Description
Technical Field
The utility model belongs to the field of tapered roller processing application, and particularly relates to a super-finishing roller for grinding and repairing a convexity edge of a tapered roller.
Background
The tapered roller bearing belongs to a separated bearing, and the inner ring and the outer ring of the bearing are both provided with tapered raceways. The bearing is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers. The single-row tapered roller bearing can bear radial load and single-direction axial load. When the bearing is subjected to a radial load, an axial component will be generated, so that another bearing capable of bearing an opposite axial force is required for balancing. The tapered roller is a power part for realizing rotation of the tapered roller bearing, and for this reason, the rotation efficiency of the tapered roller bearing depends on the quality of the tapered roller.
In the processing of tapered roller, the super precision of tapered roller convexity, edge modification are the key links that improve the accurate roller machining precision of circle, and the super precision grinding machine of oilstone is the key equipment of this manufacturing procedure, and in traditional course of working, all normally coping according to the angle when carrying out the grinding to super smart roller smooth roll, need to polish the use to the roller when carrying out product processing after the coping is accomplished, some surface quality problems such as oilstone scab, external diameter white seal, external diameter white line easily appear, lead to product quality to be restricted.
SUMMERY OF THE UTILITY MODEL
Aiming at the technical problems of super-precision and edge modification of the convexity of the tapered roller, the utility model provides the super-finishing roller for grinding and modifying the convexity edge of the tapered roller, which has the advantages of reasonable design, simple structure and convenient processing and can effectively avoid the surface quality problems of pimple scars of the oilstone, white marks of the outer diameter, white lines of the outer diameter and the like.
In order to achieve the purpose, the utility model adopts the technical scheme that the utility model provides an ultra-precision finishing roller for grinding and repairing the convexity edge of a tapered roller, which comprises an ultra-precision finishing roller body and rotating shafts arranged at two ends of the ultra-precision finishing roller body, wherein a chip groove is arranged on the ultra-precision finishing roller body, and the width of the chip groove is smaller than the diameter of the tapered roller.
Preferably, the chip groove is annularly arranged, and the chip groove is arranged on the superfinishing roller body at intervals.
Preferably, the chip grooves are spirally arranged on the superfinishing roller body.
Preferably, the chip grooves extend from the feeding direction of the conical rollers to the position of the penultimate oilstone.
Compared with the prior art, the utility model has the advantages and positive effects that,
1. the utility model provides a super-finishing roller for grinding and repairing the convexity edge of a tapered roller, which is characterized in that the structure of the existing super-finishing roller is improved, and the arrangement of a chip groove is utilized, so that particles generated by oilstone are quickly thrown out, thereby avoiding the influence on the tapered roller, further ensuring the appearance quality of the tapered roller and improving the market competitiveness.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings needed to be used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without inventive labor.
Fig. 1 is a schematic structural view of a superfinishing roller for tapered roller crown edge grinding provided in example 1;
in the above figures, 1, a superfinishing roller body; 11. a chip groove; 2. a rotating shaft.
Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments of the present disclosure.
The problem of considering tapered roller appearance quality mainly is that the granule that produces when the whetstone is polished again drops the problem that leads to on super smart optical axis, and for this reason, the effectual granule that drops of getting rid of the whetstone is the key of solving the problem, and for this reason, in this embodiment, set up chip groove 11 on super smart smooth roll body 1, chip groove 11's setting is mainly made things convenient for the granule that the whetstone dropped to enter into in chip groove 11, clears away through chip groove 11 again, and like this, just can not be at super smart smooth roll body 1's surface to can not cause the influence to tapered roller yet.
Also, because super smart smooth roll body 1 is in the rotating condition, like this, the granule that the centrifugal force of production will fall into in the chip groove 11 throws away to arrange the granule clean, because the granule is less and centrifugal force is not strong, for this reason, the super smart machine of oilstone can not add the protection casing.
Considering that in the oilstone superfinishing machine, the superfinishing roller functions to effect rotation of the tapered roller, which moves backwards during rotation, the width of the chip groove 11 is smaller than the diameter setting of the tapered roller in order to avoid the tapered roller moving into the chip groove 11. Thus, the arrangement of the chip grooves 11 does not affect the normal movement of the tapered rollers.
Considering that the existing oilstone super-finishing grinder is generally provided with at least 6 oilstones, for this reason, the chip discharge grooves 11 are annularly arranged, and the chip discharge grooves 11 are arranged on the super-finishing roller body 1 at intervals. The interval that this embodiment indicates is a set of unit, and each oilstone below has all set up a set of chip groove 11, and every group chip groove 11 set up 2 ~ 3 can, such setting can reduce the processingamount.
In order to further reduce the amount of machining, in the present embodiment, the chip grooves 11 are provided in a spiral shape on the superfinishing roller body 1. In this way, the helical arrangement enables full coverage of any drop in the course of rotation, and the amount of machining is preferably much smaller than the amount of machining of the flutes 11 arranged at intervals.
Considering the arrangement of the chip removal groove 11, a certain trace is also brought to the tapered roller during the grinding process of the oilstone, and for this reason, the chip removal groove 11 extends from the feeding direction of the tapered roller to the position of the last but one oilstone. Therefore, the positions of the two oilstones are reserved without the chip grooves 11, the marks can be eliminated, the probability of generating white marks by the two oilstones is lower than that of generating all the oilstones, and therefore, the quality of the product is effectively improved through the arrangement.
The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
