Reducer (gearbox) model list

The reducer is a relatively precise machine, and its purpose is to reduce the speed and increase the torque. There are many types, different models, and different types have different uses. There are many types of reducers, which can be divided into gear reducers, worm reducers and planetary gear reducers according to the transmission type; according to the transmission stages, they can be divided into single-stage and multi-stage reducers; according to the gear shape, they can be divided into cylindrical gear reducers The speed reducer, the bevel gear reducer and the bevel-cylindrical gear reducer; according to the arrangement of the transmission, it can be divided into the expansion type, split type and coaxial type reducer. The following are commonly used reducer classifications:

Planetary cycloidal pin gear reducer Worm gear reducer Gear reducer Planetary gear reducer Geared motor
Infinitely variable speed reducer Special special reducer Harmonic reducer Three-ring reducer Belt drive reducer
Enterprise standard reducer (device) reducer accessories precision reducer combined reducer AC reducer motor
Sinking reducer Parallel shaft reduction motor Micro DC reduction motor Spur gearbox reduction motor
Features
The main feature of the worm gear reducer is that it has a reverse self-locking function and can have a larger reduction ratio. The input shaft and the output shaft are not on the same axis or on the same plane. But generally the volume is large, the transmission efficiency is not high, and the accuracy is not high. The harmonic drive of the harmonic reducer uses the controllable elastic deformation of the flexible element to transmit movement and power. The volume is small and the accuracy is high. However, the disadvantage is that the flexible wheel has limited life and is not impact resistant. The rigidity is compared with metal parts. difference. The input speed cannot be too high. The advantages of planetary reducer are compact structure, small return clearance, high accuracy, 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 a modular combination system. There are a lot of motor combinations, installation forms and structural schemes, and 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 model that adopts the principle of cycloidal pin tooth meshing planetary transmission. It is an ideal transmission device with many advantages, a wide range of uses, and can run forward and backward.
Features
1. The transmission ratio is large. The transmission ratio is 1/6-1/87 in the first deceleration. The transmission ratio for two-stage reduction is 1/99–1/7569; the transmission ratio for three-stage transmission is 1/5841-1/658503. In addition, multi-stage combination can be used according to needs, and the speed ratio can reach the specified value.
2. High transmission efficiency. Because the meshing part adopts rolling meshing, the general first-level transmission efficiency is 90%-95%.
3. Compact structure, small size and light weight. Compared with ordinary cylindrical gear reducer, the volume can be reduced by 2/1-2/3.
4. Fewer failures and long life. The main transmission engaging parts are made by grinding bearing steel, so the mechanical properties and wear resistance are good, and because it is rolling friction, there are few failures and long life.
5. Smooth and reliable operation. Due to the multi-tooth meshing during the transmission process, it runs smoothly and reliably with low noise.
6. Convenient disassembly and assembly, and easy maintenance.
7. Strong overload capacity, impact resistance, low moment of inertia, suitable for frequent starting and forward and reverse rotation.
Worm gear reducer
HW type straight profile toroidal worm reducer (JB/T7936-1999) is called a straight profile toroidal worm (also known as a spherical worm) because of the toroidal worm pair adopted, and its axial section tooth profile of the worm is a straight line. , Same as other kinds of worm reducers, it is a spatial cross-shaft transmission with high load carrying capacity and transmission efficiency. It is suitable for heavy load, high power and high torque transmission, such as metallurgy, mining, lifting, transportation, petroleum, chemical industry , Reduced transmission of construction and other mechanical equipment. Including HWT, HWWT, HWB, HWWB four types.
Working conditions: The staggered angle of the input and output shafts is 90℃; the worm speed does not exceed 1500r/min; the sliding speed of the worm’s intermediate plane indexing circle does not exceed 16m/s; the worm shaft can run forward and backward; the working environment temperature is -40 ℃~40℃. When the working environment temperature is lower than 0°C, the lubricating oil must be heated to above 0°C before starting, or lubricating oil with a low freezing point must be used; when it is higher than 40°C, cooling measures must be taken.

Low speed, low frequency
JWM type (trapezoidal screw type) is suitable for low speed and low frequency occasions. The main components are: precision trapezoidal screw pair and main precision worm gear pair.
1 Economy:
Compact structure, simple operation and convenient maintenance.
2 Low speed, low frequency:
It is mainly used in places with heavy load, low speed and no frequent work.
3 Maintain the load: The trapezoidal screw has an automatic locking function, which can maintain the load even without a braking device.
When subjected to large vibrations and shock loads, the self-locking function will occasionally fail, and a braking device must be added at this time.
Electric drum

Electric drums are mainly used as the driving device of fixed and mobile belt conveyors. Because the motor and reduction mechanism are built in the drum, it has more advantages than the traditional open driving device where the motor, coupling and reducer are placed outside the drum. It has the advantages of compact structure, stable operation, low noise, convenient installation, etc., suitable for working in various environments such as dust and damp mud. With the wide application of electric rollers, a structure with a built-in deceleration mechanism outside the motor is formed, which properly solves the heat dissipation problem of high-power and small-size electric roller motors, and makes maintenance and repair more convenient, which is quite popular with users. . At present, electric rollers have been widely used in various fields of the national economy. The electric drum produced by our factory has three transmission modes: fixed shaft gear and planetary gear cycloid pin. The installation types include built-in motor, external and mobile type. When the motor is built-in, there are two types of oil cooling and oil immersion. Compared with general deceleration mechanism, it has the advantages of compact structure, light weight, good sealing performance and convenient installation, which is well received by customers. It mainly includes YD gear roller, DYI gear roller, QD transformation cycloid roller, YBT cycloid built-in roller, JZ, JZN type high-power aluminum roller, JX type high-power roller, WBT cycloid external roller, WDT type external roller.
Electric drums are widely used in mining, metallurgy, chemical, coal, building materials, power, food and transportation sectors.
The roller component is a transmission roller group and a reversing roller group. The transmission roller is the main part of transmitting power. The roller group has a smooth surface and a rubber surface. The shape of the rubber surface can be divided into smooth rubber, chevron rubber and diamond rubber to adapt to different Process requirements. The reversing rollers are divided into smooth rubber and smooth steel rollers according to the structure and are divided into light, medium and heavy series. All rollers adopt one-piece bearing housing and are lubricated with grease. The roller shaft is made of 45 steel, the bearing seat has cast iron castings, and the barrel adopts welded parts. The drum structure is reasonable, the selection is convenient, the performance is reliable, and the service life is long. Maintenance-free for 5-10 years under normal use conditions.
