Customized C45 Sprocket Gear for Heavy-Duty Industrial Machinery

Product Description

Welcome to Star Machinery!

Product Description

Type A spur gears are straight cylindrical gears conforming to a specific tooth profile standard specified in the Chinese national standard (GB/T). Their tooth lines are straight lines parallel to the gear axis. Type A spur gears are typically flat, meaning the gear body is a solid disc without a protruding hub (usually there is a hole in the center for mounting a shaft). The overall thickness of the gear is relatively uniform, and its tooth profile is a standard involute tooth profile with a high tooth tip and a shallow tooth root.

Comparison of Type A and Type B Gears

Characteristics	Type A Gear (Type A Spur Gear)	Type B Gear (Type B Spur Gear)
Tooth Tip Height	Higher (ha* = 1.0)	Shorter (ha* = 0.8)
Tooth Root	Relatively Shallow	Relatively Deep
Clearance	Smaller (c* = 0.25)	Larger (c* = 0.3)
Features	Slightly higher contact ratio, smoother transmission. Relatively weaker tooth root strength.	Higher tooth root strength, stronger bending resistance. A larger clearance facilitates oil storage and lubrication, making it suitable for high-speed, heavy-load applications.
Applications	Most commonly used in general operating conditions  and standard transmissions.	Often used in applications with special requirements for tooth root strength,  lubrication, or thermal expansion, such as heavy machinery and high-speed gearboxes.

Summary:"Type A spur gears" are the most commonly used spur gears that conform to Chinese national standards and use standard addendum and clearance. In most general mechanical transmission designs without special requirements, Type A spur gears are the default choice unless otherwise specified, and are used in various general industrial machinery.
