Fig. 3 is a cross-sectional view of a rotating shaft supporting structure according to an embodiment of the present invention, and as shown in fig. 3, the rotating shaft supporting structure 132 includes a mounting seat 1321, an elastic component 1322 and a bearing shoe 1323, wherein the mounting seat 1321 is configured to be mounted on the bearing seat 131 to ensure that the rotating shaft supporting structure 132 is stable relative to the bearing seat 131. The mounting seat 1321 includes a supporting plate 1321a and a limiting portion 1321b, the supporting plate 1321a is used for supporting and placing the elastic component 1322, so as to facilitate the distribution and installation of the elastic component 1322, and is connected with the bearing seat 131, the supporting plate 1321a has a supporting surface (not shown), the limiting portion 1321b is disposed on the supporting surface, and the supporting surface and the limiting portion 1321b are matched together to limit the moving position of the elastic component 1322, so as to prevent the elastic component 1322 from deviating too much or separating from the supporting plate 1321a to cause the failure of the whole rotating shaft supporting structure 132.

Optionally, the elastic component 1322 may include a plurality of elastic members 1322a, the elastic component 1322 is connected to the bearing shoe 1323, during use, the plurality of elastic members 1322a jointly bear a pressure applied by the bearing shoe 1323, the installation number of the elastic members 1322a and the structural composition and distribution of the elastic members 1322a can be adjusted by applying the pressure to the bearing shoe 1323 and calculating the bearing capacity of a single elastic member 1322a, under the condition that the bearing capacity and rigidity of the elastic member 1322a meet requirements are ensured, the overall thickness of the elastic member 1322a can be reduced as much as possible, the space occupancy rate is reduced, the manufacturing cost of the rotating shaft support structure 132 can be reduced, and the processing of the entire bearing device 130 is facilitated.

Optionally, a plurality of elastic pieces 1322a are detachably mounted on the supporting plate 1321a, and when a certain elastic piece 1322a fails, the elastic piece 1322a can be purposefully replaced without completely replacing the whole elastic piece 1322, so that the mounting efficiency and the use convenience of the elastic piece 1322 are greatly improved, and certain processing cost is saved.

It should be noted that, in the embodiment of the present application, the overall thickness of the elastic component 1322a is 50mm, and may be adjusted according to design requirements, and the elastic component 1322a should meet the requirement of the tilting distance of the bearing tile 1323 besides the requirement of the load-bearing capacity and the rigidity, that is, the elastic component 1322a should have a certain compressible or stretchable distance, so that the tilting of the bearing tile 1323 can be sufficiently alleviated, and the elastic component 1322a can be prevented from being in a state of a compression or stretching limit for a long time, thereby prolonging the service life of the elastic component 1322 a.

Optionally, one end of the elastic piece 1322a may be provided with an abutting portion 1322b, the abutting portion 1322b abuts against the supporting surface of the supporting plate 1321a, and a portion of the abutting portion 1322b of at least one of the elastic pieces 1322a is located between the supporting surface and the limiting portion 1321b, so that the elastic piece 1322a may be compressed up and down along with the inclination of the bearing tile 1323 through the mutual fit between the supporting surface and the limiting portion 1321b, and is not separated from the supporting plate 1321a or directly slides off from the mounting seat 1321, thereby ensuring the stability of the rotating shaft supporting structure 132.

The cross-sectional area of the abutting portion 1322b should be larger than that of the rest of the elastic member 1322a, so that when a part of the abutting portion 1322b is located between the supporting surface and the limiting portion 1321b, the rest of the elastic member 1322a is not limited by the limiting portion 1321b, so that when the bearing block 1323 tilts, the limiting portion 1321b can prevent the bearing block 1323 from compressing the elastic member 1322 a. In addition, the cross section of the abutting portion 1322b may be circular, square, trapezoidal or other desired shapes, and the shape thereof may be designed to match the structure of the limiting portion 1321b, so long as a part of the abutting portion 1322b is located between the supporting surface and the limiting portion 1321 b.

