[0002] Double-row tapered roller bearings are double-row roller bearings with tapered raceways, which include two inner rings arranged opposite to each other, an outer ring sleeved outside the two inner rings, and rolling elements arranged between the inner rings and the outer rings. Since double-row tapered roller bearings have two inner rings, a corrugated retaining spring needs to be arranged between the two inner rings to increase the stability of the two inner rings.
[0003] In the related art, the corrugated circumferential spring is in an arc shape and has a plurality of arc segments and protruding segments between the arc segments along its circumference. The protruding segments are protruding toward the outside of the corrugated circumferential spring, and the protruding segments are provided with connecting grooves extending to the arc segments. The ends of the two inner rings close to each other are provided with annular grooves, and the groove walls of the annular grooves are provided with accommodating grooves so that convex ribs are formed at the ends of the inner rings. After the corrugated circumferential spring is installed on the inner ring, the protruding segments are located in the annular grooves, and the convex ribs on the inner rings are located in the connecting grooves, so that the corrugated circumferential spring limits the two inner rings. However, since the corrugated circumferential spring has a plurality of protruding segments, the corrugated circumferential spring is easily deformed, which affects the connection stability between the corrugated circumferential spring and the inner ring, and further affects the limiting effect of the corrugated circumferential spring on the inner ring. Utility Model Content
[0004] The present application provides a corrugated retaining spring with interlocked ends to increase the connection stability between the corrugated retaining spring and the inner ring and to increase the limiting effect of the corrugated retaining spring on the inner ring.
[0005] The technical solution adopted in this application is:
[0006] A corrugated retaining spring with interlocked ends, comprising a retaining spring body, wherein the retaining spring body has an arc segment and a protruding segment located between the arc segments along its own circumference, the protruding segment is arranged to protrude toward the outside of the retaining spring body, and the protruding segment is provided with a connecting groove extending to the arc segment, the retaining spring body has a separation groove and swinging ends located on both sides of the separation groove, both of the two swinging ends are extended with connecting parts overlapping in the circumferential direction of the retaining spring body, and the two connecting parts can be interlocked under the action of the inner ring and the shaft to limit the relative movement of the two swinging ends in the circumferential direction of the retaining spring body.
[0007] By adopting the above technical solution, when installing the corrugated retaining spring, first press the connecting part located on the inner side so that the retaining spring body is deformed under the action of the connecting part, so that the two connecting parts are separated and the diameter of the retaining spring body changes. Then, the swinging end corresponding to the connecting part located on the outer side is installed in the inner ring, and then pressing force is applied to the retaining spring body along the circumference of the retaining spring body so that the retaining spring body is gradually engaged with the inner ring along its circumference, and finally the two connecting parts are overlapped in the circumference of the retaining spring body, thereby completing the installation of the corrugated retaining spring to the inner ring.
[0008] After the bearing with the corrugated retaining spring in the present application is installed on the shaft, the shaft applies pressure toward the inner ring on the connection part, and the inner ring applies force toward the shaft on the connection part, so that the two connection parts are interlocked under the mutual squeezing action of the inner ring and the shaft, so as to increase the connection stability of the two swinging ends, thereby preventing the two swinging ends from moving in the direction of approaching or moving away from each other in the circumferential direction of the retaining spring body, so as to avoid the situation where the retaining spring is easily deformed, thereby increasing the connection stability between the corrugated retaining spring and the inner ring, so as to ensure the limiting effect of the corrugated retaining spring on the inner ring.
[0009] Optionally, each of the connecting parts has a fixed end connected to the corresponding swing end and a free end opposite to the fixed end, and the thickness of the fixed end is smaller than the thickness of the free end.
[0010] By adopting the above technical solution, since each connecting part has a fixed end and a free end, and the thickness of the fixed end is smaller than the thickness of the free end, the two connecting parts can be interlocked under the action of the inner ring and the shaft, so as to avoid the situation where the retaining spring is easily deformed after the bearing with the corrugated retaining spring in the present application is installed on the shaft, thereby increasing the connection stability between the corrugated retaining spring and the inner ring, and further increasing the limiting effect of the retaining spring on the inner ring.
[0011] Optionally, the thickness of the connecting portion gradually increases from the fixed end to the free end, so that the thickness of the fixed end is smaller than the thickness of the free end.
