Description

Technical Field

[0001] This utility model relates to the field of coupling technology, and in particular to a flange coupling. Background Technology

[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during the transmission of motion and power. It also serves to prevent the connected components from bearing excessive loads during use, thus providing overload protection.

[0003] The existing couplings and their problems are as follows:

[0004] 1. Center-fastened flange coupling: Two flanged half-couplings are fastened together by bolts at the center of the shaft, and the hub is clamped by two flanges on both sides; it is connected to the motor's D-type output shaft by fastening screws; the fastening screws are connected to the motor's D-type output shaft by set screws, and the friction generated by the set screws prevents the output shaft from coming off, but there is a risk of loosening during long-term operation; at the same time, the torque transmission between the two half-couplings relies solely on the coaxial fastening screws, and the maximum torque that can be transmitted is limited.

[0005] 2. Hexagonal coupling: It transmits torque by matching the hexagonal outer edge with the internal hexagonal hole of the hub; it is connected to the motor's D-type output shaft by a set screw, and the friction generated by the set screw prevents the output shaft from coming off. However, there is a risk of loosening during long-term operation.

[0006] 3. Clamping type coupling: The output shaft is fastened by screws on the side of the linkage shaft, and the friction after fastening prevents the two sides from separating; the structure is complex, difficult to process, and large in size.

[0007] 4. Rigid flange coupling: The two shafts are aligned by bolts through reamed holes; it is connected to the motor's D-type output shaft by fastening screws with set screws. The friction generated by the set screws prevents the output shaft from coming off, but there is a risk of loosening during long-term operation.

[0008] 5. Claw coupling: There is toothed meshing between the two half couplings; the structure is complex and the length of the coupling is increased, resulting in a longer shear force arm perpendicular to the axial direction.

[0009] In summary, existing couplings, after being connected to rotating parts, tend to loosen over time, making them unable to effectively transmit torque. Utility Model Content

[0010] The purpose of this utility model is to provide a flange coupling that can solve the above-mentioned technical problems;

[0011] This utility model provides a flange coupling, comprising:

[0012] In the connected state, one end of the first connector is inserted into the rotating component, and the second connector is connected to one end of the first connector; the other end of the first connector is connected to the driving component.

[0013] The first connecting body is provided with a first limiting plate, and the first limiting plate is provided with a plurality of first limiting parts; the second connecting body is provided with a second limiting plate, and the second limiting plate is provided with a plurality of second limiting parts; the first limiting parts and the second limiting parts are adapted to a plurality of first fixing parts passing through the rotating part.

[0014] As a further technical solution, a fixing plate is provided at the other end of the first connector, and a connecting shaft is provided between the fixing plate and the first limiting plate.

[0015] As a further technical solution, the fixing plate is provided with several fixing holes, and the second fixing member passes through the fixing holes and connects to the driving member.

[0016] As a further technical solution, the first limiting plate is provided with a number of mounting holes, which correspond to a number of fixing holes.

[0017] As a further technical solution, the first connector is provided with a number of mounting slots, which correspond to a number of mounting holes.

[0018] As a further technical solution, it also includes: a center hole, which is formed on the fixing plate.

[0019] As a further technical solution, a boss is provided on the second limiting plate; in the connected state, the boss is placed inside the rotating part.

[0020] As a further technical solution, a first connecting hole is provided at one end of the first connecting body, and a second connecting hole is provided on the second connecting body that penetrates the second limiting plate and the boss; in the connected state, the third fixing member passes through the second connecting hole and connects with the first connecting hole.

[0021] As a further technical solution, a countersunk hole is provided on the second connector.

[0022] As a further technical solution, the first limiting part is a first opening; the second limiting part is a second opening.

[0023] The technical solution of this utility model uses a first connector and a second connector to fix the rotating component, and connects the first connector to the driving component. In use, the driving component drives the first connector to rotate, and under the constraint of the first connector and the second connector, drives the rotating component to rotate. Since the first limiting plate on the first connector and the second limiting plate on the second connector simultaneously limit the first fixing component on the rotating component, the first limiting plate and the second limiting plate can increase the fixing strength of the rotating component when the rotating component rotates, thereby effectively transmitting torque while preventing the rotating component from loosening. At the same time, the first limiting plate and the second limiting plate are engaged with several first fixing components, which can effectively prevent the first limiting plate or the second limiting plate from slipping during rotation.

