Description
Technical Field
The invention relates to the field of lunch boxes, in particular to a combined bearing structure.
Background
The Bearing (Bearing) is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision.
The bearings can be classified into rolling bearings and sliding bearings according to the frictional properties of the moving elements. Rolling bearings have been standardized and serialized, but have a larger radial size, vibration and noise, and a higher price than sliding bearings.
Rolling bearings generally consist of an outer ring, an inner ring, and rolling elements. Rolling bearings are classified into ball bearings and roller bearings according to the shape of the rolling elements.
When the existing bearing is assembled, the rolling bodies are positioned between the outer ring and the inner ring, in order to ensure complete assembly, the number of the rolling bodies cannot reach the optimal selection, if the holder is externally installed, the welded structure needs to be replaced after the bearing is damaged, the maintenance is difficult to realize, and the investment of enterprises is greatly increased.

In view of the above, the present invention provides a combined bearing structure to solve the above technical problems.
The technical scheme of the invention is realized as follows:
a combined bearing structure comprises an inner ring, an outer ring, a baffle ring and balls arranged between the inner ring and the outer ring; the inner ring and the outer ring are arranged coaxially;
the outer ring comprises an outer ring and two retaining rings arranged on two end faces of the outer ring, an annular groove is formed among the two retaining rings and the outer ring after the two retaining rings are connected with the outer ring, and the ball is arranged in the annular groove;
the number of the baffle rings is two, and the two baffle rings are detachably connected to two ends of the inner ring;
and a movable groove matched with the ball is arranged on the annular surface of the baffle ring.
Preferably, the inner diameter of the outer ring is equal to the total of the spherical diameters of the two balls and the outer diameter of the inner ring.
Preferably, the depth of the annular groove is less than the diameter of the ball.
Preferably, a plurality of segment-shaped grooves are further formed in the annular surface of the baffle ring, and the grooves and the movable grooves are located on two opposite surfaces of the baffle ring.
Preferably, the baffle ring is in threaded connection with the inner ring.
Preferably, a fixing piece is arranged on the inner ring.
Has the advantages that:
the invention is additionally provided with the baffle rings, the outer ring comprises an outer ring and two baffle rings arranged on two end faces of the outer ring, after the two baffle rings are connected with the outer ring, an annular groove is formed among the two baffle rings, and the annular groove is internally provided with the ball; the two baffle rings are detachably connected to two ends of the inner ring; the annular surface of the baffle ring is provided with a movable groove matched with the ball. Through setting up detachable fender ring, the quality of bearing is guaranteed to the number autonomous selection of rolling element to it is also very convenient when the later stage is dismantled and is maintained.
Drawings
FIG. 1 is a schematic structural diagram of a combined bearing structure according to the present invention.
Detailed Description
