Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and specifically to an easy-to-maintain reducer clutch. Background Technology

[0002] The washing machine reducer clutch, also known as a speed reducer, is a key component of the transmission system in a pulsator washing machine. Its main function is to reduce the motor speed and increase torque, thereby driving the pulsator. Washing machine speed reducers mainly include concentric gear reducers, which are widely used in pulsator washing machines due to their small size, high stability, and low noise. Common faults in washing machine speed reducer clutches include water leakage and gear grinding. These problems are usually caused by water leakage in the reducer or water seal. Repairing these issues requires disconnecting the power supply, removing the back cover of the washing machine, checking for leaks, and replacing the leaking components. The existing technology has the following problems:

[0003] Because existing washing machine reducer clutches are typically fixed to the bottom of the impeller using mounting plates and bolts, and the impeller shaft at the top of the reducer clutch is connected to the impeller for fixation, this method, while secure, requires repeated bolt removal and installation during later disassembly, maintenance, and repair. This reduces efficiency and hinders quick maintenance. Furthermore, since the washing machine reducer clutch's pulleys rely on belts for transmission, and the belt and pulleys require limiting, disassembly and replacement of the belt during maintenance and replacement are also inconvenient.

[0004] This invention provides an easy-to-maintain speed reducer clutch to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand

[0023] Understood. The present invention will now be further described in conjunction with specific implementation methods.

[0024] like Figure 1 , Figure 2 , Figure 3As shown, this utility model provides an easy-to-maintain reducer clutch, including a reducer clutch body 1, a quick-release mechanism 2 on the top of the reducer clutch body 1, a ratchet 3 at the bottom of the reducer clutch body 1, a pulley mechanism 4 at the bottom of the ratchet 3, an installation ring 11 fixedly installed on the upper outer wall of the reducer clutch body 1, the installation ring 11 having a plurality of installation holes 111 in a circular array, the quick-release mechanism 2 including a docking plate 21, fixing mechanisms 22 on the left and right sides of the top of the docking plate 21, a plurality of threaded holes 23 in a circular array, the plurality of threaded holes 23 being vertically aligned with the plurality of installation holes 111, and pentalobe bolts 24 being threaded into the inner rings of the plurality of threaded holes 23, and clamping plates 211 fixedly installed on the left and right sides of the top of the docking plate 21. Locking holes 212 are provided on both the front and back sides of the back of the card plate 211. A buckle hole 213 is provided at the center of the back of both card plates 211. Both fixing mechanisms 22 include mounting plates 221. A slot 222 is provided at the bottom of each mounting plate 221. The slots 222 engage with the card plates 211. Fixing plates 223 are fixedly installed on both the front and back sides of the mounting plates 221. Each fixing plate 223 has a bolt hole 224 that extends vertically. Locking screw holes 225, extending into the cavity of the slot 222, are provided on both the front and back sides of the back of the two slots 222. The locking screw holes 225 are aligned horizontally with the locking holes 212. A locking screw 226 is installed on the inner thread of the locking screw hole 225. A knob 227 is fixedly installed at the end of the locking screw 226 away from the mounting plate 221.

[0025] When installing the reducer clutch body 1 for the first time, align the threaded hole 23 of the mating plate 21 with the mounting hole 111 on the top of the mounting ring 11 on the outer wall of the reducer clutch body 1. Then, use several pentagonal bolts 24 to fix the mating plate 21 to the top of the mounting ring 11. Then, align the two mounting plates 221 with the fixing plates 223 on their front and rear sides with the plate holes at the bottom of the washing machine cavity that separate it from the impeller. Use bolts to pass through the bolt holes 224 to fix both mounting plates 221. After fixing, the impeller shaft of the reducer clutch body 1 will pass through the separating plate and connect to the bottom of the impeller. At the same time, the mating plate 21 is also located at the bottom of the two mounting plates 221. When performing maintenance and disassembly later, simply remove the locking screw 226 in the locking mating screw hole 225 by rotating the knob 227 to separate it from the locking hole 212 in the clamping plate 211 and release the limit on the clamping plate 211.

[0026] like Figure 4As shown, both mounting plates 221 are provided with positioning chambers 2211. Three compression springs 2212 are fixedly installed on the side of the inner wall of the two positioning chambers 2211 away from the slots 222. The other end of the compression springs 2212 is fixedly installed with pressure plates 2213. The opposite sides of the two pressure plates 2213 are fixedly installed with inclined buckles 2214. The opposite ends of the two inclined buckles 2214 pass through the inner cavity of the two slots 222 and engage with the buckle holes 213. A connecting rod 2215 is fixedly installed at the center of the side of the two pressure plates 2213 away from the inclined buckles 2214. The connecting rod 2215 is located inside the middle one of the three compression springs 2212. The ends of the two connecting rods 2215 away from the pressure plates 2213 pass through the opposite sides of the two mounting plates 221 and are fixedly installed with pull rods 2216.

