Abstract
The utility model discloses a shaft coupler. According to the shaft coupler, two combining sleeves are symmetrically arranged in inner holes of a cylinder sleeve; a cylinder cover is fixedly mounted at a large end hole part of the cylinder sleeve; a hydraulic medium is filled into a sealed space formed by the cylinder cover, the cylinder sleeve and the combining sleeves; friction discs are arranged between end surfaces of the two combining sleeves; friction pieces are fixedly riveted on two surfaces of the friction discs; inner ring gears are formed in the inner holes of the two combining sleeves; an arced tooth-shaped outer ring gear is arranged in each inner ring gear; the arced tooth-shaped outer ring gear is fixed at one end of a connecting shaft sleeve; an axial positioning plate is fixedly mounted at the outer end part of each combining sleeve. The shaft coupler has the advantages of higher transmission load, good position compensation capability between two connecting shafts, and overload protection function.
Description
Technical field
The utility model relates to a kind of coupling, belongs to machinery standard component technical field.
Background technique
At present, although coupling is not quite similar in structure and principle,, generally exist driven load lower, poor to the position compensation ability between two institute's coupling shafts, especially exist and there is no the defect of overload protection function.
Summary of the invention
The purpose of this utility model is: for the existing above-mentioned defect of existing coupling; the utility model provides a kind of novel coupling; this kind of novel coupler have driven load higher, the position compensation ability between two institute's coupling shafts better, is especially had to overload protection function, can overcome preferably the existing above-mentioned defect of existing coupling.
The utility model is realized the technological scheme that above-mentioned purpose adopts: described a kind of coupling, it comprises: connecting bushing, axially locating plate, ring gear, circle-arc tooth external toothing, combined cover, cylinder cap, hydraulic medium, friction plate, friction disk, cylinder sleeve, it is characterized in that: two combined covers are set symmetrically in the endoporus of cylinder sleeve, large port position at cylinder sleeve is mounted with cylinder cap, in the space that cylinder cap and cylinder sleeve and combined cover seal, be filled with hydraulic medium, between the end face between two combined covers, friction disk is set, the each riveted joint in two sides of described friction disk is fixed with friction plate, in the endoporus of two combined covers, be shaped with ring gear, in each ring gear, be provided with circle-arc tooth external toothing, described circle-arc tooth external toothing is circular arc type along facewidth direction, described circle-arc tooth external toothing is fixed on one end of connecting bushing, install and fix an axially locating plate at the external port position of each combined cover.
Beneficial effect: 1, transmit load by the intermeshing method of interior external toothing, have advantages of that driven load is higher, 2, between the end face between two combined covers, friction disk is set, the each riveted joint in two sides of friction disk is fixed with friction plate, not only have advantages of that friction torque is larger, simultaneously, in the time that transmitted load overloads, by the mutual slip between bonded block, reach the effect of overload protection, 3, because circle-arc tooth external toothing has the position regulation of certain limit at ring gear, thereby the position degree of the connecting bushing being attached thereto is also changed thereupon, so, the utility model also has the better advantage that obtains of the position compensation ability between two institute's coupling shafts, 4, be enclosed in the pressure that is filled with hydraulic medium in cylinder cap and cylinder sleeve and combined cover space by change, just can change two frictional force between combined cover, thereby change claimed load range, so, the utility model also has easy to use, the good advantage of applicability.
