Introduction:

1. WP worm gear reducer,also known as WP reducer, is divided into standard WPS series, standard WPD series, standard WPA, WPO.WPDA.WPDO, WPDS, WPDS and so on. The WP worm gear reducer is developed on the basis of the WD reducer. The WP worm gear reducer is made of 45# high-quality steel by heat treatment. The worm wheel is cast with tin bronze, which has good wear resistance, especially in the bearing capacity.

2. It consists of a pair or pairs of meshing gears, worm gears, worms, etc., housed in a rigid, sealed enclosure, as a separate component in the machine. It is commonly used as a transmission for deceleration between the prime mover and the work machine. On the contrary, in a few occasions, such as a centrifugal compressor, it is necessary to apply a speed-increasing transmission, which is called a speed increaser.

3. The WP worm gear reduceris widely used in chemical plants, mechanical machines and engineering institutions due to its compact structure, high efficiency (gear reducer), accurate and reliable transmission movement, and maintenance and use. There are many types of reducers, which can be generally classified into gears (cylindrical gears, bevel gears) and worm gear reducers.

1. Working Principle

It is a kind of non-rigid coupling with liquid as working medium. The pump wheel of the hydraulic coupler (see figure) and the turbine constitute a closed working chamber for liquid circulation flow. The pump wheel is mounted on the input shaft and the turbine is mounted on the output shaft.

The two wheels are a half ring with many blades arranged along the radial direction. They are coupled to each other and are not in contact with each other. There is a gap of 3mm to 4mm in the middle, and a circular working wheel is formed. The driving wheel YOX Series Fluid Coupling is called the pump wheel, the driven wheel is called the turbine, and both the pump wheel and the turbine are called the working wheel. After the pump wheel and turbine are assembled, the annular cavity is formed, which is filled with working oil.

2. Classification

According to the different USES, the YOX Series Fluid Coupling can be divided into the general type of hydraulic couplers, limited torque type of hydraulic couplers and speed hydraulic couplers. Among them, the torque limited hydraulic coupler is mainly used for starting protection of motor reducer and impact protection during operation, position compensation and energy buffering. Speed-regulating hydraulic coupler is mainly used to adjust the speed ratio of input and output. Other functions are basically the same as the torque limited hydraulic coupler.

Rolling mill, which belongs to mechanical equipment, frame work rolls, etc., is durable. The design of the parallel shaft mounted speed reducer requires compact structure and high strength requirements. A composite reducer can be used, and the gears are made of high-strength alloy steel.

Structural features:

1. When the small-diameter work roll is used, the rolling pressure is also small, the pass processing rate can be increased, the rolling pass can be reduced, and the hard and thin hard-to-deform material can be rolled without intermediate annealing. At the same pass reduction, the rolling pressure is only one-third that of a four-high mill, reducing energy consumption.
2. The frame adopts integral cast steel. The rolling mill with parallel shaft mounted speed reducerhas great rigidity in the longitudinal and transverse directions; the deflection of the roll is very small, and the work roll can withstand large rolling pressure and horizontal strip tension to prevent the similar four-roll mill from slenderening. Side bend of the work roll. With a special roll type control device, it is possible to roll thin strips with high thickness and high straightness.
3. The rolling mill with parallel shaft mounted speed reducerhas a large opening degree, so the ability to wear the belt and handle the accident is greatly enhanced, the roll changing is convenient, the working rate is increased, and the rolling cost is low, which is only 40%-80% of the four-high rolling mill.
4. The roller system is a tower-shaped structure, the work roller is driven by the friction of the four intermediate rollers, and the combinedinline shaft three phase gearboxdistributes the power for the four output shafts.

The mill is also called vertical mill. The mill is operated intermittently, and the slag is manually loaded into the iron bowl-shaped grinding disc of the planetary gearbox flender for alstom mill, and is ground by a heavy grindstone, and the slag is crushed due to the weight of the grindstone itself. At the same time, because the distance between the points on the width of the grindstone is different from the central rotating shaft, the linear velocity of each point is different, so sliding friction occurs between the grindstone and the grinding disc, causing the slurry to be crushed and disintegrated.

The advantage of the planetary gearbox flender for alstom mill is that the operation is easy and the equipment is simple. The disadvantage is that the equipment is heavy, intermittent operation, labor intensity, large floor space, and difficult to clean in the factory. Previously, the device has been used more and has been gradually reduced. The mill is an industrial equipment widely used in the selection or rough selection of various ores such as metallurgy, iron selection, molybdenum selection, strontium selection, silver selection and lead selection.

Mill application and advantages and disadvantages

The earliest grinding was spring-loaded with smaller gauges. It is used to grind coal powder in power plants and cement plants, and later in the cement plant, a small amount is used to grind raw materials. Hydraulic large-scale milling, which has been manufactured in recent years, is mainly used to grind raw materials in cement plants, and it accounts for an increasing proportion of raw material production.

Milling is usually carried out by hot air flow during drying. In recent years, the use of suspended preheating kiln and waste heat from the kiln outside the kiln has been mainly utilized. Since the planetary gearbox flender for alstom mill itself has a classifier or separator, the milled air stream containing the fine powder is collected by the dust collector to grind the finished product.
