R77 RF77 Helical Gear Speed Reducers RX77 RXF77 Helical Coaxial Electric Gearmotor

Product Description

R77 RF77 Helical Gear Speed Reducers with motor power 0.37kw, 0.55kw, 0.75kw, 1.1kw, 1.5kw, 2.2kw, 3kw, 4kw, 5.5kw, 7.5kw and 11kw. Transmission gear reduction ratios 5.21 to 195.24. The inline helical gearboxes and gearmotors combine high efficiency, flexible design, and a wide range of ratios with maximum reliability in a wide variety of applications and industries. The helical gear units offer an optimum ratio between torque output and installation space. The coaxial helical gearmotors are foot mounted, B5 flange mounted, B14 small flange mounted, with extended output bearing hub for agitator. helical gear units with solid output shaft, Input and output shafts are parallel to each other. 

RX77 RXF77 Helical Coaxial Electric Gearmotor is for high output speeds, torque range up to 215Nm. Input power rating 1.1kw, 1.5kw, 2.2kw, 3kw, 4kw, 5.5kw, 7.5kw and 11kw. Transmission gear reduction ratios 1.42 to 8. Transmission gear reduction ratios 1.4 to 6.07. Single-stage helical gearmotors provide high output speeds, the exclusively single-stage gear units offer compact solutions for your system design. It is a combination of performance and space requirements with 6 sizes in the range to cover many applications where a small ratio reduction is required for your driven piece of equipment. These single-stage helical gearmotors are often found driving conveyors, helical rotor pumps, crane travel drives and many more applications.
