The helical gear has a transverse force on the opposite axis. In order to eliminate this force, a gear is made into a helical gear with opposite symmetry direction to eliminate this force, which looks like a herringbone. Abbreviated as herringbone gear. The herringbone gear uses the herringbone gear base to transmit the torque of the main motor or motor set to the drum. Herringbone gears cannot be machined by slotting and hobbing.
Extended data:
The main function of the shaft is to support the rotating parts and transmit torque. It is mainly composed of three parts: the shaft section where the hub of the transmission part is installed is called the shaft head, the shaft section matched with the bearing is called the shaft neck, and the part connecting the shaft head and the shaft neck is called the shaft body. The surfaces of the journal and the shaft head are mating surfaces, and the rest are free surfaces. Usually, the diameter of the shaft section of the mating surface should be the standard value, and the corresponding machining accuracy and surface roughness should be determined.
Bearings are components that support the rotation of rotating parts such as shafts and reduce bearing friction. According to the friction form of the relative moving surface, bearings can be divided into rolling bearings and sliding bearings. Commonly used rolling bearings have been standardized and mass-produced by specialized factories, and have been widely used in mechanical equipment.
