Abstract
The present invention relates to a shaft coupler. The present invention is suitable for occasions of transferring the torque or the movement (the transferred movement is spiral movement or rotary movement) of a rotating part to another rotating part, particularly for occasions of transferring the torque and the forward and reverse spiral movement of a spiral hydraulic motor to a fly wheel by a hydraulic screw press. The present invention is composed of two half shaft couplings, a shaft coupler outer ring and a fan-shaped block, wherein the fan-shaped block is embedded between a tenon of the two half shaft coupling and an outer ring of the shaft coupler.
Description
The present invention relates to a kind of coupling, it is applicable to gives another rotor the moment of torsion of a rotating component and transmission of movement, and the motion of being transmitted is to rotatablely move or the occasion of spiral motion.Be specially adapted to the moment of torsion of spiral oil hydraulic motor and the occasion that forward and reverse spiral motion passes to flywheel.
Prior art is the normal sliding cross coupling that adopts in mechanical transmission, sliding cross coupling shown in Machine Design book series " coupling " chapter 3 first segment (the 31st page), it has mutually the intermediate slider of vertical tenon and forms with one with the half-coupling of groove radially by two, this rigid coupling is because when transmitting torque, the tenon of intermediate slider bears big moment of flexure and causes half-coupling and the essential higher metallic material of intensity that adopts of intermediate slider, and its poor impact resistance, easy to wear.In the flywheel motion of hydraulic screw press drove, coupling was wanted transmitting large torque, needed frequent clockwise and anticlockwise, frequent starting, and withstanding shocks property varying load, and live axle and flywheel shaft all have big displacement radial and axial.At this moment, above-mentioned cross coupler just can not adapt to.
Chinese patent No.92216086.4 disclosed " extruding type elastic coupling flexible coupling ", driven wheel is respectively inside and outside cross, accompanies 8 columniform rubber rods between the two.The deficiency of this structure is, only allowing has a small amount of off-centre between live axle and the driven shaft, centring error can be remedied by the flattening deformation of rubber rod, when off-centre is big slightly, need are more flat the rubber rod pressure, so produce bigger, periodically variable additional radial pressure on live axle and driven shaft.Simultaneously, when causing rubber rod to flatten owing to off-centre, contiguous rubber rod then is in gapped loosening state, the impact in the time of can causing the live axle counterrotating.
Chinese patent No.92113751.6 disclosed " coupling " can adapt to the centring error between live axle and the driven shaft, the cylindrical body end face of its half-coupling is provided with symmetrical tenon, torque driving component with the plastics manufacturing is installed between two half-couplings, this plastics torque driving component is formed with the disk of spin axis right angle intersection, an interior annulus, an outer toroid and 8 gussets by one, as a whole inside and outside annulus connection by 8 gussets, gusset and interior annulus are contour.From the technology of this patent disclosure as seen, the structure of its torque driving component is comparatively complicated, and when being used on the hydraulic screw press transmitting torque, its profile is bigger, and making inner chamber, to contain the expense of the big mould of torque driving component and plastics forming machinery very high.In addition, because suffered pulling force, extruding force, bending force or the composite force in each position of this driving component is all different or changing at any time, and the rib that working of plastics constitutes is thiner, so working of plastics inside local defect might develop into destructive defective.Therefore, the coupling that above-mentioned prior art is involved, the use occasion of very unsuitable hydraulic screw press.
At the shortcoming that above-mentioned prior art exists, task of the present invention provides a kind of coupling that is used in hydraulic screw press.
The present invention implements by following technical measures: it is a kind of two half-couplings 4 that pass through, 6, coupling outer shroud 1 and sector unit 5 constitute the also coupling of transmitting torque, described half- coupling 4,6 respectively have the radially tenon of symmetry, described sector unit 5 is entrenched in two half-couplings 4, between 6 tenon and the coupling outer shroud 1, its material is for adopting little padded coaming such as the nylon of Young's modulus, engineering plastics, cloth matter phenolic laminated sheet and rubber etc., the number of the number of sector unit 5 and two half-coupling tenons is determined by designing and calculating, described coupling outer shroud 1 connects with blind flange 2, and outer shroud 1 floats with flywheel shaft 7 by pad 8 and connects.Half-coupling 4 is fastened on the axle head of coupled running shaft 3, and half-coupling 6 is fastened on the coupled flywheel shaft 7.Coupling outer shroud 1 can curl wire rope or nylon rope or adopt spring structure for having the thin walled structures that sufficient intensity has favorable elasticity again at its outer wall.9 is the fastener of half-coupling 4 and axle 3.
Described sector unit 5 is symmetrical distribution, and at the coupling outer shroud 1 inner cross chute that forms, the tenon of two half- couplings 4,6 is arranged in the cross chute.
In coupling outer shroud 1, the structural approach that is combined to form the cross chute by sector unit 5 makes the axle head of running shaft 3 and the inside that half-coupling 4 can all extend into coupling outer shroud 1, sector unit 5 has not taken axial dimension again separately, thereby the axial dimension of coupling is little, when being used on the hydraulic screw press, less to the height increasing amount of press machine.
Advantage of the present invention: (one) is simple in structure, and is easy to manufacture, easy installation and removal, and transmitting torque is big.(2) allow the diaxon malalignment to have than mistake.(3) allow diaxon that big alignment error is axially arranged.Larger axis is arranged to string quantity of motion when (four) allowing two shaft drive.(5) allow diaxon that certain parallel error is arranged.(6) good springiness can relax impact.(7) additional radial pressure is little, and additional axial force is little, long service life.(8) be specially adapted to high-power, frequent forward and backward, starting is frequent, impact force is big, diaxon is in the radial and axial occasion that big displacement is arranged.(9) axial dimension is little, compact structure.
