Embodiment Construction

[0020] Provide specific embodiments below in conjunction with accompanying drawings.

[0021] One embodiment of the present invention is that the outer ring [1] is made into a curved arc groove, the inner ring [4] is made into a straight arc groove, and the cage [3] and the inner ring [4] are fixed together to rotate , and make the number of steel balls equal to the number of "peaks" and "valleys" of the curve. The curved groove ball bearing produced in this way is an active swing curved groove ball bearing. In the curved groove ball bearing whose inner ring [4] is a linear groove, the cage [3] can also be made into a structure in a free state, and the curved groove ball bearing with such a structure is a curved groove ball bearing that swings passively. The active oscillating curved groove ball bearing and the passive oscillating curved groove ball bearing are installed in pairs, which can reduce the accuracy required for the installation position.

Abstract

The invention relates to an annular ball bearing device, belongs to the field of general machinery parts, and discloses an annular ball bearing with curved arc grooves, which aims at overcoming the defect of incapability of axial displacement of existing bearings. As for the curved-groove ball bearing, straight arc grooves of a traditional ball bearing are changed into the S-shaped curved arc grooves, so that the displacement of reciprocal rectilinear motion of the bearing can be realized while the bearing rotates. According to the technical scheme, straight grooves of inner and outer rings of an existing bearing are changed into curved grooves which are in full symmetry in shape, the number of peaks and valleys of the curved grooves is the same as that of steel balls or is an integer multiple of that of steel balls, so that during the rotating process of the inner and outer rings, a shaft does periodical reciprocal rectilinear motion while rotating. The curved-groove ball bearing disclosed by the invention has the advantages of being capable of changing rotary motion into rectilinear motion, simplifying the mechanical structure of a rubbing roll and being simple in structure and small in size.

Description

technical field [0001] The invention relates to a centripetal ball bearing device, which belongs to the field of general mechanical parts, in particular to a curved groove ball bearing. Background technique [0002] General-purpose bearings are general-purpose mechanical parts used to position shaft parts so that they can rotate flexibly but cannot produce axial displacement. But for the mechanism that needs to be capable of axial displacement while rotating, such as the movement of squeezing and rubbing rollers, the use of universal bearings will make the mechanism very complicated. [0003] In order to simplify the mechanical structure of the extrusion rubbing roller, and to change the rotary motion into a reciprocating linear motion in a simpler way, the invention discloses a curved groove ball bearing. Contents of the invention [0004] The technical solution for realizing the above invention is to change the original linear grooves of the inner and outer rings of the...
