Problems solved by technology

However, the outer diameter of the half-couplings in domestic and foreign coupling products adopts external lap joints or convex and groove butt joints, and the butt joint gap is large, difficult to assemble and disassemble, and the positioning effect is not good and it is not beautiful.
The gap between the half-couplings of the coupling is adjusted by a thin sheet, which is easy to fall off in case of vibration
The diaphragm group of the coupling adopts a single-layer diaphragm group, which has a short service life
When adjusting the distance between the two half-couplings, a single bolt is used to adjust along the two half-couplings, which requires many bolts, wastes materials, and takes time
The inner hole of the two halves of the coupling and the outer diameter of the shaft are over-fitted. During the over-fitting loading and unloading process, the shaft surface and the inner hole of the half-coupling are often pulled, which is not easy to install and disassemble.
When the motor is started frequently, the two ends of the coupling inevitably vibrate or even deform, which affects the axial, radial and angular offsets caused by the misalignment of the two shafts. Both need to do dynamic balancing treatment to balance the mass imbalance caused by the center to overcome the above-mentioned possible situations, but the structure of this coupling is complicated and the operation process is cumbersome; at the same time, in order to increase the weight and keep the coupling stable, Unavoidable defects in its appearance caused by drilling holes in its body

Embodiment 1

[0022] Such as figure 1 one image 3 As shown, the present invention is not used as a dynamic balance type high-torque elastic coupling including: two half-couplings 1, 2, two docking discs 3, 4, middle section 5, diaphragm group 6, high-strength elastic ring 7, The two half-couplings 1 and 2 are shaft connecting sleeves with connecting flanges at one end, the middle section 5 is a shaft connecting sleeve with flanges at both ends, two docking discs 3 and 4 and two half couplings The shaft joints 1 and 2 are installed at both ends of the middle section 5 through bolts, and the outer surfaces of the two docking discs 3 and 4 are connected with the two half-coupling joints 1 and 2 by means of spigot positioning. The two docking discs 3 and 4 The inner surface of the inner surface is respectively connected with the flanges at both ends of the middle section 5, and the diaphragm group 6 is installed between the two docking plates 3, 4 and the middle section 5. Diaphragm group 6 ...

Embodiment 2

[0025] Such as Figure 5 As shown, on the basis of the coupling in Example 1, when the length of the middle section 5 of the coupling of the present invention is less than 230 mm, the elastic device 14 of the coupling adopts an external connection type, and its two elastic bolts 11 and 12 adopt a 90-degree knuckle and only one end has threaded bolts, and the long nut 13 adopts a hexagonal long nut. And the outer edges of the two docking plates 3,4 are also provided with jacks 15 for installing external elastic devices, and the threadless ends of the two long bolts 11,12 are inserted into the sockets on the outer edges of the two docking plates 3,4 In the hole 15, the threaded end is screwed with the long nut 13.

[0026] When installing and using, first twist the threaded ends of the two long bolts 11, 12 into the long nut 13, and then insert the two ends of the two long bolts 11, 12 without threads into the outer edge of the coupling disc 3, 4 in the jack. Tighten or loose...

Abstract

The invention relates to an actuation balance-free type super large torque flexible coupling with an intermediate section, which comprises two half-couplings, two butting discs and a diaphragm group and has improvements in also comprising the intermediate section, high-strength elastic rings and a tightening device, wherein the two butting discs and the two half-couplings are installed on both ends of the intermediate section through bolts and positioned by bayonets; the diaphragm group is laminated and installed among the butting discs and the intermediate section; the external side surfaces of the butting discs are provided with grooves in which the high-strength elastic rings are installed; the two half-couplings and the intermediate section are respectively provided with a circle of outward bulgy lug bosses; and the tightening device comprises two tightening bolts and a long nut, wherein one end of each tightening bolt is connected with each butting disc and the other end is screwed into the long nut. The actuation balance-free type super large torque flexible coupling with the intermediate section has the advantages of large power transfer torque, longer service life, wider configuration range and simple loading and unloading, thereby being suitable for fields of petroleum, chemical engineering, metallurgy, machinery, environmental protection, mining, shipping, aerospace, diversion engineering, nuclear power, military affairs, and the like.

Description

Technical field: [0001] The invention relates to a shaft coupling, in particular to an elastic shaft coupling with an intermediate section of super large torque which is not used for dynamic balance. Background technique: [0002] As the motor transmits power, the most common one is to connect the output shaft of the motor with the transmission shaft through a coupling, so that the power of the motor can be transmitted. However, the outer diameter of the half-couplings in domestic and foreign coupling products adopts external lap joints or convex and groove butt joints, and the butt joint gap is large, difficult to assemble and disassemble, and the positioning effect is not good and it is not beautiful. The gap between the half-couplings of the coupling is adjusted by a thin sheet, which is easy to fall off in case of vibration. The diaphragm group of the coupling adopts a single-layer diaphragm group, which has a short service life. When adjusting the distance between the...
