Abstract
The utility model provides a grinding head of a self-aligning roller bearing outer ring raceway grinder and belongs to the field of grinder component devices. An existing grinding head of the grinder has the defects such as low grinding precision and low cooling effect in bearing grease lubrication. The grinding head provided by the utility model comprises a grinding head rack, a grinding wheel, a shaft and an early warning device, wherein the shaft is supported and arranged in a central shaft hole of the grinding head rack by virtue of multiple bearings; one end of the shaft is fixedly provided with the grinding wheel, the grinding wheel is fixedly connected with the grinding head rack, and multiple belt wheels are sleeved at the other end of the shaft; a pretensioning device is arranged between the end faces of the bearings; the lateral part of the grinding head rack is provided with through holes which penetrate through inner and outer walls; the through holes are formed in the bearings; the through holes are provided with air pipe joints which are communicated with air pipes. According to the grinding head, grease lubrication is replaced by oil fog lubrication, the oil fog lubrication is beneficial to the high-speed rotation of the bearings and can be used for achieving a cooling effect on the bearings; the pretensioning device is arranged between the bearings, thereby being beneficial to the self regulation of the bearings and improving the grinding precision of the grinding wheel.
Description
Technical field
The utility model belongs to grinding machine components device field, and is especially relevant with a kind of self aligning roller bearing outer ring raceway grinding machine bistrique.
Background technology
Bearing on existing grinder head is after long-time the use, and race way can wear and tear to some extent, and the bearing after wearing and tearing is unfavorable for and will affect the precision of wheel grinding workpiece, and the bearing that need to more renew at this moment substitutes, and has reduced the operating efficiency of grinding machine.The bistrique of grinding machine is to be lubricated by grease, and grease lubrication is unfavorable for the bearing under the High Rotation Speed state, and grease is not high to the cooling effect of bearing.
The utility model content
The purpose of this utility model is intended to overcome that the grinding accuracy that existing grinder head exists is lower, the lubricated not high defective of cooling effect that exists of bearing grease, provide that a kind of grinding accuracy is higher, the bearing cooling effect preferably self aligning roller bearing outer ring raceway model become grinder head.
For this reason, the utility model is by the following technical solutions: a kind of self aligning roller bearing outer ring raceway grinding machine bistrique, comprise bistrique frame, emery wheel and axle, axle is installed in the central shaft hole of bistrique frame by a plurality of bearings, one end of axle is fixedly installed emery wheel, emery wheel is fixedly connected with the bistrique frame, the other end is set with multi-wedge belt pulley, it is characterized in that, between described bearing face, pre-tightening apparatus is set, the sidepiece of bistrique frame arranges the through hole that connects inside and outside wall, and through hole is positioned at bearings mounted position, gas-tpe fitting is set on through hole, and gas-tpe fitting is connected with tracheae.
As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic.
Described pre-tightening apparatus comprises spring and spring base, and spring is arranged in the spring base inner chamber, and spring base is between bearing face, and the elastic force by spring makes bearing be in all the time best running state.
Described bearing is provided with 3.
Described multi-wedge belt pulley outer cover is equipped with protective cover, and protective cover can stop cooling water to be splashed to the polywedge bet surface, plays a protective role.
Use the utility model can reach following beneficial effect: the utility model changes grease lubrication into fog lubrication, and fog lubrication is conducive to the High Rotation Speed of bearing, and bearing has been played cooling effect; By pre-tightening apparatus is set between bearing, be conducive to the automatic adjustment between bearing, improved the grinding accuracy of emery wheel.