[0035] like Figure 1-5 As shown, the flange coupling proposed in this utility model includes:

[0036] In the connected state, one end of the first connecting body 100 passes through the rotating member 400, and the second connecting body 200 is connected to one end of the first connecting body 100; the other end of the first connecting body 100 is connected to the driving member 500. The first connecting body 100 is provided with a first limiting plate 101, which has a plurality of first limiting parts 102. The second connecting body 200 is provided with a second limiting plate 201, which has a plurality of second limiting parts 202. The first limiting parts 102 and the second limiting parts 202... The rotating component 400 is adapted to several first fixing members that are mounted on it. Specifically, the first connecting body 100 is rotated under the drive of the drive member 500, and the rotating component 400 is rotated in cooperation with the first connecting body 100 and the second connecting body 200. During the rotation, the rotating component 400 is engaged with several first fixing members through several first limiting parts 102 on the first limiting plate 101 and several second limiting parts 202 on the second limiting plate 201 to prevent loosening during the rotation of the rotating component 400. Preferably, the rotating component 400 is a hub and the drive member 500 is a motor.

[0037] Preferably, the first fixing member is a bolt; the number of the first fixing members can vary depending on different needs, such as two, three or five; in this utility model, four first fixing members are preferably provided; at the same time, in order to limit the first fixing members, four first limiting parts 102 and four second limiting parts 202 are preferably provided, and the first limiting parts 102 and the second limiting parts 202 are engaged with the first fixing members; at the same time, under the action of the first fixing members, the fixing between the first limiting plate 101, the second limiting plate 201 and the rotating part 400 is realized.

[0038] The technical solution of this utility model uses a first connecting body 100 and a second connecting body 200 to fix the rotating component 400, and connects the first connecting body 100 to the driving component 500. In use, the driving component 500 drives the first connecting body 100 to rotate, and drives the rotating component 400 to rotate under the restriction of the first connecting body 100 and the second connecting body 200. Since the first limiting plate 101 on the first connecting body 100 and the second limiting plate 201 on the second connecting body 200 simultaneously limit the first fixing component on the rotating component 400, the first limiting plate 101 and the second limiting plate 201 can increase the fixing strength of the rotating component 400 when the rotating component 400 rotates, thereby effectively transmitting torque while preventing the rotating component 400 from loosening. At the same time, by engaging the first limiting plate 101 and the second limiting plate 201 with several first fixing components, the slippage of the first limiting plate 101 or the second limiting plate 201 during rotation can be effectively avoided.

[0039] like Figure 1 As shown, a fixing plate 103 is provided at the other end of the first connecting body 100, and a connecting shaft 104 is provided between the fixing plate 103 and the first limiting plate 101. In this utility model, the first connecting body 100 is integrally formed, which can ensure the fixing strength of the first connecting body 100. The length of the connecting shaft 104 can be adjusted according to actual use needs to meet the needs of different rotating parts 400 and driving parts 500. In actual connection, the driving part 500 is connected through the fixing plate 103. Specifically, the fixing plate 103 is provided with a plurality of fixing holes 105, and the second fixing member passes through the fixing holes 105 and is connected to the driving part 500. The preferred second fixing member is a bolt.

[0040] In addition, the drive component 500 is provided with a flange, and the flange is provided with several threaded holes. When the fixing plate 103 is connected to the drive component 500, the second fixing member is inserted through the flange after the fixing plate 103 is attached to the flange. Of course, the fixing plate 103 and the flange can be connected by bolts and nuts. Alternatively, the fixing plate 103 and the flange can be connected directly by connecting the bolts to the threaded holes on the flange. The number of fixing holes 105 is the same as the number of threaded holes. The number can be increased or decreased according to actual use requirements. This utility model will not explain this further.

