Concrete Vibrator Shaft/Flexible Drive Shaft (JYG8.10.11.12.13)

The joint bearing is a spherical sliding bearing, and the basic type is composed of the inner and outer rings with the contact surface of the spherical sliding sphere. The joint bearings are mainly composed of an inner ring with an outer sphere and a outer ring with an inner sphere, which can bear a large load. According to the different types and structures, the combined load of radial load, axial load or radial and axial force can be borne simultaneously. Because of the composite material inlaid on the outer sphere of the inner ring, the bearing can produce self lubrication in the work. Generally speaking, it can be used for low speed swing motion and tilt motion in a certain angle. When the bearing shaft and axle housing hole have different concentricity, they can still work normally. Self lubricating joint support is used in water conservancy, professional machinery and other industries. Because the spherical sliding contact area of the joint bearing is large and the inclination angle is large. At the same time, most of the joint bearings have taken special process treatment methods, such as surface phosphating, galvanizing, chrome plating or external sliding surface lining, padding, spraying and so on. Therefore, it has great load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self aligning, lubrication, or self lubrication, no dirt contamination. Even if the dislocation is installed, it can work normally. Therefore, the joint bearings are widely used for low speed swinging motion, tilt motion and rotation motion.

Rod end joint bearing
To select a type of bearing, to determine the required bearing size, the main factors to be considered are the load, the bearing capacity and the expected service life. This is the case when the joint bearing is selected.
The type according to the standard of GB/T9161 can be divided into: bending rod ball joint rod end bearings (type: SQ); straight rod ball joint rod end bearings (type: SQZ); single rod ball joint rod end bearings (type: SQD); left internal thread assembling rod end joint bearing (type: SLLB); left outer thread assembling rod end joint bearing (type: SALB); left bending rod type rod end bearings (type: SLLB); l single rod type rod end bearings (type: SQLD); with a cylindrical type welding rod end joint bearing (cylindrical) (type: SK); with flat seat type welding rod end bearings (Fang Xing) (type: SF); locking type rod end bearings (type code: SLR).
According to the size series

According to the size series
Rod End Bearing EH series (reinforced); rod end bearing EG series (reinforced type); British size rod end bearing joint normal series (size serial code Z); rod end bearing JK series (size series code JK). The structure material code and the clearance group code are like the joint bearings.
The rod end joint bearing is mainly used in the supporting parts of the low requirement of concentric degree, the high pressure of the working surface and the slow swing and rotary motion.
The detailed information of the rod end joint bearing should be consulted GB/T304,1-2002, GB/T304,2-2002, GB/T304,3-21102 and GB/12765-1991.

The rod end joint bearing, which belongs to the sliding bearing, has the wear-resistant non metal material lubricating type, and also has the oil channel oil injection lubrication type.
Similar to GE20-ET, GE15-ET and so on are joint bearings, and the suffix is a specific type.
The joint bearings can be divided into GE, GEC, GEG, GEEW, GEK, GEH and other types, different in size and lubrication, and can be found in the sliding bearing classification of the mechanical design manual.
In the narrow sense, the rod end joint bearing should refer to the commonly known fish eye joint.
The fish eye joint is distinguished by the inner and outer filament according to the connection mode: the internal thread series SIG, the external thread series SAG.
The size of the inner and outer wire is the same as the size of the inner diameter of the fish eye, such as the fish eye joint with the joint M12, and the inner diameter of the bearing is also D12.

Joint bearings are widely used in engineering hydraulic cylinder, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries.
Rod end joint bearing vibration of rod end joint bearing damage is very sensitive, such as peeling, indentation, rust, crack and wear are reflected in the rod end joint bearing, vibration measurement so by using vibration measuring device end joint bearing special rod (frequency analyzer etc) can measure the size of the vibration. Through frequency cannot be inferred from abnormal situation. The measured values are different due to the service conditions of the rod end bearing or the location of the sensors. Therefore, we need to analyze and compare the measured values of each machine beforehand and determine the criteria.
The temperature of rod end bearing is generally predicted by the temperature outside the rod end bearing chamber. If the oil hole can directly measure the temperature of the outer ring of the rod end bearing, it is more appropriate. Usually, the temperature of the rod end joint bearing begins to rise slowly with the rod end bearing operation, and reaches a stable state after 1-2 hours. The normal temperature of the rod end joint bearing varies with the heat capacity of the machine, the amount of heat dissipation, the speed and the load. If the lubrication and install suitable, then the rod end joint bearing temperature quick rise, abnormal high temperature occurs, then you must stop, take the necessary preventive measures. The working temperature of the rod end bearing can be monitored at any time by using the thermal sensor, and the alarm can be automatically stopped or stopped when the temperature exceeds the specified value.
