We utilize the latest and most advanced gear grinding equipment in the industry. Gear grinding offers customers the simultaneous benefits of high material removal rates, superior surface finishes and precise gear geometry.
Superfinishing greatly improves gear tooth surface finish, resulting in efficiency benefits, reduced friction of mating gears, lower energy losses and increased bearing ratio of gear flanks. For a slight cost, our customers can optimize system efficiency and durability by adding superfinishing to existing gear designs.
We have both dry and wet hobbing capabilities. We also have the capability to provide cut or rolled chamfers, which can be processed in parallel to the hob cutting operation to save on cycle time and improve equipment efficiency.
We broach a variety of products and materials, such as internal helical gears for customers on our internal helical CNC controlled broaching equipment. Thanks to our gear expertise, the integration of additional features on customer ring/annulus gears, such as an external park gears, is easily achieved.
Certain complex gear designs may make it impossible to cut external gears with hobbing or internal gears with broaching. In these instances, we can employ our expertise in gear shaping to meet design requirements without any tradeoffs in quality or capability.
As an alternative to gear grinding, we also have the experience to hard finish gears utilizing power honing. Like gear grinding, power honing offers a precise and repeatable process for the post heat treat finishing of gear teeth.
We utilize our equipment and experience to offer a variety of rolled spline options to produce highly precise splines. Even thin-walled spline designs can be accommodated using a variety of steps to incorporate spline rolling into the manufacturing process.
We’ve introduced component level testing to simulate the Noise, Vibration and Harshness (NVH) levels that an individual gear will experience at the system level. Traditionally, this type of testing was only able to be done while the component is assembled at a final transmission test stand. At Systrand, simulated loads are used to mimic the stresses that are on an individual gear and a noise signature is created for that gear. Any anomalies to this noise signature can isolate an issue before a part is shipped to the customer. Furthermore, noise signature data is stored in a database and traced to unique laser marked serial numbers. If a disruption occurs due to a known noise signature, we can trace which serial numbers share that same noise signature and rapidly diagnose and contain a potential issue.
