Characteristics and uses of felt gear

- Nov 19, 2018-

Pure wool felt gear material chooses wool felt produced by imported high-quality wool, which has high density, white and no impurities. It is mainly used for lubricating gears in closed gearbox, so that the gear is always in lubrication state and prolongs its service life. The characteristics of pure wool felt gear transmission are: smooth transmission, accurate transmission ratio, reliable operation, high efficiency, long service life, and wide range of power, speed and size. Different types of gears have different working characteristics. For example, when spur gears are driven, the contact line of the tooth surface is a straight line parallel to the axis, and the meshing of the teeth is contacted or separated along the whole tooth width at the same time, so it is easy to cause impact and noise. In order to overcome this shortcoming, helical teeth, curved teeth, conical curved teeth and hyperbolic teeth are produced to achieve smooth transmission, reduce impact and noise. At the same time, the total length of the contact line of these gears in the meshing area is longer than that of spur gears, and at the same time, several teeth mesh at the same time, and the meshing part is more than that of spur gears, which reduces the specific pressure on the tooth surface, improves the load-carrying capacity of gear transmission, and increases the service life.
