Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. If the words "up", "down", "left" and "right" appear in the following, it only means that they are consistent with the directions of up, down, left and right in the drawings themselves, and do not limit the structure.

[0022] As shown in 1 and 2, a rigid coupling with high service life includes two disk-shaped half-couplings A1 and half-coupling B6, which are fixedly connected to the half-coupling A1 and face outwards. The fixed shaft cylinder A8 at the center of the side, and th...

Abstract

The invention discloses a rigid coupling with long service life and belongs to the field of mechanical transmission. A fixed shaft barrel pair correspondingly arranged on the outward sides of half couplings are fixed by corresponding connecting pieces, buffer devices are arranged between the two half couplings, and when one half coupling is driven by the fixed connecting piece to rotate, a shaft rod connected with one coupling can be driven to rotate around the center of the half coupling, and then a piston rod is pushed to move relative to a hydraulic barrel, so that a piston moves in the hydraulic barrel; and due to the fact that the movement of the piston is hindered by reverse elastic force of springs and viscous force of hydraulic oil in the hydraulic barrel at the same time, instantaneous large loads are buffered and absorbed, so that loads borne by the other half coupling and the connecting piece connected with the half coupling are lowered, and the overload protection effect isachieved. Compared with a traditional manner of connection with a single key, by adopting the rigid coupling with long service life, an instantaneous torque can be elastically buffered and absorbed;and all components in the device do not rigidly collide with each other, so that the service life of the whole device is prolonged.

Description

technical field [0001] The invention belongs to the field of mechanical transmission, and in particular relates to a rigid shaft coupling with high service life. Background technique [0002] Rigid couplings are used to transmit large torques while preventing the connected parts from bearing excessive loads, and play the role of overload protection. They are generally used in shaft transmissions with stable loads, high speeds, or high transmission accuracy requirements; the most representative of them The most famous is the flange coupling, also known as the flange coupling, which uses bolts to connect two flange flange half couplings, and the two half couplings are respectively connected to the two shafts with keys to realize the two shafts. , to transmit torque and motion. Among them, the key bears most of the load, and the mutual extrusion and collision between the key and the keyway for a long time will easily cause a gap between the two, thereby reducing the service li...
