                    Selection Guides
                    The following information contains the principles of selecting reducers and the correct way to use them.  For the specific value, please refer to the corresponding chapter.
                    Output Torque
                    • 1.1  Rated Torque

                      The value is obtained when the torque acts on the smoothly running reducer and the working coefficient (fs) is equal to 1.

                    • 1.2  Actual Torque

                      Based on the actual needs, this value may be equal to or less than the rated torque (Mn2) of the reducer.

                    • 1.3  Torque Calculation

                      The Calculation of the formula below requires the actual torque(Mr2) and the working coefficient(fs). It is useful when selecting the reducer model.

                    Power
                    • The power (kW) of the reducer in safe operation is listed in the parameter table. They are obtained when the speed is equal to n1, and the working coefficient (fs) is equal to 1.

                    • 2.1 Rated Onput Power

                      The formula below can be used to calculate the output power of the reducer

                    Efficiency
                    • 3.1  Dynamic Efficiency

                      The formula below presents the relationship of dynamic efficiency, output power(p2), and input power(p1)

                    • 3.2  Static Efficiency

                      The efficiency at the start of the reducer. Although it is meaningless for continuous transmission, it is the significant element for selecting the intermittent-transmission reducer. 

                     
                    Joint the world, Drive the futuree
                    Working Coefficient
                    Restrictions
                    Installation
                    The following must be considered when installing the reducer:
                    • 1.Must be installed stably on the machine without any loosening

                      2.Before installing the reducer, checking the rotational direction of the output shaft of the reducer is a requirement

                      3.In the case of long-term storage (4-6 months), once the oil seal is not immersing in the lubricating oil of the reducer, the rubber may stick to the main shaft or even lose its elasticity. Since elasticity is a requirement for a good oil seal, the recommendation is to replace it

                      4.In the case of long-term storage (4-6 months), once the oil seal is not immersing in the lubricating oil of the reducer, the rubber may stick to the main shaft or even lose its elasticity. Since elasticity is a requirement for a good oil seal, the recommendation is to replace it

                      5.Must Avoid the reducer from direct sunlight or exposure to the harsh climate

                      6.Must make sure the good airflow around the motor fan for the adequate cooling

                      7.If the absolute temperature of the reducer when using it is less than 5 Celsius or higher than 40 Celsius, contact our technical staff 

                    • 8.The parts, such as pulleys, gears, couplings, and shafts, must be installed on solid or hollow shafts, and the specialized threaded holes or other tools are required to ensure the installation will not damage the bearings or all parts on the outer end. In addition to that, the lubrication of the contact surface is necessary to avoid sticking or oxidation

                      9.Rubber parts and air vents must not be covered with paint

                      10. When purchasing a reducer with an oil plug, please remove the special plug for transportation and install the exhaust plug

                      11.The oil sight glass has the function of checking whether the amount of lubricating oil is enough or not

                      12.The load of the new reducer should increase gradually, instead of raising up to the maximum load immediately

                      13. If there are any parts, objects, or materials that can leak the oil next to the reducer, then that reducer will need special protection or shielding to avoid damage from the external factors

                    The connection of the motor and PAM flange
                    If you only buy the reducer, you must connect it with the existing motor according to the following suggestions so that the smooth operation of the reducer is assured.
                    • 1.Please refer to the relevant standard to check whether the shaft and flange of the motor have excessive errors during installation。

                      2.Please carefully clean the dirt and dust on surfaces of the shaft, coupling, and flange

                      3.Please install the shaft carefully to ensure the shaft and hole tolerance fits. In addition to that, please avoid the damage caused by excessive force during installation. If it is necessary, use the specialized tools.

                    • 4.Remove glitches ( the position and deviation of the motor keyway should be within the specified range)。

                      5. Lubricate the contact surfaces with lubricating oil to avoid seizing or oxidation。

                    Use and Maintenance of the CVT
                    If you only buy the reducer, you must connect it with the existing motor according to the following suggestions so that the smooth operation of the reducer is assured
                    • 1.The CVT is not for the situations where overload or stall may occur。

                      2.The adjustment is allowed during the operation, and it is strictly forbidden to turn the adjustment handwheel when the CVT stops operating。

                      3.The limit screws at both ends under the operation box have been adjusted. Please do not move。

                      4.The product should not operate in an environment with a temperature higher than 40°C, and the temperature rise should not be higher than 50°C。

                    • 5.The product has already had sufficient lubricating oil before leaving the factory, and the first-time replacement of the lubricating oil should be after the use of 1000 hours. Then every 5000 hours once.

                      6.The lubricating oil in the product should always be two-thirds of the oil level. And the user should check the oil level frequently since it is strictly forbidden to operate in the case of poor lubrication。

                      7.The vent nut on the operation box has been tightened to prevent oil leakage during transportation, and it must be loosened during operation.

                    Lubricating Oil
                    Descriptions of the lubricating oil

                    If you cannot find the corresponding temperature in the table, please contact with our technical staffs

                    If the temperaturee is lower than -30 ℃, or higher than 60 ℃,the specialized oil seal is required

                    If the temperature during oil filling is lower than 0 ℃, the following points must be observed:

                    • 1.The selection of the motor must conform to the surrounding environment and working conditions。

                      2. The starting torque in cold weather is the significant factor for selecting the power of the motor。

                      3.The Reducer with a cast iron gearbox should avoid the sudden heavy shock load, as the cast iron may become brittle at -15°C or below。

                    • 4.At the beginning of use, there might be a problem related to the lubricating oil since the viscosity of the new lubricating oil is relatively high. As a result, operating the reducer for a few minutes under the no-load condition before starting to load is recommended. The replacement of the lubricating oil should be after the first-time use of 10,000 hours, but it also depends on the specific working environment. As for the reducer without the oil fill hole, there is no need to change the lubricating oil。
