The shifting Gearbox is the core device in the mechanical transmission system. It achieves flexible conversion of speed and torque during power transmission by changing the meshing relationship of gears, thus meeting the needs of mechanical operation under different working conditions. It is composed of key components such as the driving gear, driven gear, shaft parts, housing, and shift control mechanism, all of which are precisely matched to ensure the efficiency and stability of power transmission.

The shifting gearbox, with its excellent transmission performance, has become an indispensable and important component of many mechanical equipment. It can be seen in mobile devices such as automobiles and construction machinery, as well as fixed machinery such as machine tools and power generation equipment, providing solid power support for the normal operation of various types of machinery.

Efficient power transmission

The shifting gearbox adopts high-precision gear machining technology, with reasonable gear tooth design and precise control of meshing clearance, which can effectively reduce energy loss during power transmission and achieve high transmission efficiency. This means that with the same power input, more effective power can be output, improving the efficiency of mechanical work.



Flexible adjustment of speed and torque

By combining different gears for shifting, the shifting gearbox can achieve multiple outputs of speed and torque. Operators can quickly and conveniently change the operating speed and output force of machinery according to actual work needs, so that the machinery can maintain optimal working conditions in different working environments.



Compact and durable structure

The gearbox body is usually cast from high-strength alloy materials, which have good rigidity and impact resistance, and can withstand large loads and vibrations. The internal gears and shaft components undergo strict heat treatment processes, significantly improving wear resistance and fatigue strength, greatly extending the service life of the gearbox.



Easy and stable operation

Equipped with advanced shift control mechanism, the shifting process is lightweight, smooth, and has high shifting accuracy, which can effectively avoid problems such as shifting shock and disengagement. The gearbox is equipped with a comprehensive lubrication and cooling system inside, ensuring that all components receive sufficient lubrication and cooling during operation, ensuring stability and reliability of operation.

New energy vehicles and commercial vehicles

Multi-gear electric drive system: 

adapted to the 800V high-voltage platform, it supports electric vehicles to reduce the motor speed when cruising at high speed, and improve the cruising range by 10%-15%.

Hybrid system: 

seamless switching between fuel engine and motor is achieved through the dual-clutch structure, meeting the efficient power distribution requirements of plug-in hybrid vehicles (PHEV).

Industrial automation and robots

High-precision positioning equipment: 

gearboxes are used in semiconductor manufacturing equipment, with a transmission accuracy of ±1 arc minute and a repeat positioning accuracy of ≤±0.1mm, which helps to achieve nano-level operations of chip packaging.

Heavy machinery drive: 

In mining excavators, gearboxes can withstand 200-ton loads to ensure the stability of continuous operation.

Installation and commissioning

Gear alignment procedure:

 When assembling the main gearbox, ensure that the marks of the primary gear and the intermediate gear are aligned. The auxiliary gearbox needs to check the clearance between the synchronizer lock pin and the cone ring (standard value 0.05-0.15mm).

Lubrication system: 

The lubricating oil needs to be replaced after the first 500 hours of operation, and then every 2000 hours or half a year. It is recommended to use GL-5 synthetic gear oil (viscosity index ≥140).

Operation specification

Shifting logic:

Avoid rapid acceleration and shifting during high-speed driving. It is recommended to operate after the engine speed stabilizes. Automatic transmission models can enable "Economy Mode" to optimize the shifting timing through intelligent algorithms.

Environmental control: 

The operating temperature needs to be controlled between -20℃ and 85℃, and the humidity ≤85% RH. In high-salt environments, anti-corrosion coating inspections are required every quarter.

Intelligent operation and maintenance

Online monitoring: 

Check the parameters such as gear oil dielectric constant and metal abrasive concentration in real time through the IoT platform. When the iron-based abrasive increases suddenly (>80 pieces/mL), the system automatically triggers a level 3 alarm and generates a maintenance work order.

Software upgrade: 

Regularly update the control module firmware to optimize the smoothness of gear shifting.
