Abstract

A high-strength flexible coupling comprises a first half coupling, a second half coupling, a rotating shaft and a rubber ring. The first half coupling is connected with one end of the rotating shaft through a first bearing. The second half coupling is connected with the other end of the rotating shaft through a second bearing. A first step ring is arranged outside the rotating shaft in a sleeving manner. A second step ring is arranged outside the first step ring in a sleeving manner. The rubber ring is arranged outside the rotating shaft, the first step ring and the second step ring. Deformation buffering is conducted on the thinnest part when the twisting force is small. Deformation buffering is conducted on the thick part when the twisting force is increased. Deformation buffering is conducted on the thickest part when the twisting force is very large. In addition, due to the fixing effect of the rotating shaft, the phenomena of displacement and dislocation cannot happen to the rubber ring, the service life is ensured, and a protection shell is arranged outside the first half coupling and the second half coupling.

Description

A kind of high-strength flexible shaft coupling
Technical field
The present invention relates to a kind of hoisting machinery, especially a kind of high-strength flexible shaft coupling.
Background technology
Shaft coupling is parts conventional in machine driving, is mainly used to the intermediate transmission mechanism of coupling spindle and axle or coupling spindle and other pivoting part, with transmitting movement and torque.Some equipment can produce bigger impulsive force when transmitting torque at present, and therefore this kind equipment generally uses balata belt to transmit torque as shaft coupling, but this type of Coupling Life is short, maintenance frequent, it is impossible to meet the transmission requirement that impulsive force is bigger.
Improved in the industry, such as Chinese patent discloses a kind of flexible clutch, application number: 201310230404.5, the applying date: 2013-06-12, a kind of flexible clutch, including the first half a coupler and the second half a coupler, it is provided with connection dish, described first half a coupler and the second half a coupler between described first half a coupler and the second half a coupler and is connected by least three steel wire rope with being connected between dish.Beneficial effect: the present invention arranges the connection dish being connected with steel wire rope between the first half a coupler and the second half a coupler, thus wirerope-winding affects the shortcoming of transmission when shaft coupling can be avoided to rotate, present configuration is simple simultaneously, length in service life, can bear the moment of torsion of greater impact.
The deficiency of this technical scheme is: 1) connected by steel wire rope, lacks rigidity of fixation, easily misplaces;2) the easy article with miscellaneous part or the external world of steel wire rope tangle;3) two half a couplers can be produced bigger axial tension when several steel wire ropes rotate, service life shortens.
Summary of the invention
For the deficiencies in the prior art, the present invention provides a kind of and does not haves the flexible clutch that dislocation will not interfere with miscellaneous part and axial tension is less.
The technical scheme is that
A kind of high-strength flexible shaft coupling, including the first half a coupler, second half a coupler, rotating shaft, rubber ring, it is characterized in that: the first described half a coupler and the second half a coupler are that minute surface is arranged, its benefit is two half a couplers all has identical character axially and transversely going up, it is in operation and will not produce unnecessary torsion and burden, the first described half a coupler, second half a coupler is connected by rotating shaft, the first described half a coupler is the other end by the second bearing connection rotating shaft by clutch shaft bearing connection rotating shaft wherein one end and the second half a coupler, it is spacing that its effect is so that whole device has been carried out on axially and transversely, make two and half shaft couplings and miscellaneous part be only capable of rotation to move to other directions, effectively prevent the dislocation of parts;
nullDescribed rotating shaft outer sheath is provided with length less than the first step ring of minimum range between the first half a coupler and the second half a coupler,Described first step ring outer sheath is provided with the length second step ring less than first step ring,Described rotating shaft、The outside of first step ring and second step ring is provided with internal diameter and closely cooperates rotating shaft、First step ring and the rubber ring of second step ring outer peripheral face,Described rubber ring two ends are also uniformly provided with some embedding teeth,The described tooth that embeds embeds the first half a coupler corresponding to rubber ring two ends end face and the second half a coupler end face,Its effect is to accept the torsion between two half a couplers by having the rubber ring of step-thickness,The part the thinnest when torsion is less carries out deformation buffering,The part thicker when torsion increases carries out deformation buffering,The part the thickest when torsion is the biggest carries out deformation buffering,Fixation additionally, due to rotating shaft makes rubber ring not have the phenomenon of displacement dislocation,Service life is protected;
The first described half a coupler and the outside of the second half a coupler are provided with containment vessel; described containment vessel is minor diameter fit the first half a coupler, the ring bodies of the second half a coupler external diameter; being provided with ball between described containment vessel inner peripheral surface and the first half a coupler, the second half a coupler outer peripheral face and coordinate the round and smooth groove of ball, its effect is to utilize containment vessel protection interior arrangement do not interfered by external items and have dustproof effect.
Further, described rotating shaft, the junction embedding tooth and containment vessel and the first half a coupler, the second half a coupler of rubber ring are equipped with axial fixing mechanism, and its effect is to avoid above-mentioned parts to occur axial displacement to cause device to fall apart.
Further, described rotating shaft, first step ring, second step ring use one-body molded making, and its effect is to avoid rotating shaft, first step ring, second step ring to cause device to damage because assembling is improper.
Further, described containment vessel two ends are provided with sealing ring, are marked with fire resistant fluid in the space between described containment vessel and rubber ring, and described containment vessel outer wall is provided with some fin, and its effect is the rubber ring preventing frequent deformation because high temperature burns.
Further, the material of described rubber ring is high-strength abrasion-proof stretch-proof rubber, and its effect is to improve overall durability degree further by the intensity improving rubber ring.
The invention have the benefit that present configuration is simple, by having the rubber ring of step-thickness distribution, torsion in section is buffered, flexibility and the intensity of device are well equalized, additionally by the effect of rotating shaft and two bearings makes rubber ring be only capable of rotating along with half a coupler, transverse shifting can not occur, it is to avoid many degree deformation and will not interfering with miscellaneous part or extraneous things.
