However, in practical matching, the inner diameter of the bearing is an upper tolerance, the outer diameter of the linear bearing is a lower tolerance, the two bearings are sometimes too loose when matched, and the gap is too large, so that the accuracy of the usability can be affected in use. When the inner diameter of the bearing is a lower tolerance, the linear bearing is an upper tolerance, and the two are matched tightly without gaps, so that excessive energy is consumed in use, the surface roughness of the outer diameter of the linear bearing is easily damaged, and the service performance of the linear bearing is also affected. Meanwhile, even if the precision of the linear bearing and the bearing seat is very high, the inner diameter gap between the shaft and the bearing seat is increased due to the abrasion between the original linear bearing and the bearing seat after the linear bearing and the bearing seat are used for a period of time, so that vibration and noise occur in the motion process, the linear precision can not be ensured even, the service life is shortened, and the service life of other parts of the whole machine is also influenced.

Detailed Description
Specific embodiments of the present invention are described in further detail below. It should be understood that the description herein of the embodiments of the invention is not intended to limit the scope of the invention.
Fig. 1 to fig. 4 are schematic structural diagrams of a linear bearing system with a pre-tightening and anti-backlash function according to a first practical embodiment of the present invention. The linear bearing system with the pre-tightening and anti-backlash functions comprises a bearing mounting seat 10 and a linear bearing 20 arranged in the bearing mounting seat 10. It is conceivable that the linear bearing system with the pretension anti-backlash function further includes other functional modules, such as a shaft disposed in the linear bearing 20, a lubricating oil or the like disposed between the linear bearing 20 and the shaft, which are known to those skilled in the art, and will not be described herein.
The bearing mounting seat 10 comprises a through hole 11 and a clamping groove 12 arranged on the through hole 11. It is contemplated that the bearing mount 10 also includes some other functional structure, such as mounting structures for the mounting of the bearing mount 10 to a use application, etc., which will not be described in detail herein. The through hole 11 is used for assembling the linear bearing 20, and thus, the diameter of the through hole 11 should be comparable to that of the linear bearing 20. The clamping groove 12 is used for assembling the linear bearing 20. In order to accurately mount the linear bearing 20, i.e., to improve the flatness of the linear bearing 20, the central axis of the clamping groove 12 should coincide with the central axis of the through hole 11. The structure and operation of the clamping groove 12 will be described in detail below in connection with the linear bearing 20.
The linear bearing 20 is inserted in the through hole 11 and includes a bearing body 21, a mounting ring 22 sleeved outside the bearing body 21, and at least one seal ring 23 provided at an axial end portion of the bearing body 21. It is conceivable that the linear bearing 20 also comprises other functional modules, such as a process tank or the like, which is arranged outside the bearing body 21. The bearing body 21 includes a body 211, a mounting accommodation groove 212 provided on an outer sidewall of the body 211, at least one seal ring setting position 213 provided on an axial end portion of the body 211, a plurality of junk slots 214 provided on an inner sidewall of the body 211, and a plurality of support beams 215 between any two junk slots 214. The body 211 has a cylindrical shape, and may be made of plastic. The central axis of the mounting groove 212 coincides with the central axis of the through hole 11, and is disposed at a middle position of the outer sidewall of the main body 211, and the depth of the through hole 11 in the radial direction is strictly required, which will be described later together with the locking groove 12 and the mounting ring 22. The number of the mounting grooves 212 may be determined according to practical needs, and in this embodiment, the bearing body 21 is provided with two mounting grooves 212. The seal ring setting bit 213 is used for setting the seal ring 23. In this embodiment, the sealing ring 23 is an O-ring, the sealing ring setting position 213 is groove-shaped, and the sealing ring 23 is fixed on the sealing ring setting position 213. The junk slots 214 are specifically plural and spaced apart, and the extending direction thereof should be parallel to the central axis of the through hole 11. Due to the presence of the flutes 214, a support beam 215 is formed between any two adjacent flutes 214. The support beam 215 is in direct contact with the shaft first. The seal ring setting bit 213 includes a plurality of elastic teeth disposed at intervals, so that the elastic teeth can shrink or return to the original position when an external force is applied. On a section perpendicular to the central axis of the through hole 11, the arc length of the support beam 215 is equal to the arc length of the elastic tooth piece, and is integrally formed.
