关节轴承

关节轴承是一种球面滑动轴承，其滑动接触表面是一个内球面和一个外球面，运动时可以在任意角度旋转摆动，

它采用表面磷化、炸口、镶垫、喷涂等多种特殊工艺处理方法制作而成。

关节轴承具有载荷能力大，抗冲击，抗腐蚀、耐磨损、自调心、润滑好等特点。

Knuckle-bearing is a spherical plain bearing, its sliding contact surface is an inner sphere and an outer sphere, 

which can rotate and swing at any Angle when moving, it is made of surface phosphating, blasting, insert pad, 

spraying and other special process processing methods. 

Joint bearing has the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication and so on.

—简介

                  关节轴承的结构比滚动轴承简单，其主要是由一个有外球面的内圈和一个有内球面的外圈组成。关节轴承一般用于速度较低的摆动运动(即角运动)，由于滑动表面为球面形，亦可在一定角度范围内作倾斜运动(即调心运动)，在支承轴与轴壳孔不同心度较大时，仍能正常工作。

                     The structure of the joint bearing is simpler than that of the rolling bearing, which is mainly composed of an inner ring with an outer sphere and an outer ring with an inner sphere. Joint bearings are generally used for low speed swing movement (that is, angular movement), because the sliding surface is spherical, it can also be tilted within a certain Angle range (that is, aligning movement), when the supporting shaft and the shaft shell hole are not concentric, it can still work normally.

—特点

                      关节轴承具有载荷能力大，抗冲击，抗腐蚀、耐磨损、自调心、润滑好等特点。根据其不同的类型和结构，可以承受径向负荷、轴向负荷或径向、轴向同时存在的联合负荷。由于在内圈的外球面上镶有复合材料，故该轴承在工作中可产生自润滑。一般用于速度较低的摆动运动，和低速旋转，也可在一定角度范围内作倾斜运动，当支承轴与轴壳孔不同心度较大时，仍能正常工作。自润滑关节轴承应用于水利、专业机械等行业。

                      Joint bearing has the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication and so on. According to its different types and structures, it can withstand radial load, axial load or radial and axial combined load. Since the outer sphere of the inner ring is inlaid with composite material, the bearing can be self-lubricating in operation. Generally used for low speed swing movement, and low speed rotation, can also be tilted in a certain Angle range, when the supporting shaft and the shaft shell hole concentricity is large, it can still work normally. Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.

—应用

            关节轴承广泛应用于工程液压油缸,锻压机床,工程机械,自动化设备，汽车减震器，水利机械等行业。关节轴承是球面滑动轴承，基本型是由具有球形滑动球面接触表面的内、外圈组成。根据其结构和类型的不同，可承受径向载荷、轴向载荷，或者是径向、轴向同时作用的联合载荷。

            因为关节轴承的球形滑动接触面积大，倾斜角大，同时还因为大多数关节轴承采取了特殊的工艺处理方法，如表面磷化、镀锌、镀铬或外滑动面衬里、镶垫、喷涂等，因此有较大的载荷能力和抗冲击能力，并具有抗腐蚀、耐磨损、自调心、润滑好或自润滑无润滑污物污染的特点，即使安装错位也能正常工作。因此，关节轴承广泛用于速度较低的摆动运动、倾斜运动和旋转运动。

                        Knuckle bearings are widely used in engineering hydraulic cylinders, forging machine tools, construction machinery, automation equipment, automotive shock absorbers, hydraulic machinery and other industries. The knuckle bearing is a spherical plain bearing, and the basic type is composed of an 

inner and outer ring with a spherical sliding spherical contact surface. Depending on its structure and type, it can withstand radial load, axial load, or the combined load of radial and axial action at the same time.

Because the spherical sliding contact area of the knuckle-bearing is large, the inclination Angle is large, and because most of the knuckle-bearing adopts special process treatment methods, such as surface phosphating, galvanized, chrome plating or external sliding surface lining, inserts, spraying, etc., it has a 

large load capacity and impact resistance. It has the characteristics of corrosion resistance, wear resistance, self-aligning, good lubrication or self-lubrication without lubricating dirt pollution, and can work normally even if the installation is misplaced. Therefore, joint bearings are widely used in low speed swing 

motion, tilt motion and rotary motion.
