Machine specific, please describe the specific points
Many types of bearings. According to the direction of the load it can withstand can be divided into: the radial bearing, also known as radial bearings, bearing radial load. The thrust bearing, and thrust bearing, bear the axial load. The radial thrust bearing, also called centripetal thrust bearing under radial load and axial load at the same time according to the nature of work. The friction bearing can be divided into different sliding friction bearings (the sliding bearing) and rolling friction bearings (the rolling bearing) two categories.Angular contact bearings: ball and raceway nominal contact angle greater than 0 degrees, the rolling bearing and less than 90 degrees. At the same time can bear radial load and axial load. Can work at a higher speed. The larger the contact angle, the axial bearing capacity is higher. The high precision and high speed bearings usually take 15 degrees contact angle in the axial direction. Under the action of force, will increase the contact angle. The axial load of ball bearings can only bear a direction, in radial load, will cause additional axial force. The axial displacement and can limit shaft or shell in one direction. If the duplex mounting, so that a pair of bearing outer ring relatively, i.e. the wide end of the wide end, the narrow end face with narrow end. So to avoid the additional axial force, but also in the two direction of the shaft or shell limit in the axial clearance range.
Outer spherical bearings: spherical roller bearings with wide outer rings and outer rings with locking elements. Mainly for simple housingsLinear motion bearing: two roller, in the direction of rolling has relatively linear motion of rolling bearingsBall bearing: the rolling body is the rolling bearing of the ballDeep groove ball bearings: ball bearing continuous groove of each ring has a cross section of the ball about three weeks of the raceway, suitable for precision instruments, low noise motor, automobile, motorcycle and general machinery, is the most widely used type of bearings in machinery industry. Simple structure, use and maintenance convenient. Mainly used to bear radial load, also can withstand certain axial load, when the bearing radial clearance increased, with the performance of angular contact ball bearings, can withstand higher axial loads. The bearing friction coefficient is small, high limit speed, different size and forms. Solid and durable, strong versatility and low noise operation, easy to install and can be run at a high speed. The design of deep groove ball bearing and sealing, without lubrication and no maintenance. Separate with ball gap and double ball bearings, suitable for heavy load. Condition.Thrust ball bearings: rolling bodies are thrust ball bearingsRoller bearings: rolling bodies are roller bearingsCylindrical roller bearings: rolling bodies are cylindrical roller radial roller bearings, is a separate type bearings, installation and disassembly is very convenient. Cylindrical roller bearings are divided into single, double and four column
