China DCY Hard-Toothed Surface Gearbox Speed Reducer - Reliable Suppliers & Quality Factory Products
★ Product Features
1
The main parameters such as center distance and nominal transmission ratio have all been optimized in design, and the main components and parts have good interchangeability.
2
All gears are made of high-quality alloy steel through carburizing and quenching, with a tooth surface hardness of HRC54–62.
3
Small in size, light in weight, high in precision, large in load capacity, high in efficiency, long in service life, high in reliability, smooth in transmission and low in noise.
4
Generally, oil pool lubrication and natural cooling are adopted. When the heat power cannot meet the requirements, circulating oil lubrication or fan and cooling coil cooling can be used.
⚙ Conditions of Use
1
The maximum speed of the input shaft of the reducer shall not exceed 1500 r/min.
2
The peripheral speed of the gear shall not exceed 20 m/s.
3
Working environment: -40 to 50℃. If the temperature is below 0℃, the lubricating oil should be preheated to above 0℃ before starting. This reducer can be used for operation in both forward and reverse directions.
4
It can be widely applied in industrial sectors such as metallurgy, mining, chemical engineering, building materials, lifting, transportation, textile, papermaking, instruments, plastics, rubber, construction machinery, and energy.
🔧 Maintenance
1
Regularly check the oil level: Check the oil level once a month or every 500 hours of operation to ensure it is within the specified range.
2
Regularly change the lubricating oil
(1) First oil change: The first oil change should be carried out 36 hours after the first operation to remove the metal shavings produced during the running-in period.
(2) Subsequent oil change: After that, depending on the working environment and load conditions, the lubricating oil can be replaced every 2,000 to 5,000 hours of operation or every 6 to 12 months. In harsh environments (such as high temperatures, much dust, and continuous heavy loads), the oil change cycle should be shortened.
(3) Oil change method: When the reducer is still warm (the lubricating oil has good fluidity), drain the old oil and add new oil to the specified oil level.
3
Keep clean and ensure the vent cap is unobstructed: Regularly clean the oil stains and dust on the surface of the reducer, and inspect and clean the vent cap to prevent blockage.
4
Fastening inspection: Regularly check whether all installation bolts and connecting parts are loose.
5
Abnormal situation handling: Once a sudden increase in noise, intensified vibration, abnormal temperature rise or severe oil leakage is detected, the machine should be stopped immediately for inspection. Operation can only resume after the fault has been eliminated.

❓ Frequently Asked Questions
Q
What is the maximum input shaft speed for the DCY reducer?
The maximum speed of the input shaft of the DCY reducer shall not exceed 1500 r/min. Exceeding this limit may cause overheating, accelerated wear, or mechanical failure.
Q
What working temperature range is the DCY reducer suitable for?
The DCY reducer is designed for working environments ranging from -40℃ to 50℃. If the ambient temperature is below 0℃, the lubricating oil must be preheated to above 0℃ before starting the unit.
Q
How often should the lubricating oil be changed?
The first oil change should be performed 36 hours after initial operation. Subsequently, the oil should be replaced every 2,000 to 5,000 hours of operation or every 6 to 12 months, depending on working conditions. In harsh environments, the interval should be shortened accordingly.
Q
What industries can the DCY reducer be used in?
The DCY reducer is widely applicable across numerous industrial sectors, including metallurgy, mining, chemical engineering, building materials, lifting, transportation, textile, papermaking, plastics, rubber, construction machinery, and energy.
Q
What should I do if abnormal noise or vibration is detected during operation?
If a sudden increase in noise, intensified vibration, abnormal temperature rise, or severe oil leakage is detected, stop the machine immediately for inspection. Do not resume operation until the root cause has been identified and the fault fully resolved.
Q
What type of lubrication and cooling method does the DCY reducer use?
The DCY reducer generally uses oil pool lubrication and natural cooling. When natural cooling cannot meet thermal requirements, circulating oil lubrication or fan and cooling coil cooling can be applied as alternatives.
