The most common design solution are cycloidal gearboxes with two discs, in which the reaction forces of bearings from the working discs create a bending moment on the high-speed input shaft, additionally affecting bearings. In the article are presented the results of tests of the cycloid gear prototype with three discs. Instead of the second disc, the introduction of two side discs, 1800 from the centre disc, allows you to reduce this moment to zero. To compensate for the unbalance of the shaft, the side discs have half the width of the centre disc. Each disc works with its own, separate set of bronze rollers, separated by Teflon washers, which should reduce the friction forces. In the article are presented the results of the tests of the cycloid gear prototype determining basic parameters such as efficiency, torque fluctuations on the input and output shaft, housing vibrations in three directions. FFT analysis of registered parameters showed high compliance of the designated frequencies for different measured signals. The assumed advantages, i.e. high efficiency and low vibration level in the tested range, were confirmed. The results are presented in the form of three-dimensional graphs as functions of speed and torque. High efficiency (80-90) % was obtained for load moments above 150 Nm, which is practically independent of the rotational speed with which the cycloid gearing works. The oil temperature during the tests was maintained in the range of 36oC ± 2oC. The maximal torque of the cycloidal gear was 500 Nm.