[0012] By adopting the above technical solution, since the thickness of the connecting part gradually increases from the fixed end to the free end, the area of mutual extrusion and fit of the connecting parts is increased, so as to further increase the connection stability of the two connecting parts, thereby further increasing the annular structure stability of the corrugated retaining spring.
[0013] Optionally, the connecting portion includes a fixed section and a free section, the thickness of the fixed section is smaller than the thickness of the free section, the end of the fixed section away from the free section forms the fixed end, and the end of the free section away from the fixed section forms the free end.
[0014] By adopting the above technical solution, since the thickness of the fixed section is less than the thickness of the free section, after the two connecting parts are matched together, the ends of the two free sections stop and match each other to increase the connection stability of the two swinging ends, thereby avoiding the two swinging ends from moving away from each other in the circumferential direction of the circumferential spring body, thereby increasing the connection stability of the corrugated circumferential spring and the inner ring. At the same time, since the ends of the two free sections stop and match each other, the connection stability of the two swinging ends is further increased.
[0015] Optionally, the sum of the thicknesses of the two connecting parts is equal to the thickness of the retaining spring body, and the inner side of one of the connecting parts is flush with the inner side of the corresponding swing end, and the outer side of the other connecting part is flush with the outer side of the corresponding swing end.
[0016] By adopting the above technical solution, since the sum of the thicknesses of the two connecting parts is equal to the thickness of the retaining spring body, and the inner side of one of the connecting parts is flush with the inner side of the corresponding swinging end, and the outer side of the other connecting part is flush with the outer side of the corresponding swinging end, the two connecting parts are arranged on the sides facing away from each other and flush with the inner side and the outer side of the retaining spring body, respectively, to avoid the situation where the connecting parts protrude from the side of the retaining spring body and affect the installation of the bearing equipped with the corrugated retaining spring in the present application, so as to ensure the effect of facilitating the installation of the bearing, and at the same time ensure the contact area between the bearing and the shaft, so as to ensure the connection stability between the bearing and the shaft.
[0017] Optionally, each of the connecting parts has a fixed end connected to the corresponding swing end and a free end opposite to the fixed end, and transition arc surfaces are provided on opposite sides of the free end.
[0018] By adopting the above technical solution, since transition arc surfaces are provided on both sides of the free end, when the corrugated retaining spring is installed, the side of the free end can form an avoidance with the swing end, so as to achieve the effect of facilitating the installation of the corrugated retaining spring, thereby improving the installation efficiency of the corrugated retaining spring and reducing the difficulty of assembling the corrugated retaining spring.
[0019] Optionally, a height H of the protruding section protruding from the arc-shaped section and a thickness D of the retaining ring body satisfy: D≤H≤2D.
[0020] By adopting the above technical solution, if the height H of the protruding section protruding from the arc section is set to be less than the thickness D of the circlip body, it will affect the clamping effect of the protruding section and the rib on the inner ring, thereby affecting the connection stability of the corrugated circlip and the inner ring; if the height H of the protruding section protruding from the arc section is set to be greater than 2 times the thickness D of the circlip body, it will cause the protruding height of the protruding section and the arc section to be higher, thereby increasing the difficulty of installing the corrugated circlip, thereby affecting the installation efficiency of the corrugated circlip. Setting the height H of the protruding section protruding from the arc section to be greater than or equal to the thickness D of the body and less than or equal to 2 times the thickness D of the circlip body can ensure the connection stability of the corrugated circlip and the inner ring on the one hand, and ensure the installation efficiency of the corrugated circlip on the other hand.
[0021] Optionally, a length L1 of the protruding section in the circumferential direction of the retaining spring body and a length L2 of the arc section in the circumferential direction of the retaining spring body satisfy: L2≤L1≤2L2.