[0027] During disassembly, pulling the pull rod 2216 on one side of the two mounting plates 221 will pull the pressure plate 2213 using the connecting rod 2215, thereby disengaging the inclined snap fastener 2214 from the snap fastener hole 213. This allows the entire reducer clutch body 1 to be directly detached. After maintenance, during installation, simply align the two snap plates 211 on the top of the mating plate 21 with the snap grooves 222 on the bottom of the two mounting plates 221 and snap them in. This will cause the snap plates 211 to press against the inclined surface of the inclined snap fastener 2214, ultimately causing the inclined snap fastener 2214 to compress. The spring 2212 is compressed, causing the inclined buckle 2214 to engage in the buckle hole 213. The top horizontal surface of the inclined buckle 2214 limits the position of the plate 211. At this time, the locking screw hole 225 will be aligned with the locking hole 212 again. Then, the locking screw 226 is aligned with the locking screw hole 225 and the knob 227 is reversed, so that the locking screw 226 is smoothly threaded into the locking hole 212, further strengthening the connection stability between the plate 211 and the slot 222, and completing the installation.

[0028] like Figure 5 As shown, the pulley mechanism 4 includes a pulley 41, a limiting disk 42 fixedly installed on the top of the pulley 41, the top center of the limiting disk 42 being fixedly connected to the bottom of the ratchet 3, a disassembly threaded hole 43 being opened at the bottom center of the pulley 41, a disassembly threaded post 44 being installed on the inner ring thread of the disassembly threaded hole 43, and a limiting disk 45 fixedly installed at the bottom of the disassembly threaded post 44, the limiting disk 45 being the same size as the limiting disk 42;

[0029] When the belt needs to be disassembled for maintenance, it is not necessary to remove the entire reducer clutch body 1. Simply rotate the limiting plate 45 at the bottom of the pulley 41 to rotate and separate the disassembly threaded post 44 from the disassembly threaded hole 43, thereby removing the limiting plate 45 at the bottom of the pulley 41, releasing the belt from its limit, and allowing the taut belt to be directly removed for maintenance.

[0030] The working principle of this easy-to-maintain reducer clutch will be explained in detail below.

[0031] like Figure 1-5 As shown, when installing the reducer clutch body 1 for the first time, the threaded hole 23 of the mating plate 21 is aligned with the mounting hole 111 on the top of the mounting ring 11 on the outer wall of the reducer clutch body 1. Then, several pentagonal bolts 24 are used to fix the mating plate 21 to the top of the mounting ring 11. Then, the two mounting plates 221 are aligned with the fixing plates 223 on their front and rear sides, and the plate holes separating the impeller from the bottom of the washing machine cavity are aligned with the fixing plates 223. Bolts are then used to pass through the bolt holes 224 to fix both mounting plates 221. After fixing, the impeller shaft of the reducer clutch body 1 will pass through the separating plate holes. The plate is connected to the bottom of the impeller, and the mating plate 21 is also located at the bottom of the two mounting plates 221. During later maintenance and disassembly, simply remove the locking screw 226 in the locking mating screw hole 225 using the rotating knob 227, separating it from the locking hole 212 on the clamping plate 211, releasing the clamping plate 211 from its limit. Simultaneously, pull the pull rod 2216 on one side of the two mounting plates 221. Then, use the connecting rod 2215 to pull the pressure plate 2213, causing the inclined snap fastener 2214 to disengage from the snap fastener hole 213, thus allowing the entire reducer clutch body to move straight... After the initial detachment and maintenance, during reinstallation, simply align the two locking plates 211 on the top of the mating plate 21 with the slots 222 on the bottom of the two mounting plates 221 and insert them. This will cause the locking plates 211 to press against the inclined surface of the inclined buckle 2214, ultimately compressing the compression spring 2212. This allows the inclined buckle 2214 to engage in the buckle hole 213. The horizontal surface at the top of the inclined buckle 2214 then limits the locking plate 211. At this point, the locking screw hole 225 will align with the locking hole 212 again. Then, directly align the locking screw 226 with the locking mating plate. The screw hole 225 is turned and the knob 227 is reversed, so that the locking screw 226 can be smoothly connected to the locking hole 212, further strengthening the connection stability between the card plate 211 and the card groove 222, and the installation is completed. When the belt needs to be disassembled for maintenance, it is not necessary to remove the entire reducer clutch body 1. Just rotate the limit plate 2 45 at the bottom of the pulley 41, so that the disassembly threaded column 44 and the disassembly threaded hole 43 can be rotated and separated, thereby disassembling the limit plate 2 45 at the bottom of the pulley 41, releasing the limit on the belt, so that the taut belt can be directly removed for maintenance.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
