The world of bevel gear grinding is a complex topic. How do you determine which grinding and dressing parameters to select for a desired surface finish? What type of grinding wheel should be used? What type of dresser should be used? How do all these factors affect the gear noise and quality levels? These are some questions that will be addressed in this article.
On August 23, 2023, India’s Chandrayaan-3 mission made a successful landing on the southern part of the moon near the crater Manzinus. We were able to catch up with Mushtaq
Jamal, vice president of engineering and business development at Bevel Gears India Pvt Ltd (BGI), to discuss BGI's role in this monumental achievement for India.
State of the Gear Industry Perspectives takes an in-depth look at the challenges and opportunities in gear manufacturing today and in the future. Our seventh installment online is an interview with Kika Young, president, and Jared Lyford, director of manufacturing operations at Forest City Gear (FCG).
Since the macro geometry of bevel gears is directly dependent on the manufacturing process, there are limitations in the combination of pre-machining and hard finishing processes which are related to the geometry of the gaps.
One way to implement the growing performance requirements for transmissions is by optimizing the surface finish of the gearing. In addition to increasing the flank load capacity and the transmittable torque, this also allows for improvements in efficiency. On Oerlikon bevel gear grinding machines from Klingelnberg, fine grinding
can be implemented efficiently in bevel gear production - even in an industrial serial process.
In the design process of transmissions, one major criterion is the
resulting noise emission of the powertrain due to gear excitation.
Within the past years, much investigation has shown that the
noise emission can be attributed to quasi-static transmission error.
Therefore, the transmission error can be used for a tooth contact
analysis in the design process, as well as a characteristic value for
quality assurance by experimental inspections.
When Dr. Hermann J. Stadtfeld speaks,
people tend to listen.
Considered one of the world’s foremost
experts on bevel gears, Stadtfeld,
the vice president of bevel gear technology at Gleason, recently revealed several cutting-edge advancements that the company has been working on.
