Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, specifically a reinforced coupling for electric actuators. Background Technology

[0002] The reinforced coupling for electric actuators is a key transmission component connecting the motor and the actuator. Designed specifically for high-load, high-frequency start-stop scenarios, it is integrally molded from high-strength alloy or composite materials. By thickening the shaft diameter and optimizing the keyway structure, it enhances torque carrying capacity, achieving more than 30% higher torsional strength than ordinary couplings. The built-in elastic buffer module absorbs vibration and shock, reducing rigid wear between the motor and the actuator. It is suitable for a wider speed range (500-3000 r / min), and its upgraded sealing structure can withstand harsh environments such as dust and humidity, extending its service life in industrial settings such as metallurgy and chemical processing. Precise alignment is not required during installation, and maintenance is convenient. It is a core component ensuring the stable operation of electric actuators.

[0003] Chinese Utility Model Patent Publication No. CN220082257U discloses an electric actuator connecting device. The specification of this device states that the coupling includes a first half, a connecting block, and a second half. The first half has a first sliding strip, the connecting block has a first sliding groove and a second sliding strip, and the second half has a second sliding groove. Even when there is a deviation between the axis of the valve shaft and the axis of the electric actuator sleeve, the electric actuator can still smoothly drive the valve. However, this electric actuator connecting device lacks a reinforced connection structure for the two half-coupling components. During use, local overload can easily occur, leading to wear or breakage between the half-couplings. Furthermore, it lacks a quick-locking structure between the connecting frame one and the connecting frame two, making it inconvenient to quickly disassemble and assemble during use or assembly. This results in poor practicality and hinders its widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a reinforced coupling for electric actuators. It can effectively solve the problems of existing technologies that do not have a reinforced connection structure for the two half-couplings, which can easily cause local overload during use, leading to wear or breakage between the half-couplings. In addition, the lack of a quick-locking structure between the first and second connecting brackets makes it inconvenient to quickly disassemble and assemble during use or assembly, resulting in poor practicality and difficulty in promoting its use.

[0005] The technical solution adopted by this utility model is as follows: a reinforced coupling for an electric actuator, comprising an electric actuator and a valve body. A rotating shaft one is rotatably mounted on the end of the electric actuator near the valve body, and a rotating shaft two is rotatably mounted on the end of the valve body near the electric actuator. Flanges are fixedly mounted on the ends of the rotating shaft one and the rotating shaft two near the rotating shaft one. Half-coupling one and half-coupling two are provided between the rotating shaft one and the rotating shaft two. A connecting frame one is fixedly mounted on the end of the electric actuator near the valve body, and a connecting frame two is fixedly mounted on the end of the valve body near the electric actuator. A connecting assembly is provided between the connecting frame one and the connecting frame two. A toothed groove and a slot two are provided on the end of the half-coupling two near the half-coupling one. A toothed block and a insert block two are fixedly mounted on the end of the half-coupling one near the half-coupling two.

[0006] Preferably, the outer wall of the flange is provided with a through hole and a positioning groove. The end of the first half-coupling near the first rotating shaft and the end of the second half-coupling near the second rotating shaft are both provided with a through hole. Positioning blocks are fixedly installed at the end of the first half-coupling near the first rotating shaft and the end of the second half-coupling near the second rotating shaft. A screw adapted to the through hole and the through hole is inserted into the outer wall of the flange. A nut is threaded onto the outer wall of the screw. The positioning block and the positioning groove are inserted into each other. The cross-section of the positioning block is rectangular.

[0007] Using the above technical solution, the worker inserts the positioning block into the positioning groove, so that the flange and the first half-coupling come into contact, which can achieve the rapid positioning of the first half-coupling. Similarly, the second half-coupling can be positioned quickly.

[0008] Preferably, the screw passes through through hole one and through hole two, and the diameters of through hole one and through hole two are the same.

[0009] With the above technical solution, after the first half-coupling is quickly positioned, the operator inserts the screw through the first and second through holes, and then connects the nut to the screw thread, which can quickly fix the first half-coupling. Similarly, the second half-coupling can be quickly fixed. After long-term use, it is convenient to repair or replace it.

[0010] Preferably, a protrusion and a plug are fixedly installed at one end of the first connecting frame near the second connecting frame, and a groove and a slot are provided at one end of the second connecting frame near the first connecting frame. The protrusion is adapted to the groove, and the plug and slot are plugged in.

[0011] Using the above technical solution, the staff inserts the protrusion into the groove and inserts the first plug into the first slot, which can achieve rapid positioning of the first connecting bracket and the second connecting bracket.

[0012] Preferably, the connecting assembly includes a first fixing block, a second fixing block, a first guide groove, a first rotating plate, a first guide block, a first fixing rod, a second guide groove, a second rotating plate, a second guide block, and a second fixing rod. The first fixing block is fixedly installed on the outer wall of the first connecting frame, and the second fixing block is fixedly installed on the outer wall of the second connecting frame. The first fixing block has a first guide groove on its inner wall and a first rotating plate on its inner wall. The first guide block is fixedly installed on the outer wall of the first rotating plate, and the first fixing rod is fixedly installed on the side of the first guide block away from the first rotating plate. The second fixing block has a second guide groove on its inner wall and a second rotating plate on its inner wall. The second guide block is fixedly installed on the outer wall of the second rotating plate, and the second fixing rod is fixedly installed on the side of the second guide block away from the second rotating plate. The first guide block is adapted to the first and second guide grooves, and the second guide block is adapted to the first and second guide grooves.

