Description

Technical Field

[0001] This utility model relates to the field of motor drive technology, and in particular to a motor with a speed regulation structure. Background Technology

[0002] A geared motor is a motor with a gear reducer. This type of motor is also commonly referred to as a gearbox motor or a geared motor. Existing geared motors typically have the motor output end fixedly connected to the gearbox mechanism. If the motor is damaged, it is inconvenient to replace the motor. Therefore, a geared motor with a speed regulating mechanism is proposed.

[0003] Referring to Chinese Patent No. CN222052787U, which discloses a gear reducer motor with a speed regulating mechanism, this gear reducer motor has a connecting post installed at the output end of the variable frequency motor, and a mounting block with a slot matching the connecting post. The mounting block is engaged with the connecting block by a symmetrically arranged moving locking block mechanism inside. When the variable frequency motor needs to be disassembled, rotating the throttle moves the threaded locking block. When the threaded locking block is no longer in contact with the connecting post, the connecting post and the mounting block can be separated, thus facilitating the removal and replacement of the variable frequency motor. However, when disassembling the variable frequency motor, this gear reducer motor with a speed regulating mechanism requires rotating the throttle to drive the threaded rod to move the threaded locking block. The long stroke of the threaded rod driving the threaded locking block results in a long disassembly process, which cannot achieve quick disassembly and assembly of the variable frequency motor, and the convenience is still insufficient. Utility Model Content

[0004] The purpose of this invention is to provide a motor with a speed regulation structure that has a quick-release effect, effectively solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A motor with a speed-regulating structure includes a gearbox containing a gear reduction mechanism and a variable frequency motor disposed on the side of the gearbox. One end of the input shaft in the gear reduction mechanism extends through to the outside of the gearbox, and a retaining cavity is provided on the outer end of the input shaft. A retaining rod is provided on the end face of the output shaft of the variable frequency motor, and the retaining rod is fitted into the retaining cavity. A push mechanism capable of feeding and retracting is provided on the outside of the gearbox. When the push mechanism feeds, it can press the variable frequency motor into place, thereby pressing and limiting the retaining rod in the retaining cavity.

[0007] Therefore, it can be seen that by using the jacking mechanism to press the variable frequency motor into place and pressing the clamp rod into the clamp cavity, the output shaft and input shaft are connected. During disassembly, the jacking mechanism retracts to cancel the pressing of the variable frequency motor, and the clamp rod is pulled out from the clamp cavity, so that the variable frequency motor and the gearbox can be quickly separated. Compared with the technical solution provided by the reference patent, this application makes the disassembly and assembly of the variable frequency motor faster and more convenient, and is more conducive to the disassembly, inspection or replacement of the variable frequency motor.

[0008] Furthermore, the cross-section of the card cavity is rectangular, and the cross-section of the card rod is rectangular and matches the card cavity.

[0009] Furthermore, the jacking mechanism includes a mounting bracket, a mounting plate, a drive unit, and a jacking plate. Two mounting brackets are fixed to the side of the gearbox, and a mounting plate is fixed to the ends of the two mounting brackets. The drive unit is mounted on the mounting plate, and the jacking plate is mounted on the telescopic end of the drive unit. The jacking plate is in contact with the end face of the variable frequency motor away from the output shaft to achieve the pressing effect.

[0010] Furthermore, the drive device is an electric push cylinder, which is fixed on the mounting plate, and its telescopic rod extends through to the other side of the mounting plate. The push plate is fixed on the telescopic rod end of the electric push cylinder.

[0011] Furthermore, on the side of the gearbox, a ring seat is fixed around the input shaft. Several insert rods are evenly distributed on the ring seat. A retaining ring is fixedly welded to the outside of the variable frequency motor. Several retaining holes are evenly distributed on the retaining ring. When the variable frequency motor is pressed into place, each insert rod is matched and locked into the retaining hole.

[0012] Furthermore, mounting feet are fixed to the ends of both mounting brackets away from the mounting plate, and the mounting feet are detachably fastened to the side of the gearbox by fastening bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] This utility model utilizes a jacking mechanism to press the variable frequency motor into place, and presses and limits the clamp rod within the clamp cavity, connecting the output shaft and input shaft. During disassembly, the jacking mechanism retracts to release the pressing of the variable frequency motor, and the clamp rod is pulled out from the clamp cavity, allowing the variable frequency motor and gearbox to be quickly separated. Compared with the technical solution provided by the reference patent, this application makes the disassembly and assembly of the variable frequency motor faster and more convenient, and is more conducive to the disassembly, inspection, or replacement of the variable frequency motor.

[0015] When the locking rods are aligned and inserted into the locking cavity, each locking rod on the annular seat is inserted into the locking hole on the retaining ring. After the variable frequency motor is pressed into place, the insertion and cooperation between the locking rods and the locking holes can provide multi-point support for the variable frequency motor, increase the firmness of the variable frequency motor during installation, and effectively ensure the stability of the variable frequency motor when it is used in conjunction with the gear reduction structure for speed regulation.

