Spherical bearing specification, selection of clearance and after installation of lubrication

Spherical bearing specification, selection of clearance and after installation of spherical bearing lubrication model there are many kinds of specifications, the author in this not, for example, one by one, a want to know the spherical bearing product specifications can choose our mall website understanding! The author first gave us a brief introduction of spherical bearing product knowledge! Working principle of spherical bearing as the human body joint, is widely used in the moving parts of the airplane wings, the airplane engine connected to the wing sections, aircraft, all kinds of door switch, and a helicopter, trains, motor vehicles, power plants, construction machinery, ships, play equipment, aerospace, and many other fields. Spherical bearing clearance choice: bearing conditions of use, which the bearing rotating speed, temperature, fit tolerance are directly related to the selection of the bearing clearance. Generally under 3500 RPM speed motor mostly adopts CM clearance, such as high temperature and high speed motor, require the use of relatively large clearance. Use a tight fit, both inside and outside temperature difference is bigger, need to reduce the friction torque and deep groove ball bearings under high axial load or need improve heart function, appropriate USES large clearance group. When high rotating accuracy requirement or needs to strictly limit the axial displacement, appropriate USES small clearance group. The characteristics of the spherical bearing series products: it is between the ball and body through the injection molding method ( INJECTIONMOLD) Form has self-lubrication resin ( In nylon resin added teflon? A kind of material) 。 The product with teflon types, without will be woven lining cloth or adhesive, batch production ability is excellent, so the production cost is low. In addition, since the lubricating type can free maintenance, and good wear resistance of the bearing. Used for dynamic load, the more durability than ordinary metal mold. Especially in a one-way load for micro movement can show its good characteristics. Spherical bearing installation: the installation of the bearings in a dry, clean environment, should be prepared before installation all the necessary parts, tools and equipment, should carefully check the shaft and the inner ring with the quality and check the presence of burrs, ensure the installation surface cleaning and smoothness. Spherical bearing lubrication: after installation is mainly under the condition of the normal operation of bearing, and direct contact surface of raceway and rolling to the body, reduce the bearing internal friction and wear, improve the bearing performance, prolong the service life of bearing, the common way of lubricating grease lubrication and oil lubrication and three kinds of solid lubrication. Grease in the general case, the most widely used, its bearing, seal structure and lubrication facility is simple, easy maintenance, have prevent water, gas, dust and other harmful impurities into the inside of the bearing capacity. Oil lubrication is mainly applied to overload, high speed, high temperature, etc, these occasions good lubricating oil flow, grease lubrication effect is better than that of the common lubrication oil bath lubrication, oil drip lubrication, splash lubrication, circulating oil lubrication, splash lubrication, oil mist lubrication oil lubrication, etc. ; Solid lubrication in certain occasions, in the case of grease lubrication and restricted, such as high temperature and vacuum conditions.
