Vlečni kroglični ležaj


Vlečni kroglični ležaj

Potisni kroglični ležaj je zasnovan tako, da zdrži potisno obremenitev pri visoki hitrosti in je sestavljen iz podložnih obročev z utorom za kroglično kotalno stezo. Poleg tega lahko ti ležaji prenesejo aksialne obremenitve, ne pa tudi radialnih. Ker je obroč v obliki sedeža, so potisni kroglični ležaji razdeljeni na dva tipa: tip blazine z ravnim dnom in tip sferične blazine za poravnavo.

Composition of Thrust Ball Bearing:
Potisni kroglični ležaj je sestavljen iz treh delov: sedežnega obroča, obroča gredi in sklopa kroglične kletke – obroč gredi se ujema z obročem gredi in sedežni obroč v primerjavi z ohišjem.

Thrust Ball Bearing Types:
According to the force, it is divided into unidirectional thrust ball bearing and bidirectional thrust ball bearings. A one-way thrust ball bearing can take a one-way axial load. Bidirectional thrust ball bearing can withstand bidirectional axial load, wherein the shaft ring and shaft match. The mounting surface of the seat ring is spherical bearing with self-aligning performance, which can reduce the influence of installation error.

How Do Thrust Ball Bearings Work?

Most thrust ball bearings use balls to support the machines with which they are used. Known as “thrust ball bearings,” they contain many small metal balls in a band around the perimeter. You can see an example of a thrust ball bearing in the photo above. Thrust ball bearings such as this are used in applications where a machine’s moving parts apply an axial load. With their arrangement of balls, they are able to assist with the rotation of a machine’s moving parts.

There are other types of thrust bearings as well. In addition to thrust ball bearings, there are cylinder thrust bearings. Cylinder thrust bearings feature cylindrical-shaped rollers that point towards the axis. Another type of thrust bearing is magnetic. Magnetic thrust bearings live up to their namesake by producing a magnetic field. They are made of ferromagnetic materials that produce a magnetic field. The presence of this magnetic field helps to support the axial thrust. Of all the different types, though, none are more popular than thrust ball bearing.

How Thrust Ball Bearings Work

Thrust Ball Bearing Features and Benefits:

  • Two designs available:  single direction and double direction.
  • Za prilagoditev začetnih neusklajenosti sklopa sta na voljo obe izvedbi s sferičnimi poravnanimi sedeži ali podložnimi podložkami sedežev.
  • High quality steel – Ultra clean steel extends bearing life by up to 80%.
  • Advanced grease technology – Special lubricants that can extend grease life and performance.
  • High grade balls – Smooth and quiet operation even at high speeds
  • Optional seating rings take initial misalignment.

Thrust Ball Bearing Application:

A variety of applications and industries rely on thrust ball bearings, such as centrifuges and various medical equipment. Other common applications include:

    • Avtomobilizem. Thrust ball bearings are used in vehicles to support axial forces caused by helical gears in modern vehicle gearboxes. They are also ideal for higher speed automotive applications that require oil lubrication.
    • Prevoz. Thrust ball bearings are very important for the transportation industry as they allow for more powerful and improved engines and propellers.
    • Generators and water turbines. Certain types of thrust ball bearings are capable of reducing friction and drag, making them ideal for generators and water turbines.
    • Heavy-Duty Machinery. Thrust ball bearings with high load ratings are suitable for heavy-duty machinery, such as drills and cranes.
    • Industrial Machinery. Several types of industrial machinery have a need for rotating shafts, making thrust ball bearings a crucial component.
    • Mining & Construction. Thrust ball bearings are typically made using corrosion-resistant materials, allowing them to support axial loads in equipment used in demanding mining and construction environments.
Thrust Ball Bearing Application

Thrust Ball Bearing Installation Steps

Usually, the thrust ball bearing installation steps are: install the lower washer, and then the cage and bearing steel balls, at the last one is upper washer. The upper washer can fix the axis and rotate with it. Here are the steps in details with pictures demonstration.

Step 1: Prepare one set of thrust ball bearing parts, including lower washer, upper washer and cage with steel balll assembly.

Step 2: Place the lower washer / shaft washer (in practical application, this part is close to the stationary part) as shown in the following picture.

Step 3: Install the cage with steel ball assembly above the lower washer (shaft washer).

Step 4: Install the upper washer (housing washer) as shown in the following picture.

Step 5: A simple thrust ball bearing was installed completely as shown in the following picture.

The fitting of thrust ball bearings with axis in general is for transition, and fitting of the ring with the bearing bore is clearance fit. Therefore, this kind of bearings is easier to install. Bi-directional thrust ball bearings shaft spring should be fixed on the axis to prevent relative rotation to the axis.

Thrust Ball Bearing Manufacturers

Thrust ball bearing manufacturers manufacture a wide range of these bearings that are used in a variety of applications. They provide a solid, maintenance-free, and corrosion-resistant option that can accommodate both radial and axial loads. The bearings also offer an increased life span due to a higher quality steel construction.

When looking for thrust ball bearings, it is important to choose one that has the right diameter. Bearings of this type can be found in both single and double-direction styles, and their outer raceways can be grooved or ungrooved. Aside from the size, the shaft height and the axis of the shaft are important considerations. In addition, a high-quality bearing can also be manufactured to provide the highest rollability.

Thrust bearings can be produced using a variety of different materials. For example, stainless steel, aluminum, and nickel alloys can be manufactured. The rolling elements are also available in different sizes and finishes. This allows the end user to select the lubricant they wish to use. Most thrust bearings are used in a low-speed, axial-load application. Despite the fact that they can support a high-load, they are not suitable for use in a high-speed, radial-load application. However, they are a good choice for applications that do not require precision.
