Jasper Engines & Transmissions prides itself on using quality parts and components. For the remanufacture of axles, American Axle & Manufacturing (AAM) is a key supplier for authentic original equipment parts that include a variety of gears and axle components. In today’s business environment, selecting suppliers depends on a number of critical criteria. AAM provides solutions to many remanufacturers’ performance concerns, including: Cost, Durability, Quietness and Reliability. AAM utilizes advanced manufacturing techniques to exceed the normal performance parameters expected by OEMs.
One such process is a two-cut versus five-cut manufacturing process used for ring and pinion gear sets. Ring and pinion sets are often the cause for vibration, noise and durability problems in axles. A new technology developed by AAM can produce ring and pinion sets that are stronger, more durable and more quiet at a market-competitive cost.
A two-cut process uses no machining oil, compared to conventional gear cutting, making it more environmentally friendly. The two-cut process produces a better performing gear that reduces noise and vibration and increases durability. It improves the tightness of tolerances, therefore allowing fortighter backlash specifications.
AAM cuts ring gears and pinions in one operation, thereby reducing costs. In the manufacturing process, the two components are lapped together after hardening, producing a quiet gear set. Tooth height is measured from root of the gear to the crown. The two-cut tooth is the same height at the toe of the gear, as it is at the heel. This creates a natural “bias” condition, where the pattern shows up slanted when the pattern is rolled with a gear marking compound. This pattern will show more gear mating and less backlash than a conventional five-cut gear.
AAM gear sets are subject to precision shot peening to extend their life. In this process, spherical shot is bombarded to the root of the gear teeth, resulting in comprehensive stresses to combat fatigue loading. Shot peening increases the durability and reliability of the parts.
JASPER chooses to use AAM components for its axle remanufacturing, because AAM provides the same part quality found in the original vehicle products. JASPER and AAM are working hard to provide you, the installing technician, with high-quality products at market-competitive pricing.
