Description

Damping fin of damping bearing

Technical Field

The utility model relates to a damping fin, concretely relates to damping fin of damping bearing.

Background

Under the working condition of the damping fin of the existing damping bearing, the temperature rise is caused by the larger friction force of the damping fin, the performance of a damping ring is influenced, the service life is shortened, the damping bearing needs to be frequently replaced, and the use cost is greatly improved. In order to overcome the above disadvantages, in the prior art, an oil groove is designed on one end surface of the damping fin for storing grease, but the damping fin of this structure has certain disadvantages: on the one hand, the damping fin surface leads to the surface to wear and tear easily because of receiving great frictional force, and on the other hand, the oil groove of damping fin easily causes the loss for it is poor to lock oily effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: the damping fin of the damping bearing can effectively lock grease, is not easy to lose, effectively delays temperature rise, and solves the problem that the service life of the existing damping fin is not long due to too large temperature rise of friction force.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a damping fin of damping bearing, is including the damping fin body that is the annular form, a terminal surface of damping fin body is the reference surface, and is equipped with the oil storage pit group that many circles arranged along its circumferencial direction on this reference surface, and every circle oil storage pit group has a plurality of oil storage pits of separately arranging, and its innovation point lies in: and a boss is arranged in the oil storage pit, and the convex surface of the boss is lower than the reference surface of the damping fin body.

In the technical scheme, the height difference between the convex surface of the boss and the reference surface of the damping fin body is 0.2 mm-0.8 mm.

In the technical scheme, the damping fin body has two circles of oil storage pit groups, the oil storage pit of the oil storage pit groups is a V-shaped pit, the vertex of each circle of V-shaped pit is on the same circumference, and the opening directions of the two circles of oil storage pit groups are opposite.

In the technical scheme, the bosses arranged in the oil storage pits are bosses corresponding to the V-shaped pits.

In the technical scheme, the height difference between the bottom surface of the oil storage pit and the convex surface of the boss in the oil storage pit is 0.2 mm-0.8 mm.

In the technical scheme, radial grooves which are uniformly distributed are arranged on the reference surface of the damping fin body.

In the above technical scheme, two ends of the radial groove on the damping fin body along the length direction are respectively provided with a guide inclined plane.

The utility model discloses the positive effect who has is: after the damping fin of the damping bearing of the utility model is adopted, because one end surface of the damping fin body of the damping fin is a datum plane, and the reference surface is provided with a plurality of circles of oil storage pit groups which are arranged along the circumferential direction of the reference surface, each circle of oil storage pit group is provided with a plurality of separately arranged oil storage pits, the oil storage pits are internally provided with bosses, and the convex surface of the boss is lower than the reference surface of the damping fin body, on one hand, the boss is arranged in the oil storage pit of the utility model, which can effectively lock grease and prevent loss, so that the grease can effectively play a role in lubricating and radiating under the working condition of the damping fin of the utility model, and prevent the damping fin from heating up due to friction so as to influence the performance of the damping fin, on the other hand, even if the reference surface of the damping fin is abraded, the boss in the oil storage pit can make up the influence of abrasion of the reference surface, and the service life is prolonged.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, but is not limited thereto.

As shown in fig. 1, 2, 3, 4, 5, a damping fin of damping bearing, including the damping fin body 1 that is the annular form, an end face of damping fin body 1 is the reference surface, and is equipped with the oil storage pit group that many circles arranged along its circumferencial direction on this reference surface, and every circle oil storage pit group has a plurality of oil storage pits 2 of separately arranging, be equipped with boss 3 in the oil storage pit 2, and boss 3's convex surface is less than the reference surface of damping fin body 1.

In order to make the utility model discloses the structure is more reasonable, is suitable for the damping fin of multiple specification, the difference in height between the convex surface of boss 3 and the reference surface of damping fin body 1 is 0.2mm ~0.8 mm. The bottom surface of oil storage pit 2 and the difference in height of the convex surface of this oil storage pit 2 boss 3 are 0.2mm ~0.8 mm.

As shown in fig. 4, the advantage of this design is that, in order to accord with the use environment, the horizontal hunting, damping fin body 1 has two circles of oil storage pit group, the oil storage pit 2 of oil storage pit group is the V font pit, the summit of every circle V font pit is on same circumference, and the opening direction of two circles of oil storage pit group V font pits is opposite.

As shown in fig. 4, in order to further improve the rationality of the present invention, the boss 3 provided in the oil storage pit 2 is a boss corresponding to the V-shaped pit. Certainly, the oil storage pit of the present invention can be designed into the shape of eight diagrams or half moon, and the boss correspondingly designed to the oil storage pit of eight diagrams or half moon is the boss of eight diagrams or half moon.

As shown in fig. 4, in order to effectively discharge the dirty bits that the damping fin produced in the use to and conveniently annotate grease, be equipped with the radial groove 4 of evenly arranging on the reference surface of damping fin body 1, the utility model discloses the damping fin design has four radial grooves.

As shown in fig. 4, in order to facilitate discharging of the dirty chips and the grease, the two ends of the radial groove 4 of the damping fin body 1 along the length direction thereof are respectively provided with a guide inclined surface.

The utility model discloses damping fin's structural advantage is: on the one hand, the utility model discloses a be equipped with the boss in the oil storage pit, can effectively pin the grease, prevent to run off for the damping fin is under operating conditions, and the grease can play lubricated radiating action, prevents the intensification that the damping fin arouses because of the friction, and then influences the damping fin performance, and on the other hand, even the reference surface of damping fin has received wearing and tearing, and boss in the oil storage pit can compensate the influence that the reference surface wearing and tearing received, has prolonged life.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
