Spiral Bevel Gear Design Service

This is a fixed-fee consulting package (NRE) for the complete design of a custom spiral bevel gear set.

Deliverables:

1. 2D drawing file of pinion (driver) and gear (driven) in PDF format
2. 3D CAD file of pinion and gear in STEP format*
3. Ratings, gear forces, and lubrication report
   
4. Review meeting (1 hour) to consult and finalize dimensions

*Teeth shown in the 3D CAD file are for reference only and are not accurate to final manufacturing geometry due to the complexity of gear geometry.

Design Process and Standards:
We apply established gear design practices to ensure optimal performance, reliability, and manufacturability. Based on your exact requirements, we will adjust module, spiral angle, number of teeth, backlash, clearance, contact ratio, and other critical parameters to achieve the smallest possible gear, with maximum performance.

All of our spiral bevel gears include the following standard characteristics:

• Power gears optimized for high-efficiency and low-noise
• Gleason tooth form
  
• Carburized and ground Ni-Cr-Mo Steel
• 90° Axis Angle (intersecting)
• 20° Pressure Angle
• Precision Grade 2 (JIS B 1704:1978)

Note: all of our gear sets are speed-reducing (torque-increasing). The "pinion" is the smaller driver gear, while the "gear" is the larger driven gear.

Interface Selection:
Choose an interface type for both pinion and gear. Interfaces are designed for a minimum shaft yield strength of 800 MPa (through-hardened Cr-Mo steel). Splined bores are stronger than keyed bores, and will result in smaller and stronger shafts.

Spline Manufacturing Cost:
Splines will directly increase the manufacturing cost of the gear due to tooling, or EDM wire cutting. All other interface options are typically lower cost.
