The structure of the micro gear motor, gear, shaft, bearing are the 12 Volt Motor With Gearbox moving parts, belong to wearing parts, in order to improve the service life of micro gear motor, after years of research and development workers, the study found the scientific use of bearing, can greatly prolong the service life of micro gear motor. Among them, the oil-retaining bearing is the first selection of many tiny reduction motor r&d engineers. Why to choose oil bearing micro gear motor?
1. The role of bearing in micro gear motor: as is known to all, in the process of gear transmission, the shaft and the shaft hole caused by long time friction wear, when the shaft and the positioning hole clearance friction losses caused to a certain degree of gearbox failure or efficiency drops, so we can choose the design of low hardness, good wear resistance materials to do the collar (bearing), thus reducing gear shaft and positioning hole wear, have very good axial positioning effect,
2. The miniature of the gear motor oil bearing materials selection: in the select material of axle sleeve we use brass, bronze, brass + graphite, machining, and such high production and processing cost is only suitable for small batch processing, High Torque 12v Dc Motor usually use powder compacting process mass production, the production cost is relatively low, good consistency and iron base material selection according to product demand, iron, copper, aluminum material for mass production, without cutting, save material, the price is cheap.
3. The miniature of the gear motor oil bearing principle of work: in the process of axle sleeve of powder compacting, in order to reduce the friction coefficient of shaft and shaft sleeve, people developed oil bearing collar to improve the self-lubrication of axle sleeve, it is the use of pressure good body in the sintering process, the characteristic of the porous sintered body to contain a certain amount of lubricating oil, when the axis runtime friction heat in the shaft sleeve, because in oil than metal expansion coefficient is big, so when there will be in the process of heating oil seeping from the shaft sleeve, the attached to the surface of the shaft have the effect of lubrication, when the shaft and shaft sleeve does not work when the temperature drops again, the attached to the surface of the oil will be stored in the back into the shaft sleeve, so the wastage of the axle sleeve of lubricating oil is very small, from the surface to improve the service life of the axle housing.
Machinery, gear lubrication degree is geared to transfer power machinery Vending Machine Motor products, ensure the normal operation of important condition, therefore, we should be attention to its, watch gear lubrication of mechanical products is up to standard, daub on the gear grease, be sure to choose the high quality, suitable grease, the normal transmission of gear at the same time, reduce the pollution to the environment.
Gear lubrication condition is more complex than bearing, load conditions are more demanding. Gear bite for linear contact, contact pressure is high, easy to produce deformation of tooth surface and heat and distorted or distortion phenomena of the shaft. With the development of machinery to high speed, high power, the driving gear, ask its to the durable, small, high torque and high load direction development. Therefore requires proper lubricating oil.
