Embodiment Construction

[0014] The present invention will be further described in conjunction with accompanying drawing:

[0015] Referring to the accompanying drawings, a high-precision coaxial coupling mechanism includes a secondary transmission wheel 1, a main transmission wheel shaft 2, a coupling plate 3, a coupling screw 4, a mounting plate 5, a bearing 6, a bearing compression ring 7, and the like. When installing, first install the bearing 6 into the mounting plate 5 by the "hot packing method", press the bearing 6 with the bearing pressing ring 7, and tighten the fastening screws. Put the small end of the main transmission wheel shaft 2 into the 6 holes of the bearing for alignment, and put it on the hand press to press it in place. The hole of the secondary drive wheel 1 is installed on the corresponding position of the corresponding main drive wheel shaft 2. The main transmission wheel shaft 2 and the secondary transmission wheel 1 adopt clearance fit. By controlling the processing accur...

Abstract

The invention relates to a high-precision coaxial coupling mechanism, which comprises a secondary driving wheel (1), a main driving wheel shaft (2), a coupling plate (3) and a coupling screw (4), wherein the bottom surface of the secondary driving wheel (1) is provided with a stop spigot, a first group of screw holes is uniformly distributed on the spigot, a second group of screw holes is uniformly distributed on the main driving wheel shaft (2), the coupling plate (3) is provided with a countersunk screw hole corresponding to the screw hole on the secondary driving wheel (1) and the main driving wheel shaft (2), the secondary driving wheel (1) is in clearance fit with the main driving wheel shaft (2), the coupling plate (3) is arranged inside the spigot of the secondary driving wheel (1) to be just opposite to the screw hole on the matching end surface between the countersunk screw hole and the main driving wheel shaft (2), a group of coupling screws (4) is arranged inside the countersunk screw hole to be tightened, so the bottom surface of the coupling plate (3) is tightened with the end surface of the main driving wheel shaft (3). The thread is deformed and self-locked and is difficult to be threaded off.

Description

technical field [0001] The invention relates to the field of machinery, especially in the field of precision manufacturing. Compared with the traditional key, pin and other connection methods, it can adapt to the alternating torque of forward and reverse rotation, has high coaxial rotation accuracy, high reliability, and no empty backhaul. , high-efficiency torque transmission, and space-saving coaxial coupling mechanism. Background technique [0002] The most traditional and common method for coaxial torque transmission between the wheel and the shaft is through keys, pins, threads, interference fits, etc. However, these connection methods often have deficiencies, such as key or pin connection, which transmits torque by shear force. When carrying forward and reverse alternating torque for a long time, a shear gap will gradually occur, and as the gap increases, the shear gap will Cut the impact more and more until it is damaged. The threaded connection is only suitable for...
