Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a high-sealing bearing. Background Art

[0002] Sealed bearings are bearings with a seal to prevent dust, moisture and other impurities from entering the bearing, while also preventing lubricant loss. Sealed bearings can reduce maintenance costs and time and extend the service life of the bearing. They are widely used in various industrial equipment and machinery, such as automobiles, motors, pumps, fans, etc.

[0003] Most of the current sealed bearings use two seals to seal the openings on both sides of the gap between the inner and outer rings of the bearing. However, the seals of the current sealed bearings are mostly suspended inside. When subjected to external force factors such as external impact, the seals in the ring state are easily deformed, thereby affecting the sealing effect of the overall bearing. Utility Model Content

Embodiment 1

[0025] like Figure 2-5 As shown, in the present embodiment, ball grooves 107 are provided at the joints of the inner walls of the No. 1 outer ring 101 and the No. 2 outer ring 104 and at the joints of the outer walls of the No. 1 inner ring 105 and the No. 2 inner ring 106, and sealing grooves 108 are provided at the upper edge of the inner wall of the No. 1 outer ring 101, the lower edge of the inner wall of the No. 2 outer ring 104, and the upper edge of the outer wall of the No. 1 inner ring 105 and the lower edge of the outer wall of the No. 2 inner ring 106; both sides of each load ball 203 are respectively abutted against the two groups of ball grooves 107, and each abutting arc plate 304 slides against the sealing groove 108 at the corresponding position.

The retaining frame 201 and the ball retaining ring 202 are composed of two upper and lower components spliced ​​together. Load balls 203 are movably clamped in the plurality of ball retaining rings 202.

[0031] In specific implementation, during assembly, first splice the two components that constitute the retaining frame 201 and the ball retaining ring 202, clamp and limit each load ball 203 through the ball retaining ring 202, and design the inner and outer ring structures of the bearing ring 1 as a top-down assembly type to facilitate assembly. Based on the rolling body 2, the No. 1 inner ring 105, the No. 2 inner ring 106 and the No. 1 outer ring 101, the No. 1 inner ring 105 are assembled on the inner and outer sides of the retaining frame 201 respectively.
