Thrust bearing (original) (raw)
Un cojinete de empuje (también denominados cojinetes axiales) es un tipo particular de cojinete diseñado para soportar una carga predominantemente axial. Existen diseños tanto con rodillos internos (rodamientos propiamente dichos), como sin ellos (los cojinetes de película fluida o los magnéticos).

(es) A thrust bearing is a particular type of rotary bearing. Like other bearings they permanently rotate between parts, but they are designed to support a predominantly axial load. Thrust bearings come in several varieties. * Thrust ball bearings, composed of bearing balls supported in a ring, can be used in low thrust applications where there is little axial load. * Cylindrical thrust roller bearings consist of small cylindrical rollers arranged flat with their axes pointing to the axis of the bearing. They give very good carrying capacity and are cheap, but tend to wear due to the differences in radial speed and friction which is higher than with ball bearings. * Tapered roller thrust bearings consist of small tapered rollers arranged so that their axes all converge at a point on the axis of the bearing. The length of the roller and the diameter of the wide and the narrow ends and the angle of rollers need to be carefully calculated to provide the correct taper so that each end of the roller rolls smoothly on the bearing face without skidding. These are the type most commonly used in automotive applications (to support the wheels of a motor car for example), where they are used in pairs to accommodate axial thrust in either direction, as well as radial loads. They can support greater thrust loads than the ball type due to the larger contact area, but are more expensive to manufacture. * Spherical roller thrust bearings use asymmetrical rollers of spherical shape, rolling inside a house washer with a raceway with spherical inner shape. They can accommodate combined radial and axial loads and also accommodate misalignment of the shafts. They are often used together with radial spherical roller bearings. Spherical roller thrust bearings offer the highest load rating density of all thrust bearings. * Fluid bearings, where the axial thrust is supported on a thin layer of pressurized liquid—these give low drag. * Magnetic bearings, where the axial thrust is supported on a magnetic field. This is used where very high speeds or very low drag is needed, for example the Zippe-type centrifuge. Thrust bearings are commonly used in automotive, marine, and aerospace applications. They are also used in the main and tail rotor blade grips of RC (radio controlled) helicopters. Thrust bearings are used in cars because the forward gears in modern car gearboxes use helical gears which, while aiding in smoothness and noise reduction, cause axial forces that need to be dealt with. Thrust bearings are also used with radio antenna masts to reduce the load on an antenna rotator. One kind of thrust bearing in an automobile is the clutch "throw out" bearing, sometimes called the clutch release bearing. (en) スラスト軸受（スラストじくうけ、英語：thrust bearing）は、回転する物体の軸方向に働く力（スラスト、推力）を受け止める軸受である。スラスト・ベアリングとも言う。 平歯車、滑車では円周方向の力を支えるラジアル･ベアリングのみで用が足りるが、はすば歯車、かさ歯車、ねじ歯車などでは負荷の掛かる回転時に軸方向に力が働き、かみ合いを減らすように作用する。この結果、異音を発したり寿命を縮めたりする。これを防ぐためにはスラスト軸受が不可欠である。 (ja) Een axiaallager is een lager dat ontworpen is om axiale krachten (krachten in de lengterichting van de as) op te nemen. Dit in tegenstelling tot de meeste overige lagers, die (hoofdzakelijk) radiale krachten (krachten haaks op de as) opnemen. Axiaallagers zijn er in de vorm van een taatslager en een kraaglager. Een taatslager is op het eind van een as geplaatst, terwijl een kraaglager op een doorlopende as geplaatst wordt. Een axiaallager kan een glijlager zijn (een bekend voorbeeld daarvan is de taats waarop de koningsspil van een molen rust), maar doorgaans is het een rollend lager, bijvoorbeeld een kogellager. Axiaallagers worden gebruikt voor alle toepassingen waarbij er druk op een roterende as wordt uitgeoefend. * Axiaal naaldlager * Cilindrisch axiaallager * Zelfcentrerend axiaallager (nl) |
