Reducer case of Hangzhou North Depot Workshop-Hangzhou Weigao (WGT) Transmission Machinery

The Hangzhou North Depot of Shanghai Railway Administration is one of the largest freight car depots in my country. With a jurisdiction of 3,500 kilometers, there are nearly 5,000 employees and thousands of employees in different places. Thanks to the meticulous efforts of the staff in this section, nearly 2.2 million cargo wagons received a health "physical examination" every month, and nearly 2,000 cargo trains received maintenance every month.

This section promotes the management concept of "care for cultural people and humanities", lays a solid foundation with safety culture, condenses synergy with family culture, and raises the breeze with clean government culture. Corporate culture stimulates the energy of people’s hearts and promotes a healthy business. Fast development.

Cycloid reducer case of Hangzhou North Depot of Shanghai Railway Administration





Instructions for use


Cycloidal pin gear reducer adopts the principle of cycloidal pin tooth meshing and planetary transmission, so it is usually called planetary cycloid reducer. Planetary cycloidal pin gear reducer can be widely used in petroleum, environmental protection, chemical industry, cement, transportation, In textile, pharmaceutical, food, printing, lifting, mining, metallurgy, construction, power generation and other industries, as a drive or decelerating device, the machine is divided into horizontal, vertical, double-shaft and direct-connected assembly methods. Its unique and stable structure can replace ordinary cylindrical gear reducers and worm gear reducers in many cases. Therefore, planetary cycloid reducers are widely used in various industries and fields and are generally welcomed by users.

Conditions of Use

1. Cycloidal pinwheel reducers are allowed to be used in continuous work situations, while allowing both forward and reverse rotation. Some models of cycloid reducers only allow one-way rotation. 2. The rated speed of the input shaft is 1500 rpm. When the input power is greater than 18.5 kW, it is recommended to use a 6-pole motor with 960 rpm. 3. The working positions of the horizontally installed cycloid reducer are all horizontal. The maximum horizontal tilt angle during installation is generally less than 15°. When it exceeds 15°, other measures should be taken to ensure adequate lubrication and prevent oil leakage. 4. The output shaft of the cycloid reducer cannot be subjected to large axial and radial forces. Other measures must be taken when there is a large axial force and radial force.


1. The horizontal cycloid reducer adopts oil pool lubrication under normal conditions, and the oil level can be kept in the middle of the oil window. When the working conditions are bad and the ambient temperature is high, the circulating lubrication can be used.

2. Cycloid pinwheel reducer generally chooses 40# or 50# mechanical oil lubrication at room temperature. In order to improve the performance of the reducer and extend the service life of the cycloid pinwheel reducer, it is recommended to use 70# or 90# extreme pressure gears. Oil, lubricating oil should be reconsidered when working at high and low temperatures.

3. The vertical installation of planetary cycloid reducer should strictly prevent the oil pump from cutting off the oil to avoid damage to the parts of the reducer.

4. When refueling, you can turn the breather cap on the upper part of the seat to refuel. When draining the oil, turn the drain plug at the bottom of the main seat to drain the dirty oil. There is no lubricating oil inside the reducer when it leaves the factory.

5. New oil should be replaced for 100 hours after the first refueling operation, (and clean the internal dirty oil), then continue to work afterwards, and replace it every six months (8-hour work system). If the working conditions are bad, the oil change time can be appropriately shortened. Practice has proved that frequent cleaning and oil change of the reducer (such as 3-6 months) play an important role in extending the service life of the reducer. Lubricating oil should be replenished frequently during use.

6. The factory-made reducer has been greased and replaced every six months. The grease adopts aluminum disulfide-2# or 2L-2# lithium-based lubricating grease.


  • Where is your product mainly exported?

    Our products are mainly exported to Japan, the United States, Germany, Southeast Asia and other countries and regions. Our customers include many OEM customers specializing in construction machinery. We have partnered with several of the Fortune 500 companies to become one of their major foundry suppliers in China.
