Samoravnani kroglični ležaj


Samoravnan kroglični ležaj

Samonaravnajoči kroglični ležaji so kroglični ležaji z dvema vrstama kroglic (imenovanih "dirke"). Notranji obroč ima dve tekalni stezi, zunanji obroč pa ima sferično tekalno stezo, katere središče ukrivljenosti sovpada z osjo ležaja. Na ta način se lahko os notranjega kroga, krogle in kletke upogne okoli središča ležaja, s čimer se samodejno popravi neusklajenost, ki jo povzročijo napake pri obdelavi ali montaži ležajnega ležišča in gredi.

Na voljo so za odprto ali zapečateno. Ležaji so neobčutljivi na kotno neusklajenost gredi glede na ohišje.

Vrste samouravnavnih krogličnih ležajev:

Samouravnavni kroglični ležaji lahko zagotovijo različne velikosti, materiale in vrste glede na potrebe potrošnikov, vključno s posebno industrijsko uporabo, kot so aplikacije pri visokih temperaturah.

Imajo tri glavne samonastavljive kroglične ležaje: samonaravnalne kroglične ležaje odprtega tipa, zapečatene samonastavljive kroglične ležaje in samonastavljive kroglične ležaje z razširjenim notranjim obročem. Odvisno od uporabe jih je mogoče izdelati tudi v različnih velikostih in obremenitvah, od miniaturnih krogličnih ležajev za lahke obremenitve in okrasnih komponent do velikih samonastavljivih krogličnih ležajev.

Self-aligning Ball Bearings Construction

Self-aligning ball bearings consist of an outer ring, an inner ring, rolling elements, a cage to house the rolling elements, and seals that protect the balls from contaminants and other dirt. Due to their design, these elements make it possible for self-aligning bearings to counteract any static or dynamic misalignment of a shaft and housing assembly up to 3°. They also generate far less heat than other bearings due to the majhno trenje within the bearing, allowing them to run cooler than other bearings at higher speeds.

  • Outer Ring: The outer ring of the bearings has a smooth spherical shape without raceways. The shape of the outer ring allows for slight movement within the bearing, which in turn allows the bearing to self-align.
  • Notranji obroč: The inner ring of the self-aligning bearing has two raceways that keep the balls and cage in place.
  • Rolling elements and cage: The rolling elements on self-aligning ball bearings are kept in place by the cage and the inner ring. As there is a loose configuration between the balls and the inner and outer ring, friction and frictional heat are very low. The cage is typically stamped steel, PA66, reinforced glass fiber, or machined brass.
  • Pečat: A sealed self-aligning ball bearing ensures dirt and other contaminants don’t affect the bearing rolling elements.

Self Aligning Ball Bearing Advantages

  • Accommodate static and dynamic misalignment
    The bearings are self-aligning like spherical roller bearings.
  • Excellent high-speed performance
    Self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.
  • Minimalno vzdrževanje
    Because of low heat generation, the bearing temperature is lower, leading to extended bearing life and maintenance intervals.
  • Nizko trenje
    Very loose conformity between balls and outer ring keeps friction and frictional heat at low levels.
  • Excellent light load performance
    Self-aligning ball bearings have low minimum load requirements.
  • Nizka raven hrupa
    Self-aligning ball bearings can reduce noise and vibration levels, for example, in fans.

Self Aligning Ball Bearing Disadvantages

Self Aligning Ball Bearing Disadvantages

  • Load-types: The ball bearings on self-aligning ball bearings are mounted at a relatively straight angle between the inner and outer ring. This means that the load types the bearing can handle is radial, with little axial load carrying capacity.
  • Load-amount: As ball bearings have a small point of load-bearing contact, the amount of load this type of bearing can handle is relatively small.

Installing a Self-aligning Ball Bearing on the Adapter Sleeve

    1. Bearings often come with a protective film that protects the components from outside influences during transport. Make sure to remove this film before mounting the bearing
    2. Oil the exterior surface of the bearing with oil or grease.
    3. Apply oil to the adapter.
    4. Open the adapter slightly with the help of a screwdriver and slide it in place on the shaft.
    5. Once the adapter is in the correct position, position the bearing on the adapter sleeve. If the shaft has threads, it will help to use a nut to bring the bearing in the correct place; if not, use a bearing pusher kit or a small mallet.
    6. Once the bearing is in place, test the rotation of the bearing on the outer ring. It should be able to rotate freely, but not swivel.
    7. Lock the bearing in place with a locking washer by first removing the nut, placing the washer in place, and putting the nut back again.
Note: If the adapter sleeve is loose or not properly secured in place, the inner ring can start turning on the adapter sleeve. This causes excessive friction between the three components and can damage the shaft, adapter, and bearing.

Self Aligning Ball Bearing Application

Given the benefits of the self-aligning ball bearing, there are several industries that can use them, including:

• Textile

• Mining

• Heavy machinery

• Power machinery

• Agricultural

If you’re dealing with issues like misalignment in your applications, it can be difficult to operate efficiently. Self-aligning ball bearings can help you with that problems.
