Problems solved by technology
Since it is necessary to disassemble the coupling to completely remove the load of the tested motor without destroying the installation form and working conditions of the motor, load equipment and torque sensor during the test, the bellows coupling or metal film is used. The coupling is difficult to disassemble, the mass of the coupling itself is large, and the moment of inertia is large, which affects the service life of the precision torque sensor, etc.

Embodiment Construction
[0014] Embodiments of the present invention are further described below in conjunction with the accompanying drawings:
[0015] see figure 1 , this embodiment is a set of half couplings, the half couplings are composed of two parts, the upper half coupling 1 and the lower half coupling 2, which are symmetrical up and down, the upper half coupling 1 and the The lower half coupling 2 has a completely symmetrical structure and the same material. It is precision machined with high-quality materials to ensure its machining accuracy, so that it has good dynamic balance performance and is suitable for high-speed applications. The upper half-coupling 1 is a structure of half a shaft sleeve, the top of which is provided with a half flange 8, and the flange 8 is provided with six rope holes 5, and the lower half-coupling 2 is completely same. The upper half-coupling 1 and the lower half-coupling 2 are provided with a spindle hole 3 and a keyway 6, and both sides of the upper half-coup...

The invention relates to a split clamping type coupler, which comprises one group of half couplers, wherein each half coupler consists of a flange disc, rope penetrating holes, a shaft sleeve, positioning bolt holes and a key slot. The coupler is characterized in that each half coupler consists of an upper part and a lower part which are split, each part consists of half of one shaft sleeve, the top end of each part is half of one flange disc, the two sides of each half of each shaft sleeve are respectively provided with two positioning holes which radially penetrate through the wall of the corresponding shaft sleeve, the half couplers penetrate through the positioning holes via bolts and are clamped on an output shaft of a motor, a loading shaft is clamped with the pair of half couplers, the flange discs of the half couplers are provided with a plurality of rope penetrating holes, and the two half couplers are fixedly connected together by a cable rope penetrating through the rope penetrating holes. The coupler has the advantages that the structure is simple and compact, the running is stable, the noise is little, the installation and detachment are convenient, the weight is light, and the rotation inertia is little.
Description
technical field [0001] The invention relates to a shaft coupling, in particular to a bipartite embracing type shaft coupling. Background technique [0002] Coupling is a mechanical device that connects two shafts or shafts and rotating parts, and rotates together without disengaging during the process of transmitting motion and torque. It is an indispensable connecting part in the mechanical transmission shaft system. It has many types, large dosage, and wide application range. It is a general-purpose basic transmission part. [0003] In the motor load test, a precision torque speed sensor needs to be connected between the output shaft extension of the motor and the shaft extension of the load part to measure the output power of the shaft end of the motor under test. In order to ensure the test accuracy, bellows couplings or metal Diaphragm coupling for connection. Since it is necessary to disassemble the coupling to completely remove the load of the tested motor without d...
