ZSC type cylindrical gear reducer:
ZSC reduction machine is based on the design and manufacturing experience of domestic and foreign similar products, and has been refined and optimized to be widely used in metallurgy, machinery, petroleum, chemical, construction, textile, light industry and other industries.
ZQA cylindrical gear reducer:
ZQA type reducer is improved on the basis of ZQ type reducer. In order to improve gear bearing capacity, it is easy to replace ZA type reducer. When the shape, shaft end and installation size are the same, change the gear pinion material. The gear shaft is 42CrMo, the large gear is ZG35CrMo, the quenched and tempered hardness gear shaft is 291-323HB, and the large gear is 255-286HB. ZQA type reducer is mainly used in lifting, mining, general chemical, textile, light industry and other industries.

The gear reducer is a separate closed transmission between the prime mover and the working machine. It is used to reduce the speed and increase the torque to meet the working needs. In some cases, it is also used to increase the speed. It is called the speed increaser.

working principle:
The gear reducer uses the gear transmission of all stages to achieve the purpose of speed reduction. The reducer is composed of gear pairs of various stages. For example, the gear can be driven by a small gear to achieve a certain deceleration, and then a multi-stage structure is adopted. , you can greatly reduce the speed.
In the long-term operation of the reducer, there are often faults such as wear and leakage. The most important ones are:
1. The bearing chamber of the reducer is worn, which in turn includes the wear of the bearing housing of the housing, the bearing chamber of the housing, and the bearing chamber of the transmission.
2. The shaft diameter of the gear shaft of the reducer is worn, and the main wear parts are in the shaft head and keyway.
3. The bearing position of the reducer drive shaft is worn.
4. The reducer joint surface leaks.

For the wear problem, the traditional solution of the enterprise is repairing after repair welding or brush plating, but both have certain drawbacks: the thermal stress generated by the repair welding high temperature cannot be completely eliminated, which may cause damage to the material and cause the parts to bend or break; Brush plating is limited by the thickness of the coating, and it is easy to peel off. The above two methods use metal to repair the metal, which can not change the "hard to hard" coordination relationship. Under the combined action of each force, it will still cause re-wear. For some large bearing enterprises, it is impossible to solve on-site, and it is necessary to rely on external repair. In the contemporary Western countries, the repair method of polymer composite materials is often used for the above problems, and the application has more comprehensive properties such as superior adhesion and excellent compressive strength. The application of polymer material repair can be free of disassembly and machining without the influence of repair welding thermal stress, and the thickness of the repair is not limited. At the same time, the metal material of the product does not have the concession, which can absorb the shock vibration of the equipment and avoid the wear again. It is possible, and greatly extends the service life of equipment components, saving a lot of downtime for the enterprise and creating huge economic value.

For the leakage problem, the traditional method needs to disassemble and open the reducer, replace the sealing gasket or apply the sealant, which is not only time-consuming and laborious, but also difficult to ensure the sealing effect, and leakage will occur again during operation. The polymer material can be used to treat leakage on site. The material has excellent adhesion, oil resistance and 350% elongation, which overcomes the impact caused by the vibration of the reducer, and solves the problem of leakage of the reducer for the enterprise.

classification:
When selecting the reducer, according to the selection conditions of the working machine, technical parameters, performance of the power machine, economy and other factors, compare the outer dimensions of different types and types of reducers, transmission efficiency, load capacity, quality, price, etc. Reducer.
The load state of the working machine connected with the reducer is complicated, and has a great influence on the reducer. It is an important factor in the selection and calculation of the reducer. The load state of the reducer is the load state of the working machine (slave), which is usually divided into three. Class: 1 - uniform load, 2 - medium impact load, 3 - strong impact load.

transmission:
A gear reducer is a type of transmission that increases the wear of its internal transmission as it works longer. So what aspects should we analyze the wear of the internal gear of the gear reducer? The losses in the gear unit (gear frame and reducer) in the gear reducer include the following three aspects:
1. Sliding friction loss between teeth.
2. Loss in bearings, plain bearings and rolling bearings.
3. Splash and agitation of lubricant loss.
The loss problem in the gear reducer is related to the friction loss in the gear transmission, the friction loss of the rolling and sliding bearings, and the consumption and viscosity of the lubricating oil.

