The utility model discloses a realize like this, a bearing retainer ring limit structure, be in including spacing casing and setting the inboard bearing retainer ring that has the breach of spacing casing, bearing retainer ring breach department all is equipped with the arch, contained angle between the tangent line of arch and this breach department is 66 ~ 69.

The utility model discloses a further technical scheme is: the limiting shell is characterized in that an annular groove is formed in the inner side of the limiting shell, an open groove is formed in the upper end of the limiting shell, the bearing retainer ring is arranged in the annular groove, and a protrusion on the bearing retainer ring is located at the open groove.

The utility model discloses a further technical scheme is: the diameter of the bearing retainer ring is 81-85 mm.

The utility model discloses a further technical scheme is: the length of the protrusion is 6-7 mm.

The utility model discloses a further technical scheme is: the bearing retainer ring and the bulge are of an integrally formed structure.

The utility model discloses a further technical scheme is: the bearing retainer ring and the bulge are both made of spring steel.

The utility model has the advantages that: the utility model discloses a setting is at the inboard retaining ring who has the breach of spacing casing, and sets up the arch in this breach department to make and form the contained angle between the tangent line of arch and this breach department, the installation and the disassembling of the retaining ring of being convenient for improve work efficiency and reduce required cost.

Drawings

Fig. 1 is a schematic structural diagram of a bearing retainer ring provided in an embodiment of the present invention;

fig. 2 is a schematic structural diagram of a retainer ring limiting structure provided by the embodiment of the present invention.

The names of the components in the figure are as follows:

1-a limit shell; 2-a notch; 3-a bearing retainer ring; 4-bulge; 5-open slot.

Detailed Description

The embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 and 2, the bearing retainer ring limiting structure in this embodiment includes a limiting housing 1 and a bearing retainer ring 3 with a notch 2, the bearing retainer ring 3 is disposed inside the limiting housing 1, the notches of the bearing retainer ring 3 are all provided with protrusions 4, and an included angle between each protrusion 4 and a tangent line of the notch 2 is 66 ° to 69 °. The utility model discloses a setting is at 1 inboard retaining ring 3 that has breach 2 of spacing casing, and sets up arch 4 in this breach 2 department to make and form the contained angle between the tangent line of arch 4 and this breach 2 department, the retaining ring 3's of being convenient for installation and disassembly improves work efficiency and reduces required cost.

In this embodiment, as shown in fig. 1 and fig. 2, an annular groove is formed in the inner side of the limiting housing 1, an open groove 5 is formed in the upper end of the limiting housing 1, the retainer ring 3 is disposed in the annular groove, and the protrusion 4 on the retainer ring 3 is located at the open groove 5. That is, in this embodiment, the annular groove facilitates the installation and fixation of the retainer ring 3, preventing the retainer ring 3 from sliding; the upper end of the limiting shell 1 is provided with an open slot 5 and the bulge 4 on the bearing retainer ring 3 is positioned at the open slot 5 during installation, so that the bearing retainer ring 3 is convenient to install and disassemble.

In the embodiment, as shown in fig. 1, the diameter of the retainer ring 3 is 81-85 mm; the length of the bulge 4 is 6-7 mm; the bearing retainer ring 3 and the bulge 4 are of an integrally formed structure.

In this embodiment, as shown in fig. 1, the retainer ring 3 and the protrusion 4 are made of spring steel. That is, in this embodiment, the spring steel is 65Mn, and the retainer ring 3 and the protrusion 4 are made of spring steel, so that they have certain toughness and plasticity, and are subjected to a change in force during installation, so as to more easily enter the annular groove.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
