Design features

?? structure features
-high quality die casting aluminum alloy housing, suitable for universal mounting.
-heat sink design for cooling provides great surface area and higher thermal capacity than the casting iron housings.
-8 sizes from 030 to 130 cover the power scope from 7.5w to 60kw.
-larger speed ratio range. Each single frame size has 12 ratios from 5:1 to 100:1.
-hardened worm with fine grinding has the features of higher efficiency and big output torque.
-low noise and stably running, can adapt long term work condition in terrible environments.
-light weight, high mechanical strength.
-modularization combination pcrw & drw extend the ration of rw reducers from i=5:1 to 3200:1.

?? main materials
-housings: Die-cast aluminum alloy (frame size: 030 up to 090); Casting iron (frame size: 110 to 130)
-worm: 20cr steel, carburization and nitriding treatment (keep the hardness of tooth surface be hrc60 and the thickness of harden layer over 0. 5mm after precise grinded).
-worm wheel: Special wearable bronze and nickel bronze alloy

?? paint
-aluminum alloy housing:
??shot blasting and special antiseptic treatment on the aluminum alloy surface
?? after phosphating, coated with blue ral5010 baking finished.

-cast-iron housing: Painted with ral5010 blue baking finished.
