Teeth deformation of non-circular gears

Maláková Silvia

z. 110

105--114

In practice, gear units whose transmission number is not constant during one revolution are used. Such gears include the proposed elliptical transmission. Its application can be (missing a word?) and the automotive industry. The gears set consists of a pair of identical elliptical gears. The transmission ratio of the designed elliptical gear is not constant. The basic kinematic characteristics of this transmission are described in this work. The deformation in contact point of non - circular gears is determined by the finite element method in this paper. The results are compared with the deformation of the teeth of the spur gears.

The Application of Video Method in Research of Uneven Running Strand Transmissions with Cogbelt

Machine Dynamics Problems

2009

Vol. 33, No. 3

42-48

The issue of research of selected phenomena of dynamics and operation during work of uneven running strand transmissions with cogbelt is presented in the paper. Investigations were conducted with the use of high speed camera HighSpeedStar 5. Illustration of designed test stand and preliminary analysis of images, which were obtained during work of uneven running transmission for different rotational speed of gears and variable load conditions, are presented. The developed methodology of research should be helpful during characterization of non-classical coupling process of cogbelt and non-circular cogbelt pulleys. The test results will be used for analysis of performance, manufacturing accuracy of individual components and assembly correctness of uneven running transmissions.
