What is Gear 1622002700 wear and tear
Although the application technology of meshing gear set of machine tool transmission is relatively mature, the meshing gear set will wear with the increase of working time, which mainly includes contact fatigue wear of tooth surface and bending fatigue wear of tooth root, which will greatly shorten the service life of the gear.
Impact of temperature on GEAR 1622002700
At present, the lubrication medium used in gear sets has a certain volatility, coupled with the continuous high temperature at work, the lubrication medium will evaporate under high temperature, resulting in the lack of oil in the lubrication system, resulting in insufficient lubrication, resulting in wear and scratches of the gear box gears and bearings, and serious tooth surface gluing and shaft accident. Refer to the chemical frogics of lubricating oil, when the temperature of lubricating oil in the environment of 70℃ or above continuous use, will greatly reduce the viscosity of lubricating oil, and then affect the efficiency of the working room. As a kind of liquid material, the viscosity of lubricating oil is greatly affected by temperature. In general, the viscosity of lubricating oil decreases with the increase of temperature. The boundary lubrication effect has a great influence on the formation of fluid oil film. Boundary lubrication is the relative sliding of the lubricating oil and the gear surface. If the temperature is too high, the efficiency of relative sliding will be reduced, that is to say, the lubricating oil will be like water, which will invisibly aggravate the occurrence of pitting corrosion on the surface of the gear, and then aggravate the occurrence of lubrication failure.
Function of gear:
1.
Transfer the power of mechanical movement: for example, gear shifting devices on automobiles, and industrial reduction boxes, etc., have the function of gears, they can operate normally.
2.
Reduce speed and increase torque: Some motor reducers use gears to control speed.
3.
Change the direction of movement: mechanical watches, electric fans when the presence of gear, can carry out regular operation
