Description

Technical Field

[0001] This utility model relates to the field of dehumidifiers, and in particular to a bearing anti-loosening device for an adsorption impeller. Background Technology

[0002] Rotary dehumidifiers consist of a dehumidifying rotor that adjusts the temperature and humidity of the air passing through it. Currently, the design of dehumidifying rotors uses a traditional method of machining bearing sleeves and ensuring a tight fit to prevent loosening. Once the bearing is engaged with the sleeve, it rotates for an extended period at the center of the rotor. However, because the dehumidifying rotor operates under high pressure and high humidity, the bearing is prone to loosening, making future replacement and maintenance inconvenient and compromising the precision of the rotor frame. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a bearing anti-loosening device for an adsorption wheel that prevents bearing loosening and improves the accuracy of use.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a bearing anti-loosening device for an adsorption wheel, comprising a base, a bearing, an active set screw, and a driven set screw. The bearing is disposed in the base, and a first moving channel is provided in the base corresponding to the side of the bearing. A second moving channel communicating with the first moving channel is provided on the upper side of the base. The active set screw is movably disposed in the second moving channel, and the driven set screw is movably disposed in the first moving channel. The active set screw approaches and pushes the driven set screw to move along the first moving channel along the second moving channel, and the driven set screw abuts against the side of the bearing.

[0005] Furthermore, the length direction of the first moving channel is perpendicular to the length direction of the second moving channel.

[0006] Furthermore, a pressing slope is provided on the side of the driven set screw opposite to the active set screw, and one end of the active set screw abuts against the pressing slope.

[0007] Furthermore, the driven set screw has a tapered end near the active set screw.

[0008] Furthermore, the end of the active setter near the driven setter is tapered.

[0009] Furthermore, it also includes a retaining ring, wherein the base has a recessed mounting groove on the upper side corresponding to the bearing, and the retaining ring is engaged in the mounting groove and abuts against the upper side of the bearing.

[0010] Furthermore, the base is provided with an annular boss that abuts against the lower side of the bearing.

[0011] Furthermore, the active set screw, the driven set screw, the first moving channel, and the second moving channel are all provided in multiples along the circumference of the base.

[0012] Furthermore, the first movable channel connects the inner side of the base and the outer side of the base.

[0013] Furthermore, the active set screw is threadedly connected to the second moving channel.

[0014] The beneficial effects of this invention are as follows: When the bearing is arranged, it is placed inside the base, and then the active set screw moves along the second moving channel to drive the driven set screw to move along the first moving channel, thereby pressing against the side of the bearing and fixing it to prevent loosening. This design avoids the bearing loosening that can easily occur under the high pressure and high humidity conditions of the dehumidifier's adsorption rotor, effectively ensuring bearing stability and guaranteeing the rotor's accuracy.

[0021] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] Please refer to Figures 1 to 4An anti-loosening device for a bearing in an adsorption wheel includes a base 1, a bearing 2, an active set screw 3, and a driven set screw 4. The bearing 2 is disposed inside the base 1. A first moving channel 11 is provided inside the base 1 corresponding to the side of the bearing 2. A second moving channel 12 communicating with the first moving channel 11 is provided on the upper side of the base 1. The active set screw 3 is movably disposed in the second moving channel 12, and the driven set screw 4 is movably disposed in the first moving channel 11. The active set screw 3 approaches and pushes the driven set screw 4 along the second moving channel 12 to move along the first moving channel 11, and the driven set screw 4 abuts against the side of the bearing 2.

[0023] As can be seen from the above description, the beneficial effects of this utility model are as follows: When the bearing 2 is arranged, it is placed inside the base 1, and then the active set screw 3 moves along the second moving channel 12 to drive the driven set screw 4 to move along the first moving channel 11, thereby pressing against the side of the bearing 2 and fixing it to prevent loosening. This design avoids the situation where the bearing 2 is prone to loosening under the high pressure and high humidity conditions of the dehumidifier's adsorption wheel, effectively ensuring the stability of the bearing 2 and ensuring the accuracy of the wheel.

[0024] Furthermore, the length direction of the first moving channel 11 is perpendicular to the length direction of the second moving channel 12.

[0025] As can be seen from the above description, the design of the first moving channel 11 and the second moving channel 12 along their length direction ensures that the driven set screw 4 is driven by the movement of the active set screw 3 within a short moving stroke, thereby achieving the anti-loosening fixation of the bearing 2.

[0026] Furthermore, the driven set screw 4 is provided with a pressing slope on the side opposite to the active set screw 3, and one end of the active set screw 3 abuts against the pressing slope.

[0027] As can be seen from the above description, by designing the pressing slope of the driven set screw 4, the lateral movement of the driven set screw 4 is achieved when the active set screw 3 presses against the driven set screw 4.

