A kind of barreled tooth flank hydrocoupling
Technical field
This utility model is related to coupler structure technical field, especially relates to ship hydrocoupling construction applications,
It is specially a kind of barreled tooth flank hydrocoupling.
Background technology
For being typically with flange or keyway connection, the connection of this kind of structure coupling between the industry axle such as ship and axle
Mode manufacturing cost is higher, and needs the diameter increasing the axle connection end connecting otherwise to be easily caused the fracture of axle, and therefore it makes
Also relatively difficult with installing;In order to solve above-mentioned technical problem, also occur in that using straight-tooth hydrocoupling in the art at present
To realize the connection between axle and axle, but straight-tooth hydrocoupling tooth easily when axle occurs crooked or skew in use
The even stuck problem of end edge, leads to shaft coupling to be scrapped.
Utility model content
For the problems referred to above, this utility model provides a kind of barreled tooth flank hydrocoupling, and it can solve existing straight-tooth liquid
Easily there is the even stuck problem of increment edge in pressure shaft coupling.
Its technical scheme is, a kind of barreled tooth flank hydrocoupling, and it includes inner sleeve, overcoat, flange sleeve and assembly and disassembly flange,
Described overcoat is pressed on periphery and the inner peripheral surface of described overcoat and the tapered cooperation of the outer circumference surface of inner sleeve of described inner sleeve,
The endoporus of described inner sleeve is isometrical circular hole, and the periphery of described overcoat is provided with external tooth, and the inner circumferential of described flange sleeve is provided with interior straight-tooth,
The flange end of described flange sleeve be fastenedly connected with described assembly and disassembly flange coaxial it is characterised in that: described external tooth is the flank of tooth in ball
The barreled tooth flank in face and sphere centre is on Gear axis, described flange sleeve is placed on described overcoat periphery and described interior straight-tooth
With the cooperation of described barreled tooth flank.
Further, the tooth top of barreled tooth flank of described overcoat periphery and two flanks make circular arc chamfering.
Further, sealed by o shape sealing ring between described flange sleeve and overcoat, described outer putting is additionally provided with tooth
Wheel back-up ring.
Further, the inner peripheral surface of described overcoat is provided with screw thread shape oil groove, the body of described overcoat offers and passes through
Wear described body the hydraulic fluid port with described screw thread shape oil groove UNICOM, described hydraulic fluid port after the hydraulic oil between inner sleeve and overcoat unloads
By locked spacer and silently screw sealing.
Further, sealed by o shape sealing ring between the axial connection end of described flange sleeve and described assembly and disassembly flange.
Further, screw, copper wire peace are passed through in described assembly and disassembly flange and the axis hole end of the connecting side of described flange sleeve
Equipped with cover plate.
The beneficial effects of the utility model are: the external tooth of the overcoat due to matching with the interior straight-tooth of flange sleeve inner circumferential
For the spherical barreled tooth flank of the flank of tooth, thus the admissible angular displacement of barreled tooth flank hydrocoupling more existing straight-tooth hydrocoupling is more
Greatly, thus the increment edge that produces or stuck phenomenon, the use of prolongation shaft coupling because axle crooked or skew can be prevented effectively from
Life-span;In addition, barreled tooth flank can be effectively improved and the interior straight-tooth of flange sleeve inner circumferential between under the conditions of permissible angle of heel degree
Contact conditions, improve the ability of transmitting torque, bearing capacity more existing straight-tooth hydrocoupling under identical working condition
Higher, thus also extending the service life of connection hydrocoupling further;And it can increase the axiality that connection two axle allows
Error, reduces and installs superior requirement, be easily installed use.

Specific embodiment
See Fig. 1 and Fig. 2, a kind of this utility model barreled tooth flank hydrocoupling, it includes inner sleeve 1, overcoat 2, flange sleeve 3
With assembly and disassembly flange 4, overcoat 2 is pressed on the periphery of inner sleeve 1 and the inner peripheral surface of overcoat 2 is tapered with the outer circumference surface of inner sleeve 1
Cooperation, the endoporus of inner sleeve 1 is isometrical circular hole, and the periphery of overcoat 2 is provided with external tooth, and external tooth is for the spherical barreled tooth flank 21 of the flank of tooth 22 simultaneously
And sphere centre is on Gear axis, and the tooth top of barreled tooth flank 21 and two flanks make circular arc chamfering, flange sleeve 3 interior
It is provided with interior straight-tooth 31 week, flange sleeve 3 is placed on overcoat 2 periphery and interior straight-tooth 31 is coordinated with barreled tooth flank 21, the method for flange sleeve 3
Lan Duanyu assembly and disassembly flange 4 passes through bolt 13, nut 16 is coaxially fastenedly connected.
Sealed by o shape sealing ring 7 between flange sleeve 3 and overcoat 2, overcoat 2 is additionally provided with gear back-up ring 10;Overcoat
2 inner peripheral surface is provided with screw thread shape oil groove 23, the body of overcoat 2 offers run through body and with screw thread shape oil groove 23 UNICOM
Hydraulic fluid port 24, between inner sleeve 1 and overcoat 2 hydraulic oil unloading after hydraulic fluid port 24 pass through locked spacer 5 and silently screw 11 seal;
Sealed by o shape sealing ring 8 between the axial connection end of flange sleeve 3 and assembly and disassembly flange 4;Assembly and disassembly flange 4 and flange sleeve 3
Screw 14 is passed through in the axis hole end of connecting side, copper wire 17 is provided with cover plate 6, and it is close that o shape circle is passed through in cover plate 6 and assembly and disassembly flange 4 end
Envelope;The other end of assembly and disassembly flange 4 passes through bolt 12, nut 15 is connected with axle;Screw 18, stop are also equipped with flange sleeve 3
Pad 19.
Operation principle of the present utility model is: hydraulic oil is squeezed into cone between inner sleeve 1 and toothed overcoat 2 from hydraulic fluid port 24 by it
Moved with specific purpose tool overcoat 2 in face screw thread shape oil groove 23 and in inner sleeve 1, shed between inner-outer sleeve after moving on to design attitude
Hydraulic oil, seals hydraulic fluid port 24 by locked spacer 5 and silently screw 11, so that overcoat 2 is pressed in inner sleeve 1, inner sleeve 1 is pressed on axle
On, transmitting torque from shaft uploads to inner sleeve 1, then passes to overcoat 2, by the external tooth on overcoat 2, moment of torsion is passed to straight-tooth flange sleeve in band
On pipe 3, then spread out of by bolt and assembly and disassembly 4 moments of torsion of flange.
