Abstract
Among the essential issues facing designers of strain wave gears, the provision for correct lubrication should be of paramount importance. The present paper presents the results of research on elasto-hydrodynamic oil film in meshing of a harmonic drive with an involute tooth profile. The research was carried out based on theoretical models developed by Dowson and Higginson. For the discussed structural problem, results of the study are presented graphically in the form of static characteristics of the oil film. Correct operation regimes were determined for two different oils. The paper also provides a review of information concerning the design and principle of operation of strain wave transmission.

IntroductionThe device, equipped with two drives and transmissions providing a reduction rate of 49:1, was designated to support the process of rehabilitation in patients with physical motor disabilities, which made it difficult for them to carry out everyday activities
The results presented in this paper were obtained as part of a wider research project concerning the properties of harmonic drives
This paper presents the algorithm used in the authors’ original model, allowing description of the properties of the oil film in the meshing of a strain wave gear together with results of designed for operation in outer space [30,31];
Summary
The device, equipped with two drives and transmissions providing a reduction rate of 49:1, was designated to support the process of rehabilitation in patients with physical motor disabilities, which made it difficult for them to carry out everyday activities. It is worth mentioning other devices intended for operation in outer space or on other planets [2]. In view of the above, it is advisable to improve and adapt existing transmission designs and develop new ones, capable of meeting the sophisticated requirements demanded from modern drive systems. The following may serve as examples of research projects aimed at the development of existing solutions: Licensee MDPI, Basel, Switzerland
