Description
Technical field
The utility model belongs to taper roller processing technique field, is specifically related to a kind of grinding machine for spherical fiducial surface of conical roller.
Background technology
Along with the keen competition in bearing market, user is more and more higher to the requirement of bearing quality.From the taper roll bearing fail result of user feedback, the fatigue flake of rolling element ball basal plane accounted for the more than 50% of bearing failure sum in recent years.From fail result analysis, main cause be the contact area of bearing inner sleeve large-flange end face and roller ball basal plane be less than product requirement 80% or more than, trace sth. to its source is because spherical base surface of tapered roller radius of curvature is too large, not only make the contact point of rib end face and roller ball basal plane outer, also make effective contact rate cannot reach the more than 80% of product requirement.In processing when spherical base surface of tapered roller, when in the radius of curvature of the processing roller range of work at existing grinding machine, as long as pack guide wheel dish and the separator of respective diameters into according to processed model.But be limited to the equipment installation requirement of existing grinding machine for spherical fiducial surface of conical roller, in the time of the taper roller of processing ball basal plane radius of curvature SR≤90, because needs are installed minor diameter guide wheel dish, the problem that makes workpiece cannot directly enter grinding area with regard to leading wheel diameter about there will be the mounting flange diameter of left and right guide wheel dish to be greater than, roller just can not be realized normal process and produce.Therefore, utilize existing grinding machine for spherical fiducial surface of conical roller to be difficult to process the roller ball basal plane of radius of curvature SR≤90.
Utility model content
The purpose of this utility model is the problem existing for prior art, and a kind of simple in structure and grinding machine for spherical fiducial surface of conical roller that machining accuracy is high is provided.
For this reason, the utility model adopts following technical scheme:
A kind of grinding machine for spherical fiducial surface of conical roller, comprise symmetrically arranged two guide wheel dishes, separator, emery wheel, wheel stand and emery wheel rotating shaft, described guide wheel dish is provided with guide wheel flange, described separator is provided with separator flange, emery wheel is provided with grinding wheel flange, described guide wheel flange is provided with guide wheel flange spacer shell, and the outer ring portion of described guide wheel flange spacer shell connects wheel stand; Described separator flange is provided with separator flange spacer shell.
Described grinding wheel flange is provided with grinding wheel flange spacer shell, and described grinding wheel flange spacer shell is connected with emery wheel rotating shaft.
Between described separator and guide wheel dish, be provided with trimmer.
The utility model passes through the setting of guide wheel flange spacer shell and separator flange spacer shell on the basis of existing grinding machine for spherical fiducial surface of conical roller, can be adopting time corresponding employing small size guide wheel flange and the separator flange of small size guide wheel dish and separator, the problem of leading wheel diameter about having avoided guide wheel flange diameter to be greater than and make workpiece cannot directly enter grinding area, and then can machining small curvature radius radius roller ball basal plane.
The beneficial effect that the utility model has is thus: while adopting small size guide wheel dish and separator by solution guide wheel flange diameter be greater than the problem of leading wheel diameter make SR≤90,2 ° of < α≤5 ° (α is roller semi-cone angle) large cone angle roller be processed into possibility; Simple in structure, the installation dimension that has solved guide wheel flange and separator flange by setting up guide wheel flange spacer shell and separator flange spacer shell is the irreducible problem of adaptation grinding machine installation requirement; Machining accuracy is high, owing to having set up grinding wheel flange spacer shell on grinding wheel flange, therefore can use emery wheel and the grinding wheel flange of minor diameter instead, makes the operating position of emery wheel also therefore improve more flexibly the machining accuracy of equipment.

The specific embodiment
As shown in Figure 1, a kind of grinding machine for spherical fiducial surface of conical roller, comprises symmetrically arranged guide wheel dish 1 and guide wheel dish 2, separator 3, emery wheel 4, wheel stand 5 and emery wheel rotating shaft 6.Due to guide wheel dish 1,2 symmetrical configuration, therefore the structure with guide wheel dish 1 describes, particularly, guide wheel dish 1 is provided with guide wheel flange 7, separator 3 is provided with separator flange 8, emery wheel 4 is provided with grinding wheel flange 9, and guide wheel flange 7 is provided with guide wheel flange spacer shell 10, and the outer ring portion 11 of guide wheel flange spacer shell 10 connects wheel stand 5; Separator flange 8 is provided with separator flange spacer shell 12.Grinding wheel flange 9 is provided with grinding wheel flange spacer shell 13, and grinding wheel flange spacer shell 13 connects emery wheel rotating shaft 6.For ease of adjusting the spacing of separator 3 and guide wheel dish 1, between separator 3 and guide wheel dish 1, be also provided with trimmer 14.
In the utility model, due to the setting of guide wheel flange spacer shell 10 and separator flange spacer shell 12, while adopting minor diameter guide wheel dish 1 and separator 3, can adopt minor diameter guide wheel flange 7 and separator flange 8 simultaneously, avoid guide wheel flange 7 diameters in the time of the taper roller of processing ball basal plane radius of curvature SR≤90 to be greater than guide wheel dish 1 diameter and to make workpiece cannot directly enter the problem of grinding area, simultaneously because guide wheel flange 7 can not adapt to the original installation site of wheel stand 5 after using minor diameter flange instead, at this moment guide wheel flange spacer shell 10 is installed on wheel stand 5 and can on the basis that does not change original installation site, realizes the fixing of guide wheel dish 1.
As shown in Figure 2, specifically add and man-hour workpiece to be processed 15 is flush-mounted on separator 3, guide wheel dish 1 is with guide wheel dish 2 counter-rotation and then drive workpiece 15 around self axis rotation, and separator 3 is in the time that central axis rotates, and emery wheel 4 can be implemented grinding to workpiece 15 under different operating position.Owing to being arranged with emery wheel spacer shell 13, the installation diameter of the utility model medium plain emery wheel 4 and grinding wheel flange 9 can be less than original diameter, and therefore emery wheel 4 has obtained larger working space, and ground effect and grinding accuracy are improved.
