Abstract

The utility model relates to a bearing which comprises a bearing outer ring, a bearing inner ring and a steel ball, wherein grooves are arranged at the upper edge and the lower edge of the bearing outer ring; the maximum diameter of the lower end of the bearing inner ring is equal to the diameter of the outer wall of the bearing outer ring, the maximum diameter of the upper end of the bearing inner ring is equal to the diameter of the inner wall of the bearing outer ring, the edge of the upper end of the bearing inner ring is arc-shaped, protrusions are arranged among the arc-shaped edges, and arc-shaped smooth grooves are evenly arranged on the outer wall of the bearing inner ring; and the steel ball is inlaid in the grooves of the bearing outer ring and pushes against the arc-shaped smooth grooves of the bearing inner ring. By adoption of the structure, the steel ball can slide flexibly without falling off easily, thereby lowering the installation and maintenance cost.

Description

A kind of bearing

Technical field

The utility model relates to a kind of bearing of mechanical field, especially a kind of bearing of difficult drop-off again that slides flexibly.

Background technique

Bearing is mechanical field a kind of component commonly used, is mainly used in support and location to some transmission paries, but bearing now often comes off easily, and it is also dumb to slide, in use usually can increase installation and maintenance cost.

Summary of the invention

The utility model provides a kind of bearing of difficult drop-off again that slides flexibly to the deficiency of existing technology.

The utility model is realized through following technological scheme:

A kind of bearing comprises bearing outer ring, bearing inner race and steel ball, it is characterized in that: the bottom and upper segment of said bearing outer ring evenly is provided with groove; The maximum diameter of said bearing inner race lower end equates that with the bearing outer ring outer diameter maximum diameter of bearing inner race upper end equates with the bearing outer ring inner diameter, evenly is provided with the smooth groove of arc line type on the outer wall of said bearing inner race; Said steel ball is set on the groove of bearing outer ring and offsets with the arc line type smooth groove of bearing inner race.

Further, the groove on the said bearing outer ring is few positive groove on one side.

Further, the bottom and upper segment of said bearing outer ring is provided with the same number of groove.

Further, the slot number of the bottom and upper segment of said bearing outer ring is 12 altogether.

Further, the edge of said bearing inner race upper end is an arc line type, and the projection corresponding with the bearing outer ring groove arranged between the camber line edge.

Further, the groove on the said bearing inner race evenly respectively is located on the upper wall and lower wall of the bearing inner race outer wall corresponding with the groove of bearing outer ring.

The beneficial effect of the utility model is: nationality is rolled on the groove at bearing inner race under the effect of bearing outer ring groove to support and the location transmission part by steel ball, makes bearing more firm like this, uses more flexible.

Description of drawings

Fig. 1 is the schematic representation of bearing outer ring;

Fig. 2 is the schematic representation of bearing inner race;

Fig. 3 is the schematic representation that bearing outer ring and bearing inner race combine.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

From Fig. 1, Fig. 2 and Fig. 3, can find out; The utility model comprises bearing outer ring 2, bearing inner race 1 and steel ball 5; The bottom and upper segment of bearing outer ring 2 evenly is provided with 12 positive grooves 4 altogether; There is arc line type edge 6 outer wall 11 upper ends of bearing inner race 1; Projection 7 is alternate with arc line type edge 6, and groove on the bearing inner race 13 evenly respectively is located on the upper wall and lower wall of bearing inner race 1 outer wall 11 corresponding with the groove of bearing outer ring 24, and steel ball 5 is set on the groove 4 of bearing outer ring 2 and offsets with the arc line type smooth groove 3 of bearing inner race 1.From Fig. 1, Fig. 2 and Fig. 3, can find out; On the groove 4 through steel ball 5 edge and bearing outer ring 2 and the groove 3 of bearing inner race 1; Combine bearing outer ring 2 and bearing inner race 1, when bearing in the running, nationality is rolled on the groove 3 at bearing inner race 1 under the effect of bearing outer ring 2 grooves 4 to support and to locate transmission part by steel ball 5; Make the bearing difficult drop-off again that slides flexibly like this, install and maintenance cost thereby reduce.

Below the utility model is done a detailed description, but obvious, those skilled in the art can carry out various changes and improvement, and the scope of the utility model that does not deviate from appended claims and limited.
