Abstract
The utility model discloses a bearing locking structure. The bearing locking structure comprises a bearing (1) and a stop snap ring (4), wherein a step surface (2) is formed on the external wall of the outer circle of the bearing (1); a pressure plate (5) is sleeved on the step surface (2); the pressure plate (5) is matched with the step surface (2) of the outer circle of the bearing (1) through the stop snap ring (4); and the stop snap ring (4) is positioned in a locking annular groove (3) formed on the step surface. According to the utility model, axial force when the bearing is locked is born by adding the pressure plate to the outer circle of the bearing, so that the locking reliability of the bearing is greatly improved; and the utility model has the characteristics that the bearing locking structure is ingenious in design, simple in structure, easy to assemble, low in cost and the like.
Description
Technical field
The utility model relates to a kind of bearing, particularly the keying structure on the bearing.
Background technique
Bearing is the important spare part in the mechanical transmission.When bearing was used in high temperature, airtight, the complex environment, the reliability of bearing was just particularly important.The keying structure of traditional bearing all is an installing stop snap ring in the locking groove of bearing outer ring, leans on the stop snap ring to accomplish the locking of bearing.But the ring wall of stop snap ring is generally thinner, and when axial force was big, the stop snap ring ruptured at locking groove bottom land place easily, and reliability is relatively poor, and has increased maintenance cost.
The model utility content
The utility model technical problem to be solved is to provide a kind of bearing keying structure of good reliability.
The technological scheme of the utility model is following: a kind of bearing keying structure; Comprise bearing (1) and stop snap ring (4); Its key is: on the outer wall of said bearing (1) outer ring, be provided with a step surface (2); Be set with pressing plate (5) on this step surface (2), said pressing plate (5) matches through the step surface (2) of stop snap ring (4) with bearing (1) outer ring, and this stop snap ring (4) is positioned at the annular groove of offering on the said step surface (3).
Adopt above technological scheme, on bearing, mainly born by pressing plate by the axial force that produces during the bearing locking like this through the stop loop mapping for pressing plate, and the wall thickness of this pressing plate is bigger, and structural strength is good, thereby makes the reliability of bearing locking improve greatly.
For simplified structure, convenient for assembly; It is more firm that pressing plate is installed; On the outer wall of said stop snap ring (4), be provided with the convex closure (6) of three circular arcs, these three convex closures (6) evenly distribute by circumference, and each convex closure (6) embeds in the upward corresponding pit (7) of pressing plate (5).
Said pressing plate (5) is a triangle, and moulding is simple like this, processing and fabricating is easy, cost is low.
Beneficial effect: the axial force when the utility model is born locking through on the outer ring of bearing, setting up pressing plate, improved the reliability of bearing locking greatly, have characteristics such as design is ingenious, simple in structure, assembling is easy, with low cost.

Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the structural representation of stop snap ring.
Fig. 4 is the B place partial enlarged drawing of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is made up of bearing 1, stop snap ring 4 and pressing plate 5.On the outer wall of bearing 1 outer ring, be formed with a step surface 2, the diameter of this step surface 2 is less than the external diameter of bearing 1 outer ring, and step surface 2 is positioned at the end position of bearing 1 outer ring.On said step surface 2, offer an annular groove 3, in this annular groove 3 stop snap ring 4 is housed.Said stop snap ring 4 is circle structures that do not seal, and on the outer wall of stop snap ring 4, is provided with the convex closure 6 of three circular arcs, and this three convex closures 6 evenly distribute by circumference.
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, pressing plate 5 is a triangle, and this pressing plate 5 is sleeved on the step surface 2 of bearing 1 outer ring.Inwall at pressing plate 5 has three by the equally distributed pit 7 of circumference, and this pit 7 is corresponding one by one with convex closure 6 on the stop snap ring 4, and said convex closure 6 embeds in the corresponding pit 7.Under the cooperation of the effect of stop snap ring 4 and convex closure 6 and pit 7, pressing plate 5 is positioned on the bearing 1 reliably.
Claims (3)
1. bearing keying structure; Comprise bearing (1) and stop snap ring (4); It is characterized in that: on the outer wall of said bearing (1) outer ring, be provided with a step surface (2); Be set with pressing plate (5) on this step surface (2), said pressing plate (5) matches through the step surface (2) of stop snap ring (4) with bearing (1) outer ring, and this stop snap ring (4) is positioned at the annular groove of offering on the said step surface (3).
2. bearing keying structure according to claim 1; It is characterized in that: the convex closure (6) that on the outer wall of said stop snap ring (4), is provided with three circular arcs; These three convex closures (6) evenly distribute by circumference, and each convex closure (6) embeds in the upward corresponding pit (7) of pressing plate (5).
3. bearing keying structure according to claim 1 and 2 is characterized in that: said pressing plate (5) is a triangle.
