Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a clothes dryer motor with a self-lubricating bearing. Background Art

[0002] As one of the core components of the dryer, the main function of the dryer motor is to drive the drying drum to rotate. Driven by the motor, the drying drum can rotate continuously and stably, ensuring that the clothes are evenly distributed in heat and fully turned during the drying process, thereby improving the drying efficiency and effect. The motor generates a rotational torque through the principle of electromagnetic induction to drive the drying drum to rotate. Whether it is an AC motor or a DC motor, its basic principle is to use the force exerted on the current in the magnetic field to generate rotational motion. During the operation of the dryer, the motor not only drives the drying drum to rotate, but also often works with components such as the fan to promote the circulation of hot air in the drying drum. The hot air can take away the moisture on the clothes and be discharged through the air outlet, thereby achieving rapid drying of the clothes.

[0003] During the use of the dryer, water vapor is bound to appear when drying clothes. The water vapor will come into contact with the motor through the gap of the dryer, causing rust on the motor, especially the bearings of the motor. After rust forms on the bearing surface, it will increase the friction coefficient of the bearing, making the motor face greater resistance when driving the drying drum to rotate. This will not only increase the energy consumption of the motor, but may also cause the motor to overheat. In addition, rust on the bearings will also cause increased noise when the motor is running. In order to increase the service life of the motor, a large amount of lubricating oil is often added to the bearings of the motor to isolate water vapor and reduce friction. However, during long-term use, as the use time increases, the lubricating oil will gradually age, and its lubricating performance will gradually decrease, and it may even become sticky or dry, unable to effectively wrap the bearings, so adjustments need to be made based on this.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 9 The present invention provides a technical solution: the bearing plays a vital role in the motor, which is used to support and position the rotating shaft 3. The bearing reduces the friction and wear during rotation through the rolling elements inside the bearing. When the clothes dryer is used, the clothes are dried, and the motor plays a role of rotating the clothes to improve the drying efficiency. In the clothes being dried, the water vapor is separated from the clothes. For the motor that has been used for a long time, it is corroded by water vapor and easily rusted. The rust on the outside of the motor has little effect on the motor, but the corrosion of the bearing used to reduce friction can easily affect the motor, increase the resistance to rotation, increase power consumption, cause the motor to overheat, and also increase noise. For this reason, it is necessary A clothes dryer motor with a self-lubricating bearing comprises two machine covers 1 which cooperate with each other, a rotating shaft 3 is rotatably installed in the machine covers 1, bearing covers 2 are fixed on the outsides of the two machine covers 1, a self-lubricating bearing assembly 4 is installed inside the bearing covers 2, the rotating shaft 3 passes through the two self-lubricating bearing assemblies 4, an outer protective cover 5 for sealing the self-lubricating bearing assembly 4 is fixed on the inner end of the bearing cover 2, lubricating oil for immersing the self-lubricating bearing assembly 4 is provided in the bearing cover 2, the lubricating oil is used to lubricate the bearing, and avoid being affected by water vapor during use, but the lubricating oil does not have a circulation function, and the lubricating oil becomes viscous after a long time, and will accumulate inside the bearing cover 2, so that the lubricating oil is separated from the bearing, and the bearing is easily affected by water vapor;

[0034] The self-lubricating bearing assembly 4 includes an outer ring 41 and an inner ring 42 forming a bearing. A driving layer 45 is fixed outside the inner ring 42 and rotates with the inner ring 42. The driving layer 45 is used to push the lubricating oil to circulate from the outside to the inside to achieve self-lubrication of the bearing. During the self-lubrication of the bearing, the bearing is protected from the influence of water vapor. In addition, when the viscosity of the lubricating oil changes, the lubricating oil can also circulate. The lubricating oil covers the bearing to the greatest extent, and the lubricating oil is prevented from accumulating directly in the bearing cover 2 as much as possible.

[0035] The inner ring 42 is fixedly sleeved with the rotating shaft 3, and the inner ring 42 is sleeved into the outer ring 41. The height of the inner ring 42 is greater than that of the outer ring 41, so that the two ends of the inner ring 42 are respectively against the inner wall of the bearing cover 2 and the outer protective cover 5. The gap generated by the outer side of the inner ring 42 and the inner side of the bearing cover 2 is used to fill the lubricating oil, so that the lubricating oil is limited. The outer ring 41 is clamped to the inner side of the bearing cover 2, and the outer side of the driving layer 45 is in contact with the outer protective cover 5. The side of the driving layer 45 is fixed with a fan plate 451 for driving the movement of the lubricating oil. When the rotating shaft 3 rotates, the fan plate 451 is driven to move to realize the driven movement of the lubricating oil. During the operation of the motor, the lubricating oil is always circulated to keep the bearing covered. Water vapor is also generated during the operation of the dryer, so that the generated water vapor is prevented from entering the bearing and the bearing is prevented from rusting.

