Description

Technical Field

[0001] This utility model relates to the field of output shaft technology, specifically to a long-life output shaft. Background Technology

[0002] The output shaft is generally a transmission component for the output torque of a motor. In existing technology, the agitator in a pool, tank, or bucket needs to be driven by a motor, and the motor's output end is connected to the agitator via an output shaft. The motor is installed outside the tank, while the agitator is located inside. Therefore, the output shaft needs to pass through the side wall of the tank and rotatably connect to it. To achieve sealing and stable transmission, the output shaft usually rotates against the side wall of the tank. This friction causes wear on the output shaft, and prolonged wear will reduce its service life. Utility Model Content

[0003] To address the shortcomings of the existing technology, this invention proposes a long-life output shaft.

[0004] To achieve the above-mentioned technical effects, the present invention adopts the following solution:

[0005] A long-life output shaft includes a main shaft, a first flange, and a second flange. The first flange has a through hole at its center. The main shaft passes through the hole and is perpendicular to the first flange. The rear end of the main shaft is fixedly connected to the center of the second flange. Both the first and second flanges have several mounting holes. A sealing ring is provided on the inner wall of the through hole and is pressed against the main shaft. A sleeve protrudes from one side of the first flange facing the second flange and surrounds the main shaft. A bearing is fixedly installed inside the sleeve, and the main shaft is mounted on the bearing and rotates.

[0006] In a preferred embodiment, the front end of the spindle is provided with symmetrical cut planes on both sides, and a strip-shaped pin hole is provided through the spindle on the cut plane, the length of the pin hole being parallel to the length of the spindle.

[0007] In a preferred embodiment, the surface of the long-life output shaft is provided with a chromium plating layer.

[0008] In a preferred embodiment, the surface of the chromium plating layer is provided with a corrosion-resistant layer.

[0009] In a preferred embodiment, the corrosion-resistant layer comprises a polyethylene anti-corrosion coating layer and a nano-titanium organic anti-corrosion coating layer, wherein the polyethylene anti-corrosion coating layer is disposed on the surface of the chromium-plated layer, and the nano-titanium organic anti-corrosion coating layer is disposed on the surface of the chromium-plated layer.

[0010] Compared with existing technologies, the beneficial effects are:

[0011] This utility model has a simple structure and is easy to use. It is installed by attaching the first flange to the outer wall of the water tank and a sealing ring is provided in the central hole to achieve a seal. The main shaft rotates on the first flange through a bearing, and the second flange is used to connect to the output end of the motor. Thus, the rotation of the bearing replaces the friction rotation, reducing the wear of the main shaft and improving its service life. Attached Figure Description

The main shaft 1 passes through the through hole 4 and is perpendicular to the first flange 2. The rear end of the main shaft 1 is fixedly connected to the center of the second flange 3. Both the first flange 2 and the second flange 3 have a plurality of mounting holes 10. A sealing ring 5 is provided on the inner wall of the through hole 4. The sealing ring 5 is pressed against the main shaft 1. A sleeve 6 is provided around the main shaft 1, protruding from one side of the first flange 2 facing the second flange 3. A bearing 7 is fixedly installed inside the sleeve 6. The main shaft 1 is mounted on the bearing 7 and rotates.

[0017] The first flange 2 is installed on the outer wall of the water tank, and a sealing ring 5 is provided in the central hole 4 to achieve sealing. The main shaft 1 rotates on the first flange 2 through the bearing 7. The second flange 3 is used to connect to the output end of the motor.
