Bearing concept
Bearings Bearings are used a lot in life, so if the bearings are damaged and not replaced, it will lead to the damage of related parts, causing a lot of costs to repair and damage to product productivity. quota. In particular, they can also make the vehicle heavier and damage the axle or even damage the bearing housing.
WHAT IS A SILVER BEARING?
Bearings have the function of supporting the center shaft, transmission shaft and rotating parts, ensuring rotational motion and supporting the load acting on the above components. Equivalent terms of Bearing can use words like Bearing, Bearing, Rolling Bearing, Bearing…etc. It all refers to a product collectively called “Bearing”. Bearings have the function of supporting the center shaft, transmission shaft and rotating details, ensuring rotation and supporting the load acting on the above details. This is a very important mechanical moving detail. And often they are called bearings because to distinguish it from oil bearings – a type of plain bearings. The inside of the ball bearing is a sliding bearing with spherical or straight cylindrical or tapered balls to create rolling friction for the bearing.
However, not all types of loads are created equal. There are two types of bearings with different load capacities: radial load (radial load) and axial or thrust load (axial load). Bearings give the shaft or frame the ability to move freely within a rotating shaft. The loads that the bearings will endure will be in two basic directions. Radial load will act at the right angle of the bearing (the axis of rotation of the bearing), which can be understood as the force acting on the circumference of the part through the radius. Axial loads operate parallel to the rotating bearing (the force acting on the machine shaft). Most bearings handle both radial and axial loads.
STRUCTURE OF SILVER BEARINGS
A ball bearing will consist of 4 main parts: outer ring, inner ring, roller and separator ring. In addition, industrial bearings also have one more part, the seal.
Inside:
1. Outer ring and inner ring
- A ball bearing will have the outer ring fixed to the housing. And the inner ring will be fixed to the machine shaft. In addition, depending on the type of ball, the inner face of the bearing has a spherical or conical groove
2. Roller
- Different ball bearings will have different rollers. So each type of roller will correspond to a different type of bearing. The material of the roller depends on the impact load, but the typical composition is mainly carbon steels containing a certain amount of chromium and manganese.
- In particular, there are some common rollers such as: spherical rollers (spherical bearings), drum rollers (drum bearings), tapered rollers (taper bearings), cylindrical rollers (cylindrical bearings). and needle rollers (needle bearings)…
3. Separator ring
- The separator ring is what is used to position the ball at fixed distances between the ball tracks. Usually, there will be 3 main types, which are steel, copper and plastic cages.
- Depending on the material of the cage, they will have different advantages and disadvantages. In work, too, depending on the specific application, the user will have ways to choose the appropriate type of cage.
4. Seals
- In addition to the above 4 main parts, some types of bearings will be retrofitted with the purpose of keeping grease and preventing dust. Also depending on the application, the seal will be made of iron or plastic.
- Due to the need to use different types of machines, manufacturers have produced bearings with different shapes to meet different uses. In order to optimize the bearing capacity of the bearings are: Ball bearings, symmetrical drum rollers, asymmetrical drum rollers, cylindrical rollers, needle rollers, tapered rollers…
CLASSIFICATION OF SILVER BEARINGS
1. According to the roller shape
- Bi
- Short cylindrical chopsticks, long cylindrical chopsticks
- Chopsticks
- Symmetrical or asymmetrical drum-shaped wand
- Needle chopsticks
- Twisted chopsticks
2. According to load capacity
- Bearing: Bearing only radial loads and part of the axial forces (bearings), or only radial loads (short cylindrical roller bearings).
- Thrust bearing: Withstands both radial and axial loads (blocking roller bearings, tapered roller bearings)
- Bearing bearing: Mainly axial load, and also a part radial load
- Bearing: Bearing only axial load
3. According to the number of roller rows
- Single row drive
- Double-row drive
- Four-row drive
4. According to the drive size
- Super light drive
- Exceptionally light drive
- Light drive
- Wide light drive
- Central drive
- Wide medium drive
- Heavy drive
5. According to the ability to self-selection
- Capable of self-selection
- Inability to self-select
