introduction：Knuckle bearing（spherical plain bearing）Have two“fit”Spherical contact surface，This contact is called coordinated contact。The calculation method of mechanical characteristics of joint bearing plays an important role in the structural design and wear analysis of joint bearing。It is a very complicated problem to coordinate the calculation of surface contact pressure，existingHertzThe model is limited to elastic half-space，It cannot be used to calculate the spherical coordinated contact pressure distribution。There is a unified model of spherical contact，namelyFangmodel，It can solve the problem of contact pressure distribution of small deformed spherical surface，This model is suitable for both non-coordinated contact and coordinated contact。However, the contact area of the joint bearing is not a complete spherical surface，The contact pressure distribution should be further calculated on the basis of the complete spherical coordinated contact model。In addition，Free boundary effect will also appear in the use of joi

introduction：SKFIntroduction to high precision bearings： 1、High-precision bearing selection： High precision bearings refer to rotation accuracy、Bearings with high dimensional accuracy and low surface roughness，In our standardsP4Level and aboveP4Step bearing，Such asP2Grade 1 bearings are high precision bearings，This is roughly in line with American standardsABEC 7andABEC 9fairly，International standardISO P4andP2fairly，International standards are recognized and adopted by many countries，Like Japan，Germany and France, etc。 By precision machining，Various types of rolling bearings can achieve high precision requirements，However, the most commonly used high-precision bearings in applications are angular contact ball bearings，And in high precision with high stiffness requirements of gold It is the main shaft of the cutting machine，The use of double-row short cylindrical roller bearings is also many，The second is tapered roller bearings。Current，Due to the development of bearing processing technology，The internatio

introduction：My name is aligning ball bearing，nickname1Class bearing。Look at my name alone, you can see that my biggest characteristic is“Regulating the mind”。In that way“Regulating the mind”In what way is it specific？ Aligning ball bearings： Each type of bearing has its working environment，Because engineers will consider many factors when designing，All bearing hole center and shaft center sometimes have a certain Angle，Aligning ball bearings can be automatically adjusted to adapt to this Angle，To ensure the normal operation of the equipment，This is the meaning of the heart。It needs to be stressed，If it works properly，The error of this included Angle shall not exceed3The degree of，The relative inclination is small，So you have to pay attention。Aligning ball bearing cages are mainly made of steel plate and synthetic resin，Mainly bear radial load，At the same time, it can also withstand small axial loads。 Self-aligning roller bearings： Aligning ball bearings are widely used in the industry，The coverage rate has
