Abstract

The article presents a theoretical efficiency calculation of a one stage cycloidal gearbox and its experimental verification on the testing bench. The methodology of numerical calculation is presented in the first part of the article. The gearbox power loss was divided into separate parts, and its presentation on a percentage share plot shows components with the highest influence on the efficiency. A comparison of experimental and theoretical results for different values of the velocity on load is presented in the second part. To be able to compare the results from theoretical calculations with experimental results, all working conditions during the test of the gearbox were set to identical values from calculations, i.e. oil used, the level of the oil, braking torque, input velocities, and constant temperature.
