Description
Horeuvedené nedostatky odstránuje pneumatická pružná hriadelová spojka s plynule měnitelnou charakteristikou a tlmením torzných kmitov a torzných nárazov, zaradená medzi hnacou a poháňanou časťou sústroja, skladajúoa sa z 1’avej a právej príruby, z l'avého a pravého kotúča a medzi nimi umiestnenýai vakom naplněným plynom.The above-mentioned drawbacks are eliminated by a pneumatic flexible shaft coupling with continuously variable characteristic and damping of torsional oscillations and torsional impacts, placed between the driving and driven parts of the kit, consisting of 1-left and right flanges, left and right discs and fully placed gas.
Medzi přírubami a kotúčmi sú ozuby umožnujúce posunutie kotúčov smerom k pružnému vaku. Kotúče majú vybrania na obvode opatřené žliabkami, do ktorých zapadajú zuby náboja. Spojka sa vyznačuje tým, že pružný vak je vo vnútri delený najmenej jednou dierovanou membránou a je napojený na reduktor s přídavným plynule měnitelným objemom.Between flanges and discs there are teeth allowing the discs to move towards the flexible bag. The discs have recesses on the periphery provided with grooves in which the teeth of the hub engage. The coupling is characterized in that the flexible bag is internally divided by at least one perforated membrane and is connected to a reducer with an additional continuously variable volume.
Zariadenie je bližšie vysvětlené na priloženom vyobrazení, ktoré představuje pneumatická pružná hriadelovú spojku s plynule měnitelnou charakteristikou a tlmením torzných kmitov a torzných nárazov, s pružným vakom vo vnútri deleným dierovanou membránou1, ktorý je napojený na reduktor s přídavným plynule měnitelným objemom.The device is explained in more detail in the accompanying drawing, which represents a pneumatic flexible shaft coupling with continuously variable characteristic and damping of torsional oscillations and torsional impacts, with a flexible bag inside divided by a perforated diaphragm 1 , which is connected to a reducer with additional continuously variable volume.
Spojka podlá vynálezu spája hnací hriadel J. a poháňaný hriadel’ 2 cez perá 2 ’ ίθ pomocou hnacieho náboja J a poháňaného náboja £. Tieto náboje J a ktoré nesú bombírované zuby, zapadajú do kotúča 5 a 6 so svojimi žliabkami. Pravý kotúč 6 je s pravou přírubou 8 a lavý kotúč j, je s 1’avou přírubou 2 spojený ozubmi.The clutch according to the invention connects the drive shaft J and the driven shaft 2 through the tongues 2 by means of the drive hub J and the driven hub 6. These cartridges J, which carry the pickled teeth, fit into the discs 5 and 6 with their grooves. The right wheel 6 is with the right flange 8 and the left wheel 6 is connected with the teeth 1 'to the left flange 2.
Pružný vak sa skládá z právej časti 12 a 1’avej časti 11. vo vnútri delený dierovanou membránou 14. na ktorý je přívodovým potrubím 21 napojený reduktor skladajúci sa z valca 16. veka 18. membrány 17 a hrdiel 15 a 20.The resilient bag consists of the right portions 12 and 1 'and the left portion 11 internally divided by a perforated diaphragm 14 to which a reducer consisting of a cylinder 16 of the lid 18 of the diaphragm 17 and the necks 15 and 20 is connected via a supply line 21.
Ak pružný vak nahustíme plynným médiom napr. vzduchom a spojku zaťažíme krútiacim momentom, 1’avý kotúč 2 v ozube príruby 2, ktorý je skrutkovite usporiadaný sa axiálně posunie smerom k vaku. Reakcia krútiaceho momentu na právej straně spojky má za následok, že pravý kotúč 6 v ozube príruby 8, ktorý je tiež skrutkovite usporiadaný, ale s opačným stúpaním, sa axiálně posunie smerom k vaku. Toto posunutie je fázovo posunuté proti akčnému momentu krútiacemu.If the flexible bag is inflated with gaseous medium eg. the air and the coupling are loaded with a torque, the left-hand disk 2 in the flange 2 of the flange 2, which is helically arranged, is axially displaced towards the bag. The torque reaction on the right side of the coupling results in the right disc 6 in the flange 8 of the flange 8, which is also helically arranged but with the opposite incline, axially displaced towards the bag. This displacement is phase shifted against the torque action moment.
