Abstract
The utility model discloses a supporting structure of taper-roller centerless grinder chief axel relating to a grinder for providing for centerless grinder chief axes a supporting structure of which the chief axel is large-rigidity and high-accuracy. The utility model is characterized in that the chief axis in front of and behind the abrasive disk are provided with an internal taper double-entry cylinder roller bearing respectively, taper holes provided on the inner race of the bearings are in match with the taper body of the chief axes, one of the internal taper double-entry cylinder roller bearing is provided with a centripetal pushing bearing on the outside, the axis of thread on the outside of the two internal taper double-entry cylinder roller bearing are provided with a cap nut respectively, the centripetal pushing bearing is a diagonal contacting ball bearing. The utility model is applicable to taper-roller centerless grinder.
Description
Technical field:
The utility model relates to a kind of grinding machine, particularly a kind of supporting construction of centerless grinder main shaft.
Background technology:
What the support of conical roller centerless grinding machine main shaft was extensively adopted is single bearing shell formula structure that supports, because be supported on a side of emery wheel, main shaft is a cantilever structure, rigidity is relatively poor, the gap adjustment trouble of bearing shell and between centers and the reparation difficulty behind the bearing bush abrasion adopt the oil lubrication mode.
Summary of the invention:
The purpose of this utility model is the supporting construction of a kind of centerless grinder main shaft of design, and the rigidity of its main shaft is big, the synthesis precision height.The technical solution of the utility model is, a kind of supporting construction of conical roller centerless grinding machine main shaft, it is characterized in that: before and after emery wheel, respectively be provided with an inner conical double row cylindrical roller bearing on the main shaft of both sides, its bearing inner race is that the cone of a taper hole and main shaft matches, and the outside of an internal taper hole double row cylindrical roller bearing therein also is provided with a radial thrust bearing.On the thread spindle in two inner conical double row cylindrical roller bearing outsides, respectively is furnished with a nut.Described radial thrust bearing is a pair of angular contact ball bearing.The utility model is owing to be provided with an internal taper hole double row cylindrical roller bearing respectively on the main shaft of emery wheel both sides, thus the utility model to have the main shaft rigidity compared with the prior art big, synthesis precision height and adjusting play be advantage easily.
Description of drawings:
Accompanying drawing is a vertical section of the present utility model schematic diagram.
The specific embodiment:
The utility model is described in further detail in conjunction with above accompanying drawing, on the main shaft 1 of both sides, emery wheel 5 front and back, respectively be provided with an inner conical double row cylindrical roller bearing 4, its inner ring is that the diminished shaft of conical bore and main shaft 1 matches, on the thread spindle in this two diminished shafts outside, respectively be furnished with a nut 3, on the main shaft in a nut outside, a pair of angular contact ball bearing 2 be set.Can obtain higher centering precision easily and contact rigidity by adjusting nut.
Claims (3)
1, a kind of supporting construction of conical roller centerless grinding machine main shaft, it is characterized in that: before and after emery wheel, respectively be provided with an inner conical double row cylindrical roller bearing on the main shaft of both sides, its bearing inner race is that the cone of a taper hole and main shaft matches, and the outside of an internal taper hole double row cylindrical roller bearing therein also is provided with a radial thrust bearing.
2, the supporting construction of a kind of conical roller centerless grinding machine main shaft according to claim 1 is characterized in that: respectively be furnished with a nut on the thread spindle in two inner conical double row cylindrical roller bearing outsides.
