How to choose the bearing type?

2020-01-11



Answer

Bearing equipment occupies machinery space and position

In mechanical design, generally determine the size of the shaft, and then select the rolling bearing according to the size of the shaft. Ball bearings are usually used for small shafts and roller bearings are used for large shafts. However, when the bearing is limited in the diameter direction of the machine, needle roller bearings, extra-light and ultra-light series ball or roller bearings are used; when the axial position of the bearing is limited in the machine, narrow or special Narrow series of ball or roller bearings.

The size, direction and nature of the load on the ball bearing

Load is the most important factor in bearing selection. Roller bearings are used to bear heavy loads, ball bearings are used to bear light or medium loads, and bearings made of carburized steel or bainite hardened can withstand shock and vibration loads.

In the direction of the load, when bearing pure radial load, you can choose deep groove ball bearings, cylindrical roller bearings or needle roller bearings. When bearing a small pure axial load, a thrust ball bearing can be used; when bearing a large pure axial load, a thrust roller bearing can be used. When the bearing bears combined radial and axial loads, angular contact ball bearings or tapered roller bearings are generally used. For cantilever support structures, tapered roller bearings or angular contact ball bearings are often used and are used in pairs.

Self-aligning performance of bearings

When the centerline of the shaft is different from the centerline of the bearing housing, there is an angular error, or the rigidity of the shaft is small due to the large distance between the two supports of the shaft, and it is easy to bend or tilt under force, you can choose a good adjustment Heart ball or spherical roller bearings, and outer ball bearings. This type of bearing can maintain normal operation when the shaft is slightly inclined or bent.

Bearing rigidity

The rigidity of the bearing refers to the amount of force required for the bearing to deform per unit. The elastic deformation of rolling bearings is very small, which can be ignored in most machines, but in some machines, bearing rigidity is an important factor. Generally, cylindrical and tapered roller bearings should be used. Because these two types of bearings are under point load, their rolling bodies and raceways are in point contact, and their rigidity is poor.

In addition, various types of bearings can also be pre-tensioned to achieve the purpose of increasing the support rigidity. Such as angular contact ball bearings and tapered roller bearings, in order to prevent the vibration of the shaft and increase the support rigidity, a certain axial force is often applied in advance during installation to make them compact.

Bearing speed

Each bearing model has its own limit speed, which is determined by physical characteristics such as size, type and structure. The limit speed refers to the maximum working speed of the bearing (usually r ∕ min). As a result, the bearing temperature rises, the lubricant dries up, and even the bearing gets stuck.

The speed range required in the application occasion helps to determine what type of bearing to use. D is the bearing size, which usually refers to the pitch circle diameter of the bearing. When selecting a bearing, use the average value of the bearing inner diameter and outer diameter, in mm. Multiply the pitch circle diameter D by the shaft rotation speed (unit r / min) to obtain a limiting speed factor (DN). DN is very important when selecting the bearing type and size. Most bearing manufacturers' product catalogs provide the limit speed value of their products. Practice has proved that it is better to work under the condition of 90% lower limit speed.
Bearing travel and axial displacement

Normally, a shaft is supported by two bearings separated by a certain distance. In order to adapt to the different degrees of thermal expansion of the shaft and the casing, one bearing should be fixed in the axial direction during installation, and the other bearing should be able to swim on the shaft (ie, floating support) to prevent the shaft from expanding or contracting Stuck phenomenon caused. Traveling bearings usually use cylindrical roller bearings (formerly 2000 and 32000) and needle roller bearings with no ribs in the inner ring or outer ring. This is mainly because the internal structure of such bearings allows the shaft and housing to have proper axial displacement. . At this time, the inner ring and the shaft, the outer ring and the hole of the housing can be tightly matched. When non-separable bearings are used for swimming support, such as deep groove ball bearings and spherical roller bearings, the outer ring must be allowed to fit the outer shell hole, or the inner ring and shaft should be loosely fitted to make it axially Free to swim. Tapered roller bearings, spherical roller bearings and deep groove ball bearings are basically of the positioning type, and when used as non-positioning, loose fit installation is used. All thrust roller bearings are positioning bearings.

