Abstract
The invention discloses an elastic coupling for a spline shaft. The elastic coupling comprises a flange plate and a spline sleeve; a counter bore is formed in the flange plate; the spline sleeve consists of a plurality of annular metal sheets laminated together; the spline sleeve is tightly pressed in a sinking part of the counter bore by a pressing part, and is coaxial with the counter bore; and spline grooves are peripherally distributed in the inner wall of the spline sleeve. The elastic coupling has the technical effects of reduction of spline wear and capability of guaranteeing lower concentricity.
Description
Technical field
The present invention relates to shaft joint field, particularly relate to a kind of splined shaft elastic coupling flexible coupling.
Background technique
Coupling is used to two axles (driving shaft and driven shaft) connected in different institutions to be made it jointly to rotate with the mechanical parts of transmitting torque.Coupling is of a great variety, according to the Placement situation being connected diaxon, can be divided into: rigid coupling and elastic coupling flexible coupling.
In the transmission system of high frequency generator group, the splined shaft coupling usually can used splined shaft and coordinate with it.In conventional art, rigid coupling is widely used; On the rigidity spline housing of spline fitted on splined shaft on coupling, to ensure that between driving shaft and transmission shaft, concentricity is enough little when transmitting torque.But splined shaft can produce vibration in High Rotation Speed, this makes to have between spline and spline housing to clash into and occurs, and this also accelerates the wearing and tearing of spline greatly.
Because elasticity shaft joint is provided with elastic buffer structure, as offered spiral chute or parallel slot on coupling, and be that elastic coupling flexible coupling has the effect of buffering, vibration damping with the parts such as resilient pad or bellows at the connection part of coupling; If be used in by traditional elastic coupling flexible coupling in above-mentioned high frequency generator group, the problems referred to above can obtain part and solve; But due to the essence that this type of elasticity connects, allow for the relative movement between connected component, this just brings the problem (the accessible concentricity of traditional elastic coupling is 0.5-0.8 millimeter) that between driving shaft and transmission shaft, concentricity is excessive when transmitting torque, and the performance of this one side of traditional elastic coupling also needs further technological scheme to be solved.
Summary of the invention
The invention is intended to provide one can alleviate spline wearing and tearing, the splined shaft elastic coupling flexible coupling of less concentricity can be ensured again.
Splined shaft elastic coupling flexible coupling in this programme, comprise flange plate, spline housing, described flange plate has counterbore, described spline housing is multiple annular metal sheets overlapped together, the compacted compressing parts of this spline housing is coaxial with counterbore in the sinking portion of described counterbore, and on the inwall of spline housing, circumference is distributed with spline, this spline and the spline fitted needing to be connected in it.
Working principle and beneficial effect: need the splined shaft connected to be engaged in elastic coupling flexible coupling, the required parts be connected with this splined shaft can be fixed on flange plate; When the spline on splined shaft collides because the keyway on High Rotation Speed and spline housing produces, the annular metal sheet overlapped together is because have tiny gap, thus can absorb a part of kinetic energy and be converted to elastic potential energy via the file that annular metal sheet is small is each other dynamic, thus reach the effect of bumper and absorbing shock, alleviate the wearing and tearing of spline; , to laminate and the annular metal sheet be pressed in flange plate has characteristic close to rigid coupling meanwhile, can allow and connect two ends concentricity and be reduced in the scope of 02.-0.5 millimeter, solve the problem that traditional elastic concentricity of coupling is too high.
Further optimization, described fixed block is specially screw, and spline housing is pressed on the counterbore bottom surface of flange plate through the through hole of circumference distribution on described coupling by this screw; Screw is common part, such compression mode, simple, is convenient to installing/dismounting and cleaning, also adjusts by the compaction degree of form to described spline housing tightened or unclamp screw simultaneously.
Further optimization, the stacking factor of spline housing is more than or equal to 0.97, is less than 1.
Stacking factor herein refers to: the actual (real) thickness after the thickness summation/annular metal sheet of annular metal sheet laminates.
It can thus be appreciated that stacking factor is 1 to the maximum, namely thickness summation equals actual (real) thickness; Stacking factor is more than or equal to 0.97, annular metal sheet is laminated enough closely closely thus ensure that laminating rear spline housing has rigidity, and then concentricity enough little when ensureing shaft coupling transmission; Stacking factor is less than 1 and ensure that to there is tiny gap between annular metal sheet, can play the effect of buffering.
Further optimization, described annular metal sheet specifically can be the ring-type steel plate of 1 millimeters thick, and this type of ring-type steel plate is easy to processing, reduces the cost of production of described splined shaft elastic coupling flexible coupling.

Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: flange plate 1, spline housing 2, screw 3.
The present embodiment is as shown in Figure 1 and Figure 2: spline elastic coupling flexible coupling, comprise flange plate 1, spline housing 2 and screw 3, spline housing 2 is that the ring-type sheet pack of several 1 millimeters thick forces together, on each ring-type steel plate, circumference is distributed with through hole, the through hole that through hole time stacked on each ring-type steel plate is long to its formation, screw 3 through these long through holes to stretch on flange plate 1 open the bottom surface of counterbore, and be fixedly connected with flange plate 1 by the tapped hole on this bottom surface, whole spline housing 2 is pressed on flange plate 1 simultaneously; The stacking factor of spline housing 2 is with being 0.97, and in order to ensure the rigidity characteristic of spline housing 2, spline housing 2 inwall after compression forms several spline.
The present embodiment working procedure is as follows: need the splined shaft connected to coordinate in elastic coupling flexible coupling, the required parts be connected with this splined shaft can be fixed on flange plate 1; When the spline on splined shaft collides because the keyway in high speed turn and spline housing 2 produces, because there is tiny gap between the ring-type steel plate overlapped together, spline housing 2 can absorb a part of kinetic energy, and be converted to elastic potential energy via the file that ring-type steel plate is small is each other dynamic, thus reach the effect of bumper and absorbing shock, alleviate the wearing and tearing of spline; Laminate simultaneously and be pressed on the sufficiently high stacking factor of ring-type steel plate in flange plate 1, thus the characteristic close to rigid coupling is provided with, connection two ends concentricity can be allowed to be reduced in the scope of 02.-0.5, to solve the problem that traditional elastic concentricity of coupling is too high.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
