[0028] Example one

[0029] As Figure 1 and Figure 3As shown, the oil lubrication bearing box exhaust device provided by the embodiment of the application comprises an exhaust cylinder 1, a cover 2 and a steel ball 3. The exhaust cylinder 1 is arranged on the oil lubrication bearing box. The exhaust cylinder 1 has an exhaust groove 4 inside. The cover 2 is detachably arranged on the exhaust cylinder 1. The cover 2 is provided with a plurality of exhaust holes 5. The steel ball 3 is arranged between the exhaust cylinder 1 and the cover 2. The lower end of the steel ball 3 enters the inside of the exhaust groove 4.

[0030] In use, the hot gas generated during the rotation of the bearing carries the oil mist into the inside of the exhaust groove 4. Then the gas passes through the steel ball 3 and is discharged through the exhaust holes 5. The oil mist is deflected after impacting the steel ball 3 and is captured by the steel ball 3. The oil mist is gathered into oil droplets and then flows back to the inside of the oil lubrication bearing box along the exhaust groove 4 under the action of gravity. Thus, the function of environmentally friendly and oil-saving exhaust can be realized. Since the exhaust holes 5 are arranged on the cover 2 and have a larger diameter than the original design, the cleaning is more convenient and the cleaning efficiency is improved.

[0031] In the embodiment, the upper end of the exhaust groove 4 is flared. Since the steel ball 3 covers the upper end of the exhaust groove 4 when the steel ball 3 is installed, the flared upper end of the exhaust groove 4 can increase the exhaust area and ensure the exhaust effect of the device. The lower end of the exhaust groove 4 is in a funnel structure. The funnel-shaped lower end of the exhaust groove 4 can facilitate the backflow of the oil droplets and effectively support the steel ball 3.

[0032] In the embodiment, the cover 2 has an internal thread 8. The outer wall of the upper end of the exhaust cylinder 1 is provided with an external thread 6. The cover 2 is threadedly connected with the exhaust cylinder 1. The threaded connection facilitates the disassembly and assembly of the cover 2, thereby facilitating the replacement or cleaning of the steel ball 3.

[0033] In the embodiment, the cover 2 is provided with anti-slip embossing 9. The anti-slip embossing 9 is used to increase the friction, thereby facilitating the screwing of the cover 2.

[0034] In the embodiment, the outer wall of the lower end of the exhaust cylinder 1 is provided with an external thread 6. The exhaust cylinder 1 is threadedly arranged on the oil lubrication bearing box.

[0035] In the embodiment, the outer wall of the lower end of the exhaust cylinder 1 is provided with an O-shaped sealing ring 7. The O-shaped sealing ring 7 is used to seal between the exhaust cylinder 1 and the oil lubrication bearing box, thereby blocking the volatilization of the oil gas inside the oil lubrication bearing box.

[0036] In the embodiment, the O-shaped sealing ring 7 is made of oil-resistant and high-temperature-resistant material, which can prolong the service life of the O-shaped sealing ring 7.

[0037] Embodiment two

[0038] As Figure 2As shown, different from the embodiment one, in the embodiment, the upper end of the exhaust groove 4 is flared, the middle part of the exhaust groove 4 is a funnel structure, the lower end of the exhaust groove 4 is a cylindrical structure, the cross-sectional area of the middle part lower end of the exhaust groove 4 is smaller than the cross-sectional area of the lower end of the exhaust groove 4, the cross-sectional area of the middle part upper end of the exhaust groove 4 is smaller than the cross-sectional area of the upper end of the exhaust groove 4, and the above structure can increase the flow rate of the gas, which is more conducive to the discharge of the gas.

[0039] The above only is the preferred embodiment of the present application, and is not used to limit the present application, and the present application can have various changes and changes for the person skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
