Description
Technical field
The utility model relates to grinding machine field, in particular to a kind of grinding wheel bearing.
Background technique
In the prior art, the spindle mounting structure of common grinding machine generally comprises frame body, spindle box, grinding wheel installation
Assembly, however, this common spindle mounting structure, during grinding wheel operation, there is the precision of grinding is low, grinding wheel peace
The problems such as service life of components in dress assembly is short.
Utility model content
Big the purpose of the utility model is to provide rigidity is held, running accuracy is high, a kind of Novel sand wheel shaft with long service life
It holds.
Purpose of the utility model is realized as follows: a kind of grinding wheel bearing, including bistrique body shell, it further include setting
Grinding wheel spindle at bistrique body shell center；The grinding wheel spindle left end is fixedly connected with grinding wheel, is provided with for two sections before and after the grinding wheel spindle
The left bearing and right bearing of pairing, the bistrique body shell left and right sides are respectively arranged with left axle bearing sleeve, right axle bearing sleeve, the left axle
It holds, right bearing is mounted in left axle bearing sleeve and right axle bearing sleeve；Left bearing lid is provided on the left of the left bearing；The right bearing
Right side is provided with right bearing lid.
Compared with prior art, the utility model has the beneficial effect that due to being provided with double pairings in main shaft front and back end
Bearing, two bearings are back-to-back to be fitted together as supporter, can be born the larger radially, axially joint based on radial load and be carried
Lotus；Due to the setting of locking nut, bearing is pre-tightened, and obtain higher support stiffness and running accuracy, in operation
Frictional force it is small, wear it is low, the service life is longer.
As a preferred embodiment of the present invention, between the left bearing and left bearing lid, right bearing and right bearing lid it
Between be provided with locking nut.
As the further preferred scheme of the utility model, oil sealing dress is provided on the right side of the left bearing, on the left of right bearing
It sets.
As the further preferred scheme of the utility model, the right facade of the left bearing lid and the left facade of left axle bearing sleeve
In the same plane；The right facade of the left facade of the right bearing lid and right axle bearing sleeve is in the same plane.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 bistrique body shell, 2 grinding wheel spindles, 3 grinding wheels, 4 left bearings, 5 right bearings, 6 left axle bearing sleeves, 7 right axle bearing sleeves, 8 is left
Bearing cap, 9 right bearing lids, 10 locking nuts, 11 oil sealings.
Specific embodiment
As shown in Figure 1, a kind of grinding wheel bearing, including bistrique body shell 1, it further include that 1 center of bistrique body shell is set
Grinding wheel spindle 2；2 left end of grinding wheel spindle is fixedly connected with grinding wheel 3, and 2 two sections of front and back of grinding wheel spindle is provided with the left bearing 4 and right bearing of pairing
5, left axle bearing sleeve 6, right axle bearing sleeve 7 are respectively arranged at left and right sides of bistrique body shell 1, and left bearing 4, right bearing 5 are mounted on left bearing
In set 6 and right axle bearing sleeve 7；Left bearing lid 8 is provided on the left of left bearing 4；The right side of right bearing 5 is provided with right bearing lid 9.
Locking nut 10 is provided between above-mentioned left bearing 4 and left bearing lid 8, between right bearing 5 and right bearing lid 9.
Oil-sealing arrangement 11 is provided on the left of above-mentioned 4 right side of left bearing, right bearing 5.
The left facade of the right facade of above-mentioned left bearing lid 8 and left axle bearing sleeve 6 is in the same plane；A left side for right bearing lid 9 is vertical
The right facade of face and right axle bearing sleeve 7 is in the same plane.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed by the utility model, this
For the technical staff in field according to disclosed technology contents, not needing creative labor can be special to some of which technology
Sign makes some replacements and deformation, these replacements and deformation are within the protection scope of the present utility model.
