Description

Technical Field

[0001] This utility model belongs to the field of mechanical transmission technology, specifically relating to a flexible spline sleeve coupling. Background Technology

[0002] In existing technology, couplings are a widely used power transmission device. Splined couplings can improve the transmitted torque compared to single-key couplings. In practical applications, splined sleeve couplings are rigid couplings, which are inconvenient to disassemble and assemble; they lack axial, radial, and angular compensation capabilities, and produce relatively high noise during operation. For the inclined feeding components of dry granulation mills, the gap between the feeding screw and the pressure roller needs to be adjusted according to the working conditions, and splined sleeve couplings cannot meet the requirements. Choosing other flexible couplings cannot satisfy the ease of disassembly and assembly of the inclined feeding components, which splined sleeve couplings lack. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flexible spline sleeve coupling, which solves the defect that the spline sleeve coupling does not have radial and angular compensation capabilities, and at the same time reduces the noise during the use of the spline sleeve coupling.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: It includes a transmission input component, a transmission output component, and a flexible spline sleeve. The transmission input component engages with an input shaft via a shaft hole and a keyway, and is then secured with a flat washer and screws to form the transmission input component. The transmission output component engages with an output shaft via a shaft hole and a keyway, and is then secured with a flat washer and screws to form the transmission output component. An input shaft spline sleeve is fitted onto the input shaft, and an output shaft spline sleeve is fitted onto the output shaft. The flexible spline sleeve has a hollow cylindrical structure, and the transmission output component is inserted into the flexible spline sleeve from the other end.

[0005] Preferably, the input shaft body is in the shape of a round rod, and 12 rectangular teeth are evenly spaced on the outer surface of one end.

[0006] Preferably, the spline sleeve is made of a flexible material, which is made of one of neoprene rubber and polyurethane.

[0007] Preferably, the keyway of the input shaft spline sleeve is an assembly groove structure formed on the hollow inner sidewall of the spline sleeve body, and the position of the keyway is adapted to the position and number of teeth on the rectangular spline.

[0008] Preferably, the keyway of the output shaft spline sleeve is an assembly groove structure formed on the hollow inner sidewall of the spline sleeve body, and the position of the keyway is adapted to the position and number of teeth on the rectangular spline.

[0009] Preferably, the internal dimensions of the input shaft spline sleeve are the same as those of the input shaft, and the internal dimensions of the output shaft spline sleeve are the same as those of the output shaft.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This invention replaces the original rigid material of the spline sleeve coupling with a flexible material, which not only preserves the simplicity of disassembly and assembly of the spline coupling, but also gives it radial and angular compensation capabilities. At the same time, it reduces the coaxiality requirements of the input and output ends of the coupling, reduces the difficulty of processing and assembly, and can also reduce the noise during the use of the spline sleeve coupling.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] This utility model provides, for example Figure 1-2 The flexible spline sleeve coupling shown includes a transmission input component, a transmission output component, and a flexible spline sleeve (1). The transmission input component is characterized in that: the transmission input component is engaged with the input shaft (5) through its shaft hole and flat keyway, and is then fastened with flat washers and screws to form the transmission input component; the transmission output component is engaged with the output shaft (4) through its shaft hole and flat keyway, and is then fastened with flat washers and screws to form the transmission output component; the input shaft (5) is fitted with an input shaft spline sleeve (2), the output shaft (4) is fitted with an output shaft spline sleeve (3), the flexible spline sleeve (1) is a hollow cylindrical structure, and the transmission output component is inserted into the flexible spline sleeve (1) from the other end.

[0018] The input shaft (5) is a cylindrical rod with 12 rectangular teeth (6) evenly spaced on the outer surface of one end.

[0019] The spline sleeve (1) is made of a flexible material, which is made of either neoprene or polyurethane.

[0020] The keyway of the input shaft spline sleeve (2) is an assembly groove structure opened on the hollow inner side wall of the spline sleeve body. The position of the keyway is adapted to the position and number of teeth on the rectangular spline.

[0021] The keyway of the output shaft spline sleeve (3) is an assembly groove structure opened on the hollow inner side wall of the spline sleeve body. The position of the keyway is adapted to the position and number of teeth on the rectangular spline.

[0022] The internal dimensions of the input shaft spline sleeve (2) are the same as those of the input shaft (5), and the internal dimensions of the output shaft spline sleeve (3) are the same as those of the output shaft.

[0023] Working principle:

[0024] In this embodiment, during the specific assembly of the flexible spline sleeve coupling, the input shaft (5) with the input shaft spline sleeve (2) is inserted onto the output shaft (4), so that the teeth on the input shaft (5) are adjusted to the angle corresponding to the keyway of the output shaft (4). The assembly is completed when the teeth of the input shaft (5) are inserted into the keyway inside the hollow flexible spline sleeve (1).

[0025] In this embodiment, the flexible spline sleeve coupling structure is used in practice because the input shaft (5) and output shaft (4) are equipped with input shaft spline sleeves (2) and output shaft spline sleeves (3), and a flexible spline sleeve (1) is assembled on the periphery. The flexible spline sleeve (1) is made of flexible material and can generate a certain deformation, giving it axial, radial, and angular compensation performance. In addition, during the operation of the flexible spline sleeve coupling, the impact change of the load can be absorbed by the deformation of the flexible spline sleeve (1), thereby protecting the rigid coupling. Moreover, since the flexible spline sleeve coupling is wrapped by the flexible spline sleeve (1), the noise is lower during use.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
