JR Series Helical Gear Reducer Manufacturers

How to choose the right JR Series Helical Gear Reducer?

Selecting the right JR Series Helical Gear Reducer requires consideration of several factors to ensure performance and suitability. Here are some key steps and considerations:

1. Determine application requirements
Load type: Determine whether your application is constant load, shock load, or cyclic load.
Working environment: Consider the temperature, humidity, dust, and other contaminants of the working environment, which may affect the choice of reducer.

2. Calculate torque and speed
Input speed: Determine the input speed of the motor, usually in RPM (revolutions per minute).
Required output torque: Calculate the required output torque based on the application requirements, which will directly affect the choice of reducer.

3. Select reduction ratio
Reduction ratio: Calculate the reduction ratio based on the required output speed and input speed to ensure that the selected reducer can provide the required speed reduction.
Efficiency: Different reduction ratios will affect efficiency, and the balance between efficiency and reduction ratio should be considered when selecting.

4. Check size and installation space
Physical size: Measure the available installation space to ensure that the selected reducer fits the space requirements of the equipment.
Installation method: Select the appropriate installation method (such as base installation, flange installation, etc.) according to actual needs.

5. Consider load characteristics
Starting and braking conditions: Consider the starting and braking methods of the equipment and select a reducer that can withstand these conditions.
Frequency of use: Evaluate the frequency of use of the reducer to determine its working intensity and durability requirements.

6. Determine the lubrication method
Lubrication method: Select the appropriate lubrication method (such as oil lubrication, grease lubrication) to ensure the normal operation and life of the reducer.

What are the common faults of JR Series Helical Gear Reducer?

JR Series Helical Gear Reducer may encounter some common faults during use. Understanding these faults and their causes can help us take timely measures for maintenance and repair. Here are some common faults and their possible causes:

1. Excessive noise
Reason:
Poor gear meshing: It may be caused by improper installation or inaccurate shaft alignment.
Poor lubrication: Insufficient lubricant or poor quality lubricant may increase friction, resulting in noise.
Gear wear: Wear or damage to the gears can cause poor meshing and produce abnormal noise.

2. Overheating
Reason:
Insufficient lubrication: Lack of proper lubricant or dirty lubricant will cause increased friction and overheating.
Overload operation: The equipment works beyond its rated load, increasing the heat of the reducer.
Poor heat dissipation: The installation location of the reducer is poorly ventilated and the heat dissipation is poor.

3. The output shaft does not rotate
Reason:
Motor failure: There is a problem with the motor itself, resulting in the inability to provide input rotation.
Gear jamming: The internal gears may not operate properly due to wear or foreign matter stuck.
Transmission component breakage: If the coupling or other connecting parts are broken, the output shaft cannot rotate.

4. Abnormal vibration
Reason:
Improper shaft alignment: If the shafts of the reducer and motor are not aligned, vibration may occur.
Unbalanced load: Uneven load distribution can cause the reducer to vibrate during operation.
Gear wear: Uneven gear wear can also cause vibration.

5. Oil leakage
Reason:
Damaged seal: Aging or damage to the reducer seal can cause lubricating oil leakage.
Improper installation: Failure to follow the specifications during installation leads to poor sealing.
Excessive lubricating oil pressure: Excessive internal pressure may cause oil seal failure.

6. Insufficient power
Reason:
Load exceeds the rated value: The rated power of the reducer is exceeded during use, resulting in performance degradation.
Gear wear: Wear or damage to the gears will reduce the output torque.
Inappropriate selection: The selected reducer is not suitable for the actual load, resulting in the inability to provide the required power.

7. Frequent tripping of overload protection
Reasons:
Abnormal load: The equipment load is too large, exceeding the load capacity of the reducer.
Poor gear meshing: Improper gear clearance increases friction.
Motor failure: Problems with the motor itself lead to insufficient power or difficulty in starting.

Maintenance recommendations
For the above common faults, it is recommended to take the following maintenance measures:
Regularly check and replace lubricating oil to maintain good lubrication.
Regularly check the gear meshing to ensure accurate installation.
Monitor the working temperature and noise, and deal with abnormalities in time.
Perform regular maintenance and maintenance to ensure that the reducer operates in good working condition.
