Description

Oblasť technikyTechnical field

Vynález sa týka ložiska s plastovou segmentovou klietkou, najmä veľkorozmerového radiálneho kuželíkového ložiska, vhodného na uloženie rotora veternej elektrárne.The invention relates to a bearing with a plastic segment cage, in particular to a large-dimension radial tapered roller bearing suitable for receiving a rotor of a wind power plant.

Doterajší stav technikyBACKGROUND OF THE INVENTION

V záujme zníženia nákladov a zjednodušenia výroby ložiskových klietok pre veľkorozmerové valivé ložiská, s priemerom nad 1000 mm, sa ložiskové klietky vyrábajú z plastových segmentov. Tieto segmenty sú vyrábané alebo vo forme samostatných, navzájom nespojených rozperných prvkov oddeľujúcich jednotlivé valivé telieska v ložisku, alebo vo forme boxov, v ktorých sú vytvorené kapsy na uloženie jedného alebo viac valivých teliesok. Kapsy sú ohraničené vnútornými plochami bočníc segmentu a priečkami spájajúcimi bočnice segmentu. Z hľadiska umožnenia montáže kompletného ložiska, musia byť valivé telieska v segmentoch boxového typu zabezpečené proti vypadnutiu z kapsy.In order to reduce costs and simplify the production of bearing cages for large-size rolling bearings with a diameter above 1000 mm, the bearing cages are made of plastic segments. These segments are manufactured or in the form of separate, non-interconnected spacing elements separating the individual rolling elements in the bearing, or in the form of boxes in which pockets are formed to receive one or more rolling elements. The pockets are delimited by the inner surfaces of the sidewalls of the segment and the partitions connecting the sidewalls of the segment. In order to enable the assembly of the complete bearing, the rolling elements in the box-type segments must be secured against falling out of the pocket.

Riešenie kuželíkového ložiska s plastovou segmentovou ložiskovou klietkou boxového typu je známe z patentového spisu WO 2006/094661. Obvodové vedenie valivých teliesok v kapsách je v tomto riešení zabezpečené valcovými plochami vytvorenými na susediacich priečkach. Aby valivé telieska z kapsy nevypadli, je vzdialenosť hrán protiľahlých valcových plôch káps menšia, ako je priemer valivého telieska. Do kapsy sa telieska vkladajú postupne tak, že sa teliesko položí na vstupný otvor kapsy a pôsobí sa naň tlakom, čím sa v medziach pružnej deformácie od seba oddialia hrany protiľahlých valcových plôch kapsy a teliesko vnikne do kapsy. Následne sa hrany protiľahlých valcových plôch kapsy vrátia do pôvodnej polohy, v dôsledku čoho je valivé teliesko zabezpečené proti vypadnutiu.A tapered roller bearing solution with a box segment plastic bearing cage is known from WO 2006/094661. In this solution, the circumferential guidance of the rolling elements in the pockets is provided by cylindrical surfaces formed on adjacent partitions. In order to prevent the rolling elements from falling out of the pocket, the edge distance of the opposing cylindrical surfaces of the caps is smaller than the diameter of the rolling element. The bodies are inserted sequentially by placing the body on the inlet opening of the pocket and applying pressure thereto, so that within the limits of elastic deformation the edges of the opposing cylindrical surfaces of the pocket are separated and the body enters the pocket. Subsequently, the edges of the opposing cylindrical surfaces of the pocket return to their original position, as a result of which the rolling element is secured against falling out.

Nevýhody známeho stavu techniky sú v tom, že na zatlačenie telieska do kapsy je potrebné vyvinúť značnú tlakovú silu, nakoľko styková plocha hrán protiľahlých valcových plôch kapsy s obvodovou plochou valivého telieska je veľká a pri prevádzke ložiska môže dochádzať k odieraniu hrán, čo môže byť dôvodom na vypadávanie teliesok z kapsy pri neskoršej demontáži ložiska. Nevýhodou známeho stavu techniky tiež je, že segment klietky musí byť vyrobený s vysokou presnosťou. Pri nedodržaní presnosti rozmerov segmentu hrozí nebezpečenstvo, že teliesko sa do kapsy nebude dať zasunúť alebo bude z nej vypadávať.The disadvantages of the prior art are that a considerable pressure force is required to push the body into the pocket, as the contact surface of the opposing cylindrical surfaces of the pocket with the peripheral surface of the rolling body is large and the edges may scuff when operating the bearing. for dropping bodies from the pocket when the bearing is later removed. A disadvantage of the prior art is also that the cage segment must be manufactured with high precision. Failure to observe the accuracy of the segment dimensions may result in the body not being able to be inserted or dropped into the pocket.

