Description
Technical field
The present invention relates to a kind of shaft coupling, more particularly to a kind of oldham coupling.
Background technology
The oldham coupling of traditional form is typically made up of two half parts, and two half parts join with driving shaft and driven shaft respectively
Connect, be allowed to common rotation to transmit motion and torque.It is the corresponding radial direction in its both sides half a coupler end face using telophragma
Slided in groove, to realize that two half a couplers couple, and with two axle relative displacements of certain compensation, damping and shock-absorbing capacity.But
When being worked in the case that two between centers have relative displacement, telophragma will produce very big centrifugal force, so as to increase dynamic loading and
Abrasion, and the oldham coupling of traditional form is typically without angular compensation ability, oldham coupling in a conventional pattern be only applicable
In the occasion that rotating speed is very low, transmission moment of torsion is smaller and is required without angular compensatory.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it is an object of the invention to propose a kind of oldham coupling, have simultaneously
There is axial, radially and angularly deviation compensation ability, can be suitably used in middling speed and the mechanical driving device that part runs at high speed, tool
There is the characteristics of simple in construction, applied widely.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of oldham coupling, including left half a coupler 1 and right half a coupler 7, left half a coupler 1 is by bolt and commonly
Terminal pad 2 is fixedly connected, and generic connectivity disk 2 and the center of flower pattern gear hobbing 5 are equipped with screwing through hole and bolt hole, holding screw 3
Generic connectivity disk 2 is fixedly connected with flower pattern gear hobbing 5 with bolt hole by screwing through hole respectively with connecting bolt 4, flower pattern rolling
Tooth 5 with flower pattern groove terminal pad 6 is concentric installs, the teeth groove 9 of the strip-shaped tooth 8 in flower pattern gear hobbing 5 and flower pattern groove terminal pad 6, which coordinates, to be connected
Connect, flower pattern groove terminal pad 6 is fixedly connected by bolt with right half a coupler 7.
The quantity of the strip-shaped tooth 8 is six, is circumferentially separated by 60 ° and is evenly arranged.
The quantity of the teeth groove 9 is six, is circumferentially separated by 60 ° and is evenly arranged.
The diameter of the teeth groove 9 is more than the diameter of strip-shaped tooth 8.
It is connected due to of the invention using strip-shaped tooth with tooth socket fit, six strip-shaped tooths can freely radially slide in teeth groove,
So as to can realize radial missing compensate, meanwhile, flower pattern gear hobbing can be axially moveable in the teeth groove of flower pattern groove terminal pad or play,
Or along the certain angle of axis runout, make shaft coupling that there is the axially ability with tilting tolerance compensation；The present invention by flower pattern gear hobbing,
Generic connectivity disk is linked to be an entirety with left half a coupler, can move, avoid with driving shaft or driven shaft under working condition
The oldham coupling telophragma of traditional form produces the problem of big centrifugal force, therefore is applicable to middling speed and part runs at high speed
In device, there is the characteristics of simple in construction, applied widely.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the left view of flower pattern gear hobbing 5.
Fig. 3 is the left view of flower pattern groove terminal pad 6.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Referring to accompanying drawing 1, a kind of oldham coupling, including left half a coupler 1 and right half a coupler 7, left half a coupler 1 pass through
Bolt is fixedly connected with generic connectivity disk 2, and generic connectivity disk 2 and the center of flower pattern gear hobbing 5 are equipped with six screwing through hole and bolt
Through hole, holding screw 3 and connecting bolt 4 are respectively rolled generic connectivity disk 2 and flower pattern by six screwing through hole and bolt hole
Tooth 5 is fixedly connected, flower pattern gear hobbing 5 with flower pattern groove terminal pad 6 is concentric installs, the strip-shaped tooth 8 in flower pattern gear hobbing 5 is connected with flower pattern groove
The teeth groove 9 of disk 6 is connected, and transmits torque by contact surface, this arrangement makes power, torsion be evenly distributed, and transmits stable, flower
Type groove terminal pad 6 is fixedly connected by bolt with right half a coupler 7.
Referring to Fig. 2, the quantity of the strip-shaped tooth 8 is six, is circumferentially separated by 60 ° and is evenly arranged.
Referring to Fig. 3, the quantity of the teeth groove 9 is six, is circumferentially separated by 60 ° and is evenly arranged.The diameter of the teeth groove 9 is big
In the diameter of strip-shaped tooth 8.
The present invention operation principle be：
Left half a coupler 1 with right half a coupler 7 can optionally for one as active shafting, another be then driven shafting, works as master
The left half a coupler 1 of dynamic coupling of shaft system, motion and torque are passed into generic connectivity disk 2, due to flower pattern gear hobbing 5 and generic connectivity disk
2 are fastenedly connected and are integrated by holding screw 3 and connecting bolt 4, so the motion and torque of active shafting transmission are passed to
On the strip-shaped tooth 8 of flower pattern gear hobbing 5, strip-shaped tooth 8 is coordinated by the flank of tooth and the teeth groove 9 of flower pattern groove terminal pad 6, so transmit motion and
Torque, last flower pattern groove terminal pad 6 drive right half a coupler 7 to rotate by bolt, final output motion and torque.
Six strip-shaped tooths 8 can freely radially slide in teeth groove 9, so as to realize that radial missing compensates；Meanwhile flower pattern is rolled
Tooth 5 can in the teeth groove 9 of flower pattern groove terminal pad 6 axial movement or play or along the certain angle of axis runout, have axially and
The ability of tilting tolerance compensation.