It should be noted that, the bearing tile 1323 is connected to one end of the elastic member 1322a away from the abutting portion 1322b, when the bearing tile 1323 is tilted, the corresponding position of the elastic member 1322a is compressed or stretched to alleviate the adverse effect caused by the tilting of the bearing tile 1323, because a part of the abutting portion 1322b of the elastic member 1322a is located between the limiting portion 1321b and the supporting surface, the elastic member 1322a is not separated from the supporting plate 1321a when the elastic member 1322a is stretched, after the bearing tile 1323 returns to the normal position, the elastic member 1322a returns to the initial state until the elastic member 1322a fails or is damaged due to the long-time reciprocating motion, and at this time, only the failed elastic member 1322a needs to be replaced.

Optionally, a supporting surface of the supporting plate 1321a may be provided with a groove 1321c for placing the elastic member 1322a, and the abutting portion 1322b of the plurality of elastic members 1322a abuts against a bottom surface of the groove 1321c, and the circumferential movement of the elastic member 1322a may be limited by the arrangement of the groove 1321c, so that the elastic member 1322a may only move within the range of the groove 1321 c; at this time, the limiting portion 1321b is protruded at the side surface of the groove 1321c, and a part of the abutting portion 1322b of the elastic member 1322a close to the side surface of the groove 1321c is located between the limiting portion 1321b and the bottom surface of the groove 1321c, so that when the bearing tile 1323 obliquely extrudes the elastic member 1322a, the elastic member 1322a which is not extruded is moved out of the groove 1321c due to the tensile force, and cannot be returned to the groove 1321c again when the bearing tile 1323 returns to the normal position, thereby causing the failure of the rotating shaft supporting structure 132, and even causing the abnormal operation of the rotating shaft and the bearing tile 1323.

The limiting portions 1321b protruding from the side surface of the groove 1321c may be symmetrically distributed on two sides of the side surface of the groove 1321c according to design requirements, or symmetrically distributed around the side surface of the groove 1321c, and only the elastic member 1322a needs to be ensured not to slide out of the groove 1321c when the bearing tile 1323 is inclined.

Optionally, the limiting portion 1321b protruding from the side surface of the groove 1321c may further extend along the circumferential direction of the groove 1321c, wherein a portion of the abutting portion 1322b of the elastic member 1322a close to the side surface of the groove 1321c is located between the bottom surface of the groove 1321c and the limiting portion 1321b, so that the periphery of the elastic member 1322 is limited by the limiting portion 1321b protruding from the side surface of the groove 1321c, thereby ensuring that the elastic member 1322a cannot be disengaged from the groove 1321c no matter the bearing block 1323 is inclined in any direction.

It should be noted that, because the bearing pad 1323 is directly connected to the end of the elastic member 1322a away from the abutting portion 1322b, there is a certain restriction relationship between the opening size and depth of the groove 1321c and the height of the elastic member 1322a, when the height of the elastic member 1322a is smaller than the depth of the groove 1321c, a part of the end of the bearing pad 1323 connected to the elastic member 1322a is also located in the groove 1321c, and because the bearing pad 1323 is inclined, the area of the groove 1321c needs to meet the requirement that the inclination of the bearing pad 1323 in the groove 1321c is not blocked by the side surface of the groove 1321c, that is, the opening size of the groove 1321c cannot be smaller than the inclination range of the bearing pad 1323; when the height of the elastic piece 1322a is greater than the depth of the groove 1321c, one end of the elastic piece 1322a, which is far away from the abutting portion 1322b, is located outside the groove 1321c, if the height of the elastic piece 1322a is smaller than the depth of the groove 1321c in the compression process of the bearing tile 1323, the opening size of the groove 1321c still needs to meet the inclination range of the bearing tile 1323, and if the elastic piece 1322a is located outside the groove 1321c all the time in the compression process of the bearing tile 1323, the opening size of the groove 1321c only needs to be ensured to be capable of placing all the elastic pieces 1322 a.

