[0006] In order to optimize the above technical solution, further measures are taken as follows: the axis of the installation groove and the axis of the through hole coincide with each other, the installation groove is located on the opposite side of the installation plate, and the axis coincidence ensures that the connecting shaft is located in the through hole when the bearing ring is set in the installation groove, ensuring smooth rotation of the bearing ring.
[0007] As a further improvement of the above technical solution: the contact surface between the cover shell and the mounting plate is concave to form a groove matching the convex strip, the convex strip is located on the left and right sides of the mounting plate, and the groove and the convex strip match to improve the limiting effect of the cover shell on the mounting plate and suppress the runout of the bearing ring.
[0008] As a further improvement of the technical solution: the groove and the convex strip constitute a moving pair in the height direction of the mounting plate, and such a moving pair design ensures that the groove and the convex strip can be smoothly disassembled and assembled.
[0009] As an improvement to the aforementioned technical solution: the first connecting plate and the second connecting plate have the same area and the screw holes on the first connecting plate correspond in position to the screw holes on the second connecting plate. When the bolts are fixed to the first connecting plate, the second connecting plate and the mounting surface, the bearing seat and the mounting surface can be fixed, and the first connecting plate and the second connecting plate can also be fixed.
[0010] Furthermore: the screw holes on the first connecting plate are respectively located on both sides of the first connecting plate and are symmetrically distributed. The symmetrical distribution helps to improve the fixing effect of the bolts on the first connecting plate.

[0019] Example
[0020] See also Figure 1-3 The utility model provides a bearing seat casting structure, including a mounting plate 1, a convex strip 2, a first connecting plate 3, a second connecting plate 4 and a cover shell 5. The mounting plates 1 are arranged in pairs and can cooperate with each other. The opposite surfaces of the mounting plates 1 are concavely formed with a mounting groove 101 for accommodating a bearing ring and a through hole 102 for accommodating a connecting shaft. The axis of the mounting groove 101 coincides with the axis of the through hole 102. The mounting groove 101 is located on the opposite surface of the mounting plate 1. A convex strip 2 is formed on the side of the mounting plate 1. The first connecting plate 3 is located on the left and right sides of the mounting plate 1. Screw holes are provided on the first connecting plate 3 and the screw holes on the first connecting plate 3 are respectively located at the first The two sides of the connecting plate 3 are distributed symmetrically, and the cover shell 5 covers the side of the mounting plate 1 in an ] shape. The contact surface between the cover shell 5 and the mounting plate 1 is concave to form a groove 501 matching the convex strip 2. The convex strip 2 is located on the left and right sides of the mounting plate 1. The groove 501 and the convex strip 2 constitute a moving pair in the height direction of the mounting plate 1. The left and right sides of the cover shell 5 are respectively formed with a second connecting plate 4, and the second connecting plate 4 is provided with a screw hole and the bottom surface of the second connecting plate 4 can be against the top surface of the first connecting plate 3. The first connecting plate 3 and the second connecting plate 4 have the same area and the screw hole on the first connecting plate 3 corresponds to the position of the screw hole on the second connecting plate 4.
[0021] Working principle: The bearing ring is set in the installation groove 101 and the connecting shaft passes through the through hole 102. The installer matches the mounting plate 1 so that the mounting groove 101 surrounds both sides of the bearing ring, and sets the cover 5 on the mounting plate 1 so that the cover 5 can clamp the convex strip 2 to limit the mounting plate 1. Then the installer uses bolts to connect the first connecting plate 3 and the second connecting plate 4 and fix them to the mounting surface to complete the installation of the bearing seat.
[0022] The bearing ring is fixed by the mounting grooves 101 on both sides of the bearing ring. The rotation of the bearing ring is limited by the mounting grooves 101, and the amount of runout is small, which does not easily cause the bearing ring to loosen on the bearing seat, helping to reduce the wear of the bearing ring and ensure the stable operation of the bearing ring.
