Helical Gear Shafts

Feida helical gear shafts are mechanical components that integrates the functions of a shaft and a helical gear.Usually,the helical gear teeth are machined directly onto the shaft,which allows the component to serve as a shaft support and transmit power and motion through gear meshing.

The component has a helical tooth design.During operation, the teeth gradually enter and leave the meshing zone rather than engaging across the entire tooth width simultaneously,which helps reduce impact and vibration during transmission,resulting in smoother operation, higher load-bearing capacity , and suitability for high-speed operation.

Technical Specifications

Normal Module (mn): Determines the basic gear size and affects its load-carrying capacity.

Number of Teeth (z): Determines the basic transmission ratio of the gear.

Helix Angle(β): It is one of the most important characteristic parameters of a helical gear.

Normal Pressure Angle(an): The commonly used standard value is 20°.

Pitch Diameter(d): Represents the basic dimensional size of the gear.

Face Width (b): Affects the load-carrying capacity of the gear.

Shaft Diameter(Ds): Determines the load-carrying capacity of the shaft itself.

Rotational Speed (n) and Transmitted Power (P): Used for strength calculations and dimensional design.

Basic Structure and Working Principle

Feida helical gear shaft consists of several sections, including shaft journals, the gear section, shoulders, keyways or splines, chamfers, and other positioning or connection features.

For working principle,This component normally operates together with another helical gear to form a helical cylindrical gear transmission pair.When the driving component rotates, power is transmitted to the driven gear through the meshing of the gear teeth.

How to choose raw materials?

Raw materials need to be matched according to actual usage requirements becuase different customers have different application environments.The common materials include:
