The adjusting piece 420 is connected with the corresponding sliding bearing tile 2, as shown in fig. 3, the lower end of the adjusting piece 420 is abutted with the upper end of the sliding bearing tile 2 and can slide relatively; the adjusting member 420 is connected to the driving structure 421, and when the driving structure 421 drives the adjusting member 420 to slide along the inclined plane 410, the fixing structure 41 pushes the adjusting member 420 to move downward through the inclined plane 410, so that the adjusting member 420 pushes the sliding bearing bush 2 to move downward, and the distance between the sliding bearing bush 2 and the rotating shaft 3 is reduced.

Through set up adjustment mechanism 4 between bearing frame 1 and sliding bearing tile 2, can adjust the clearance between sliding bearing tile 2 and the pivot 3, make the clearance between sliding bearing tile 2 and the pivot 3 be in suitable within range, guaranteed bearing device's normal operating.

As shown in fig. 3, the coupling member 4211 is coupled to the bearing housing 1, and the coupling member 4211 may be fixedly coupled to the bearing housing 1 or may be coupled to the bearing housing 1 by a bolt. A screw hole is formed in the right end of the connecting piece 4211, an adjusting screw 4210 is sleeved in the screw hole, and the length direction of the adjusting screw 4210 is consistent with the sliding direction of the adjusting piece 420; one end of the adjusting screw 4210 is rotatably connected with the adjusting piece 420, that is, the left end of the adjusting screw 4210 is connected with the right end of the adjusting piece 420, and the adjusting screw 4210 and the adjusting piece 420 can rotate relatively but cannot be separated.

When the adjusting screw 4210 is screwed to rotate, the adjusting screw 4210 moves in the horizontal direction, it should be noted that when the adjusting screw 4210 is rotated clockwise, the adjusting screw 4210 may move horizontally leftwards or horizontally rightwards, and the rotation direction of the adjusting screw 4210 and the horizontal movement direction corresponding to the rotation direction are related to the arrangement of the threads, and can be determined according to the actual situation, and the limitation is not limited herein. When the adjusting screw 4210 moves leftwards, the adjusting piece 420 is driven to slide leftwards along the inclined plane 410, and the adjusting piece 420 moves downwards under the action of the inclined plane 410 to push the sliding bearing bush 2 to move downwards, so that the distance between the sliding bearing bush 2 and the rotating shaft 3 is reduced.

Through setting up connecting piece 4211 and adjusting screw 4210, rotatory adjusting screw 4210 can conveniently realize the regulation of the distance between slide bearing tile 2 and the pivot 3, and the shared space of adjusting screw 4210's structure is less, can not cause the influence to other structures in the bearing device, and is also comparatively convenient during the installation.

It should be noted that, in conjunction with fig. 1, 2 and 3, the adjusting end of the adjusting screw 4210 faces into the gap 33, so that a worker can conveniently enter the gap 33 and rotate the adjusting screw 4210 to adjust the adjusting member 420.

In some embodiments of the present application, a side of the adjusting piece 420 close to the adjusting screw 4210 is provided with a connecting portion 4201, the connecting portion 4201 has an abutment surface 4202 opposite to the end surface 12 of one end of the adjusting screw 4210, one end of the adjusting screw 4210 is provided with an abutment portion 4210a, and the abutment portion 4210a abuts against the abutment surface 4202; a stopper 423 is connected to the adjusting member 420, and the stopper 423 is located on a side of the abutting portion 4210a away from the abutting surface 4202.

As shown in fig. 3, the right end of the adjuster 420 is provided with a connecting part 4201, the right end surface of the connecting part 4201 is an abutment surface 4202, the left end of the adjusting screw 4210 is provided with an abutment portion 4210a, and the abutment portion 4210a abuts against the abutment surface 4202; the limiting piece 423 is disposed at the right end of the connecting portion 4201 of the adjusting piece 420, the limiting piece 423 is located at the right end of the abutting portion 4210a of the adjusting screw 4210, and the limiting piece 423 may be fixedly connected with the connecting portion 4201 or detachably connected with the connecting portion 4201.

When the adjusting screw 4210 moves horizontally leftward, the abutting portion 4210a on the adjusting screw 4210 abuts against the abutting surface 4202 on the connecting portion 4201, the adjusting piece 420 is pushed to move leftward, the adjusting piece 420 moves downward under the action of the inclined surface 410 to push the sliding bearing bush 2 to move downward, and the distance between the sliding bearing bush 2 and the rotating shaft 3 is reduced; when the adjusting screw 4210 moves horizontally to the right, the limiting member 423 prevents the adjusting screw 4210 and the adjusting member 420 from being separated from each other, that is, the adjusting screw 4210 can drive the adjusting member 420 to move horizontally to the right, so that the adjusting structure can be adjusted bidirectionally.

