How To Integrate Heat Treatment Into The Spur Gear Manufacturing Process To Improve Performance?

Heat treatment is not a separate post processing step, but a fundamental performance guarantee step that is so closely associated with material selection and processing procedures, which spur gears strength and lifespan are directly determined.

The Purpose of Heat Treatment: From Forming to Strengthening

The heat treatment processes to some extent differ in the emphasis of their treatment:

  • Quenching and Tempering: This process enhances the cores toughness of the gear, thus it allows the gear to be machined easily after this treatment.
  • Carburizing and Quenching: Produces a very hard (58-62 HRC), wear-resistant layer on the gear surface, whilst the core of the gear is kept tough.
  • Nitriding: Enhances surface wear and corrosion resistance without adversely affecting the accuracy.
Heat Treatment Process Applicable Materials Processing Temperature (°C) Holding Time (h) Hardness Range (HRC) Applicable Accuracy Grade (AGMA) Applicable Accuracy Grade (AGMA)
Carburizing and Quenching 20CrMnTi, 20CrNiMo 900-950 2-4 58-62 0.03-0.08 8-12
Nitriding 38CrMoAl, 40Cr 500-550 8-12 50-55 0.005-0.02 10-12
Quenching and Tempering 45# Steel, 40Cr 820-860 1.5-2.5 22-28 0.02-0.05 6-9
Induction Hardening 40Cr, 20Cr 850-900 0.5-1 55-60 0.02-0.06 7-10
Carbonizing and Nitrogenizing 20Cr, 15CrMn 830-880 3-5 56-60 0.025-0.07 8-11

Key Node in Process Integration

The correct process sequence is crucial for ensuring quality. JS Precision's standard process is:

Rough Machining → Tempering → Finish Machining → Carburizing and Quenching → Gear Grinding.

Reversing this sequence is not possible as it will either cause excessive gear deformation or direct scrapping.The gear grinding process is capable of correcting 0.02-0.1mm deformations which may have been caused by heat treatment, thus making sure that the final precision complies with the standards.

Why Is CNC Gear Machining Crucial For High-Precision And Complex Spur Gears?

When it comes to high-precision or complex spur gears, CNC gear machining is the only technology that can be done without convenience. This chapter will focus on the main two advantages of CNC gear machining.

Flexibility and Precision Control

CNC gear machining is capable of producing gear tooth profiles directly from CAD models, thus it is a perfect choice for non-standard tooth profiles, large modules (>10), prototypes, or small-batch production scenarios.

It can reach the dimension accuracy of 0.01mm, thus it can meet the requirements of ISO 1328-1:2013 standards and the tolerance of AGMA 12 precision class are achieved continuously, which are the needs of high-end transmission systems.

Comprehensive Machining Capabilities Beyond Tooth Profiles

Using CNC equipment, machining of all features, such as gear blanks, mounting holes, keyways, and irregular structures, can be done on a single machine tool without relocating the workpiece. This guarantees achieving extremely high-dimensional and positional tolerances, such as coaxiality, and end face runout, which is hardly consistent with traditional special, purpose machines.

How To Choose The Best Gear Manufacturing Techniques Based On Project Requirements?

Choosing the right gear manufacturing techniques is paramount in achieving a balance between precision and cost. JS Precision lays out a decision-making framework that simplifies your choice of an optimum solution.

Process Selection Decision Tree

Choosing a process involves thoroughly evaluating four aspects: type of material, quantity of production, level of precision, and whether there is need for heat treatment.

For example, for steel gears, AGMA Level 9, and medium-batch production, the recommended process combination is "hobbing + shaving". High precision requirements necessitate upgrading to "hobbing + carburizing and quenching + grinding".

Key Process Comparison

Process Type Precision Grade (AGMA) Applicable Batch Unit Cost (USD/piece) Typical Material Heat Treatment Compatibility
CNC Milling 10-12 1-100 15-50 Steel, Aluminum, POM Compatible
Gear Hobbing 6-10 1000+ 2-8 Steel, Cast Iron Compatible
Gear Shaping 6-9 500+ 3-10 Steel, Brass Compatible
Gear Grinding 10-12 500+ 8-20 Alloy Steel Must be compatible

How Do Professional Gear Machining Companies Handle Custom Gear Design?

Excellent gear machining companies are capable of turning customer concepts into producible, high-performance products. JS Precision customizes designs through a three-step process.

Step 1: In-Depth Design Mechanism (DFM)

Engineers examine customer drawings and even go beyond by suggesting tooth root fillet optimization, checking the rationality of tolerances, and giving allowance for heat treatment deformation, thus preventing manufacturing problems from the very beginning.

Step 2: Material and Process Coordination Recommendations

According to the gear's load, speed, and the operating environment, the best material-heat treatment-machining process combination is figured out and recommended. For instance, if there is a high fatigue strength need, the "20CrMnTi carburizing and quenching + gear grinding" solution is suggested.

Step 3: Digital Simulation and Prototype Verification

For the most demanding applications, JS Precision offers Tooth Surface Contact Analysis (TCA) and Finite Element Analysis (FEA) simulation and also a prototype gears manufacturing is done very quickly for the bench testing to verify the design effectiveness.

JS Precision Case Study: AGMA 11 Level Gearbox Gears, From Design Optimization To Mass Production

Challenge: Meeting Extreme Precision and Lifespan Requirements in a Compact Space

A customer was in need of alloy steel gears for a precision gearbox, with a 3 module, requiring AGMA Grade 11 level of precision, a tooth surface hardness of HRC60 or more, and the maximum torque transmission within the diameter restrictions. The original design was susceptible to undercutting, and conventional methods failed to maintain precision requisites constantly.

JS Precision Solution: End-to-End Precision Engineering

1. DFM Optimization:

In the first place, engineers carried out a thorough DFM optimization based on ISO 6336-1996 standards and the knowledge gained from the past similar gearbox cases. We suggested changing the tooth profile features by utilizing micro-tooth tip modification and root fillet optimization.

This way the original design's undercut risk was effectively eliminated, the meshing stress distribution was optimized, the operating noise was reduced, and the grinding allowance of 0.15mm was accurately reserved for the small deformations in the following carburizing and quenching process, thus, the final precision was ensured to meet the standards.

2.Process Route:

Considering gear precision requirements and material properties, the best route was figured out as "precision hobbing carburizing and quenching precision grinding." A German made Klingberg gear grinding machine was imported and core parameters such as grinding speed and feed rate were strictly controlled.

A cooling system was applied for the reduction of thermal deformation, thus making it possible to keep tooth profile and direction error under <0.005mm and fully meeting the AGMA Grade 11 precision standard.

3.Quality Assurance:

A very strict quality control process is being followed from the raw material stage till the final product. Moreover, a 100% online Keyence laser inspection is performed for every single gear, thus tooth profile, tooth direction and runout being some of the parameters thoroughly checked.

Besides, inspection data is simultaneously recorded and SPC statistical process control (SPC) reports are generated to monitor production consistency in real time, thus defective products being prevented from leaving the factory and stable quality in mass production being ensured.

Results

The first prototype arrived within 3 weeks and successfully passed the customer's bench test showing a gear life 30% beyond the design specification. The project thus, made it possible for the successful mass production of 50, 000 units per year with a maintained defect rate less than 0.1%. The customer eventually decided to hand over the entire gear series production to JS Precision.
