Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a rolling bearing with an axis adjustment function. Background Art

[0002] At present, bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Traditional bearings are fixed on the bearing seats, and the axis cannot be changed. Once the vertical position of the axis needs to be changed, only the bearing platform fixed to the bearing seat can be adjusted, which has low adjustment efficiency and poor effect.

[0003] Chinese patent publication number CN112664559B discloses a light bearing with a self-aligning function, which relates to the field of bearing technology and includes: a base, a support frame, an adjusting ring, a sleeve, a bearing and a control device; the support frame is vertically arranged on the base, and a circular groove is arranged in the middle of the support frame; the adjusting ring is embedded in the circular groove of the support frame; two elastic devices are relatively arranged on the inner wall of the adjusting ring, and the elastic device includes: a pressure tube and a support rod; the bearing is embedded in the sleeve; the sleeve and the support rod fixing control device is used to control the pressure tube to drive the support rod to extend and retract, so that the axis of the bearing moves along the extension and retraction direction of the support rod.

[0004] The light bearing is provided with a control device and an elastic device so that the bearing can move radially under the drive of the elastic device, thereby changing the axial position of the bearing. However, the support rod in the pressure pipe drives the sleeve to move, which will cause uneven force on the bearing. The uneven force on the bearing sleeve will cause vibration and instability in the bearing during rotation. This may cause the bearing to run unsmoothly and affect the normal operation of the mechanical equipment. Uneven force will cause excessive local stress on the bearing sleeve, which will greatly reduce the fatigue life of this part. If not handled in time, the bearing may be fatigued and damaged prematurely, shortening its service life. Uneven force on the bearing will cause poor contact between the bearing sleeve and the rolling element, increasing the risk of local wear and load concentration. In severe cases, the bearing may be damaged and need to be replaced or repaired. Uneven force on the bearing will cause increased noise and temperature of the bearing during operation. This will affect the normal operation of the equipment and may cause other failures. Utility Model Content

DETAILED DESCRIPTION

[0031] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the rolling bearing with an axis adjustment function of this embodiment includes a bearing seat 1, a bearing body 2, a first adjustment mechanism 3 and a second adjustment mechanism 4; the bearing seat 1 has a circular mounting opening; the first adjustment mechanism 3 is coaxially and rotatably arranged in the mounting opening, and the first adjustment mechanism 3 has a mounting groove 31 extending radially along the mounting opening; the bearing body 2 is slidably arranged in the mounting groove 31; the second adjustment mechanism 4 is coaxially arranged in the first adjustment mechanism 3, and the second adjustment mechanism 4 has a toggle assembly capable of adjusting the position of the bearing body 2 on the mounting groove 31.

[0033] When the radial position of the bearing body 2 relative to the mounting opening needs to be adjusted, the second adjusting mechanism 4 is activated so that the toggle assembly can guide the bearing body 2 to slide in the mounting groove 31, and the mounting groove 31 extends along the radial direction of the mounting opening, thereby adjusting the radial position of the bearing body 2 relative to the mounting opening;

[0034] When it is necessary to adjust the circumferential position of the bearing body 2 relative to the bearing seat 1, the first adjustment mechanism 3 is started. The first adjustment mechanism 3 can drive the bearing body 2 and the first adjustment mechanism 3 to rotate a certain angle relative to the bearing seat 1, thereby changing the bearing body 2 to adjust its circumferential position after adjusting its radial position, thereby improving the adjustment efficiency and effect of the axial position of the bearing body 2.

[0035] In this embodiment, the first adjusting mechanism 3 is arranged in the circular mounting opening of the bearing seat 1, and the second adjusting mechanism 4 is installed in the first adjusting mechanism 3. When the axis center of the bearing body 2 needs to be adjusted, the bearing body 2 can be slid in the mounting groove 31 by moving the assembly, and the mounting groove 31 extends along the radial direction of the mounting opening, so that the bearing body 2 can move along the radial direction of the mounting opening. At the same time, the bearing body 2 can be rotated by the first adjusting mechanism 3 to adjust the axis center position of the bearing body 2. The overall structure is stable, and the bearing sleeve is evenly stressed, which can improve the stability, service life and mechanical efficiency of the bearing, while reducing noise and vibration.