Fázový posuv medzi akciou a reakciou mé za následok premiestňovanie časti plynného média dierovanou membránou 1 4. V ddsledku škrtenia pri prietoku plynného média v otvoroch membrány nastáva strata kmitajúoej energie prenéšané spojkou. Táto strata. je priamoúmerné tlmiaoej práci spojky, ktorá sa mění v teplo a je kovovými časťami spojky odvádzaná do okolitej atmosféry.The phase shift between the action and the reaction results in the displacement of a portion of the gaseous medium through the perforated membrane 14. As a result of throttling as the gaseous medium flows through the diaphragm openings, there is a loss of oscillating energy transmitted by the coupling. This loss. is proportional to the damping work of the coupling, which turns into heat and is discharged through the metal parts of the coupling into the ambient atmosphere.
Ak reduktor naplníme kvapalinou, potom komprimujeme len objem plynu nachádzajúci sa vo vaku. Pri vyprázdnění reduktora od kvapaliny a naplněni tohoto priestoru plynom cez hrdlo 20 na pdvodný tlak aký je vo vaku, potom komprimujeme objem plynu vo vaku a v reduktoru.If the reducer is filled with liquid, then only compress the volume of gas contained in the bag. By emptying the reducer from the liquid and filling the space with gas through the throat 20 to the original pressure as in the bag, then compress the volume of gas in the bag and in the reducer.
Tak charakteristika spojky představované polytropiokou stavovou změnou plynu pre objem vaku je iná ako pre súčet objemov vaku a reduktora. Tak dostáváme sústavu kriviek charakteristik plynule měnitelných v spomínaných rozsahoch objemov, ktoré pre ten istý nominálny krútí.raoi moment predstavujú rflznu tuhosť spojky. Tým spojka sa stává plynulým ladičom torznej sústavy s plynule měnitelnou torznou tuhosťou a tlmením torzných kmitov a torzných nárazov.Thus, the characteristic of the coupling represented by the polythropic state gas change for the bag volume is different from the sum of the bag and reducer volumes. Thus we obtain a set of curve curves that are continuously variable in the mentioned ranges of volumes, which for the same nominal twist. Thus, the clutch becomes a continuous torsion tuner with continuously variable torsional stiffness and damping of torsional oscillations and torsional impacts.
Přenos mechanickej energie pneumatickou pružnou hriadelovou spojkou podlá vynálezu eliminuje nevýhody doteraz používaných pružných spojok a dává tieto na kvalitativně vyššiu úroveň.The transfer of mechanical energy by the pneumatic flexible shaft clutch according to the invention eliminates the disadvantages of the flexible clutches used hitherto and brings these to a qualitatively higher level.
Spojka podlá vynálezu mé plynule měnitelná křivková charakteristiku přenosu krútiaceho momentu s tlmením torzných kmitov a torzných nárazov.The coupling according to the invention has a continuously variable torque transmission curve with torsional vibration damping and torsional shock absorption.
Spojka nepodlieha únavě alebo stárnutiu pružného člena. Životnost spojky je limitovaná životnosťou kovových častí. Je torzné velmi makké, umožnujúca axiálně, radiálně a úhlové odchylky osí zviazaných strojov. Pre jeden směr otáčania je pružnou a poistnou spojkou pre druhý pevnou zubovou dilatačnou spojkou.The coupling is not subject to fatigue or aging of the resilient member. The service life of the coupling is limited by the service life of the metal parts. It is torsion very soft, allowing axial, radial and angular deviations of axes of bound machines. For one direction of rotation it is a flexible and safety clutch for the other a fixed tooth expansion joint.
Vzhl’adom na to, že spojka podTa vynálezu je plynulým ladičom torznej sústavy počas jej prevádzky, i pri plnom zatažení nájde uplatnenie všade tam, kde sa chceme vyhnút rezonančným (kritickým) stavom sústavy pri přenose mechaniokej energie a so všetkou díslednosťou vysporiadať s nežiaduoim torzným kmitáním a torznými rázmi.Since the clutch according to the invention is a continuous torsion tuner during its operation, even under full load, it will find its application wherever we want to avoid the resonant (critical) state of the system when transmitting mechanical energy and deal with unwanted torsion with all due diligence. vibrations and torsional shocks.
Tým zvýšíme životnost a prevádzkovú spoTahlivosť celého sústroja, v ktorom je spojka zaradená. Hlavně sa mdže použit při kompletáži piestovýoh motorov od středných až po najvačšie přenášené výkony a to při stavbě hnacieho sústroja lodí, dieselových a dieselo-elektrických lokomotiv, kompresorov, válcovacích stolíc, kde k mechanickým namáhaniam pribúdajú i tepelné a pod.This will increase the service life and operational reliability of the entire unit in which the clutch is engaged. Mainly it can be used in assembling piston engines from medium to the highest transmitted power, and in the construction of drivetrain ships, diesel and diesel-electric locomotives, compressors, rolling stands, where the mechanical stresses are increasing and thermal and so on.