Gear reducer use, maintenance and precautions
1. The reducer adopts 460# medium load industrial gear oil, and the working environment temperature is 0~40°C.
Second, after the first use for 100 hours, the inner cavity should be cleaned and replaced with new gear oil, and the oil should be changed every 2000 hours.
3. When disassembling and installing the reducer, hammering should be avoided as much as possible to avoid damage to normal parts.
4. If it is found that there is oil leakage at the shaft extension or joint during use, the seals such as the skeleton oil seal should be replaced in time.

Precautions:
Leakage cause
1. The pressure in the fuel tank rises.
In the closed reducer, each pair of gears meshes with each other to generate heat. According to the Boeing's law, as the running time is lengthened, the temperature inside the gearbox is gradually increased, and the volume inside the chassis is reduced. It does not change, so the pressure inside the box increases, and the lubricating oil in the box is splashed and sprinkled on the inner wall of the reduction chassis. Because the oil has a relatively high permeability, under the pressure inside the box, which one is not tightly sealed, the oil will seep out from there.
2. The structural design of the reducer is unreasonable and causes oil leakage.
If the designed reducer does not have a hood, the reducer cannot achieve equalization, resulting in higher and higher pressure inside the tank and oil leakage.
3, too much fuel
During the operation of the reducer, the oil pool is stirred a lot, and the lubricating oil splashes everywhere in the machine. If the amount of oil is too much, a large amount of lubricating oil accumulates in the shaft seal, joint surface, etc., resulting in leakage.
4, improper maintenance process
During equipment maintenance, oil leakage may occur due to incomplete removal of dirt on the bonding surface, improper selection of sealant, reverse orientation of the seal, and failure to replace the seal in time.

Treatment plan:
Reducer oil leakage
The polymer composite material is used to repair and treat the leakage oil of the reducer. The polymer composite material is made of high molecular polymer, metal or ceramic ultrafine powder, fiber and the like, and is compounded by the curing agent and the curing accelerator. s material. Various materials complement each other in performance and produce synergistic effects, so that the overall performance of the composite material is superior to the original constituent materials. With strong adhesion, mechanical properties, and chemical resistance, it is widely used in metal equipment for mechanical wear, scratches, pits, cracks, leaks, repair of sand holes, etc., as well as various chemical storage tanks. Chemical corrosion protection and repair of reaction tanks and pipelines.

The main feature of the worm gear reducer is that it has a reverse self-locking function and can have a large reduction ratio. The input shaft and the output shaft are not on the same axis, nor on the same plane. However, the volume is generally large, the transmission efficiency is not high, and the accuracy is not high. The harmonic drive of the harmonic reducer is the elastic deformation controlled by the flexible element to transmit motion and power. The volume is small and the precision is high, but the disadvantage is that the flexible wheel has limited life and is not impact resistant. The rigidity is compared with the metal parts. difference. The input speed cannot be too high. The planetary reducer has the advantages of compact structure, small return clearance, high precision, long service life and large rated output torque. But the price is slightly more expensive. The gear reducer has the characteristics of small size and large transmission torque. The gear reducer is designed and manufactured on the basis of the modular combination system. There are many motor combinations, installation forms and structural schemes. The transmission ratio is finely graded to meet different working conditions and realize electromechanical integration. The gear reducer has high transmission efficiency, low energy consumption and superior performance. The cycloidal pinwheel reducer is a transmission type that adopts the principle of cycloidal pin gear meshing planetary transmission. It is an ideal transmission device with many advantages, wide application and forward and reverse operation.

The speed reducer plays a role of matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator, and is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It has a wide variety of models, different models, and different types of uses. There are many types of reducers. According to the transmission type, they can be divided into gear reducers, worm reducers and planetary gear reducers. According to the different drive stages, they can be divided into single-stage and multi-stage reducers. According to the gear shape, they can be divided into cylindrical gears. , bevel gear reducer and cone-cylindrical gear reducer; according to the transmission arrangement can be divided into expansion, split and coaxial reducer.The reducer is generally used for transmission equipment with low speed and high torque. The motor, internal combustion engine or other high-speed power is driven by the gears with few teeth on the input shaft of the reducer to mesh the large gear on the output shaft to achieve the purpose of deceleration. The reducer will also have several pairs of identical principle gears to achieve the desired deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

effect:
1. Reduce the speed and increase the output torque at the same time. The torque output ratio is multiplied by the motor output and the reduction ratio, but it should be noted that the rated torque of the reducer cannot be exceeded.
2. Deceleration also reduces the inertia of the load, and the reduction of inertia is the square of the reduction ratio.
