Program: Arrow Gear – Committed to Being the Best


Design Engineering Assistance

Our precision capabilities begin with Design Engineering Assistance.

When a customer requests assistance in the design of gears or gearboxes, we have the expertise to establish all specifications - complete with solid models.

Process Engineering

Next, our Process Engineering Department prepares the routing for the job - complete with each operation that will be involved in the production process. Here, each engineer is equipped with a modular Unigraphics CAD workstation.

Arrow’s Advanced Design and Development Assistance Capabilities

A critical attribute of a spiral bevel gear’s design is its contact pattern. Simply stated, the contact pattern is the area in which the gear teeth come in contact as they engage and disengage during their rotation.

Traditionally, the procedures required to develop a new spiral bevel gear set, with an optimal contact pattern, can require months of trial and error work and thousands of dollars.

To address the traditional limitations of conventional methods, Arrow Gear implemented a highly advanced system for performing contact pattern development – a system that provides a dramatic reduction in the time and expense of the process when compared to conventional methods.

This system uses a combination of state-of-the-art development software and machine tools. Among its key components are Gleason’s G-AGE, CAGE, MINIGAGE, Loaded TCA and Finite Element Analysis software packages. And for machine tools, the system utilizes Gleason Phoenix CNC Tooth Cutters and Phoenix CNC Tooth Grinders, in conjunction with a Zeiss Hofler CNC Gear Inspection System.

Using the development software, engineers can build virtual models to predict how the gear will perform in actual operation. This in turn generates the settings to be used by the machine tools. In addition, these settings for the machine adjustments are automatically downloaded to the machine tools, greatly reducing the time spent on setup.

Perhaps the most dramatic aspect of this system is that ideal settings of the machine tools which are required to produce the desired contact pattern are typically achieved in the first or second attempt.

In essence, this system eliminates the trial and error process that was once required. And the bottom line is that development time is reduced and Arrow is able to provide a significant cost savings to the customer.
