under the condition of accurately selecting type size and the normal maintenance and use,main components(except those easily-disabled parts)can last as long as up to more than 25,000 hours.Easily-disabled parts include lubricating oil,oil seals,and bearings.
4. Low noise
All key components are finished by precisely machining,accurate assembly,and finally tested,and therefore,fairly low noise is reached.
5. High efficiency
The efficiency of gear unit can reach 95%,the efficiency of worm gear unit can reach 89%.
6.Large radial loading ability
7. Axial load ability of up to 5%of radial load

A small volume, light weight, compact structure, bearing capacity is strong
B smooth operation, little vibration, low noise, low temperature rise
C block structure, combination convenient, strong commonality
