Description

Technical Field

[0001] This utility model relates to the field of bearings, and in particular to an integrally connected pressure bearing and a rotating load-bearing structure. Background Technology

[0002] With the booming development of the automation industry, automated equipment is widely used in various fields such as industrial manufacturing, logistics warehousing, and intelligent services. The demand for automated products in terms of motion control, precise positioning, and efficient transmission is becoming increasingly diversified and sophisticated. As a key basic component that enables flexible joint movement and ensures stable equipment operation, the performance, structure, and adaptability of bearings directly affect the overall operating efficiency of automated equipment.

[0003] Currently, most standard pressure bearings on the market adopt a separate base and cover plate design. In practical applications, when these pressure bearings need to be connected and fixed to other equipment, due to the limitations of their separate structure, it is often necessary to design and install special adapters to achieve a stable and reliable connection between the bearing and the equipment. This process not only increases the complexity of equipment assembly and prolongs installation and commissioning time, but also requires users to invest more manpower in the design, processing, and installation of adapters, significantly increasing labor and time costs. In addition, the introduction of additional adapters may also affect the overall stability and reliability of equipment operation due to assembly errors and the precision of fit between components, making it difficult to meet the automation industry's application requirements for efficiency, convenience, and precision, and failing to provide users with a good operating experience and application results. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide an integrated pressure bearing and a rotating bearing structure, which solves the problems of the separate structure design of the bearing base and the cover plate in the prior art and the need for additional adapters to connect the equipment.

[0005] To solve the above-mentioned technical problems, this utility model provides an integrated pressure bearing and a rotating load-bearing structure, including:

[0006] A load-bearing structural component, comprising a base and a cover plate; a shaft is provided on the side of the base facing the cover plate, a shaft adapter hole is provided in the center of the cover plate, the cover plate covers the base, the shaft is sleeved in the shaft adapter hole, and a friction cavity is provided between the cover plate and the base.

[0007] Several rolling elements are embedded in the friction cavity, and the rolling elements respectively abut against the base and the cover plate; when the base and the cover plate rotate relative to each other, the rolling elements reduce rotational friction and bear load by rolling themselves.

[0008] As a more preferred embodiment, a pressure plate is provided on the other side of the cover plate. The pressure plate is fixedly connected to the shaft passing through the cover plate and is used to limit the relative position of the shaft and the cover plate axially. The advantage is that by providing a pressure plate fixedly connected to the shaft on the other side of the cover plate to limit the relative position of the shaft and the cover plate axially, the pressure plate, the cover plate, and the base form a stable integrated connection structure. The pressure plate axially limits the shaft and the cover plate, preventing them from moving around during relative rotation, and further enhancing the stability of the overall structure of the pressure bearing.

[0009] As a more preferred method, the pressure plate is annular, with its inner diameter being the same as the inner diameter of the shaft. Several limiting holes are provided on the outer side of the inner ring of the pressure plate. The advantages are that the annular pressure plate design allows for better fit with the shaft and cover plate, and the fact that its inner diameter is the same as the inner diameter of the shaft allows the pressure plate to be precisely fitted onto the shaft, forming an integrated structure with the cover plate and base. Through the limiting holes on the outer side of the inner ring of the pressure plate, it can be connected and fixed to the cover plate and base at multiple points, enhancing the stability of the overall structure and simplifying the connection structure and assembly process.

[0010] As a more preferred approach, the outer surface of the shaft end is provided with a plurality of fixing holes, the fixing holes corresponding one-to-one with the limiting holes; the advantage of this is that the fixing holes on the outer surface of the shaft end correspond one-to-one with the limiting holes of the pressure plate, so that the shaft, pressure plate and cover plate can be directly fixedly connected by fasteners. This design further optimizes the integrated structure of the bearing and reduces the assembly complexity; the precise correspondence of the hole positions ensures a tight fit between the shaft, pressure plate and cover plate, and improves the stability of the overall structure.

[0011] As a more preferred embodiment, a fastener is provided on one outer surface of the pressure plate; the fastener passes through a limiting hole on the pressure plate and is fixedly connected to a corresponding fixing hole on the shaft, thus confining the cover plate between the pressure plate and the shaft. The advantage is that the fastener on one outer surface of the pressure plate passes through the limiting hole of the cover plate and is fixedly connected to the fixing hole of the shaft, confining the cover plate between the pressure plate and the shaft, making the cover plate, base, and pressure plate form an integrated structure; the connection method of the fastener creates a rigid constraint between the pressure plate and the shaft, and also firmly axially confines the cover plate, effectively preventing relative displacement between components, allowing the pressure bearing to reliably transmit loads.

[0012] As a more preferred embodiment, the outer surface of the cover plate facing the pressure plate is provided with an annular groove along the outer edge of the shaft adapter hole. The outer diameter of the annular groove is not less than the outer diameter of the pressure plate, and the pressure plate is embedded in the annular groove. The advantages are that the annular groove on the cover plate facing the pressure plate, through its inner diameter adapting to the shaft and its outer diameter accommodating the pressure plate, allows the pressure plate to be precisely embedded in the annular groove. This structural design further ensures the pressure plate fits snugly against the base, axially limiting the cover plate between the pressure plate and the base, forming a stable, integrated connection structure. The embedding of the annular groove and the pressure plate increases the contact area between components, resulting in uniform pressure distribution and effectively avoiding localized stress concentration. This embedding method provides dual circumferential and radial limiting for the pressure plate, ensuring that each component maintains a relatively fixed positional relationship when the cover plate and base rotate relative to each other. Furthermore, embedding the pressure plate in the annular groove of the cover plate also facilitates the connection and fixation of the cover plate and the pressure body it is connected to, enhancing the overall structural stability and reliability.

