Manufacturing Methods and Materials

Plastic worm gears are an essential component in many mechanical systems. The manufacturing of these components is primarily divided into cutting, heat treating, and grinding after cutting for the worms. For worm wheels, the processes are typically categorized into cutting pearly whites, cutting teeth after casting, and teeth cutting after the outer rim has been cast around the center of the blank.

The materials used for the production of worm gears and worm wheels vary and can significantly affect the performance and durability of the gear. For worm gears, structural carbon steel (S45C, etc.), structural alloy steel (SCM415, etc.), stainless steel, and cast iron are frequently used. For worm wheels, materials include cast iron (FC200, etc.), nonferrous metals such as phosphor bronze and specialty bronze (nickel bronze, aluminum bronze, etc.), and engineering plastics like MC Nylon. The chosen combination of materials for worm gears and wheels significantly influences the allowable transmission pressure and lubrication strategies, requiring careful consideration.

The Role of Lead Angles

Lead angles of a worm’s right and left tooth surfaces are usually identical. However, in duplex worm gears, they are designed to change the tooth thickness of the worm continuously in the axial direction. This allows for adjustment of the backlash by shifting the worm axially with shims.

One of the main benefits of using worm gears is the ability to achieve a significant speed reduction in a compact space compared to using spur gears. Worm gears are typically used to turn the worm wheel. However, when the lead angle is particularly small, the worm wheel cannot turn the worm, a phenomenon known as self-locking. While this can be advantageous in some applications, it is not an efficient preventative measure for reverse driving.

Worm gears also offer additional benefits, such as low noise and vibration. However, due to sliding contact at the tooth surfaces, their efficiency is limited. Furthermore, worm gears can suffer from tooth surface temperature seizure, which is a notable drawback.
