The disadvantages of this structure are: 1. The relative offset of the two shafts in the transmission compensation of the coupling with this structure is small, and the inclination angle of the node is only 0.5°, which requires high transmission accuracy and increases the difficulty of installation; 2. The coupling with this structure is only suitable for Coaxial horizontal shafting installation, vertical installation and suspension operation are not allowed

The invention relates to a coupling for transmitting torque between shafts, particularly to a suspended elastic pin gear type coupling. The suspended elastic pin gear type coupling comprises an input half coupling, an output half coupling and a connecting outer sleeve; the input half coupling is fixedly connected with the front end of the connecting outer sleeve; the head portion of the output half coupling is matched with an inner hole of the connecting outer sleeve in a sleeved mode; involution holes which are formed along the circumference are formed between the head portion of the output half coupling and the matching surface of the connecting outer sleeve; nylon pins are arranged inside the involution holes; the nylon pins are drum-shaped and the diameters of drums are gradually decreased from the middle to the two ends; meanwhile the profile of the outer circumferential surface of the head portion of the output half coupling is arc-shaped on the longitudinal section. The suspended elastic pin gear type coupling has the advantages of enabling the allowed deflection angle between the two half couplings to be increased due to the drum-shaped nylon pins, accordingly reducing the installing difficulty of a transmission shaft and enabling a spherical matching supporting surface to be used for transmission of a vertical suspension shaft due to the spherical matching supporting surface which is formed between an annular end cover and the output half coupling.
Description
technical field [0001] The invention relates to a shaft coupling used for torque transmission between shafts, in particular to a suspended elastic pin gear coupling. Background technique [0002] The national standard GB / T5015-85 discloses an elastic pin gear coupling, the structure of which is to use several cylindrical nylon pins to be placed in the mating holes between the two halves of the coupling and the inner surface of the outer ring. The torque is transmitted through the longitudinal shear strength of the column pin to realize the connection of the two halves of the coupling. The disadvantages of this structure are: 1. The relative offset of the two shafts in the transmission compensation of the coupling with this structure is small, and the inclination angle of the node is only 0.5°, which requires high transmission accuracy and increases the difficulty of installation; 2. The coupling with this structure is only suitable for The coaxial line is installed on the h...
