A method profile analytical calculation a disk abrasive tool proposed, providing possibility to grinding wheels for various types ruled helical surfaces: Archimedean, convolute, involute, etc. The use methodology makes it possible achieve high accuracy in processing active (working) side surfaces hardened ...

Large cylindrical worm gear set of ISO type I are manufactured using endmill tools on universal CNC machine tools. This manufacturing method requires neither special gear-generating machines nor The tooth flank forms gears involute helicoids as a standard. targeted theoretical flanks the and mating wheel determined based contact analysis (TCA) such set. cutting conditions after offset distance ...

Reverse engineering plays an important role in the manufacturing and automobile industries designing complicated spare parts, reducing actual production time, allowing for multiple redesign possibilities, including shape alterations, different materials, changes to other significant parameters of component. Using reverse methodology, damaged gears can be identified modeled meticulously. Influen...

Abstract Current challenges for today’s industry are an increase in gear ratio one stage, load capacity as well efficiency compared to standard gears. The tooth profile cylindrical gears is involute. This has certain limits external gearings regarding its geometry, e.g., undercutting and a small radius of curvature near the base circle. Special overcome these offer enormous potential design thr...

Isometric modification is proposed as a new method of axial modification of spur bevel gear. Based on the gear geometry theory and the normal meshing motion equation of gear pairs, changes of meshing points and angles are analyzed and the effect of axial modification on meshing movement of gear pairs is discussed. After that, a method of drawing spherical involute with the aid of SolidWorks sof...

The hypocycloidal flanks of the cylindrical gear teeth have the flank lines defined by lengthened or shortened hypocycloid and the profile involute. The curved and bulged flanks have some advantages, among them being the increased strength in bending and controlled positioning of the contact imprint. The tooth flank generation has on the basis the application of the technological process of mil...

The problem of accurate determination of the position, orientation and width of involute spur gear teeth using a single front-lit image is addressed. The information is used to compute global measures of tooth concentricity and pitch variations across a gear wheel. The approach is based on the use of specialised filters which make maximum use of the grey level information available in the image...

A new form-grinding method of cylindrical involute gears for electrical vehicles (EVs) is proposed to obtain stable contact performance gear tooth surfaces and improve their reliability based on a predesigned controllable second-order transmission error function. The function assigned drive design specifications EVs. Mathematical models modified the pair can be obtained by Moreover, section pro...
