Research of modified gear drive for multioperational machine with increased load capacity

Krol Oleg, Sokolov Volodymyr

Diagnostyka

2020

Vol. 21, No. 3

87--93

The presented work is devoted to the improvement of spur gears of the reduction drive for metal-cutting machines according to the criterion of load capacity. A feature of this article is the creation of such a constructive solution, which is aimed at finding a compromise between reducing contact loads in the engagement zone and increasing the complexity and labour intensity of the manufacturing gears process. A procedure for accelerated creation of 3D models of a gear drive and its components using the specialized software application “Shafts and Mechanical Transmissions-3D” in the environment of integrated CAD system KOMPAS-3D is proposed. A study of a new cylindrical gear transmission design with a longitudinal generatrix of axoids, confirmed by the corresponding patent solution is realized. A calculation form for the practical design and manufacture of a new design cylindrical gear is proposed.

Theoretical estimate method for cylindrical gearing contact and wear

Kozhina T.D., Zamyatin J.P.

Tribologia

2006

nr 4

77-86

The algorithm of the parameter calculation of macro-geometry, kinematics, macro- and micro-contacting, wear rate as well as those of frictional resource of cylindrical gearings with external evolvent toothing are presented. The most widely used in aircraft engine external toothing cylindrical gearings with evolvent tooth profile and transition curve with undercut are regarded as subject of inquiry.

W artykule opisano algorytm obliczania parametrów kinematycznych, mikrogeometrycznych, mikrokontaktów oraz wielkości zużycia w odniesieniu do walcowych przekładni zębatych z zazębieniem o zarysie ewolwentowym.
