[0035] Embodiment:
[0036] As Figures 1 to 3 shown, the present invention provides a split bearing seat, including:
[0037] The first body 1, the first body 1 includes a base 2 and a support base 3, the support base 3 is disposed on the base 1, the support base 3 is provided with a rotating shaft hole 301 whose axis extends along the first direction, one end of the support base 3 has a first flange 302, and the central hole of the first flange 301 communicates with the rotating shaft hole 301;
[0038] The second seat body 4, the second seat body 4 includes a protective cylinder 5, a second flange 6 and a third flange 7; the protective cylinder 5 has a receiving cavity 501 for receiving the coupling 14, the axis of the receiving cavity 4 extends in the first direction and both ends of the receiving cavity 501 are open, the second flange 6 and the third flange 7 are distributed in the first direction and are respectively located at both ends of the protective cylinder 5, and the central holes of the second flange 6 and the third flange 7 are both communicated with the receiving cavity 501. In this embodiment, the first direction is the horizontal direction. During assembly, the first flange 302 is bolted to the second flange 6 so that the rotating shaft hole 301 is communicated with the receiving cavity 501, the third flange 7 is bolted to the mounting plate of the motor 13, and the shaft end of the roller passes through the rotating shaft hole 301 and then extends into the receiving cavity 501. The coupling 14 is located in the receiving cavity 501, and the shaft end of the roller and the output shaft of the motor 13 are connected through the coupling 14. Through this setting, during the maintenance process, only the bolts between the first flange 302 and the second flange 6 and the bolts between the third flange 7 and the mounting plate of the motor 13 need to be removed to replace the coupling, without the need to remove and displace the roller end, saving the cumbersome problems of installing and disassembling the roller end, reducing the installation and disassembly time, and improving the equipment maintenance operation rate.
[0039] Existing bearing seats are all designed with an integral sealed structure, and maintenance personnel cannot intuitively check the damage degree of the coupling inside the bearing seat on the shaft side, which may lead to the failure to detect potential fault hazards in time. When the coupling is damaged, the roller does not rotate. Since the damage degree cannot be intuitively judged, it may cause scratches on the steel belt, thereby affecting the product quality. Therefore, an observation window 8 is opened on the protective cylinder 5 in this embodiment to facilitate observing the wear condition of the coupling 14 inside the protective cylinder 5, so that maintenance personnel can intuitively check the damage degree of the coupling and detect fault hazards in time.
[0040] During implementation, the observation window 8 can be opened at the top or side of the protective cylinder 5. When the split bearing seat is installed on the ground, the observation window 8 is opened at the top of the protective cylinder 5; when the split bearing seat is installed at a higher position, the observation window 8 is opened at the side of the protective cylinder 5. According to the actual use situation, determine the opening position of the observation window to facilitate the maintenance personnel to check the coupling mode inside the protective cylinder. The size of the observation window 8 is such that maintenance personnel can observe the internal coupling. The size of the observation window 8 should not be too large (its width should not exceed the diameter of the protective cylinder), so as not to reduce the ability of the protective cylinder to withstand the motor torque and reduce its service life.
[0041] The first housing body 1 in this embodiment further includes a support block 9. The support block 9 is arranged on the base 2 and is close to the first flange 302. When the first flange 302 is bolted to the second flange 6, the support block 9 is located at the bottom end of the second housing body 4 and is fitted with the second housing body 4 to limit the rotation of the second housing body 4 around the first direction. At the same time, the torque force between the first housing body 1 and the second housing body 4 is increased. When the motor works and generates vibration, the overall stability of the split bearing housing is improved.
[0042] Specifically, a positioning hole 10 with an opening facing downwards is formed at the bottom end of the second flange 6. The first end of the support block 9 is connected to the first flange 302, and the second end of the support block 9 extends below the protective cylinder 5. When the first flange 302 is bolted to the second flange 6, the positioning hole 10 is fitted with the support block 9, and the support block 9 is in close contact with the bottom of the protective cylinder 5 to support the protective cylinder 5 and further improve the connection stability between the first housing body 1 and the second housing body 4.
