Electric hoist gears numerous scholarship

Electric  lift hoist  gear is a very important accessory, it affects the gear engagement between the various components and thus the entire device associated with, do not look small electric hoist gear volume not much, but it contains a large number of missing knowledge, its level, material and the teeth are related to the life of electric hoist, the following details for you:
1, the electric Wire rope hoist  for the general working machine, the speed is not high, you can choose seven precision.
2, the gear material selection, in general, small gear: 40Cr, quenching, HBS1 = 330 contact fatigue strength limit: MPaH10001lim = σ bending fatigue strength limit: MPaFE7201 = σ gear: 40Cr, quenching, HBS2 = 260 contact fatigue strength limit: MPaH8202lim = σ bending fatigue strength limit: MPaFE6602 = σ
3, electric hoist gear, a small number of teeth Z1 = 14, a large gear Z2 = i · Z1 = 3.93 × 14 = 55.
4, in order to improve the entire rope hoist  the smooth transmission and drive strength, suggested the use of helical gears.
Accessories with small but it affects the whole, but also to remind the majority of new and old customers to buy electric hoists and other equipment must not neglect the inspection of small parts.
