The natural state of the elastic restoring element 120 refers to a state when the elastic restoring element 120 (the deformation section 122) is not deformed by an external force, as shown in the solid line state of fig. 3; the abutting state of the elastic restoring member 120 refers to a state in which the elastic restoring member 120 (the deformation section 122) is deformed by an external force, as shown by a dotted line state in fig. 3.

Thus, when the elastic reset piece 120 is installed in the installation groove 112, the elastic reset piece 120 can be accurately installed along the radial direction of the bearing 200 by utilizing the positioning fit of the positioning sleeve 140 and the positioning hole 114 and the positioning fit of the threaded piece 130 and the positioning sleeve 140, and it is ensured that the elastic reset piece 120 can apply a contact force to the outer ring 210 of the bearing 200. Wherein the locating sleeve 140 may be in the form of a bushing.

In addition, the opening positions of the mounting grooves 112, the mounting positions of the elastic reset pieces 120, the number of the mounting grooves 112 and the number of the elastic reset pieces 120 can be flexibly adjusted or designed according to the actual working scene, and only the requirement that the outer ring 210 of the bearing 200 can be prevented from generating radial displacement by exerting the abutting force on the outer ring 210 of the bearing 200 is needed. For example, when the bearing seat 100 and the bearing 200 are applied to support a crankshaft of an engine, the piston applies a downward acting force to the connecting rod to push the crankshaft to rotate, so that the bearing 200 is subjected to a large downward radial force, and thus a downward abutting force can be applied to the outer ring 210 of the bearing 200 by using the elastic restoring member 120, and the bearing 200 can be limited from moving radially upwards; of course, since there is a large upward inertial force due to the rotation of the crankshaft, the bearing 200 is also subjected to a large upward radial force, and the elastic restoring member 120 can also be used to apply an upward resisting force to the outer ring 210 of the bearing 200, so as to limit the downward radial play of the bearing 200.

Wherein, the cover body can be fixed on the seat body 110 in a screw joint, riveting, viewing or welding manner. The cover body can be a cover plate or a shielding cover.

As shown in fig. 1, in an embodiment, a bearing transmission structure 10 is further provided, which includes the bearing seat 100 and the bearing 200 of any of the above embodiments, the bearing 200 is disposed in the mounting through hole 111, and an outer wall of an outer ring 210 of the bearing 200 is in interference fit with the elastic restoring member 120.

When the bearing transmission structure 10 of the above embodiment is used, even if the bearing 200 receives the acting force in the radial direction, under the interference action of the elastic reset piece 120, the outer wall of the outer ring 210 opposite to the elastic reset piece 120 can be tightly attached to the inner wall of the installation through hole 111, so that the bearing 200 is limited to move radially, and the generation of abnormal sound caused by the relative motion between the outer wall of the outer ring 210 and the inner wall of the installation through hole 111 is avoided.

As shown in fig. 2, 4 and 5, the outer wall of the outer ring 210 is provided with a first interference slope 211 inclined with respect to the central axis of the bearing 200. The elastic reset element 120 is in interference fit with the first interference inclined plane 211. In this way, the elastic restoring member 120 applies a contact force to the first contact inclined surface 211, so that the outer wall of the outer ring 210 opposite to the elastic restoring member 120 is tightly attached to the inner wall of the mounting through hole 111, and the radial play of the bearing 200 is limited. When the deformation of the bearing 200 and the bearing seat 100 becomes large, resulting in the gap between the outer wall of the outer ring 210 of the bearing 200 and the inner wall of the installation through hole 111 becoming large, the elastic reset piece 120 deforms towards the reset direction (as shown in the F direction of fig. 2), because the distance from the first abutting inclined surface 211 to the central axis of the bearing 200 (as shown in the L direction of fig. 5) increases progressively along the reset direction of the elastic reset piece 120, thereby enabling the elastic reset piece 120 to be always in abutting fit with the first abutting inclined surface 211, ensuring that the elastic reset piece 120 can continue and stably apply the abutting force to the outer ring 210 of the bearing 200, further enabling the outer wall of the outer ring 210 opposite to the elastic reset piece 120 to be closely attached to the inner wall of the installation through hole 111, and being capable of reliably limiting the radial play of the bearing 200 and avoiding the generation of abnormal sound. When the gap between the outer wall of the outer ring 210 of the bearing 200 and the inner wall of the mounting through hole 111 becomes large, in order to ensure that the contact force can be provided to the outer ring 210 even if the elastic restoring member 120 is restored, when the elastic restoring member 120 is restored to the maximum distance from the central axis of the bearing 200, the state of the elastic restoring member 120 is still in an interference state rather than a natural state. The reset direction of the elastic reset element 120 refers to a direction in which the elastic reset element 120 moves from an interference state to a natural state. The first collision inclined surface 211 inclines relative to the central axis of the bearing 200, which means that an included angle between a projection line of the central axis of the bearing 200 on the first collision inclined surface 211 and the central axis of the bearing 200 is alpha, alpha is more than 0 degrees and less than 90 degrees, the size of alpha can be flexibly adjusted according to actual use conditions, and only the requirement that the elastic resetting piece 120 can always apply a contact force to the outer ring 210 is met.

As shown in fig. 2 and fig. 3, a second abutting inclined surface 123 is further disposed at the other end of the elastic restoring element 120, and the second abutting inclined surface 123 is attached to the first abutting inclined surface 211. So, clearance grow between the outer wall of bearing 200's outer lane 210 and the inner wall of installation through-hole 111, when elasticity resets 120 and resets, the second is contradicted inclined plane 123 and is being laminated first conflict inclined plane 211 and slide along the incline direction of first conflict inclined plane 211, has increased elasticity and has reset the area of contact of piece 120 with outer lane 210, guarantees that elasticity resets 120 can be stable, reliable applys to touch power to outer lane 210.