In some embodiments of the present application, the abutment surface 4202 is provided with a groove at a position corresponding to the abutment 4210a, the abutment 4210a being received in the groove, the groove having a space for movement of the abutment 4210a in a direction of the corresponding sliding bearing shoe 2 to the bearing housing 1.

As shown in fig. 3, a groove 4202a is formed on the right end of the connecting portion 4201 and the abutting surface 4202, the abutting portion 4210a is located in the groove, a vertical gap is formed between the abutting portion 4210a and the connecting portion 4201, that is, a vertical gap is formed between the adjusting member 420 and the adjusting screw 4210, and the adjusting member 420 and the adjusting screw 4210 can move relatively in the vertical direction.

After the groove 4202a is formed on the adjusting member 420, the adjusting screw 4210 may be first positioned in the groove 4202a and then the limiting member 423 may be mounted on the adjusting member 420 when the adjusting screw 4210 is connected to the adjusting member 420, so that the adjusting screw 4210 and the adjusting member 420 may be more easily assembled.

Because the adjusting piece 420 and the fixing structure 41 are matched through the inclined plane, after the adjusting screw 4210 drives the adjusting piece 420 to horizontally move rightwards, a gap in the vertical direction is generated between the adjusting piece 420 and the fixing structure 41; because the adjusting piece 420 and the adjusting screw 4210 have a gap in the vertical direction, the adjusting piece 420 can move upwards relative to the adjusting screw 4210, so that a gap is generated between the adjusting piece 420 and the sliding bearing bush 2, and a space for the sliding bearing bush 2 to move upwards is reserved; when the rotating shaft 3 moves upwards due to the load, the rotating shaft 3 can push the sliding bearing bush 2 to move upwards, and abrasion caused by interference fit between the sliding bearing bush 2 and the rotating shaft 3 is avoided. It is understood that the size of the gap can be adjusted according to practical situations, and is not limited herein.

In addition, since a gap is provided between the connecting portion 4201 on the adjusting member 420 and the abutting portion 4210a of the adjusting screw 4210, the adjusting member 420 has a space moving downward, when the adjusting screw 4210 drives the adjusting member 420 to slide leftward, the fixing structure 41 can push the adjusting member 420 to move downward through the inclined surface 410, and the adjusting mechanism 4 is prevented from being locked.

In some embodiments of the present application, the limiting member 423 is connected to the adjusting member 420 and covers the groove, a limiting member through hole 423a is formed in the limiting member 423, the screw rod passes through the limiting member through hole 423a, and the limiting member through hole 423a has a space for the abutting portion 4210a to move in the direction from the corresponding sliding bearing shoe 2 to the bearing seat 1.

As shown in fig. 3, the limiting member is connected to the adjusting member 420, and the limiting member covers the groove, that is, the limiting member is disposed on both the upper portion and the lower portion of the adjusting screw 4210, so that the adjusting screw 4210 and the adjusting member 420 can be better connected. The limiting piece 423 is provided with a limiting piece through hole 423a through which the adjusting screw 4210 can pass, and a gap is formed between the adjusting screw 4210 and the limiting piece through hole 423a, so that the adjusting piece 420 and the limiting piece 423 can move upwards relative to the adjusting screw 4210; after the adjusting screw 4210 drives the adjusting piece 420 to horizontally move rightwards, the adjusting piece 420 can move upwards relative to the adjusting screw 4210, so that a gap is generated between the adjusting piece 420 and the sliding bearing bush 2, and a space for the sliding bearing bush 2 to move upwards is reserved; when the rotating shaft 3 moves upwards due to the load, the rotating shaft 3 can push the sliding bearing bush 2 to move upwards, and abrasion caused by interference fit between the sliding bearing bush 2 and the rotating shaft 3 is avoided. It is understood that the size of the gap can be adjusted according to practical situations, and is not limited herein.

It should be noted that, the limiting member 423 may be fixedly connected with the adjusting member 420, or may be detachably connected, in some embodiments of the present application, the limiting member 423 is a nut, and is connected to the connecting portion 4201 through a threaded sleeve, and the structure of the limiting member 423 is simple, and is detachable from the adjusting member 420, so that the adjusting member 420 is conveniently replaced when needed.

In some embodiments of the present application, the coupling member 4211 includes a fixing portion 4211a coupled to the bearing housing 1, and a position-limiting portion 4211b extending from the fixing portion 4211a toward the adjusting member 420, the adjusting screw 4210 is threadedly coupled to the fixing portion 4211a, and the coupling portion 4201 is located between the position-limiting portion 4211b and the bearing housing 1.

