In today's era of rapid development in industrial automation and service robots, robot dexterous hands (also known as end-effectors of manipulators) are becoming increasingly "human-like" — flexible, precise, and efficient.
However, behind their "dexterity" lies a key support — the choice of lubricating grease. So, which parts of a robot dexterous hand need oil? Why is lubrication necessary?
I. Lubrication Parts of Robot Dexterous Hands
- Joint servo reduction mechanism: Contains precision planetary gears/harmonic reducers, used to control the bending and stretching of knuckles, and is the core moving part.
- Bearings and rotating joints: The rotation points that support the free movement of the dexterous hand. High-frequency start-stop and repeated movements lead to severe wear.
- Fingertip slide rails/linkage mechanisms: Parts used for gripping and force transmission, requiring smooth movement and precise positioning.
- Micro gear sets: In small dexterous hands, gears are often used for motion synchronization or torque transmission. Poor lubrication can cause abnormal noise or jamming.
Why do robot dexterous hands need lubrication? As precision mechanical structures, their joints and micro-components are prone to frictional resistance during high-speed operation, leading to delayed movements, frequent noise, and even accelerated wear that shortens their service life.
The core role of lubrication is to form a stable oil film, reduce frictional loss between components, make joint movements smoother and more sensitive, and reduce mechanical noise.
In addition, high-quality lubricating grease can resist the impact of high and low-temperature environments, avoid control accuracy deviations caused by poor lubrication, and ensure the stable operation of dexterous hands from multiple dimensions such as wear resistance protection and environmental adaptability. It is a key link to improve their control performance and service life. Baoxing's robot-specific grease series reduces noise, absorbs vibrations and impacts effectively while lubricating, enabling quieter operation. It provides long-lasting lubrication, forming a strong oil film to adapt to high-speed, low-load, and high-frequency start-stop conditions. It has good compatibility with plastics/rubbers/metals, without corroding structures or dissolving seals. It can also customize consistency and additive formulas to tailor lubrication solutions for different joint parts.