Podstata vynálezuSUMMARY OF THE INVENTION

Uvedené nedostatky do značnej miery odstraňuje ložisko s plastovou segmentovou klietkou, ktorej segmenty sú tvorené bočnicami, prepojenými najmenej dvomi priečkami tak, že medzi priečkami sú vytvorené kapsy na uloženie valivých teliesok, podľa tohoto vynálezu, ktorého podstata spočíva v tom, že v každej kapse je na vnútornej ploche aspoň jednej bočnice vytvorený záchyt, pričom radiálne je záchyt umiestnený mimo stred výšky bočnice a tangenciálne v strede medzi bočnými stenami susediacich priečok. Takéto riešenie umožňuje bezpečné uloženie valivého telieska do kapsy ložiskovej klietky, odolné proti vypadnutiu ložiskového telieska z kapsy pri montáži ložiska. Tlaková sila, potrebná na zasunutie valivého telieska do kapsy ložiskovej klietky je minimálna, nakoľko styková plocha záchytu s čelnou plochou valivého telieska je veľmi malá. Pritom sa podstatne znižujú nároky na presnosť rozmerov segmentu a zvyšuje sa variabilita konštrukcie segmentu.These drawbacks are largely eliminated by a bearing with a plastic segment cage, the segments of which are formed by sidewalls interconnected by at least two partitions, so that pockets for the rolling elements according to the invention are formed between the partitions. a catch formed on the inner surface of the at least one sidewall, wherein the catch radially is located off the center of the sidewall height and tangentially in the middle between the side walls of adjacent crossbars. Such a solution allows a secure fit of the rolling element in the pocket of the bearing cage, resistant to dropping of the bearing element from the pocket when mounting the bearing. The pressure force required to insert the roller into the pocket of the bearing cage is minimal since the engagement surface of the catch with the front surface of the roller is very small. At the same time, the demands on the accuracy of the segment dimensions are substantially reduced and the variability of the segment construction is increased.

Ďalej podstata vynálezu spočíva v tom, že záchyt má tvar výstupku, vytvoreného na bočnici priliehajúcej k funkčnému čelu valivého telieska, pričom vzdialenosť medzi vrcholom záchytu a vnútornou plochou protiľahlej bočnice je menšia ako dĺžka valivého telieska. Takéto riešenie umožňuje výhodne využiť technologický otvor vytvorený na funkčnom čele valivého telieska na zapadnutie záchytu v tvare výstupku.It is a further object of the present invention to provide the catch in the form of a projection formed on a sidewall adjacent to the functional face of the rolling element, the distance between the top of the catch and the inner surface of the opposite sidewall being less than the length of the rolling element. Such a solution makes it possible advantageously to utilize a technological opening formed on the functional face of the rolling element to engage the projection-shaped catch.

Ďalej podstata vynálezu spočíva vtom, že výška priečok je menšia ako výška bočníc, čo umožňuje podstatne zmenšiť hrúbku priečok, ktoré v menšej miere zaberajú miesto v priestore určenom pre valivé telieska. Ložisko môže byť teda vybavené optimálnym počtom valivých teliesok čo má priaznivý vplyv na zvyšovanie únosnosti ložiska.A further object of the invention is that the height of the crossbars is smaller than the height of the sidewalls, which makes it possible to substantially reduce the thickness of the crossbars which occupy less space in the space intended for rolling elements. Thus, the bearing can be provided with an optimum number of rolling elements, which has a beneficial effect on increasing bearing capacity.

Podstata vynálezu spočíva tiež v tom, že polomer zakrivenia bočných stien priečky je väčší ako polomer obvodovej plochy valivého telieska, čím sa dosiahne priamkový styk obvodovej plochy valivých teliesok s bočnými stenami priečky, čo má priaznivý vplyv na mazacie pomery v ložisku.It is also an object of the invention that the radius of curvature of the lateral walls of the crossbar is greater than the radius of the circumferential surface of the rolling element, thereby achieving a linear contact of the circumferential surface of the rolling elements with the lateral walls of the crossbar.

Nakoniec podstata vynálezu spočíva v tom, že susediace segmenty sa navzájom dotýkajú svojimi čelnými plochami, čo má priaznivý vplyv na stabilné uloženie segmentov klietky v ložisku bez toho, aby bolo potrebné konce segmentov vybavovať prvkami na vzájomné spojenie segmentov.Finally, the subject matter of the invention is that adjacent segments contact each other with their end faces, which has a beneficial effect on the stable fit of the cage segments in the bearing without the need to equip the ends of the segments with elements for interconnecting the segments.