As shown in fig. 3, the fixing portion 4211a is connected with the bearing seat 1 by bolts to facilitate installation and replacement of the adjusting assembly 42, and it should be noted that the fixing portion 4211a and the bearing seat 1 may also adopt other connection methods according to actual conditions, such as welding, and the present invention is not limited thereto. The adjusting screw 4210 is in threaded connection with the fixing portion 4211a, the fixing portion 4211a extends towards the adjusting piece 420 to form a limiting portion 4211b, a space is formed between the limiting portion 4211b and the bearing seat 1, and the adjusting piece 420 and the adjusting screw 4210 are located in the space.

When the adjustment screw 4210 is rotated to move horizontally leftward, the adjustment screw 4210 abuts against the adjustment member 420 to move horizontally leftward, and the sliding of the inclined surface 410 on the fixed structure 41 abuts against the lower adjustment member 420 to move downward. It can be understood that there is a gap in the vertical direction between the limiting portion 4211b and the adjusting member 420, that is, a space for allowing the adjusting member 420 to move downward is required. Since the adjusting screw 4210 can only move horizontally, when the downward movement of the adjusting member 420 exceeds the gap between the adjusting member 420 and the adjusting screw 4210 in the vertical direction, the adjusting member 420 applies a force in the radial direction to the adjusting screw 4210; therefore, after the adjusting piece 420 moves downwards for a certain distance, the limiting portion 4211b can limit the adjusting piece to continue to move downwards, so that the phenomenon that the adjusting screw 4210 is subjected to overlarge force due to overlarge downward displacement of the adjusting piece 420 when the adjusting screw 4210 continues to rotate is avoided, and the risk that the adjusting screw 4210 is broken due to the fact that the adjusting screw 4210 is subjected to large radial force is reduced.

In some embodiments of the present application, the fixing structure 41 includes a supporting portion 412 and a positioning portion 411, the inclined plane 410 is disposed on the supporting portion 412, and a side of the supporting portion 412 facing away from the inclined plane 410 abuts against the bearing seat 1;

the positioning part 411 includes a first sub-positioning part 411a and a second sub-positioning part 411b, and the first sub-positioning part 411a and the second sub-positioning part 411b are distributed on both sides of the supporting part 412 in the sliding direction of the adjusting piece 420 to restrict the supporting part 412 from sliding in the sliding direction of the adjusting part.

As shown in fig. 3, the lower surface of the support part 412 is a slope 410, and the upper surface of the support part 412 abuts against the bearing housing 1. The first sub-positioning portion 411a and the second sub-positioning portion 411b of the positioning portion 411 are distributed on two sides of the supporting portion 412 to limit the supporting portion 412 to move leftwards or rightwards, so that the supporting portion 412 is prevented from being driven to move when the adjusting piece 420 horizontally slides, and the normal adjustment of the adjusting mechanism 4 is ensured. The second sub-positioning portion 411b is connected to the bearing housing 1, and the second sub-positioning portion 411b can be connected to the bearing housing 1 through a bolt, which facilitates installation and disassembly.

Since sliding friction is generated between the inclined surface 410 of the support part 412 and the adjustment when the adjustment of the slide bearing shoe 2 is performed, the surface of the support part 412 may be worn after the adjustment mechanism 4 is used for a long time. By providing the support part 412 which can be separated from the bearing housing 1, the support part 412 can be easily replaced when worn.

In some embodiments of the present application, the first sub-positioning portion 411a is disposed on the position-limiting portion 4211b, an avoiding groove 4110 is formed on a surface of the second sub-positioning portion 411b opposite to the first sub-positioning portion 411a, and one end of the adjusting member 420, which is far away from the adjusting screw 4210, is inserted into the avoiding groove 4110.

As shown in fig. 3, the first sub-positioning portion 411a is connected to the position-limiting portion 4211b, that is, the first sub-positioning portion 411a is connected to the connecting member 4211 in the driving structure 421, and the first sub-positioning portion 411a may be a side plate of the driving structure 421. Compared with the way of providing the first sub-positioning portion 411a on the bearing seat 1, when the first sub-positioning portion 411a is provided on the connection member 4211, the first sub-positioning portion 411a can be installed on the adjustment assembly 42 first, and then the adjustment assembly 42 is installed on the bearing seat 1, which is easier to implement in terms of process.

