The principle of electric gourd? Do you need a reducer
Electric hoist works: start the hoisting motor a heavy weight lifting height is up and running again appropriate motor simplex word edge of steel beam to walk on the specified position running car driven by motor running when the car to walk on both sides of the wheel because walking speed is a little therefore run the car brake institution running car prevent weight loss when walking on the lifting mechanism set up electromagnetic brake in accordance with the pressure inside and outside dish compression principle similar to friction clutch release when using electromagnet electricity to absorb outside dish and make the inside and outside dish loosen the electric brake circuit in parallel with the hoisting motor circuit so as long as the hoisting motor startup electromagnetic brake release heavy upper and lower lifting the; When the motive is turned off, the electromagnetism brake is also the power of the power failure of the electromagnetic attraction
When the electric motor rotation drive reducer high speed shaft rotation and driving moment passed by gear wheel gear to gear reducer class through hollow shaft and spline with hollow shaft connection by spline connected to reel the pass reduction drive torque make drum rotation to make wire rope winding or off the drum and make the hook and hoisting load lifting or falling to complete the function of lifting mechanism
You need to install the speed reducer to control the speed.Action principle: the motor shaft is connected to the gearbox shaft through the rubber tyre flexible coupling
The motor that is mounted at one end of the cylinder is connected by a flexible coupling to the reduction gear on the other end of the drum. On the fan shaft at the other end of the motor, there is a cone brake. Power electric motor, the rotor shaft magnetic effect, to overcome the pressure of the spring, make its move to the left, fixed on the rotor shaft conical brake and motor end cover after the release, the rotor under the action of the spring, even the coaxial taper on the brake to the right, end cover after close contact with the electric machine, the friction torque motor stop.
The electric motor usually adopts a cone-shaped rotor motor or a magnetic circuit motor with tapered brake, which provides the driving force of the gourd lift or horizontal motion. Use a switch box with lifting and walking buttons on the lower part of the suspension cable to control the ground.