[0036] like Fig. 9 As shown, the rolling bearing further comprises a mounting frame 5, the mounting frame 5 comprises an outer plate 51, an inner plate 52 and a connecting pin 53, the outer plate 51 and the inner plate 52 are respectively slidably arranged on both sides of the mounting groove 31, the bearing body 2 is sandwiched between the outer plate 51 and the inner plate 52, the connecting pin 53 is circumferentially arranged on the outer side of the bearing body 2, the two ends of the connecting pin 53 are respectively connected to the outer plate 51 and the inner plate 52, and the connecting pin 53 is slidably connected to the side of the mounting groove 31. In order to enable the bearing body 2 to slide stably in the mounting groove 31, the outer plate 51 and the inner plate 52 are respectively slidably arranged on both sides of the mounting groove 31, so that the bearing body 2 is sandwiched between the outer plate 51 and the inner plate 52, and the inner plate 52 and the outer plate 51 are connected by the connecting pin 53, so that the inner plate 52 and the outer plate 51 can be disassembled and connected, so that different types of bearing bodies 2 can be installed between the inner plate 52 and the outer plate 51, which is convenient for subsequent disassembly and installation, and has higher practicality.

[0037] When bearings of different sizes can be installed between the inner and outer plates, different working conditions can be adapted: bearings of different sizes are suitable for different load and speed conditions. By installing bearings of different sizes, the needs under different working conditions can be met, and the adaptability and versatility of mechanical equipment can be improved. When the bearing needs to be replaced, bearings of different sizes can be selected for replacement without replacing the entire inner and outer plates. This can save the cost and time of replacing the plates, as well as interference with other components, and improve the flexibility and convenience of maintenance. By selecting the appropriate size of bearings, the use of oversized or undersized bearings can be avoided, reducing material waste and costs. In addition, bearings of different sizes may also differ in price, and more cost-effective bearings can be selected according to actual needs.

[0038] like Figure 4 , Figure 5 and Figure 6 As shown, the first adjustment mechanism 3 includes an adjustment cylinder 32 that is locked and connected to the bearing seat 1 in a unlockable manner, and a fixing plate 33 is provided at one end of the adjustment cylinder 32, and a mounting groove 31 extending in its radial direction is provided on the fixing plate 33. A fixing plate 33 is provided at one end of the adjustment cylinder 32, and a mounting groove 31 extending in its radial direction is provided on the fixing plate 33, so that the bearing body 2 can be stably mounted on the mounting groove 31 through the mounting frame 5.

[0039] When it is necessary to adjust the circumferential position of the bearing body 2, the radial position of the bearing body 2 in the bearing seat 1 is adjusted in advance. In this radial position, the bearing body 2 is rotated so that the axis of the bearing body 2 is moved to an appropriate position. After releasing the lock between the adjustment cylinder 32 and the bearing seat 1, the adjustment cylinder 32 is rotated relative to the bearing seat 1 to adjust the axis of the bearing body 2.

[0040] like Figure 4 and Figure 5 As shown, one end of the mounting opening is provided with a first engaging groove 111 arranged along its circumference, the adjusting cylinder 32 is coaxially slidably arranged in the bearing seat 1, one end of the outer circumferential surface of the adjusting cylinder 32 is provided with a first limiting ring 321, and the other end of the outer circumferential surface of the adjusting cylinder 32 is provided with a first engaging ring 34 that can be engaged with the first engaging groove 111, and a first elastic member 35 is provided between the first limiting ring 321 and the bearing seat 1.

[0041] In the initial state, under the action of the first elastic member 35, the first engaging ring 34 at one end of the adjusting cylinder 32 can be stably engaged with the first engaging groove 111, so that the adjusting cylinder 32 cannot rotate relative to the bearing seat 1, thereby ensuring that the inner ring of the bearing body 2 can stably rotate relative to the bearing seat 1;

[0042] When it is necessary to adjust the circumferential position of the bearing body 2, the adjusting cylinder 32 is slid relative to the bearing seat 1 so that the adjusting cylinder 32 overcomes the elastic force of the first elastic member 35, and the first interlocking ring 34 withdraws from the first interlocking groove 111, thereby enabling the adjusting cylinder 32 to rotate relative to the bearing seat 1. After adjusting the circumferential position of the bearing body 2, the adjusting cylinder 32 is released so that the adjusting cylinder 32 is reset under the action of the first elastic member 35, so that the first interlocking ring 34 and the second interlocking groove are locked, thereby locking the adjusting cylinder 32 after the angle is adjusted to prevent it from rotating.

[0043] like Figure 6 As shown, the outer circumferential surface of the first limiting ring 321 is provided with first grooves distributed along its circumference. By providing the first grooves on the first limiting ring 321, the friction between the operator and the first limiting ring 321 is increased, thereby facilitating the rotation of the adjustment cylinder 32 relative to the bearing seat 1.

[0044] like Figure 4 , Figure 7 and Figure 8 As shown, one end of the inner plate 52 is provided with a first slide groove 521 extending in a direction perpendicular to the sliding direction of the inner plate 52, and the toggle assembly includes a first toggle ring 42 locked and connected to the adjustment cylinder 32 in a manner that can be unlocked, and a first boss 421 extending in its radial direction is provided on the inner circumferential surface of the first toggle ring 42, and a first toggle column 422 is provided on the first boss 421, and the first toggle column 422 extends into the first slide groove 521 and slidably cooperates therewith.

