Как собрать китайскую червячную втулку заднего колеса велосипеда!

Introduction

This tutorial will guide you through the process of assembling a Chinese worm gear hub for a bicycle's rear wheel. Understanding this process is essential for maintaining and upgrading your bicycle, especially if you're looking to replace components for better performance or durability.

Step 1: Gather Your Tools and Materials

Before starting the assembly, ensure you have all necessary tools and materials at hand.

• Tools needed:

  • Wrench set
  • Screwdrivers (flat and Phillips)
  • Pliers
  • Grease or lubricant
  • Clean cloth

• Materials needed:

  • Chinese worm gear hub
  • Bearings (if not pre-installed)
  • Spacers and washers

Tip: Organize your workspace to avoid losing small parts.

Step 2: Prepare the Hub Components

Begin by inspecting all components of the hub.

• Remove any protective packaging.
• Clean the components with a cloth to remove dust or debris.
• Check that all bearings are intact and properly greased.

Common Pitfall: Ensure bearings are not damaged. A damaged bearing can lead to poor performance and a short lifespan for your hub.

Step 3: Install the Bearings

If your worm gear hub does not come with pre-installed bearings, you will need to install them.

1. Apply a small amount of grease into the bearing housing.
2. Carefully insert the bearings into their designated slots.
3. Make sure they sit evenly and are fully seated.

Tip: Use your fingers to press the bearings in gently to avoid damage.

Step 4: Assemble the Hub

Now that the bearings are in place, proceed with the hub assembly.

1. Fit the worm gear onto the hub.
2. Align the spacers and washers as per the assembly diagram (if available).
3. Secure the gear using the appropriate screws or nuts.

Tip: Hand-tighten the screws first, then use the wrench for final tightening. Avoid over-tightening, as this can damage the components.

Step 5: Install the Hub onto the Wheel

With the hub assembled, it’s time to attach it to the wheel.

1. Position the hub in the center of the wheel rim.
2. Align the axle with the dropouts on the bike frame.
3. Tighten the nuts or quick-release lever to secure the hub in place.

Common Pitfall: Ensure that the hub is centered in the wheel to prevent wobbling during rides.

Step 6: Test the Assembly

After installation, it is essential to test the hub.

1. Spin the wheel to check for smooth rotation.
2. Listen for any unusual noises that might indicate misalignment or friction.
3. Check the tightness of all components again to ensure nothing is loose.

Tip: A well-assembled hub should spin freely without any grinding sounds.

Conclusion

Assembling a Chinese worm gear hub for your bicycle rear wheel is a straightforward process if you follow these steps. Always ensure you have the right tools and materials, and take your time with the assembly to avoid common pitfalls. If you're considering further upgrades, look into cartridge-style bottom brackets for improved performance. Happy cycling!
