FAQ
  • Q. What is a gear reducer or gearbox?

    A gear reducer,also commonly know as a gearbox, is a mechanical device used to increase torque while decreasing speed between two rotating shafts. This change in speed-to-torque ratio allows machines to operate more efficiently and safely.

     

  • Q. What are the benefits of using a SGR gear reducer?

    SGR gear reducers are known for their reliability, efficiency, and durability. They offer superior performance and are crafted using cutting-edge technology, which makes them suitable for a wide range of industrial and mechanical applications.

     

  • Q. How shall I select the right gear reducer for my requirements?

    When selecting a gear reducer, consider factors such as the required speed and torque output, the operating environment, and the type of motor or machinery it will be connected to.  You can also directly consult SGR technical expert.

     

  • Q. Can gear reducers be used in high-temperature environments?

    Most gear reducers can handle a range of operating conditions, extremely high temperatures may affect their performance and lifespan. Special high-temperature gear reducers are available for such environments.

     

  • Q. How shall I maintain gear reducer after I buy it from SGR?

    Regular inspection, lubrication, and replacement of worn parts are key to maintaining your speed reducer. SGR provides guidelines for maintenance when you buy gear reducers.

  • Q. What happens if a gear reducer fails?

    Failure of a gear reducer can lead to a reduction in machinery efficiency, excessive noise, and even machinery breakdown. Regular maintenance and inspections can prevent most failures.

  • Q. Where can I buy SGR gear reducers?

    SGR gear reducers can be purchased directly from SGR factory. Request a quote or contact us at any time.

  • Q. How long does a SGR gear reducer last?

    With proper maintenance and under normal operating conditions, SGR gear reducers can last for many years. The exact lifespan depends on usage and environmental factors.

  • Q. Are SGR reducers customizable?

    Yes, SGR offers custom solutions to meet unique operational requirements in different industries. If you need customized reducer solutions, feel free to contact with us.

  • Q. Does SGR have own factory?

    Yes, SGR has its own factory with the area of 15000㎡.

Coaxial Planetary Gear Reducer Industry knowledge

What should be paid attention to when installing and maintaining coaxial planetary gear reducers?

The following key points should be paid attention to when installing and maintaining coaxial planetary gear reducers, and they are explained in combination with the expertise and experience of Shanghai SGR Heavy Industry Machinery Co., Ltd. (hereinafter referred to as SGR):

Installation precautions
Precise alignment:
When installing coaxial planetary gear reducers, ensure that the input and output shafts are precisely aligned with the shafts of the driving and driven equipment. SGR's reducer design focuses on precision manufacturing, and any slight alignment deviation may cause increased vibration and noise, or even damage the gears.

Fixed firmly:
Use appropriate fasteners to fix the reducer to the mounting foundation to ensure its stability and durability. SGR's reducers are generally made of high-strength materials and optimized designs to withstand heavy loads and vibrations.

Lubrication system:
Before installation, check the integrity and cleanliness of the lubrication system. Make sure that the reducer is filled with appropriate lubricants and replaced regularly as recommended by the manufacturer. SGR's reducers are generally equipped with efficient lubrication systems to reduce friction and wear.

Environmental adaptability: Consider factors such as the temperature, humidity, and corrosiveness of the reducer's operating environment. Ensure that the reducer is installed in a dry, well-ventilated environment and avoid exposure to extreme temperatures or corrosive substances.

Maintenance precautions
Regular inspection: Regularly check the operating status of the reducer, including vibration, noise, temperature, etc. SGR's reducer design focuses on reliability and durability, but regular inspections still help to detect potential problems in time and take measures.

Lubrication management: Regularly replace lubricants and clean the lubrication system as recommended by the manufacturer. Using appropriate lubricants can help reduce friction, wear and heat generation, thereby extending the service life of the reducer.

Gear wear inspection: Regularly check the wear of the gears, especially the meshing parts of the planetary gears, sun gears, and inner ring gears. SGR's reducers use high-quality materials and precision manufacturing processes, but wear may still occur after long-term operation. Timely replacement of severely worn gears helps maintain the performance of the reducer.

Sealing performance: Check the sealing performance of the reducer to ensure that there is no leakage. SGR's reducers use advanced sealing technology to prevent lubricant leakage and contaminants from entering. If leakage is found, please replace the seal in time.

Professional training:
SGR recommends professional training for operators and maintenance personnel to ensure that they understand the structure, working principle and maintenance requirements of the reducer. This helps to improve the operating efficiency and reliability of the reducer and reduce downtime.
