Description

Technical Field

[0001] The utility model belongs to the technical field related to couplings, and particularly relates to a drum-shaped gear coupling which is convenient to install. Background Art

[0002] Drum gear coupling is a rigid-flexible coupling with radial, axial and angular axis deviation compensation capabilities. Compared with CL-type spur gear coupling, it has the advantages of compact structure, small turning radius, large load capacity, high transmission efficiency, low noise and long maintenance cycle. Drum gear coupling is usually used in low-speed and heavy-load conditions, such as metallurgy, mining, lifting and transportation industries, and is also suitable for shaft transmission of various types of machinery such as petroleum, chemical industry, general machinery, etc. However, it still has the following disadvantages in actual use:

[0003] When installing the drum gear coupling, it is directly installed through the mounting plate on the coupling, and then installed on the mechanical mechanism of the transmission and driving power through the mounting plate through bolts and nuts. When connecting, it is necessary to align, insert the bolts, and screw on the nuts. During the installation process, many components need to be prepared, and the installation process is not convenient enough;

[0004] During the operation of the drum gear coupling, the coupling runs and directly transmits the vibration of the driving structure to the driven structure, causing the driven structure to vibrate. After the driven structure is subjected to direct vibration of the driving structure for a long time, it is easy to be damaged, affecting the durability of the driven structure.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a drum-shaped gear coupling which is easy to install, comprising an inner gear sleeve, a chimeric component, an outer shaft sleeve, a flexible screw sleeve and a fixing spring. Two chimeric components are arranged in the inner gear sleeve, and the two chimeric components are respectively placed at two ends of the inner wall of the inner gear sleeve. The chimeric component comprises an axis core, and a fixing spring is commonly fixed at one end of the two axis cores which are close to each other, and an outer shaft sleeve is fixed at one end of the two axis cores which are far away from each other. A mounting plate is fixed on the outer circumferential surface of one end of the outer shaft sleeve which is far away from the axis core, and a flexible screw sleeve is fixed in an annular array in the mounting plate. When working, the chimeric component is movably connected therein through the inner gear sleeve, and when the chimeric component rotates, the inner gear sleeve is driven to rotate, and the other chimeric component is driven to rotate to transmit power. The outer shaft sleeve is provided to provide an external transmission shaft which is movably connected therein, and the flexible screw sleeve is provided to provide an installation function of the mounting plate and the mounting structure of the external transmission.

[0008] Furthermore, internal meshing teeth are fixed in a ring array on the inner wall of the inner gear sleeve, and flexible rings are fixed on both ends of the inner gear sleeve. The inner gear sleeve meshes with the external meshing teeth on the outer gear sleeve through the internal meshing teeth.

[0009] Furthermore, the interlocking component also includes an external gear sleeve and external meshing teeth. The external gear sleeve is fixed on the circumferential side of the shaft core, the external gear sleeve is arranged in a drum shape, and the external meshing teeth are fixed in an annular array on the outer surface of the external gear sleeve. The external meshing teeth are meshed with the internal meshing teeth in the internal gear sleeve. The interlocking component is connected to the external meshing teeth through the external gear sleeve, and the external meshing teeth are meshed with the internal meshing teeth in the internal gear sleeve, so that the internal gear sleeve can transmit power.

[0010] Furthermore, a keyway is provided on the inner wall of the outer sleeve, and fixing holes are provided in a circular array in the mounting plate. The outer sleeve is sleeved in the flexible sleeve ring, and the outer sleeve is movably connected to the connecting key on the transmission shaft through the keyway, and the flexible screw sleeve is fixed therein through the fixing hole.

[0011] Furthermore, the flexible screw sleeve is fixed in the fixing hole, and one end of the flexible screw sleeve close to the inner gear sleeve is flush with the end surface of the mounting plate.

During installation, the drum gear coupling does not need extra installation components, and the installation is more convenient.

[0015] The utility model solves the problem that the drum gear coupling has no shock absorbing effect during the transmission process by arranging an inner gear sleeve, an engaging component and a fixed spring.

During the transmission process, the two shaft cores are connected to each other by the fixed spring, so that when the power component is vibrated, the vibration is directly transmitted to the driven equipment, the vibration of the driven equipment is reduced, and the durability of the driven structure is increased.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0025] See also Figure 1-5 The utility model is a drum gear coupling that is easy to install, including an inner gear sleeve 1, a chimeric component 2, an outer shaft sleeve 3, a flexible screw sleeve 4 and a fixed spring 5. Two chimeric components 2 are arranged in the inner gear sleeve 1. The inner gear sleeve 1 accommodates the chimeric component 2 therein. The chimeric component 2 is accommodated in the inner gear sleeve 1 to transmit the rotating power and torque. The two chimeric components 2 are disposed at both ends of the inner wall of the inner gear sleeve 1. The two chimeric components 2 are respectively used to input power to the inner gear sleeve 1 and transmit power output through the inner gear sleeve 1. The chimeric component 2 includes a shaft core 201. The ends of the two shaft cores 201 that are close to each other are commonly fixed with a fixed spring 5. The two shaft cores 201 are connected to each other through the fixed spring 5 to reduce the power When the component is vibrated, the vibration and the driven equipment are directly transmitted through the coupling, reducing the vibration of the driven equipment. The ends of the two shaft cores 201 that are away from each other are fixed with outer sleeves 3. The outer sleeves 3 are used to flexibly connect the transmission shaft that transmits power between the driving equipment and the driven equipment. A mounting disk 302 is fixed on the outer circumferential surface of the end of the outer sleeve 3 away from the shaft core 201. The mounting disk 302 fixes the flexible screw sleeve 4 therein. The mounting disk 302 has flexible screw sleeves 4 fixed in an annular array. When the internal screw 401 of the flexible screw sleeve 4 rotates to drive the fixed disk 403 to rotate, the flexible screw sleeve 4 is compressed. After compression, the mounting disk 302 and the external mounting component are installed together.