[0028] Furthermore, the driven set screw 4 is tapered at the end near the active set screw 3.

[0029] As can be seen from the above description, the tapered design of the driven set screw 4 avoids the limitation of the installation angle of the driven set screw 4 by the single-sided inclined surface.

[0030] Furthermore, the active setter 3 is tapered at the end near the driven setter 4.

[0031] As can be seen from the above description, the tapered design of the active set screw 3 can cooperate with the tapered end of the driven set screw 4 to achieve rapid pressing and pushing, ensuring that the driven set screw 4 presses and fixes the side of the bearing 2.

[0032] Furthermore, it also includes a retaining spring 5. The base 1 has a recessed mounting groove 13 on the upper side corresponding to the bearing 2. The retaining spring 5 is engaged in the mounting groove 13 and abuts against the upper side of the bearing 2.

[0033] As can be seen from the above description, by configuring the retaining ring 5 in the mounting groove 13 of the base 1, it can press and fix the upper side of the bearing 2 to prevent it from loosening and falling out.

[0034] Furthermore, the base 1 is provided with an annular boss 14 that abuts against the lower side of the bearing 2.

[0035] As can be seen from the above description, the annular boss 14 in the base 1 can serve as a lower limit when the bearing 2 is arranged, and it can also cooperate with the snap ring 5 to press and fix the bearing 2 in the vertical direction, thereby improving the anti-loosening performance.

[0036] Furthermore, the active set screw 3, the driven set screw 4, the first moving channel 11, and the second moving channel 12 are all provided in multiple directions along the circumference of the base 1.

[0037] As can be seen from the above description, the design of multiple active set screws 3, driven set screws 4, first moving channel 11 and second moving channel 12 further ensures the lateral pressure fixation of the bearing 2, realizing the anti-loosening design.

[0038] Furthermore, the first movable channel 11 connects the inner side of the base 1 and the outer side of the base 1.

[0039] As can be seen from the above description, the driven set screw 4 and bearing 2 can be easily disassembled and assembled by the first moving channel 11 located on the inner and outer sides of the base 1.

[0040] Furthermore, the active set screw 3 is threadedly connected to the second moving channel 12.

[0041] As can be seen from the above description, the movement and fixation of the active set screw 3 can be realized through the threaded connection between the active set screw 3 and the second moving channel 12; after the driven set screw 4 is pushed into the bearing 2, a stable structure can be formed by the fixation of the active set screw 3 to ensure the anti-loosening effect.

[0042] Please refer to Figures 1 to 4 Embodiment 1 of this utility model is as follows:

[0043] An anti-loosening device for a bearing 2 of an adsorption wheel includes a base 1, a bearing 2, an active set screw 3, a driven set screw 4, and a retaining ring 5.

[0044] The bearing 2 is located inside the base 1. The base 1 has a recessed mounting groove 13 on the upper side corresponding to the bearing 2, and the retaining spring 5 is engaged in the mounting groove 13 and abuts against the upper side of the bearing 2; the base 1 has an annular boss 14 that abuts against the lower side of the bearing 2.

[0045] The base 1 has a first moving channel 11 corresponding to the side of the bearing 2, which connects the inner side and the outer side of the base 1. The upper side of the base 1 has a second moving channel 12 that communicates with the first moving channel 11. The active set screw 3 is movably disposed in the second moving channel 12 through a threaded engagement with the second moving channel 12, and the driven set screw 4 is movably disposed in the first moving channel 11. The active set screw 3 moves closer to the driven set screw 4 along the second moving channel 12 and pushes the driven set screw 4 to move along the first moving channel 11, and the driven set screw 4 abuts against the side of the bearing 2.

[0046] Specifically, the length direction of the first moving channel 11 is perpendicular to the side of the bearing 2, while the length direction of the second moving channel 12 is perpendicular to the length direction of the first moving channel 11.

[0047] To ensure that the active set screw 3 can move and drive the driven set screw 4 during the jacking process, the end of the active set screw 3 is designed to be tapered. Similarly, the end of the driven set screw 4 is designed to be tapered. The cooperation of the two tapered ends achieves the pressing and fixing of the side of the bearing 2.

[0048] Optionally, multiple sets of active set screws 3, driven set screws 4, first moving channel 11 and second moving channel 12 can be designed around the base 1 to press and fix the side of the bearing 2 in multiple directions.

[0049] In summary, the anti-loosening device for the adsorption rotor provided by this utility model involves placing the bearing inside the base during bearing arrangement. Then, the active set screw moves along the second moving channel, driving the driven set screw to move along the first moving channel, thereby pressing against the side of the bearing and fixing it to prevent loosening. This design avoids the bearing loosening that can easily occur under the high pressure and high humidity conditions of the dehumidifier's adsorption rotor, effectively ensuring bearing stability and guaranteeing the rotor's operational accuracy.
