What's the meaning of gear?
Classification: according to the relative position of the two shafts, the gears can be divided into the following three categories:Cylindrical gear (spur gear) - used for transmission between two parallel shaftsBevel gear ---- used for the rotation between two intersecting pointsWorm gear - used for the rotation between two vertical cross shafts
The main function: transmit power, change the speed and direction of movement.The working principle is to transfer the motion and power by meshing the teeth with the links.Advantages: 1: high transmission efficiency; 2: large transmission ratio; 3: transmission torque; 4: long life.Disadvantages: 1: heavy weight; 2: noise; 3: transmission distance is small; 4: the need for regular lubrication.
Gear: a mechanical element with teeth on the flange that continuously engages and transmits motion and power. Gear is the mechanical parts that can mesh with each other. The application of gears in transmission has appeared very early. At the end of the nineteenth Century, the principle of expanding the cutting method and the special machine tools and cutting tools used in the cutting of the teeth were presented one after another. With the development of production, the stability of gear operation has been paid attention to.