[0045] When it is necessary to move the mounting bracket 5 on the mounting groove 31, after releasing the lock between the first toggle ring 42 and the adjusting cylinder 32, the first toggle post 422 is rotated relative to the adjusting cylinder 32, so that the toggle post rotates along the circumferential direction of the first toggle ring 42, and the toggle post extends into the first slide groove 521 and slides with it, and the first slide groove 521 extends in a sliding direction perpendicular to the inner plate 52, so that the toggle ring can guide the inner plate 52 to move to one side at the center position of the mounting groove 31 when rotating, thereby adjusting the radial position of the mounting bracket 5 in the mounting opening.

[0046] like Figure 8 As shown, one end of the inner plate 52 opposite to the first slide groove 521 is provided with a second slide groove 522 extending in a direction perpendicular to the sliding direction of the inner plate 52, and the toggle assembly also includes a second toggle ring 43 locked and connected to the adjustment cylinder 32 in an unlockable manner, and a second boss 431 extending radially thereof is provided on the inner circumferential surface of the second toggle ring 43, and a second toggle column 432 is provided on the second boss 431, and the second toggle column 432 extends into the second slide groove 522 and slidably cooperates therewith.

[0047] When the first toggle post 422 guides the sliding in the first slide groove 521 and guides the inner plate 52 to slide on one side of the installation groove 31, the inner plate 52 is subjected to force on one side, which will cause uneven force. In order to improve the uniformity of the force on the inner plate 52, a second toggle ring 43 that can be unlocked from it is installed in the adjusting cylinder 32. When the second toggle ring 43 rotates, the second toggle post 432 on the second boss 431 can slide on the second slide groove 522, and the second toggle post 432 can guide the inner plate 52 to slide on the installation groove 31, so that the first toggle post 422 and the second toggle post 432 can synchronously guide the inner plate 52 to move on the side of the installation groove 31, and the overall force on the inner plate 52 is more uniform.

[0048] like Figure 7 and Figure 8 As shown, a first arc-shaped meshing strip 423 is provided at one end of the first shift ring 42 opposite to the second shift ring 43, and a second arc-shaped meshing strip 433 is provided at one end of the second shift ring 43 opposite to the first shift ring 42. A gear 47 with a rotating axis extending radially thereof is provided in the adjusting cylinder 32, and the gear 47 is located between the first shift ring 42 and the second shift ring 43, and the gear 47 meshes with the first arc-shaped meshing strip 423 and the second arc-shaped meshing strip 433.

[0049] When the gear 47 rotates, due to the engagement of the gear 47 with the first arc-shaped meshing strip 423 and the second arc-shaped meshing strip 433, the first toggle ring 42 and the second toggle ring 43 can rotate synchronously in opposite directions, so that the first toggle column 422 and the second toggle column 432 can move upward or downward synchronously, so that the first toggle column 422 and the second toggle column 432 can synchronously guide the inner plate 52 to slide on one side of the mounting groove 31.

[0050] like Figure 8 As shown, one end of the adjusting cylinder 32 is provided with a second meshing groove 322 distributed along its circumference, the inner circumferential surface of the second shifting ring 43 is provided with a fixed cylinder 44 coaxially fixedly connected thereto, the outer end of the fixed cylinder 44 is provided with a second limiting ring 441, the second adjusting mechanism 4 also includes a sliding ring 45 and a second elastic member 46, the sliding ring 45 is coaxially slidably arranged on the outer circumferential surface of the fixed cylinder 44, the second elastic member 46 is arranged between the sliding ring 45 and the second limiting ring 441, the outer circumferential surface of the sliding ring 45 is provided with a connecting cylinder 451 extending along its axial direction, and the outer end of the connecting cylinder 451 is provided with a second interlocking ring 452 capable of interlocking with the second meshing groove 322.

[0051] When it is necessary to rotate the first toggle ring 42 relative to the adjusting cylinder 32, the sliding ring 45 is moved relative to the adjusting cylinder 32, and the second engaging ring 452 connected to the sliding ring 45 through the connecting cylinder 451 can be separated from the second engaging groove 322, so that the second toggle ring 43 can rotate within the adjusting cylinder 32. After releasing the sliding ring 45, the sliding ring 45 is reset under the action of the second elastic member 46, so that the second engaging ring 452 re-engages with the second engaging groove 322, thereby locking the second toggle ring 43 to prevent it from rotating.

[0052] like Figure 4 As shown, the outer circumferential surface of the second engaging ring 452 is provided with second grooves distributed along its circumference. By providing the second grooves on the second limiting ring 441, the friction between the operator and the second limiting ring 441 is increased, thereby facilitating the rotation of the adjusting cylinder 32 relative to the bearing seat 1.

[0053] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
