Technical Field

[0001] The utility model relates to the field of gears, in particular to a novel special-shaped gear. Background Art

[0002] Special-shaped gears are gears with special shapes. They play an important role in the field of mechanical transmission. Different from traditional circular gears, special-shaped gears have various irregular shapes and can provide precise transmission solutions for various special mechanical needs. The design and manufacture of special-shaped gears require highly professional technology and advanced equipment to ensure that the parameters such as gear tooth shape, tooth direction and tooth pitch meet the requirements, so as to achieve precise transmission.

[0003] Since the force distribution of traditional new special-shaped gears may be uneven during the transmission process, causing certain areas to be subjected to greater stress, thereby accelerating wear and damage, and occupying more space and being heavier, which limits their use in space-constrained or weight-sensitive applications, technical personnel in this field provide a new special-shaped gear to solve the problems raised in the above background technology.
