In order to verify the kinematic model, during the gear hobbing test, the position track of the cylindrical gear is collected through the Siemens 840D system of the gear hobbing CNC machine tool. The technological parameters of cylindrical gear hobbing test are shown in the table. Parameters Specifications Module...
Introduction Currently, the modified straight bevel gears are widely used in machine tools and other equipment, as well as in vehicle differentialIt is widely used in automotive components such as transmissions.Features such as contact areas and contact patterns can visually reflect the gearTo optimize the design of the modified...
High-speed dry hobbing is a new technology for gear machining,It is an efficient manufacturing process for machining spur and helical gears.However,High-speed (spindle speed 1200r/min) cutting speed fluctuation is large, especially for helical gear machining, which requires two sets of electronic gearboxes for multi-axis synchronous control.Therefore, the machining error compensation...
Take spur gear as an example to analyze hobbing kinematics, as shown in the figure. Hob (cutter) and spur gear (workpiece) rotate around its axis at angular speed ω C and ω G Synchronous rotation. The hob feeds along the width of the spur gear at the axial feed...
