Abstract
The invention relates to a coupling for transmitting torque between shafts, particularly to a suspended elastic pin gear type coupling. The suspended elastic pin gear type coupling comprises an input half coupling, an output half coupling and a connecting outer sleeve; the input half coupling is fixedly connected with the front end of the connecting outer sleeve; the head portion of the output half coupling is matched with an inner hole of the connecting outer sleeve in a sleeved mode; involution holes which are formed along the circumference are formed between the head portion of the output half coupling and the matching surface of the connecting outer sleeve; nylon pins are arranged inside the involution holes; the nylon pins are drum-shaped and the diameters of drums are gradually decreased from the middle to the two ends; meanwhile the profile of the outer circumferential surface of the head portion of the output half coupling is arc-shaped on the longitudinal section. The suspended elastic pin gear type coupling has the advantages of enabling the allowed deflection angle between the two half couplings to be increased due to the drum-shaped nylon pins, accordingly reducing the installing difficulty of a transmission shaft and enabling a spherical matching supporting surface to be used for transmission of a vertical suspension shaft due to the spherical matching supporting surface which is formed between an annular end cover and the output half coupling.
Description
Technical field
The present invention relates to a kind of coupling between centers transmission moment of torsion, specifically is a kind of outstanding upright spring column pin gear coupling.
Background technique
GB GB/T5015-85 discloses a kind of spring column pin gear coupling, its structure is to utilize several cylindrical nylon pins to place involutory hole between two half-couplings and the outer ring inner surface, by pin longitudinal shear strength transfer moment of torsion, realize that two half-couplings connect.The defective of this structure is: 1, this structure coupling transmission compensation diaxon relative displacement is less, and the node inclination angle has only 0.5 °, and transmission accuracy requires high, has increased installation difficulty; 2, this structure coupling only is applicable to the installation of coaxial line horizontal shafting, and the suspension operation can not vertically be installed.
Summary of the invention
Technical problem to be solved by this invention, the first provide a kind of and can be offset by the big transmission shaft of compensate for slower the outstanding upright spring column pin gear coupling that installation difficulty is little, the life-span is long; It two provides a kind of outstanding upright spring column pin gear coupling that can carry out transmission to the vertical hanging axle.
Vertical outstanding upright spring column pin gear coupling of the present invention includes input half connection that can be connected with input shaft, output half connection that can be connected with output shaft, the connection overcoat between input half connection and output half connection, and described input partly joins with to connect the overcoat front end fixedly connected; The described output partly head of connection cooperates suit with the endoporus that connects overcoat, and has the involutory hole along circumferential arrangement between output half head that joins and the fitting surface that connects overcoat, and the nylon pin is installed in the involutory hole; Described nylon pin be shaped as the cydariform that diminishes gradually to the two ends diameter from the centre, the profile of outer peripheral surface on the longitudinal section of simultaneously described output half syncranium portion is arc.
The fixedly connected annular end cap in the rear end of described connection overcoat, the endoporus front end of annular end cap contacts by the sphere cooperation with the axle journal root of output half connection, output half connection can be supported in relative swing in the several angle scope under the guiding of spherical simultaneously mutually with annular end cap.
Be provided with seal ring between the axle journal excircle of the endoporus of described annular end cap and output half connection.
Advantage applies of the present invention exists: 1, by the nylon pin of cydariform is set, increased the permission deflection angle between two and half, thereby reduced the installation difficulty of transmission shaft; 2, cooperate supporting surface by partly between the connection sphere being set at annular end cap with output, both satisfied the needs that the rotating shaft deflection angle changes, effective axially support is provided simultaneously, can be enough in the transmission of vertical hanging axle.

Fig. 2 is the A-A cross-sectional view of Fig. 1;
The installment state schematic representation that Fig. 3 is the present invention when output half connection and input partly join rotating shaft and deflect.
Embodiment
As shown in Figure 1 and Figure 2, should outstanding upright spring column pin gear coupling include that the input that can be connected with input shaft partly joins 1, the output that can be connected with output shaft partly joins 2, the connection overcoat 3 between input half connection and output partly join, described input partly joins 1 with to connect overcoat 3 front ends fixedly connected; Described output partly joins 2 head 21 and cooperates suit with the endoporus that connects overcoat 3, and has the involutory hole 4 along circumferential arrangement between the head that output half joins and the fitting surface that connects overcoat, and nylon pin 5 is installed in the involutory hole; Described nylon pin 5 be shaped as the cydariform that diminishes gradually to the two ends diameter from the centre, the profile of outer peripheral surface 22 on the longitudinal section of simultaneously described output half syncranium portion is arc.The fixedly connected annular end cap 6 in rear end that connects overcoat 3, the endoporus front end of annular end cap 6 partly joins 2 axle journal root with output and contacts by sphere 7 cooperations, output half connection can be supported in relative swing in the several angle scope under the guiding of spherical simultaneously mutually with annular end cap.When output shaft and input shaft have the skew of certain limit, as shown in Figure 3, because the effect of cydariform nylon pin 5 and sphere 7 allows input half connection partly to be associated in the certain limit with output and compensates, thereby reduced installation difficulty.Be provided with seal ring 8 between the axle journal excircle of the endoporus of described annular end cap 6 and output half connection, protect with the mating part to inside.
