Abstract
The invention discloses a slope matching shaft fixing device. The slope matching shaft fixing device comprises an inner sleeve and an outer sleeve. The outer surface of the inner sleeve and the inner surface of the outer sleeve are connected in a sleeved mode through matching between slope surfaces, and the axial length of the slope surface of the inner sleeve is larger than the axial length of the slope surface of the outer sleeve. A crack is formed in the inner sleeve in the axial direction, an annular key groove is formed in the small-gradient end of the inner sleeve, an annular fastener is arranged in the key groove, at least one threaded hole is formed in the fastener in the axial direction, and a bolt is arranged in each threaded hole. Compared with the prior art, the slope matching shaft fixing device has the advantages that a cylindrical shaft and a mechanical component fixed to the cylindrical shaft can be effectively prevented from making relative circumferential movement, production cost is low, and the strength of the cylindrical shaft cannot be reduced.
Description
Technical field
The present invention relates to a kind ofly for the mechanical components such as gear, belt wheel are fixed on to the fixing device on columniform axle, relate in particular to a kind of slope fitted shaft fixing device.
Background technique
The mechanical components such as existing gear, belt wheel are fixed on columniform axle by key and keyway conventionally, make the mechanical components such as gear, belt wheel follow columniform axle to rotate together, can effectively avoid the mechanical components such as gear, belt wheel, with columniform axle, relative circumferential movement occurs.
But, this means of fixation need to be on columniform axle and the mechanical component such as gear, belt wheel on process keyway, on the one hand, increased processing cost, on the other hand, reduce to a certain extent the mechanical strength of the mechanical components such as columniform axle and gear, belt wheel, shortened their working life.
So it is large to design a kind of join strength, and become product cost low, and can not reduce the shaft fixing device of the intensity of columniform axle.
Summary of the invention
The problems referred to above that the present invention need to solve are that not only processing cost is high for above-mentioned prior art, the deficiency that also can cause the mechanical strength reduction of the mechanical components such as columniform axle and gear, belt wheel, and provide a kind of processing cost low, and can not cause the slope fitted shaft fixing device of the mechanical strength reduction of the mechanical components such as columniform axle and gear, belt wheel.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of slope fitted shaft fixing device, comprise inner sleeve and outer sleeve, the internal diameter of described inner sleeve and the diameter of columniform axle are suitable, the external diameter of described outer sleeve is suitable with the diameter of axis hole that need to be fixed on the mechanical component on columniform axle, the length of described inner sleeve is greater than the length of described outer sleeve, the outer surface of described inner sleeve and the internal surface of outer sleeve are socketed by domatic cooperation, and the domatic axial length of described inner sleeve is greater than the domatic axial length of described outer sleeve; On described inner sleeve, be axially arranged with one crack, in one end of described inner sleeve light grade, be provided with an annular keyway, in keyway, be provided with an annular fastening piece, the internal diameter of described fastening piece and the diameter of keyway are suitable, on described fastening piece, be axially at least provided with a tapped hole, in tapped hole, be provided with bolt.
Described fastening piece is jump ring.
The degree of depth of described keyway is less than or equal to the thickness of 1/2nd inner sleeve wall.
On described fastening piece, be axially arranged with three tapped holes, and three described tapped hole annulars are distributed on fastening piece, in tapped hole, are respectively equipped with bolt.
The width of described keyway equals the width of fastening piece.
Compared with prior art, the invention has the beneficial effects as follows: because the outer surface of described inner sleeve and the internal surface of outer sleeve are socketed by domatic cooperation, and on described inner sleeve, be axially arranged with one crack, the thrust to outer sleeve by the bolt on fastening piece again, outer sleeve is further strengthened the coupling mechanism force of inner sleeve, can effectively avoid columniform axle to occur relative to circumferentially moving with the mechanical component being fixed on columniform axle, cost of production is low simultaneously, also can not reduce the intensity of columniform axle.
Accompanying drawing explanation
Fig. 1 is the structural representation of slope of the present invention fitted shaft fixing device;
Wherein, 1, inner sleeve, 2, outer sleeve, 3, crack, 4, keyway, 5, fastening piece, 6, bolt.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of slope fitted shaft fixing device, comprise inner sleeve 1 and outer sleeve 2, the described internal diameter of inner sleeve 1 and the diameter of columniform axle are suitable, the external diameter of described outer sleeve 2 is suitable with the diameter of axis hole that need to be fixed on the mechanical component on columniform axle, the length of described inner sleeve 1 is greater than the length of described outer sleeve 2, the outer surface of described inner sleeve 1 and the internal surface of outer sleeve 2 are socketed by domatic cooperation, and the domatic axial length of described inner sleeve 1 is greater than the domatic axial length of described outer sleeve 2; On described inner sleeve 1, be axially arranged with crack 3 one, crack 3 can further be tightened up, in one end of described inner sleeve 1 light grade, be provided with an annular keyway 4, in keyway 4, be provided with an annular fastening piece 5, the internal diameter of described fastening piece 5 and the diameter of keyway 4 are suitable, on described fastening piece 5, be axially at least provided with a tapped hole, in tapped hole, be provided with bolt 6.
Described fastening piece 5 is jump ring, and because jump ring has an opening, its internal diameter can expand to a certain extent, is easily installed in keyway 4.
The degree of depth of described keyway 4 is less than or equal to the thickness of 1/2nd inner sleeve 1 wall, and the degree of depth of keyway 4 is excessive, can reduce the intensity of inner sleeve 1.
On described fastening piece 5, be axially arranged with three tapped holes, and three described tapped hole annulars are distributed on fastening piece 5, in tapped hole, are respectively equipped with bolt 6, make outer sleeve 2 stressed evenly, be more conducive to 2 pairs of inner sleeves 1 of outer sleeve and add the uniform of the power of holding.
The width of described keyway 4 equals the width of fastening piece 5,, it is more suitable to make to coordinate, and can not produce and rock, and affects the uniform effect of thrust.
Compared with prior art, the invention has the beneficial effects as follows: because the outer surface of described inner sleeve and the internal surface of outer sleeve are socketed by domatic cooperation, and on described inner sleeve, be axially arranged with one crack, the thrust to outer sleeve by the bolt on fastening piece again, outer sleeve is further strengthened the coupling mechanism force of inner sleeve, can effectively avoid columniform axle to occur relative to circumferentially moving with the mechanical component being fixed on columniform axle, cost of production is low simultaneously, also can not reduce the intensity of columniform axle.
