Spur Gear Description

Spur gears are cylindrical gears with teeth parallel to the axis, and the teeth are distributed along the busbar direction of the cylinder, which is one of the most basic and common types of gear transmission.

Key Features

Simple structure with low tooth processing difficulty
Generates only radial force during transmission (no axial force)
Stable transmission ratio for accurate constant ratio transmission
Low axial bearing capacity requirements

Working Principle

When the active spur gear rotates, its teeth mesh with the teeth of the driven spur gear in turn, transmitting torque from the driving shaft to the driven shaft through the thrust between the tooth surfaces.

Applications

Ideal for equipment requiring simple transmission structure, including:

Transmission mechanisms in clocks
Power transmission systems in small toys
Transmission parts of household sewing machines
