Abstract
The utility model discloses a shaft connection structure capable of preventing axial movement of a sand mill main shaft. The shaft connection structure capable of preventing the axial movement of the sand mill main shaft comprises a stepped main shaft arranged inside a pedestal. The pedestal is provided with a shaft hole used for installation of the main shaft. A bearing with one end abutted against the side face of a ladder on the main shaft is arranged between the inner portion of the shaft hole and the main shaft. A belt pulley is arranged on the other side of the main shaft on the bearing. A shaft sleeve is arranged between the bearing and the belt pulley, wherein two ends of the bearing are respectively abutted tightly against the bearing and the belt pulley. The shaft connection structure is provided with the shaft sleeve arranged between the bearing and the belt pulley installed fixedly, the shaft sleeve is abutted against the bearing and the belt pulley, and then the shaft sleeve can bear friction which is transmitted to the main shaft by both the belt pulley and the bearing, and thereby the axial movement of the main shaft during operation is effectively prevented. The shaft connection structure capable of preventing the axial movement of the sand mill main shaft can be used in the filed of reform of traditional industries through advanced technologies.
Description
Technical field
The utility model relates to a kind of mechanical connecting structure, particularly relates to a kind of motive spindle syndeton.
Background technology
Along with the extensive use of China recent years to industrial coating, each manufacturing enterprise is also increasing greatly to the demand of sand mill.
If comparatively expensive to selecting with import machine price general charged of sand mill, so part domestic enterprise begins this type of sand mill research and production domesticization, but key technology details not research is thorough, and the manufacturing machine that starts hastily again causes machine to go wrong frequently after on-the-spot operation a period of time.
The outstanding shortcoming that this type of machinery exists is, and does not axially effectively lock at the main shaft of sand mill, but relies on bearing to come holding capacity fully, so in the use procedure of this type of sand mill, the situation of main shaft axial float occurs very easily.
The utility model content
For addressing the above problem, the utility model provides a kind of Axile connection structure that can effectively prevent the main shaft axial float.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of Axile connection structure that can prevent sand mill main shaft axial float, comprise the stepped main shaft that is installed in the pedestal, pedestal is provided with for the axis hole that main shaft is installed, be provided with the bearing that a side leans ladder side on main shaft between axis hole inside and main shaft, opposite side at bearing on the main shaft is installed with belt pulley, is provided with the axle sleeve that two ends hold out against with bearing and belt pulley respectively between bearing and belt pulley.
Be further used as the improvement of technical solutions of the utility model, the inboard of axle sleeve is provided with groove, and O shape circle is installed in the groove.
Be further used as the improvement of technical solutions of the utility model, the outside of bearing also is provided with bearing (ball) cover.
Be further used as the improvement of technical solutions of the utility model, bearing (ball) cover is set on the outer ring of axle sleeve.
Be further used as the improvement of technical solutions of the utility model, bearing (ball) cover is provided with the oil sealing mounting groove, is provided with oil sealing in the oil sealing mounting groove.
The beneficial effects of the utility model: this Axile connection structure is provided with the axle sleeve that leans respectively between bearing and hard-wired belt pulley at main shaft, the axle sleeve of this interpolation can bear respectively belt pulley in the spindle operation process and bearing is passed to the axial friction of main shaft, thereby has effectively prevented the axial float of main shaft in operation process.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model embodiment overall structure schematic diagram;
Fig. 2 is that the utility model embodiment uses view.
The specific embodiment
With reference to Fig. 1～2, the utility model is a kind of Axile connection structure that can prevent sand mill main shaft axial float, comprise the stepped main shaft 2 that is installed in the pedestal 1, pedestal 1 is provided with for the axis hole that main shaft 2 is installed, axis hole inside and 2 on main shaft are provided with the bearing 3 that a side leans ladder side on main shaft 2, opposite side at bearing 3 on the main shaft 2 is installed with belt pulley 4, and 4 of bearing 3 and belt pulleys are provided with the axle sleeve 5 that two ends hold out against with bearing 3 and belt pulley 4 respectively.
This Axile connection structure is provided with the axle sleeve 5 that leans respectively between bearing 3 and hard-wired belt pulley 4 at main shaft 2, the axle sleeve 5 of this interpolation can bear respectively the axial friction that belt pulley 4 and bearing 3 are passed to main shaft 2 in main shaft 2 operation process, thereby effectively prevented the axial float of main shaft 2 in operation process, can be when ensureing the sand mill safe handling, but the service life of Effective Raise sand mill integral body.
As the utility model preferred embodiment, the inboard of axle sleeve 5 is provided with groove, and O shape circle 51 is installed in the groove.
As the utility model preferred embodiment, the outside of bearing 3 also is provided with bearing (ball) cover 6.
As the utility model preferred embodiment, bearing (ball) cover 6 is set on the outer ring of axle sleeve 5.
As the utility model preferred embodiment, bearing (ball) cover 6 is provided with the oil sealing mounting groove, is provided with oil sealing 61 in the oil sealing mounting groove.
Bearing (ball) cover 6 is provided with a plurality of bolt mounting holes on its end cap plane, be close on the plane of pedestal 1 with bearing (ball) cover 6 simultaneously and also be provided with a plurality of bolts hole that cooperate with it, fastening bolt is passed bolt mounting holes on the bearing (ball) cover 6 screw in the bolt hole in the pedestal 1, can realize being fastenedly connected between bearing (ball) cover 6 and the pedestal 1.
But being tightly connected of 2 on O shape circle 51 effective guarantee axle sleeves 5 and main shaft.
The present invention has improved the axial holding capacity situation of main shaft 2, like this by adding axle sleeve 6 simple process, namely fundamentally dealt with the basic reason that main shaft 2 axial floats occur, guarantee simultaneously the stable operation of bearing 3 grades, also solved the harmful effect that bearing 3 slides and produces at main shaft 2.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
