Description
Technical Field
[0001] This utility model relates to the field of electromechanical equipment technology, specifically to a power transmission device for electromechanical equipment. Background Technology
[0002] The power transmission device of electromechanical equipment is a core functional module that connects the power source (such as motor, engine) and the actuator (such as gear, lead screw, conveyor belt, etc.). Its core function is to realize the speed regulation of power through the energy conversion and transmission of mechanical structure or fluid medium.
[0003] When existing power transmission devices for electromechanical equipment transmit power through gears, the rigid contact between the metal gear teeth during meshing generates periodic impacts and vibrations. This not only causes significant operating noise but may also lead to the transmission of vibration energy to the main body of the equipment, affecting the overall operational stability. On the other hand, if rubber gears are used to reduce noise and vibration, although the elastic deformation of rubber can buffer the meshing impact and absorb vibration energy, the rubber itself has poor wear resistance, tear resistance, and high temperature resistance. Under long-term load, it is prone to problems such as tooth surface wear, tooth tip deformation, and even breakage, requiring frequent shutdowns to replace worn gears. This not only increases the maintenance cost and downtime losses of the equipment but also seriously affects the continuous operating efficiency of the electromechanical equipment. Therefore, we propose a power transmission device for electromechanical equipment. Utility Model Content
[0004] The purpose of this utility model is to provide a power transmission device for electromechanical equipment, in order to solve the problem in the background art that uses the elastic deformation of rubber to buffer meshing impact and absorb vibration energy, but the material itself has poor wear resistance, tear resistance and high temperature resistance, and is prone to problems such as tooth surface wear, tooth tip deformation or even breakage under long-term load, requiring frequent shutdowns to replace worn gears.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a power transmission device for electromechanical equipment, comprising a mounting plate and a drive motor, wherein the drive motor is fixedly connected to one side of the mounting plate, a transmission gear is rotatably connected to one side of the mounting plate, a transmission rod is screwed to one end of the transmission gear, a gear seat is fixedly connected to one end of the power output shaft of the drive motor, a rubber buffer ring is adhered to the outer side of the gear seat, two slots are opened on one side of the gear seat, an installation groove is opened inside the gear seat, a pressure spring is embedded in the inner cavity of the installation groove, and a pressure plate is fixedly connected to the top end of the pressure spring.
[0006] As a further description of the above technical solution: The top of the inner cavity of the mounting slot has two locking grooves, and the top of the gear seat is engaged with a rack ring.
[0007] As a further description of the above technical solution: The inner side of the rack ring is in contact with the rubber buffer ring, and the outer side of the rack ring is integrally formed with rubber racks, which are evenly distributed.
[0008] As a further description of the above technical solution: The rack ring has a movable groove inside, and a rotating rod is movably connected inside the movable groove.
[0009] As a further description of the above technical solution: The bottom end of the rotating rod passes through the gear seat and extends into the inner cavity of the mounting groove, and the bottom end of the rotating rod contacts the pressure plate. Two locking rods are fixedly connected to the outer side of the rotating rod.
[0010] As a further description of the above technical solution: The locking rod engages with the locking groove, and the inner cavity of the rotating rod is movably connected to a pressing plate. A polygonal rod is fixedly connected to the top of the pressing plate.
[0011] As a further description of the above technical solution: The top end of the polygonal rod passes through the rotating rod, and a lifting rod is fixedly connected to the top end of the polygonal rod.
[0012] As a further description of the above technical solution: A return spring is sleeved on the outer side of the polygonal rod, and two fixing plates are fixedly connected to the outer side of the lifting rod. A limit plug is fixedly connected to the bottom of the fixing plate, and the limit plug is inserted into the slot.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This device is used for power transmission in electromechanical equipment. The gear seat of this device has a built-in mounting groove, within which a pressure spring naturally extends, and the top pressure plate remains horizontal. A pre-installed mounting position for a rack ring is provided at the top. A rubber buffer ring between the two provides initial cushioning of assembly impact. During assembly, the rack ring is aligned with the mounting position and pressed down. Its internal movable groove drives the rotating rod to move downwards synchronously. The bottom end of the rotating rod presses against the pressure plate, compressing the pressure spring and causing it to slide down along the mounting groove. The locking rod on the outside of the rotating rod also moves downwards. When the locking rod aligns with the locking groove at the top of the mounting groove, the pressure spring resets, pushing the pressure plate upwards. This drives the rotating rod to engage the locking rod in the locking groove, completing the initial fixation. The entire process requires no additional tools, enabling rapid assembly. For disassembly, external force presses down on the top part of the rotating rod, causing the pressure plate to compress the spring, disengaging the locking rod from the locking groove. The rack ring can then be removed by lifting it upwards, significantly reducing maintenance and replacement time.
