Abstract In this paper the generalized model of contact two plan bodies that roll and slide or just is presented. The analytical solution correct distribution pressure in realized presence normal compressive force, which realizes contact, as well force pair a tangential force. This can be used on sprocket teeth due to sliding rolling itself gear pole. results obtained have been experimentally c...

The computer program GearKURT has been created to calculate mechanical gears. allows you gears:
 - closed cylindrical spur gear
 helical open Novikov's bevel gear with indirect teeth
 worm-gear.
 a dialog interface written in the object-oriented programming language Delphi and compiled into an exe-file. choose necessary material method of heat treatment for manufacture gears...

Gearboxes sustain a variety of faults such as broken-shafts, eroded, broken, or missing teeth, and even broken-cases. Casing mounted accelerometers can detect fault patterns but the signals are complicated and difficult to interpret. This study considers the tooth loading of ideal gears and gears with defects. A large industrial gearbox used in a 12m electric mining shovel is modeled. The nonli...
