Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner bearings, and more precisely to a resin bearing for air conditioners with strong pressure resistance. Background Art

[0002] With the continuous development of air conditioner technology, the performance requirements for internal components of air conditioners are also getting higher and higher. Among them, as one of the important components inside the air conditioner, the performance of the bearing directly affects the operating efficiency and stability of the air conditioner.

[0003] Although traditional metal bearings have high strength and wear resistance, during long-term operation, due to metal fatigue and wear, their performance often deteriorates or even fails. Therefore, resin bearings are introduced. The key components such as the outer ring, inner ring, and balls of resin bearings are all made of resin materials. Bearings produced from resin materials have good wear resistance, corrosion resistance, and self-lubricating properties, making their compressive service life longer. There is a need for a resin bearing for air conditioners with good wear resistance and longer compressive strength service life.

[0004] In view of this, the utility model provides a resin bearing for air conditioners with strong pressure resistance. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned drawbacks and provide a resin bearing for air conditioners with good wear resistance and longer compressive strength service life.

[0006] Use a protective card board to protect the resin balls, enhance the service life of the resin bearing, and at the same time, the fixing ring enables the resin balls to rotate stably through the holes, reducing the friction of the resin bearing.

[0007] Therefore, the utility model provides a resin bearing for air conditioners with strong pressure resistance, including an outer ring of the resin bearing and an inner ring of the resin bearing. Grooves are provided on the inner wall of the outer ring and the outer wall of the inner ring. A plurality of balls are rotatably installed in the grooves between the outer ring and the inner ring. A stabilizing component for the stable rotation of the balls is installed on the outer surface of the balls. A protective component is installed between the outer ring and the inner ring, and the protective component is installed outside the balls to protect the balls.

[0008] As a further improvement of this technical solution, the stabilizing component includes a fixing ring installed between the outer ring and the inner ring. A plurality of holes adapted for the installation of the balls are provided on the outer surface of the fixing ring. The plurality of balls are installed inside the plurality of holes, so that the balls are installed inside the fixing ring and rotate evenly and stably in the grooves between the outer ring and the inner ring.

[0009] As a further improvement of the technical solution, the protection component includes a T-shaped groove opened on the inner wall of the outer ring and an inverted T-shaped groove opened on the outer wall of the inner ring. A protection card plate for blocking dust and water vapor is rotatably installed inside the T-shaped groove and the inverted T-shaped groove. A water flow groove for collecting water vapor is opened on the side wall of the inverted T-shaped groove. A leakage hole penetrating to the outside of the inner ring is opened on the inner wall of the water flow groove, and the leakage hole allows the water droplets collected in the water flow groove to flow out.

[0010] As a further improvement of the technical solution, there are two protection card plates. The two protection card plates are located on both sides of the ball, preventing dust and water vapor from entering the space between the outer ring and the inner ring and protecting the ball.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the resin bearing for air conditioner with strong anti-pressure, when the resin bearing is in use, the resin balls rotate stably in the resin outer ring and the resin inner ring through the fixing ring. And protection card plates are installed on both sides of the ball in the middle of the outer ring and the inner ring, which can rotate together with the ball to block the dust and water vapor outside the resin bearing. The blocked water vapor flows along the outer wall of the protection card plate into the water flow groove of the inner ring and flows out through the leakage hole, achieving the blocking of water vapor and dust, and enhancing the anti-pressure strength and service life of the resin bearing.

[0023] Although traditional metal bearings have high strength and wear resistance, during long-term operation, due to metal fatigue and wear, their performance often deteriorates or even fails. Therefore, resin bearings are introduced, and key components such as the outer ring, inner ring, and ball of the resin bearings are all made of resin materials. The bearings produced by resin materials have good wear resistance, corrosion resistance, and self-lubricating performance, making their compressive service life longer. There is a need for a resin bearing for air conditioners with good wear resistance and a longer compressive strength service life.

