Abstract Due to near netshape production, powder metallurgically manufactured (PM) gears have a high potential increase cost and resource efficiency. Compared conventionally machined gears, the advantages of PM are different local density distribution in component integration secondary design elements. These accompanied by reduction weight possibility optimizing NVH-behavior gear. may be both, die pressing additive manufacturing (AM). The bed-based processes for metals can classified into...
In recent years, extensive research has been carried out on the influence of tool and process design wear for bevel gear cutting. However, due to complex interactions between tool, design, an analytical analysis cutting proven difficult. this paper, in continuous manufacturing is analyzed using both simulations trials. Initially, a theoretical performed simulation method derived calculate effective angles. Subsequently, results trials same designs are presented compared results.
On universal milling machines, bevel gears can be produced with standard end mills. Due to the flexible process kinematics, there are fewer restrictions regard implementable component geometries compared conventional gear-cutting processes. The quality requirements for allow deviations of only a few micrometers. For this reason, small production-related lead exceedance permissible tolerances. Furthermore, surface integrity is decisive load-carrying capacity gears. In report, influence on...
During generating gear grinding, a large portion of the energy generated is converted into heat that can flow gear. To better control flowing to gear, an distribution model was developed, which considers chip formation mechanisms each grain grinding worm. The calculation requires knowledge micro-interaction characteristics grains engaging with In this paper, simulation considering during process. Ultimately, performed, contributing
Abstract However, while low pressure carburizing (LPC) is now well established for smaller components and conventional conditions (up to 980 °C), a number of difficulties are expected when considering high temperature LPC large components. First, steels will undergo extensive grain growth during an exposure 1050 °C 20 hours; there solutions avoid the problem shorter durations, no materials adapted such heat-treatment durations. Second, long at means that possibility significant creep...
Zur Steigerung der Zahnflankentragfähigkeit werden Zahnräder vermehrt fein- oder poliergeschliffen. Allerdings existieren bislang keine Erkenntnisse darüber, welchen Einfluss die Prozesse bei gleicher Zahnflankenrauheit auf das Einlaufverhalten von Verzahnungen haben. To increase the load carrying capacity of tooth flanks, gears are increasingly fine- or polish-ground. However, there is hardly any knowledge about how these processes influence running-in behavior with same flank roughness.