[0022] By adopting the above technical solution, if the length L1 of the protruding section in the circumferential direction of the circumferential spring body is set to be less than L2, the number of protruding sections will be large, which will increase the difficulty of installing the corrugated circumferential spring, and the length of each arc section will be shorter, which will affect the elastic effect of the corrugated circumferential spring; if the length L2 of the protruding section in the circumferential direction of the circumferential spring body is set to be greater than 2 times of L2, the number of protruding sections will be small, and then the limiting position of the corrugated circumferential spring and the inner ring will be reduced, thereby affecting the limiting effect of the corrugated circumferential spring on the inner ring. Setting the length L1 of the protruding section in the circumferential direction of the circumferential spring body to be greater than or equal to the length L2 of the arc section in the circumferential direction of the circumferential spring body and less than or equal to 2 times the length L2 of the arc section in the circumferential direction of the circumferential spring body can ensure the limiting position of the corrugated circumferential spring and the inner ring on the one hand, so as to increase the limiting effect of the corrugated circumferential spring on the inner ring, and on the other hand, it can ensure the effect of facilitating the installation of the corrugated circumferential spring, so as to ensure the installation efficiency of the corrugated circumferential spring.
[0023] Optionally, the connecting groove is located at a middle position of the retaining ring body in the axial direction.
[0024] By adopting the above technical solution, since the connecting groove is located in the middle position of the axial direction of the retaining spring body, after the corrugated retaining spring is installed on the bearing, the corrugated retaining spring is symmetrically arranged about the connecting seam between the two inner rings, so that the bearing is subjected to balanced force in its own axial direction, thereby ensuring the service life of the bearing installed with the corrugated retaining spring in this application.
[0025] Optionally, the width W1 of the connecting groove and the width W2 of the retaining ring body satisfy: 1 / 3W2≤W1≤2 / 3W2.
[0026] By adopting the above technical solution, if the width W1 of the connection groove is set to be less than 1 / 3 times the width W2 of the circlip body, the width of the connection groove will be smaller, and then the width of the rib on the inner ring will be smaller, thereby affecting the structural strength of the rib on the inner ring, and further affecting the connection stability between the corrugated circlip and the inner ring; if the width W1 of the connection groove is set to be greater than 2 / 3 times the width W2 of the circlip body, the width of the connection groove will be larger, and then the structural strength of the corrugated circlip will be affected, and further affecting the limiting effect of the corrugated circlip on the inner ring. Setting the width W1 of the connection groove to be greater than or equal to 1 / 3 times the width W2 of the circlip body and less than or equal to 2 / 3 times the width of the circlip body can ensure the connection stability between the corrugated circlip and the inner ring on the one hand, and ensure the structural strength of the corrugated circlip on the other hand, and further ensure the limiting effect of the corrugated circlip on the inner ring.

[0029] 2. Each connecting part in the present application has a fixed end connected to the corresponding swinging end and a free end opposite to the fixed end.

[0045] Reference Figures 1 to 6 , discloses a corrugated retaining spring with interlocked ends, which includes a retaining spring body 1, the retaining spring body 1 has an arc segment 11 and a protruding segment 12 located between the arc segments 11 along its own circumference, the protruding segment 12 is protruding toward the outside of the retaining spring body 1, and the protruding segment 12 is provided with a connecting groove 121 extending to the arc segment 11, the retaining spring body 1 has a separation groove and swing ends located on both sides of the separation groove, the two swing ends are both extended with connecting parts 111 overlapping in the circumferential direction of the retaining spring body 1, the two connecting parts 111 can be interlocked under the action of the inner ring and the shaft to limit the relative movement of the two swing ends in the circumferential direction of the retaining spring body 1.
[0046] When installing the corrugated retaining spring, first press the connecting part 111 located on the inner side so that the retaining spring body 1 is deformed under the action of the connecting part 111, and then the two connecting parts 111 are separated. At the same time, the diameter of the retaining spring body 1 changes, and then the swing end corresponding to the connecting part 111 located on the outer side is installed in the inner ring, and then pressing force is applied to the retaining spring body 1 along the circumference of the retaining spring body 1, so that the retaining spring body 1 is gradually engaged with the inner ring along its circumference, and finally the two connecting parts 111 overlap in the circumference of the retaining spring body 1, thereby completing the installation of the corrugated retaining spring to the inner ring.
[0047] After the bearing with the corrugated retaining spring in the present application is installed on the shaft, the shaft applies pressure toward the inner ring on the connection part 111, and the inner ring applies force toward the shaft on the connection part 111, so that the two connection parts 111 are interlocked under the mutual squeezing action of the inner ring and the shaft, so as to increase the connection stability of the two swinging ends, thereby preventing the two swinging ends from moving toward or away from each other in the circumferential direction of the retaining spring body 1, so as to avoid the situation where the retaining spring is easily deformed, thereby increasing the connection stability between the corrugated retaining spring and the inner ring, so as to ensure the limiting effect of the corrugated retaining spring on the inner ring.
