Vacuum gearbox, as a transmission device used in a vacuum environment or under specific process requirements, has its unique design characteristics and application scenarios.
1、 Definition and Characteristics
A vacuum gearbox, as the name suggests, refers to a gearbox that can operate normally in a vacuum environment. It usually has the following characteristics:
Excellent sealing performance: Due to the special working environment, the vacuum gearbox must have good sealing performance to prevent a decrease in vacuum degree or the entry of external impurities.
Strict material selection: Its internal components and materials need to undergo special treatment or be made of corrosion-resistant and wear-resistant materials to adapt to vacuum environments and possible radiation, chemical corrosion, and other factors.
Efficient transmission: The vacuum gearbox needs to ensure efficient transmission performance under vacuum conditions to meet the equipment's requirements for speed and torque.
Easy maintenance: When designing, the need for easy maintenance and repair should be considered, such as setting up easy to observe sight hole covers, easy to replace lubrication systems, etc.
2、 Working principle
The working principle of a vacuum gearbox is similar to that of a regular gearbox, which uses the meshing of gears to reduce speed and increase torque. When power is transmitted from the input shaft to the gearbox, it is gradually reduced by gears, and finally the output shaft outputs the reduced speed and increased torque. In a vacuum environment, special consideration should be given to the lubrication and heat dissipation of the gears inside the gearbox to ensure its normal operation and long-term stability.
3、 Application scenarios
Vacuum gearboxes are widely used in fields that require maintaining a highly pure environment, such as semiconductor manufacturing, aerospace, vacuum coating, vacuum heat treatment, and other industries. Specific application scenarios include but are not limited to:
Semiconductor manufacturing equipment: During the semiconductor wafer processing, a vacuum gearbox is used to drive precision robotic arms, transmission mechanisms, etc., ensuring that the wafer is processed in a highly pure vacuum environment.
Aerospace equipment: In the aerospace field, vacuum reducers can be used to drive precision mechanisms of space telescopes, satellites, and other equipment to meet their stable operation requirements in high vacuum and low temperature environments.
Vacuum coating equipment: During the vacuum coating process, the gearbox is used to drive the coating turntable, conveyor belt, and other components to ensure coating uniformity and product quality.
