Notes

Gearbox

The output shaft diameter of gearbox 1#,2#,3# are 18,22,28mm separately.the material of gearbox is alum alloy.4#,5#,6# are 32,40,50 respectively.Gearbox is made of cast iron.

Gear piece

The material 40Cr mixes to HB280,then dealed with high frequency quencher HRC50.Gear should be processed by milling with high precision.The class is 6.

Gear shaft

The material 20CrMnTi will be changed into HRC60 through processing of cementite quencher.Gear shaft will be processed with gear hobbing.Precision class is 6.

Motor shaft

The material 40Cr mixes to HB280,then dealed with high frequency quencher HRC54.Finally,gear is cut for the second.motor shaft will be processed with gear hobbing.Precision class is 5-6.

Ball bearing

We adopt tight bearing with high precision,to make sure longterm running lift.

Oil seal

Gear shaft gives priorith to enduring high temp,avoiding oil infiltration.

Terminal box

Two type.one is al alloy,which equips good capability of waterproof and dustproof.Protection grade is IP54.The other is steel case with deft structure.Protection grade is IP20.
