FIELD: mechanisms with bearings.
SUBSTANCE: present invention relates to mechanisms with bearings operating with axial and torsional loads of various forces, the design of which makes it possible to reduce the torque resistance of the rotation shaft that transmits the external load. A multi-row bearing includes a housing, a rotation shaft, rolling bearings, while the housing contains alternating layers of rotation bodies and balls. The rotation bodies and balls have different diameters, and the space in the housing between the rotation shaft, bearings, rotation bodies and balls is filled with oil.
EFFECT: invention provides the ability to withstand heavy loads, reduce the torque resistance of the rotation shaft and extend the service life of the product, by reducing friction of all structural parts and preventing rust.
