The bearing seat can rotate at a certain angle on the floating base, thereby facilitating the adjustment of the bearing angle and facilitating the alignment of the shaft. However, the bearing seat is free on the floating base. During the operation of the bearing, the load at various angles may cause the bearing seat to shake, thereby affecting the stability of the transmission and easily damaging the bearing seat.

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0021] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned direction words are not used to limit the present invention.

[0022] See also Figure 1-4 , the utility model provides the following technical solutions:

[0023] A floating bearing seat includes a base 1, an upper cover 2 is installed on the base 1, an inner ring 3 is connected to the base 1 and the upper cover 2 for common rotation, four adjusting screws 5 are threadedly connected to the base 1, and the four adjusting screws 5 are symmetrically distributed at both ends of the inner ring 3, the adjusting screws 5 and the axis of the ring surface of the base 1 are arranged in the same direction, the axis of the adjusting screw 5 and the axis of the inner ring 3 are in the same horizontal plane, the adjusting screw 5 is set to a hemispherical shape at one end facing the inner ring 3, and the hemispherical shape abuts against the end face of the inner ring 3, and the adjusting screw 5 is rotated accordingly to change the length of the adjusting screw 5 extending into the base 1, which can push the inner ring 3 to rotate, and the installation requirements when the shaft body is deflected can be adapted by adjusting the angle of the inner ring 3;

[0024] The outer ring surface of the inner ring 3 is symmetrically arc-shaped, and the radius of the outer ring surface of the inner ring 3 is equal to the radius of the ring surface of the base 1. That is, during the rotation of the inner ring 3, there is always a complete ring line connected to the ring surface of the base 1 and the upper cover 2, ensuring stable support for the inner ring 3.

[0025] Four adjustment grooves 31 are provided on the end face of the inner ring 3. The adjustment grooves 31 are arranged radially. The center plane of the adjustment groove 31 is in the same horizontal plane as the axis of the inner ring 3. The four adjustment grooves 31 are symmetrically arranged on the two end faces of the inner ring 3. The four adjustment grooves 31 are symmetrically arranged about the vertical plane where the axis of the ring surface of the base 1 is located. The adjusting screw 5 is correspondingly abutted against the adjusting groove 31. When the length of the adjusting screw 5 extending into the base 1 changes, it can slide in the adjusting groove 31. The adjusting groove 31 limits the adjusting screw 5 to move only along a fixed radial direction on the inner ring 3, thereby ensuring the reliability of the adjustment screw 5 in adjusting the rotation angle of the inner ring 3. When the four adjusting screws 5 squeeze the inner ring 3 from four positions, the position of the inner ring 3 is fixed.

[0026] The upper and lower ends of the inner ring 3 are connected with a rotating shaft 32, and the two rotating shafts 32 are rotatably connected to the base 1 and the upper cover 2 respectively, thereby fixing the position of the inner ring 3. Two clamping screws 4 are installed on the base 1 and the upper cover 2, and the clamping screws 4 can abut against the rotating shaft 32. The two clamping screws 4 on the base 1 are a group, and the two clamping screws 4 on the upper cover 2 are another group. The two clamping screws 4 in the same group are symmetrically arranged about the corresponding rotating shaft 32. When the clamping screws 4 are rotated, the two clamping screws 4 in the same group press the same rotating shaft 32 from both sides respectively, and the rotation of the rotating shaft 32 is limited by friction. Combined with the self-locking effect of the above-mentioned adjusting screw 5, the stability of the inner ring 3 is improved.

[0027] The clamping screw 4 includes a stud 41, which is arranged along the radial direction of the rotating shaft 32. The stud 41 is correspondingly threadedly connected to the base 1 or the upper cover 2. The end of the stud 41 pointing to the rotating shaft 32 is rotatably connected to an extrusion block 42, and the extrusion block 42 can slide radially along the rotating shaft 32. The side of the extrusion block 42 facing the rotating shaft 32 is arc-shaped, and the radius of the arc is equal to the radius of the rotating shaft 32. A rubber layer 43 is attached to the side of the extrusion block 42 facing the rotating shaft 32. When the stud 41 is rotated, the extrusion block 42 can be pushed to tighten or loosen the rotating shaft 32, which is convenient for adjusting and fixing the angle of the inner ring 3.

[0028] The clamping screw 4 and the adjusting screw 5 can both be set as countersunk screws, which do not extend out of the outside of the base 1 and the upper cover 2 during installation, thereby avoiding scratches and preventing external force from accidentally rotating the screws and affecting the position of the inner ring 3.

[0029] Specifically, an inner ring 3 is provided between the base 1 and the upper cover 2. The inner ring 3 is used to install the bearing. The upper and lower ends of the inner ring 3 are rotatably connected to the bearing seat through a rotary shaft 32. Four adjusting screws 5 are threadedly connected to the base 1. The four adjusting screws 5 are symmetrically arranged on the two end faces of the inner ring 3. The axis of the adjusting screw 5 is on the same horizontal plane as the axis of the inner ring 3. By changing the length of the corresponding adjusting screw 5 extending into the base 1, the inner ring 3 can be pushed to rotate through a certain angle. The adjusting screw 5 itself has a certain self-locking ability. When the four adjusting screws 5 press the inner ring 3 against each other, the position of the inner ring 3 is fixed and will not be offset due to the vibration of the shaft during operation, thereby ensuring the stability of the overall operation and extending the service life of the equipment.

[0030] Two clamping screws 4 are provided on the base 1 and the upper cover 2. The two clamping screws 4 can press the corresponding rotating shaft 32 from both sides. A rubber layer 43 is attached to the side where the clamping screw 4 is connected to the rotating shaft 32, which can prevent the rotating shaft 32 from rotating. Together with the adjusting screw 5, the stability of the inner ring is improved and the overall service life of the equipment is extended.
