Three-phase Motor High-speed Reducer Small Engine Gearbox



WP reducer is divided into standard WPS series, standard WPD series, standard WPA, WPO, WPDA, WPDO, WPDS, WPDS, and so on. WP worm gear reducer is developed based on WD reducer. The worm is made of 45# high-quality steel through heat treatment. The worm gear is made of tin bronze, which has good wear resistance, especially on the bearing. The reducer is mainly used in plastics, metallurgy, beverage, mining, lifting transportation, chemical reduction transmission, construction, and other mechanical equipment.


1. The transmission is stable, the vibration, impact, and noise are small, the reduction ratio is large, the versatility is wide, and it can be used with various mechanical equipment.
2. It can be driven in a single stage to obtain a large transmission ratio, and the structure is compact. Most types of reducers have good self-locking properties. The braking requirements of mechanical equipment can save the braking device
3. The meshing friction loss of the worm gear is large, so the transmission efficiency is lower than that of the gear, and it is prone to heat and high temperature.
4. Higher requirements for lubrication and cooling.
5. Good mutual compatibility, worm gears and worms are manufactured according to national standards, and standard parts such as bearings and oil seals.
6. The basic type of box (the box is vertical or horizontal with feet) and general type (the box is cuboid, with fixing screw holes on many sides, no feet or additional feet, etc.). ).
7. There are two connection methods for the input shaft: basic type (single input shaft and double input shaft) and motor flange.
8. The position direction of the output shaft and input shaft is below and above the input shaft; the output shaft is up and down; the input shaft is up and down.
9. Two or three reducer units can form a multi-stage reducer to obtain the maximum transmission ratio.

Small Engine Gearbox

There are many types of gearboxes. These include CVT (continuously variable transmission) and AMT (automatic manual transmission). However, there are several factors to consider before choosing a gearbox.
Gear ratio is an important consideration. The ratio of input gear revolutions to output gear revolutions determines the torque delivered to the wheels. This is important for good fuel economy.
Also, the size of the gears is a factor. Smaller gears will be easier to machine and weigh less. Copper alloys are commonly used for gears, but there are other materials that may be more durable. For example, aluminum alloys are resistant to corrosion and oxidation.
The size of the drivetrain also affects the amount of torque it can produce. Smaller engines tend to have lower power outputs, requiring gearboxes to ensure they can overcome drag at any speed. If they don’t, they stagnate.
Smaller engines are often used in hand-held lawnmowers or concrete mixers. They are also used in small vehicles. Typically, they have an output of less than 15 horsepower.
The CVT transmission is a good choice for city driving. They offer good fuel economy but are not designed for off-road use. Repairing or replacing a CVT transmission can be expensive.