[0024] As Figures 1-4 shown, the device includes an outer ring 1 of the resin bearing and an inner ring 2 of the resin bearing. Rolling grooves are provided on the inner wall of the outer ring 1 and the outer wall of the inner ring 2. A plurality of balls 3 are rotatably installed in the rolling grooves between the outer ring 1 and the inner ring 2. A stabilizing component 4 for stably rotating the balls 3 is installed on the outer surface of the balls 3. A protective component 5 is installed between the outer ring 1 and the inner ring 2. The protective component 5 is installed outside the balls 3 to protect the balls 3.

[0025] First, the specific structure of the protective component 5 is disclosed. The protective component 5 includes a T-shaped groove 501 opened on the inner wall of the outer ring 1 and an inverted T-shaped groove 502 opened on the outer wall of the inner ring 2. A protective card plate 503 for blocking dust and water vapor is rotatably installed inside the T-shaped groove 501 and the inverted T-shaped groove 502. A water flow groove 504 for collecting water vapor is provided on the side wall of the inverted T-shaped groove 502. Leak holes 505 penetrating to the outside of the inner ring 2 are provided on the inner wall of the water flow groove 504, and the leak holes 505 allow the water droplets collected in the water flow groove 504 to flow out. Two protective card plates 503 are provided, and the two protective card plates 503 are located on both sides of the balls 3 to prevent dust and water vapor from entering between the outer ring 1 and the inner ring 2 and protect the balls 3.

[0026] The improvement of this embodiment lies in that: the protective card plate 503 is installed in the T-shaped groove 501 and the inverted T-shaped groove 502 opened on the outer ring 1 and the inner ring 2 to protect the balls 3 between the outer ring 1 and the inner ring 2. The protective card plate 503 can rotate in the T-shaped groove 501 and the inverted T-shaped groove 502 without affecting the rotation of the balls 3. Moreover, the water flow groove 504 opened on the inner wall of the inverted T-shaped groove 502 can collect the water vapor blocked by the protective card plate 503, so that the collected water vapor flows out through the leak holes 505 opened on the inner side wall of the water flow groove 504, achieving the blocking of water vapor and dust, preventing water vapor and dust from entering the resin balls 3 and causing damage to the resin balls 3.

[0027] Regarding the problem of how to stably rotate the resin balls 3 in the prior art, enhance the compressive strength and service life, therefore, Figure 4 The second embodiment of the present invention is shown.

[0028] The specific structure of the stabilizing component 4 is disclosed again. The stabilizing component 4 includes a fixing ring 401 installed between the outer ring 1 and the inner ring 2. A plurality of holes 402 adapted for installing the balls 3 are formed on the outer surface of the fixing ring 401. A plurality of balls 3 are installed inside the plurality of holes 402, so that the balls 3 are installed inside the fixing ring 401 and rotate stably and evenly in the rolling groove between the outer ring 1 and the inner ring 2.

[0029] The improvement of this embodiment lies in that: the fixing ring 401 fixes the positions of the plurality of balls 3 rotating between the outer ring 1 and the inner ring 2, stabilizes the rotation of the balls 3, reduces the friction of the resin balls 3, makes the resin balls 3 rotate more stably, and enhances the compressive strength and service life of the balls 3.

[0030] In summary, the working principle of this solution is as follows:

[0031] When using the resin bearing, the resin balls 3 rotate stably in the resin outer ring 1 and the resin inner ring 2 through the fixing ring 401. And protective clamping plates 503 are installed on both sides of the balls 3 between the outer ring 1 and the inner ring 2 and can rotate together with the balls 3 to block dust and water vapor outside the resin bearing. The blocked water vapor flows along the outer wall of the protective clamping plate 503 into the water flow groove 504 of the inner ring 2 and flows out through the leakage holes 505, achieving the blocking of water vapor and dust and enhancing the compressive strength and service life of the resin bearing.
