Coupling information:
1. A rubber cylindrical pin elastic coupling, which comprises a main and driven half coupling, is characterized in that: the inner hole of the driving half coupling 4 is connected with the driving shaft, and its large outer diameter part is inserted into the shaft. In the large inner hole of the driven half-coupling 1, the small inner hole of the driven half-coupling 1 is connected with the driven shaft, and the large inner hole is sleeved on the large outer diameter of the driving half-coupling 4. The parts of the 4-phase sleeves are not in direct contact with each other, leaving a radial gap of 0.3-1.5mm on one side and an axial gap of 1mm. The inner hole of the half-coupling has semi-circular holes evenly distributed on the circumference of the same indexing circle diameter. The number can be selected between 4 and 12, and the axis of the semi-circular hole is parallel to the axis of rotation of the coupling. When the main and driven semi-couplings are assembled on the two shafts of the same axis, these semi-circular holes are assembled together. 4 to 12 cylindrical holes, the intermediate medium for transmitting torque and motion, connecting the main and driven half-couplings - the rubber cylindrical pin 2 is installed in the cylindrical holes formed by these semi-circular holes. On the end face, there are four screw holes and four hexagon socket head cap screws 5, which press the two half-circle baffles 3 on the end face of the driven half-coupling.
