Description

Taper Lock Rigid Coupling The utility model belongs to a rigid coupling, in which two half couplings with flanges are respectively connected with two shafts by common flat keys, and then the two half couplings are connected into one by bolts to transmit movement and torque. This kind of coupling has two main structural forms: ① by reaming holes and using bolts to realize the two shaft alignment and by bearing extrusion and shear of bolt rod to transfer torque; ② by matching the shoulder on one half coupling with the groove on the other half coupling and centering. The bolts connecting the two half couplings can be ordinary bolts of class A and class B, and the torque is transmitted by the friction moment of the joint surface of the two half couplings. The flange coupling can be made of gray cast iron or carbon steel, and cast steel or forged steel shall be used under heavy load or when the peripheral speed is greater than 30 m / s. According to the transmission torque, all bolts on the flange can be reamed, or half of them can be reamed, and the other half can be ordinary bolts. Flange coupling before change: the included parts include half coupling (material HT200, zg270-500, 35), bolt (performance level 4.8, 8.8) non-metallic lock nut (performance level 5, 8)
