Abstract
The invention provides an elastic pin coupling which comprises a half coupling body, a flange hole formed in the half coupling body, a pin and a fastening device on the half coupling body. The improved elastic pin coupling has the advantages that displacement in all directions and offset angles are limited to some extent, accordingly assembly accuracy and quality are ensured, rework possibility is reduced, and assembly working efficiency is improved.
Description
Technical field
What the present invention relates to is coupling mechanical field, specifically about a kind of elastic dowel pin shaft coupling.
Background technique
HL type elastic dowel pin shaft coupling is the pin utilizing some non-metallic elastic materials to make, and is placed in two half-coupling flange holes, realizes two half-couplings connect, to realize the connection of two half-couplings by pin; HL type elastic dowel pin shaft coupling is classified as standard GB/T 5014-85, is applicable to the transmission shaft of various mechanical coupling two coaxial line, is generally used for dynamic high low-speed motion frequently.Operating temperature is generally-20 ~+80 DEG C; Transmitting nominal moment of torsion is 40 ~ 20000N.m; Its elastic element selects nylon material as the material of pin, has trace to compensate two axial lines excursion capability; HL type elastic dowel pin shaft coupling is simple and reasonable for structure, easy to maintenance, two sides is symmetrical interchangeable, life-span is long, allow larger axial float, have buffering, damping, the performance such as wear-resisting, but its elastic component is operationally sheared, functional reliability is poor, be only applicable to require very low middling speed drive line, be not suitable for functional reliability and require higher operating mode.Owing to being rely on nylon pin to connect between HL elastic dowel pin shaft coupling two halves connection, then be connected without other part, usually by the coupling iron wire that assembles through axis hole through binding, easily separated in assembling, transport process, cause part lost; In addition, due to reasons such as manufacture, installation, stand under load distortion and temperature variation, when mounting and adjusting, be difficult to keep the strict precise alignment of diaxon, and all directions displacement existed to a certain degree and angle of declination, therefore, solve the problems of the technologies described above in assembly process, to ensure that it is at transhipment, the complete and transportation safety of part in assembly process, and the precision keeping it to assemble and assembly quality, it is one of research and development direction comparatively urgent in current HL type elastic dowel pin shaft coupling field.
Summary of the invention
For the defect of prior art, the invention provides a kind of elastic dowel pin shaft coupling, Complete coupling is linked to be firm one, to guarantee complete, the safety of product when transfer station, packaging, transport, and the precision keeping it to assemble and assembly quality.
Above-mentioned purpose of the present invention is realized by the feature of independent claims, and dependent claims develops the feature of independent claims with alternative or favourable mode.
Technological scheme of the present invention is: a kind of elastic dowel pin shaft coupling, comprising:
Half-coupling main body; The transmission of two coaxial lines is completed for various mechanical coupling;
Flange hole in half-coupling main body, for running through pin;
Pin, for connecting two half-coupling main bodys;
Securing means, for fastening two half-coupling main bodys;
Further, described securing means is provided with clamping bolt;
Further, described securing means is provided with flexible contact face;
From the above technical solution of the present invention shows that, compared with of the present invention with traditional elastic dowel pin shaft coupling, it has following advantage and useful effect:
1. the elastic dowel pin shaft coupling of improvement of the present invention is simple and reasonable for structure, easy to maintenance;
2. the assembly of the coupling of the whole series is linked to be firm one by the present invention, guarantee product when transfer station, packaging, safety in transport;
3. when the assembly of a whole set of coupling is when mounting and adjusting, securing means carries out firmly to coupling, keep the strict precise alignment of diaxon, and the displacement limited to a certain extent in all directions and angle of declination, thus ensure that its precision of assembling and quality, reduce the possibility of doing over again, improve the working efficiency of assembling.

Fig. 1 is embodiments of the invention apparatus structure schematic diagram, wherein:
1-half-coupling main body 1; 2-half-coupling main body 2; Flange hole in 3-coupling main body; 4-pin; 5-securing means; 6-clamping bolt.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further;
As Fig. 1 shows, preferred embodiment of the present invention, the elastic dowel pin shaft coupling of improvement comprises: the flange hole 3 in half-coupling main body 1, half-coupling main body 2, coupling main body, pin 4, securing means 5, clamping bolt 6; Wherein, some pins 4 are assemblied in the flange hole 3 of the some correspondences in coupling main body, thus connection half-coupling main body 1 and half-coupling main body 2; Thus complete its transmission process; The quantity of flange hole 3 and supporting pin 4 can set according to technological requirement; Securing means 5 keeps the relative position of half-coupling main body and parts assembling thereof to immobilize, and can regulate fastening degree by rotational fastener bolt 6, the flexible contact face of setting can producing balanced forces face.
Further, described securing means is provided with clamping bolt;
Further, described securing means is provided with flexible contact face;
In sum, elastic dowel pin shaft coupling in embodiments of the invention, by carrying out fastening to the coupling improved, realize being mounted with of this device, thus ensure that the assembly precision of this coupling in packaging, transport, process in place remains unchanged, reduce the possibility of again assembling, improve assembly quality and working efficiency; Therefore, the elastic dowel pin shaft coupling of the present embodiment is provided with the advantage in assembling, helps its function to be improved and give full play to.
Above specification word and accompanying drawing are only explanation of the invention and explanation, in any form the present invention be not construed as limiting and limit, scope of the present invention is as the criterion with claims, and all do not exceed the apparent amendment of present inventive concept, conversion and replacement scheme all within the scope of the present invention.
