Structure and characteristics of beach bike gears

Source: Zhejiang Jinchi Machinery Co.,Ltd.Release time: 2025-02-25

The gears of a beach buggy are an important component of its transmission system, which transmit power and speed through mutual meshing to drive the buggy forward. The following is a detailed introduction to the structure and characteristics of the gears for beach bikes:

Gear teeth: The gear teeth are the core part of the gear, which have high strength, high hardness, and good wear resistance through precise machining and heat treatment. The shape and size of the gear teeth are designed according to the requirements of transmission ratio and torque.

Central axis: Each gear has a central axis, and the meshing between gears occurs between two central axes. The position and angle of the central axis have a significant impact on the transmission efficiency and stability of gears.

Material: Beach bike gears are usually made of high-strength, high hardness alloy steel or stainless steel to ensure good wear resistance and impact resistance.

Lubrication and cooling: In order to reduce friction and wear between gears and improve transmission efficiency, beach bike gears usually require lubrication. At the same time, lubrication can also play a cooling role, preventing gears from being damaged due to overheating.

Beach bike gears are an important component of the transmission system of beach bikes. Through precise processing and heat treatment, they have high strength, high hardness, and good wear resistance.
