For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0037] See also Figures 1 to 6 The present disclosure provides a cleaning equipment gearbox mechanism, including a motor 1 and a gearbox housing 3. The motor 1 refers to an electric motor used to drive the cleaning equipment gearbox mechanism. Its function is to drive the movement of the gearbox mechanism by converting electrical energy into mechanical energy, thereby realizing the cleaning function of the cleaning equipment. Specifically, the motor of the cleaning equipment gearbox mechanism drives the movement of cleaning components such as brushes, scrapers, and vacuum cleaners by rotating the gears in the gearbox mechanism, thereby realizing the cleaning of surfaces such as the ground, walls, and windows.

[0038] One end of the output shaft of the motor 1 is provided with a first vibration-damping cotton 2 for reducing vibration and noise. The vibration-damping cotton is a material used to reduce vibration and noise of a gear box mechanism of a cleaning device.

[0039] The main function of vibration damping cotton is to reduce the vibration and noise generated by the gearbox mechanism during operation, protect the normal operation of the mechanism and extend its service life. It can absorb and disperse the impact force and vibration transmitted by the gear, effectively reduce the noise level and provide a smoother operating environment.

[0040] The material of vibration damping cotton can be various materials, such as polyurethane, silicone, rubber, etc. Different materials have different characteristics, and the appropriate vibration damping cotton material can be selected according to the specific application requirements.

[0041] The first vibration-damping cotton 2 is provided with a slot for convenient insertion into one end of the motor 1, and the gear box housing 3 is provided with a second vibration-damping cotton 13 for reducing vibration and noise of the motor 1. The other end of the second vibration-damping cotton 13 is provided with a round hole that can just fit into the protrusion on the gear box housing 3, and the side surface of the second vibration-damping cotton 13 is provided with a fixed bearing 6, which is usually a rolling bearing, such as a ball bearing or a roller bearing.

[0042] The function of fixed bearings is to support and position rotating parts so that they can run smoothly and bear the axial and radial loads from the gear transmission. They improve the efficiency of the gearbox by reducing friction and rotational resistance and reduce energy consumption. Fixed bearings can also improve the operating stability and comfort of the equipment by reducing vibration and noise. In addition, fixed bearings can prevent relative movement of the internal parts of the gearbox and ensure accurate matching between gears, thereby ensuring the accuracy and reliability of the transmission.

[0043] A follower bearing 11 is arranged on the upper cover 12 of the gearbox, and one end of the driven shaft 7 is connected to the follower bearing 11 after being sleeved with the fixed bearing 6. The follower bearing 11 is a special bearing, usually called a follower bearing or an adaptive bearing. Its function is to support and rotate the gear shaft in the gearbox mechanism.

[0044] The follower bearing can withstand the high-speed rotation and large torque generated in the gearbox, and can adapt to the deviation and deformation between bearings. Its design and working principle enable the gear shaft to maintain stable operation under high-speed rotation and large load, and reduce the wear and friction between the gear shaft and the bearing.

[0045] The main function of the follower bearing is to reduce the contact pressure and friction between the gear shaft and the bearing, reduce energy loss and heat generation, and improve the working efficiency and life of the gearbox mechanism. At the same time, the follower bearing can also reduce vibration and noise, and improve the running smoothness and stability of the gearbox mechanism.

[0046] The other end of the driven shaft 7 is sleeved with a driving fastener 8, which is a part used to connect and fix the gearbox with a drive motor or other power source. It is commonly in the form of bolts, screws or pins. The driven shaft 7 is a shaft in the gearbox, and its function is to transmit power and torque, and convert the input speed and torque of the gearbox into output speed and torque. The driven shaft is usually connected to the output shaft of the gearbox, and transmits the output rotational force of the gearbox to the working parts of the cleaning equipment, such as brushes, scrapers or nozzles, so as to achieve normal operation of the cleaning equipment.

[0047] The function of the drive fastener is to firmly connect the gearbox and the drive source to ensure the transmission efficiency and operation stability between them. It bears the torque and force transmitted by the gearbox, so that the drive source can effectively transmit power to the gearbox, thereby promoting the normal operation of the cleaning equipment.

[0048] Drive fasteners are generally made of high-strength metal materials, such as carbon steel, stainless steel, etc. These materials have good strength and corrosion resistance, can withstand high torque and force, and ensure a firm and reliable connection.

[0049] The driven synchronous wheel 9 is provided on the gear box housing 3. The driven synchronous wheel 9 is movably sleeved with a belt retaining ring 10 which can prevent the synchronous belt 5 from falling off during movement. The driven synchronous wheel 9 is meshed and sleeved with one end of the synchronous belt 5. The synchronous belt 5 is a special transmission belt which transmits the transmission force through the engagement of teeth. Its function is to transmit the power of the driving wheel to the driven wheel to realize the normal operation of the gear box.

