DETAILED DESCRIPTION
[0022] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.
[0023] A split bearing seat seal body, such as Figure 1-Figure 5 As shown, it includes a split shell 1 and a bearing hole arranged on the shell 1, and sealing components are symmetrically arranged on both sides of the shell 1. The sealing component includes a sealing cover 2 and a sealing member 3. The sealing member 3 is located between the sealing cover 2 and the shell 1, and the inner diameter of the sealing member 3 is equal to the aperture of the bearing hole. The sealing cover 2 is composed of an upper cover body 21 and a lower cover body 22 symmetrically arranged with each other. The upper cover body 21 and the lower cover body 22 are both detachably connected to one side of the shell 1 by bolts. The sealing member 3 includes an upper sealing body 31 and a lower sealing body 32 symmetrically arranged with respect to the center, and the upper sealing body 31 is detachably connected to the sealing cover 2, and the lower sealing body 32 is detachably connected to the side wall of the shell 1; by dividing the sealing member 3 into an upper sealing body 31 and a lower sealing body 32, and the sealing cover 2 is also divided into an upper cover body 21 and a lower cover body 22, the separation of the sealing member 3 and the sealing cover 2 can be completed, and the replacement of the sealing member 3 can be performed without removing the shaft body or the shell 1, and the operation is more convenient.
[0024] The side wall of the housing 1 is provided with a first receiving groove 11 for engaging the lower sealing body 32, and the sealing cover 2 is provided with a second receiving groove 23 for engaging the upper sealing body 31, which can limit the seal 3 to prevent it from being distorted, thereby ensuring the sealing effect of the seal 3. The cross-sections of the upper sealing body 31 and the lower sealing body 32 are both C-shaped, and the cross-sections of the upper cover 21 and the lower cover 22 are both semicircular. The cross-sections of the upper sealing body 31 and the lower sealing body 32 are both C-shaped, so that when the two sealing bodies are centrally symmetrical and fitted, there will be overlapping parts, thereby further ensuring the sealing effect; the cross-sections of the first receiving groove 11 and the second receiving groove 23 are both annular, ensuring the accommodation effect;
[0025] The depth of the second receiving groove 23 is greater than the thickness of the upper sealing body 31, the depth of the first receiving groove 11 is less than the thickness of the lower sealing body 32, and the thickness of the upper sealing body 31 is consistent with that of the lower sealing body 32, so that the upper sealing body 31 can be completely integrated into the second receiving groove 23, and one side of the lower sealing body 32 can extend out of the first receiving groove 11 and extend into the second receiving groove 23; a plurality of extrusions 26 are distributed in an annular array on the sealing cover 2, and the plurality of extrusions 26 are all connected in a radial sliding manner along the sealing cover 2, a plurality of sliding grooves 25 for accommodating the extrusions 26 are provided on the inner wall of the second receiving groove 23, and an annular groove 24 is provided on the sealing cover 2, and the sliding groove 25 is away from One end of the second accommodating groove 23 is connected to the annular groove 24, one end of the extrusion piece 26 extends toward the annular groove 24 and extends into the annular groove 24, and is provided with an inclined guide surface, and an annular piece 12 is integrally formed on the shell 1 and inserted into the annular groove 24; due to the setting of the extrusion piece 26, when the annular piece 12 is inserted into the annular groove 24, the extrusion piece 26 has a good guiding effect due to the existence of a guide surface, and the annular piece 12 can push the extrusion piece 26 toward the second accommodating groove 23, thereby squeezing the upper sealing body 31 and the lower sealing body 32 of the second accommodating groove 23, thereby ensuring the sealing effect of the upper sealing body 31 and the lower sealing body 32.
[0026] The upper cover 21 and the lower cover 22 are provided with mutually plugged positioning members 211 and positioning holes 221 respectively on one side thereof. When the upper cover 21 and the lower cover 22 are combined to form the entire sealing cover 2, the positioning member 211 is inserted into the positioning hole 221, thereby achieving a good positioning effect and ensuring the stability of the sealing cover 2.
[0027] Working principle: After the shell 1 is installed, the lower sealing body 32 is inserted into the first receiving groove 11 on the shell 1, and the upper sealing body 31 is inserted into the second receiving groove 23 of the upper cover 21. The upper cover 21 and the lower cover 22 are combined to form the sealing cover 2, and the positioning member 211 is inserted into the positioning hole 221, so that the upper sealing body 31 is completely received in the second receiving groove 23, and the sealing cover 2 is close to the side of the shell 1, and the annular member 12 on the shell 1 is inserted into the annular groove 24, and the annular member 12 touches The guide surface of the extrusion piece 26 enables the extrusion piece 26 to move toward the second accommodating groove 23, thereby causing the extrusion piece 26 to be squeezed toward the outer peripheral wall of the upper sealing body 31. Since a portion of the lower sealing body 32 also extends into the second accommodating groove 23 at this time, the extrusion piece 26 squeezes the outer peripheral wall of the lower sealing body 32 at the same time, thereby ensuring that the upper sealing body 31 and the lower sealing body 32 are fixed more stably while also ensuring the sealing effect; at this time, the sealing cover 2 is fixedly connected to the shell 1 by bolts to complete the installation of the overall sealing assembly.
[0028] When disassembly is required, since the sealing cover 2 is divided into two parts, the upper and lower parts can be separated from the shell 1 by simply removing the bolts from the shell 1, and the upper cover 21 and the lower cover 22 can be separated. At this time, the upper sealing body 31 and the lower sealing body 32 can be disassembled, which is convenient for replacement, simple in structure, and easy to operate.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