Príklad uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION

Valivé ložisko znázornené na obr. 1 je tvorené vonkajším krúžkom 1 a vnútorným krúžkom 5, medzi ktorými sú usporiadané valivé telieska 3, uložené v klietke znázornenej na obr. 2 zloženej zo siedmich segmentov 2. Ako z obrázkov vidieť, susediace segmenty 2 sa navzájom dotýkajú svojimi čelnými plochami 213.The rolling bearing shown in FIG. 1 is formed by an outer ring 1 and an inner ring 5, between which rolling elements 3 are arranged, housed in the cage shown in FIG. 2, composed of seven segments 2. As can be seen from the figures, adjacent segments 2 contact each other with their end faces 213.

Segment 2 znázornený na obr. 3 a obr. 4 je tvorený bočnicami 21. prepojenými šiestimi priečkami 22. tak, že medzi priečkami 22 je vytvorených päť káps 24 na uloženie valivých teliesok 3. V každej kapse 24 je na vnútornej ploche 211 jednej bočnice 21 vytvorený záchyt 23 v tvare výstupku. Záchyt 23 je umiestnený radiálne mimo stred výšky bočnice 21 a tangenciálne v strede medzi bočnými stenami 221 susediacich priečok 22. Vzdialenosť medzi vrcholom záchytu 23 a vnútornou plochou 211 protiľahlej bočnice 21 je menšia ako dĺžka valivého telieskaThe segment 2 shown in FIG. 3 and FIG. 4 is formed by side walls 21 interconnected by six partitions 22, so that five pockets 24 are provided between the partitions 22 for receiving rolling elements 3. In each pocket 24, a projection 23 is formed on the inner surface 211 of one side 21. The retainer 23 is located radially off center of the height of the sidewall 21 and tangentially in the middle between the side walls 221 of adjacent crossbars 22. The distance between the top of the catch 23 and the inner surface 211 of the opposite side 21 is less than the length of the roller

3. Valivé teliesko 3 má na fukčnom čele 31 vytvorený otvor 311. Výška priečok 22 je menšia ako výška bočníc 21 a polomer zakrivenia bočných stien 221 priečok 22 je väčší ako polomer obvodovej plochy 32 valivého telieska 3.3. The rolling element 3 has an opening 311 formed on the blower face 31. The height of the crossbars 22 is less than the height of the sidewalls 21 and the radius of curvature of the side walls 221 of the crossbars 22 is greater than the radius of the peripheral surface 32 of the rolling body 3.

Pri montáži kompletného ložiska sa najskôr do káps 24 segmentov 2 osadia všetky valivé telieska 3 a takto pripravené segmenty 2 sa uložia na vnútorný krúžok 5 ložiska vedľa seba tak, že susediace segmenty 2 sa navzájom dotýkajú svojimi čelnými plochami 213 až je klietka J_ uzavretá po celom obvode. Následne sa na klietku uloží vonkajší krúžok 4. Valivé telieska 3 sa do káps 24 segmentov 2 osadia tak, že otvorom 311 vytvorenom na fukčnom čele 31 sa jednotlivé valivé telieska 3 postupne nasunú na výstupky tvoriace záchyty 23 a miernym tlakom, v dôsledku pružnej deformácie bočníc 21 sa zasunú dovnútra kapsy 24. Po uložení valivého telieska 3 do kapsy 24 sa v dôsledku pružnosti vrátia bočnice 21 do pôvodnej polohy, čím je valivé teliesko 3 zabezpečené proti vypadnutiu z kapsy 24 pri montáži kompletného ložiska.When assembling the complete bearing, all the rolling elements 3 are first mounted in the pockets 24 of the segments 2 and the segments 2 thus prepared are mounted side by side on the inner bearing ring 5 so that the adjacent segments 2 contact each other with their end faces 213 until the cage 1 is closed all over circuit. Subsequently, the outer ring 4 is placed on the cage. The rolling elements 3 are fitted in the pockets 24 of the segments 2 by sliding the individual rolling elements 3 successively onto the projections forming the catches 23 with slight pressure due to the elastic deformation of the sidewalls. After inserting the rolling element 3 into the pocket 24, the sidewalls 21 return to their original position due to the elasticity, thereby securing the rolling element 3 from falling out of the pocket 24 when the complete bearing is mounted.
