Bicycle Pinion Left Hand Helical Worm Gear For Drive Transmission

The left-hand helical worm gear is famous for its unique spiral design.

●Helix characteristics: The helix of a left-handed helical worm gear rotates counterclockwise. When viewed from the front of the gear, the helix tilts to the left.
●Tooth design: The teeth of the gear are spiral-shaped, starting from one end face and gradually spiraling along the spiral line to the other end face.
●Smooth operation: The helical tooth profile of the helical gear makes the gear mesh more smoothly, helping to reduce noise and vibration.
●Generation of axial force: Due to the spiral tooth shape, the left-hand helical worm gear will generate axial force during the transmission process, making the gear tend to move along the axis direction.
●Load carrying capacity: Helical gears can better withstand side loads, improving reliability when subjected to uneven or impact loads.
●Application fields: Left-hand helical worm gears are often used in cross-shaft gear transmission systems to achieve speed and power transmission.
●Speed ​​ratio conversion: In transmission systems such as transmissions, helical gears are used to achieve conversion of different speed ratios.
●Processing complexity: The processing of left-hand helical worm gears is more complex than spur gears and requires special cutting tools and processing technology.
●Manufacturing accuracy requirements: Helical gears require high manufacturing accuracy to ensure good gear meshing and reduce transmission errors.
