The "lubrication code" of power tools is selected with the right oil, and the efficiency is doubled
Since the advent of the first direct current electric drill in 1895, various types of power tools, convenient to carry and simple to operate, have gradually become an irreplaceable "efficiency tool" in the construction, automobile, machinery, home improvement and other industries. Its emergence not only reduces people's labor intensity, improves work efficiency, but also helps the development of the electrical industry, and brings a new look to the world.
Why is lubricating grease so important?
Although the "efficiency weapon" is good, it can occasionally encounter troubles in use. I believe that users have encountered problems such as power tool temperature rise, abnormal noise, oil leakage and so on in the operation, these problems do not seem serious on the surface, but they do not know that this is actually the power tool to send you an "SOS signal" : your power tool should be lubrized! If these small problems can not be dealt with in time, it is easy to cause irreversible losses such as increased tool wear and shortened life. Proper lubrication can prevent wear between parts and reduce the number of repairs, thus saving time and cost.
Gear lubrication code
Gear box is the most widely used transmission form in power tools, as one of the most core components of power tools, with high speed, high load, high impact, high temperature and other working characteristics. For gearboxes, if the appropriate lubricant is not used, the harsh working conditions will exacerbate the wear between the gears, which will lead to permanent failure of the gears in the long run.
Switch, contact lubrication code
Traditional power tools are mainly driven by electric wiring, which to a large extent limits the working radius and working conditions of power tools. The battery-powered new generation of cordless power tools are lightweight and portable, expand the scope of operation, improve the working conditions under various application scenarios, therefore, the major power tool brands are competing to launch their own power tool lithium battery platform.
When it comes to the lithium battery working platform, it has to mention the electrical contact, which is one of the important parts of the battery pack and the electrical switch of power tools. The contact point is generally the surface contact between the metal sheet and the metal sheet, and the friction between the metal sheet is more obvious because of the need to slide or touch the metal repeatedly. If there is no lubrication, when the metal sheet is severely worn, it will reduce the electrical conductivity of the contact and affect the actual use effect of the contact.
At the same time, the switch in the current through the state, the metal contact sheet is easy to form an arc, because the arc energy is large, destructive, easy to destroy the contact coating or cause contact ablation, resulting in contact failure, greatly shortening the service life of the contact. Therefore, it is necessary to "tailor" a suitable grease for the switch contacts.
Bearing lubrication code
Bearing is one of the core accessories of power tools, with the development of power tools industry, users of bearing products accuracy, performance, life requirements are becoming higher and higher, and the corresponding lubrication products performance requirements are also constantly improving. The stability and long life of bearing greases under high temperature and high speed conditions are increasingly attracting customers' attention and expectations.
How to choose the right lubrication grease?
1, consider the type and use of tools: different power tools, such as drills, grinders, chainsaws, etc., because of their different mode of operation and load, the demand for lubricating grease is also different. High-speed rotating tools require high-performance lubricants to reduce heat generation, while heavy-duty tools require thicker grease to provide greater lubrication protection.
2, consider environmental factors: the use of the tool environment is also an important factor in the selection of lubricating oils. For example, power tools that work in dusty or humid environments need lubricants with good dust and water resistance.
3, quality and specifications: select the grease specifications specified by the tool manufacturer to ensure that the grease quality meets or exceeds the performance requirements of the tool.
Proper use of lubricating oils is also important. Regular inspection and replacement of grease to ensure that lubricating grease is not contaminated and maintains its optimum performance. Excessive or insufficient lubrication will affect the efficiency and life of the tool.
