Abstract
The utility model relates to a coupler for transmitting inter-shaft torque, in particular to a suspension erecting elastic post pin tooth type coupler, comprising an input hemi-joint, an output hemi-joint and a jointing outer sleeve; the input hemi-joint is fixedly connected with the front end of the jointing outer sleeve; the head of the output hemi-joint is matched and sleeved with an inner hole of the jointing outer sleeve; circumferentially arrayed jointing holes are formed between the matching faces of the head of the output hemi-joint and the jointing outer sleeve; nylon post pins are mounted in the jointing holes; each nylon post pin is shaped like in a drum shape of which the diameters from the middle to two ends are gradually reduced; and the profile of the outer peripheral face of the head of the output hemi-joint is arc in the longitudinal section. The drum-shaped nylon post pins are arranged to increase the allowable deflection angle between the two hemi-joints, so the mounting difficulty of a transmission shaft is reduced; and the spherical matching support face is arranged between an end cover and the output hemi-joint, so the suspension erecting elastic post pin touch type coupler is used in the transmission of a perpendicular suspension shaft.
Description
Technical field
The utility model relates to a kind of coupling for the between centers transmitting torque, specifically a kind of outstanding vertical elastic plug tooth-type coupler.
Background technique
GB GB/T5015-85 discloses a kind of elastic plug tooth-type coupler, its structure is to utilize several cylindrical nylon pins to be placed in the involutory hole between two half-couplings and outer ring inner surface, by pin longitudinal shear strength transfer moment of torsion, realize that two half-couplings connect.The defect of this structure is: 1, this structure shaft coupling transmission compensation diaxon relative displacement is less, and the node inclination angle only has 0.5 °, and transmission accuracy requires high, has increased installation difficulty; 2, this structure coupling is only applicable to the installation of coaxial line horizontal shafting, can not hang operation by right angle setting.
Summary of the invention
Technical problem to be solved in the utility model, the first provide a kind of and can be offset by the large transmission shaft of compensate for slower, the outstanding vertical elastic plug tooth-type coupler that installation difficulty is little, the life-span is long; It two is to provide and a kind ofly can carries out to the vertical hanging axle the outstanding vertical elastic plug tooth-type coupler of transmission.
Vertical outstanding vertical elastic plug tooth-type coupler of the present utility model 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 and connects the overcoat front end and be fixedly connected with; The described output partly head of connection coordinates suit with the endoporus that connects overcoat, and has the involutory hole along circumferential arrangement between output half head joined and the fitting surface that connects overcoat, and the nylon pin is installed in involutory hole; Described nylon pin be shaped as the cydariform diminished gradually to the two ends diameter from centre, the profile of outer peripheral surface on longitudinal section of described output half syncranium section is arc simultaneously.
The rear end of described connection overcoat is fixedly connected with an annular end cap, the endoporus front end of annular end cap coordinates and contacts by sphere with the axle journal root of output half connection, making to export half can, in relative swing in the several angle scope under the guiding of spherical, support simultaneously mutually with annular end cap.
Between the axle journal excircle of the endoporus of described annular end cap and output half connection, be provided with seal ring.
Advantage applies of the present utility model 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, by annular end cap, partly between connection, sphere being set with output, coordinate supporting surface, both met the needs that the rotating shaft deflection angle changes, effective axially support is provided simultaneously, can be for the transmission of vertical hanging axle.
The accompanying drawing explanation
Fig. 1 connects the cross section structure schematic diagram at overcoat place in the utility model embodiment;
Fig. 2 is the A-A cross-sectional view of Fig. 1;
The installment state schematic diagram that Fig. 3 is the utility model when output half connection and input partly join rotating shaft and deflect.
Embodiment
As shown in Figure 1 and Figure 2, should outstanding vertical elastic plug tooth-type coupler 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 join 1 with connect overcoat 3 front ends and be fixedly connected with; Described output partly joins 2 head 21 and coordinates suit with the endoporus that connects overcoat 3, and has the involutory hole 4 along circumferential arrangement between the head that output partly joins and the fitting surface that connects overcoat, and nylon pin 5 is installed in involutory hole; Described nylon pin 5 be shaped as the cydariform diminished gradually to the two ends diameter from centre, the profile of outer peripheral surface 22 on longitudinal section of described output half syncranium section is arc simultaneously.The rear end that connects overcoat 3 is fixedly connected with an annular end cap 6, the endoporus front end of annular end cap 6 partly joins 2 axle journal root with output and contacts by sphere 7 cooperations, making to export half can, in relative swing in the several angle scope under the guiding of spherical, support simultaneously mutually with annular end cap.When output shaft and input shaft have the skew of certain limit, as shown in Figure 3, due to the effect of cydariform nylon pin 5 and sphere 7, allow input half connection partly to be associated in certain limit and to compensate with output, thereby reduced installation difficulty.Between the axle journal excircle of the endoporus of described annular end cap 6 and output half connection, be provided with seal ring 8, protect with the mating part to inner.
Claims (3)
1. one kind hangs vertical elastic plug tooth-type coupler, include input half connection (1) that can be connected with input shaft, output half connection (2) that can be connected with output shaft, the connection overcoat (3) between input half connection and output half connection, described input half joins (1) and connects overcoat (3) front end and be fixedly connected with; The described output partly head (21) of connection (2) coordinates suit with the endoporus that connects overcoat (3), and has the involutory hole (4) along circumferential arrangement between output half head joined and the fitting surface that connects overcoat, and nylon pin (5) is installed in involutory hole; It is characterized in that: described nylon pin (5) be shaped as the cydariform diminished gradually to the two ends diameter from centre, the profile of outer peripheral surface (22) on longitudinal section of described output half syncranium section is arc simultaneously.
