Hand drill planetary gear lubricating oil selection skills
Working principle and lubrication of planetary gear of electric drill
The planetary gear of electric drill is one of the most important parts in electric drill. Its working principle is to enlarge the torque and adjust the speed of electric drill through the coordination and rotation of planetary gear. However, planetary gears are vulnerable to wear and damage under higher working loads, so the correct selection and use of lubricating oil is crucial to the performance and life of the drill.
Second, the lubricating oil selection skills of the planetary gear of the electric drill
The lubricating oil type of planetary gear of hand drill can choose gear oil or light oil. The choice of these two lubricating oils should be determined according to the use environment and work intensity of the electric drill.
Gear oil
Gear oil is suitable for large mechanical equipment and high-speed heavy duty planetary gear lubrication, its advantages are good viscosity, wear resistance and extreme pressure, can resist high temperature and extreme pressure. However, for small electric tools such as hand drill, it may be too dense, resulting in excessive friction, reducing the efficiency and life of the hand drill, so it is recommended to choose the appropriate oil within the viscosity range of the gear oil according to the use of the hand drill.
2. Light oil
Light oil, also known as low-viscosity oil, is usually suitable for high-speed and small planetary gear lubrication, its advantages are lower viscosity, easy flow and heat dissipation, can reduce wear and noise. Generally speaking, the viscosity of light oil is between 20 and 30, which can be applied to the lubrication of small planetary gears such as hand drills.
Third, the use of hand drill planetary gear lubricating oil skills
1. Change the lubricating oil regularly
No matter which lubricant is selected, it needs to be replaced regularly, and the recommended replacement cycle is carried out after 6 months or 100 hours of use of the hand drill. Expired lubricating oil may produce acidic substances due to oxidation, accelerating the wear and corrosion of planetary gears.
2. Pay attention to lubrication
The lubrication amount of the planetary gear of the electric drill also needs to be paid attention to, too much or too little lubricating oil will negatively affect the performance and life of the electric drill. It is recommended to use an oil can or oiler for lubrication to ensure the appropriate amount and uniformity of lubricating oil.
3. Select the appropriate ambient temperature for use
The viscosity and fluidity of lubricating oil will be affected by temperature, so it is necessary to choose the appropriate ambient temperature when using lubricating oil. If the ambient temperature is low, you can choose a lubricating oil with less viscosity, if the ambient temperature is high, you can consider choosing a gear oil with better thermal resistance.
【 Conclusion 】
The lubricating oil selection and use of the planetary gear of the electric drill has a great impact on its performance and life, and choosing the right lubricating oil can make the electric drill more durable and reliable. When selecting lubricating oil, it is necessary to consider the use environment and work load of the electric hand drill, select the appropriate type of lubricating oil, and pay attention to the replacement and use of lubricating oil skills to meet the lubrication needs of the planetary gear of the electric hand drill.
