Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to an easily installable coupling. Background Technique

[0002] A coupling, also known as a shaft coupling, is an essential component used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together;

[0003] When connecting the ends of two shafts through a coupling, the most important thing is to align the axes of the two shafts. If the axes of the two shafts are not on the same straight line, stress concentration is likely to occur at the connection of the two shafts, and in severe cases, it may even cause the coupling to break. The commonly used materials for the buffer pads in existing compensating couplings are rubber, polyurethane, etc., which are prone to aging and deformation. For this reason, we propose an easily installable coupling. Content of the Utility Model

[0004] Aiming at the deficiencies of the poor deviation compensation effect of existing couplings, the utility model provides an easily installable coupling, which has the advantages of compensating through the telescopic movement of the strip-shaped blocks in the strip-shaped grooves and having a large compensation distance, and solves the problems raised in the above background technique.

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions:

The other end of the strip-shaped groove penetrates through the side of the support seat body. At least one support wheel is rotatably installed on the inner walls of both sides of each strip-shaped groove, and the support wheels all extend into the strip-shaped groove;

[0007] One end of the installation shaft is coaxially placed in the placement hole and there is an activity gap between the two. Radially installed on the end of the installation shaft are strip-shaped blocks corresponding to the strip-shaped grooves in terms of position and quantity. The strip-shaped blocks are respectively placed in the strip-shaped grooves, and the side surfaces of the strip-shaped blocks are in contact with the support wheels.

[0008] Preferably, connection sleeves are coaxially arranged at the ends of the installation disc and the installation shaft away from each other. The connection sleeves are sleeved on the ends of the shafts and are connected by keys.

[0010] Multiple placement grooves are respectively arranged on both sides of the installation groove. The support wheels are installed on the support shafts, and both ends of the support shafts are respectively placed in the installation grooves.

[0011] Preferably, it further includes a sealing cover. A socket is provided at the center of the sealing cover. The socket is sleeved on a connecting sleeve connected to the mounting shaft. There is a gap between the connecting sleeve and the socket. The edge of the sealing cover is connected to the mounting disc.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: an easily installable coupling, including a mounting plate 1 and a mounting shaft 11. The mounting plate 1 and the mounting shaft 11 are oppositely arranged, and connection sleeves 3 are coaxially provided at the ends of the mounting plate 1 and the mounting shaft 11 away from each other. The connection sleeve 3 is sleeved on the end of the shaft and the two are connected by a key (flat key), that is, at least one keyway 12 is provided on the inner wall of the connection sleeve 3.

[0024] In the middle of one side of the mounting plate 1, a support seat body 8 is coaxially provided. Here, the shape of the support seat body 8 is a regular symmetric body, aiming to maintain balance when rotating together with the mounting plate 1. A placement hole 10 is provided at the center of the support seat body 8. Multiple strip-shaped grooves 2 radially arranged and communicating with each other are provided at the edge of the placement hole 10. The number of strip-shaped grooves 2 is at least two and they are symmetrically arranged. The other end of the strip-shaped groove 2 penetrates through the side of the support seat body 8. At least one support wheel 5 is rotatably installed on the inner walls on both sides of each strip-shaped groove 2;

[0025] The present application also proposes a specific installation method for the support wheel 5, as Figure 1 and Figure 3 shown. Installation grooves 4 are provided on the inner walls on both sides of each strip-shaped groove 2. The position of the installation groove 4 is perpendicular to the axis of the mounting plate 1, and multiple placement grooves 6 are provided on both sides of the installation groove 4. The placement grooves 6 are through grooves. The support wheel 5 is installed on the support shaft 7. Both ends of the support shaft 7 are respectively placed in the installation groove 4, and each support wheel 5 extends into the strip-shaped groove 2.

[0026] The specific structure of the mounting shaft 11 is, as Figure 1 and Figure 2 shown. Radially mounted on the end of the mounting shaft 11 are strip-shaped blocks 9 corresponding to the strip-shaped grooves 2 in terms of position and quantity. One end of the mounting shaft 11 is coaxially placed in the placement hole 10 and there is an activity gap between the two, and the strip-shaped blocks 9 are respectively placed in the strip-shaped grooves 2. The side of the strip-shaped block 9 contacts the support wheel 5. It should be noted that the gap between the support wheels 5 on both sides of the installation groove 4 is just large enough to fit the strip-shaped block 9, so that the sides on both sides of the strip-shaped block 9 contact the support wheel 5 respectively, avoiding the appearance of gaps between the two.

[0027] The supporting wheels here can be fixed on the mounting shaft 11. Of course, they can also be rotatably mounted on the mounting shaft 11. However, the supporting wheels 5 must be rigid and can preferably be supporting bearings.

[0028] It should also be noted that there must be a clearance between the mounting shaft 11 and the placement hole 10. In this way, when the two connecting sleeves 3 are mounted on the shaft, if there is a slight deviation at the two shaft ends, the strip 9 can expand and contract in the strip groove 2, and the mounting shaft 11 can also change its position in the placement hole 10. In this way, the position deviation of the two shafts can be compensated, avoiding the deficiency of the traditional rigid connection of the coupling that cannot perform deviation compensation. At the same time, during installation, only the strip 9 needs to be inserted into the corresponding strip groove 2, which is convenient for installation and disassembly.

[0029] Furthermore, in order to prevent foreign objects from entering the strip groove 2, a sealing cover 15 is provided. A socket 16 is provided at the center of the sealing cover 15. The socket 16 is sleeved on the connecting sleeve 3 connected to the mounting shaft 11. There is a clearance between the connecting sleeve 3 and the socket 16, and this clearance is used for position deviation compensation. The edge of the sealing cover 15 is connected to the mounting disc 1;

[0030] As Figure 3 shown, an annular seat 13 is provided at the edge of the mounting disc 1, and an annular flange 14 is provided at the edge of the sealing cover 15. The annular flange 14 and the sealing cover 15 are fastened by bolts, which is convenient for the installation and disassembly of the sealing cover 15.

[0031] Furthermore, there is a certain distance between the edge of the support seat body 8 and the sealing cover 15, which can avoid contact between the support seat body 8 and the sealing cover 15.

[0032] In summary, when the present utility model is in use, the two connecting sleeves 3 are respectively mounted on the ends of the two shafts. The connecting sleeve 3 and the end of the shaft can be fastened by bolts. Then, the strip 9 is inserted into each strip groove 2, which is convenient for installation and disassembly. At the same time, the strip 9 can expand and contract in the strip groove 2. Therefore, when there is a slight deviation between the two shafts, the two connecting sleeves 3 can perform deviation compensation by the movement of the strip 9 in the strip groove 2, thereby reducing the stress concentration at the connection of the two shafts.
