Trimmer gear box grease selection optimization: improve performance and reduce maintenance costs
Pruning shears are an indispensable tool in horticultural work, and their performance directly affects the efficiency and durability of the tool. However, many pruning shears often encounter problems such as loud gearbox noise, easy to throw out grease and difficult to start at low temperatures during use, which not only reduce work efficiency, but also may accelerate tool wear and increase maintenance costs. In view of these pain points, choosing the right grease and carrying out the correct filling maintenance has become the key to improve the performance of pruning shears.
Selection of grease: dual considerations of performance and suitability
When the gear in the gear box of the pruning shears is running at high speed, it will produce a lot of friction and heat, and if the lubrication is poor, it will lead to increased noise and increased wear. Therefore, choosing the right grease is crucial. The ideal grease should have the following characteristics:
1. Extreme pressure wear resistance: electric tools such as pruning shears are often accompanied by severe speed changes, discontinuous lubrication and high impact load in the gear transmission process, so the grease needs to have good extreme pressure anti-wear performance to effectively reduce gear wear.
2. Adhesion and oxidation resistance: under high-speed operation, ordinary grease is easy to be thrown out, resulting in insufficient lubrication. Therefore, a grease with strong adhesion should be selected to ensure that continuous lubrication and protection can be provided when the gear is running at high speed. At the same time, good oxidation resistance can extend the service life of the grease and reduce the frequency of replacement.
3. High and low temperature resistance: During the use of pruning shears, the internal temperature of the gear box will rise rapidly, and it is necessary to ensure that the equipment can start smoothly in a low temperature environment. Therefore, the grease needs to have excellent high and low temperature performance to adapt to the needs of different working environments.
Filling and maintenance of grease
After choosing the right grease, the correct filling and maintenance methods are equally important. Here are some key steps:
1. Inspection and replacement: Before use, the appearance and quality of the grease should be checked to ensure that it has no odor, discoloration or deterioration. If any problem is found, stop using the grease immediately and replace it with a new grease. At the same time, according to the advice of the equipment manufacturer and the life of the grease, a reasonable replacement cycle is developed, usually every 6 months to 1 year.
2. Cleaning and drying: The cleaning and drying of grease storage containers is crucial to maintaining their quality. Ensure that there is no dust, impurities or moisture in the container, so as not to affect the performance of the grease.
3. Correct filling: Use the correct grease filler, select the appropriate grease according to the equipment manufacturer's recommendations, and ensure that the amount of filling is moderate. Too much or too little grease will affect the lubrication effect and even cause damage to the equipment.
4. Regular inspection: In the process of use, the use of grease should be regularly checked. By observing the lubrication state, temperature and noise indicators of the equipment, determine whether the grease is working normally. If it is found that the lubrication effect is not good, it should be stopped in time and the grease should be checked and replaced.
Innovative lubrication method
In addition to choosing the right grease and proper filling maintenance, you can also try innovative lubrication methods to further enhance the performance of pruning shears. For example, the centrifugal lubrication method is used to drill holes at the bottom of the gear box and use the characteristics of centrifugal force to inject and exclude lubricants, which can effectively reduce noise and improve lubrication effect. In addition, improving the meshing accuracy of the gear by modifying the tooth shape is also an effective means to reduce the noise.
In short, choosing the right grease and carrying out the correct filling maintenance is of great significance to improve the performance of the pruning gear box, reduce noise, reduce wear and reduce maintenance costs. At the same time, combined with innovative lubrication methods, the overall performance of pruning shears can be further improved, making them more suitable for a variety of complex working environments.
