Abstract
The utility model discloses a novel expansion sleeve used for linkage. The novel expansion sleeve used for the linkage comprises an expansion sleeve body. An outer key groove used for being connected with a part key with a hole is formed in the outer surface of the expansion sleeve body, and an inner key groove used for being connected with a shaft key is formed in the inner surface of the expansion sleeve body. The novel expansion sleeve used for the linkage has the advantages of being simple in structure, good in centering performance, convenient to disassemble and assemble, reliable and stable in linkage, and capable of meeting the requirement for tight attachment among the expansion sleeve body, the outer key groove and the inner key groove, generating corresponding friction force and pressing force, being capable of preventing a sliding phenomenon or displacement from being generated among the expansion sleeve body, the outer key groove and the inner key groove and greatly increasing transmission quantity of torque, and therefore transmission is more continuous and reliable.
Description
Technical field
The utility model relates to component connection set field, is specially a kind of connection with novel swelling cover.
Background technique
In manufacturing mechanism, in the connecting of axial workpiece and the component that are complementary, the joining method of normal use is that flat key connects.The advantage that flat key connects: simple in structure, easy processing, easy to assembly, precision is not too high.So, generally considering that cost, processing and assembling easily under the situation, preferentially select for use key to connect.The shortcoming that flat key connects: the points of engagement that flat key connects generally has interference fit, excessive cooperation, Spielpassung, and the most frequently used be excessively and two kinds of Spielpassung (interference fit only is used in the place of specific (special) requirements), so often have the gap between axial workpiece and the component that match, under the situation of stress alternation and impact at intermittence and machine vibration, cause between axle and the component and produce axially, radially or compound moving, thereby the wearing and tearing of component take place, make the micro-gap change progressively that itself exists big, cause the fault and the damage of equipment.And if adopt universal swelling cover with axle and part close-coupled with holes to together, frictional force between dependence axle, expansion set, the part three and impacting force realize the transmission of moment, when moment during greater than the frictional force between the three, will produce skidding, abrasive damage takes place.
The model utility content
The purpose of this utility model is exactly the defective that exists at prior art, provides the reliable and stable connection of a kind of simple in structure, easy accessibility, connection with novel swelling cover.
The concrete technological scheme of the utility model is: comprise the swelling cover, the outer surface of swelling cover is provided with the outside keyway, the internal surface that are used for being connected with part key with holes and is provided with and is used for the interior spline that is connected with axle key.
Such scheme is more preferably: locking nut, the other end that an end suit of described swelling cover is used for fastening swelling cover and part with holes are provided with pressing plate, and uniform a plurality of on the described pressing plate are used for the stress bolt that is connected with part with holes.
The utility model is simple in structure, good to neutrality, easy accessibility, connection are reliable and stable, both can satisfy between the three and fit tightly, produce corresponding frictional force and impacting force, can prevent to produce between the three skidding or displacement again, increase the transmission capacity of moment greatly, make transmission more continuously, reliably.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, swelling cover, 2, external key, 3, internal key, 4, locking nut, 5, pressing plate, 6, stress bolt, 7, part with holes, 8, axle.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1, a kind of connection comprises swelling cover 1 with novel swelling cover, and the outer surface of swelling cover 1 is provided with outside keyway, internal surface is provided with interior spline; Threaded one end suit locking nut 4, the other end of swelling cover 1 are provided with pressing plate 5, the uniform a plurality of stress bolts 6 on the pressing plate 5.
Installation process is: at first swelling cover 1 is sleeved on the axle 8, and by internal key 3 swelling cover 1 is connected with axle 8; Then part 7 with holes is sleeved on the swelling cover 1, and swelling cover 1 is connected with part 7 with holes by external key 2; Then swelling overlap 1 one ends by the stress bolt on the pressing plate 56 be threaded with part 7 with holes, swelling simultaneously overlaps suit upper locking nut 4 on 1 the other end; During use, by screwing stress bolt 6, screwing locking nut 4 simultaneously, promptly can by swelling overlap 1 with axle 8 and part with holes 7 close-coupled to together, and fit tightly.
For those skilled in the art, under the prerequisite that does not break away from the utility model principle, might be to concrete size, perhaps partial structurtes are made some improvements and modifications, and these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. a connection is characterized in that with novel swelling cover: comprise the swelling cover, the outer surface of described swelling cover is provided with the outside keyway, the internal surface that are used for being connected with part key with holes and is provided with and is used for the interior spline that is connected with axle key.
2. connection according to claim 1 is with novel swelling cover, it is characterized in that: locking nut, the other end that an end suit of described swelling cover is used for fastening swelling cover and part with holes are provided with pressing plate, and uniform a plurality of on the described pressing plate are used for the stress bolt that is connected with part with holes.