[0026] Specifically, internal meshing teeth 101 are fixed in a circular array on the inner wall of the inner gear sleeve 1, and flexible rings 102 are fixed at both ends of the inner gear sleeve 1. The inner gear sleeve 1 is engaged with the outer gear 203 through the internal meshing teeth 101 to transmit the rotational power and torque, and the engaging component 2 is limited by the flexible ring 102, and the outer shaft sleeve 3 is sleeved therein to limit the position of the outer shaft sleeve 3.

[0027] Furthermore, the interlocking component 2 also includes an outer gear sleeve 202 and outer meshing teeth 203. The outer gear sleeve 202 is fixed on the circumferential side of the shaft core 201. The outer gear sleeve 202 is arranged in a drum shape. The outer surface of the outer gear sleeve 202 is fixed with outer meshing teeth 203 in a ring array. The outer meshing teeth 203 are interlocked with the inner meshing teeth 101 in the inner gear sleeve 1. The interlocking component 2 is drum-shaped through the outer gear sleeve 202. With the cooperation of the outer meshing teeth 203, there can be a certain angle between the axis center line of the shaft core 201 and the axis center line of the inner gear sleeve 1, but power can still be transmitted.

[0028] The operation process of this embodiment is as follows: during operation, after the outer shaft sleeve 3 and the flexible screw sleeve 4 are installed with the external transmission shaft, the outer gear sleeve 202 is formed into a drum shape through the interlocking component 2. With the cooperation of the external meshing teeth 203, there can be a certain angle between the axis center line of the shaft core 201 and the axis center line of the inner gear sleeve 1, but the power can still be transmitted. The mounting disk 302 is rotated. When the mounting disk 302 rotates, it drives the outer shaft sleeve 3 to rotate. When the outer shaft sleeve 3 rotates, it drives the shaft core 201 to rotate. The rotation of the shaft core 201 drives the outer gear sleeve 202 to rotate, and drives the external meshing teeth 203 to rotate. The external meshing teeth 203 on the inner gear sleeve 1 are engaged with the internal meshing teeth 101, driving the other interlocking component 2 to rotate for transmission. During the transmission process, the two shaft cores 201 are connected to each other by the fixed spring 5. When the power component is subjected to vibration, the vibration is directly transmitted to the driven equipment, thereby reducing the vibration of the driven equipment. Specific embodiment 2

On the basis of the specific embodiment 1, a keyway 301 is provided on the inner wall of the outer sleeve 3, and a fixing hole 303 is provided in a ring array in the mounting plate 302. The outer sleeve 3 is sleeved in the flexible sleeve ring 102, and the outer sleeve 3 is movably connected with the connecting key on the transmission shaft through the keyway 301, so that the transmission shaft is movably connected therein, and the outer sleeve 3 is sleeved in the flexible sleeve ring 102, and with the cooperation of the engaging component 2, the movable range of the outer sleeve 3 is limited.

[0030] Specifically, the flexible screw sleeve 4 is fixed in the fixing hole 303, and the end of the flexible screw sleeve 4 close to the internal gear sleeve 1 is flush with the end surface of the mounting plate 302. The flexible screw sleeve 4 is threadedly connected with an internal screw 401. The flexible screw sleeve 4 is fixed in the fixing hole 303 and flush with the mounting plate 302 to determine the corresponding equipment position.

[0031] Furthermore, a rotating block 402 is fixed to one end of the inner screw 401 close to the inner gear sleeve 1, and a fixed disk 403 is fixed to one end of the inner screw 401 away from the inner gear sleeve 1. By rotating the rotating block 402, the inner screw 401 is driven to rotate, and the fixed disk 403 is driven to rotate, so that the flexible screw sleeve 4 is squeezed and expanded, and is fastened together with the external mounting structure.

[0032] The operating process of this embodiment is: when working, first align the outer sleeve 3 with the external mounting structure, then insert the transmission shaft into the outer sleeve 3, so that the connecting key on the transmission shaft enters the keyway 301 in the outer sleeve 3, and then continue to insert it, so that the mounting assembly on the transmission shaft is aligned with the flexible screw sleeve 4 on the mounting disk 302, and the flexible screw sleeve 4 is inserted into the mounting assembly, and then the rotating block 402 is rotated to drive the inner screw 401 to rotate, and drive the fixed disk 403 to rotate, so that the flexible screw sleeve 4 is squeezed and expanded, and installed together with the external mounting structure.
