Spare parts of speed increasing gearbox case, support base, big gear, transmission axis, bevel wheel and lubrication system.

Technical characteristics
Box is melt with thick steel with great quality to reach the intensity that the case required. Case should take stress aging treatment before the produce to reach the stability that required.
Big gears and gear shaft used carbon alloy steel forging blank, after roughing, workpiece need to take ultrasonic flaw detection process to quench. In order to ensure the tooth surface with high hardness, tooth surface need to take carburizing and quenching treatment after semi-finishing. Fine grind of tooth surface to insure the high accuracy, after finishing the production of gear, the balance test is needed, the experience speed is 1500r/min and the balance level is G2.5.
Transmission shaft use the alloy steel forging blank, transmission shaft takes quenched to make sure the intensity and durableness. After the semi- finishing, transmission need to grind to guarantee the accuracy of every workpiece.
When the assemble finished, the no-loading test should be keep 2-4hours, the speed is 1200r/min, the temperature of shaft should not exceed 60º C, the work of gear should be smooth, no hitting noise and concussion, every joint surface should not have oil spill phenomenon.

Common Problems with Gearboxes and How to Troubleshoot Them

Gearboxes can encounter various issues over time. Here are some common problems and troubleshooting steps:

  1. Noise and Vibration: Excessive noise or vibration may indicate misalignment, worn gears, or insufficient lubrication. Check alignment, inspect gears for wear, and ensure proper lubrication.
  2. Overheating: Overheating can be caused by high friction, inadequate lubrication, or overloading. Verify lubrication levels, reduce loads, and ensure proper ventilation.
  3. Leakage: Oil leaks may result from worn seals or gaskets. Inspect and replace damaged seals, and ensure proper sealing.
  4. Reduced Performance: Decreased performance could be due to worn gears, damaged bearings, or misalignment. Inspect components, replace damaged parts, and realign as needed.
  5. Gear Wear and Tooth Damage: Wear on gear teeth can result from excessive loads or poor lubrication. Replace worn gears and ensure proper lubrication.
  6. Shaft Misalignment: Shaft misalignment can lead to increased wear and noise. Realign shafts using precision measurement tools.
  7. Lubrication Issues: Inadequate or contaminated lubrication can cause premature wear. Regularly check and replace lubricant, and use the correct type for your gearbox.
  8. Bearing Failure: Bearing failure may result from overload, misalignment, or inadequate lubrication. Replace worn bearings and address underlying issues.
  9. Seal Damage: Damaged seals can lead to leaks and contamination. Replace seals and ensure proper installation.
  10. Gearbox Lockup: Gearbox lockup may occur due to foreign objects or damaged components. Disassemble and inspect the gearbox, removing any obstructions and replacing damaged parts.

Regular maintenance, proper lubrication, and timely troubleshooting are key to addressing gearbox problems and ensuring smooth operation.
