Arrow Gear Company, a global provider of high precision gearing, today announced the introduction of a computer modeling system for use in the design of spur and helical gears. Promising to be the next generation of production technique for precision gearing, Arrow’s system provides a dramatic reduction in lead times, greatly enhances quality and lowers costs to the customer.

This system uses advanced computer technology to predict the performance of a gear before the part is machined. These techniques include Loaded Tooth Contact Analysis (TCA), which is used to determine how the gear will be affected in its actual use under load. In addition, Finite Element Analysis is used to study the physical stresses on the gear under load, thus allowing engineers to modify the design to provide maximum performance.

Notably, Arrow Gear is the first gear company in the world to offer these complete design capabilities in-house.

The benefits to Arrow’s customers from this capability are far reaching. By minimizing the time spent on design and development of a new gear application, the customer saves a great deal of time and expense on upfront costs. In addition, the benefit of bringing a product to market sooner than previously allowed translates to a faster return on new product investment.

This system for spur and helical gears is the most recent expansion of Arrow’s design and development capabilities, which follows a similar system used by the company for spiral and hypoid bevel gears. The development phase of bevel gears is highly involved, however, Arrow’s system has proven to greatly reduce expense to the customer. By eliminating the conventional trial and error process of developing bevel gears, Arrow has been able, in some cases, to reduce development time from six months to less than three weeks. Customers that have taken advantage of Arrow’s advanced bevel design capabilities have conservatively saved $250,000 per gear set in design and development costs.

"It’s important to understand that bevel gear development is much more involved than spur and helicals, and by nature, spur and helical development is not as costly. However, we anticipate that our new design capabilities will translate into a significant impact on cost savings and improved quality for our customers’ spur and helical gear needs," stated Joseph Arvin, Arrow Gear President.
