Abstract
Description
Technical Field
[0001] This utility model relates to the field of deceleration clutch technology, specifically a washing machine deceleration clutch equipped with a lubrication and dust prevention mechanism. Background Technology
[0002] As a core transmission component of fully automatic pulsator washing machines, the reduction clutch plays a crucial role in switching between two different operating states: low-speed forward and reverse rotation during washing and high-speed rotation during spin-drying. During washing, it operates at a low speed to gently agitate the pulsator, ensuring clothes are cleaned while preventing tangling. During spin-drying, it quickly switches to high-speed operation to expel water from the clothes. Its performance directly affects the washing machine's washing ratio, spin-drying rate, and operational stability.
[0003] For example, Chinese utility model patent application number 202121401806.3 discloses a washing machine reduction clutch with double internal gear rings. It uses a mounting block at the bottom of the inner wall of the protective shell to limit the clutch's position at both ends with locking bolts, ensuring stable clutch operation. A sleeve is installed between the mounting block and both sides of the inner wall of the protective shell, and a shock-absorbing spring is installed on the outer wall of the sleeve to prevent the device from moving during operation, thus avoiding damage to the clutch and increased maintenance costs. However, this device still has certain shortcomings.
[0004] The components inside the protective shell generate heat by rubbing against each other during operation. This makes it difficult to dissipate heat and lubricate the components. If the continuously generated heat cannot be dissipated in time, it will reduce the viscosity of the lubricating oil, accelerate its volatilization and oxidation, further weaken the lubrication effect, form a vicious cycle, and aggravate the wear of the components.
[0005] Therefore, we propose a washing machine deceleration clutch with a lubrication and dust prevention mechanism to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this utility model is to provide a washing machine deceleration clutch with a lubrication and dust prevention mechanism, so as to solve the problem mentioned in the background art that the components inside the protective shell on the market generate heat by rubbing against each other during operation, which is not convenient for heat dissipation and lubrication. If the continuously generated heat cannot be dissipated in time, it will reduce the viscosity of the lubricating oil, accelerate its volatilization and oxidation, further weaken the lubrication effect, form a vicious cycle, and aggravate the wear of the components.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a washing machine deceleration clutch with a lubrication and dust prevention mechanism, comprising a deceleration clutch body and a protective box.

Combined with the mechanical engagement of the snap-fit groove and the snap-fit block, the filter assembly can be "fixed with one insertion", enabling quick assembly and disassembly, which is more efficient than the traditional screw fixing method.
[0014] Preferably, the diameter of the sealing gasket is larger than the diameter of the oil delivery hole, and a rubber gasket is provided on the lower surface of the sealing gasket, and the sealing gasket and the rubber gasket are detachably connected.
[0015] The above structural design incorporates a sealing gasket with a diameter larger than the oil delivery hole, which, together with the rubber gasket on the lower surface, prevents lubricating oil leakage. The detachable structure facilitates regular replacement, prevents leakage during lubricating oil filling, and avoids contaminating the internal environment of the washing machine.
[0016] Preferably, the oil tank is equipped with guide strips inside, and a slider assembly is installed on the adjusting bolt. Connecting strips are installed on both the left and right sides of the slider assembly, and the connecting strips are connected to the sealing gasket.
[0017] With the above structural design, the guide bar and the slider assembly slide together, so that the sealing gasket moves smoothly when the adjusting bolt rotates.
[0018] Preferably, the lower surface of the slider assembly is provided with a groove, the guide strip is slidably connected to the slider assembly through the groove, and a sealing component is provided at the connection position between the adjusting bolt and the rear side of the oil tank.
[0019] With the above structural design, when the slider assembly moves under force, the guide bar plays a guiding role, so that the slider assembly will not deviate when it moves, and thus the connecting bar and sealing gasket connected to the slider assembly will not deviate when they move.
[0020] Preferably, the fixed base is provided with limit plates on both the front and rear sides, the limit plates are fixed on the reverse threaded rod, the reverse threaded rod is rotatably connected to the fixed base, the movable strip and the oil tank are connected by guide telescopic rods, and the snap-fit block snaps into the snap-fit groove on the filter screen assembly.
[0021] The above structural design, with the linkage between the reverse threaded rod and the guide telescopic rod, allows the locking blocks on both sides to move synchronously, and the guide telescopic rod provides a guiding function.

The diameter of the sealing gasket 11 is larger than the diameter of the oil supply hole 10, and a rubber gasket is provided on the lower surface of the sealing gasket 11. The sealing gasket 11 and the rubber gasket are detachably connected. The sealing gasket 11 blocks the oil supply hole 10. When lubrication of the reduction clutch body 1 is required, the sealing gasket 11 is adjusted to be away from the oil supply hole 10. The lubricating oil in the oil reservoir 9 is delivered to the reduction clutch body 1 through the oil supply hole 10. Under the vibration of the reduction clutch body 1 during operation, the lubricating oil coverage area is increased. An adjusting bolt 13 and a guide strip 12 are installed inside the oil reservoir 9. A slider assembly 14 is mounted on the adjusting bolt 13. Connecting strips 16 are mounted on both the left and right sides of the slider assembly 14. The connecting strips 16 are connected to the sealing gasket 11.

Then, it drives the snap-fit block 22 to snap into the snap-fit groove 8 of the filter assembly 7, thereby fixing the two filter assemblies 7 at the same time, which facilitates the quick assembly and disassembly of the filter assembly 7.
[0038] When lubrication of the reduction clutch body 1 is required, the sealing gasket 11 is adjusted to be away from the oil supply hole 10. The lubricating oil in the oil reservoir 9 is then delivered to the reduction clutch body 1 through the oil supply hole 10. Under the vibration of the reduction clutch body 1 during operation, the lubricating oil coverage area is increased. When adjusting the sealing gasket 11, rotating the adjusting bolt 13 moves the slider assembly 14 along the guide bar 12. The slider assembly 14 moves the connecting bar 16, which in turn moves the sealing gasket 11, thus opening and closing the oil supply hole 10, thereby completing a series of operations.