Optionally, in the actual machining process, in the case that a part of the abutting portion 1322b of the elastic member 1322a is located between the limiting portion 1321b and the bottom surface of the groove 1321c, the depth of the groove 1321c may be selected to be as small as possible, that is, in the compressible range in which the elastic member 1322a tilts along with the bearing tile 1323, one end of the elastic member 1322a away from the abutting portion 1322b is always located outside the groove 1321c, so that the risk that the end is blocked by the side surface of the groove 1321c when the bearing tile 1323 tilts is reduced as much as possible.

Optionally, the slot 1321c may be formed with a mounting opening (not shown) at a side of the supporting plate 1321a, the mounting opening facilitates the mounting of the elastic component 1322 to the mounting seat 1321, as shown in fig. 4, the mounting seat 1321 further includes a blocking plate 1321d, and the blocking plate 1321d is detachably connected to the supporting plate 1321a and blocks the mounting opening. When the elastic member 1322a is coupled to the bearing block 1323, the supporting plate 1321a slides along the mounting opening from the side of the elastic member 1322 to confine the elastic member 1322 in the recess 1321c, and then the blocking plate 1321d is coupled to the supporting plate 1321a to block the mounting opening, thereby preventing the elastic member 1322a from being separated from the supporting plate 1321 a.

Optionally, the baffle 1321d may be connected to the supporting plate 1321a through a third connecting member 1321e, a fifth fixing hole penetrating through the baffle 1321d is formed in the baffle 1321d, and a sixth fixing hole is formed in a surface of the supporting plate 1321a connected to the baffle 1321 d. In the embodiment of the present application, the third connecting element 1321e may be a screw, and the fifth fixing hole and the sixth fixing hole are respectively provided with a thread, and when the fixing device is installed, the screw passes through the fifth fixing hole and is screwed into the sixth fixing hole along the thread direction; when the elastic member 1322a needs to be replaced, the elastic member 1322a can be replaced only by screwing the screw out of the sixth fixing hole in the opposite direction and then removing the baffle 1321d and the support plate 1321a, and the whole process is simple and convenient.

The mounting opening may be formed only on one side of the support plate 1321a, or may be formed on both sides of the support plate 1321 a; when the mounting openings are formed on the two opposite sides of the supporting plate 1321a, the mounting openings on the two sides can be covered by the baffle 1321d, or only one side can be covered by the baffle 1321d, and the other side is directly limited by the bearing seat 131, so that the elastic member 1322a is only limited in the structural range of the groove 1321c and can move without departing from the supporting plate 1321 a.

Optionally, only one limiting portion 1321b may be disposed on the supporting surface, for example, the limiting portion 1321b is located between the elastic members 1322a, the limiting portion 1321b includes a first sub-limiting portion perpendicular to the supporting surface and a second sub-limiting portion extending to both sides along the first sub-limiting portion, wherein a portion of the abutting portion 1322b of the elastic member 1322a close to the first sub-limiting portion is located between the supporting surface and the second sub-limiting portion, that is, the limiting portion 1321b simultaneously performs position limitation on two or more elastic members 1322a located around the first sub-limiting portion, and the first sub-limiting portion itself also plays a role in preventing the elastic members a from performing circumferential movement, thereby ensuring stability of the entire rotating shaft supporting structure 1322 132.

Optionally, a plurality of limiting portions 1321b may be simultaneously disposed on the supporting surface, each limiting portion is located on one side of the abutting portion of the at least one elastic member, which is away from the supporting surface, and the plurality of limiting portions 1321b may be distributed around the supporting surface, at this time, the second sub-limiting portion extends only along the first sub-limiting portion to one side close to the elastic member 1322a, and is used for performing position limitation on the elastic member 1322a at the corresponding position on the outermost side of the elastic member 1322; in addition, the plurality of limiting portions 1321b may also be uniformly distributed on the whole supporting surface, and a part of the abutting portion 1322b of the elastic piece 1322a close to the limiting portion 1321b is located between the limiting portion 1321b and the supporting surface, and the stability of the whole rotating shaft supporting structure 132 can be further enhanced by the matching use of the plurality of limiting portions 1321 b.

