Abstract
The invention discloses an adapter sleeve. The adapter sleeve comprises an adapter sleeve body, a taper is arranged at one end of the adapter sleeve body, a thread is connected with a small-diameter end of the taper, a tool withdrawal groove shaped in an arc is arranged at the small-diameter end of the taper, the radius of the tool withdrawal groove is 5mm, and the radiuses of the taper is 1:12. Since the tool withdrawal groove is arranged at the small-diameter end of the taper, a locking nut can be guaranteed to be continuously screwed towards a large-diameter end of the adapter sleeve, so that a better fastening effect is reached, axial float of a transmission shaft is avoided, equipment maintenance times are reduced, and maintenance expense and cost are lowered.
Description
Technical field
The present invention relates to a kind of adapter sleeve, particularly a kind of adapter sleeve for tube mill, belong to the mechanical parts technical field.
Background technique
The transmission shaft of tube mill is provided with 4 bearings, locates with 4 adapter sleeves.According to the positioning principle of adapter sleeve, during locking nut screwing, locking nut extruding bearing, thereby make relative displacement occurs between bearing and adapter sleeve, displacement is larger, and the effect of tightening is better, so this assembling form position of rigid bearing effectively theoretically.But when locking nut is screwed to, little the correcting with adapter sleeve conical surface small end of bearing bore diameter alignd, and this moment, locking nut can not continue to be screwed into, and bearing again can not be to the large end motion of adapter sleeve, so axial float so just occured in fastening bearing more fully just.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of adapter sleeve that can effectively prevent transmission shaft generation axial float.
Technical solution of the present invention is achieved in that a kind of adapter sleeve, comprises the adapter sleeve body; One end of described adapter sleeve body is provided with tapering, and the other end is provided with screw thread; Described screw thread is connected with the miner diameter end of tapering; The miner diameter end of described tapering is provided with tool withdrawal groove.
Preferably, described tool withdrawal groove is arc.
Preferably, the radius of described arc tool withdrawal groove is 5mm.
Preferably, described tapering is 1:12.。
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Adapter sleeve of the present invention because the miner diameter end of tapering is provided with tool withdrawal groove, guarantees that locking nut can continue to be screwed into toward bigger diameter end of the present invention, thereby reach better fastening effect, prevent transmission shaft generation axial float, reduced the device maintenance number of times, reduced maintenance expenses and cost.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing l is the stereogram of adapter sleeve of the present invention;
Accompanying drawing 2 is the use phase diagram of adapter sleeve of the present invention;
Wherein: 1, adapter sleeve body; 2, tapering; 3, screw thread; 4, tool withdrawal groove; 5, transmission shaft; 6, bearing; 7, locking nut.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Of the present invention a kind of adapter sleeve as shown in Figure 1 comprises adapter sleeve body 1; One end of described adapter sleeve body 1 is provided with tapering 2, and the other end is provided with screw thread 3; Described screw thread 3 is connected with the miner diameter end of tapering 2; The miner diameter end of described tapering 2 is provided with tool withdrawal groove 4; Described tool withdrawal groove 4 is arc; The radius of described arc tool withdrawal groove 4 is 5mm; Described tapering 2 is 1:12.
As shown in Figure 2, during assembling, at first adapter sleeve body 1 is enclosed within on transmission shaft 5, then bearing 6 is enclosed within on adapter sleeve body 1, the miner diameter end of the tapering 2 on its end and adapter sleeve body 1 aligns, and at last locking nut 7 is screwed into from screw thread 3 ends.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Adapter sleeve of the present invention because the miner diameter end of tapering is provided with tool withdrawal groove, guarantees that locking nut can continue to be screwed into toward bigger diameter end of the present invention, thereby reach better fastening effect, prevent transmission shaft generation axial float, reduced the device maintenance number of times, reduced maintenance expenses and cost.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
