Abstract

The invention provides a split coupling which comprises a first clamp shell and a second clamp shell which are separated along the axial direction and mutually fastened, and bolts. The first clamp shell is provided with four first through holes. The second clamp shell is provided with four second through holes. The first through holes and the second through are continuously communicated. The bolts penetrate through the first through holes and the second through holes continuously to fasten the first clamp shell with the second clamp shell. Two semicircular grooves mutually fastened are reserved on the inner wall faces of the first clam shell and the second clamp shell respectively so as to form a continuous circular groove. A spring component is embedded in the annular groove and comprises a spring and gaskets disposed at two ends of the spring. The spring component is disposed in the circular groove along the lengthwise extending direction of the split coupling. Axial vibration between a drive shaft and a driven shaft is reduced, service life of the split coupling is prolonged, and service life of a rotational molding device is also prolonged.