An avoiding groove 4110 is formed in the right side surface of the second sub-positioning portion 411b, and the left end of the adjusting member 420 is located in the avoiding groove 4110. It should be noted that, the avoiding groove 4110 has a gap that allows the adjusting member 420 to move horizontally and vertically, and the size of the gap affects the range in which the adjusting member 420 can move, i.e. the size of the gap is related to the adjusting range of the adjusting assembly 42; the size of the gap can be determined according to the actual situation, and is not limited herein.

It can be understood that, the avoiding groove 4110 can limit the displacement of the adjusting member 420, control the adjusting range of the adjusting assembly 42 within a set range, and meanwhile avoid generating a large radial force on the adjusting screw 4210 when the adjusting member 420 is displaced in the vertical direction greatly, thereby reducing the risk of breakage of the adjusting screw 4210.

In some embodiments of the present application, the plurality of sliding bearing shoes 2 includes a guide shoe 21, the guide shoe 21 is disposed on the inner surface 101 of the mounting hole 10, and the adjustment mechanism 4 is disposed between the guide shoe 21 and the inner surface 101 of the mounting hole 10; in the axial direction of the rotating shaft 3, the inclined surface 410 is inclined in the direction from the guide shoe 21 to the bearing housing 1; and/or the sliding bearing pads 2 comprise thrust pads, the thrust pads are arranged on the end surface 12 of the bearing seat 1 along the axial direction of the mounting hole 10, and an adjusting mechanism 4 is arranged between the thrust pads and the end surface 12; in the radial direction of the mounting hole 10, the inclined surface 410 is inclined in the direction of the thrust shoe to the end face 12.

Referring to fig. 1, 2 and 3, the sliding bearing shoe 2 is a guide shoe 21, and the guide shoe 21 is connected to the inner surface 101 of the bearing seat 1 and disposed around the rotating shaft 3 to radially support the rotating shaft 3. The adjustment mechanism 4 is provided between the guide shoe 21 and the inner surface 101, and the inner surface 101 abuts against the support portion 412. The inclined surface 410 of the supporting portion 412 is inclined upward or downward, and it is understood that when the inclined surface 410 is inclined upward, pushing the adjusting member 420 leftward moves the guide shoe 21 downward, and when the inclined surface 410 is inclined downward, pulling the adjusting member 420 rightward moves the guide shoe 21 downward, i.e., the inclined direction of the inclined surface 410 affects the adjustment manner of the adjustment assembly 42.

It should be noted that the difference in the slope of the slope 410 affects the adjustment accuracy of the adjustment mechanism 4. The greater the slope of the inclined surface 410, the greater the distance the guide shoe 21 moves in the radial direction of the rotary shaft 3 when the distance the adjustment assembly 42 moves in the axial direction of the rotary shaft 3 is the same, the higher the sensitivity of the adjustment assembly 42, but the accuracy of the adjustment is reduced because the position of the guide shoe 21 in the radial direction of the rotary shaft 3 varies greatly, i.e., the guide shoe 21 cannot move a small distance in the radial direction of the rotary shaft 3. In addition, the greater the slope of the ramp 410, the greater the installation space required for the adjustment assembly 42.

In summary, the inclination direction and the inclination of the inclined plane 410 need to be determined according to actual situations, and are not limited herein.

With reference to fig. 1, 2 and 4, the sliding bearing shoe 2 is a thrust shoe 22, the thrust shoe 22 is connected to the end surface 12 of the bearing seat 1 along the axial direction of the mounting hole 10 to support the rotating shaft 3 in the axial direction of the rotating shaft 3, and the surface of the left side of the bearing seat 1 connected to the adjusting mechanism 4 is the end surface 12. The adjusting mechanism 4 is disposed between the thrust pad 22 and the bearing housing 1 to adjust a gap between the thrust pad 22 and the rotating shaft 3. As shown in fig. 4, when the adjusting member 420 is pushed to move downward, the inclined surface 410 on the supporting portion 412 pushes the adjusting member 420 to move leftward, and the adjusting member 420 pushes the thrust shoe 22 to move leftward, so as to reduce the gap between the thrust shoe 22 and the rotating shaft 3. It is understood that the inclination direction and the slope of the inclined surface 410 at the thrust shoe 22 also affect the adjustment of the thrust shoe 22, and will not be described in detail herein.

With reference to fig. 1, 2, and 4, in the adjusting mechanism 4 at the thrust pad 22, an adjusting end of the adjusting screw 4210 is located at an end of the adjusting screw 4210, which is away from a central line of the rotating shaft along a radial direction of the rotating shaft, so that a worker can conveniently rotate the adjusting screw 4210 to adjust the adjusting mechanism 4.

It should be noted that, on the premise of comprehensively considering factors such as cost and process, the adjusting mechanism 4 may be disposed at the sliding bearing shoe 2 that needs to be adjusted according to actual conditions.
