Abstract
The invention provides an improved wheel head structure which can ensure that when a main shaft and a bearing for fixing the main shaft generate heat, the bearing deviates far from a grinding wheel, so that hot deformation of the main shaft can not influence the grinding precision and effect of the grinding wheel and the precision and quality of the grinding of the grinding wheel are improved. The improved wheel head structure comprises the main shaft of the grinding wheel, wherein the main shaft of the grinding wheel is connected with a motor through a belt pulley and a belt which are sleeved outside the main shaft of the grinding wheel; the main shaft of the grinding wheel is arranged in a shell which is arranged in a planker; on combing positions of the main shaft of the grinding wheel and the shell, the main shaft of the grinding wheel is sleeved with bearings, the bearing close to the belt pulley is a bearing for bearing, and the outer end face of the bearing on the other side is provided with a flange of the main shaft; and a wheel head is arranged in the flange of the main shaft. The improved wheel head structure is characterized in that the bearing on the other side is an angular contact ball bearing.
Description
(1) technical field
The present invention relates to material grinding fine finishining field, be specially a kind of modified grinding wheel head structure.
(2) background technology
Existing grinding wheel head structure, behind the bearing heating of main shaft and fixed main shaft, the thermal deformation meeting of main shaft causes main shaft to emery wheel one side displacement, has influence on the grinding accuracy and the effect of emery wheel.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of modified grinding wheel head structure, it can satisfy behind the bearing heating of main shaft and fixed main shaft, and the thermal deformation of main shaft can not have influence on emery wheel, has improved the grinding accuracy and the quality of emery wheel.
Its technical scheme is such: it comprises grinding wheel spindle, described grinding wheel spindle is connected motor by the belt pulley that is enclosed within its outside with belt, described grinding wheel spindle is installed on housing, described housing is installed on planker, the described grinding wheel spindle place that combines with described housing, described grinding wheel spindle is set with bearing, near belt pulley one side bearing is loading bearing, its outer face of the bearing of opposite side is pressed with the spindle flange dish, bistrique is installed on described spindle flange dish, it is characterized in that: the bearing of described opposite side is an angular contact ball bearing.
It is further characterized in that:
Described angular contact ball bearing has two; Described two angular contact ball bearings are arranged back-to-back; Separate with internal axle sleeve, outer shaft between described two angular contact ball bearings; Described grinding wheel spindle middle part is with bearing holder (housing, cover); Described bearing holder (housing, cover) one end is by two nuts and described grinding wheel spindle axial restraint; The described bearing holder (housing, cover) other end press-fit in described angular contact ball bearing one side inner ring end face; Described internal axle sleeve is placed in described grinding wheel spindle, and described outer shaft is embedded in described housing.
In the said structure of the present invention, owing to adopted angular contact ball bearing, defining angular contact bearing can only be to away from emery wheel one side displacement, so after grinding wheel spindle and angular contact bearing heating, angular contact bearing is to moving away from emery wheel one lateral deviation, thereby the thermal deformation of grinding wheel spindle can not have influence on the grinding accuracy and the effect of emery wheel, has improved the precision and the quality of wheel grinding.
