Combined coupler

Abstract

The invention discloses a combined coupler which comprises two shaft seats, wherein the two shaft seats are connected with each other. The opposite faces of the two shaft seats are provided with a first installation ring and a second installation ring correspondingly, the inner wall of the first installation ring is provided with a first check ring, and the outer wall of the check ring, the inner wall of the first installation ring and the side walls of the corresponding shaft seat form an installation slot. The upper inner wall and the lower inner wall of the installation slot are both provided with a plurality of first nut holes. The inner wall of the first installation ring is provided with an inner thread, the outer wall of the second installation ring is provided with an outer thread, and the second installation ring is provided with a plurality of second nut holes. By means of the manner, the combined coupler is simple in structure, rapid in connection and firm in connection, therefore friction is lowered, and noise is lowered.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a combined shaft coupling. Background technique [0002] Couplings are widely used in mechanical, hydraulic and other transmission fields. They are mainly used for the connection between shafts. Generally speaking, due to reasons such as processing machine tools and manufacturing costs, the manufacturing size of the shaft should not be too long. Therefore, the transmission rotation In the process of movement, sometimes at least 2 shafts are needed. The coupling is used to connect the shafts and has a good performance of transmitting rotational motion. The coupling is used to connect two shafts in different mechanisms (the driving shaft and the driven shaft) to make it rotate together to transmit the mechanical parts of the torque. In the high-speed and heavy-duty power transmission, some couplings also have the function of buffering, damping and improving the dynamic performan...

[0002] Couplings are widely used in mechanical, hydraulic and other transmission fields. They are mainly used for the connection between shafts. Generally speaking, due to reasons such as processing machine tools and manufacturing costs, the manufacturing size of the shaft should not be too long. Therefore, the transmission rotation In the process of movement, sometimes at least 2 shafts are needed. The coupling is used to connect the shafts and has a good performance of transmitting rotational motion. The coupling is used to connect two shafts in different mechanisms (the driving shaft and the driven shaft) to make it rotate together to transmit the mechanical parts of the torque. In the high-speed and heavy-duty power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of the shaft system, but in the process of transmitting torque Among them, the contact connection between the two halves of the coupling will generate greater friction, which will cause wear to the structure of the two halves. At the same time, because the coupling is a metal structure, it will usually generate a lot of noise during friction
