Abstract
The invention provides an elastic coupling of a one-way precise diaphragm, which has the advantages of simple structure, low cost and capability of supporting large repeated fluctuating loads, impact loads and bending moment. An input flange and an output flange of the elastic coupling and the diaphragm between the input flange and the output flange are connected by bolts; an expansion sleeve consisting of an outer conical ring and an inner conical ring is arranged in shaft holes of an input shaft and an output shaft; the inner conical ring and the outer conical ring are cones which have radial notches and are unclosed in a circumferential direction; the outer peripheral surface of the inner conical ring and the inner peripheral surface of the outer conical ring are conical surfaces which are matched mutually; the elastic coupling also comprises two end covers which are respectively connected with the input shaft and the output shaft through the bolts in an axial direction; and compaction parts which extend into the shaft hole of the input shaft or the output shaft and are contacted with the end face of the expansion sleeve are arranged on the end cover, and when moving along the axial direction, the compaction parts push the inner conical ring or the outer conical ring to move axially and reduce the inner peripheral diameter of the inner conical ring.
Description
Technical field
The present invention relates to a kind of unidirectional accurate diaphragm elastic coupling flexible coupling.
Background technique
Unidirectional accurate diaphragm elastic coupling flexible coupling comprises that an end has output shaft, diaphragm that the input shaft of flange plate, an end have flange plate, is provided with diaphragm between input shaft flange plate and the output shaft flange plate; Input shaft flange plate links to each other by bolt with output shaft flange plate and the diaphragm between them.Input shaft and output shaft generally are hollow shaft, all have keyway on the inner hole wall.During use, input shaft links to each other with driving shaft by key, and output shaft links to each other with driven shaft by key, thereby the moment of torsion of driving shaft is passed to driven shaft.
But the structure that key connects, the ability of bearing alternate load and impulsive load is less, and the moment of flexure that input shaft and driving shaft (output shaft and driven shaft) can bear is also less.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, cheap, can bear the unidirectional accurate diaphragm elastic coupling flexible coupling of bigger alternate load, impulsive load and moment of flexure.
This unidirectional accurate diaphragm elastic coupling flexible coupling comprises that an end has the output shaft that the input shaft of flange plate, an end have flange plate, is provided with diaphragm between input shaft flange plate and the output shaft flange plate; Input shaft flange plate links to each other by bolt with output shaft flange plate and the diaphragm between them; It also comprises the expansion set of being made up of outer conical ring and interior conical ring in the axis hole that is arranged on input shaft and output shaft; Interior conical ring and outer conical ring all are to have the radially cone of circumferentially not sealing of notch, and the outer circumferential face of interior conical ring and the inner peripheral surface of outer conical ring are the conical surfaces that matches; It also comprise two axial direction respectively with input shaft and output shaft by bolted end cap; Have the contacted compressed part of the end face with expansion set in the axis hole that extend into input shaft or output shaft on the end cap, when compressed part was mobile vertically, interior conical ring of its promotion or outer cone annulate shaft were to mobile, and interior all diameters of conical ring reduce in making.
Beneficial effect of the present invention: during use, driving shaft (or driven shaft) is stretched in the axis hole of input shaft (or output shaft), then, regulate the bolt that connects end cap and input shaft (or output shaft), make compressed part on the end cap promote in conical ring or outer cone annulate shaft to moving, interior all diameters of conical ring reduce gradually in making, expansion set is just held tightly on driving shaft (or driven shaft) like this.Certainly, the outer circumference diameter of outer conical ring can subtract gradually greatly on the inner hole wall that is pressed on input shaft (or output shaft).The present invention connects by expansion set, produces pressure and frictional force between the conical surface of conical ring and outer conical ring in making, realizes load transfer.Input shaft is connected with driving shaft (output shaft and driven shaft) can self-alignment, the precision height; Can transmit bigger moment of torsion and axial force; Can bear alternate load and impulsive load; Can bear bigger moment of flexure with the less diameter of axle.

Embodiment
Unidirectional accurate diaphragm elastic coupling flexible coupling shown in Figure 1 comprises that an end has the output shaft 2 that the input shaft 1 of flange plate 11, an end have flange plate 21, is provided with diaphragm 3 between input shaft flange plate and the output shaft flange plate; Input shaft flange plate links to each other by bolt 5 with output shaft flange plate and the diaphragm between them.
Be respectively arranged with two expansion sets 6 in the axis hole of input shaft and output shaft.Expansion set comprises interior conical ring 61, outer conical ring 62, and interior conical ring is to have the radially cone of circumferentially not sealing of notch 63, and outer conical ring is to have the radially cone of circumferentially not sealing of notch 64.The outer circumferential face of interior conical ring and the inner peripheral surface of outer conical ring are the conical surfaces that matches.
Two end caps 7,8 are connected by bolt 9 with output shaft 2 with input shaft 1 respectively at axial direction; Has the contacted compressed part 71 of the end face with outer conical ring in the axis hole that extend into input shaft on the end cap 7.Has the contacted compressed part 81 of the end face with outer conical ring in the axis hole that extend into output shaft on the end cap 8.
When tighting a bolt 9, end cap 7 moves right vertically, and compressed part 71 promotes the outer cone annulate shafts to moving right, and makes the outer circumference diameter increase of outer conical ring 62, and interior all diameters of interior conical ring 61 reduce.Like this, the driving shaft that extend in input shaft 1 axis hole promptly couples together by expansion set 6 and input shaft.In like manner, when 9 end caps 8 that tight a bolt were moved to the left vertically, compressed part 81 promoted the outer cone annulate shafts to being moved to the left, and made the outer circumference diameter increase of outer conical ring 62, and interior all diameters of interior conical ring 61 reduce.Like this, the driven shaft that extend in output shaft 2 axis holes promptly couples together by expansion set 6 and output shaft.
