Description

Technical Field

[0001] The utility model relates to the technical field of bearing support, and specifically relates to a compression-resistant and stable bearing seat. Background Art

[0002] Bearings are mainly used between two components, namely a rotating "shaft" and a rotating support member, and have the function of reducing the friction force when the two components rotate. The rotation and support of the bearing require the use of a bearing seat for fixation and support to ensure a certain positional relationship between the bearing and the connecting member. Both support and fixation require the bearing seat to have a compression-resistant and stable effect. The bearing rod and the inner ring are fixed together by fastening an eccentric locking ring along the rotation direction, and the external pressure on the eccentric locking ring achieves the fixation effect.

[0003] However, the external pressure fixation of the eccentric locking ring easily causes the eccentric locking ring to press against the inner ring. Under the rotation of the bearing rod, the eccentric locking ring fixes the outer side of the inner ring of the bearing seat. When the bearing rod rotates eccentrically, lateral rotation movement is likely to occur, and thus the fixation of the eccentric locking ring is prone to looseness and instability. Moreover, the offset force during the rotation of the bearing rod easily causes a rotational difference between the eccentric locking ring and the inner ring, resulting in mutual friction, and thus gaps are likely to appear, reducing the stability. Content of the Utility Model

[0004] The utility model provides a compression-resistant and stable bearing seat, which overcomes the deficiencies described in the background art.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A compression-resistant and stable bearing seat includes a support member, a base, a shroud, a threaded ring, and a threaded rod. The base is fixed on a plane by screwing the screw rods through the threaded rings on both sides. The shrouds on both sides of the support member are arranged on the surface of the base to support both sides of the support member. When the bearing rod passes horizontally through the inside of the support member, and after the three threaded rods are screwed, they annularly press against the outer side of the bearing rod;

[0007] The support member is provided with balls, an inner ring member, a locking ring, threaded holes, and a fixing ring. The bearing rod passes through the inside of the inner ring member and the locking ring, and after the locking ring is pressed, it rotates and is fixed on the side of the inner ring member. Moreover, the threaded rod is screwed through the threaded hole at the position of the locking ring and presses against the outer side of the bearing rod for fixation. When the bearing rod rotates, the bearing rod drives the inner ring member and the locking ring to rotate synchronously, and the inner ring member rotates in a limited manner on the balls inside the fixing ring;

[0008] The inner ring member and the locking ring are located on the same central axis position, and the inner diameter of the inner wall of the inner ring member is larger than the inner diameter of the inner wall of the locking ring. When the bearing rod deviates unstably, the locking ring drives the deviation force of the bearing rod to evenly act on the inner ring member again, and buffers the offset force of the bearing rod on the inner ring member.

[0009] A better technical solution: the inner ring component is provided with a gap ring, an inner ring plate, a clamping plate, and a feed trough. The feed trough and the clamping plate are distributed in a circular array on the central axis of the inner ring plate. The inner end of the locking ring is inserted into the three feed trough positions, and the locking ring is rotated to slide from the gap ring into the three clamping plate positions for limiting.

[0010] A better technical solution: the feed trough is a square opening structure, the three feed troughs match the corresponding inner ends of the locking rings, and the gap rings are located on the left and right sides of the feed trough, and the size of the gap rings matches the corresponding locking rings.

[0011] A better technical solution: the locking ring is provided with a stress ring, an elastic metal rod, and an annular plate. The stress ring is arranged on the outside of the elastic metal rod. The elastic metal rods are distributed in an annular array on the side of the annular plate. The three stress rings and the elastic metal rods correspond to the three feed troughs.

[0012] A better technical solution: the clamping plate is arranged on the inner plane of the inner ring plate. The clamping plate has arc-shaped protrusions on both sides and a sunken structure in the middle. The upper layer of the clamping plate is made of metal and the lower layer is made of rubber. It has the characteristic of high pressure. When the force ring slides into the clamping plate in the feed trough, its twisting resistance is relatively large.

[0013] Compared with the prior art, this technical solution has the following advantages:

[0014] In the utility model, the bearing rod passes through the supporting member, and the locking ring is rotated to be engaged and fixed with the inner ring member, and the bearing rod inside the locking ring is fixedly pressed at the screw hole position. When the bearing rod is laterally offset, the locking ring pushes and pulls the inner ring member laterally under the lateral force of the bearing rod. Since the inner ring member and the locking ring are in a fixed engaging state, the locking ring and the inner ring member rotate synchronously, and the bearing rod is limited and fixed on the inner side of the inner ring member to prevent lateral offset.

[0015] The three stress rings in the lock ring of the utility model enter from the three feed grooves, and the annular plate is rotated to make the three elastic metal rods slide in the feed groove, so that the three stress rings reach the three corresponding clamping plates and are squeezed and clamped, and frictionally supported in the three clamping plates. When the bearing rod moves laterally, the lateral force generated by the stress ring at the clamping plate position is blocked by the inner ring plate, and the rotational force of the annular plate driven by the bearing is frictionally blocked by the arc-shaped protrusion of the clamping plate, so that the lock ring is limited and fixed on the inner side of the inner ring part, and when disassembling, the annular plate is pressed inward to make the vertical surface of the stress ring separate from most of the clamping plate positions to reduce friction, so that the lock ring is easy to rotate and screw out again, and then when the bearing rod rotates off the center, the lock ring is stable in buffering the eccentric force.

