27 teeth single groove gear bevel shape

Unlike the helical bevel Gear where the helical angle of the main and driven gears is equal due to the intersection of the axis of the gear pair, the axis offset of the hypoid gear pair makes the helix angle of the active gear greater than the helix angle of the driven gear. Therefore, although the normal modulus of the hypoid bevel gear pair is equal, the end face modulus is not equal (the end face module of the active gear is greater than the end face module of the driven gear). This allows the active gears of the quasi-double-sided bevel gear transmission to have a larger diameter and better strength and stiffness than the corresponding helical bevel gear driven active gear. In addition, due to the large diameter and helix angle of the active gear of hypoid bevel gear transmission, the contact stress of the tooth surface is reduced and the life is improved.
However, the transmission is relatively small, and the active gear of the quasi-double-sided bevel gear transmission is too large compared to the active gear of the helical bevel gear, so it is more reasonable to choose the helical bevel gear.

In addition, we have other accessories such as Circular machine oiler, Control Panel, Adjustable Yarn Bobbin Cover, Synchronous Belt, Needle Cylinder and so on.