[0036] A flow channel 43 distributed in a circular pattern is provided on the outer side of the outer ring 41, and a flow port 44 is provided on the inner wall of the flow channel 43. The flow port 44 is connected to the inner side of the outer ring 41. The fan plate 451 rotates to drive the lubricating oil to move from the outside to the inside of the outer ring 41. During the circulation of the lubricating oil, the lubricating oil moves from the outside to the inside of the outer ring 41, directly contacting the ball, roller or sliding surface of the bearing, so that the lubricating oil covers the internal structure of the bearing and isolates the water vapor.

[0037] The fan plate 451 is a metal sheet. During the rotation process, the metal sheet is easier to rotate and lighter. The fan plate 451 is inclined and extends from the upper end of the inner ring 42 to the upper end of the outer ring 41 to push outward the lubricating oil moving upward from between the inner ring 42 and the outer ring 41.

[0038] Among them, the fan plate 451 is inclined, which can interact with the lubricating oil more effectively when rotating. The inclined surface will form an angle with the water, and this angle enables the fan plate 451 to generate an outward component when pushing the lubricating oil. The main thrust of the inclined fan plate 451 comes from its inclined design, but the rotation itself will also generate a certain centrifugal force. Centrifugal force is a virtual force generated when an object moves in a circular motion. It points in the opposite direction of the center of the circle, that is, away from the center of the circle. In this scenario, the centrifugal force will assist the fan plate 451 in pushing the lubricating oil to the outside.

[0039] The upper and lower sides of the fan plate 451 are in contact with the outer protective cover 5 and the outer ring 41 respectively, one side of the inner ring 42 is in contact with the outer protective cover 5, and the other side is in contact with the end of the bearing cover 2 to prevent the lubricating oil from leaking out. The upper and lower sides of the fan plate 451 are blocked, so that during the rotation of the fan plate 451, the fan plate 451 pushes the lubricating oil outward to achieve lubrication circulation and avoid the fan plate 451 from generating gaps and causing the lubricating oil to leak into the gaps.

[0040] The self-lubricating bearing assembly 4 also includes a limit member 46 that constitutes a lubricating oil circulation channel. The limit member 46 is located between the outer ring 41 and the bearing cover 2 and is used to limit the outer ring 41. One end of the limit member 46 is connected to the flow channel 43, and the other end is connected to the outside of the outer ring 41. The function of the limit member 46 is to limit the outer ring 41 and connect the flow channel 43 with the outside during the limiting process, so that the fan plate 451 pushes the lubricating oil into the flow channel 43.

[0041] The limiting member 46 includes a semi-shaft body 461 and a semi-circle layer 462. The semi-circle layer 462 is located outside the semi-shaft body 461. The two are integrally arranged. The height of the semi-circle layer 462 is less than that of the semi-shaft body 461. The semi-shaft body 461 has an infusion port 463 extending from bottom to top. One half of the infusion port 463 penetrates the semi-circle layer 462, and the other half extends to the inside of the semi-shaft body 461. The limiting member 46 limits the outer ring 41 and also delivers lubricating oil through the infusion port 463. When the bearing is installed, the bearing is directly embedded in the bearing cover 2, and the bearing is limited by the limiting member 46.

[0042] An installation cavity 432 is downwardly opened between the outer ring 41 and the bearing cover 2, and an inner extension hole 431 is extended downwardly from the inner wall of the installation cavity 432, and the lower end of the inner extension hole 431 is connected with the flow channel 43, and an outer cavity 433 connected with the installation cavity 432 is downwardly opened on the bearing cover 2, and the outer cavity 433 has the same diameter as the installation cavity 432, and the axes of the outer cavity 433, the installation cavity 432 and the inner extension hole 431 coincide with each other, the lower end of the semi-axle body 461 and the semi-circle layer 462 are embedded in the installation cavity 432, and the upper half of the semi-axle body 461 is embedded in the outer cavity 433, and the semi-axle body 461 is fixed to the bearing cover 2 by bolts, and the infusion port 463 is connected with the inner extension hole 431, so as to fix the limit member 46 and the bearing cover 2, and at the same time, the upper end of the bearing cover 2 is also flush with the upper end of the semi-axle body 461, so that the lubricating oil enters the inner extension hole 431 during the movement of the fan plate 451.

