Power tool grease selection, twice the result with half the effort!

Many people are vague about the maintenance of power tools, and the wrong grease selection often leads to the shortening of the service life of power tools. I believe that many partners in the operation have encountered power tools temperature rise, abnormal noise, oil leakage and other problems, these problems seem not serious, but they do not know that this is actually power tools to send you an "SOS signal" : your power tools 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.

Electric tool grease is widely used in electric drill, electric hammer, Angle grinder, reciprocating curve saw, cutting machine, grinding machine and other kinds of electric tools, such as electric hammer gear and cylinder, hammer drill gear, and related gear, thread and other parts of lubrication. Although the size of power tools is small, but because of its gear in high-speed, high impact load, lifetime requirements, and a wide variety of power tools, lubrication conditions are very different, there are very demanding requirements for grease.

1.Moderate viscosity and excellent viscosity-temperature function

The viscosity should not be too low, and a certain thick lubricating film should not be produced, but the viscosity should not be too large, so as to prevent the power tool from being easily started at a lower temperature, increasing the risk of damage.

2. Excellent extreme pressure function

For hyperbolic machinery, curved bevel gear and spiral gear, worm gear transmission gear, these are line, point contact, bear a considerable load and a high speed ratio, and not only sliding and rolling, the working condition is particularly harsh, so it must have excellent extreme pressure function.

3. Excellent antioxidant stability

In the process of strong load and high speed operation of machinery, the working environment temperature of gear grease is very high, and it is easy to be oxidized and deteriorated, so the mechanical gear grease needs to have excellent oxidation resistance and stability function at continuous high temperature.

4. It has good anti-corrosion function

In the process of operation of the machine, in view of the function of oxidation and additives, so that the tooth surface corrosion, in the direct participation of water and oxygen mechanical rust corrosion phenomenon, so the mechanical gear grease should have excellent anti-corrosion anti-rust function.

What are the lubrication points of power tools?

1. Gear lubrication

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.

2. Switch, contact lubrication password

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.

3. Bearing lubrication

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.
