It consists of the coating (1), in which the guide rod (3) is located, while the guide rod (3) is equipped with the direct grooving (5) and close-connected with the flange (8), which closes the coating (1) of the hydraulic motor from one side. The piston (2) is moveably mounted on the direct grooving (5) of the guide rod (3). The bolt grooves (19) are arranged on the extended part (6) of the piston (2). The projections (7), which are created on the bush (4), fit into the bolt grooves (19), while the bush (4) is hinged in the coating (1) of the hydraulic motor and close-connected with the lid (9), which is hinged on the free end of the guide rod (3) and which closes the coating (1) of the hydraulic motor from the other side.<IMAGE>

Description

Vynález sa týká kývavého hydromotora.The invention relates to a swinging hydraulic motor.

Známe riešenía meniace priamočiary pohyb piestu na rotačný sú charakteristické rozmernosťou, zložitosťou, malým měrným výkonom, uhlom natáčania menším ako 360°. Riešenxe, při kotorom ozubené kolo zaberá do ozubenej piestnice vloženej medzi dva jednočinné priamočiare hydromotory sa vyznačuje velkým rozmerom a nutnosťou zachytit silu, ktorá vytláča ozubená piestnicu z ozubenía, a tým vačšou zložitosťou. Xné ríešenie je také, kde súčasťou piesta je dvojstranná drážkovaná piestnica, z ktorých jedno drážkovanie je skrutkové. Drážkované púzdra, ktoré zapadajú do drážkovaní piestnice sú zabudované do viek válce, z ktorých jedno púzdro je otočné uložené vo veku válce. Dlžka takéhoto usporiadania je trojnásobkom dlžky zdvihu piesta, přitom měrné tlaky na drážkovaní piestnice sú vysoké, zariadenie je zložité. Balšie riešenie je také, kde sa nahradí priame drážkovanie piestnice vodiacou týčou, umiestnenou do činného priestoru priamočiareho hydromotora, tým sa zvačšuje priemer priamočiareho hydromotora a toto riešenie naviac nedosiahne, ani nemčže byť zatažené vyšším krútiacim momentom.Known solutions that change the linear movement of the piston into a rotary piston are characterized by size, complexity, low specific power, and a pivot angle of less than 360 °. The solution, in the case of a rotor, engages a gear piston rod inserted between two single-acting rectilinear hydraulic motors, characterized by a large size and the necessity to absorb the force that forces the gear piston rod out of the gear and hence greater complexity. The solution is one where the piston has a double-sided grooved piston, one of which is a helical groove. The grooved bushes that fit into the piston rod grooves are built into the cylinder lids, one of which is rotatably mounted in the cylinder lid. The length of such an arrangement is three times the length of the piston stroke, while the specific pressures on the grooving of the piston rod are high, the device is complex. The baler solution is one in which the direct grooving of the piston rod is replaced by a guide rod placed in the working space of the linear hydraulic motor, thereby increasing the diameter of the linear hydraulic motor, and this solution does not reach or even be subject to higher torque.

Uvedené nevýhody odstraňuje kývavý hydromotor pozostávajúci z plášťa, v ktorom je umiestnená vodiaca tyč opatřená priamym drážkováním a pevne spojená s přírubou uzatvárajúcou z jednej strany plášť hydromotora, pričom na priamom drážkovaní vodiacej tyče je posuvné uložený piest podlá vynálezu, ktorého podstata spočívá v tom, že na predíženej časti piesta je vytvořené Skrutkové drážkovanie a na púzdre výstupky skrutkového drážkovania púzdra otočné uloženého v plášti hydromotora a pevne spojeného s vekom, ktoré je otočné uložené na volnom konci vodiacej tyče a ktoré uzatvára plášť hydromotora z druhej strany.These drawbacks are overcome by a swinging hydraulic motor consisting of a housing in which a guide rod provided with a direct grooving is placed and firmly connected to a flange closing on one side of the housing of the hydraulic motor, the piston according to the invention being displaceable on the direct grooving of the guide rod. a screw groove is provided on the extended part of the piston; and on the housing, the lugs of the screw groove of the sleeve rotatably mounted in the housing of the hydraulic motor and fixedly connected to the lid are rotatably mounted on the free end of the guide rod.

