The genesis of HomeAway, Inc. was startup by accretion – eight companies in the web-based vacation home rental market were acquired and merged. The technical solution during the merger and acquisition phase was to assimilate the software functionality of each of the eight companies into a one-size-fits-all application that could be configured with runtime settings to support the look-andfeel of...

Time for a Change For many years, the U.S. system of gear accuracy tolerances has been provided by AGMA 2000-A88, Gear Classification and Inspection Handbook. This document has been commonly used for gear accuracy specifications in contractual agreements for vendor-supplied gears. Also, it has often been used as the basis of internal company gear tolerance systems. The material within AGMA 2000...

A method is presented that allows the accurate measurement of the tooth pair stiVness of a pair of spur gears. The method reveals the stiVness behaviour throughout the full length of the normal path of contact and also into the extended contact region when tooth corner contact occurs. The method makes use of the properties of transmission error plots for mean and alternating components over a r...

The paper presents the methodology of modelling tooth flanks of cylindrical gears in the CAD environment. The modelling consists in a computer simulation of gear generation. A model of tooth flanks is an envelope curve of a family of envelopes that originate from the rolling motion of a solid tool model in relation to a solid model of the cylindrical gear. The surface stereometry and topography...
