Abstract
The utility model relates to a distance variable shaft coupler with a large rotation angle, which comprises two connection flanges. The inner sides of the two connection flanges are uniformly provided with a fixed cylinder body, the inner bottom of the cylinder body is provided with a spherical surface-shaped trough, a middle driving shaft is arranged, and both ends of the middle driving shaft are provided with hemispherical shaft heads respectively matched with the spherical surface-shaped troughs on the inner bottom of the two cylinder bodies, an effective clearance is reserved between the outer circle of the middle driving shaft and inner walls of the two cylinder bodies, an axial long keyway which is arranged on the middle driving shaft is matched with a key, and the key is arranged in a slot hole on the end part of the cylinder body and is supported by a spring. The shaft coupler can simultaneously carry out rotation driving and axial movement driving, change the distance between the rotation angle of a driving shaft line and the connection flanges, increase the rotation angle of the driving shaft line and enlarge use range.
Description
The utility model relates to a kind of coupling, but particularly a kind of coupling of big corner displacement.
In the prior art, the coupling that can change transmission shaft line angle degree has spherical coupling, universal transmission coupling, cross transmission coupling etc., the hard-over of transmission axis is generally 15 degree during their transmissions, and the spacing between the flange connector at coupling two ends is changeless, give to install and propose higher requirement, and the corner that can only determine when installing is rotated transmission, can not move axially transmission and change transmission axis corner at any time, thereby limit its using scope.
But the purpose of this utility model is to provide a kind of big corner displacement coupling, can be rotated transmission simultaneously and move axially transmission, and can change the spacing between transmission axis corner and the change flange connector, increases transmission axis corner.
For achieving the above object, the utility model adopts following technical proposals:
But a kind of big corner displacement coupling comprises two flange connectors, it is characterized in that all there is fixing cylindrical shell two flange connector inboards, and there is the sphere connected in star at the end in the cylindrical shell; An intermediate propeller shaft is arranged, its two ends have the hemisphere spindle nose respectively with two cylindrical shells in end sphere connected in star be complementary; Leave the effective clearance between intermediate propeller shaft cylindrical and two cylinder inboard walls, axial long keyway and key coupling is arranged on the intermediate propeller shaft, key is placed in the slotted eye of cylindrical shell end and by spring-loaded.
The two ends of above-mentioned intermediate propeller shaft respectively have 2～4 circumferential uniform axial long keyway to be complementary with the key of same number respectively.
Above-mentioned key is the bulb-type round key, is plugged in the radially pin-and-hole of cylindrical shell end, and inner by spring-loaded, the spring outer end is supported by plug screw.
There is convex shoulder the hemisphere spindle nose at above-mentioned intermediate propeller shaft two ends and intermediate propeller shaft body joint.
Two above-mentioned cylindrical shells are made one with two flange connectors respectively.
The utility model compared with prior art, have following conspicuous characteristics and advantage: two flange connectors of the present utility model realize connecting transmission by ballhead round key and intermediate propeller shaft, the ballhead round key can be in long keyway axial slip, thereby the spacing between two flange connectors can change; Leave the effective clearance between intermediate propeller shaft cylindrical and the cylinder inboard wall, thereby can arbitrarily change transmission axis corner, its hard-over can reach 60 degree, much larger than the corner of prior art; Owing to can change corner and can be axially displaced arbitrarily, thereby can be rotated transmission simultaneously and move axially transmission, enlarge its using scope.
Accompanying drawing is an embodiment's of the utility model a structural representation.
An optimum implementation of the present utility model is: referring to accompanying drawing, but this big corner displacement coupling includes 1,10, two flange connector 1,10 inboards of two flange connectors fixing cylindrical shell 4,13 is arranged all,, there is sphere connected in star 2,11 at the end in the cylindrical shell 4,13; An intermediate propeller shaft 9 is arranged, and its two ends have hemisphere spindle nose 3,12 to be complementary with two cylindrical shells, 4,13 interior end sphere connected in star 2,11 respectively; Leave the effective clearance between intermediate propeller shaft 9 cylindricals and two cylindrical shells, 4,13 inwalls, have axial long keyway 8,17 and key 7,16 to be complementary on the intermediate propeller shaft 9, strong 7,16 are placed in the slotted eye of cylindrical shell 4,13 ends and by spring 6,15 supportings.The two ends of intermediate propeller shaft 9 respectively have 2 circumferential uniform axial long keyway 8,17 to be complementary with 2 keys 7,16 respectively.Key 7,16 is the bulb-type round key, is plugged in the radially pin-and-hole of cylindrical shell 4,13 ends, and inner by spring 6,15 supportings, spring 6,15 outer ends are by plug screw 5,14 supportings.There is convex shoulder the hemisphere spindle nose at intermediate propeller shaft 9 two ends (3,12) and intermediate propeller shaft body joint, prevent that intermediate propeller shaft 9 from pulling out from cylindrical shell 4,13.Two cylindrical shells 4,13 are made one with two flange connectors 1,10 respectively.