[0013] With the above technical solution, after quickly positioning the connecting frame 1 and the connecting frame 2, the operator can rotate the rotating plate 1 and the rotating plate 1 by fixing rod 1 and fixing rod 2, so that the guide block 1 slides into the interior of the guide groove 2 and the guide block 2 slides into the interior of the guide groove 1, which can realize the quick locking of the connecting frame 1 and the connecting frame 2, and facilitate quick disassembly and assembly during use or assembly.

[0014] Preferably, the toothed block is adapted to the toothed groove, the second insert and the second slot are plugged in, and the cross-section of the second insert has a hexagonal structure.

[0015] Through the above technical solution, during the process of quickly positioning the connecting frame one and the connecting frame two, the toothed block is inserted into the toothed groove, and at the same time, the insert block two is inserted into the slot two. After quickly locking the connecting frame one and the connecting frame two, the half coupling one and the half coupling two can be quickly connected, which is convenient for the subsequent electric actuator to drive the valve body and has high practicality.

[0016] Preferably, there are multiple identical tooth blocks and multiple identical tooth grooves, and the multiple tooth blocks are arranged in a ring, with each tooth block corresponding to a tooth groove.

[0017] Through the above technical solution, and by designing multiple tooth blocks and tooth grooves, the transmitted torque can be transmitted evenly distributed across multiple tooth blocks during use, which significantly reduces the load on a single tooth block, improves the overall structure's resistance to damage, and thus enhances the connection strength between half-coupling one and half-coupling two, making it highly practical.

[0018] Compared with the prior art, this utility model provides a reinforced coupling for electric actuators, which has the following advantages:

[0019] 1. This reinforced coupling for electric actuators can quickly fix half coupling one and half coupling two by cooperating with the positioning block and positioning groove, screw, through hole one, through hole two and nut. After long-term use, it is easy to repair or replace it. By cooperating with the tooth block and tooth groove and the insert block two and slot two, half coupling one and half coupling two can be quickly connected, which is convenient for the subsequent electric actuator to drive the valve body. It has high practicality.

[0020] 2. This reinforced coupling for electric actuators, through the design of multiple tooth blocks and tooth grooves, can transmit torque by evenly distributing it across multiple tooth blocks during use, significantly reducing the load on individual tooth blocks and improving the overall structure's resistance to damage. This enhances the connection strength between half-coupling one and half-coupling two, making it highly practical. Through the cooperation of protrusions and grooves and insert one and slot one, quick positioning of connecting frame one and connecting frame two can be achieved. The design of the connecting components allows for quick locking of connecting frame one and connecting frame two, facilitating quick disassembly and assembly during use or assembly.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] like Figure 1-7 As shown, this utility model provides a reinforced coupling for an electric actuator, including an electric actuator 1 and a valve body 2. A rotating shaft 3 is rotatably mounted on one end of the electric actuator 1 near the valve body 2, and a rotating shaft 4 is rotatably mounted on one end of the valve body 2 near the electric actuator 1. A flange 5 is fixedly mounted on one end of the rotating shaft 3 near the rotating shaft 4 and on the other end of the rotating shaft 4 near the rotating shaft 3.

[0032] Specifically, the outer wall of flange 5 has a through hole 6 and a positioning groove 7. The end of half-coupling 8 near shaft 3 and the end of half-coupling 9 near shaft 4 both have through holes 10.

Positioning blocks 11 and positioning grooves 7 are inserted into each other, and the cross-section of positioning blocks 11 is rectangular. The advantage is that when the operator inserts positioning blocks 11 into the positioning groove 7, causing flange 5 to abut against half-coupling 8, quick positioning of half-coupling 8 can be achieved. Similarly, quick positioning of half-coupling 9 can be achieved.

[0033] Specifically, screw 12 passes through through hole 6 and through hole 10, and the diameters of through hole 6 and through hole 10 are the same. The advantage is that after quickly positioning half-coupling 8, the operator can quickly fix half-coupling 8 by passing screw 12 through through hole 6 and through hole 10, and then thread nut 13 onto screw 12. Similarly, half-coupling 9 can be quickly fixed, facilitating maintenance or replacement after prolonged use.

[0034] Specifically, a protrusion 17 and a plug 18 are fixedly installed at one end of connecting bracket 15 near connecting bracket 2 16. A groove 19 and a slot 20 are formed at one end of connecting bracket 2 16 near connecting bracket 15. The protrusion 17 fits into the groove 19, and the plug 18 and slot 20 are inserted into each other. The advantage is that by inserting the protrusion 17 into the groove 19 and simultaneously inserting the plug 18 into the slot 20, the connecting bracket 15 and connecting bracket 2 16 can be quickly positioned.

