Abstract
The utility model relates to an adapter sleeve, which comprises an adapter sleeve body. Taper is arranged at one end of the adapter sleeve body; the other end of the adapter sleeve body is provided with threads; the threads are connected with the minor-diameter end of the taper; the minor-diameter end of the taper is provided with a tool withdrawal groove; the tool withdrawal groove is in an arc shape; the radius of the arc-shaped tool withdrawal groove is 5mm; and the taper is 1:12. According to the adapter sleeve, as the minor-diameter end of the taper is provided with the tool withdrawal groove, a locknut can be continuously screwed into the large-diameter end of the adapter sleeve, and further, a better fastening effect is achieved, a transmission shaft is prevented from axially drifting, the equipment maintenance frequency is reduced, and the maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of adapter sleeve, and particularly a kind of adapter sleeve that is used for tube mill belongs to the mechanical parts technical field.
Background technique
The transmission shaft of tube mill is provided with 4 bearings, locatees with 4 adapter sleeves.According to the positioning principle of adapter sleeve, during locking nut screwing, locking nut extruding bearing; Thereby make the relative displacement of generation between bearing and the adapter sleeve; Displacement is big more, and the effect of tightening is good more, so this theoretically assembling form position of rigid bearing effectively.But when locking nut is screwed to; Correcting for a short time 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 big end motion of adapter sleeve; So just can not fastening more fully bearing, so axial float has just taken place.
The model utility content
The utility model purpose is for the deficiency that overcomes existing technology a kind of adapter sleeve that can effectively prevent transmission shaft generation axial float to be provided.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of adapter sleeve comprises the adapter sleeve body; One end of said adapter sleeve body is provided with tapering, and the other end is provided with screw thread; Said screw thread links to each other with the miner diameter end of tapering; The miner diameter end of said tapering is provided with tool withdrawal groove.
Preferably, said tool withdrawal groove is an arc.
Preferably, the radius of said arc tool withdrawal groove is 5mm.
Preferably, said tapering is 1:12.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The adapter sleeve of the utility model because the miner diameter end of tapering is provided with tool withdrawal groove, guarantees that locking nut can continue to be screwed into toward the bigger diameter end of the utility model; 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 the utility model technological scheme is described further:
Accompanying drawing 1 is the stereogram of the adapter sleeve of the utility model;
Accompanying drawing 2 is the user mode figure of the adapter sleeve of the utility model;
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 and specific embodiment the utility model is done further to specify.
The described a kind of adapter sleeve of the utility model shown in accompanying drawing 1 comprises adapter sleeve body 1; One end of said adapter sleeve body 1 is provided with tapering 2, and the other end is provided with screw thread 3; Said screw thread 3 links to each other with the miner diameter end of tapering 2; The miner diameter end of said tapering 2 is provided with tool withdrawal groove 4; Said tool withdrawal groove 4 is an arc; The radius of said arc tool withdrawal groove 4 is 5mm; Said tapering 2 is 1:12.
Shown in accompanying drawing 2, during assembling, at first adapter sleeve body 1 is enclosed within on the transmission shaft 5, then bearing 6 is enclosed within on the adapter sleeve body 1, the miner diameter end of the tapering 2 on its end and the adapter sleeve body 1 aligns, and at last locking nut 7 is screwed into from screw thread 3 ends.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The adapter sleeve of the utility model because the miner diameter end of tapering is provided with tool withdrawal groove, guarantees that locking nut can continue to be screwed into toward the bigger diameter end of the utility model; Thereby reach better fastening effect; Prevent transmission shaft generation axial float, reduced the device maintenance number of times, reduced maintenance expenses and cost.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
