Spiral Bevel Gear & Gear Shaft Diameter 10mm~1600mm Accuracy Grade 5 Gleason

Product Specification

Spiral Bevel Gear & Gear Shaft (Module 3-20, Diameter 10mm~1600mm, Accuracy Grade 5, Gleason System, Uniform Depth Teeth)

1. Introduction
Spiral Bevel Gears are used to transmit power and motion between intersecting shafts (usually at 90°). Their tooth lines are three-dimensional space curves, ensuring smooth and continuous meshing. The parameters you provided define a category of high-performance, high-precision gear products:

• Wide Size Range: Covers applications from small precision drives (10mm diameter) to heavy-duty equipment (1600mm diameter).

• High Precision Grade:Grade 5 Accuracy is an extremely high precision level, achieved through precision grinding processes. It guarantees exceptionally smooth transmission, very low noise, and precise positioning.

• Gleason System: The world's leading design and manufacturing system for bevel gears. It is a mature and proven technology. The tooth form is Uniform Depth Teeth, meaning the tooth depth remains constant from the toe to the heel of the tooth, offering high strength and long service life.

2. Advantages

• High Efficiency and Smoothness: The spiral tooth curve allows multiple teeth to be in contact simultaneously (high overlap ratio). This results in smoother operation, less vibration, and lower noise compared to straight bevel gears, making them ideal for high-speed applications.

• Exceptional Load Capacity: The large module (up to 20) and the Gleason Uniform Depth Tooth design provide immense tooth root strength and surface durability, enabling the transmission of very high torque and power.

• High Precision and Reliability:Grade 5 Accuracy ensures excellent tooth contact pattern and minimal transmission error. This leads to highly responsive systems, maximized efficiency, minimized heat generation, and superior reliability.

• Optimized Design: The Gleason system provides an optimized tooth contact pattern that can be preset and controlled under load, enhancing service life.

3. Key Technical Parameters (Based on your requirements)

• Module: 3 - 20

• Outer Diameter: 10 mm - 1600 mm

• Accuracy Grade:Grade 5 (According to GB/T 11365 or ISO 17485 standard, signifies ultra-high precision)