Výhodou kývavého hydromotora podlá vynálezu je najma jeho jednoduchá konštrukcia umožnujúca dokonalé využitie činného priestoru hydromotora pri výraznom znížení měrných tlakov na jeho funkčných častiach, čo dovoluje dosiahnuť vyššie krútiace momenty. Výhodou sú tiež malé rozměry hydromotora.The advantage of the swinging hydraulic motor according to the invention is, in particular, its simple construction, which makes it possible to make perfect use of the working space of the hydraulic motor while significantly reducing the specific pressures on its functional parts, which allows to achieve higher torques. The small dimensions of the hydraulic motor are also an advantage.

Na pripojenom výkrese je znázorněný příklad vytvorenia kývavého hydromotora v pozdXžnom řeze.The attached drawing shows an example of a longitudinal section of a rocking hydraulic motor.

Kývavý hydromotor pozostáva z plášťa 1, v ktorom je umiestnená vodiaca tyč 3 opatřená priamym drážkováním £5 ukončená přírubou 8 uzatvárajúcou plášť .1 hydromotora z jednej strany. Na priamom drážkovaní 5 vodiacej tyče 3 je posuvné uložený piest 2, ktorý má na svojej predíženej časti 6 vytvořené skrutkové drážky 11. Na púzdre 4 otočné uloženom v plášti I. hydromotora sú vytvořené výstupky 7 skrutkového drážkovania. Púzdro 4 je pevne spojené s vekom 9_r ktoré je otočné uložené na volnom konci vodiacej tyče 3 a ktoré uzatvára plášť JL hydromotora z druhej strany.The oscillating hydraulic motor consists of a housing 1 in which a guide rod 3 provided with a direct grooving 5 is provided, terminated by a flange 8 closing the housing 11 of the hydraulic motor from one side. The piston 2 is displaceably mounted on the direct groove 5 of the guide rod 3, which has screw grooves 11 formed on its extended part 6. Case 4 is fixed to the lid 9 is R which is rotatably mounted at the free end of the bar 3 and which closes the housing of the hydraulic motor JL on the other side.

Počas prevádzky sa pracovná kvapalina privádza napr. prvým otvorom 12 do prvého pracovného priestoru A a cez medzeru v drážkovaní do priestoru E3. Posobením tlaku pracovnej kvapalxny sa piest 2 začne pohybovat smerom hoře, pričom priamočiary pohyb piesta 2 sa na skrutkových drážkách 11 do ktorých zapadajú výstupky 7 mění na rotačný pohyb púzdra 4 a teda aj veka 9, s ktorým je púzdro 4 pevne spojené. Ak privádzame pracovnú kvapalinu druhým otvorom 13 do tretieho pracovného priestoru C a medzerami v skrutkových drážkách 11 tiež do štvrtého pracovného priestoru D, pohybuje sa piest 2 smerom dolu a púzdro 4 s vekom 9 sa otáča v opačnom smere.During operation, the working fluid is supplied e.g. through a first opening 12 into the first working space A and through a gap in the grooving into the space E3. By applying the pressure of the working liquid, the piston 2 begins to move upwardly, the linear movement of the piston 2 on the screw grooves 11 into which the projections 7 fit into the rotational movement of the housing 4 and hence of the lid 9 with which the housing 4 is firmly connected. If the working fluid is supplied through the second opening 13 to the third working space C and by the gaps in the screw grooves 11 also to the fourth working space D, the piston 2 moves downwards and the housing 4 with the lid 9 rotates in the opposite direction.

Kývavý hydromotor sa s výhodou uplatní všade tam, kde sa vyžaduje otáčavý vratný pohyb vačších hmot, resp. vyvodzovanie vačších krútiacich momentov, ako napr. v banských, stavebných a zemných pracovných zariadeniach.The oscillating hydraulic motor is advantageously used wherever a rotary reciprocating movement of larger masses, respectively, is required. deriving greater torques, such as in mining, construction and earthwork equipment.
