Most of electric winches utilize the planetary gear to make the reducer gear. Planetary gear has a advantage of little capacity, and relatively huge resulting reduction ratio. Moreover, a more gear contact points, a longer electric winches??￥ life. The electric winches often require to deploy in the more narrow space, and so the smaller and lighter is a better. Planetary gear are able to achieve it requirement, when also have the greater reduction ratio, and so be great.
We try to succinctly explain a internal working mechanism of the electric winches. First, a power of automotive batteries drives the electric motor. Drum of electric winches drives rotation axis, and then drive gear axis to create the strong deceleration. So a increasing torque is transferred back to drums, drum would drive the noose. Between the motor of electric winches and reducer file there is a clutch, handling through a switch. The brake unit is in a drum, when the noose tightened, the drum is automatically locked.
- Planetary gear unit of electric winches
Many electric winches are made of a composition of three planetary gear units, to be able to produce a greatest reduction ratio.
