Abstract

The utility model provides an outer spherical bearing provided with a cover cap, comprising a bearing outer ring, a bearing inner ring, a maintaining shelf, a rolling body and a sealing ring. The cover cap is arranged at one side of the bearing; the circumference of the opening position of the cover cap is evenly distributed with at least two jack catches; the outer surface of the bearing outer ring is provided with a groove along the circumference; the cover gap is clamped and connected in the groove on the outer surface of the bearing outer ring through jack catches; the transverse plane center of the cover gap is provided with a through hole or not; the cover gap is in cone frustum shape. Besides, the outer spherical bearing has the function of sealing, the added cover gap is provided with a sealing again for effectively preventing the outside oil liquid, the dust and the like from adhering on the sealing ring; simultaneously the added cover gap also has the function of guarding the bearing from being impacted by other objectives.

Description

The bearing with spherical outside surface of band cover cap

Technical field

The utility model relates to technical field of bearings, especially a kind of bearing with spherical outside surface with cover cap.

Background technique

Advantages such as bearing with spherical outside surface has compact structure, and is easy to loading and unloading, and the self-aligning scope is wide, thereby use extensive at various production fields.General bearing with spherical outside surface carries seal ring, be filled with an amount of grease lubricate in the bearing, but bearing with spherical outside surface in use, its side exposes outside rather than complete closed usually, the sealability of bearing just can only be guaranteed by its seal ring that carries, impurity such as extraneous fluid, dust can stick on the seal ring, infiltrate bearing inside with the wearing and tearing of seal ring, influence the greasy property of bearing, simultaneously, the side of bearing with spherical outside surface exposes outside, and is subjected to the collision of other objects during use easily, causes the damage of bearing.

The model utility content

The technical problems to be solved in the utility model is: the utility model has overcome shortcoming of the prior art, a kind of bearing with spherical outside surface with cover cap is provided, this bearing has better sealability in use, and can prevent that bearing is subjected to the collision of other objects when using.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of bearing with spherical outside surface with cover cap, has bearing outer ring, bearing inner race, retainer, rolling element, seal ring, described bearing one side is provided with cover cap, the open card of cover cap is connected on the outer surface of bearing outer ring, along the circumferential direction has on the outer surface of bearing outer ring to be used for the groove that cover cap snaps in.

Furtherly, described cap opening place circumference equal portions are provided with at least two claws, have through hole at the end face center of cover cap or cover cap end face center does not have through hole, cover cap be shaped as truncated cone.

The beneficial effects of the utility model are: after the utility model adopts above scheme; bearing with spherical outside surface is except the sealing function that itself has; the cover cap that installs additional has increased sealing together again; can prevent effectively that impurity such as extraneous fluid, dust from sticking on the seal ring; strengthened the sealing effect of bearing, the cover cap that installs additional simultaneously also can play and prevent that bearing is subjected to the protective action of other object collisions.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

1. bearing outer rings, 11. grooves, 2. bearing inner races, 3. retainers, 4. rolling elements, 5. seal rings, 6. cover caps, 61. claws among the figure

Embodiment

The bearing with spherical outside surface of band cover cap as shown in Figure 1, has bearing outer ring 1, bearing inner race 2, retainer 3, rolling element 4, seal ring 5, be provided with a cover cap 6 in bearing one side, cover cap 6 opening upper and lower settings have two claws 61, and cover cap 6 is connected to by claw 61 on the outer surface of bearing outer ring 1, along the circumferential direction have on the outer surface of bearing outer ring 1 to be used for the groove 11 that cover cap 6 claws 61 snap in, the end face center of cover cap 6 does not have through hole, be blind lid form, when the end face center of cover cap 6 has through hole, then be the logical form of covering, cover cap 6 be shaped as truncated cone, it also can be terrace with edge shape, shapes such as semicircle sphere during use, only need be connected to the claw 61 of cover cap 6 groove 11 interior the getting final product on the bearing outer ring 1.The bearing with spherical outside surface of this band cover cap 6 can improve the sealing effect of bearing greatly, prevents that bearing is subjected to other object collisions and causes damage.
