As one of the commonly used deceleration equipment in the factory production workshop, the speed  WPWV80,WPWV100,WPWV120,WPWV135,WPWV155 reducer should have control over speed changes to control heating failures caused by speed reduction. Pitting corrosion, a destructive and hidden form of corrosion, inevitably occurs on machines in chemical factories. What should be done if similar pitting occurs in the reducer? The editor teaches you two tips:Firstly, analyze the corrosion situation based on the material and deal with the occurrence of pitting corrosion in advance. Moreover, the degree of...

When the WPWKT155,WPWKT175,WPWKT200,WPWKT250,WPWDKT40 reducer is running, it often produces loud noise but no vibration, and the surface of the teeth is worn and corroded by iodine. According to the oil standard, there is no shortage of oil. If this problem cannot be solved for a long time, it will affect the working efficiency of the reducer, and even shorten its service life in serious cases. If we want to solve this problem, we need to know what causes the machine to make huge noise. The reducer manufacturer has introduced the following noise causes to us.1. Excessive bearing clearance...

The WPWDX250,WPWS40,WPWS50,WPWS60,WPWS70 cylindrical gear reducer is a power transmission mechanism that utilizes the speed converter of the gear to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque. With the continuous application of deceleration equipment in enterprises, in some cases it is necessary to disassemble the equipment in order to clearly see the internal structure and carry out targeted maintenance. What are the methods for disassembling the equipment? Let's go and have a look together.Reducer1. Remove the cylindrical...

The reducer is one of the main equipment of the enterprise. Once the fit clearance occurs in the operation process, it will cause serious damage to the transmission shaft and transmission gear, causing major shutdown accidents, and the enterprise will suffer huge economic losses. Once the bearing housing of the reducer is worn, the replacement cost of the parts is high and the manufacturing cycle is long. The general repair method is to machine or expand the hole and insert the steel sleeve after disassembly and repair welding, which is time-consuming and costly. In western countries, polymer ...

Planetary reducer is a widely used traditional equipment for reducing speed. Planetary reducer achieves transmission accuracy mainly through the cooperation between gears. Many people don't know what the return clearance of the planetary reducer is. The small editor of Zhuochuang Transmission Technology will give you a brief introduction.Clearance refers to the clearance between gears. It is generally called return clearance, also called back clearance. The return clearance (or back clearance, clearance) in the neutral energy parameter of the planetary reducer, the lower the value is, the...

As an essential component of automatic equipment and other mechanical equipment transmission products, the hard gear reducer plays an important role in the stability of the entire transmission system, and has the advantages of small size, high life, high accuracy and no oil leakage. Its gear is made of high-strength low-carbon alloy steel through carburizing and quenching. The gear has high hardness. The gear adopts the process of CNC grinding. It has the characteristics of high precision, good contact, high transmission efficiency, smooth operation and low noise. It also has strong pitting...

Then install a small grinding head on the lathe tool holder, stop grinding locally for wire cutting, confirm the basic size, and then draw the axial bisector on the machining surface after removal, and use 1. The 0 mm cutting blade is grinded out three layers in the axial direction with a depth of 0. 5mm groove is used for threading process of wire cutting machine again. At the same time, a wheel inner hole sleeve with Gr15 heat treatment hardness of HRC58-62 was processed, and the inner hole size was 0 smaller than the outer hole size. 5mm, the surface roughness reaches Ra0 after cylindrical ...

2. The shaft diameter of the gear shaft of the reducer is worn. The main wear parts are the shaft head, keyway, etc. 3. The bearing position of the gear shaft of the reducer is worn. 4. The leakage of the joint surface of the reducer is aimed at the wear problem. The traditional solution of the enterprise is to repair after repair welding or brush plating, but both of them have disadvantages: the thermal stress generated by the high temperature of repair welding can not be completely eliminated, which is easy to cause material damage, resulting in bending or fracture of the parts; However,...

The parts of the reducer, especially the transmission parts on the output shaft, must be carefully installed. It is forbidden to use tools such as hammers for explosive force installation. The transmission connection parts should be equipped with protective devices when necessary to ensure its transmission effect and service life. Although there are many types of couplings for gear reducers, it is not recommended to use rigid fixed couplings, because improper installation of such couplings will cause unnecessary additional loads, which not only wastes energy, but also easily causes bearing...

The use place of the reducer shall be separated from the thermal radiation. If it is assembled in a very hot and cold place, it is necessary to have cooling methods and heating lubricating oil to ensure normal startup.The concrete foundation or metal base plate of the reducer must be sufficiently rigid; The foundation bolts shall be buried to a sufficient depth, and the gasket shall be used for leveling, and the thickness of the gasket shall not be less than 1mm; To ensure that the load is stable and not deformed during operation.Leveling, centering with power machine and working machine shall...

Reducing and controlling the gear noise is the basis of reducing the noise of planetary reducer. To reduce the gear noise, we need to start from the structural design and gear accuracy.1. Requirements for low noise gear structure designThe influence of gear structure design on noise is very important. The ideal design is to improve the bending strength of the gear teeth as much as possible, select a larger modification coefficient and an appropriate helix angle to increase the meshing coefficient, so as to achieve the purpose of reducing noise. Therefore, according to this requirement, the...

Disadvantages of knocking method for planetary gear reducer assembly1. The knocking method will damage the surface of the reducer and affect the surface quality of the reducer. The uneven striking process is easy to cause the gear reducer to tilt during the assembly process, which brings difficulties to the assembly.2. The assembly of the reducer is a follow-up process, and the matched drive roller has been assembled on the lower frame. During the assembly of the reducer, the impact of the impact on the slide plate in the assembly of the tension leveler is easy to damage the slide plate;3. The...
