Description
Technical Field
The utility model belongs to the technical field of tobacco machinery, concretely relates to axle sleeve formula fan wheel transmission shaft.
Background
In mechanical equipment, a transmission part is connected with a workpiece by using a transmission shaft, and a bearing needs to be periodically maintained and replaced during production. Because transmission bearing need with the bearing frame laminating, guarantee its leakproofness, set up the shaft shoulder and fix a position at another direction of bearing usually in the middle part of the transmission shaft, this just leads to dismantling driving medium and fan wheel completely and just can changing the bearing, still need install after the change is accomplished. The impeller is large in size, heavy in weight, large in disassembly difficulty, long in time consumption, large in manpower input and adverse effect on equipment maintenance.
Therefore, there is a need for a shaft sleeve type fan impeller transmission shaft to facilitate the replacement of the bearing.
Disclosure of Invention
The utility model discloses a be applicable to fan impeller transmission and utilize the axle sleeve to replace shaft shoulder location, bearing position adjustable transmission shaft, when the transmission bearing needs to be changed, need not dismantle the fan and can change, the operation convenience is high, efficient, the human cost input is low.
In order to achieve the above purpose, the utility model is realized by the following technical scheme:
the utility model provides a axle sleeve formula fan wheel transmission shaft, includes that driving medium installation shaft shoulder, bearing installation fixed shaft shoulder, axle sleeve and fan wheel installation shaft shoulder, bearing installation fixed shaft shoulder one end and driving medium installation shaft shoulder welding, the other end and fan wheel installation shaft shoulder welding, the axle sleeve passes through clearance fit mode and installs on bearing installation fixed shaft shoulder.
Furthermore, a key groove I for fixing the transmission piece is arranged on the transmission piece mounting shaft shoulder.
Further, a key groove II for fixing the fan impeller is arranged on the fan impeller mounting shaft shoulder.
Furthermore, the position of the bearing on the bearing mounting and fixing shaft shoulder can be adjusted.
Furthermore, the bearing mounting and fixing shaft shoulder is provided with threads for connecting a positioning ring, and the positioning ring is matched with the bearing mounting and fixing shaft shoulder locking bearing.
The utility model discloses beneficial effect:
the utility model discloses a shaft sleeve replaces the shaft shoulder, still can realize propeller shaft bearing's accurate location under the condition that changes the structure, moreover, when changing propeller shaft bearing, the accessible is dismantled the shaft sleeve and is realized the quick replacement and the installation of bearing, promote the operating efficiency, it is efficient to have, characteristics such as the operation is convenient, need not again to dismantle fan wheel etc. completely, manpower cost is effectively practiced thrift to original mode, in addition, the new construction of axis body has realized less spare part dismantlement, effectively avoided the damage of dismouting in-process to spare part, reduce cost of maintenance.
Description of the drawings:
FIG. 1 is a perspective view of the present invention;
fig. 2 is a front view of the present invention.
In the figure, 1-transmission part installation shaft shoulder, 2-bearing installation fixed shaft shoulder, 3-shaft sleeve, 4-fan impeller installation shaft shoulder, 5-key groove I and 6-key groove II.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the embodiments of the present invention and the accompanying drawings, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, a shaft sleeve 3 type fan impeller transmission shaft comprises a transmission member mounting shaft shoulder 1, a bearing mounting fixing shaft shoulder 2, a shaft sleeve 3 and a fan impeller mounting shaft shoulder 4, wherein one end of the bearing mounting fixing shaft shoulder 2 is welded with the transmission member mounting shaft shoulder 1, the other end is welded with the fan impeller mounting shaft shoulder 4, a key groove I5 for fixing a transmission member is arranged on the transmission member mounting shaft shoulder 1, the transmission member is mounted on the transmission member mounting shaft shoulder 1, during mounting, the transmission member is connected through a mounting key in a key groove I5, a key groove II6 for fixing a fan impeller is arranged on the fan impeller mounting shaft shoulder 4, the fan impeller is mounted on the fan impeller mounting shaft shoulder 4 and fixed through the mounting key in the key groove II6, the shaft sleeve 3 is mounted on the bearing mounting fixing shaft shoulder 2 in a clearance fit manner, and the shaft sleeve 3 is detachably mounted by clearance fit, and the installation is all very convenient with the dismantlement, during the installation, install the bearing on bearing installation fixing bearing earlier, then carry out the installation of axle sleeve 3 again, fix a position and seal the bearing outer end through axle sleeve 3, adopt axle sleeve 3 to replace the shaft shoulder, still can realize propeller shaft bearing's accurate location under the condition of change structure, furthermore, when changing propeller shaft bearing, the accessible is dismantled axle sleeve 3 and is realized the quick replacement and the installation of bearing, promote the operating efficiency, need not to dismantle fan wheel etc. completely again, manpower cost is effectively practiced thrift to original mode, furthermore, the new construction of axis body has realized less spare part dismantlement, effectively avoided the damage of dismouting in-process to spare part, reduce cost of maintenance. Meanwhile, after the transmission shaft is structurally modified, compared with the original transmission shaft, the strength of the transmission shaft is not obviously changed, the service life of parts after modification can be ensured, and the consumption of maintenance spare parts is reduced.
The bearing is in bearing installation fixed shaft shoulder 2 on the adjustable position, be provided with the screw thread that is used for connecting the position circle on the bearing installation fixed shaft shoulder 2, 2 locking bearings of position circle cooperation bearing installation fixed shaft shoulder, fix a position, seal through axle sleeve 3 and position circle to the both ends of bearing, simultaneously, because 2 threaded connection of position circle and bearing installation fixed shaft shoulder, the position is adjustable about it, and axle sleeve 3 installs at bearing installation fixed shaft shoulder 2 through clearance fit mode, the position is also adjustable about it, consequently, fix a position the bearing through position circle and axle sleeve 3, not only convenient to detach, but also can realize that the position of bearing on bearing installation fixed shaft shoulder 2 is adjustable, in order to adapt to different installation demands, can be to a certain extent compatible similar equipment.
The present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
