Generally, a torsion angle limiter shall be installed, and it may not be installed under special circumstances. During the use of the Flexible Coupling transmission parts, the relative offset of the two shafts connected shall not be greater than the specified allowable compensation amount. During the static torsion test of the ring, it was found that the rubber of the rubber elastic ring should not crack or break off under the instantaneous large torque. The Flexible Coupling can compensate the axis displacement and elasticity, but the allowable compensation amount of the axis displacement is small, and it has the performance of compensating the relative deviation of two shafts. It is suitable for medium and large power transmission, and is not suitable for the working parts that require vibration reduction and noise control.
During the manufacturing process of the Flexible Coupling, several screws are used for connection, and the nut end of the screws used need elastic washers. A hole of the same size is drilled in the half section, which is inserted with a nylon rod, and the outside is covered with a baffle. The two half couplings are connected with nylon rods, which can play the role of compensation. Its cross section has fractures, which damage the chemical composition and structural uniformity of the steel, reduce the quenching hardness, and deteriorate the mechanical properties. The pin in the shaft of the Flexible Coupling is in the shear and extrusion state when working, and the cross section has the shear strength and the extrusion strength between the pin and the pin hole wall.
The structure of the pouring system shall be as simple as possible, and the section size shall be larger than that of the cast iron. The dry or hot casting mode shall be adopted, and the pouring temperature shall be appropriately increased, because the pouring temperature is high, the superheat of the molten steel is large, and the liquid state shall be kept for a long time. The mechanical properties of forgings are generally better than those of castings of the same material. Forging is a common forming method in mechanical manufacturing. Through forging, the casting porosity and welding holes of metal can be eliminated. Flexible Couplings are widely used in various important structural parts, especially those working under alternating load, but the surface hardness is low. Surface hardening improves the surface hardness of parts.