[0016] This utility model utilizes fastening bolts to secure the mounting feet to the side of the gearbox, thereby enabling the mounting bracket to be installed. This makes the mounting bracket detachable, facilitating the removal of the entire pushing mechanism from the side of the gearbox and meeting the needs of reagent use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Please see Figures 1-4The present invention provides a motor with a speed regulation structure, including a gearbox 1 with a gear reduction mechanism inside and a variable frequency motor 2 disposed on the side of the gearbox 1. One end of the input shaft 11 in the gear reduction mechanism extends through to the outside of the gearbox 1. The gear reduction mechanism is the same as that in the reference patent. The specific structure and working principle will not be described in detail. The input shaft 11 in this application is the first rotating rod in the reference patent.

[0024] The input shaft 11 has a retaining cavity 111 on its outer end. The output shaft 21 of the variable frequency motor 2 has a retaining rod 211 on its end face. The retaining rod 211 is fitted into the retaining cavity 111. The gearbox 1 has a push mechanism 3 on its outer side that can feed and retract. When the push mechanism 3 feeds, it can press the variable frequency motor 2 into place, thereby pressing and limiting the retaining rod 211 in the retaining cavity 111.

[0025] When installing the variable frequency motor 2, the locking rod 211 at the end of the output shaft 21 is aligned and inserted into the locking cavity 111. Then, the push mechanism 3 is used to feed the motor 2 into place and press the locking rod 211 into the locking cavity 111, thus connecting the output shaft 21 and the input shaft 11. When disassembling, the push mechanism 3 is used to retract the motor 2, canceling the pressing and pulling the locking rod 211 out of the locking cavity 111, thus quickly separating the variable frequency motor 2 from the gearbox 1.

[0026] The variable frequency motor 2 is pressed into place by the push mechanism 3, and the clamping rod 211 is pressed and limited in the clamping cavity 111, which connects the output shaft 21 and the input shaft 11. When disassembling, the push mechanism 3 retracts to cancel the pressing of the variable frequency motor 2, and the clamping rod 211 is pulled out from the clamping cavity 111, so that the variable frequency motor 2 and the gearbox 1 can be quickly separated. Compared with the technical solution provided by the reference patent, this application makes the disassembly and assembly of the variable frequency motor 2 faster and more convenient, and is more conducive to the disassembly, maintenance or replacement of the variable frequency motor 2.

[0027] Furthermore, the cross-section of the cavity 111 is rectangular, and the cross-section of the lever 211 is a rectangle that matches the cavity 111. By designing the cross-sections of the cavity 111 and the lever 211 to be mutually compatible rectangles, the lever 211 can be inserted into the cavity 111 to achieve a positioning effect, preventing the output shaft 21 from having the ability to rotate relative to the input shaft 11. This ensures that the output shaft 21 can effectively drive the input shaft 11 to rotate for transmission.

[0028] Specifically, the jacking mechanism 3 includes a mounting bracket 31, a mounting plate 32, a drive device 33, and a jacking plate 34. Two mounting brackets 31 are fixed to the side of the gearbox 1, and a mounting plate 32 is fixed to the ends of the two mounting brackets 31. The drive device 33 is mounted on the mounting plate 32, and the jacking plate 34 is mounted on the telescopic end of the drive device 33. The jacking plate 34 is in contact with the end face of the variable frequency motor 2 away from the output shaft 21 to achieve the pressing effect.

[0029] The drive device 33 is an electric push cylinder, which is fixed on the mounting plate 32, and its telescopic rod end extends through to the other side of the mounting plate 32. The push plate 34 is fixed on the telescopic rod end of the electric push cylinder.

[0030] By extending and retracting the electric push cylinder, the push plate 34 can be fed and retracted accordingly. When the push plate 34 is fed, it fits against the end of the variable frequency motor 2 away from the output shaft 21, thus pressing the variable frequency motor 2. When the push plate 34 is retracted, it separates from the variable frequency motor 2, thus canceling the pressing of the variable frequency motor 2.

[0031] In addition, the drive unit 33 can also be a cylinder, a hydraulic cylinder, or other linear drive elements to serve as the drive source for the feed and retraction of the push plate 34.

[0032] Specifically, on the side of the gearbox 1, an annular seat 12 is fixed around the input shaft 11. Several insert rods 13 are evenly distributed on the annular seat 12. A retaining ring 22 is fixedly welded to the outside of the variable frequency motor 2. Several retaining holes 221 are evenly distributed on the retaining ring 22. When the variable frequency motor 2 is pressed into place, each insert rod 13 is matched and locked into the retaining hole 221.

[0033] When the locking rod 211 is aligned and inserted into the locking cavity 111, each of the insert rods 13 on the annular seat 12 is inserted into the corresponding locking hole 221 on the retaining ring 22. After the variable frequency motor 2 is pressed into place, the insertion of the insert rods 13 into the locking hole 221 can provide multi-point support for the variable frequency motor 2, increase the firmness of the variable frequency motor 2 during installation, and effectively ensure the stability of the variable frequency motor 2 when it is used in conjunction with the gear reduction structure for speed regulation.

[0034] Specifically, each of the two mounting brackets 31 has a mounting foot 311 fixed to its end away from the mounting plate 32. The mounting foot 311 is detachably fastened to the side of the gearbox 1 by fastening bolts 312.

[0035] The mounting feet 311 are fastened to the side of the gearbox 1 using fastening bolts 312, thereby enabling the mounting bracket 31 to be installed. This makes the mounting bracket 31 detachable, which facilitates the removal of the entire pushing mechanism 3 from the side of the gearbox 1, thus meeting the needs of reagent use.

[0036] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
