[0022] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0023] See also Figures 1-4 The utility model provides a carburized and ground gear drum transmission device, including a drum gear coupling body, the drum gear coupling body including a pair of coupling sleeves 1, each coupling sleeve 1 is provided with a coupling sleeve 2 on a movable sleeve, and the pair of coupling sleeves 2 are connected by a flange 3. In this application, the drum gear coupling body may also include an inner gear ring arranged in the coupling sleeve 2 and an outer gear sleeve adapted to the inner gear ring, etc. Since the structures not involved belong to the existing technology of the drum gear coupling body, they will not be further described here.
[0024] In this embodiment, an extension rod 4 is slidably connected to the flange 3 , and a secondary shaft sleeve 5 is provided at one end of the extension rod 4 .
[0025] The extension rod 4 can provide mobile support for the secondary shaft sleeve 5. By sliding the extension rod 4 through the flange 3, the secondary shaft sleeve 5 can move axially at one end of one of the coupling shaft sleeves 1, thereby adjusting the input or output clearance of the coupling shaft sleeve 1 shaft transmission.
[0026] It is worth noting that in this application, the secondary sleeve 5 can be set at one end of one of the coupling sleeves 1 to adjust the transmission spacing of the coupling sleeve 1 at the input or output end, so that it can be applicable to the connection spacing of various mechanical shaft transmissions.
[0027] In this embodiment, both sides of the extension rod 4 are fixedly connected with reinforcing ribs 7 , and the flange 3 is provided with sliding grooves for the reinforcing ribs 7 and the extension rod 4 to slide.
[0028] The reinforcing ribs 7 can increase the structural strength of the extension rod 4. When the drum gear coupling body rotates, that is, when the secondary sleeve 5 and the shaft system are mechanically transmitted, the technical problem of deformation of the extension rod 4 due to force can be avoided, thereby improving the durability of the extension rod 4.
[0029] In this embodiment, there are multiple extension rods 4 , and the multiple extension rods 4 are detachably connected with support ring plates 8 .
[0030] In the present application, the support ring plate 8 is an annular structure, and multiple extension rods 4 can be connected to the support ring plate 8 with existing fasteners, such as bolt structures. On the one hand, the support ring plate 8 can strengthen the connection strength of the end side positions of the multiple extension rods 4. On the other hand, the support ring plate 8 can easily release the limitation of the end of the extension rod 4, so that the secondary shaft sleeve 5 can be quickly pulled away from the drum gear coupling body together with the extension rod 4. In this way, the structure with the extended shaft transmission spacing can meet the convenience of disassembly and assembly based on the drum gear coupling body.
[0031] In this embodiment, the secondary shaft sleeve 5 and the coupling shaft sleeve 1 are coaxially arranged.
[0032] The auxiliary sleeve 5 can move linearly along the axial direction of the coupling sleeve 1, which can conveniently expand the input or output distance of the coupling sleeve 1. Then, the auxiliary sleeve 5 has the transmission function of the drum gear coupling body to the shaft system transmission. The auxiliary sleeve 5 can provide the drum gear coupling body with the technical effect of adjustable shaft system transmission spacing. The two complement each other and are more practical.
[0033] In this embodiment: the outer surface of the secondary shaft sleeve 5 is fixedly connected with a fixing plate 9, the number of the fixing plates 9 is the same as the number of the extension rods 4, one end of the extension rod 4 is fixedly connected to the fixing plate 9, and one end of the reinforcing rib plate 7 is also fixedly connected to the fixing plate 9.
[0034] The fixing plate 9 can be made of the same material as the reinforcing rib plate 7. While ensuring the structural strength, the fixing plate 9 can facilitate the connection between the secondary shaft sleeve 5 and the extension rod 4. Since one end of the reinforcing rib plate 7 is also fixedly connected to the fixing plate 9, and since the extension rod 4 will involve slots, the reinforcing rib plate 7 can compensate for the structural strength of the extension rod 4 reduced by the slots. At the same time, the reinforcing rib plate 7 can further improve the connection strength between the fixing plate 9 and the extension rod 4.
[0035] In this embodiment: a locking assembly 6 is provided on the extension rod 4 and one of the coupling sleeves 1, the locking assembly 6 includes a locking bolt 61, the locking bolt 61 is threadedly connected to the extension rod 4, and the outer surface of the coupling sleeve 1 is fixedly connected to a positioning seat 62 for threaded connection of the locking bolt 61.
[0036] During use, after the adjustment of the distance between the secondary sleeve 5 and the coupling sleeve 1 is completed, the locking bolt 61 can be threadedly connected to the extension rod 4 and the positioning seat 62 in sequence. Since the locking assembly 6 is matched with the number of extension rods 4, the locking bolt 61 can strengthen the connection between the extension rod 4 and the coupling sleeve 1, thereby stabilizing the stability of the secondary sleeve 5 to the shaft transmission connection.
[0037] In this embodiment, a plurality of thread grooves 41 are formed on the extension rod 4 , and the plurality of thread grooves 41 are arranged along the length direction of the extension rod 4 , and the locking bolt 61 is threadedly connected to one of the thread grooves 41 .
[0038] Because the secondary shaft sleeve 5 needs to adapt to the requirements of the transmission connection spacing of various mechanical shaft systems, the locking assembly 6 needs to adapt to the movement of the extension rod 4 for fixation. Therefore, by setting multiple threaded grooves 41, the locking bolt 61 is provided with multiple fixed position connection requirements, so that the locking assembly 6 can be adapted to the fixing requirements of the secondary shaft sleeve 5 at different axial positions.
[0039] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