[0014] 2. This device is used for power transmission in electromechanical equipment. After the rack ring is initially fixed (the locking rod engages with the locking groove), the return spring inside the rotating rod naturally extends, the top pressing plate is horizontal, its top polygonal rod extends vertically, the top lifting rod is in a low position, the outer fixing plate is simultaneously in a low position, and the bottom limiting rod is inserted into the gear seat slot, forming a double lock with the locking structure. During disassembly, lifting the lifting rod moves the polygonal rod upward, the pressing plate compresses the return spring, and the fixing plate moves upward, causing the limiting rod to disengage from the slot, releasing the secondary lock. Subsequently, pressing down the lifting rod moves the rotating rod downward to release the initial lock, thus completing the rack ring disassembly. The locking and unlocking operations are continuous, and the return spring ensures that the components automatically reset, facilitating the next locking. Attached Figure Description

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0019] This utility model provides a power transmission device for electromechanical equipment, which effectively shortens the replacement time after the rubber rack wears out, reduces downtime caused by maintenance, and is especially suitable for production electromechanical equipment with high requirements for continuous operation, significantly improving the effective operating rate of the equipment. Please refer to [link / reference]. Figure 1-4 It includes mounting plate 1 and drive motor 2; Please refer to it again. Figure 1-4 The drive motor 2 is fixedly connected to one side of the mounting plate 1. A transmission gear 101 is rotatably connected to one side of the mounting plate 1. A transmission rod 102 is screwed to one end of the transmission gear 101. A gear seat 3 is fixedly connected to one end of the power output shaft of the drive motor 2. A rubber buffer ring 301 is bonded to the outside of the gear seat 3. Two slots 302 are opened on one side of the gear seat 3. An installation groove 4 is opened inside the gear seat 3. A pressure spring 401 is embedded in the inner cavity of the installation groove 4. A pressure plate 402 is fixedly connected to the top of the pressure spring 401. Two locking grooves 403 are opened at the top of the inner cavity of the installation groove 4. A rack ring 5 is snapped into the top of the gear seat 3. The inner side of the rack ring 5 is in contact with the rubber buffer ring 301. A rubber rack 501 is integrally formed on the outer side of the rack ring 5, and the rubber rack 501 is evenly distributed.
[0020] The gear seat 3 has a pre-set mounting groove 4 inside, with the pressure spring 401 in a naturally extended state. The pressure plate 402 at its top remains horizontal. The top of the gear seat 3 has a pre-reserved mounting position for the rack ring 5, and the inner side of the rack ring 5 is tightly fitted with the rubber buffer ring 301 on the outer side of the gear seat 3. The rubber buffer ring 301 can initially buffer the impact force during the assembly of the rack ring 5. When the rack ring 5 is aligned with the mounting position on the top of the gear seat 3 and pressed down, the rack ring 5 drives the rotating rod 601 in the internal movable groove 6 to move down synchronously. The bottom end of the rotating rod 601 presses against the pressure plate 402, causing the pressure plate 402 to compress the pressure spring 401 and slide down along the inner wall of the mounting groove 4. At the same time, the two locking rods 602 on the outer side of the rotating rod 601 move down with the rotating rod 601. When the locking rod 602 moves to align with the locking groove 403 at the top of the inner cavity of the mounting groove 4, the pressure spring 401 releases its elastic potential energy, pushing the pressure plate 402 to return to its original position, which in turn drives the rotating rod 601 to move upward, so that the locking rod 602 is precisely engaged in the locking groove 403, completing the initial fixation of the rack ring 5. The entire installation process does not require the use of additional tools, achieving rapid assembly. By pressing down on the relevant components at the top of the rotating rod 601 with external force, the rotating rod 601 drives the pressure plate 402 to compress the pressure spring 401 again. At this time, the locking rod 602 disengages from the locking groove 403. Then, the rack ring 5 is pulled upward, and the rack ring 5 together with the rotating rod 601 can be removed from the gear seat 3, completing the rapid disassembly and effectively shortening the component replacement time during maintenance.
