First, check visually to confirm whether the coupling has signs of wear or fatigue, and then clean the coupling; then, if the coupling needs lubrication, check and replace the lubricating oil. Most couplings only need to be replaced once a year lubricating oil. ...
Slider couplings and sandwich couplings are suitable for the connection of shafts with low speed and large torque. They are two types of couplings that are widely used in building materials machinery. These two types of couplings have their own characteristics. .
The clamping shell coupling uses a pair of clamping shells split along the axial direction, which is clamped by bolts to realize the connection of the two shafts. The torque is transmitted by the friction between the inner surfaces of the two halves of the coupling. A kind of transmission component.Due to its simple structure, the clamp housing coupling...
Metal can improve its structure and mechanical properties after forging.After the casting structure is deformed by hot working by the forging method, due to the deformation and recrystallization of the metal, the original coarse dendrites and columnar grains become equiaxed recrystallized with finer grains and uniform size...
The hardness of the 45# steel quenched and tempered parts after quenching should reach HRC56~59. The possibility of a large cross section is lower, but it cannot be lower than HRC48. Otherwise, it means that the workpiece has not been completely quenched, and there may be sorbite or even ferrite in the structure. Body organization, this kind of organization through tempering, still...