[0050] The main function of the synchronous belt is to accurately transmit the power of the driving wheel to the driven wheel, ensuring that the various components of the gearbox mechanism work together. In addition, the teeth on the synchronous belt are tightly engaged, which can ensure that the speeds of the driving wheel and the driven wheel are completely consistent, ensuring the stable operation of the gearbox mechanism. Then the synchronous belt has a certain elasticity and buffering performance, which can reduce the impact and vibration during gear transmission and protect the components of the gearbox mechanism. Finally, by replacing different specifications of the synchronous belt, the transmission ratio of the gearbox mechanism can be adjusted to meet different work requirements.

[0051] The gearbox housing 3 is connected to the gearbox cover 12, which is a protective cover covering the top of the gearbox. Its functions mainly include the following aspects: the gearbox cover can prevent external debris, dust, water, etc. from entering the interior of the gearbox, thereby protecting gears, bearings and other components from contamination and damage. The gearbox cover usually adopts a sealing structure to ensure that the lubricating oil inside the gearbox does not leak out and prevent external impurities from entering the interior of the gearbox, thereby maintaining the stability and normal operation of the gearbox. Some gearbox covers are designed with heat dissipation holes or cooling fans. By increasing the heat dissipation area or using the wind power of the fan, the temperature inside the gearbox can be effectively reduced to prevent gears, bearings and other components from being damaged due to overheating.

[0052] The upper cover 12 of the gearbox is provided with a through hole that can be rotatably connected to the main drive synchronous wheel 4. The upper cover 12 of the gearbox is provided with the main drive synchronous wheel 4, which is an important component of the gearbox. Its function is to transmit the power of the driving shaft to the driven shaft to realize the drive of the gearbox. The main drive synchronous wheel is usually made of a large gear and can realize power transmission by meshing with other gears. Its function is to provide power output of the gearbox and ensure the synchronous operation between different gears so that the gearbox can work stably.

[0053] One end of the main drive synchronous wheel 4 is provided with a block that can clamp the perforation, and the other end of the synchronous belt 5 is meshed and sleeved with the main drive synchronous wheel 4. The output shaft of the motor 1 movably penetrates the gear box shell 3 and is fixedly sleeved with the main drive synchronous wheel 4.

[0054] like Figure 1 and Figure 5 As shown, a protrusion is provided on the outer wall of the gear box shell 3, an arc-shaped groove that can clamp the protrusion is provided at one end of the second vibration-damping cotton 13, the outer wall of the gear box shell 3 is fixedly connected to the protrusion corresponding to the connecting plate, and the outer wall of the gear box shell 3 is fixedly connected to a plurality of arc-shaped connecting blocks, and the arc-shaped connecting blocks are all provided with through holes for convenient installation and connection.

[0055] like Figure 2 and Figure 5 As shown, the outer wall of the gear box upper cover 12 is fixedly connected to a clamping mechanism that is convenient for connecting to the gear box shell 3. The clamping mechanism includes a connecting plate connected to the gear box upper cover 12. The connecting plate is provided with a clamping groove connected to the gear box shell 3. The gear box upper cover 12 is provided with an elliptical protrusion that can resist the rotating mechanism to make it more stable. The gear box upper cover 12 is provided with a rectangular protrusion that can resist the rotating mechanism to make it more stable.

[0056] Working principle: When the cleaning equipment needs to use the gear box mechanism, one side of the head is fixed to the motor 1 through the first vibration-damping cotton 2 to prevent resonance, vibration, noise and abnormal sound during the operation of the motor 1. The output shaft end of the motor 1 is pressed into the main driving synchronous wheel 4 by interference fit. The tail of the gear box shell 3 on the same side is provided with a fixed bearing 6. The top of the driven shaft 7 passing through the fixed bearing 6 is connected with a driving fastener 8. A driven synchronous wheel 9 is fixed to the middle of the other side of the driven shaft 7. A synchronous belt 5 is connected between the main driving synchronous wheel 4 and the driven synchronous wheel 9. A belt retaining ring 10 is fixed on the driven synchronous wheel 9 to prevent the synchronous belt 5 from falling off during movement. The tail of the driven shaft 7 is assembled with the gear box upper cover 12 and the gear box shell 3, and is fitted into the follower bearing 11 fixed on the gear box upper cover 12, and is inserted into the driven shaft 7 at the same time as the fixed bearing 6 on the gear box shell 3, thereby achieving double The smooth operation of the shaft brought by the bearing solves the problem of radial load and axial load. When the gear box mechanism of this cleaning equipment is in operation, the motor 1 drives the main driving synchronous wheel 4 to connect and rotate with the driven synchronous wheel 9 through the synchronous belt 5. The driven shaft 7 fixed on the driven synchronous wheel 9 and the driving fastener 8 pass through the double bearings of the fixed bearing 6 and the follower bearing 11 to rotate efficiently and stably. The second vibration-damping cotton on the gear box shell 3 plays a role in eliminating resonance, jitter, noise and abnormal sound when the gear box mechanism of this cleaning equipment is fixed with other mechanisms. The gear box mechanism of this cleaning equipment eliminates resonance, jitter, noise and abnormal sound, and can bring smooth operation of the shaft of the double bearings, solves the problem of radial load and axial load, thereby achieving efficient and stable operation, so that more cleaning equipment products can work stably, efficiently, with low maintenance and low noise.
