[0023] The utility model provides a split bearing seat, solve existing bearing seat easy to break, inconvenient to disassemble or higher cost problem, with more simple and effective mode realizes bearing seat split structure, and guarantees size precision.

[0024] Please refer to Figures 1 to 3 The utility model discloses a split bearing seat, including from bottom to top setting in proper order bottom plate 1, lower seat body 2 and upper seat body 3. Lower seat body 2 and upper seat body 3 are two half circular arc structures ( the half circular pipe structure of cutting open circular pipe along the axial direction vertically) with the seamless steel pipe of same model. Preferably, the wall thickness of the seamless steel pipe that lower seat body 2 and upper seat body 3 adopt is not less than 10mm, to guarantee its structural strength as bearing seat.

[0025] Lower connecting lug plate 4 is fixedly connected (such as welding) in the both ends (left and right ends) of lower seat body 2, and upper connecting lug plate 5 is fixedly connected (such as welding) in the both ends (left and right ends) of lower seat body 2, and lower connecting lug plate 4 is detachably connected with upper connecting lug plate 5 through bolt 6;In the state of connection, lower seat body 2 and upper seat body 3 splice into circle, and lower seat body 2 and upper seat body 3 hold positioning bearing between each other. More specifically, relative to the complete circle in strict sense, lower seat body 2 and upper seat body 3 have the clearance of for example 0.50mm between each other, to make the circle can reduce size to a certain extent, guarantee enough positioning effect to bearing.

[0026] The lower seat body 2 is connected to the middle part of the bottom plate 1, both ends (left and right ends) of the bottom plate 1 are provided with bottom plate bolt mounting slot holes 7, one end of the bottom plate bolt mounting slot hole 7 away from the lower seat body 2 is an opening, and the openings of the bottom plate bolt mounting slot holes 7 at both ends face away from each other (the opening of the bottom plate bolt mounting slot hole 7 on the left side faces left, and the opening of the bottom plate bolt mounting slot hole 7 on the right side faces right). The bottom plate bolt mounting slot hole 7 is used to realize the connection of the bottom plate 1 and the remaining part of the equipment, or the rack, the ground and other fixed structures by bolt. It can be thought that the bearing seat may vibrate during the operation of the large equipment, and if the slot hole structure with the through opening and the openings facing the same side is adopted, the bearing seat may move; in the scheme, the openings of the bottom plate bolt mounting slot holes 7 face away from each other, the bolts therein form a mutual restraint relationship with the closed end inside the bottom plate bolt mounting slot hole 7, so that the bearing seat cannot move in the left and right directions, and at the same time, it is limited by the front and rear sidewalls of the bottom plate bolt mounting slot hole 7 in the front and rear directions, so that it can be fixed stably while being convenient to disassemble.

[0027] More specifically, a mounting groove is provided on the upper surface of the bottom plate 1, and the lower part of the lower seat body 2 is matched and embedded in the mounting groove. The lower seat body 2 and the bottom plate 1 are fixed by welding, or the lower part of the lower seat body 2 is provided with a vertical or horizontal hole, and the bottom plate 1 is provided with a corresponding hole, so as to be detachably connected by bolts.

[0028] Preferably, an avoiding groove 8 is further provided on the upper surface of the bottom plate 1, the avoiding groove 8 is located on the front and rear sides of the axis direction of the circle formed by the splicing of the lower seat body 2 and the upper seat body 3, and the upper surface of the avoiding groove 8 is not higher than the upper surface of the lower seat body 2. The avoiding groove 8 is used to ensure the space for setting the shaft, reduce the overall height of the bearing seat, and help stable operation. In addition, for the detachable connection scheme of the lower seat body 2 and the bottom plate 1, it is also convenient for disassembly and installation of the lower seat body 2 and the bottom plate 1. More preferably, the upper surface of the avoiding groove 8 is lower than the upper surface of the lower seat body 2, and the contour line of the upper surface of the avoiding groove 8 is a concentric circular arc with the contour line of the upper surface of the lower seat body 2. The avoiding groove 8 with a circular arc structure has small size and smooth curve, which can ensure that the structural strength of the bottom plate 1 is not significantly weakened due to the opening of the avoiding groove 8.

[0029] Please refer to Figure 5Preferably, bolt mounting holes 9 for connecting bolts 6 are provided at both ends of the lower seat body 2 and the upper seat body 3, and two bolt mounting holes 9 distributed along the axis direction of the circular joint of the lower seat body 2 and the upper seat body 3 are provided at each end; in other words, two bolts 6 are provided at each of the left and right sides, and a total of four bolts are used for connection. This parallel-axle bolt connection arrangement makes the lower seat body 2 and the upper seat body 3 have stronger torsional resistance after connection, further ensuring the stability of the connection. More specifically, among the bolt mounting holes 9 corresponding to the upper and lower ends of the upper seat body 3 and the lower seat body 2, one is a through hole (a through hole without internal threads), and the other is a threaded hole, for example Figure 2 In the embodiment shown in the figure, the upper end is a through hole, and the lower end is a threaded hole, so that the bolt 6 can be tightened downward during installation. In other possible embodiments, the bolt mounting holes 9 of the upper seat body 3 and the lower seat body 2 are both through holes, and the end of the bolt 6 is provided with a matching nut.

[0030] Please refer to Figure 4 Preferably, the upper surface of the lower seat body 2 and the lower surface of the upper seat body 3 are formed with a recessed spherical surface, so as to match the internal bearing structure, and the bearing is positioned more stably. The spherical surface is formed by cutting or stamping, for example.

[0031] Please refer to Figure 1 In a specific embodiment, the planes of the upper connecting ear plate 5, the lower connecting ear plate 4, and the bottom plate 1 are parallel, and are all transverse. The upper connecting ear plate 5 and the lower connecting ear plate 4 protrude from the upper seat body 3 and the lower seat body 2. Further, the lower connecting ear plate 4 is located above the bottom plate bolt mounting slot hole 7, and has a spacing distance with the bottom plate 1. In this way, the installation and removal of the bolts 6 of the upper seat body 3 and the lower seat body 2, and the installation and removal of the bolts on the bottom plate bolt mounting slot hole, provide sufficient operation space.

[0032] In summary, the detachable bearing seat of the present application is made of seamless steel pipe, thereby ensuring the matching between the detachable seat body parts and the inner side dimension precision, and having better rigidity and toughness. The seamless steel pipe technology is mature, easy to process or purchase, and has low material cost and subsequent processing cost. The two ends of the upper and lower semicircular seat bodies are connected by bolts, which is simple and reliable. The two ends of the bottom plate are provided with slot holes, which are easier to install and remove than conventional circular holes. Since the openings are opposite to each other, the structures of the two ends can limit each other, effectively preventing the bearing seat from shifting.
