Abstract
The utility model relates to a rod-end joint bearing of an isolating switch, which comprises a sphere, a lining and a shell, wherein the sphere and the lining are provided with spherical-sliding spherical contact surfaces, and the shell is sleeved on the lining. The utility model has the innovation points that a stop is arranged at one end of the inner wall of the shell, and an inner circular-arc surface is arranged at the other end of the inner wall; a structure capable of being embedded with the stop of the shell is arranged at one end of the outer surface of the lining, and an outer circular-arc surface matched and locked with the inner circular-arc surface of the inner wall of the shell is arranged at the other end thereof. The utility model has the advantages that a stop structure is arranged at one end of the inner wall of the shell, and the inner circular-arc surface is arranged at the other end thereof, thus, after the lining is embedded into the shell, one end is blocked by the stop, and the other end is locked by the inner circular-arc surface of the shell to prevent the shell from being separated from the lining in the use process.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of spherical plain bearing rod end of isolating switch.
Background technique
Joint shaft bearing mainly is made up of a spheroid and the lining by inner ball surface by outer spherical surface, can bear radial load, axial load or radially, axial simultaneous joint load, the oscillating motion that the speed that is widely used in is lower, banking motion and rotatablely move.
The spherical plain bearing rod end of isolating switch comprises spheroid and the lining with spherical slip sphere contact surface, and one is enclosed within the shell that has screw-rod structure on the lining.The general interference fit that adopts between its shell and the lining.It exists shortcoming to be: shell and lining in use easily come off, and cause the isolating switch can't proper functioning, have bigger potential safety hazard.
The model utility content
The technical problems to be solved in the utility model provides a kind of isolating switch spherical plain bearing rod end that prevents that lining and shell from coming off.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of spherical plain bearing rod end of isolating switch, comprise spheroid and lining with spherical slip sphere contact surface, and be enclosed within shell on the lining, its innovative point is: described outer casing inner wall one end is provided with stop, and the other end of inwall is an inner arc surface; Described sleeve outer surface one end be can be chimeric with the shell stop structure, the exterior arc surface of the other end for locking with the outer casing inner wall inner arc surface.
Advantage of the present utility model is: mark structure till the end of outer casing inner wall, the other end are inner arc surface, and after lining embedded in the shell like this, an end was blocked by stop, and the other end is pinned by the inner arc surface of shell, prevent in use shell and lining disengaging.
Description of drawings
Accompanying drawing is the spherical plain bearing rod end structural representation of the utility model isolating switch.
Embodiment
As shown in drawings, the utility model relates to a kind of spherical plain bearing rod end of isolating switch, comprises spheroid 2, lining 3, shell 1.
Above-mentioned spheroid 2 and lining 3 have spherical slip sphere contact surface, and spheroid 2 can rotate in lining 3, rotate.Shell 1 inwall one end is provided with stop, and the other end of inwall is an inner arc surface, and lining 3 embeds in the shell 1, and its outer surface one end and shell 1 stop are chimeric, and the other end is an exterior arc surface, and itself and shell 1 inwall inner arc surface lock.
Claims (1)
1. the spherical plain bearing rod end of an isolating switch comprises spheroid and lining with spherical slip sphere contact surface, and is enclosed within the shell on the lining, it is characterized in that: described outer casing inner wall one end is provided with stop, and the other end of inwall is an inner arc surface; Described sleeve outer surface one end be can be chimeric with the shell stop structure, the exterior arc surface of the other end for locking with the outer casing inner wall inner arc surface.
