What Is a Worm-Gear Winch?
JH back column winch is mainly used in the coal mine underground coal dust or explosive gas environment and other mines with an inclination angle of less than 30 °. JH back-to-column winch is instantaneous working system, not suitable for continuous working system.
JH back column winch
Right!
- JH back column winch is mainly used in the coal mine underground coal dust or explosive gas environment and other mines with an inclination angle of less than 30 °. JH back-to-column winch is instantaneous working system, not suitable for continuous working system.
- The electrical equipment of the JH back column winch has explosion-proof performance, and it must have a product with a mining product safety mark certificate within the validity period before it can be used in coal dust and gas mines. The type of the winch is a single-cylinder winding, which adopts a worm gear reducer and an open gear transmission. The winch uses a worm gear reducer, which must be installed horizontally to ensure the oil-immersed lubrication quality of the turbine worm.
- (1) The ambient temperature is -10 + 40 ; the relative humidity of Zmjt05 environment does not exceed 400-06805395% (+ 25 ); the altitude is below 2000 meters.
(2) The methane, coal dust, hydrogen sulfide, and carbon dioxide in the surrounding air must not exceed the safe content stipulated in the Coal Mine Safety Regulations.
(3) The working system is a low-speed heavy-duty discontinuous type.
- The motor is mounted on the base and connected to the worm gear reducer through a coupling. The power is transmitted to the arc surface worm and worm gear through a pair of gears. Wire rope for work.
- The winch is transmitted to the drum by a motor via a coupling, a closed gear transmission, a spherical worm transmission, and a cylindrical gear transmission (with a bridge gear in the middle). The main rotating parts in the winch are supported by rolling bearings, and the base is welded by profile steel. The winch is symmetrically arranged, has a long shape, and the topping column (fixed) has a spacious position, which is convenient for the winch to be moved and fixed. The width and height of the winch are small and suitable for underground use. The winch has a simple structure and is easy to maintain. It uses a spherical worm to rotate smoothly, safely and reliably. The operation of the winch is relatively simple, as long as the on / off button switch is sufficient.