[0021] Please refer to it again. Figure 1-4 The rack ring 5 has an internal movable groove 6, and a rotating rod 601 is movably connected inside the movable groove 6. The bottom end of the rotating rod 601 passes through the gear seat 3 and extends into the inner cavity of the mounting groove 4. The bottom end of the rotating rod 601 contacts the pressure plate 402. Two locking rods 602 are fixedly connected to the outside of the rotating rod 601. The locking rods 602 are engaged with the locking groove 403. A pressing plate 7 is movably connected to the inner cavity of the rotating rod 601. A polygonal rod 701 is fixedly connected to the top of the pressing plate 7. The top end of the polygonal rod 701 passes through the rotating rod 601 and a lifting rod 702 is fixedly connected to the top end of the polygonal rod 701. A return spring 703 is sleeved on the outside of the polygonal rod 701. Two fixing plates 8 are fixedly connected to the outside of the lifting rod 702. A limit plug 801 is fixedly connected to the bottom of the fixing plate 8. The limit plug 801 is inserted into the slot 302.
[0022] After the rack ring 5 is initially fixed (locking rod 602 engages with locking groove 403), the return spring 703 in the inner cavity of the rotating rod 601 is in a naturally extended state, the compression plate 7 at its top remains horizontal, the polygonal rod 701 at the top of the compression plate 7 extends vertically along the inner cavity of the rotating rod 601, and the lifting rod 702 at the top of the polygonal rod 701 is in a low position. The two fixing plates 8 on the outside of the lifting rod 702 remain in a low position along with the lifting rod 702. The limiting insert 801 at the bottom of the fixing plate 8 is precisely inserted into the slot 302 opened on one side of the gear seat 3, forming the first locking defense line. Combined with the engagement of the locking rod 602 and the locking groove 403, a double locking is formed. When it is necessary to disassemble the rack ring 5... When the lifting rod 702 is pulled upward, the lifting rod 702 drives the polygonal rod 701 to move upward along the inner cavity of the rotating rod 601. The pressing plate 7 at the top of the polygonal rod 701 simultaneously compresses the return spring 703 upward. At the same time, the fixing plate 8 on the outside of the lifting rod 702 moves upward with the lifting rod 702, so that the limiting insert 801 at the bottom of the fixing plate 8 is pulled out from the slot 302 of the gear seat 3, releasing the secondary lock. At this time, the lifting rod 702 can be pressed downward to drive the rotating rod 601 to move downward to release the initial lock, and finally realize the disassembly of the rack ring 5. The entire locking and unlocking process is smooth, and the return spring 703 can ensure that each component automatically resets after the lock is released, which is convenient for the next locking operation.
[0023] In practical use, this device is mounted on a mounting plate 1 as the base carrier. A drive motor 2 is fixed to one side of the mounting plate 1 and provides the power source. The gear seat 3, fixed to the end of its power output shaft, is the core transmission and connection component. A rubber buffer ring 301 bonded to the outside of the gear seat 3 tightly fits against the inner side of the rack ring 5 snapped onto the top. The uniformly distributed rubber racks 501 integrally formed on the outside of the rack ring 5 mesh with a transmission gear 101 rotatably connected to one side of the mounting plate 1. A transmission rod 102 fixed to one end of the transmission gear 101 is used to output power outwards. During operation, after the drive motor 2 starts, it drives the gear seat 3 to rotate synchronously. The gear seat 3, through its snap-fit engagement with the rack ring 5, drives the rack ring 5 to rotate. The rubber racks 501 on the outside of the rack ring 5 mesh with the transmission gear 101, thereby driving the transmission gear 101 to rotate. Finally, power transmission is completed through the transmission rod 102. Furthermore, the rubber racks 501 and the rubber buffer ring 301 can buffer meshing impacts and reduce operating noise. The rack ring 5 is installed through the gear seat 3. The pressure spring 401 in the internal mounting slot 4 pushes the pressure plate 402, causing the locking rod 602 on the outside of the rotating rod 601 to engage in the locking groove 403 for initial fixation. At the same time, the return spring 703 in the inner cavity of the rotating rod 601 pushes the extrusion plate 7, causing the polygonal rod 701 and the lifting rod 702 to move downwards, so that the limiting insert 801 at the bottom of the fixing plate 8 inserts into the slot 302 of the gear seat 3 to complete the secondary locking, ensuring stable transmission of the rack ring 5 during operation. When the rubber rack 501 is worn and needs to be replaced, the lifting rod is pulled upwards. 702 causes the limiting rod 801 to disengage from the slot 302, releasing the secondary lock. Then, press down on the lifting rod 702 to move the rotating rod 601 down, causing the locking rod 602 to disengage from the locking groove 403. Finally, pull up the rack ring 5 to complete the disassembly. When replacing the rack ring 5, align it with the installation position and press it down. The pressure spring 401 resets, causing the locking rod 602 to engage in the locking groove 403. At the same time, the reset spring 703 resets, causing the limiting rod 801 to insert into the slot 302. After the quick replacement is completed, power transmission can be restored.
