[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Bearings are generally composed of an outer ring, an inner ring, and steel balls. In the heat treatment process of the steel balls, in order to change the internal structure and properties of the steel balls and improve their strength, hardness, wear resistance, fatigue strength, and toughness, it is usually necessary to quench the steel balls in water after heating them to a certain temperature.

[0003] Chinese patent document CN211227244 discloses a heat treatment quenching device for processing steel balls for wind turbine bearings, including a cooling box. A support base is fixedly connected to the bottom of the side of the cooling box, and a support plate is fixedly connected to the top of the cooling box. A movable frame is movably sleeved inside the support plate. A mesh box is fixedly connected to the bottom of the movable frame. A water outlet funnel is fixedly installed at the bottom of the cooling box. A water outlet pipe is fixedly connected inside the water outlet funnel, and a valve is fixedly installed outside the water outlet pipe.

[0004] The current device requires manual placement of steel balls into the quenching chamber for quenching and then removal, which is inefficient. Furthermore, the device cannot reuse water, and the water temperature will rise after a period of use, affecting the quenching quality of the steel balls. Therefore, it is necessary to develop a quenching device for the production of wind turbine bearing balls that improves the quenching quality and efficiency of wind turbine bearing steel balls.

[0020] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-3 The present invention provides a technical solution: a quenching device for producing ball bearings of wind turbine bearings, comprising a housing 1, a cavity 2 formed inside the housing 1, a rotating cylinder 3 rotatably connected inside the cavity 2, the two ends of the rotating cylinder 3 being closed, and three cavities 4 being formed inside the rotating cylinder 3. The cross-sectional shape of the three cavities 4 along the axis of the rotating cylinder 3 is fan-shaped, and the three cavities 4 are evenly distributed in a circle with the axis of the rotating cylinder 3 as the center. The three cavities 4 all serve as cavities for quenching steel balls.

[0022] The side wall of the three cavities 2 4 away from the axis of the rotating drum 3 has a feed port 5. The feed port 5 is used to allow the steel balls to enter the cavity 2 4, and also to discharge water.

[0023] A partition 6 is provided between each of the two adjacent cavities 4, and the feed inlet 5 is located on the side of the partition 6 near the cavity 4 in a counterclockwise direction.

[0024] One end of the rotating drum 3 along the axial direction passes through the housing 1. A gear ring 7 is fitted on the outer wall of the end of the rotating drum 3 that passes through the housing 1. A drive motor 8 is fixedly connected to the outer wall of the housing 1. A gear 9 is fixedly connected to the output shaft of the drive motor 8. The gear 9 meshes with the gear of the gear ring 7, and the rotating drum 3 is driven to rotate by the drive motor 8.

[0025] The upper side of the housing 1 has a feed inlet 10. After the rotating drum 3 rotates, there is always a feed inlet 5 in the cavity 2 4 that is connected to the feed inlet 10. The steel ball enters the cavity 2 4 through the feed inlet 10 and the feed inlet 5 in sequence.

[0026] A rubber baffle (not shown in the figure) is installed at the edge of the feed inlet 10 facing the cavity 2 to block the gap between the feed inlet 10 and the outer wall of the rotating drum 3, so as to prevent the steel balls from falling into the cavity 2 during the process of entering the cavity 4.

[0027] A first filter screen 11 is provided inside the cavity 2. The first filter screen 11 is inclined and the mesh size of the first filter screen 11 is smaller than the diameter of the steel ball.

[0028] The first filter screen 11 is located below the rotating drum 3. The first filter screen 11 is tilted so that the water and steel ball in the cavity 2 4 are released from the inlet 5 under the action of gravity. The steel ball and water are separated by the first filter screen 11. The separated water accumulates in the cavity 1 2 and is located below the first filter screen 11.

[0029] The inner wall of cavity 12 has a discharge port 12, which is located on the downward inclined side of the first filter screen 11. The lower end of the discharge port 12 is fixedly connected to the first filter screen 11. The steel ball is moved out of the box 1 through the discharge port 12 on the first filter screen 11.

[0030] A water inlet pipe 13 is installed inside cavity 2. The water inlet pipe 13 is located on the side away from the first filter screen 11 relative to the center of the rotating drum 3. The water inlet pipe 13 is horizontally installed and fixedly connected to the box body 1. The output end of the water inlet pipe 13 passes through the box body 1 and is connected to a water chiller. The water chiller is a conventional technology. The output end of the water chiller passes through the box body 1 and is connected to the lower side of cavity 2. Water for quenching is stored in the lower part of cavity 2. Cold water is flushed into cavity 4 through the water inlet pipe 13 to quench the steel ball.

[0031] A second filter 14 is provided below the first filter 11. The second filter 14 is horizontally positioned and is higher than the highest water level of the cavity 2.

[0032] The second filter screen 14 has a double-layer filter screen. The upper layer of the filter screen has a mesh diameter of 0.4 mm and is used to filter large particles of oxide scale and debris. The lower layer of the filter screen has a mesh diameter of 0.15 mm and is used to filter fine particles.

[0033] The inner wall of cavity 2 has an installation port. The second filter 14 is installed in cavity 2 through the installation port. At the same time, the second filter 14 can be removed and replaced through the installation port.

[0034] In this embodiment, the drive motor 8 drives the rotating drum 3 to rotate, so that the feed port 5 of any cavity 4 of the rotating drum 3 rotates to the side close to the water inlet pipe 13, and the water inlet pipe 13 flushes an appropriate amount of cold water into the cavity 4.

[0035] After the cold water is poured in, the drive motor 8 is started again, so that the cavity 2 4 containing cold water rotates to the side close to the feed port 10 under the rotation of the rotating drum 3, so that the feed port 5 of the cavity 2 4 is connected to the feed port 10. The steel balls that need to be quenched are poured in from the feed port 10 and enter the cavity 2 4 through the feed port 5, and the cold water quenches the steel balls.

[0036] Based on the quenching time of the steel balls by cold water, during this period, cold water is flushed into another cavity 4 by the water inlet pipe 13 to prepare for the quenching of the next group of steel balls.

[0037] After the steel balls are quenched in cold water, the drive motor 8 is started to continue to drive the rotating drum 3 to rotate counterclockwise, so that the cavity 4 containing the steel balls rotates to the side closer to the first filter component. Under the action of gravity, the steel balls and water in the cavity 4 are released from the feed port 5.

[0038] The first filter screen 11 separates the steel balls from the water. The separated steel balls roll out of the box 1 from the discharge port 12 under the action of gravity and are collected and transported manually or by conveyor belt.

[0039] The separated water, carrying the debris generated after quenching, is filtered by the second filter screen 14 to separate the debris from the water. The filtered water is stored at the bottom of cavity 2. The water chiller extracts the water from cavity 2 and cools and regulates the water. The cooled water is pumped by the water chiller's own pump to the water inlet pipe 13 to continue participating in the quenching of the steel ball, thus realizing the recycling of water.
