Abstract
The utility model relates to a damping type diaphragm shaft coupling. A connecting disk (6) is arranged between a middle shaft and two half shaft couplings, the inner ring surface of the connecting disk (6) is provided with a damping ring (7), and the middle shaft (3) cooperates with the damping ring (7) to form a vibration damping mechanism. Besides, when the middle shaft (3) rotates at high speed, vibration generated is lowered because of influence of the gravity of the middle shaft (3), and the damping ring can absorb and lighten the vibration generated by the rotation of the middle shaft, which can effectively lower noise.
Description
Technical field
The utility model relates to coupling, particularly diaphragm coupling.
Background technique
Diaphragm coupling includes two half-couplings, a jack shaft and the diaphragm that is separately positioned between two half-couplings and the jack shaft constitutes.Two half-couplings are installed in respectively on prime mover shaft and the working crankshaft when work, diaphragm by jack shaft and its both sides passes through one group of flexible connection of bolt between the two, because diaphragm has better elastic, prime mover shaft and working crankshaft can be compensated by the resiliently deformable of diaphragm within the specific limits owing to make and relative malalignment that alignment error causes, and the mechanical vibration of shaft coupling generation can be subdued to a certain extent.
The deficiency that the diaphragm coupling of this prior art exists is, because the action of gravity of jack shaft produces vibration inevitably, thereby increases the noise of whole mechanical system when high speed rotating.Therefore can not fully satisfy some have the occasion of being strict with or limiting to noise user demand.
The model utility content
The purpose of this utility model is to improve at above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, can effectively reduce the diaphragm coupling of noise.
The technical solution of the utility model is at jack shaft 3 and two half-couplings 1, set up vibration damping mechanism between 2, promptly at jack shaft 3 and two half-couplings 1, be provided with land 6 between 2, land 6 and half-coupling 1, the 2nd, one constitutes or is bolted to connection, land 6 inner ring surfaces are provided with damped ring 7, jack shaft 3 cooperates with damped ring 7, jack shaft 3 is subjected to the supporting of land 6 by damped ring 7 like this, the vibration that produced by himself gravity effect reduces, and damped ring 7 can absorb and alleviate the vibration that jack shaft 3 rotation produces, and experimental results show that and can reduce noise 5-10PB.
Description of drawings
Accompanying drawing is the utility model embodiment schematic representation.Its signal be land 6 and half-coupling the 1, the 2nd, be bolted to connection.
Embodiment
The utility model comprises half-coupling 1,2, jack shaft 3 and diaphragm 4,5, diaphragm the 4, the 5th, integrated type diaphragm or linkage type diaphragm, between jack shaft 3 and two half-couplings 1,2, be provided with land 6, land 6 and half-coupling the 1, the 2nd, one constitute or fixedly connected by bolt 8, diaphragm 4,5 is by fixedlying connected with jack shaft 3 with half-coupling 1,2 that bolt 9 intersects, land 6 inner ring surfaces are provided with damped ring 7, jack shaft 3 cooperates with damped ring 7, and promptly the axle head of jack shaft 3 stretches in the land 6 in the ring and damped ring 7 interference fit.Damped ring 7 is rubber ring, nylon ring, and perhaps damped ring 7 is undulating springs sheet circles, and it is anti-rotten, ageing resistance is better.
Claims (2)
1, damped type diaphragm coupling, comprise half-coupling (1,2), jack shaft (3) and diaphragm (4,5), diaphragm (4,5) is integrated type diaphragm or linkage type diaphragm, it is characterized in that, between jack shaft (3) and two half-couplings (1,2), be provided with land (6), land (6) and half-coupling (1,2) are that one constitutes or fixedlys connected by bolt (8), and land (6) inner ring surface is provided with damped ring (7), and jack shaft (3) cooperates with damped ring (7).
2, damped type diaphragm coupling according to claim 1 is characterized in that, damped ring (7) is rubber ring, nylon ring, or undulating springs sheet circle.