The mounting ring 22 is telescopically arranged along the radial direction of the through hole 11. Thus, the mounting ring 22 may be a C-ring, as shown in FIG. 1. The mounting ring 22 may also comprise other forms of telescopic structures for the purpose of radial expansion and contraction of the through hole 11. Accordingly, the mounting ring 22 has a plurality of telescopic structures 221 in a circumferential direction thereof. The telescoping structure 221 may be V-shaped, zigzagged, or wavy in cross section perpendicular to the central axis of the mounting ring 22. As shown in fig. 3, the telescopic structure 221 is zigzag-shaped. As shown in fig. 4, the telescopic structure 221 has a wave shape. Since the mounting ring 22 has the above-mentioned telescopic structure, when an external force is applied in the radial direction, the diameter of the mounting ring 22 is reduced, and when the external force is removed, the mounting ring 22 is restored. The minimum diameter of the mounting ring 22 in the original state is larger than the outer diameter of the body 211, so that it can be pushed against the clamping groove 12 of the bearing mounting seat 10 after the external force is removed. The mounting ring 22 should preferably be sized to assemble the bearing mount 10 with the bearing body 21, and in particular, the radial thickness of the mounting ring receiving groove 212 along the through hole 11 is greater than or equal to the maximum radial thickness of the mounting ring 22 along the through hole 11. The radial thickness of the clamping groove 12 along the through hole 11 is smaller than the maximum radial thickness of the mounting ring 22 along the through hole 11. When mounting, the mounting ring 22 is first contracted and accommodated in the mounting ring accommodation groove 212, and then inserted into the through hole 11 of the bearing mount 10 together with the bearing body 21 until the mounting ring 22 is engaged in the engagement groove 12 of the bearing mount 10, and the original diameter of the mounting is restored after the external force is removed. Because the radial thickness of the clamping groove 12 along the through hole 11 is smaller than the maximum radial thickness of the mounting ring 22 along the through hole 11, a part of the mounting ring 22 along the radial direction of the through hole 11 is clamped in the clamping groove 12, and the rest part is accommodated in the mounting ring accommodating groove 212, thereby achieving the purpose of assembling the bearing mounting seat 10 and the bearing body 21 together, and simultaneously enhancing the axial fixation.
The seal ring 23 is an O-ring, which is disposed on the seal ring setting point 213. In this embodiment, the sealing ring 23 also includes two sealing rings. The outer diameter of the sealing ring 23 is larger than the diameter of the through hole 11, so that when the sealing ring 23 is inserted into the through hole 11, the sealing ring 23 presses the sealing ring setting bit 213 toward the center of the through hole 11, thereby pressing the sealing ring setting bit 213 toward the shaft, and eliminating the gap between the bearing body 10 and the shaft. The thickness of the elastic teeth of the bearing body 21 is reduced along with the mutual friction between the shaft and the bearing body 21, but the elastic teeth still can be extruded on the shaft under the action of the sealing ring 23, so that the purpose of further eliminating the gap is achieved, the purpose of prolonging the service life of the bearing can be achieved, and the stability of the linear bearing system can be improved.
Compared with the prior art, the linear bearing system with the pre-tightening and anti-backlash functions provided by the invention has the advantages that the mounting ring 22 is firstly reduced and accommodated in the mounting ring accommodating groove 212 when being mounted, so that the mounting ring 22 and the bearing body 21 are inserted into the through hole 11 of the bearing mounting seat 10 until the mounting ring 22 is clamped into the clamping groove 12 of the bearing mounting seat 10. Because the radial thickness of the clamping groove 12 along the through hole 11 is smaller than the maximum radial thickness of the mounting ring 22 along the through hole 11, a part of the mounting ring 22 along the radial direction of the through hole 11 is clamped in the clamping groove 12, and the rest part is accommodated in the mounting ring accommodating groove 212, so that the purpose of assembling the bearing mounting seat 10 and the bearing body 21 together is achieved. When the bearing body 21 is mounted on the bearing mounting seat 10, the maximum diameter of the sealing ring 23 on the bearing body 21 is larger than the diameter of the through hole 11, so that the sealing ring presses the elastic tooth sheets arranged at intervals and presses the elastic tooth sheets to the shaft to achieve the function of eliminating gaps. The thickness of the elastic teeth of the bearing body 21 is reduced along with the mutual friction between the shaft and the bearing body 21, but the elastic teeth still can be extruded on the shaft under the action of the sealing ring 23, so that the purpose of further eliminating the gap is achieved, the purpose of prolonging the service life of the bearing can be achieved, and the stability of the linear bearing system can be improved.
Fig. 5 is a schematic structural diagram of a linear bearing system with pretension and backlash elimination according to a second embodiment of the present invention. The linear bearing system of the second embodiment is different from the linear bearing system of the first embodiment in the seal ring, and the structure and shape of the seal ring setting bit where the seal ring is provided are different. The linear bearing system of the second embodiment includes a bearing mount 30, and a linear bearing 40 disposed on the bearing mount 30. The linear bearing 40 includes a bearing body 41, and two seal rings 42 provided at both end portions of the bearing body 41. The two ends of the bearing body 41 are provided with two sealing ring setting bits 411 respectively arranged at the two ends of the bearing body 41. The seal ring setting position 411 is used for installing and fixing the seal ring 42, so that the structure of the seal ring setting position 411 should be matched with the structure of the seal ring 42. The cross section of the sealing ring 42 is square and comprises a clamping groove 421. The seal ring setting bit 411 is L-shaped. The bearing body 41 further includes a clamping ring 412 coupled to the clamping groove 421. When the seal ring 42 is mounted, the locking groove 421 of the seal ring 42 is locked into the locking ring 412, thereby fixing the relative position of the seal ring 42 and the bearing body 41.
The above is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions or improvements within the spirit of the present invention are intended to be covered by the claims of the present invention.
