Plastic gear grease saves plastic gears from wear and tear, slow transmission, etc.

First, the advantages of plastic gears Plastic gears are the key basic components of mechanical equipment products. Plastic and composite gears can replace non-ferrous metal or alloy gears in many cases because of their advantages of light weight, low price, low transmission noise, fewer production processes, and at the same time strength is close to metal gears, and are widely used in industrial manufacturing, such as Plastic gears and special gears are widely used in machinery, instrumentation, telecommunications, household appliances, toy products, energy, transportation and aviation. As long as the equipment is running, the gears do their work. In daily operations, various impurities such as dust adhere to the gears, so that it takes a lot of time and power to rotate the gears. Slowly, the transmission efficiency will be low due to the wear of the gears. In order to solve this problem, plastic gear grease was invented.
2. Plastic gear grease Plastic gear grease is a high-performance white grease refined by thickening extra-high viscosity synthetic oil with lithium soap thickener and adding additives such as anti-oxidation and anti-corrosion. It is used for high requirements on noise reduction and anti-wear. Noise reduction and lubrication of plastic and metal gearboxes. What are the characteristics of plastic gear grease? 1. There is a wide range of working temperature, low temperature starting and running torque are small; 2. Excellent bearing capacity and wear resistance, which can eliminate noise for a long time; 3. Very low friction coefficient, evaporation loss and diffusivity, and good adhesion performance; 4. Excellent oxidation stability, good compatibility with most plastics and elastomers; 5. Good water resistance, shear stability and colloidal stability, and extremely long service life.
3. Selection of plastic gear grease Plastic gear grease is widely used, such as life-long lubrication of plastic gears, bushings, shafts, switches, sliding guides, plastic sliding bearings of electronic equipment, household appliances, toy products, office equipment, disk drives, precision instruments, etc. Muffler. When choosing plastic gear greases in different industries, the following selection criteria need to be carefully considered: When choosing plastic gear grease, the first thing to consider is plastic. The outstanding feature of plastic gear grease is that it can hardly react chemically and physically with plastics, which is a basic performance requirement. The speed of the gear when it is working, taking the small teeth as an example, if the speed is too high to thousands of revolutions, the viscosity of the grease Base Oil will be lower, otherwise it will cause the current to be too large or fly away after one revolution. The temperature range of gears when working, such as low temperature -40°C/-30°C/-20°C, it is necessary to select the base oil with excellent low temperature performance, which will not cause freezing at low temperature. When it comes to gear noise, this cannot be considered solely from the plastic gear grease, because the grease plays a role in assisting noise reduction, and there is also the issue of the precision fit between the gears, because no matter how good the grease is, if the structure between the gears cooperates If the degree is not high, then the effect is not great.
Fourth, the use of plastic gear grease precautions 1. Keep the construction site clean and eliminate dust when using plastic gear grease. 2. Plastic gear grease contains various performance additives, which need to be prevented from contacting with the skin for a long time during use. Wash the skin of your hands promptly after touching plastic gear grease. 3. Do not mix plastic gear greases of different products and brands. 4. The unpackaged plastic gear grease should be used up as soon as possible, and the unused plastic gear grease should not penetrate into other debris when it is stored.
