Reducer is a driving force transmission organization that converts the rated power of the motor into the required speed ratio according to the internal structure, and outputs a larger torque.
Function of reducer: 1 Reduce rotation rate by 2 Extended rotational force (torque)
Types, advantages and disadvantages of traditional reducer:
1】 Planetary reducer
Principle:
The inner ABS ring gear (a) is closely connected to the gearbox housing. The ABS ring gear management center has a sunlight transmission gear (b) driven by external driving force, and a group of three gears are driven close to each other (C) It is equally divided on the fixed support; when inputting the sunlight transmission gear of the side driving force driver, it can promote the gear transmission to rotate at a uniform speed, and carry out the rotation of the management center along the motion track of the inner ABS ring gear, and Z will finally output the low-speed rotation fitness movement of the big planet from the output fixed support.
Main purpose:
Packaging, packaging printing, laser cutting, dispensing, canning, production line and other automatic machinery.
Characteristics:
Light weight, small size, large reduction ratio, high efficiency, stable operation, low noise and strong adaptability. Generally, the speed reduction below 10 is one-stage speed reduction, the speed reduction above 10 is two-stage speed reduction, and the total transmission ratio is below 100. Two types of transmission gears, straight and helical, are selected.
Key defects:
The processing precision of raw materials and parts is high, the structure is cumbersome, and the production, manufacturing and installation are difficult.
2】 RV Reducer
Principle:
The gear transmission speed reduction organization is used as the primary speed reduction, and the cycloid needle wpx147 reducer speed reduction organization is used as the secondary speed reduction. According to the overall organization of the stiffness disk and the output disk, the speed reduction will be output after Z.
Main purpose:
6-axis industrial manipulator, 2 and 3 bone joints and other heavy-duty machinery and equipment.
Characteristics:
Large transmission ratio, large bending stiffness, strong impact resistance and strong bearing capacity. Compact structure, reliable application and long service life.
Key defects:
Large volume, heavy net weight, complex manufacturing process and a large number of parts.
3】 Harmonic wpx147 reducer
Principle:
The key is composed of four basic prefabricated components: wave generator, soft transmission gear, soft rolling bearing and rigid transmission gear. It is a transmission gear that causes controllable elastic deformation of the soft transmission gear by installing the soft rolling bearing on the wave generator and transmits the driving force of fitness movement by meshing with the rigid transmission gear. Generally, the number of flexible transmission gears is 2 less than that of rigid transmission gears. As a reducer application, wave generator active, small fixed and flexible wheel output mode is generally selected.
Main purpose:
The fourth, fifth and sixth bone joints of 6-axis industrial manipulator and its automation technology industry.
Characteristics:
The reduction ratio is large, and the unipolar coaxial output can obtain a high transmission ratio of 35 ~ 320. Small size and light weight. Simple structure, few parts and convenient installation. The transmission system has high efficiency and long service life.
Key defects:
The flexible wheel is easy to fatigue and damage, and the starting torque is large. It can not be used in places where the transmission ratio of the transmission system is lower than 35. The ability to bear large torque and impact load is limited. The precision cycle is short.
4】 Haishang vector material hard gear reducer
Principle:
The basic principle of overturning transmission gear does not select the transmission gear as the transmission system, takes the bearing steel ball as the transmission system component, and replaces the gear meshing with the gapless roller line gear pair composed of the roller line raceway. The basic principle of vector material rotary wheel line transmission system uses the input shaft (eccentric shaft) as the motion track generator to push the drive plate to do the axial force rotary wheel line uniform rotation fitness exercise. According to the transmission structure of one or two groups of cross turn head lamp discs, the drive plate rotates at a uniform speed and transmits it to the output end through the bearing steel ball to complete the speed reduction.
Main purpose:
Intelligent robot whole bone joint application, new energy vehicles, precision machines, medical devices, packaging and printing and other industries.
Characteristics:
The ball bead structure is beneficial to heat conduction, reduce the temperature rise and noise of the reducer and improve the service life. It has the advantages of compact structure, low noise, light weight, small size, zero back clearance, stable transmission system and high output precision, and the high efficiency of transmission system is more than 93%.
