Abstract

The utility model relates to a thrust articulated bearing, comprising a shaft ring of which the spherical outside surface is convexly arc, and a seat ring of which the spherical inside surface is concavely arc and is matched with the spherical outside surface of the shaft ring, wherein the seat ring is arranged at the lower end of the shaft ring, and the diameter of the seat ring is slightly larger than that of the shaft ring; two inclined oil grooves are formed in the spherical inside surface of the seat ring; and the spherical inside surface and the spherical outside surface are subjected to hard chromium plating treatment. The thrust articulated bearing is simple in structure, and the inclined oil grooves and surface hard chromium plating treatment are adopted, so that the thrust articulated bearing has high lubricating property and rust resistance and is particularly suitable for port machinery and other severe occasions.

Description

Thrust articulated bearing

Technical field

The utility model relates to a kind of thrust articulated bearing.

Background technique

The present occasions such as harbour machinery thrust articulated bearing, applying working condition is abominable, should not often dismantle, thereby should ensure good lubricated and antirust ability; Traditional thrust articulated bearing raceway face adopts spherical smooth surface, and inside and outside raceway directly contacts, and produces easily insufficient lubrication, and since the thrust articulated bearing surface without special processing, antirust ability is poor.

The model utility content

Technical problem to be solved in the utility model provides a kind of simple in structure, thrust articulated bearing with good antirust and lubrication effect.

In order to address the above problem, the utility model provides a kind of thrust articulated bearing, comprising: blowout patche, the inner ball surface that outer spherical surface is convex is concave arc shape and the seat ring that matches with the outer spherical surface of blowout patche; Described seat ring is located at the lower end of blowout patche and slightly larger in diameter in blowout patche.

The inner ball surface of described seat ring is provided with two oblique oil grooves, so that storing lubricating grease makes bearing keep lubricated.

Described inner ball surface and outer spherical surface adopt hard chromium plating to process, and have improved greatly antirust ability.

The utility model has positive effect with respect to prior art: thrust articulated bearing of the present utility model is simple in structure, adopt oblique oil groove and plating hard chromium on surface to process, make this thrust articulated bearing have good lubricity and antirust ability, be specially adapted to the abominable occasions such as harbour machinery.

Description of drawings

For content of the present utility model is more likely to be clearly understood, below the specific embodiment and by reference to the accompanying drawings of basis, the utility model is described in further detail, wherein:

Fig. 1 is the sectional structure chart of thrust articulated bearing of the present utility model;

Fig. 2 is the sectional structure chart of the seat ring in the thrust articulated bearing of the present utility model.

Embodiment

See Fig. 1 and 2, the thrust articulated bearing that present embodiment provides comprises: outer spherical surface is the seat ring 2 that blowout patche 1, the inner ball surface of convex are concave arc shape and match with the outer spherical surface of blowout patche 1; The diameter of described seat ring 2 is greater than blowout patche 1.

The inner ball surface of described seat ring 2 is provided with two circular slanting oil grooves 3, so that storing lubricating grease makes bearing keep lubricated.

Described inner ball surface and outer spherical surface have the coating that adopts the hard chromium plating processing to form, and have improved greatly antirust ability.

Obviously, above-described embodiment only is for the utility model example clearly is described, and is not to be restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.

Claims

1. thrust articulated bearing is characterized in that comprising: blowout patche, the inner ball surface that outer spherical surface is convex is concave arc shape and the seat ring that matches with the outer spherical surface of blowout patche; Described seat ring is located at the lower end of blowout patche and slightly larger in diameter in blowout patche; The inner ball surface of described seat ring is provided with two oblique oil grooves; Described inner ball surface and outer spherical surface adopt hard chromium plating to process.
