Each concave arc surface is provided with a plurality of extension grooves evenly at intervals by employing a bottom center as a circle center, and a plurality of grooves are evenly arranged between the outer edge of each extension groove and the edge of the corresponding concave arc surface. By the aid of the isolation block, ball surfaces contacting with the concave arc surfaces of the isolation block can be effectively lubricated during operation of a bearing, so that shortening of the service life of the bearing caused by over-dry rolling of balls of the bearing is avoided.

Description

A kind of ball bearing spacing block

[technical field]

The utility model relates to field of bearings, especially relates to a kind of ball bearing spacing block that is used for isolating the ball bearing ball.

[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, and the two ends of spacing block 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 make the ball surface that contacts with the spacing block concave arc surface can not obtain sufficient lubrication, 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, promptly reduced the running life of bearing because of the drought rolling of crossing of ball causes bearing effectively to turn round.

[summary of the invention]

In order to overcome the deficiency in the background technique, the utility model discloses a kind of ball bearing 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 ball bearing spacing block, described spacing block comprise the spacing block body that two ends are equipped with concave arc surface; To be that the center of circle is even at interval with the bottom centre be provided with a plurality of extending grooves to described concave arc surface, and be provided with a plurality of grooves uniformly between the outer rim of extending groove and concave arc surface edge.

Described ball bearing spacing block, described a plurality of extending grooves are for being symmetrical arranged, and the notch face constitutes the flower shape.

Described ball bearing spacing block, described a plurality of extending grooves and a plurality of groove are staggered and arrange.

Described ball bearing spacing block, described extending groove are arranged with 6～8 at least.

Described ball bearing spacing block, the groove outer rim top of described a plurality of grooves all has the openings that connects to spacing block body outer wall.

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

Described ball bearing spacing block, by effectively reduced the area of contact between ball and the spacing block at a plurality of extending grooves that are provided with on the concave arc surface of spacing block body and a plurality of groove, utilize the groove of each groove to cheat the defective that the concave arc surface that has remedied spacing block can't store grease simultaneously, thereby be able to fully effectively the ball surface that contacts with the spacing block concave arc surface is lubricated, avoided spending the running life that the drought rolling reduces bearing because of ball by the lubricant grease in the groove; In addition, described spacing block has not only effectively reduced frictional force by reducing the area of contact between ball and the spacing block, the corresponding running life that prolongs bearing, but also reduced the raw-material use amount of spacing block, saved cost of production accordingly.
