Description
The utility model belongs to the mechanical transmissioning technology field.
The movable coupling of present connection two lower velocity shafts that in mechanical industry, extensively adopt, it is installed compensation performance and mainly contains gear coupling (Q/ZB 104-73, Q/ZB105-73) preferably, pin coupler (Q/ZB 123-73), rod pin coupling (Q/ZB 231-74), and sliding cross coupling (seeing Chemical Industry Press's " mechanical design handbook " first volume second fascicle).Wherein the gear coupling bearing capacity is big, and using scope is wide, but is subjected to structural limitations, and its angle compensation maximum value is only spent with interior (30 ') half, exists processing to need Special Equipment simultaneously, and manufacturing technology is complicated, and Installation and Debugging are than deficiencies such as difficulties; The radially installation offset of sliding cross coupling is bigger, but the angular displacement that allows still 30 ' in, also there is the complicated shortcoming of manufacturing technology, and the bearing capacity of sliding cross coupling is less, using scope is restricted, rod (post) pin coupling simple in structure, easy to manufacture, bearing capacity is big, but still the shortcoming of compensation performance poor (α≤30 ') exist to be installed, and is subjected to the restriction of serviceability temperature (20 ℃～70 ℃).
In mechanical transmission, transmission of power between prime mover, transmission device and the working machine, all must realize by coupling, because each parts all has in various degree manufacturing and alignment error, and the distortion that causes because of load, temperature variation in the work etc., make coupled diaxon have in various degree coaxiality error inevitably, so require coupling to have certain installation compensation performance.
The purpose of this utility model, for overcoming the deficiency of above-mentioned coupling, a kind of comprehensive compensation performance of special development is good, bearing capacity is big, Installation and Debugging are easy.The movable self-alignment compensate coupling of rigidity easy to manufacture.
Structure of the present utility model is made up of (1) half-coupling, (2) lining, (5) forced filling oil cup, (6) circlip, (7) screw, (8) spring washer and (9) plain washer, standard piece (3) sphere Pivoting bearing and (4) eccentric pin shaft are adopted in design, or adopt (14) pull bar, (16) sphere Pivoting bearing and (18) bearing pin to constitute the self-alignment compensate coupling.Adopt many pull bars (pull bar is counted n 〉=3) between its two half-coupling, still connect between pull bar and the half-coupling by bearing pin and spherical hinge.Or self-alignment (floating) dish replaces pull bar in the middle of adopting between two half-couplings, middle self-alignment (floating) coil with two half-couplings between connect through bearing pin and spherical hinge realization.Or realize connecting along the sphere Pivoting bearing of packing in the eccentric pin shaft of packing in the uniform some holes of periphery and the corresponding hole of second half coupling by a half-coupling therein.Or, can between two cover coupling, add a middle floating axle respectively again with regard to above-mentioned several situations.
Technological points of the present utility model: bearing pin and sphere hinge are adopted in the connection between two coupling, when transmitting torque mainly by the standard sphere Pivoting bearing of high reliability and comprehensive mechanical performance preferably bearing pin be used as the operation element of power transmission, thereby can guarantee that coupling has higher reliability and long working life.
Structural behaviour of the present utility model and working principle:
1, embodiment one: shown in accompanying drawing 1, the self-alignment compensate coupling is mainly by two half-couplings (1), and sphere Pivoting bearing (3) and eccentric pin shaft (4) are formed.Two half-couplings that are evenly equipped with some holes along periphery connect by sphere Pivoting bearing (3) realization of packing in the eccentric pin shaft (4) of packing in all holes of a half-coupling therein and second half coupling respective aperture.Because the big end and the small end of bearing pin are eccentric, so have radially alignment error at coupled diaxon, and make two half-couplings along the corresponding aperture of circumferential distribution can not the situation of centering under, rotatable eccentric pin shaft, make two half-couplings do eccentric the connection, thereby can compensate the radially alignment error of diaxon to a certain extent.When coupled diaxon is installed under the situation of strict centering, also two half-couplings can be relatively rotated a minute angle, and rotate each eccentric pin shaft, the center of eccentric end is dropped on the center circle in all holes of half-coupling periphery that connect with it, and offset distance is along a direction, make two half-couplings along all corresponding apertures of circumferential distribution under eccentric relatively situation, can realize still connecting that (at this moment the gyration center of two half-couplings is still centering.See accompanying drawing 2).In addition, two half-couplings also can be realized relative deflection by Pivoting bearing (3), thereby can compensate the angle alignment error of coupled diaxon.Moreover, because Pivoting bearing (3) can be done play (adopting Spielpassung between the two) along the hole wall of lining (2), so have bigger axial displacement compensation ability.
2, embodiment 2: shown in accompanying drawing 3, the self-alignment compensate coupling mainly is made up of two half-couplings (10) pull bars (14), sphere Pivoting bearing (16) and bearing pin (18).The pull bar (14) that transmits peripheral force is for connecting the intermediate member of two half-couplings (10), its with two half-couplings between connect by bearing pin (18) and sphere Pivoting bearing (16) realization.Because the sphere Pivoting bearing is equipped with at the two ends of intermediate member pull bar (14) (this example is four), pull bar can be realized automatic positioning, so is installing and allowing two half-couplings to have certain relative angle of yaw during running, and coupling still can proper functioning, thereby compensate the angular error of coupled diaxon.
In embodiment 2, also available one whole middle self-alignment dish replaces pull bar, and its principle is seen simplified schematic diagram 5.Two half-couplings (20) are realized connecting with the sphere Pivoting bearing (23) in being contained in self-alignment dish (22) respective aperture by the some bearing pins (21) at its circumference uniform distribution, and its working principle is the same with the coupling shown in the accompanying drawing 3.In this case, the integral rigidity of coupling is quite a lot of, and manufacturing is installed easier, but offset slightly descends.
To above-mentioned each routine situation, according to actual requirement, also can be between two cover self-alignment compensate couplings, floating axle in the middle of adding one again, its compensation effect is better, the structure that adds jack shaft is seen schematic representation 6, and wherein (25) are that middle floating axle, (24) can be accompanying drawings 1, the self-alignment compensate coupling of several structural types such as accompanying drawing 3 and accompanying drawing 5.The structure of floating axle in the middle of this adding, its compensation ability is big, and is the most suitable for rotary kiln, the pebble mill of building material industry.
Advantage that the utility model is compared with prior art had and effect:
1, processing simple (not needing special device and very high technical merit), cost of production is low.According to different size, compare with the gear coupling that transmits same torque, about its cost low (1/2～1/3).
2, compensation performance is good, and the transmitting torque scope is big.Under installation and operating condition, coupled diaxon is had bigger comprehensive displacement compensation ability, especially the angle compensation value can reach 2 °～3 °.
3, installation, dismounting, debugging and easy to maintenance, to installation precision require low.