[0048] It should be noted that the overlapping arrangement of the two connecting portions 111 means that the two connecting portions 111 are overlapped in the radial direction of the retaining spring body 1, that is, one of the connecting portions 111 is arranged on the inner side of one of the swing ends, and the other connecting portion 111 is arranged on the outer side of the other swing end.
[0049] In a preferred embodiment, referring to Figure 3 and Figure 5 Each connecting portion 111 has a fixed end connected to the corresponding swing end and a free end opposite to the fixed end. The thickness of the fixed end is smaller than the thickness of the free end, so that the two connecting portions 111 can be interlocked under the action of the inner ring and the shaft to avoid the situation where the retaining spring is easily deformed after the bearing with the corrugated retaining spring in the present application is installed on the shaft, thereby increasing the connection stability of the corrugated retaining spring and the inner ring, and further increasing the limiting effect of the retaining spring on the inner ring.
[0050] It should be noted that after the bearing is installed on the shaft, the gap between the groove wall of the annular groove on the inner ring and the shaft is constant. Since the thickness of the free end is greater than the thickness of the fixed end, when the two overlapping connecting parts 111 move away from each other, the distance between the end faces of the two connecting parts 111 that are away from each other tends to gradually increase, while the gap between the groove wall of the annular groove and the shaft is constant, so that the inner ring and the shaft squeeze the two connecting parts 111 against each other to achieve interlocking of the two connecting parts 111.
[0051] The present application does not specifically limit the manner in which the thickness of the free end is greater than the thickness of the fixed end, and any one of the following embodiments may be adopted:
[0052] Embodiment 1, in this embodiment, refer to Figure 2 and Figure 3 The thickness of the connecting portion 111 gradually increases from the fixed end to the free end, so that the thickness of the fixed end is smaller than the thickness of the free end, thereby increasing the area of mutual extrusion and matching of the connecting portions 111, so as to further increase the connection stability of the two connecting portions 111, and further increase the annular structure stability of the corrugated retaining spring.
[0053] Embodiment 2, in this embodiment, refer to Figure 5 The connection part 111 includes a fixed section 112 and a free section 113. The thickness of the fixed section 112 is smaller than that of the free section 113. The end of the fixed section 112 away from the free section 113 forms a fixed end, and the end of the free section 113 away from the fixed section 112 forms a free end. After the two connection parts 111 are matched together, the ends of the two free sections 113 stop and cooperate with each other to increase the connection stability of the two swinging ends, thereby avoiding the two swinging ends from moving away from each other in the circumferential direction of the circumferential spring body 1, thereby increasing the connection stability of the corrugated circumferential spring and the inner ring. At the same time, because the ends of the two free sections 113 stop and cooperate with each other, the connection stability of the two swinging ends is further increased.
[0054] In a preferred embodiment, referring to Figure 3 and Figure 5 The sum of the thicknesses of the two connecting parts 111 is equal to the thickness of the retaining spring body 1, and the inner side of one of the connecting parts 111 is flush with the inner side of the corresponding swing end, and the outer side of the other connecting part 111 is flush with the outer side of the corresponding swing end, so that the two connecting parts 111 are flush with the inner side and the outer side of the retaining spring body 1 respectively, so as to avoid the situation where the connecting part 111 protrudes from the side of the retaining spring body 1 and affects the installation of the bearing equipped with the corrugated retaining spring in this application, so as to ensure the effect of facilitating the installation of the bearing, and at the same time ensure the contact area between the bearing and the shaft, so as to ensure the connection stability between the bearing and the shaft.
[0055] In a preferred embodiment, each connecting portion 111 has a fixed end connected to the corresponding swing end and a free end opposite to the fixed end, and transition arc surfaces are provided on both opposite sides of the free end, so that when the corrugated retaining spring is installed, the side of the free end can form an avoidance with the swing end, so as to achieve the effect of facilitating the installation of the corrugated retaining spring, thereby improving the installation efficiency of the corrugated retaining spring and reducing the difficulty of assembling the corrugated retaining spring.
