Three consequences based on the basic law of flat interlocking have been determined that allow generation asymmetric tooth profile different poloidal circles. Gears with are used in both mechanical engineering and measuring devices. Qualitative indicators engagement cannot be accomplished a symmetric developed. A specific example III has presented. The qualitative engagement, which invariant to...

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...

In this paper, the authors present design of a suitable gear transmission with continuously changing ratio in range from 0.5 through 1.0 to 2.0 and back during one revolution intermeshing gears, according demands specified for practical application. The train was designed as pair identical elliptical gears procedure pitch curve (ellipse) is described. center rotation each coincident ellipse foc...

Power skiving is a new gear cutting process that has been recognized to provide step change in the production rate achieved machining of high-precision internal and external involute gears. The based on continuous generating meshing between workgear tool. Understanding loads applied tool, therefore some sources tool wear, have not thoroughly understood. This paper presents novel model able pred...

PURPOSE New devices for IMRT and VMAT QA are continually becoming available. Despite the availability of these devices they are underutilized for routine mechanical QA. In this work we take advantage of the cylindrical geometry of the Arc Check phantom to perform tests that are an integral part of commissioning and routine QA. METHODS The Arc Check is a cylindrical phantom with a diameter of ...

In this study, numerical analysis of a composite spring with nonlinear elastic force-displacement relationship was performed. Due to the lightness and durability materials, their use in automotive industry is increasing production methods allow for high performance design. The behavior pair leaf springs working tandem cross-section profiles be obtained by using involute curve spur gear pairs un...
