Differences in product definition:
Gears
Gears are a major category, including cylindrical gears, bevel gears, bevel gears, synchronous wheels, sprockets, and other products.
The power and speed range of the transmission are large, and the compact structure can achieve a large transmission ratio, high efficiency, and long service life. It is transmitted through mutual meshing, and the model units are mostly metric, represented by modulus.
Chain wheel
a type of wheel with interlocking teeth, used to mesh with accurately spaced blocks on chain links or cables. There are single row, double row, and multi row options, suitable for low-speed, heavy-duty, and high-temperature conditions. Chain wheels are driven by chains, and the model units are generally in the imperial system.

Differences in product transmission:
Gears can achieve parallel axis and arbitrary staggered axis transmission, which is achieved through the meshing of the wheel path teeth of two gears.
Chain wheels can only achieve parallel shaft backlash, and transmission between two chain wheels must be achieved through a chain.
Differences in product structure:
The gear transmission structure is compact, while the sprocket can achieve long-distance transmission.
Differences in product processing accuracy:
The machining accuracy and installation cost of gears are higher than those of sprockets. Chain wheel is a type of gear, but it does not mesh directly between wheels, but between wheels and a chain, and its processing requirements are relatively low.
Differences in product application characteristics:
When the transmission capacity is limited by space, requiring small center distance, constant instantaneous transmission ratio, or high transmission ratio, extremely high speed, and low noise requirements, the performance of chain transmission is not as good as gear transmission.
Differences in product torque:
Gears transmit more torque than sprockets.
