Description

Technical Field

[0001] This application relates to the technical field of speed reducers, and particularly to a worm and worm gear drive connector. Background Art

[0002] As an important mechanical transmission device, speed reducers are widely used in industrial production, especially in fields such as automated production lines and robots. The main function of a speed reducer is to reduce the rotational speed and increase the torque, thereby ensuring the working efficiency and stability of the equipment. With the development of modern industry and the progress of technology, the performance requirements for speed reducers are getting higher and higher, especially the requirements for installation accuracy, working stability, and reliability are becoming increasingly prominent.

[0003] In the prior art, when the connector is connected to the speed reducer housing, the speed reducer housing has a connection channel. At one end of the connection channel of the speed reducer housing, there is a connection ring. One end of the connection ring is connected to one end of the connection channel, and the other end is connected to one end of the connector. The connection between the connection ring and the speed reducer housing and between the connection ring and the connector is detachably installed in the form of bolt connection, so as to connect and fix the connector to the speed reducer housing and achieve power transmission. However, such a "split-type" connector has problems such as cumbersome installation and insufficient overall stiffness in actual use, which may cause displacement or loosening during the operation of the equipment, seriously affecting the working stability and service life of the speed reducer.

[0007] By adopting the above technical solution, by integrally forming the connector body and the connecting ring, when installing the connector body, the connecting ring of the connector body is inserted into the connecting channel of the reduction gearbox, and then connected and fixed through a connecting member, so that the connector body and the reduction gearbox are connected as a whole; after the connector body is fixed, the connecting ring can be kept inserted into the connecting channel of the reduction gearbox, improving the installation convenience of the overall structure; in addition, the integral formation between the connector body and the connecting ring can improve the overall stiffness between the connector body and the connecting ring (compared with the way of connecting the connector and the connecting ring by bolts), reducing the possibility of loosening that may occur during equipment operation, and thus improving the stability of the overall structure.

[0008] Optionally, a first sealing groove is formed in the outer peripheral wall of the connecting ring, and the first sealing groove is arranged in a ring shape around the central axis of the connecting ring; a first sealing ring is embedded in the first sealing groove, and the outer peripheral wall of the first sealing ring abuts against the inner peripheral wall of the connecting channel.

[0009] By adopting the above technical solution, through the arrangement of the first sealing ring, after the connecting ring is inserted into the connecting channel, the outer peripheral wall of the first sealing ring abuts against the inner peripheral wall of the connecting channel, thereby improving the sealing effect between the connecting ring and the reduction gearbox.

[0041] Embodiment 2:

[0042] Embodiment of this application discloses a worm and worm gear transmission connector.

[0043] Referring to Figure 4 , the difference between the worm and worm gear transmission connector disclosed in the embodiment of this application and Embodiment 1 is that:

[0044] In this embodiment, a pressing ring 4 is sleeved on the outer peripheral wall of the connecting cylinder 13 in a sliding manner. The pressing ring 4 is arranged in a ring shape around the central axis of the connecting cylinder 13. The pressing ring 4 is located on the side of the connecting convex ring 14 away from the reduction gearbox body 2. An installation groove is formed on the side wall of the connecting convex ring 14 close to the pressing ring 4. A pressing spring 41 is installed in the installation groove. One end of the pressing spring 41 is fixedly connected to the inner wall of the installation groove, and the other end is fixedly connected to the pressing ring 4. There is a gap between the pressing ring 4 and the connecting convex ring 14 under the normal state of the pressing spring 41.

[0045] The tightening ring 4 is provided with a through hole 42 for the connecting bolt 3 to pass through. The inner diameter of the through hole 42 is larger than the inner diameter of the first connecting hole 141. When the connecting bolt 3 is tightened, the connecting bolt 3 pushes the tightening ring 4 to abut against the connecting convex ring 14, so that the tightening spring 41 is deformed and stores elastic force.

[0046] Referring to Figure 4 , a second sealing groove 142 is formed in the side wall of the connecting convex ring 14 close to the speed reduction box body 2. The second sealing groove 142 is arranged in a ring shape around the central axis of the connecting ring 11; a second sealing ring 15 is embedded in the second sealing groove 142. The side wall of the second sealing ring 15 away from the connecting convex ring 14 abuts against the side wall of the speed reduction box body 2 close to the connecting convex ring 14. The second sealing ring 15 is an "O-ring" made of rubber.

[0047] The implementation principle of Embodiment 2 of this application is as follows: After the connecting bolt 3 is tightened into the second connecting hole 22, the connecting bolt 3 can push the tightening ring 4 so that the tightening ring 4 abuts against the connecting convex ring 14, thereby squeezing the tightening spring 41. After the tightening spring 41 is deformed, the elastic force acts on the connecting bolt 3 in the opposite direction, keeping the connecting bolt 3 in a tightened state and reducing the possibility of the connecting bolt 3 loosening during the operation of the equipment.

[0048] After the connecting bolt 3 is tightened, the second sealing ring 15 abuts against the side wall of the speed reduction box body 2. Through the arrangement of the second sealing ring 15, the combination of the first sealing ring 12 and the second sealing ring 15 can further improve the sealing effect of the overall structure.

[0049] Embodiment 3:

[0050] This application embodiment discloses a worm and worm gear transmission connector.

[0051] Referring to Figure 5 , the difference between the worm and worm gear transmission connector disclosed in this application embodiment and Embodiment 2 is as follows:

[0052] In this embodiment, the connecting convex ring 14 is provided with an extrusion member 5. When the connecting bolt 3 is tightened, the extrusion member 5 forces the second sealing ring 15 to abut tightly against the side wall of the speed reduction box body 2 close to the connecting convex ring 14, and the second sealing ring 15 is deformed; the extrusion member 5 includes an extrusion ring 51 and a push rod 52. The extrusion ring 51 is slidably installed in the second sealing groove 142. The extrusion ring 51 is arranged in a ring shape around the central axis of the connecting ring 11. The extrusion ring 51 is located on the side of the second sealing ring 15 away from the speed reduction box body 2. The extrusion ring 51 and the second sealing ring 15 are fixedly connected in an adhesive form; one end of the push rod 52 is fixedly connected to the extrusion ring 51, and the other end passes through the connecting convex ring 14 and is fixedly connected to the tightening ring 4.

[0053] The implementation principle of Embodiment 3 of this application is as follows: After the connecting bolt 3 is tightened, the connecting bolt 3 pushes the abutting ring 4 to abut against the connecting convex ring 14. During the movement of the abutting ring 4, the extrusion ring 51 is displaced by the push rod 52, thereby extruding the second sealing ring 15, so that the second sealing ring 15 abuts tightly against the side wall of the reduction gearbox 2 close to the connecting convex ring 14, improving the fitting degree between the second sealing ring 15 and the reduction gearbox 2, and further improving the sealing effect of the second sealing ring 15.
