Gear：Is the use of gear teeth of two gears meshing each other transmission of mechanical power transmission and sport. According to the relative position of the gear axis parallel to axis of cylindrical sub-gear drive, bevel gear axis intersect and cross-axis helical drive gear. Compact structure, high efficiency, long life and so on.
Gear refers to the main, driven wheel gear direct, transfer and exercise of the power devices.
Of all the mechanical transmission, the most widely used gear can be used to transfer between any two-axle and exercise power.
The characteristics of gear is: a smooth gear transmission, the transmission ratio accurate, reliable, high efficiency, long life, the use of power, speed and size range. Such as transmission of power from small to almost 100,000 kilowatts; speeds of up to 300m / s; gear diameter from a few millimeters to more than 20 meters. However, the need for specialized gear manufacturing equipment, the meshing noise transmission.
Many types of gear.
(1)According to the relat辣'文-论"文~网http://www.751com.cn ive positions of the two-axis and the direction of the tooth can be divided into the following types:
<1> column <3>;
<2> bevel gear drive;
<3> cross-axis helical gear drive.
(2)According to the working conditions of gears can be divided into:
<1>-type open gear drive gear drive, gear exposed, does not guarantee good lubrication.
<2> semi-open gear drives, gear oil immersion pool, has shields, but not closed.
<3> closed gear transmission, gear, shaft and bearings are installed in the closed, good lubricating conditions, Sha easy access, installation of precision。
