Abstract
Disclosed is a method for machining a crown of an outer ring raceway of a tapered roller bearing through a non-numerical-control internal grinder. According to the method, an electric spindle is slightly uplifted by adjusting a spindle adjusting bolt installed on a base of a grinding wheel; when a diamond pen of a trimmer operates from the point A at one end of the grinding wheel to the point B of the other end of the grinding wheel, as a small spatial included angle theta exists between the trimming track AB and the center line of the grinding wheel, the outline of the grinding wheel is trimmed into a smooth hyperbolic curve; then a horizontal adjusting bolt is adjusted to enable the hyperbolic curve to be symmetrical, and then the trimmed outline of the grinding wheel is in a smooth and symmetrical hyperbolic curve type. The position relation between the trimming track AB and the center line of the grinding wheel is changed, namely the small spatial included angle theta is made to exist between the trimming track AB and the center line of the grinding wheel, and accordingly the internal grinder without the crown machining capacity has the capacity of machining the crown.
Description
technical field:
The present invention relates to Production of bearing technical field, be specifically related to a kind of method of processing taper roll bearing outer ring raceway convexity on non-numeral-controlled internal grinder.
Background technology
The convexity of taper roll bearing is a key factor that affects bearing fatigue life.Along with the appearance of numerical control convexity grinding machine, oneself is comprehensively universal in industry for convexity process technology, however non-numerically control grinder owing to self there is no the working ability of convexity, this has brought a difficult problem to processing of convexity, is also the difficulty that industry faces.Non-numeral-controlled internal grinder is when crushing, and due to dressing track AB and the parallel (see figure 1) of emery wheel center line, after crushing, its profile is a straight line, therefore cannot carry out outer ring raceway Crowning Grinding.Moreover because the impact of machine tool accuracy can make the outer ring raceway face after processing not protruding anti-recessed, this situation is certainly unallowed in the processing of bearing ring.
Summary of the invention
A kind of method that the invention provides non-numerically control grinder processing taper roll bearing outer ring raceway convexity, has thoroughly solved the problem that there is no the internal grinder of convexity working ability processing taper roll bearing outer ring raceway convexity.
for this reason, adopt following technical scheme:a kind of method of non-numeral-controlled internal grinder processing taper roll bearing outer ring raceway convexity, by conciliation, being arranged on tune axle bolt on emery wheel base lifts the electric main shaft trace that makes progress, when the diamond pen of trimmer runs to emery wheel other end B point from one end A point of emery wheel, because dressing track AB and emery wheel center line exist a micro-space angle θ, emery wheel profile is just accomplished a level and smooth hyperbola like this; Then adjusting horizontal adjusting bolt and make described hyperbola symmetrical, is level and smooth, symmetrical hyperbolic-type thereby make the emery wheel profile after finishing.
the present inventionby changing the position relationship of dressing track AB and emery wheel center line, namely allow and between dressing track line AB and emery wheel center line, produce a micro-space angle θ.Thereby make not have the internal grinder of convexity working ability to possess the ability of processing convexity.
Accompanying drawing explanation
Fig. 1 is the structural analysis schematic diagram that existing non-numeral-controlled internal grinder can not be processed convexity;
Fig. 2 is the structural analysis schematic diagram that non-numeral-controlled internal grinder of the present invention can be processed convexity.
The specific embodiment
With reference to Fig. 2, a kind of method of non-numeral-controlled internal grinder processing taper roll bearing outer ring raceway convexity, by by conciliation, be arranged on tune axle bolt 7 on emery wheel base 6 make electric main shaft 2 upwards trace lift, when the diamond pen 4 of trimmer runs to emery wheel other end B point from one end A point of emery wheel 3, because dressing track AB and emery wheel center line exist a micro-space angle θ, be between 0～15 °, be specially 1 °, 2 °, 3 °, 4 °, 5 °, 6 °, 7 °, 8 °, 9 °, 10 °, 11 °, 12 °, 13 °, 14 °, 15 °.Emery wheel profile is just accomplished a level and smooth hyperbola like this; Then adjusting horizontal adjusting bolt 1 and make described hyperbola symmetrical, is level and smooth, symmetrical hyperbolic-type thereby make the emery wheel profile after finishing.With the emery wheel of this line style and adopt the grinding method of small oscillation just can obtain more satisfactory protuberance shape.
This convexity processing method has been carried out extensive use on the non-numeral-controlled internal grinders such as MZ208,3MZ2010A of our company, and the outer ring raceway convex value of processing and convexity type shape are all more stable reliable, have obtained desirable effect.
Claims (1)
1. the method for a non-numeral-controlled internal grinder processing taper roll bearing outer ring raceway convexity, it is characterized in that: by conciliation be arranged on tune axle bolt (7) on emery wheel base (6) make electric main shaft (2) upwards trace lift, when the diamond pen (4) of trimmer runs to emery wheel other end B point from one end A point of emery wheel (3), because dressing track AB and emery wheel center line exist a micro-space angle θ, emery wheel profile is just accomplished a level and smooth hyperbola like this; Then adjusting horizontal adjusting bolt (1) and make described hyperbola symmetrical, is level and smooth, symmetrical hyperbolic-type thereby make the emery wheel profile after finishing.
