DETAILED DESCRIPTION

[0013] A bearing seat oil ingress prevention device, such as Figures 1 to 2 As shown, the bearing seat anti-oil ingress device is described in detail by combining it with an application device, the application device includes a column 6, two parallel guide rails 7, and a servo motor 9 connected to the upper end of the column through a motor seat 8, wherein a transmission shaft 4 is provided between the two guide rails 7, one end of the transmission shaft 4 is connected to the servo motor 9, and the other end of the transmission shaft 4 is connected to the bearing seat 1. The bearing seat anti-oil ingress device includes a blowing component 2 arranged on the outside of the bearing seat 1, the blowing component 2 includes a gas delivery component 21, an air flow adjustment component 23 connected to the gas delivery component 21, and an air outlet 22, the air outlet 22 is connected to one end of the gas delivery component 21 and docked with the end surface of the bearing seat 1 connected to the transmission shaft 4 to blow away the oil between the seal 11 of the bearing seat 1 and the transmission shaft 4. By setting a blowing component 2 independent of the bearing seat 1 to blow away the oil between the seal 11 of the bearing seat 1 and the transmission shaft 4, the oil is effectively prevented from flowing into the inside of the bearing seat 1, and the service life of the bearing seat 1 is extended.

[0014] In another embodiment, the bearing seat anti-oil inflow device also includes an oil guide component 3 arranged on the end face of the bearing seat 1, and the oil guide component 3 can cooperate with the blowing component 2 to guide out the oil on the end face. The setting of the oil guide component 3 can better guide out the oil on the end face of the bearing seat 1, not only can it cooperate with the blowing component 2 to guide out the oil, but also can guide it spontaneously according to its own structure. Preferably, the oil guide component 3 includes an oil guide groove 31, one end of the oil guide groove 31 is connected to the joint area of ​​the seal 11 and the transmission shaft 4, and the other end of the oil guide groove 31 is connected to the outer peripheral surface of the bearing seat 1. In use, on the basis of the operation of the blowing component 2, the oil adsorbed around the seal 11 will be guided out through the oil guide groove 31 under the action of the airflow, ensuring that there is no oil between the seal 11 and the transmission shaft 4. Even if the blowing component 2 is not in operation, part of the oil on the end face of the bearing seat 1 will be guided out through the oil guide groove 31, reducing the accumulation of oil in the joint area of ​​the seal 11 and the transmission shaft 4, preventing oil from entering the inside of the bearing seat 1, and effectively extending the service life of the bearing seat 1.

[0015] In another embodiment, the air outlet 22 of the air blowing component 2 is arranged opposite to one end of the oil guide groove 31 near the joint area so as to blow the oil on the end surface into the oil guide groove 31. By arranging the air outlet 22 opposite to one end of the oil inlet of the oil guide groove 31, the oil can be better blown into the oil guide groove 31 under the action of the airflow, and the oil in the joint area between the transmission shaft 4 and the seal 11 can be better removed, further ensuring that there is no oil between the seal 11 and the transmission shaft 4, and effectively extending the service life of the bearing seat 1.

[0016] In another embodiment, the gas delivery assembly 21 of the blowing component 2 includes a blowing pipe, one end of which is connected to the air outlet 22, and the air flow adjustment assembly 23 includes a regulating valve, which is connected to the blowing pipe and can adjust the strength of the air flow at the air outlet 22 to blow away the oil stains. The air flow size of the air outlet 22 can be flexibly controlled by the regulating valve, and can be adjusted differently according to actual needs, so that the oil stains between the seal 11 and the transmission shaft 4 can be better removed, and the service life of the bearing seat 1 can be further extended.

[0017] The bearing seat anti-oil inflow device ensures an oil-free working condition between the seal 11 and the transmission shaft 4 by setting an air blowing component 2 independent of the outer side of the bearing seat 1 and an oil guide component 3 set on the end face of the bearing seat 1, which not only effectively reduces the wear between the transmission shaft 4 and the seal 11 and prolongs the service life of both, but also effectively prevents oil from flowing into the interior of the bearing seat 1, prolonging the service life of the bearing seat 1 and reducing the customer's use cost. In addition, the bearing seat anti-oil inflow device has a simple structure, is easy to produce, and can be flexibly installed on different equipment, has strong adaptability, is easy to use and has low manufacturing cost.

[0018] The above implementation modes are exemplary, and their purpose is to illustrate the technical concept and features of the utility model so that people familiar with the technology in this field can understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
