Force bearing device based on annularly-distributed multistage bearing

Abstract

The invention provides a force bearing device based on an annularly-distributed multistage bearing and belongs to the technical field of mechanical engineering. In the device, an M-class bearing comprises K (M-1)-class bearings and objects A' and B' which are connected with the M-class bearing and can rotate relative to each other, the object A' is taken as an inner ring of the M-class bearing, and the object B' is taken as an outer ring of the M-class bearing; the K (M-1)-class bearings are uniformly and annularly distributed between the outer ring and inner ring of the M-class bearing, the inner rings of the K (M-1)-class bearings are fixedly connected with the inner ring of the M-class bearing by virtue of studs, the outer rings of the K (M-1)-class bearings are contacted with the inside orbit of the outer ring of the M-class bearing, and K is an integer greater than 2, and M=2,3,.....N. By virtue of the force bearing device of the multistage bearing, the two objects which can rotate relative to each other are directly taken as the inner ring and the outer ring, the volume and weight of the whole force bearing device are greatly reduced, and the objects such as cables are distributed in the middle hollow part of the inner ring of the multistage bearing in a passing manner.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and in particular relates to a load-bearing device based on an annular distributed multistage bearing. Background technique [0002] Bearings are fixed parts in machinery. When other parts move relative to each other on the shaft, the bearings are used to reduce the friction coefficient during power transmission and keep the center of the shaft fixed. From heavy-duty wheel axles and machine tool spindles to precision watch parts, bearings are needed in many occasions. It can be said that bearings are important basic components of various mechanical equipment. [0003] In the traditional technology, the connection and relative rotation of two objects A and B are realized through bearings. Object A cooperates with the inner ring of the bearing, and object B cooperates with the outer ring of the bearing. The size of the bearing needs to be set according to the bearing force brought b...