It should be noted that the limiting portion 1321b may be designed to have different shapes according to the structural requirement of the elastic member 1322a, for example, the cross section of the limiting portion 1321b may be a circle, a square, a trapezoid, or other required shapes; in addition, the angle formed between the limiting portion 1321b and the supporting surface can also be adjusted according to the structural requirements of the elastic piece 1322a, for example, when the limiting portion 1321b is in a cylindrical rod shape or the contact surface between the abutting portion 1322b of the elastic piece 1322a and the limiting portion 1321b is trapezoidal, the angle between the limiting portion 1321b and the supporting surface can be smaller than 90 °, and at this time, a part of the abutting portion 1322b of the elastic piece 1322a at the corresponding position is located in the included angle area formed by the limiting portion 1321b and the supporting surface and abuts against the supporting surface and the side surface of the limiting portion 1321b at the same time, so that the limit of the movement position of the elastic piece 1322a is realized.

Optionally, the bearing tile 1323 has a mounting surface opposite to the mounting seat 1321, and is configured to be connected with the elastic piece 1322a, the mounting surface is provided with a first fixing hole 1323a, the elastic piece 1322a is provided with a second fixing hole 1322c penetrating through the mounting surface, and the first fixing holes 1323a correspond to the second fixing holes 1322c one to one; also included in the shaft support structure 132 is a first connector 1324, and the first connector 1324 passes through the second fixing hole 1322c and is inserted into the first fixing hole 1323a to connect the bearing block 1323 and the elastic member 1322a together.

Alternatively, the first connecting member 1324 used in the rotating shaft supporting structure 132 in the embodiment of the present application may be a screw, and the first fixing hole 1323a and the second fixing hole 1322c may be respectively provided with threads, so that when the bearing tile 1323 and the elastic member 1322a are connected, the screw is inserted through the second fixing hole 1322c, and is screwed into the first fixing hole 1323a along the direction of the threads; when one elastic piece 1322a fails and is damaged, the elastic piece 1322a can be detached by directly screwing the screw out of the first fixing hole 1323a in the opposite direction, and the whole installation and detachment process is simple and convenient.

It should be noted that, when the bearing block 1323 and the elastic member 1322a are connected by using a screw, the screw should be completely screwed into the second fixing hole 1322c, and a certain gap is left between the screw and the surface of the supporting plate 1321a, on one hand, the distribution of the elastic member 1322a on the supporting plate 1321a can be prevented from being disturbed, so that the stability of the rotating shaft supporting structure 132 is affected; on the other hand, if the screw is not completely screwed into the second fixing hole 1322c, or is just flush with the bottom surface of the abutting portion 1322b of the elastic member 1322a, i.e. the screw abuts against the supporting plate 1321a simultaneously with the elastic member 1322a, when the bearing tile 1323 is tilted, since the contact surface between the elastic member 1322a and the supporting plate 1321a is also the contact surface between the screw and the supporting plate 1321a, the elastic member 1322a is not compressible, and the bearing tile 1323 cannot be adjusted by pressing the elastic member 1322a, thereby causing the failure of the rotating shaft supporting structure 132.

Optionally, when the plurality of elastic members 1322a are distributed, in order to ensure that all areas of the bearing block 1323 and the elastic component 1322 are uniformly stressed, the plurality of elastic members 1322a may be uniformly distributed on the supporting plate 1321a, so that it is possible to prevent a certain elastic member 1322a from being compressed or stretched excessively due to an excessively large stress, thereby causing failure of the elastic member 1322a and reducing the stability of the entire rotating shaft supporting structure 132; meanwhile, the uniform distribution of the elastic pieces 1322a also makes the structure and distribution of the limiting portion 1321b on the supporting plate 1321a simpler, and greatly simplifies the processing technique of the rotating shaft supporting structure 132.

