Replacement Spiral Bevel Gear Set for an Agricultural Gearbox
The drive required a matched spiral bevel pair within module 0.5 to 10 that conformed to specific tooth geometry standards and held gear precision between DIN 3 and DIN 7 after heat treatment.
Customer Pain Points
- Sourcing spiral bevel gears compliant with either GLEASON or KLINGELNBERG cutting systems
- Maintaining gear precision down to DIN 3 to DIN 7 across heat treatment cycles
- Finding an alloy steel gear supplier capable of milling carburizing and finish grinding
- Securing low-volume custom replacement gears cut strictly to customer drawing specifications
Manufacturing Process
- 1
Raw material preparation and blank CNC turning to drawing dimensions
- 2
Spiral bevel tooth milling to GLEASON or KLINGELNBERG gear systems
- 3
Carburizing heat treatment to harden the working tooth flanks
- 4
Tooth grinding to achieve finished gear precision from DIN 3 to DIN 7
- 5
Shaft and bore finishing including grinding to final tolerances
- 6
Final inspection, cleaning, oiling, and packing in crates or cartons
Client Background
An equipment builder in agriculture equipment sourcing a replacement right-angle drive gear set. The client name and commercial terms are not disclosed, so this study describes only the documented technical specifications and manufacturing sequence.
Project Challenge
The drive required a matched spiral bevel pair within module 0.5 to 10 that conformed to specific tooth geometry standards and held gear precision between DIN 3 and DIN 7 after heat treatment.
Our Solution
The spiral bevel gear set was manufactured from specified alloy steel, cut on GLEASON or KLINGELNBERG geometry across module 0.5 to 10, carburized, and finished by tooth grinding to reach the required DIN 3 to DIN 7 precision standard.
Supply Chain Coordination
Alloy steel procurement, gear milling, carburizing, and final tooth grinding were coordinated directly in Hangzhou under ISO 9001 and ISO/TS 16949 quality procedures.
Quality Control
Dimensions were monitored through turning and milling, core and surface hardness were verified after carburizing, and tooth profile accuracy was inspected against the DIN 3 to DIN 7 requirement.
Final Result
A finished spiral bevel gear set manufactured to drawing specifications in module 0.5 to 10, delivering ground tooth surfaces within DIN 3 to DIN 7 precision for agricultural gearbox service.
Customer Benefit
The buyer obtained a replacement gear set manufactured to specific GLEASON or KLINGELNBERG standards, eliminating sourcing issues caused by discontinued parts.
