Analysis of Two-Stage Cycloid Speed Reducers Dimensions and Efficiency

Abstract

Cycloid speed reducers are characterized by good working characteristics such as very compact design, low level of noise and vibration, wide range of transmission ratios, very reliable operation in conditions of dynamic loads, high level of efficiency, etc. All these listed operating characteristics give them an advantage over conventional speed reducers. Of these good features, the extremely compact design and high efficiency stands out. In this paper, a comparative analysis of the dimensions of a conventional and new concept of two-stage cycloid speed reducer is performed. A comparison was made of the total: length, width, height and volume. A comparative analysis of the efficiency according to the Kudrijavcev method was performed as well. The method of determining the efficiency was adapted so that it could be used in determination in the new concept of a two-stage cycloid speed reducer. At the end of the paper, conclusions are drawn and further directions of research are suggested.