[0041] like Figure 1 and Figure 3 As shown, since the size of the first limiting plate 101 is larger than the size of the fixing plate 103, the fixing plate 103 cannot be installed if the first limiting plate 101 is installed first. Therefore, to better install the fixing plate 103, it is preferable to provide a plurality of mounting holes 106 on the first limiting plate 101, with the plurality of mounting holes 106 corresponding to a plurality of fixing holes 105. In this way, when installing the fixing plate 103 and the flange, tools such as electric screwdrivers can be placed in the mounting holes 106 to tighten the second fastener. Of course, a plurality of mounting grooves 107 are provided on the first connecting body 100, with the plurality of mounting grooves 107 corresponding to a plurality of mounting holes 106. In this way, when disassembling and assembling the second fastener with tools such as electric screwdrivers, the second fastener can be operated more effectively, avoiding the first connecting body 100 from affecting the placement of the tools such as electric screwdrivers in the mounting holes 106. It should be noted that the dimensions of the first limiting plate 101 and the fixing plate can be adjusted according to the changes in the dimensions of the rotating part 400 and the driving part 500, which will not be further explained.

[0042] In addition, the flange is fixed to the drive component 500 by screws. After the flange is installed, the screw heads will protrude from the flange. Therefore, in this utility model, a center hole 300 is provided, which is opened on the fixing plate 103. In this way, after the fixing plate 103 and the flange are installed, the screw heads are placed in the center hole 300, which will not affect the installation between the fixing plate 103 and the flange.

[0043] like Figure 3 As shown, a boss 203 is provided on the second limiting plate 201; in the connected state, the boss 203 is placed inside the rotating part 400; specifically, a groove is provided on the rotating part 400, and the groove is adapted to the boss 203; in this way, after the second connecting body 200 is placed on the rotating part 400, the boss 203 is placed in the groove, which avoids the second connecting body 200 from lateral displacement.

[0044] In this utility model, the first limiting plate 101 and the second limiting plate 201 are fixed to the rotating part 400 by the first fixing member; in order to further increase the fixing strength between the first connecting body 100 and the second connecting body 200 and the rotating part 400, it is preferable that a first connecting hole 108 is provided at one end of the first connecting body 100, and a second connecting hole 204 is provided on the second connecting body 200, penetrating the second limiting plate 201 and the boss 203; in the connected state, the third fixing member passes through the second connecting hole 204 and connects to the first connecting hole 108; in this way, the connection strength between the first connecting body 100 and the second connecting body 200 can be increased by the third fixing member; preferably, the third fixing member is a bolt, and the first connecting hole 108 is provided with an internal thread. When the third fixing member is placed in the first connecting hole 108, the third fixing member is threadedly connected to the first connecting hole 108;

[0045] In addition, to prevent the third fastener from being placed on the outer surface of the second connector 200 after connection, it is preferable to provide a countersunk hole 205 on the second connector 200; when the third fastener is connected to the first connection hole 108, the nut of the third fastener is placed in the countersunk hole 205 to ensure that the nut of the third fastener is not higher than the surface of the second connector 200.

[0046] like Figure 2 or Figure 3As shown, the first limiting part 102 is the first opening; the second limiting part 202 is the second opening; the first opening and the second opening respectively achieve engagement with the first fixing member, and limit the rotation through the first opening and the second opening to prevent the first connecting body 100 or the second connecting body 200 from slipping; of course, the first limiting part 102 and the second limiting part 202 can also be through holes, one end of the first fixing member is locked with the second limiting plate 201, and the other end can be connected with a nut and locked with the first limiting plate 101 by the nut; or an internal thread can be opened in the through hole on the first limiting plate 101, and the first fixing member passes through the through hole on the second limiting plate 201 and the rotating part 400 in sequence and is threadedly connected to the through hole on the first limiting plate 101, thereby fixing the first limiting plate 101 and the second limiting plate 201 with the rotating part 400.

[0047] like Figure 2 As shown, a plurality of first limiting parts 102 and a plurality of fixing holes 105 are staggered, so that when the drive member 500 is started, the torque can generate a certain angle to buffer the impact of the torque on the rotating member 400.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