Specific implementation manner

[0023] As Figures 1 to 5 shown, a compression - resistant and stable bearing seat is proposed in the present utility model, which includes a support member 1, a base 2, an enclosing plate 3, a threaded ring 4, and a threaded rod 5. The base 2 is fixed on a plane by screwing a screw through the threaded rings 4 on both sides. The enclosing plates 3 on both sides of the support member 1 are arranged on the surface of the base 2 to support both sides of the support member 1. When a bearing rod horizontally passes through the inside of the support member 1, and the three threaded rods 5 are screwed, they annularly press against the outer side of the bearing rod;

[0024] The support member 1 is provided with balls 11, an inner ring member 12, a locking ring 13, a screw hole 14, and a fixing ring 15. The bearing rod passes through the inside of the inner ring member 12 and the locking ring 13, so that the locking ring 13 is rotated and fixed on the side surface of the inner ring member 12 after being pressed, and the threaded rod 5 is screwed through the screw hole 14 and passes through the locking ring 13 to press against the outer side of the bearing rod for fixation. When the bearing rod rotates, the bearing rod drives the inner ring member 12 and the locking ring 13 to rotate synchronously, and the inner ring member 12 is rotationally limited on the balls 11 inside the fixing ring 15;

[0025] The inner ring member 12 and the locking ring 13 are located on the same central axis position, and the inner diameter of the inner wall of the inner ring member 12 is larger than the inner diameter of the inner wall of the locking ring 13. When the bearing rod deviates unstably, the locking ring 13 drives the deviation force of the bearing rod to uniformly act on the inner ring member 12 again, and buffers the offset force of the bearing rod on the inner ring member 12.

[0026] Among them, the inner ring member 12 is provided with a clearance ring 121, an inner ring plate 122, a clamping plate 123, and a feeding groove 124. The feeding groove 124 and the clamping plate 123 are annularly and arrayedly distributed on the central axis of the inner ring plate 122. The inner end of the locking ring 13 is inserted at the positions of the three feeding grooves 124, and the locking ring 13 is rotated to slide it from the clearance ring 121 into the positions of the three clamping plates 123 for limiting.

[0027] When the present utility model is installed, the bearing rod passes through the inner ring member 12 and the locking ring 13, and the locking ring 13 is installed on the side of the inner ring member 12. And the three threaded rods 5 pass through the screw holes 14 and press against the outer side of the bearing rod. Wherein, the locking ring 13 forms a rotational resistance at the position of the clamping plate 123, so that the supporting effect of the locking ring 13 on the bearing rod acts inside the inner ring plate 122. When there is a lateral offset, the locking ring 13 laterally slides on the gap at the position of the clamping plate 123. Furthermore, the locking ring 13 buffers a certain lateral offset force to avoid instability caused by lateral offset.

[0028] Among them, the feeding groove 124 is of a square opening structure. The three feeding grooves 124 are in correspondence with the inner ends of the locking ring 13, and the clearance ring 121 is located on the left and right sides of the feeding groove 124. The size of the clearance ring 121 corresponds to and fits with the locking ring 13.

[0029] Among them, the locking ring 13 is provided with a force-receiving ring 131, elastic metal rods 132, and an annular plate 133. The force-receiving ring 131 is arranged on the outer side of the elastic metal rods 132. The elastic metal rods 132 are annularly and arrayedly distributed on the side of the annular plate 133. The three force-receiving rings 131 correspond to the three feeding grooves 124 of the elastic metal rods 132.

[0030] Among them, the clamping plate 123 is arranged on the inner side plane of the inner ring plate 122. The clamping plate 123 is of a structure with two arc-shaped protrusions in the middle and an inward depression. And the upper layer of the clamping plate 123 is made of metal material, and the lower layer is made of rubber material, with the characteristic of large pressure. When the force-receiving ring 131 slides into the clamping plate 123 from the feeding groove 124, its screwing resistance is relatively large.

[0031] In the present utility model, the force-receiving ring 131 on the side of the annular plate 133 is clamped at the position of the clamping plate 123. When the bearing rod rotates deviating from the center, the diameter of the inner ring plate 122 is larger than that of the annular plate 133. Furthermore, the bearing rod is more closely and stably attached at the position of the annular plate 133. When eccentric, the bearing rod drives the annular plate 133 to deviate from the center position. Since the annular plate 133 is fixed inside the inner ring plate 122, and there is also a clearance difference between the annular plate 133 and the inner ring plate 122, the movement range of the bearing rod is limited within the clearance difference. Through the three elastic metal rods 132 being stably clamped inside the clamping plate 123, the eccentric rotation force of the annular plate 133 is blocked and limited by the clamping plate 123, realizing the blocking of the eccentric rotation of the bearing rod and preventing the problem of unstable eccentric rotation of the bearing rod.

[0032] When it is necessary to explain, the fact that the inner ring member 12 and the locking ring 13 in the present utility model are not integrated is to facilitate the bearing rod to pass through the inner ring members 12 and the locking rings 13 of different sizes, so that the eccentric movement range of the bearing rod is between the clearance differences of the inner ring members 12 and the locking rings 13, ensuring that the deviation range will not be too large and is easy to be stabilized. When the bearing rod deviates from the center, the locking ring 13 buffers the eccentric force on the side of the inner ring member 12, avoiding the direct action on the locking ring 13 due to integration and easily causing looseness due to hard impact.

[0033] The above is only a preferred embodiment of the present utility model, and thus the scope of implementation of the present utility model cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present utility model patent and the content of the specification should still fall within the scope covered by the present utility model.
