Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a coupling with a positioning and installation structure. Background Art

[0002] A coupling is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms so that they rotate together to transmit torque. In high-speed and heavy-load power transmission, some couplings also have the functions of buffering, vibration reduction and improving the dynamic performance of the shaft system. The coupling consists of two halves, which are connected to the driving shaft and the driven shaft respectively. Generally, most power machines are connected to the working machine with the help of couplings.

[0003] When the existing coupling is installed on the shaft, the coupling and the shaft are connected by a key. The key connection can only position the coupling radially but cannot fix the coupling axially, which causes the coupling to easily undergo axial displacement on the shaft, affecting the stability of the connection. Therefore, in view of the above situation, there is an urgent need to develop a coupling with a positioning and mounting structure that is easy to position and fix and has higher installation stability, so as to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A coupling with a positioning and mounting structure, comprising a connecting sleeve, a fastening bolt, a buffer mechanism, a mounting and fixing mechanism and a nut, wherein the number of the connecting sleeves is two, a buffer mechanism is installed between the two connecting sleeves, the two connecting sleeves and one buffer mechanism are fixed by fastening bolts and nuts, a positioning key groove is provided in each of the connecting sleeves, and a mounting and fixing mechanism extending to the interior of each of the connecting sleeves is installed on each of the connecting sleeves, the mounting and fixing mechanism comprises: a threaded sleeve, a threaded rod, a clamping ring and a limiting guide rod, the threaded sleeve is rotatably connected to the connecting sleeve, a threaded rod passing through the threaded sleeve is installed in the threaded sleeve, a clamping ring is fixed to the bottom of the threaded rod, and two limiting guide rods passing through the connecting sleeve are fixed on the upper side of the clamping ring, and the limiting guide rods are slidably connected to the connecting sleeve.

[0007] Preferably, the connecting sleeve is made of No. 45 steel.

[0008] Preferably, the bottom of the clamping ring is provided with anti-slip grooves, and a plurality of toggle rods are fixed to the outer side of the threaded sleeve.

[0009] Preferably, the buffer mechanism comprises a buffer pad and a buffer spring, the buffer pad is made of rubber, and a plurality of buffer springs are installed on both the left and right sides of the buffer pad.

[0010] Preferably, each of the connecting sleeves is provided with a plurality of mounting holes for mounting buffer springs.

[0011] The beneficial effects of the utility model are as follows: when the coupling with the positioning installation structure is used, the shaft is inserted into the connecting sleeve, and the raised key on the shaft is inserted into the positioning keyway, thereby positioning the connecting sleeve, and then the threaded sleeve is driven to rotate by twisting the toggle rod, and the threaded rod and the clamping ring are driven to move by the rotation of the threaded sleeve, so that the clamping ring is pressed onto the shaft, thereby increasing the stability of the connection between the connecting sleeve and the shaft, and preventing the connecting sleeve from axially moving on the shaft; when encountering an axial impact, the buffer pad and the buffer spring can buffer and absorb the axial impact, thereby reducing the axial impact force. In summary, the utility model is easy to position and fix, and has higher installation stability; it has a buffering function. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] 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.

[0020] Specific examples are given below.

[0021] See also Figure 1 to Figure 5 In an embodiment of the utility model, a coupling with a positioning and mounting structure includes a connecting sleeve 1, a fastening bolt 2, a buffer mechanism 3, a mounting and fixing mechanism 4 and a nut 5. The number of connecting sleeves 1 is two, and the connecting sleeve 1 is made of 45 steel. A buffer mechanism 3 is installed between the two connecting sleeves 1. The two connecting sleeves 1 and a buffer mechanism 3 are fixed by fastening bolts 2 and nuts 5. A positioning keyway 101 is provided in each connecting sleeve 1. During installation, the key on the shaft is inserted into the positioning keyway 101 to position the connecting sleeve 1. Each connecting sleeve 1 is equipped with a mounting and fixing mechanism 4 extending into the interior thereof. The mounting and fixing mechanism 4 includes: A threaded sleeve 401, a threaded rod 402, a clamping ring 403 and a limiting guide rod 404. The threaded sleeve 401 is rotatably connected to the connecting sleeve 1. A threaded rod 402 is installed inside the threaded sleeve 401 to penetrate the threaded rod 402. A clamping ring 403 is fixed to the bottom of the threaded rod 402. The bottom of the clamping ring 403 is provided with anti-slip grooves 4031. Two limiting guide rods 404 that penetrate the connecting sleeve 1 are fixed to the upper side of the clamping ring 403. The limiting guide rods 404 are slidably connected to the connecting sleeve 1. The movement of the clamping ring 403 and the threaded rod 402 is limited by the limiting guide rods 404 so that they cannot rotate but can only move in a straight line. A plurality of toggle rods 4011 are fixed to the outside of the threaded sleeve 401.

[0022] The buffer mechanism 3 includes: a buffer pad 301 and a buffer spring 302. The buffer pad 301 is made of rubber. Multiple buffer springs 302 are installed on the left and right sides of the buffer pad 301. Each connecting sleeve 1 is provided with multiple mounting holes 102 for installing the buffer spring 302. When encountering axial impact, the buffer pad 301 and the buffer spring 302 can buffer and absorb the axial impact, thereby reducing the axial impact force.

[0023] Working principle: When using the coupling with a positioning and mounting structure, the shaft is inserted into the connecting sleeve 1, and the raised key on the shaft is inserted into the positioning keyway 101, thereby positioning the connecting sleeve 1, and then the threaded sleeve 401 is driven to rotate by turning the toggle rod 4011, and the threaded sleeve 401 is driven to rotate by the rotation of the threaded sleeve 401, so that the threaded rod 402 and the clamping ring 403 are moved, so that the clamping ring 403 is pressed onto the shaft, thereby increasing the stability of the connection between the connecting sleeve 1 and the shaft, and preventing the connecting sleeve 1 from axially moving on the shaft; when encountering axial impact, the buffer pad 301 and the buffer spring 302 can buffer and absorb the axial impact, thereby reducing the axial impact force.
