Abstract

The utility model relates to an easily-lubricated isolating block in the field of bearings. The isolating block comprises an isolating-block body, wherein both ends of the isolating-block body are respectively provided with a concave cambered surface; the bottom center of the concave cambered surface is provided with a groove, and the middle position of the concave cambered surface is provided with a circular-ring slot which is concentric with the groove; a plurality of oil slots symmetrically extend out of the groove towards the edge of the concave cambered surface, and the oil slots are respectively and crosswise communicated with the circular-ring slot; and the surface of a ball contacted with the concave cambered surface of the isolating block is effectively lubricated through the isolating block in the working process of a bearing, and therefore the phenomena that the operation of the bearing is influenced and the service life is shortened due to the over-dried ball rolling of the bearing are avoided.

Description

A kind of easily lubricated spacing block

[technical field]

The utility model relates to field of bearings, especially relates to a kind of easily lubricated spacing block that ball in the bearing is lubricated be convenient to.

[background technique]

Known, common retainer has two kinds in bearing, and a kind of is the segmented retainer, the spacing block retainer that another kind is made up of a plurality of spacing blocks; In conjunction with the accompanying drawings 1, what select for use substantially in the spacing block retainer at present is the spacing block of solid cylinder body structure, its two ends are equipped with the concave arc surface on corresponding ball surface, advance so that make ball promote spacing block in rolling process, i.e. spacing block and ball same moved further on raceway; Because bearing is in operation process, its commutation and impulsive load are to producing bigger influence the working life of ball, fray for fear of ball, guarantee the starting torque and the running accuracy of bearing, improve the whole service life of bearing, sufficient lubricating just must be arranged between spacing block and the ball, but because the reasons in structure of existing spacing block, the lubricant grease on ball surface is easily scraped stripping by the concave arc surface edge of spacing block in the rolling process of ball, thereby it is lubricated fully to make the ball surface that contacts with the spacing block concave arc surface be difficult to obtain, therefore very easily cause bearing under the state of lack of lubrication, to run up, make the surface of ball produce rigid friction at the long-time concave arc surface that rolls back and spacing block, thereby make spacing block that the damage phenomenon take place because of frictional force is excessive, and then cause bearing effectively to turn round, promptly reduced the running life of bearing.

[summary of the invention]

In order to overcome the deficiency in the background technique, the utility model discloses a kind of easily lubricated spacing block, described spacing block can make the ball surface that contacts with the spacing block concave arc surface obtain effective lubricating in the bearing working process, thereby has avoided bearing to cross the phenomenon generation that the drought rolling influences the reduction of bearing operation life-span because of ball.

To achieve these goals, the utility model adopts following technological scheme:

A kind of easily lubricated spacing block, described spacing block comprises the spacing block body that two ends are equipped with concave arc surface; The bottom centre of described concave arc surface is provided with groove, and is provided with an annular groove concentric with groove at the medium position of concave arc surface; Described groove extends many oil grooves to concave arc surface edge symmetry, and oil groove intersects perforation with annular groove respectively.

Described easily lubricated spacing block, the described groove that is positioned at spacing block body two ends connects the formation through hole mutually.

Described easily lubricated spacing block, the described oil groove correspondence that is positioned at spacing block body two ends is staggered.

Described easily lubricated spacing block, described oil groove is provided with 4～8 at least.

Owing to adopt aforesaid technological scheme, the utlity model has following beneficial effect:

Described easily lubricated spacing block, by effectively reduced the area of contact between ball and the spacing block at the groove that is provided with on the concave arc surface of spacing block body, annular groove and oil groove, the corresponding frictional force that reduced, and the hole of the groove by each groove concave arc surface that remedied spacing block can't store the defective of grease, thereby utilized the lubricant grease in the groove fully effectively the ball surface that contacts with the spacing block concave arc surface to be lubricated, avoided spending the running life that the drought rolling reduces bearing because of ball.

[embodiment]

Can explain the utility model in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope, and the utility model is not limited to the following examples;

2～3 described easily lubricated spacing blocks in conjunction with the accompanying drawings, described spacing block comprises the spacing block body 1 that two ends are equipped with concave arc surface 2; Concave arc surface 2 bottom centre of described spacing block body 1 each end are equipped with groove 3, and be equipped with an annular groove 4 concentric with groove 3 at the medium position of each end concave arc surface 2, promptly annular groove 4 is with groove 3 edges of end face and the medium position between concave arc surface 2 edges; Described groove 3 extends many oil grooves 5 to the concave arc surface 2 edge symmetries with end face, described oil groove 5 is provided with 4～8 at least, be preferably and be provided with 4, and oil groove 5 intersects perforation respectively with the annular groove 4 of end face is corresponding, thereby utilize at groove 3, the lubricant grease that stockpiles in annular groove 4 and the oil groove 5 effectively is lubricated the ball surface that contacts with concave arc surface 2, promptly when bearing operation, the lubricant grease on ball surface can flow into corresponding oil groove 5 by the oil groove 5 outer end notches that are located at concave arc surface 2 edges, in annular groove 4 and the groove 3, and corresponding ball surface is lubricated, thereby the edge that has effectively reduced spacing block body 1 concave arc surface 2 is scraped the phenomenon of stripping ball surface lubrication grease and is taken place, and makes the ball in the bearing have better lubricating condition.

4 described easily lubricated spacing blocks in conjunction with the accompanying drawings, the groove that is positioned at spacing block body 1 two ends concave arc surface 2 bottom centre connects mutually and forms through hole 6, thereby makes described spacing block provide lubricated to two balls that are in contact with it simultaneously by lubricant grease moving in through hole 6; In order to strengthen the effective intensity of described spacing block, oil groove 5 correspondences that are positioned at spacing block body 1 two ends can be staggered.

When implementing easily lubricated spacing block described in the utility model, only need described spacing block is assembled in the corresponding ball bearing, and make in described groove, annular groove and the oil groove and be filled with lubricant grease, promptly can when this ball bearing running, carry out lubricated fully to the ball surface that contacts with spacing block body concave arc surface.

Carefully not stating in the above content is prior art partly, does not state so run business into particular one.
