High-Quality China Hard-Toothed Surface Gearbox Speed Reducer from Reliable Suppliers and Factory
⚙ Product Features
- 1 All key design parameters, including the center distance and the nominal transmission ratio, have been thoroughly optimized, and the main components and parts are manufactured with excellent interchangeability to facilitate easy replacement and maintenance.
- 2 Every gear in the system is produced from high-quality alloy steel that undergoes carburizing and quenching heat treatment, resulting in a tooth surface hardness ranging from HRC54 to HRC62 for superior wear resistance and strength.
- 3 This design offers numerous advantages: compact size, low weight, high manufacturing precision, large load-carrying capacity, high operational efficiency, extended service life, outstanding reliability, smooth power transmission, and low noise levels during operation.
- 4 Under normal operating conditions, oil pool lubrication combined with natural cooling is employed; however, when the thermal power rating cannot meet the application requirements, alternative methods such as circulating oil lubrication or cooling assisted by a fan and cooling coil can be adopted.
- 5 The combination of optimized parameters, high-quality gear materials, compact dimensions, and flexible lubrication options ensures that this transmission system delivers dependable, efficient, and long-lasting performance across a wide range of industrial applications.
⚡ Conditions of Use
- 1 The input rotational speed is generally n ≤ 1500 r/min.
- 2 The circumferential speed of gear transmission shall not exceed 20 meters per second.
- 3 Working environment: -40°C to 50°C. If the temperature is below 0°C, the lubricating oil should be preheated to above 0°C 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
- ▶ The first oil change should be performed after the initial 36 hours of operation. This initial change is critical because it removes the metal shavings and fine debris generated during the running-in period, thereby preventing premature wear of the internal components.
- ▶ For subsequent oil changes, the interval depends on the working environment and load conditions. Under normal circumstances, the lubricating oil may be replaced every 2,000 to 5,000 operating hours or every 6 to 12 months, whichever comes first. In harsh environments characterized by high temperatures, excessive dust, or continuous heavy loads, the oil change cycle must be shortened accordingly.
- ▶ The recommended oil change method is to drain the old oil while the reducer is still warm. At this time, the lubricating oil has good fluidity, which allows for more complete drainage. After draining, fresh oil should be added until it reaches the specified oil level indicated on the reducer.
- 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 (FAQ)
Q
What is the maximum input rotational speed this reducer supports?
The input rotational speed is generally n ≤ 1500 r/min. Exceeding this limit may affect gear transmission performance and reduce the service life of the reducer.
Q
What is the recommended tooth surface hardness for the gears?
All gears are manufactured from high-quality alloy steel and undergo carburizing and quenching heat treatment, achieving a tooth surface hardness of HRC54 to HRC62. This ensures superior wear resistance and long-term strength under demanding operating conditions.
Q
How often should the lubricating oil be changed?
The first oil change must be performed after the initial 36 hours of operation. Subsequently, under normal conditions, replace the lubricating oil every 2,000 to 5,000 operating hours or every 6 to 12 months — whichever comes first. In harsh environments (high temperature, heavy dust, or continuous heavy loads), shorten the oil change interval accordingly.
Q
What lubrication methods are available for this reducer?
Under normal operating conditions, oil pool lubrication combined with natural cooling is used. When the thermal power rating is insufficient for the application, alternative methods such as circulating oil lubrication or cooling assisted by a fan and cooling coil can be adopted to maintain optimal operating temperatures.
Q
In what temperature range can this reducer operate?
This reducer is designed for working environments ranging from -40°C to 50°C. If the ambient temperature is below 0°C, the lubricating oil must be preheated to above 0°C before starting the machine to ensure proper lubrication and avoid cold-start damage.
Q
What industries is this reducer suitable for?
This reducer is widely applicable across a broad range of industries, including metallurgy, mining, chemical engineering, building materials, lifting and transportation, textile, papermaking, instruments, plastics, rubber, construction machinery, and energy sectors — making it a versatile and reliable solution for diverse industrial power transmission needs.
