DETAILED DESCRIPTION

[0022] The technical scheme of the present application will be described clearly and completely below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Referring to Figures 1 to 5 , the present application provides a technical scheme: a bearing cover convenient to disassemble, comprising an annular seat 1, the edge of the annular seat 1 is provided with a plurality of mounting holes 2, the mounting holes 2 are fastened on the bearing seat by bolts, so that the annular seat 1 is fixed between the bearing seat.

[0024] As Figure 1 and Figure 2 shown, a plurality of L-shaped clamping seats 4 are arranged on the inner circumferential side of the annular seat 1, the clamping seats 4 are arranged at equal intervals, and the clamping groove 3 is formed between the clamping seat 4 and the annular seat 1. The center of the annular seat 1 is provided with a sealing cover 8, the edge of the sealing cover 8 is provided with a clamping block 14 corresponding to the clamping seat 4, when the sealing cover 8 is coaxially arranged in the middle of the annular seat 1, the state between the sealing cover 8 and the clamping seat 4 at this time is shown in Figure 2 , then the sealing cover 8 is rotated so that the clamping block 14 is rotated into the clamping groove 3, that is, the clamping block 14 is rotated into the clamping seat 4, and the clamping block 14 and the clamping groove 3 are in wedge surface contact, specifically, the side of the clamping block 14 and the clamping groove 3 away from the annular seat 1 is designed as an inclined surface, when the clamping block 14 is placed in the clamping groove 3, the two inclined surfaces are in contact, so that when the sealing cover 8 is rotated with force, the pressure of the clamping groove 3 on the clamping block 14 will become larger and larger, thereby tightly pressing the sealing cover 8 on the surface of the annular seat 1;

[0025] In order to ensure that the annular seat 1 and the sealing cover 8 are completely sealed, as Figure 3 shown, an annular groove 15 is arranged on the inner edge of the annular seat 1 close to the sealing cover 8, and a sealing ring in elastic contact with the sealing cover 8 is arranged in the annular groove 15, so that the gap between the annular seat 1 and the sealing cover 8 is completely sealed.

[0026] In the present application, a locking device for fastening the sealing cover 8 is arranged on at least one clamping seat 4, in practical application, one locking device can lock and fix the sealing cover 8;

[0027] The specific composition of the locking device will be specifically introduced below, asFigure 2 As shown, the locking device includes a connecting seat 5 arranged on the clamping block 14 away from the annular seat 1, and further includes a strip-shaped seat 6, one end of which is arranged on the sealing cover 8, and the other end of which is located outside the sealing cover 8; as Figure 1 As shown, when the clamping block 14 is rotated into the clamping groove 3, the strip-shaped seat 6 is located on one side of the connecting seat 5, and a certain spacing is provided between the strip-shaped seat 6 and the connecting seat 5, and the strip-shaped seat 6 and the connecting seat 5 are fastened by bolts, when the end of the bolt is provided with a nut, the nut is arranged on the connecting seat 5, and when the nut is gradually tightened, the screw pulls the strip-shaped seat 6 to move towards the connecting seat 5, so that the spacing between the strip-shaped seat 6 and the connecting seat 5 is used to pull the strip-shaped seat 6, so that the strip-shaped seat 6 drives the clamping block 14 to continue to rotate into the clamping groove 3, so that the clamping groove 3 tightly presses the clamping block 14 towards the annular seat 1, so that the pressure between the annular seat 1 and the sealing cover 8 is large enough to ensure complete sealing;

[0028] It should be noted that since the strip-shaped seat 6 moves in an arc shape when approaching the connecting seat 5, the bolts connecting the two need to be adjusted in position according to the movement of the strip-shaped seat 6. According to the above situation, an adjusting port 12 is arranged at the end of the strip-shaped seat 6, and the end of the connecting seat 5 away from the annular seat 1 is in a U-shaped structure, and the two ends of the bolt are arranged in the U-shaped structure and the adjusting port 12 respectively. As Figure 5 As shown, one end of the bolt is connected perpendicularly to the middle of the cylindrical head 16, and a placing groove 13 is arranged at the top of the strip-shaped seat 6 away from the connecting seat 5, and the two ends of the cylindrical head 16 are arranged in the placing groove 13 and can rotate freely;

[0029] It should be noted that the axis of the placing groove 13 is parallel to the axis of the sealing cover 8, and the opening in the U-shaped structure and the adjusting port 12 are perpendicular to each other, and the size of the opening in the U-shaped structure and the adjusting port 12 is larger than the size of the bolt, so that when the nut is tightened, the bolt can automatically adjust the position in the U-shaped structure and the adjusting port 12 and the placing groove 13.

[0030] Further, if the installed shaft end needs to extend to the outside of the sealing cover, then the middle of the sealing cover 8 needs to have a hole to accommodate the shaft. As Figure 4 As shown, a shaft sleeve 11 is coaxially arranged in the middle of the sealing cover 8, a sealing assembly is arranged in the shaft sleeve 11, the sealing assembly includes a sealing ring groove 10 arranged at the port of the shaft sleeve 11, a sealing ring is arranged in the sealing ring groove 10, a limiting ring 9 is detachably arranged at the end of the shaft sleeve 11, the limiting ring 9 is used to block the sealing ring from sliding out of the sealing ring groove 10, and the limiting ring 9 and the end of the shaft sleeve 11 are fastened by a plurality of bolts.

[0031] Further, at least one oil injection hole is arranged at the edge of the sealing cover 8, a sealing bolt 7 is screwed in the oil injection hole, when the oil injection hole is opened, the nozzle of an oil injection gun is placed in the oil injection hole, the inside of the sealing cover 8 can be injected with oil, and the bearing is lubricated.

[0032] In conclusion, the bearing cover in use, first the annular seat 1 is installed with the bearing seat, and then the sealing cover 8 can be not moved for a long time, when the bearing needs to be maintained or disassembled, only the bolt in the connecting seat 5 is loosened and removed, the sealing cover 8 is rotated, the clamping block 14 is rotated out of the placing groove 13, and then the sealing cover 8 is removed;

[0033] When the bearing needs to be installed, only the sealing cover 8 is placed in the middle of the annular seat 1, the sealing cover is rotated to drive the clamping block 14 to rotate into the placing groove 13, the bolt is installed in the connecting seat 5 and the strip-shaped seat 6, the pressure between the clamping block 14 and the placing groove 13 is larger and larger with the bolt being screwed tighter and tighter, so that the sealing cover 8 is tightly pressed on the annular seat 1 to ensure the sealing.

[0034] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
