[0022] The figure marks in the drawings of the specification include: bearing seat 1, working roll 2, shaft neck 201, end face 202, mounting groove 203, bearing 3, transparent cover 4, connecting ring 401, first water retaining part 402, drainage hole 403, distance ring 5, second water retaining part 501, first annular groove 6, annular flow channel 7, second annular groove 8.
[0023] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0024] Example
[0025] like Figures 1 to 7 As shown, this embodiment provides a water ingress prevention structure for a bearing seat, comprising: a distance ring 5 and a transparent cover 4, wherein the distance ring 5 and the transparent cover 4 are arranged between the end of the bearing seat 1 and the end of the working roll 2. A mounting groove 203 is provided on the working roll 2.
[0026] A boss for abutting against the end of the bearing 3 is protruding from the first end of the transparent cover 4, and a connecting ring 401 is protruding from the middle of the end surface of the second end of the transparent cover 4. The connecting ring 401 is arranged along the axis of the bearing seat 1, and a first water retaining portion 402 is arranged at one end of the connecting ring 401 away from the bearing seat 1. The first water retaining portion 402 is arranged perpendicular to the connecting ring 401. A drainage hole 403 is opened through the connecting ring 401 and the first water retaining portion 402.
[0027] The outer diameter of the second end of the distance ring 5 increases in a step-like manner, and a second water retaining portion 501 is protruding outwardly on the circumference of the second end of the distance ring 5 . The second water retaining portion 501 is arranged perpendicular to the second end of the distance ring 5 .
[0028] The first water retaining portion 402 and the second water retaining portion 501 are both ring-shaped.
[0029] When the distance ring 5 and the transparent cover 4 are assembled to the bearing seat 1 and the working roll 2, the distance ring 5 is used to be sleeved outside the journal 201 of the working roll 2, the transparent cover 4 is used to be sleeved outside the distance ring 5, and the transparent cover 4 is screwed to the bearing seat 1. The first end of the transparent cover 4 and the first end of the distance ring 5 are against the end of the bearing 3, the second end of the distance ring 5 extends into the installation groove 203, and the first water retaining part 402 and the second water retaining part 501 are located in the installation groove 203, and the first water retaining part 402 and the second water retaining part 501 are parallel and arranged around the outside of the journal 201 of the working roll 2.
[0030] A first annular groove 6 is formed between the second end of the transparent cover 4 and the end face 202 of the working roller 2, a second annular groove 8 is formed between the connecting ring 401 and the distance ring 5, the first water retaining portion 402 is matched with the clearance between the upper and lower side walls of the mounting groove 203, the second water retaining portion 501 is matched with the clearance between the inner wall of the connecting ring 401, and an annular flow channel 7 is formed between the first water retaining portion 402 and the right inner wall of the mounting groove 203, the first annular groove 6 and the annular flow channel 7 are connected through the gap between the first water retaining portion 402 and the upper and lower side walls of the mounting groove 203, and the second annular groove 8 and the annular flow channel 7 are connected through the gap between the second water retaining portion 501 and the connecting ring 401.
[0031] A skeleton sealing ring is arranged between the first end of the transparent cover 4 and the first end of the distance ring 5 .
[0032] The drainage hole 403 is provided at the bottom of the transparent cover 4 , so that the first annular groove 6 , the second annular groove 8 and the annular flow channel 7 are connected.
[0033] When in use, when the high-pressure water on the outside of the working roll 2 impacts downward onto the connecting ring 401, the setting of the first water retaining part 402 blocks most of the water. When the water flow is large, the water flow will enter the annular flow channel 7 from the gap between the first water retaining part 402 and the upper and lower side walls of the mounting groove 203, and then flow out from the bottom of the first annular groove 6. The setting of the drainage hole 403 speeds up the water outflow speed and avoids water accumulation. The inner diameter of the first water retaining part 402 is smaller than the inner diameter of the connecting ring 401, so that the setting of the first water retaining part 402 and the second water retaining part 501 prevents the water flow from entering the second annular groove 8 from the annular flow channel 7. If water enters the second annular groove 8, it can also be discharged through the drainage hole 403. The setting of the skeleton sealing ring prevents the water in the second annular groove 8 from entering the bearing 3.
[0034] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
