♠ No restriction on motor brand: Match with 15W-200W motor or domestic product available in market without further processing.

♠ Wide reduction ratio: Easily change the reduction ration from 30-20000 due to detached assemble.

♠ May complete with brake,clutch in 1 formation aesthetic and practice.

Main fetures:

1. Large speed ratio range 2. Small volume,low weight ,saving space for mounting. 3. Self-locking

4. High cost performance

5. Suitable for various motors

Use and safety guarantee

1. Please check and confirm the matching intensity between worm gear reducer and mechanical equipment before use to assure that it is in the safety range of worm gear reducer performance parameters
2. Worm gear reducer has filled with WA460 lubricating oil. Please replace the lubricating oil after the first starting of 400 hours and after then 4000 hours for lubricating oil replacing cycle
3. There should be enough lubrication in worm gear box and keep regular check with the oil level.
4. When installation. please be careful to avoid sharp instruments bruising the oil seals on output shaft to cause leakage
5. Please confirm the rotation direction before mechanical connection. If the rotation direction is not correct, it will possible injury or damage the devices
6. Please set safety covers in rotating position to avoid of injuring
7. Please pay full attention: it is very dangerous if there is off or falling when moving

Adjusting Tension on a Mower Gearbox Belt

Proper tension adjustment of the gearbox belt in your mower is crucial for optimal performance and belt longevity. Follow these steps to adjust the tension:

  1. Preparation: Turn off the mower’s engine and disconnect the spark plug wire to ensure safety.
  2. Locate the Adjustment Mechanism: Identify the tension adjustment mechanism on the mower. This could be a tensioning bolt, an adjustable bracket, or another mechanism depending on the mower model.
  3. Loosen Bolts: If your mower has tensioning bolts, slightly loosen the mounting bolts securing the gearbox in place. This allows the gearbox to move and adjust tension.
  4. Adjust Tension: Use the tension adjustment mechanism to increase or decrease the tension on the belt. Refer to your mower’s manual for recommended tension specifications.
  5. Check Tension: After adjusting, check the tension by pressing down on the belt at a midpoint between the pulleys. The belt should give a little, but not excessively. Also, check for proper alignment of the pulleys.
  6. Tighten Bolts: Once the tension is set correctly, tighten the mounting bolts of the gearbox to secure it in place.
  7. Test Operation: Reconnect the spark plug wire and start the mower to observe the belt’s operation. Listen for any unusual noises and monitor the belt for proper engagement with the pulleys.

Regularly checking and adjusting the tension of the gearbox belt ensures efficient power transmission and prevents premature wear. If you’re unsure about the proper tension adjustment, consult your mower’s manual or seek assistance from a professional.

Common Problems with Mower Gearboxes and How to Fix Them

Mower gearboxes can experience various issues over time. Here are some common problems and their potential solutions:

  • Leaking Oil: If you notice oil leaks, inspect the seals and gaskets. Replace any damaged components and refill the gearbox with the appropriate oil.
  • Strange Noises: Unusual noises can indicate worn bearings or gears. Inspect the gearbox for wear and replace any damaged parts.
  • Overheating: Overheating can result from low oil levels or excessive friction. Check the oil level and quality, and ensure proper lubrication.
  • Poor Performance: If the mower gearbox isn’t performing as expected, check for loose belts, misaligned pulleys, or damaged gears. Adjust or replace parts as needed.
  • Slipping Belts: Slipping belts can cause uneven cutting. Check the tension of the belts and adjust them to the manufacturer’s specifications.
  • Lack of Power: If the mower lacks power, check the gearbox and belts for obstructions, and make sure the gears are functioning properly.
  • Vibration: Excessive vibration can result from imbalanced blades or damaged gearbox components. Balance the blades and inspect the gearbox for wear.
  • Stuck Gears: If gears become stuck, check for debris or damage. Clean the gearbox and replace any worn or damaged parts.
  • Worn Bearings: Worn bearings can cause increased friction and noise. Replace worn bearings with new ones to maintain smooth operation.
  • Seized Components: If parts are seized, such as pulleys or shafts, inspect for damage or corrosion. Lubricate or replace components as needed.

For any complex issues or if you’re unsure about repairs, it’s recommended to consult the mower’s manual or seek help from a professional technician or authorized service center.

Signs of a Faulty Mower Gearbox

A faulty mower gearbox can lead to poor performance and potentially expensive repairs if not addressed promptly. Here are some common signs that indicate your mower gearbox may be experiencing issues:

  • Unusual Noises: Grinding, clunking, or squealing noises during operation can indicate worn or damaged gears or bearings in the gearbox.
  • Loss of Power: If your mower is struggling to cut grass or move forward efficiently, it could be due to a gearbox problem affecting power transmission.
  • Difficulty in Shifting Gears: If your mower has a manual transmission, difficulty in shifting gears or gears slipping out of place can be a sign of gearbox trouble.
  • Leaking Oil: Visible oil leaks around the gearbox housing suggest a potential seal or gasket issue that needs attention.
  • Excessive Vibration: Excessive vibration or shaking while operating the mower may indicate misaligned gears or other internal problems within the gearbox.
  • Uneven Cutting: If your mower is leaving uneven patches of grass, it could be due to an issue with the gearbox affecting blade synchronization.
  • Delayed Engagement: A delay between engaging the transmission and movement of the mower can signal a problem with the gearbox’s engagement mechanism.
  • Burning Smell: A burning or overheated odor could be the result of friction caused by damaged or improperly lubricated gearbox components.

If you notice any of these signs, it’s crucial to address the issue promptly. Ignoring gearbox problems can lead to further damage and more expensive repairs down the line. It’s recommended to consult a professional for an accurate diagnosis and appropriate repairs.