It should be noted that, a plurality of elastic members 1322a may be selected to be closely distributed on the supporting plate 1321a, as shown in fig. 4, that is, the side edges of the plurality of elastic members 1322a abut against each other, when this arrangement method is adopted, the overall structure of the elastic member 1322 is most stable, at this time, because the number of elastic members 1322a at the lower end of each bearing tile 1323 is large, the pressure applied to a single elastic member 1322a is reduced, so that the requirement for the load bearing capacity of the single elastic member 1322a is reduced, and the structural design of the single elastic member 1322a is simpler. A plurality of resilient members 1322a may also be distributed uniformly over support plate 1321a, and the corresponding load carrying capacity and stiffness requirements for a single resilient member 1322a may be increased due to the reduced number of resilient members 1322 a. In the actual application process, the distribution of the elastic members 1322a may be designed according to actual requirements, and meanwhile, an appropriate type of the elastic members 1322a is selected for installation, so as to ensure the stability of the rotating shaft supporting structure 132.

Optionally, the elastic member 1322a used in the embodiment of the present application may be selected as a disc spring, and compared with a common spring, the disc spring can bear a very large load in a small space, and the deformation energy per unit volume of the disc spring is large, and has a good buffering and shock absorbing capability, and particularly when the disc spring is stacked and combined, the effect of absorbing impact and dissipating energy of the disc spring is more significant due to the friction resistance effect of the surface. The disc spring has variable rigidity characteristic, different disc spring characteristic curves can be obtained by changing the ratio of the height of the truncated cone in the disc to the thickness of the disc, and in addition, the variable rigidity characteristic of the disc spring can be obtained by combining the discs with different thicknesses or by different combination modes of overlapping the discs with different numbers.

In the embodiment of the application, the shape, thickness and number of the discs of the disc spring can be adjusted according to design requirements, so as to meet the requirements of bearing capacity and rigidity of the disc spring. The disc spring is generally ring-shaped and has a through hole structure in the middle, and when the disc spring is coupled to the bearing block 1323, the first coupling member 1324 may pass through the disc spring and be inserted into the first fixing hole 1323a on the surface of the bearing block 1323, so as to couple the disc spring and the bearing block 1323 together.

Optionally, the initial thickness of the elastic piece 1322a may be adjusted according to design requirements, that is, the overall thickness of the disc spring formed by the disc may also be adjusted, because the disc spring may bear a great load in a small space, and the deformation energy per unit volume is large, the overall thickness of the disc spring may be as small as possible under the condition of meeting performance requirements, so as to reduce the space occupation, thereby reducing the volume of the whole bearing.

It should be noted that the elastic member 1322a used in the embodiment of the present application may also be another type of spring or other compressible elastic material, and only a certain load-bearing capacity and rigidity of the elastic member 1322a within the designed thickness range need to be ensured, that is, when the bearing block 1323 tilts along with the rotating shaft 133, the elastic member 1322a should be able to bear the stress applied when the bearing block 1323 tilts, and can deform along with the tilting of the bearing block 1323, so as to prevent the rotating shaft 133 from scratching the bearing block 1323.

Optionally, the second connecting element 1324 used in this embodiment of the application may also be a screw, and the third fixing hole and the fourth fixing hole may be correspondingly provided with threads, so that when the mounting seat 1321 and the bearing seat 131 are connected, the screw passes through the third fixing hole, and is screwed into the fourth fixing hole in a rotating manner along a direction of the threads; in the long-time use, because the slope of bearing tile 1323 leads to frequent interact between mount pad 1321 and elastic component 1322a for when mount pad 1321 damaged, can directly unscrew the screw from the fourth fixed orifices along opposite direction, can pull down mount pad 1321, whole installation dismantlement process is simple and convenient.

It should be noted that when the mounting seat 1321 and the bearing seat 131 are fixed by using the screw, the screw should be completely screwed into the third fixing hole so as not to interfere with the distribution of the elastic member 1322a on the supporting plate 1321a, thereby affecting the stability of the rotating shaft supporting structure 132.
