The normal operation, working life and noise level of the micro gear motor are closely related to the characteristics of the lubricating grease. The purpose of using gear grease of gear reducer is different, and the difference of using conditions can be very big.
So, what are the characteristics of the lubricating grease used in the micro gear motor? Next, a brief explanation is given with you.
1、Anti-wear of grease
Anti-wear refers to the oil to maintain the oil film between the moving parts, can effectively prevent the direct contact between the metal ability to add some active substances with sexual molecules in the gear oil can mention its oily, oily agent of the sexual end and the metal surface oxides will produce adsorption, the formation of oily film, oily agent may be with the metal surface oxides to form a metal lubricating film, strengthen the lubricating effect of gear oil, prevent direct tooth surface Contact, reduce friction, reduce wear.
2. Viscosity characteristics of grease
The viscosity of the lubricating oil of the miniature gear motor will decrease with the increase of temperature, the smaller the proportion of decrease, the better the viscosity, the better the viscosity of the lubricant of the gear motor with the temperature change, such as the viscous temperature characteristics of the lubricating grease is not good, then the viscosity of the miniature gear motor will be too big when it starts, not easy to start, so the viscosity of the lubricant of the gear reducer is one of the important characteristics, the viscosity has a great influence on the formation of the oil film, the lubricant can Effectively prevent gear and bearing damage, reduce mechanical operation noise and the risk of oil leakage.
3. Low temperature fluidity of grease
Gear reducer operating in low temperature environment will make the viscosity of lubricating grease rise, can't get effective lubrication, low temperature starting torque increase. So it is necessary to maintain the necessary fluidity at low temperature.
4. Thermal oxidation stability
If the miniature reducer motor works under harsh conditions, under the catalytic effect of air, moisture and metal, the oxidation speed will accelerate the viscosity increase, produce insoluble and corrosive substances and gums, asphaltenes, etc. Add antioxidant in the lubricant to delay the oxidation of lubricant.
5. Anti-rust and anti-corrosion
The anti-rust of the micro gear motor can protect the gear from rust and corrosion and prolong the performance and service life. Micro gear motor in the process of operation, the moisture in the air inevitably condensed into water mist, so the lubricant grease should have anti-rust, such as sulfur salt or fat hydrochloric acid and other anti-rust additives.
