Abstract
A kind of diaphragm type large compensation shaft coupling, it is related to shaft coupling technical field, it includes input flange, connection flange, jackshaft, diaphragm unit and output flange, jackshaft left end is cased with input flange and connection flange, connection flange two sides are equipped with diaphragm unit, and copper sheathing and intermediate axis connection of the diaphragm unit on the right side of connecting flange by connection flange, copper sheathing is that gap is connect with jackshaft, the jackshaft right end is cased with output flange, and output flange is equipped with diaphragm unit.This diaphragm type large compensation shaft coupling passes through the radial position-limiting action of connection flange upper copper sheathing and jackshaft using at least three groups of diaphragm unit, angular deformation will not be generated, so that increased flexible member (diaphragm unit), the hinge in Shafting calculation will not be can be regarded as, solved the problems, such as since hinge is excessive unstable.
Description
Technical field:
The utility model relates to shaft coupling technical fields, and in particular to a kind of diaphragm type large compensation shaft coupling.
Background technique:
Diaphragm coupling is a kind of all-metal flexible coupling, it passes through elastic element --- diaphragm unit is by driving machine institute
The torque of generation passes to driven machine, and compensates all kinds of deformations of unit.With the development of drive technology, the high property of high torque large compensation
The demand of energy diaphragm coupling is constantly reinforced.Therefore, it needs to develop novel diaphragm coupling coupling structure, to increase shaft coupling
Compensation ability.
One group is generallyd use in previous diaphragm coupling structure design or two groups of diaphragm units are compensated as flexible member
Element.As the development and marine engine elasticity installation requirement of drive technology are increasing, large compensation high-performance membranous disc is joined
The demand of axis device is constantly reinforced.For the compensation ability for increasing shaft coupling, it usually needs increase diaphragm group in flexible coupling element
The outer diameter of part much applications limitation can not can use the shaft coupling of big outer diameter diaphragm unit structure, this just needs us logical
Cross the compensation ability for increasing flexible member quantity to increase shaft coupling.In carrying out dynamics calculation, diaphragm unit can be reduced to
One can produce angular and axial deformation hinge.If designing three groups or more multiple groups diaphragm using traditional structure connection
The shaft coupling of component, then the shafting where shaft coupling will appear since hinge excessively has shakiness when carrying out Shafting calculation
It is qualitative, cause entire shafting that can not pass through Shafting calculation.
Utility model content:
The purpose of this utility model is to overcome above-mentioned the shortcomings of the prior art places, and provide a kind of diaphragm type
Large compensation shaft coupling, it uses three groups or more group diaphragm unit structure types, while can keep the Shafting calculation mould of two angle points
Type；In the case where not increasing shaft coupling outer diameter, increase 50% or more nose balance ability；With low axial force to reduce axis
Carry lotus.
The technical solution adopted in the utility model are as follows: a kind of diaphragm type large compensation shaft coupling, including input flange, attached method
Orchid, jackshaft, diaphragm unit and output flange, jackshaft left end are cased with input flange and connection flange, and connection flange two sides are equal
Copper sheathing and intermediate axis connection, copper sheathing and centre of the diaphragm unit by connection flange equipped with diaphragm unit, on the right side of connecting flange
Axis is gap connection, and the jackshaft right end is cased with output flange, and output flange is equipped with diaphragm unit.
The diaphragm unit is at least three groups
The beneficial effects of the utility model are: this diaphragm type large compensation shaft coupling, logical using at least three groups of diaphragm units
The radial position-limiting action for crossing connection flange upper copper sheathing and jackshaft, will not generate angular deformation, so that increased flexible member
Part (diaphragm unit), will not can be regarded as the hinge in Shafting calculation, solve the problems, such as since hinge is excessive unstable.
Detailed description of the invention:
Fig. 1 is the utility model structure diagram.
Specific embodiment:
Referring to Fig.1, a kind of diaphragm type large compensation shaft coupling, including input flange 1, connection flange 2, jackshaft 4, diaphragm group
Part 5 and output flange 6,4 left end of jackshaft are cased with input flange 1 and connection flange 2, and 2 two sides of connection flange are equipped with diaphragm group
The diaphragm unit 5 of part 5,2 right side of connecting flange is connect by the copper sheathing 3 of connection flange 2 with jackshaft 4, copper sheathing 3 and jackshaft 4
For gap connection, 4 right end of jackshaft is cased with output flange 6, and output flange 6 is equipped with diaphragm unit 5.The diaphragm
Component 5 is at least three groups.
This shaft coupling left end increases by one group of diaphragm unit 5 compared with right end, increases nose balance ability, this group of diaphragm unit 5
By the radial position-limiting action of copper sheathing 3 and jackshaft 4 in connection flange 2, radial deflection will not be generated, which will not
Angular deformation occurs, so that two groups of left end flexible member (diaphragm unit 5) will not generate buckling deformation.Therefore, this shaft coupling into
Two hinge shaft coupling forms can be still reduced to when row Shafting calculation；In addition, since increased one group of diaphragm unit 5 will carry out axial direction
Compensation deformation, so the cooperation of the copper sheathing 3 and jackshaft 4 should be clearance fit, but gap width cannot be excessive.
This shaft coupling left end increases by one group of diaphragm unit compared with right end, increases nose balance ability, this group of diaphragm unit 5 is logical
The radial position-limiting action for crossing the copper sheathing 3 and jackshaft 4 in connection flange 2, will not generate radial deflection, which will not
Angular deformation occurs, so that two groups of left end flexible member will not generate buckling deformation.
In conclusion this diaphragm type large compensation shaft coupling, is passed through in connection flange 2 using at least three groups of diaphragm units 5
The radial position-limiting action of copper sheathing 3 and jackshaft, will not generate angular deformation, so that increased flexible member (diaphragm group
Part), the hinge in Shafting calculation will not be can be regarded as, solved the problems, such as since hinge is excessive unstable.
