Hypoid gear transmission. The size of the super wheel is increased by the offset of the axis, so it can also be used for larger transmission ratios; it is possible to use a through-wheel shaft; due to the additional sliding in the direction of the tooth length, the efficiency is low. Due to the increased risk of gluing, special lubricants are required. However, running smoothness is improved (for automotive transaxles and, more recently, industrial transmissions). www.dwinauto.com

The worm drive can achieve a larger transmission ratio in the first-stage transmission. It must be noted; when i is large, self-locking tends to occur when the force flow is reversed. Due to the large relative sliding of the gear teeth, heat generation is often the determining factor limiting the load-carrying capacity. It is the quietest gear drive and has a high load capacity due to the line contact (as opposed to a cylindrical helical gear drive). When the center distance is not more than 160mm, it is more economical than conical-cylindrical gears. www.dwinauto.com

The worm-spur gear drive is more economical than the single-stage worm drive when the transmission ratio i>40. Due to the high efficiency, when i>10, it has been preferred in some occasions. Under normal circumstances, the first stage , that is, the high-speed stage, is a worm drive, because it has high efficiency and low noise (if it is placed in the second stage, the size will be increased and the price will increase). Exception: In the electric (dynamic) motor reducer, the first stage is a cylindrical gear, in which the shaft is mounted on the motor shaft in a cantilever manner, without a coupling or a separate bearing device. www.dwinauto.com

Helical gears, used for transmission between staggered shafts, each gear is itself a helical cylindrical gear. Due to point contact and sliding along the tooth length, it is only suitable for low power. In special cases, it can also be used for a certain power transfer when the shaft stagger angle is <20°. www.dwinauto.com

The hyperboloid gear transmission is the most common form of gear pair. When the instantaneous helical motion axis (the generatrix) rotates around the wheel 1 axis and the wheel 2 axis on the other hand, their two hyperboloid parent bodies, namely the nodal surface, are formed. The rotational motions of the two hyperboloids around their respective axes can be simultaneously decomposed into a rolling perpendicular to the instantaneous helical motion axis and a sliding along the instantaneous helical motion axis, that is, helical sliding. All gear pairs can be derived from hypoid gears. In this case, the parent compound mode can be replaced by a simpler form:
1) Replace the toroidal throat wheels 1 and 2 with cylindrical helical gears;
2) Wheel 1 and toroidal throat wheel 2 remain unchanged, cylindrical worm drive,
3) Replace the hypoid gear with a hyperboloid gear (staggered shaft spiral bevel gear)
4) The face wheel turns into a round wheel, and there is no sliding along the instantaneous spiral motion axis at this time; www.dwinauto.com