[0043] Half of the mounting cavity 432 and the inner extension hole 431 are provided on the outer ring 41, and the other half are provided on the bearing cover 2. The two halves of the mounting cavity 432 and the inner extension hole 431 are respectively located on the outer ring 41 and the bearing cover 2, so that the diameters of the mounting cavity 432 and the inner extension hole 431 can be relatively large, so that the lubricating oil can move more smoothly. At the same time, when the self-lubricating bearing assembly 4 is disassembled, the mounting cavity 432 and the inner extension hole 431 are divided into two halves, and the two halves of the mounting cavity 432 and the inner extension hole 431 are convenient for direct cleaning.

[0044] A filter layer is fixed inside the infusion port 463 , and the filter layer filters the lubricating oil in motion, so that the lubricating oil entering between the outer ring 41 and the inner ring 42 has high cleanliness, thereby reducing the impact on the moving bearing.

[0045] Working principle of the present invention: During the operation of the motor of the clothes dryer, the bearing serves as the support point of the rotating parts in the motor. The bearing usually uses structures such as balls, rollers or sliding surfaces. The design of these structures can greatly reduce the direct contact area between the rotating parts and the bearing, thereby reducing friction and wear. The inner ring 42 of the bearing is usually fixedly connected to the rotating parts of the motor and rotates with it. The outer ring 41 is usually installed on the stationary parts of the motor and remains stationary. This design allows the rotating parts to rotate smoothly in the bearing while the outer ring 41 provides stable support.

[0046] Based on the function of the above-mentioned bearing, during the rotation of the inner ring 42, the driving layer 45 and the fan plate 451 are driven to rotate, and the inside of the bearing cover 2 is filled with lubricating oil, which is equivalent to the bearing being partially immersed in the lubricating oil. When the fan plate 451 rotates, the local lubricating oil moves outward, passes through the limiter 46, and enters the flow channel 43, and then enters between the outer ring 41 and the inner ring 42 from the flow port 44, lubricating and coating the ball, roller or sliding surface structures of the bearing, reducing friction to the greatest extent, and keeping water vapor isolated. The excess lubricating oil moves outward from between the outer ring 41 and the inner ring 42, and is pushed by the fan plate 451, so that the lubricating oil is continuously and repeatedly lubricated. It also has the advantages of long service life, good wear resistance, and low friction coefficient, which can further reduce the failure rate and maintenance cost of the motor.

[0047] In addition, the flow port 44 extends horizontally between the outer ring 41 and the inner ring 42. The structures such as the balls, rollers or sliding surfaces between the outer ring 41 and the inner ring 42 rotate with the rotation of the rotating shaft 3, and the lubricating oil in the flow port 44 continuously overflows, so that the structures such as the balls, rollers or sliding surfaces between the outer ring 41 and the inner ring 42 are covered with the lubricating oil, so that every place is lubricated to avoid rust.

[0048] Under the action of the semi-axle body 461, the outer ring 41 is limited to prevent it from rotating. In addition, the circulating lubricating oil needs to move from the filling port 463, and the filling port 463 has a filter screen. The lubricating oil is filtered through the filter screen, which can filter local metal particles or pollutants in the lubricating oil, improve the cleanliness of the lubricating oil to a certain extent, reduce impurities and pollutants therein, such as metal particles, dust, etc., and avoid entering between the outer ring 41 and the inner ring 42, thereby reducing the impact on the bearing. When the filtering effect of the limiter 46 is not good, the semi-axle body 461 and the semi-ring layer 462 can be disassembled, cleaned or replaced to keep the lubricating oil in the best state.

[0049] After long-term use, the lubricating oil is affected by factors such as oxidation and thermal degradation, resulting in a decrease in performance and an increase in viscosity. The increase in viscosity can prevent the lubricating oil from leaking out of the gaps. In addition, since the lubricating oil needs to circulate, the amount of lubricating oil is relatively large. Therefore, after the performance of the lubricating oil decreases, it can still adhere to the structures such as the balls, rollers or sliding surfaces between the outer ring 41 and the inner ring 42 to avoid separation from the bearing, thereby avoiding further contact between water vapor and the bearing, thereby maximizing the service life.
