Gearbox Buying Guide
Gearbox
Gearbox is an important part widely used in the rotation of the system. It consists of two or more gears, including at least one drive gear with a certain diameter, and one smaller gear connected to the drive mechanism (electric motor, wind turbine, diesel generator, and so on).
You need to understand the purpose of the gearbox, so that you can choose and buy the gearbox that is suitable for us.
Gearbox is widely used, it mainly has the following functions:
- Acceleration and deceleration are often referred to as speed change gearboxes.
- Change the transmission direction. For example, we can use two sector gears to transmit the force vertically to another rotating shaft.
- Change the torque. Under the same power conditions, the faster the gear rotates, the smaller the torque on the shaft, and vice versa.
- Clutch function: We can achieve the purpose of separating the engine from the load by separating the two originally meshed gears.
- Distribute power. For example, we can use one engine to drive multiple slave shafts through the main shaft of the gearbox, so as to realize the function of one engine driving multiple loads.
Today we will introduce the characteristics and applications of several gearboxes, so that you can have a clearer understanding of the gearbox. It is convenient for you to make the best choice when purchasing.
Planetary Gearbox
The planetary gear box is the planetary reduction box. Its structure is a mechanism in which multiple planetary gears rotate around a sun gear. It is also a mechanism for reducing the transmission speed ratio and increasing the torque of the motor proportionally. You need to know the following aspects when buying a planetary gearbox:
Features: Compared with the same kind of ordinary gear box, it has smooth transmission, large bearing capacity, and large transmission ratio in small space, especially longevity. If the gears are steel, the lifespan can reach 1000Y. Its size is small and it looks beautiful.
Application: Planetary gearboxes are widely used. They are initially used in conjunction with motors. In addition to being used for micro gear motors, they are also used in office automation, smart home, production automation, medical equipment, financial machinery, game consoles and other fields in the sunshade industry. Such as automatic curtains, smart toilets, lifting systems, money counters, advertising light boxes and other industries.
Worm Gearbox
The worm gearbox is a gearbox that changes the transmission ratio and the direction of movement. It is designed between the clutch and the center drive.
When purchasing, you need to understand the following functions:
Under the condition that the engine speed and torque remain unchanged, the driving force and driving speed of the vehicle are changed (shifting); the vehicle can be driven backward (reversing); the engine can be stopped without turning off (neutral). When the car is running, in order to adapt to different working conditions, the driving force and speed of the car need to be changed within a certain range, and the torque and speed change range of the existing engine cannot meet this requirement, so a gearbox is designed.
The worm gearbox works as follows:
- Change the transmission ratio between the engine and the wheels, so that the engine works under the best working conditions, expands the torque and speed transmitted by the engine to the driving wheels, and obtains different speeds;
- It enables the car to run backwards;
- It can set neutral.
Right angle gearbox
Right-angle gearboxes are divided into orthogonal gearboxes or skew gearboxes.
If you know more about it, it will be more convenient for your purchase.
The right-angle gearbox can transmit the power of the horizontal shaft of the prime mover to the vertical pump shaft, and it has the characteristics of economy, high efficiency and space saving. The right angle gearbox can directly bear the possible axial force of the working machine and simplify the structure of the working machine.
The right angle gearbox is directly matched with the diesel engine, horizontal motor or steam turbine, and is used for the transmission and speed change of various pumps such as vertical long-shaft fire pumps, deep well pumps, oblique flow pumps, axial flow pumps, and submerged pumps. Right-angle transmission and speed change of vertical shaft machinery