[0056] Preferably, each free end is arc-shaped to ensure the avoidance effect between the free end and the swing end.

[0058] If the height H of the protruding section 12 protruding from the arc section 11 is set to be less than the thickness D of the circlip body 1, the clamping effect between the protruding section 12 and the rib on the inner ring will be affected, thereby affecting the connection stability between the corrugated circlip and the inner ring; if the height H of the protruding section 12 protruding from the arc section 11 is set to be greater than 2 times the thickness D of the circlip body 1, the height of the protruding section 12 protruding from the arc section 11 will be higher, thereby increasing the difficulty of installing the corrugated circlip, thereby affecting the installation efficiency of the corrugated circlip. Setting the height H of the protruding section 12 protruding from the arc section 11 to be greater than or equal to the thickness D of the body and less than or equal to 2 times the thickness D of the circlip body 1 can ensure the connection stability between the corrugated circlip and the inner ring on the one hand, and ensure the installation efficiency of the corrugated circlip on the other hand.
[0059] In a preferred embodiment, referring to Figure 2 , the length L1 of the protruding section 12 in the circumferential direction of the retaining spring body 1 and the length L2 of the arc section 11 in the circumferential direction of the retaining spring body 1 satisfy: L2≤L1≤2L2.
[0060] If the length L1 of the protruding section 12 in the circumferential direction of the retaining spring body 1 is set to be smaller than the length L2 of the arc section 11 in the circumferential direction of the retaining spring body 1, a larger number of protruding sections 12 will result in increasing the difficulty of installing the corrugated retaining spring, and the length of each arc section 11 will be shorter, affecting the elastic effect of the corrugated retaining spring; if the length L2 of the protruding section 12 in the circumferential direction of the retaining spring body 1 is set to be greater than twice the length L2 of the arc section 11 in the circumferential direction of the retaining spring body 1, a smaller number of protruding sections 12 will result in reducing the limiting point between the corrugated retaining spring and the inner ring, thereby affecting the limiting effect of the corrugated retaining spring on the inner ring. The length L1 of the protruding section 12 in the circumferential direction of the retaining spring body 1 is set to be greater than or equal to the length L2 of the arc section 11 in the circumferential direction of the retaining spring body 1 and less than or equal to twice the length L2 of the arc section 11 in the circumferential direction of the retaining spring body 1. On the one hand, it can ensure the limiting position of the corrugated retaining spring and the inner ring to increase the limiting effect of the corrugated retaining spring on the inner ring. On the other hand, it can ensure the effect of facilitating the installation of the corrugated retaining spring to ensure the installation efficiency of the corrugated retaining spring.
[0061] In a preferred embodiment, referring to Figure 6 The connecting groove 121 is located in the middle position of the circlip body 1 in the axial direction, that is, the widths of the protruding sections 12 on both sides of the connecting groove 121 are equal, so that after the corrugated circlip is installed on the bearing, the corrugated circlip is symmetrically arranged about the connecting seam between the two inner rings, so that the bearing is subjected to balanced force in its own axial direction, thereby ensuring the service life of the bearing installed with the corrugated circlip in this application.
[0062] In a preferred embodiment, referring to Figure 6 , the width W1 of the connecting groove 121 and the width W2 of the retaining ring body 1 satisfy: 1 / 3W2≤W1≤2 / 3W2.
[0063] If the width W1 of the connection groove 121 is set to be less than 1 / 3 times the width W2 of the circlip body 1, the width of the connection groove 121 will be smaller, and then the width of the rib on the inner ring will be smaller, thereby affecting the structural strength of the rib on the inner ring, and further affecting the connection stability between the corrugated circlip and the inner ring; if the width W1 of the connection groove 121 is set to be greater than 2 / 3 times the width W2 of the circlip body 1, the width of the connection groove 121 will be larger, and then the structural strength of the corrugated circlip will be affected, and further affecting the limiting effect of the corrugated circlip on the inner ring. Setting the width W1 of the connection groove 121 to be greater than or equal to 1 / 3 times the width W2 of the circlip body 1 and less than or equal to 2 / 3 times the width of the circlip body 1 can ensure the connection stability between the corrugated circlip and the inner ring on the one hand, and ensure the structural strength of the corrugated circlip on the other hand, and further ensure the limiting effect of the corrugated circlip on the inner ring.
