How to calculate the axial force of the bearing

1. The simple algorithm is resultant force, and the vector algorithm can be used for precise points

2. The theory of deep groove ball bearing does not derive axial force, but it will be subject to slight axial force in the process of practical application, because it has a certain centering effect. After the axial force disappears, it will return to the original position
the size of the axial force should be related to the actual working environment. After the axial force is applied, the force of the ball bearing is equivalent to having a contact angle, which is similar to the angular contact ball bearing. The axial force also has a great relationship with the clearance and radius of the bearing itself
especially the clearance, the larger the clearance is, the larger the range of motion of the ball in the axial position is, that is, the larger the axial clearance is, the greater the axial force it can bear, but the clearance can not be blindly large
in a word, I can tell you that the axial force is far less than the radial force. As for the specific calculation, because the contact angle is unpredictable, there is no way to know
the selection of deep groove ball bearing is unreasonable if the bearing is subjected to radial load and continuous axial load at the same time, because continuous axial force will rece the service life of deep groove ball bearing. Angular contact ball bearing or tapered roller bearing can be selected according to rotating speed and other instries and mines, and four point contact ball bearing can also be selected if bidirectional axial force is required, Double row tapered roller bearing or double row angular contact ball bearing.

3. Axial force refers to the force in the direction of bearing axis or parallel to the axis. Radial force means that the direction of the force is parallel to the line of diameter
calculation method: first, check the mechanical design manual, calculate the derived axial force s of tapered roller bearing, consider the positive and negative rotation of bearing, if there is external force, the axial force should also be considered, if there is the latter, consider whether it is relaxed or compressed, calculate s, then calculate the equivalent dynamic load P from s, and calculate the life l from the life formula. This is only the general steps, detailed steps also hope to refer to the relevant books.

4. The theory of deep groove ball bearing is not subject to axial force, but it will be subject to slight axial force in the process of practical application, because it has a certain centering effect. After the axial force disappears, it will return to the original position
the size of the axial force should be related to the actual working environment, and the force situation of the ball bearing after the axial force is equivalent to the contact angle, It is similar to angular contact ball bearing. The axial force has a lot to do with the clearance and radius of the bearing itself
especially the clearance, the larger the clearance is, the larger the range of motion of the ball in the axial position is, that is, the larger the axial clearance is, the greater the axial force it can bear, but the clearance can not be blindly large
in a word, I can tell you that the axial force is far less than the radial force. As for the specific calculation, because the contact angle is unpredictable, there is no way to know
if you can find the design method of Okamoto's deep groove ball, there should be a detailed introction above

5. Single row angular contact ball bearings can only bear axial load in one direction, which will cause additional axial force when bearing radial load. And it can only limit the axial displacement of shaft or shell in one direction. The contact angle of angular contact ball bearing is 40 degrees, so it can bear large axial load

6. In a strict sense, cylindrical roller bearing should not bear axial force in practical application, otherwise it will proce abnormal stress at raceway angle and cause bearing damage. The function of rib is actually used to guide roller end face. In fact, certain axial force has no relationship with the axial influence of bearing rib, lubrication state, working temperature and heat dissipation condition. In practical application, cylindrical roller bearing should be used together with other bearings which can bear axial load.

7. The theory of deep groove ball bearing is not subject to axial force, but it will be subject to slight axial force in the process of practical application, because it has a certain centering effect. After the axial force disappears, it will return to the original position. The magnitude of the axial force should be related to the actual working environment, and the force of the ball bearing after the axial force is equivalent to the contact angle, It is similar to angular contact ball bearing. The axial force has a lot to do with the clearance and radius of the bearing itself

especially the clearance, the larger the clearance is, the larger the range of the ball's movement in the axial position is, that is, the larger the axial clearance is, the greater the axial force it can bear, but the clearance can not be blindly large

in a word, I can tell you that the axial force is far less than the radial force. As for the specific calculation, because the contact angle is unpredictable, there is no way to know that if the shaft bears the radial load and the axial load continuously, the selection of deep groove ball bearing is unreasonable, because the service life of deep groove ball bearing will be reced if the axial force is continuously applied, Angular contact ball bearing or tapered roller bearing can be selected according to the rotating speed and other instries and mines. Four point contact ball bearing, double row tapered roller bearing or double row angular contact ball bearing can also be selected if axial force is required in both directions
