Helical Gear Reduction Motor
GR series helical gear reduction motor is suitable for operating under the ambient temperature of -10℃~+40℃,and the alititude can reach 1000 meters. Our Helical hypoid gear motors Can be used for positive and negative rotation,no industry restrictions.
Technical parameters
- Output speed(r/min):0.04-522
- Output torque(N.m):top to 5000
- Power(KW):0.12-200
The input shafts and output shafts of GR series have small eccentricity. Units of GR series consist of single-stage,two-stage or three-stage helical gears.
GR series helical gear reduction motor: Foot-mounted three-stage or two-stage helical gear reducer motor
Product Features

1. Highly Modular Design: Easily compatible with various types of motors or other power inputs. The same model can be equipped with motors of varying power. Easy combination and connection between different models.
2. Gear Ratio: Finely divided and wide range. Combined helical gear reduction motors can achieve very large gear ratios, resulting in extremely low output speeds.
3. Installation Method: Installation location is unrestricted.
4. High Strength and Compact Size: The housing is made of high-strength cast iron. Gears and gear shafts undergo gas carburizing, quenching, and precision grinding processes, resulting in high load-bearing capacity per unit volume.
5. Long Service Life: Under correct selection (including the use of appropriate service factors) and normal use and maintenance, the service life of the main components of the reducer (excluding wear parts) is generally no less than 25,000 hours. Wear parts include lubricating oil, oil seals, and bearings.
6. Low noise: The main components of the reducer are precision-machined and carefully assembled and tested, resulting in low noise.
7. High efficiency: The efficiency of a single-unit gear reducer is no less than 95%, and the efficiency of a worm gear reducer can reach 89%.
8. Capable of withstanding large radial loads.