Facilitates bearing installation and disassembly

When choosing a bearing type, whether it is convenient to install and remove the bearing must also be considered comprehensively, especially for the installation and removal of large and extra large bearings. General angular contact ball bearings, tapered roller bearings, cylindrical roller bearings and needle roller bearings with separable outer ring are easy to install and disassemble. Their inner and outer rings can be installed on the shaft or the housing hole, respectively. In addition, self-aligning roller bearings, double-row cylindrical roller bearings and self-aligning ball bearings with tapered bores and tapered sleeves on the inner diameter are also easier to install and remove.

other request

In addition to the above factors, the working environment temperature of the bearing, bearing seal, and special requirements for friction torque, vibration, noise, etc. should also be considered.

Bearing function and classification

2020-01-11



Answer

(1) Classification of bearings Bearings are divided into two categories: sliding bearings and rolling bearings.
⒈Classification of sliding bearings ⑴ According to the direction of bearing load, it is mainly divided into radial sliding bearings and thrust sliding bearings. ⑵ According to the type of lubricant, it can be divided into oil-lubricated bearings, grease-lubricated bearings, water-lubricated bearings, gas bearings, solid-lubricated bearings, magnetic fluid bearings and electromagnetic bearings.
⑶ According to the thickness of the lubricating film, it can be divided into two types: film lubricating bearings and thick lubricating bearings
⑷ According to the bearing material, it can be divided into bronze bearings, cast iron bearings, plastic bearings, gemstone bearings, powder metallurgy bearings, self-lubricating bearings and oil-containing bearings.
⑸ According to the bearing structure, it can be divided into round bearings, elliptical bearings, three-oil leaf bearings, stepped surface bearings, tilting pad bearings and foil bearings.
2. Classification of rolling bearings
The main types of rolling bearings are self-aligning ball bearings, spherical roller bearings, tapered roller bearings, thrust ball bearings, deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings and needle roller bearings.

(B), the introduction of the function of the bearing
1. Function of sliding bearing The sliding bearing works smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, and friction loss and surface wear can be greatly reduced. The oil film also has a certain vibration absorption capacity.
2. The function of the rolling bearing It supports the rotating shaft and the parts on the shaft, and maintains the normal working position and rotation accuracy of the shaft. The rolling bearing is easy to use and maintain, reliable in operation, good in starting performance, and has a high carrying capacity at medium speed. Compared with the sliding bearing, the rolling bearing has a larger radial size, poor vibration damping capacity, low life at high speed, and loud noise.
3. Function introduction of each rolling bearing
(1) Self-aligning ball bearings are self-aligning and suitable for shafts with multiple fulcrums and insufficient bending stiffness.
(2) Spherical roller bearings are self-aligning, withstand a large radial load and a small amount of axial load, and resist vibration and shock.
(3) Tapered roller bearings can withstand large radial loads and axial loads at the same time. The outer ring is separable, the clearance is adjustable, and it is convenient to install and dismount. It is suitable for shafts with greater rigidity, generally used in pairs and installed symmetrically.
(4) Thrust ball bearings can only bear axial loads, and the load action line must coincide with the axis. Single-row ball bearings can only bear one-way axial load; double-row ball bearings can bear two-way axial load. The bearing is suitable for occasions with large axial load but low speed.
(5) Deep groove ball bearings can bear radial load and a certain amount of axial load. When the speed is high and the axial load is not too large, it can replace the thrust ball bearing to bear pure axial load. Suitable for high-speed rotation and occasions requiring low noise and low vibration. This is the most representative bearing. (6) Angular contact ball bearings can simultaneously bear radial and axial combined loads. The larger the nominal contact angle, the greater the axial load carrying capacity. Mainly suitable for high-speed and high-precision rotation.
