Coupler facilitating limitation of adjustable range

Abstract

The invention discloses a coupler facilitating limitation of an adjustable range. The coupler comprises a main coupler body, a connecting block, a center plate, a cylindrical pin and a reset spring, and the connecting block is clamped on the outer surface of the main coupler body; the center plate and a secondary coupler body are fixedly installed on the outer surface of the connecting block; anda limiting groove is formed in the outer surface of the secondary coupler body, and a sliding groove is formed in the inner surface of the connecting block. According to the coupler facilitating limitation of the adjustable range, an adjustable shaft body locking ring is arranged, and is easy to install in the coupler through a buckle installed on the outer surface of the shaft body locking ring,and both the inner surface of the shaft body locking ring and the inner surface of the coupler are provided with built-in grooves; movable blocks can be installed on the inner surfaces of the built-ingrooves slidably, and locating blocks with locking functions are fixedly installed on the outer surfaces of the movable blocks; and meanwhile, the outer surfaces of the locating blocks are provided with circular protruding structures facilitating extrusion, locking and fixation of the shaft body.

Description

technical field [0001] The invention relates to the technical field of shaft couplings, in particular to a shaft coupling for conveniently limiting an adjustable range. Background technique [0002] With the current development of science and technology, the industry has begun to use couplings to connect two shafts (drive shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque mechanical parts. In high-speed and heavy-duty power transmission Among them, some couplings also have the function of buffering, damping and improving the dynamic performance of the shaft system. The coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft. However, during the use of some couplings, sometimes a coupling made of one material cannot meet the conditions of use, including the fact that there is a centrifugal difference between the main shaft and the secondary shaft during use. It is necessary ...

[0002] With the current development of science and technology, the industry has begun to use couplings to connect two shafts (drive shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque mechanical parts. In high-speed and heavy-duty power transmission Among them, some couplings also have the function of buffering, damping and improving the dynamic performance of the shaft system. The coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft. However, during the use of some couplings, sometimes a coupling made of one material cannot meet the conditions of use, including the fact that there is a centrifugal difference between the main shaft and the secondary shaft during use. It is necessary to use a coupling that can produce centrifugal difference, but because this coupling cannot ensure that the centrifugal difference between the main shaft and the secondary shaft is within a certain range during use, it is easy to cause damage to the secondary shaft, and in the During the installation process, due to the contact between the coupling and the shaft body for installation, and the need to repeatedly adjust the position of the device during installation, it is very inconvenient during installation, and it is relatively easy to cause damage to the shaft body
