GK-DO Rod Ends

GK-DO Rod Ends
Rod ends bearing is a spherical sliding bearing, which is composed of an inner ring with a spherical sliding sphere contact surface, an inner ring with an inner sphere and an outer ring with an inner sphere, and can bear a large load.According to its different types and structures, it can bear the radial load, the axial load or the combined load in the radial direction.Generally used for low speed swing motion, but also in a certain Angle range for tilt motion, when the supporting shaft and shaft shell hole is not concentricity is large, still can work normally.Self-lubricating joint auxiliary bearing should be used in water conservancy, professional machinery and other industries.

GK-DO Rod Ends Features

Rod ends bearing ring fracture is one of the problems troubling the quality of bearings, and defect fracture is the main form of bearing ring fracture, which is mainly caused by the problems of raw materials themselves or improper production operation, equipment can not operate normally.Inclusion of raw materials, loose, brittle element segregation or carbides liquid chromatography, mesh, ribbon, not spared homogenization and other defects in the processing process is not eliminated or improved, become the source of cracks.In the forging process, if over-burning, over-heat, internal crack into a network of carbides and so on will reduce the toughness and strength of the ring.So must always be strictly control the processing temperature, cyclic heating and cooling after forging, etc., especially in large breed ring after finish forging, the temperature is above 700 ℃, the shall not be piled up to put.The instrument, thermocouple and other important thermostat must be closely monitored to ensure that the measurement data is accurate and reliable, monitoring data records, must restore the temperature of the heat treatment equipment recording device, in order to effectively monitor the whole process of equipment work, so that the quality of heat treatment has a strong traceability, put an end to false records and randomness.Quenching cooling conditions, in order to solve the medium and large varieties of bearing rings soft spots and other defects, improve the quenching cooling conditions.Aiming at the varieties with more fracture phenomena, secondary tempering is carried out after rough grinding of the rings, which can not only further stabilize the structure and size of the rings, but also reduce the grinding stress and improve the performance of grinding metamorphic layers.The finished bearing rings are not allowed to have grinding burns and grinding cracks. If the rings are pickling, they should be fully inspected to remove the burned products. The rings with grinding burns are not allowed to enter the assembly process.
