F series parallel shaft gearboxes is a fundamental component of the power transmission system of many types of agricultural machinery.And its output mode is parallel shaft.They are widely used in many industry areas,and there are four basic models of parallel shaft gear reducers, which are: F type, FF type, FAF type, and FA type. In terms of models, from F27 reducer to F157 reducer, the motors with different powers ranging from 0.12KW to 200KW can be matched,superior performance, efficiency up to 95% and more popular.

K series bevel helical gearboxes, manufactured in accordance with international technical requirements, have a high technological content; save space, reliable and durable, high overload capacity, power up to 200KW; low energy consumption, superior performance, reducer efficiency up to 95%. It is easy to install and requires almost no maintenance. Particularly suitable for the field of synchronous control systems and screw jacks.

P series planetary gear units adopts modular design and can be combined according to customer requirements. It is a new type of reducer with wide versatility. The gear units is driven by involute planetary gears, which make rational use of internal and external meshing and power splitting. All gears are carburized and quenched to obtain high hardness and wear-resistant surface. After heat treatment, all gears are grinded, which reduces noise and improves the efficiency and service life of the whole machine. The planetary gear unitshas the characteristics of light weight, small volume, small transmission ratio range, high efficiency, stable operation, low noise and strong adaptability. The gearbox is made of nodular cast iron, which greatly improves the rigidity and shock resistance of the gearbox.

NGW-S series planetary gear reducer is a combination of spiral bevel gear transmission and planetary gear transmission, including two series (S42-S122), three stages (S73-S123) two series of NGW-S planetary gear reducer The design basis of this product is JB3723-84. It is mainly suitable for general mechanical equipments in metallurgy, mining and overweight transport. The maximum speed of the high-speed shaft does not exceed 1500r/min; the peripheral speed of the gear does not exceed 13m/s; the working environment temperature is -40℃-45℃. Cooling measures can be taken to run in both forward and reverse directions. (Forward, clockwise is the preferred direction)

The gear box of the high torque planetary gear reducer is made of high-rigidity materials, which greatly improves the rigidity and impact resistance of the box body, which not only reduces the noise, but also improves the efficiency and service life of the whole machine. The high torque planetary gear reducer has the characteristics of  small size,strong bearing capacity, stable operation, long life, low noise and high efficiency. High-speed shaft speed is less than 1500r/min, gear peripheral speed is not more than 20m/s; ambient temperature is between -40°C~+45°C; both forward and backward operation is possible. Planetary gear units are mainly used in metallurgy, mining,heavy duty, crane transportation, machinery equipment, etc.

NMRV series worm gearbox (aluminum alloy box) is a kind of transmission machinery with compact structure, large transmission ratio and self-locking function under certain conditions. It is one of the most commonly used gearmotors. It is widely used in many industries and fields such as metallurgy, mining, transportation, water conservancy, chemical industry, food, beverage, textile, tobacco, packaging, environmental protection and so on.

The gear and shaft parts of heavy load parallel shaft gear reducers are made of 20CrMnTi and 20CrMnMo alloy steel with high strength, which are carburized, quenched and grinded. Beautiful appearance, convenient installation.The high quality double-layer imported seals and high strength fasteners are used to design the forced circulation system with oil pump. Some models can increase the water cooling system to improve the use power according to the requirements. The product performance has reached the international advanced level.It`s widely used In heavy assembly machinery industry.

Heavy load right angle gear reducer is a relatively precise machine. The gears are all grinded by NC grinding process, with high accuracy, high transmission efficiency, smooth operation and low noise,and its strength and life are much higher than that of the worm gear reducer.In the design of the right angle gear reducer, the gearbox with high strength is adopted, the diameter of the axle is increased, and the bearing with higher bearing capacity is selected, which is suitable for the workplace where the torque requirement is more stringent. And it offers unlimited installation flexibility.

Cycloidal gear reducer is a novel transmission device that uses the principle of planetary transmission and adopts the cycloidal pin tooth meshing, so it is usually also called planetary cycloidal gear reducer. All transmission devices of the cycloid pin gear reducer can be divided into three parts: input part, deceleration part, output part. The machine is divided into horizontal, vertical, double-shaft and direct-connected assembly methods. Its unique stable structure can replace ordinary cylindrical gear reducer and worm gear reducer in many cases. Therefore, the cycloidal gear reducer is widely used in various industries and fields, and is generally welcomed by customers.