[0043] In another embodiment, positioning holes 10 with openings facing downwards are formed at the bottom ends of both the second flange 6 and the third flange 7. The first end of the support block 9 is connected to the first flange 302, and the second end of the support block 9 extends below the third flange 7. When the first flange 302 is bolted to the second flange 6, the positioning hole 10 is fitted with the support block 9, and the support block 9 is in close contact with the bottom of the protective cylinder 5. Through this setting, both the second flange 6 and the third flange 7 are fitted with the support block 9 through the positioning holes 10, further increasing the torque force between the first housing body 1 and the second housing body 4 and improving the connection stability between the first housing body 1 and the second housing body 4.
[0044] In another embodiment, a positioning hole 10 with an opening facing downwards is formed at the bottom end of the third flange 7. The first end of the support block 9 is close to the first flange 302 and there is a clearance interval between the support block 9 and the first flange 302. The bottom of the support block 9 extends below the third flange 7. When the first flange 302 is bolted to the second flange 6, the bottom end of the second flange 6 is located within the clearance interval, the positioning hole 10 is fitted with the support block 9, and the support block 9 is in close contact with the bottom of the protective cylinder 5. Through this setting, the support block 9 makes corresponding structural changes according to the positioning hole 10 being arranged on the second flange 6 and / or the third flange 7, ensuring that the support block 9 can support the protective cylinder 5 and increase the torque force between the first housing body 1 and the second housing body 4.
[0045] In this embodiment, a sewage discharge hole 10 is formed at the bottom end of the protective cylinder 5. By providing the sewage discharge hole 10, lubricating oil, dust, etc. inside the protective cylinder 5 can be discharged. A corresponding support block 9 is provided with a groove 12, and the groove 12 is directly below the sewage discharge hole 10. By providing the groove 12, it is convenient for the sewage in the sewage discharge hole 10 to flow out.
[0046] In this embodiment, the base 2 is provided with a plurality of bolt holes for fixing the base 2 to the ground or other installation surfaces by bolts.
[0047] This embodiment also discloses a transmission mechanism, which includes the above-mentioned split bearing seat, and also includes a motor 13 and a coupling 14. The first flange 302 is bolted to the second flange 6, and the third flange 7 is bolted to the mounting plate of the motor 13. The shaft end of the roller extends into the accommodation cavity 501 through the shaft hole, and the coupling 14 is located in the accommodation cavity 501 to connect the shaft end of the roller and the output shaft of the motor 13. By applying the split bearing seat in this transmission mechanism, the maintenance time can be shortened, thereby reducing the idle time of the equipment and improving the use efficiency and economic benefits of the equipment.
[0048] Preferably, the coupling 14 is a plum blossom-shaped elastic coupling. By providing the plum blossom-shaped elastic coupling, during the maintenance process, only the bolts between the third flange plate and the motor mounting plate need to be removed, and there is no need to remove the plum blossom-shaped elastic coupling body itself, so that the elastic body can be replaced, shortening the assembly time and reducing the labor input, effectively improving the production efficiency and reducing the production cost.
[0049] When replacing the coupling of the existing bearing seat, it is often necessary to remove other equipment connected thereto, such as motors, rollers, etc., which increases the difficulty and complexity of maintenance. Installing and disassembling the roller coupling takes a relatively long time, and the operation process is relatively cumbersome. By using the transmission mechanism equipped with the plum blossom-shaped elastic coupling, the damage degree of the coupling can be visually inspected through the observation window. During the maintenance process, only the bolts between the third flange plate and the motor mounting plate need to be removed, and the motor is shifted, then the plum blossom-shaped elastic coupling can be taken out to replace the elastic body.
[0050] Applying the transmission mechanism in this embodiment has at least the following advantages:
[0051] 1. Improve production efficiency: The shortening of the equipment assembly time can improve the production efficiency, thereby increasing the production capacity and reducing the production cost.
[0052] 2. Improve equipment utilization rate: The shortening of the equipment assembly time can improve the utilization rate of the equipment, thereby reducing the idle time of the equipment and improving the use efficiency and economic benefits of the equipment.
[0053] 3. Reduce labor costs: The shortening of the equipment assembly time can reduce the labor input, lower the labor costs, and at the same time reduce the waste of human resources.
[0054] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