[0035] Specifically, the connecting assembly 21 includes a first fixing block 2101, a second fixing block 2102, a first guide groove 2103, a first rotating plate 2104, a first guide block 2105, a first fixing rod 2106, a second guide groove 2107, a second rotating plate 2108, a second guide block 2109, and a second fixing rod 2110. The first fixing block 2101 is fixedly installed on the outer wall of the first connecting frame 15, and the second fixing block 2102 is fixedly installed on the outer wall of the second connecting frame 16. The first guide groove 2103 is formed on the inner wall of the first fixing block 2101, and the first rotating plate 2104 is provided on the inner wall of the first fixing block 2101. The second fixing rod 2110 is fixedly installed on the outer wall of the first rotating plate 2104. Guide block 1 2105, with a fixing rod 2106 fixedly installed on the side of guide block 1 2105 away from rotating plate 1 2104. The inner wall of fixing block 2 2102 has a guide groove 2107. The inner wall of fixing block 2 2102 has a rotating plate 2108. The outer wall of rotating plate 2108 has a guide block 2109 fixedly installed. The side of guide block 2109 away from rotating plate 2108 has a fixing rod 2110 fixedly installed. Guide block 1 2105 is adapted to guide groove 1 2103 and guide groove 2107. Guide block 2109 is adapted to guide groove 1 2103 and guide groove 2107. The advantage is that after quickly positioning the connecting frame 15 and the connecting frame 26, the operator can rotate the rotating plate 1 2104 and the rotating plate 2104 by fixing rod 1 2106 and fixing rod 2110, so that the guide block 1 2105 slides into the inside of the guide groove 2107 and the guide block 2109 slides into the inside of the guide groove 2103, which can realize the quick locking of the connecting frame 15 and the connecting frame 26, and facilitates quick disassembly and assembly during use or assembly.

[0036] Example 2:

[0037] like Figure 2-7 As shown, as an improvement on the previous embodiment, to further enhance the connection strength between half-coupling 8 and half-coupling 9, specifically, the toothed block 24 is adapted to the toothed groove 22, and the insert block 25 and the slot 23 are plugged in. The cross-section of the insert block 25 is hexagonal. The advantage is that during the rapid positioning of connecting frame 15 and connecting frame 26, the toothed block 24 is inserted into the toothed groove 22, and simultaneously the insert block 25 is inserted into the slot 23. After the connecting frame 15 and connecting frame 26 are quickly locked, the half-coupling 8 and half-coupling 9 can be quickly connected, facilitating the subsequent driving of the valve body 2 by the electric actuator 1, thus demonstrating high practicality.

[0038] Specifically, multiple identical tooth blocks 24 and multiple identical tooth grooves 22 are provided, with the multiple tooth blocks 24 arranged in a ring, and each tooth block 24 corresponding to a tooth groove 22. The advantage is that, through the design of multiple tooth blocks 24 and tooth grooves 22, the transmitted torque can be evenly distributed across multiple tooth blocks 24 during use, significantly reducing the load on a single tooth block 24, improving the overall structure's resistance to damage, and thus enhancing the connection strength between half-coupling 8 and half-coupling 9, resulting in high practicality.

[0039] Working principle: During installation, the operator inserts the positioning block 11 into the positioning groove 7, causing the flange 5 to abut against the first half-coupling 8, thus quickly positioning the first half-coupling 8. Similarly, the second half-coupling 9 can be quickly positioned. After quickly positioning the first half-coupling 8, the operator inserts the screw 12 through the first through hole 6 and the second through hole 10, and then threads the nut 13 onto the screw 12, thus quickly fixing the first half-coupling 8. Similarly, the second half-coupling 9 can be quickly fixed, facilitating maintenance or replacement after prolonged use. Subsequently, the operator inserts the protrusion 17 into the groove 19 and simultaneously inserts the insert block 18 into the slot 20, thus quickly positioning the connecting frame 15 and the connecting frame 26. After quickly positioning the connecting frame 15 and the connecting frame 26, the operator rotates the rotating plate 2104 and the rotating plate 2110 using the fixing rod 2106 and the fixing rod 2110. 104, allowing guide block 1 2105 to slide into guide groove 2107 and guide block 2109 to slide into guide groove 2103, enabling quick locking of connecting bracket 1 15 and connecting bracket 2 16. This facilitates quick disassembly and assembly during use or assembly. During the quick positioning of connecting bracket 1 15 and connecting bracket 2 16, tooth block 24 is inserted into tooth groove 22, while insert block 2 25 is inserted into slot 2 23. After quickly locking connecting bracket 1 15 and connecting bracket 2 16, quick connection of half coupling 1 8 and half coupling 2 9 can be achieved, facilitating the subsequent drive of valve body 2 by electric actuator 1. This method is highly practical. During use, the transmitted torque can be evenly distributed across multiple tooth blocks 24, significantly reducing the load on a single tooth block 24 and improving the overall structure's resistance to damage, thereby enhancing the connection strength of half coupling 1 8 and half coupling 2 9. This method is highly practical.
