How to improve the capacity of wire rope hoist gear?

Wire rope hoist gear is an indispensable accessory, one bite each gear parts work with each other in order to achieve the wire rope  manual hoist  lifting, running gear directly affect the carrying capacity of hoists, the following analysis should be how to improve the capacity of wire rope hoist gear?

Electric wire rope hoist gear can be 40Cr, 40MnB material, gear surface to be treated by quenching or nitrides, at present, some domestic enterprises also used 20CrMnTi material, this material gear bending strength and contact strength is ideal.
Traditional low precision gear machining,wire rope winch carburizing quenching deformation difficult to control, after the sequence nor grinding process, it is inevitable there is gear noise, low efficiency. New materials and heat treatment method has many domestic manufacturers to promote.
Wire rope hoists used in hardened and hardened gear meshing pairs, using high-level gear shaving process, election gear helix angle of about 12 ~,load chain which are geared to improve stability and effective way. Gear box, cover design should be conducive to the absorption of noise and vibration damping, transmission bearings should improve accuracy levels.
