CYCLOIDAL REDUCTION GEAR Russian patent published in 2024 - IPC F16H1/32 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in machine building and robotics as actuators, particularly in robotics, for example, a knee mechanism, and processing machines, for example, additional axes, in aviation equipment and navigation systems, medical equipment and rotary manipulator tables, in handling and transport equipment, and can be used as a high-precision drive with simultaneous transmission of high power, as well as a high-precision rotary support mechanism. Cycloidal reduction gear comprises a housing, in the support bearings of which there are rigidly interconnected rotary flanges, a central input shaft installed in the bearing supports of the flanges, teeth-rollers, freely installed in recesses of the housing and being in constant engagement and interaction with epicycloidal teeth of impellers-satellites, located with eccentricity in the housing and located in the drive unit and representing a unit of impellers-satellites, which is made of at least three impellers-satellites, and the drive assembly contains the bearing eccentric rings, which separate the impellers-satellites from each other, between which the bearing rollers are installed parallel to the input shaft at the height of the impeller, the inner cage of bearing is made in the form of the input shaft eccentric, and the outer cage is made in the form of the central hole of the impeller-satellite, at that the support bearings are made as conical roller ones, and the flanges are tightened to each other by pins.

EFFECT: invention provides creation of a backlash-free reduction gear with increased load capacity and increased service life due to the use of the third impeller-satellite, and this, in its turn, contributes to increase of kinematic accuracy, moment capacity and rigidity of reduction gear.
