Abstract
The utility model discloses a kind of connecting shaft cover, its drip irrigation device is: comprise cylindric body, described body comprises center hole, two end faces and a side, and an end face of described body is provided with bump, another end face be provided with described bump with the use of depressed part.The utility model solves in prior art, relative sliding can occur, connecting unstable problem between adjacent connecting shaft cover when piling up.
Description
Technical field
The utility model relates to a kind of connecting sleeve, and in particular, it relates to a kind of connecting shaft cover.
Background technique
Connecting shaft cover is a vitals in mechanical design field, and connecting shaft cover is arranged on its protective action of countershaft in rotating shaft usually.Continuous frictional rotation is in, so just need to ensure lubrication fully between connecting shaft cover and rotating shaft because rotating shaft and connecting shaft are enclosed within the process of supporting the use.
In prior art, connecting shaft cover generally comprises cylindric body, and body comprises center hole, two end faces and a side.When connecting shaft cover uses, be typically employed between connecting shaft cover and rotating shaft and add lubricant oil, due to need lubricant oil to add to rotating shaft and connecting shaft overlap between inside contact surface on, so add toward inner again after when adding needing rotating shaft and connecting shaft cover to split, whole process is loaded down with trivial details, brings great inconvenience to user.
Secondly, an inwall normally continuous surface of connecting shaft cover of the prior art, so it is larger with the surface of contact between rotating shaft to connect sleeve lining, thus cause rotating shaft in the process of self pivotable, connecting shaft cover is also larger with the wearing and tearing of rotating shaft.
Moreover two end faces of connecting shaft cover of the prior art are generally planes, so when being superimposed by some connecting shaft covers, end face between adjacent connecting shaft cover contacts with each other, because end face is plane, so can relative sliding be there is between adjacent connecting shaft cover, connect unstable.So, the problem just easily collapsed when connecting shaft cover warehouse-in is piled up time, if the problem collapsed, can make connecting shaft cover itself be damaged on the one hand, on the other hand, staff may be caused injured.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of connecting shaft cover, when this connecting shaft is enclosed within and piles up, not easily relative sliding occurs, stable connection.
For achieving the above object, the utility model provides following technological scheme: a kind of connecting shaft cover, comprise cylindric body, described body comprises center hole, two end faces and a side, an end face of described body is provided with bump, another end face be provided with described bump with the use of depressed part.
Preferably, the annular boss of described bump to be cross section be trapezoidal setting, described depressed part is cross section circular groove triangular in shape.
Preferably, described side is provided with the oil hole be communicated with described center hole.
Preferably, the sidewall of described center hole is provided with the inner groove be communicated with described oil hole.
Preferably, described oil hole is counter sink, and the bigger diameter end of described oil hole is positioned at the outside of miner diameter end.
The utility model has following advantage: an end face of connecting shaft cover of the present utility model is provided with bump, another end face be provided with bump with the use of depressed part, when piling up connecting shaft cover, the bump of adjacent connecting shaft cover can be made to coordinate with depressed part, and then make can not slide between adjacent connecting shaft cover, make its stable connection, prevent from piling up rear generation and the problem such as to collapse.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model connecting shaft cover.
In figure: 1, body; 11, center hole; 2, annular boss; 3, circular groove; 4, oil hole; 5, inner groove.
Embodiment
With reference to shown in accompanying drawing, the utility model connecting shaft cover is further illustrated.
Embodiment: a kind of connecting shaft cover, comprise cylindric body 1, body 1 comprises center hole 11, two end faces and a side, and an end face of body 1 is provided with bump, another end face be provided with bump with the use of depressed part.When piling up connecting shaft cover, adjacent connecting shaft cover is all piling up one by one from low to high, the bump of adjacent connecting shaft cover can be made to coordinate with depressed part by arranging like this, and then make can not slide between adjacent connecting shaft cover, make its stable connection, prevent from piling up rear generation and the problem such as to collapse.
Wherein, the annular boss 2 of bump to be cross section be trapezoidal setting, the effect that the annular boss 2 of such shape can bring is: on the one hand can form chamfering structure at the aperture place of center hole 11, makes rotating shaft can be convenient, laborsaving when insertion center hole 11; On the other hand, can chamfering structure be formed at the outward edge of body 1 end face, avoid sharp edge to produce the problems such as scuffing to workman.
Depressed part is cross section circular groove 3 triangular in shape, or in the trapezoidal setting suitable with annular boss 2, the circular groove 3 that in the present embodiment, preferred cross-sections is triangular in shape, such setting, because triangle is relative to trapezoidal easier machine shaping, further, when triangle and trapezoidal cooperation, its hypotenuse can both be fitted completely, makes both connect like this and has more stability.
Secondly, side is provided with the oil hole 4 be communicated with center hole 11, can add lubricant oil easily by arranging oil hole 4 in center hole 11, improves the convenience of adding lubricant oil, so just does not need axle sleeve and rotating shaft to disassemble to add lubricant oil.Oil filler plug can be set in the process of as installed and coordinate oil hole 4, by seal oil in connecting shaft cover.Further, oil hole 4 is counter sink, and the bigger diameter end of oil hole 4 is positioned at the outside of miner diameter end, and so, when installation oil filler plug, oil filler plug can be arranged in oil hole 4 completely, prevents oil filler plug from protruding from and connects boss surfaces.
Moreover the sidewall of center hole 11 is provided with the inner groove 5 be communicated with oil hole 4.Owing to being provided with inner groove 5 on the inwall of body 1, so lubricant oil can be stored in inner groove 5, make lubrication time more lasting.On the other hand, effectively reduce the area of contact of connecting shaft cover and rotating shaft by arranging inner groove 5, thus reduce this connecting shaft cover and the frictional force of rotating shaft, reduce the wearing and tearing of this connecting shaft cover, and improve the working life of this connecting shaft cover.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
