Helical Speed Reducer - R Series
-Have adpoted modularization design, large speed range and rational and fine assignment
-14 sizes from 07-167, with power scope from 0.09kw to 160kw
-The housing design is suitable for universal mounting.
-The speed ration covers from 1.3 to 289.74, so the customer can choose the one as they need.
-Gear wheel after high fine grinding makes stably running, low noise and the efficiency between two near stages reaching to 98%.
-DRC designed for particular low speed occasions extends the ration of RC to 27000.

MAIN MATERIALS
-Housing: Die cast aluminum alloy (frame size: 07-27); Cast iron (frame size: 37-167)
-Gear wheel: 20cr steel, carburization and nitrating treatment (the hardness of tooth is HRC60 and the thickness of harden layer is over 0.5mm after fine grinding)
-Plain key: 45 steel and the hardness of surface is HRC50.

Arm type installation, and output through hollow or solid shaft.
