What are the advantages of bevel gears in machinery?

  Bevel gears are a kind of gears that are frequently used in machinery. Bevel gears are a kind of more practical gear components. Many times, tasks that are difficult to complete with ordinary gears require this type of bevel gear to complete. The structure of this gear lies in Its shape is of the truncated cone type, with a small upper circle and a large lower circle, and the edge adopts a sawtooth shape, thus forming a so-called bevel gear.

  Bevel gear canReduce the size of the transmission structure and reduce the weight. Under the condition of a certain transmission ratio, when the pinion tooth number zlα is positively transmitted, the contact strength of the tooth surface can be improved. 2. To improve the anti-glue and wear resistance of the tooth surface, adopt a positive transmission with a meshing angle α'>α, and appropriately distribute the modification coefficients xl, x2, so that when the sliding rate of the two gears is equal, the contact stress of the tooth surface can be reduced. It can also reduce the sliding rate between the tooth surfaces to improve the anti-glue and wear resistance of the gear. 3. Matching the center distance When the number of teeth z1 and z2 are unchanged, the meshing angle α'is different, and different center distances can be obtained to achieve the purpose of matching the center distance. 4. In repairing worn-out old gears and gear transmissions, the small gears are more worn and the large gears are lightly worn. You can use negative displacement to cut off the worn parts of the tooth surface of the large gear and reuse it, and refit a positive displacement small gear This saves the material and processing costs required for repair.
