  • What are the advantages of some ground gear it?

    04/24/2011
    Some of the advantages are: hardened and ground gears. 1. noise; 2. maximize efficiency; 3 higher carrying capacity; 4 correction curve of a longer life…
  • When you use a helical gear reducer and the worm reducer?

    04/24/2011
    Worm Reducer is an application for low to medium horsepower. They provide low-cost, high ratio of initial and high output torque in a small package. They have greater tolerance, then the impact load helical gear reducer. Helical gear is used for high-horsepower applications where efficiency is a more long-running important initial investment cost.
  • What's hand drive?

    04/24/2011
    Position of the output shaft of the gear unit relative to its input shaft is referred to as configuration of the hand. This is commonly referred to as right-handers (J), left-handed tendencies (G) or the left and right-handers (H) If the output shaft double extended.
  • What are two main reasons for premature failure of the gear reducer?

    04/24/2011
    Some of the most common causes include failure reducer inappropriate choice for the application, change the motor horsepower or speed, improper arrangement of joints, improper operation or insufficient lubrication, and the lack of regular maintenance and repairs.
  • In the application it is advantageous to use synthetic lubricants gearbox?

    04/24/2011
    Most synthetic lubricants have a lower pour point, high oscillation resistance than conventional petroleum additives accept equivalent. Therefore, a gear box in one of the following conditions, will benefit from the use of synthetic lubricants: hot or cold ambient temperatures; they put heavy burdens; continuous duty; or limited point.
  • Is the worm gear reducer Self-locking?

    04/24/2011
    A worm gear set can not be considered self-locking worm, or irreversible gear. If this condition is established leading insect angle is less than the friction angle, driven by the efficiency of the reverse driving is zero. For under static conditions and other factors will change the angle of friction and surface finish and lubrication. Generally accepted value basis.

Solutions

  • And adding sealant, fasten the screw threaded plug.
  • Scale oil change indicator.
The rapid adoption worm gear tooth surface wear.
  • Overloaded.
  • Does not meet the standard of lubricants.
  • Insufficent Lubricant.
  • Since there is no change in lubricating oil deterioration in time.
  • High temperatures in the running.
  • Adjusted to the appropriate load.
  • Changing a suitable lubricant.
  • According to the scale of lubricating oil index.
  • Changing the oil in accordance with regulations.
  • 1.Processing overheating fault.
  • 2.Take appropriate measures to lower temperatures.