[0013] As a more preferred embodiment, a first outer ring protrusion is provided on the outer peripheral surface of the shaft body extending axially towards the cover plate, and a first groove is formed between the first outer ring protrusion and the shaft body; a second outer ring protrusion is provided on the outer peripheral surface of the shaft adapter hole extending axially towards the base, and a second groove is formed between the second outer ring protrusion and the shaft adapter hole; the friction cavity is formed by the first groove and the second groove. Its advantages are that the first groove of the shaft body and the second groove of the shaft adapter hole on the cover plate precisely abut against each other, directly forming a friction cavity. The friction cavity provides a precise running track for the rolling elements, ensuring uniform force distribution when the rolling elements bear loads, enhancing the overall bearing capacity and impact resistance of the bearing, and reducing the risk of equipment failure due to loose connections or structural instability.

[0014] As a more preferred approach, some of the rolling elements are spheres. The advantages are that the spheres, as rolling elements, can achieve point contact rolling with the contact surfaces of the base and cover plate within the friction cavity formed by the base and cover plate. The load-bearing capacity of the spheres is relatively balanced in all directions. This contact method allows the base and cover plate to be subjected to more uniform force during relative rotation. When the pressure bearing bears external loads, the spheres can evenly distribute the force to the base and cover plate, avoiding localized stress concentration that could lead to component damage. Compared to the uneven stress introduced by the transition parts in traditional separable bearings, this design further enhances the overall integrated connection stability of the bearing. When the spheres roll, compared to other rolling elements such as cylinders, their rolling friction coefficient is lower, allowing them to move within the friction cavity with minimal resistance, thus improving the bearing's rotational efficiency.

[0015] To address the aforementioned problems, this utility model also provides a rotating bearing structure, comprising: the aforementioned integrally connected pressure bearing; a support body and a pressure body, wherein the base is disposed on the top of the support body, and the cover plate is disposed on the bottom of the pressure body, and the base and the cover plate rotate relative to each other, thereby causing the support body and the pressure body to rotate relative to each other.

[0016] As a preferred embodiment, the base is provided with a first mounting hole for fixed connection with the support body; the cover plate is provided with a second mounting hole for fixed connection with the pressure body. The advantage lies in the fact that the base and cover plate can be directly fixedly connected to the support body and pressure body through the first and second mounting holes at the four corners of their outer perimeter walls, respectively. This design abandons the traditional connection mode of separate pressure bearings that relies on adapters. Through a standardized mounting hole layout, a stable integrated structure is formed between the bearing and the equipment. The mounting holes are located at the four corners of the outer perimeter walls of the base and cover plate, which can form a symmetrical and uniform force distribution during connection, avoiding local stress concentration. This layout can effectively prevent loosening or displacement between the bearing and the equipment, ensuring that the relative rotation of the base and cover plate can stably drive the operation of the support body and pressure body, thus enhancing the stability and reliability of the overall structure.

[0017] As described above, the integrated pressure bearing and rotating load-bearing structure of this utility model have the following beneficial effects: The integrated pressure bearing of this utility model forms a sleeve structure between the base and the cover plate through a shaft and a shaft adapter hole, changing the traditional structural design where the base and cover plate are separate. By setting a pressure plate fixedly connected to the shaft on the other side of the cover plate, the relative position of the shaft and the cover plate is defined axially, thus axially limiting the cover plate between the pressure plate and the base, forming a stable integrated structure. This integrated structure allows the base and cover plate to form a tightly fitted whole, enabling more stable and reliable load transmission and improving the stability and reliability of the pressure bearing during equipment operation.

[0018] This utility model's rotating bearing structure features an integrated pressure bearing whose base and cover plate are directly and fixedly connected to the support body and pressure body respectively through mounting holes on the base and cover plate. This eliminates the traditional method of connecting separate bearings using adapters, avoiding assembly gaps and loosening risks introduced by adapters, and ensuring the pressure bearing forms a stable whole with the equipment. During equipment operation, the relative rotation of the base and cover plate stably drives the support body and pressure body to rotate synchronously, ensuring more stable force transmission. The direct assembly of the bearing base to the support body and the cover plate to the pressure body simplifies the connection structure, reduces connection steps, lowers installation complexity, and significantly improves the efficiency of integrating the pressure bearing with the equipment.

[0019] This utility model discloses an integrated pressure bearing and a rotating load-bearing structure. By using a pressure plate to axially limit the cover plate between the pressure plate and the base, a stable integrated structure is formed, which solves the problem of the separate structure design of the bearing base and the cover plate in the prior art. Furthermore, by directly setting mounting holes on the base and cover plate of the integrated pressure bearing, the problem of the bearing requiring additional adapters to connect to the equipment in the prior art is solved.

[0049] like Figure 1 , Figure 2 As shown, this utility model provides an integrally connected pressure bearing, comprising:

[0050] The supporting structure 1 includes a base 11 and a cover plate 12; a shaft 111 is provided on the side of the base 11 facing the cover plate 12, and a shaft adapter hole 121 is provided in the center of the cover plate 12. The cover plate 12 covers the base 11, and the shaft 111 is sleeved in the shaft adapter hole 121. A friction cavity 13 is provided between the cover plate 12 and the base 11.

[0051] like Figure 3 As shown, a plurality of rolling elements 2 are embedded in the friction cavity 13, and the plurality of rolling elements 2 respectively abut against the base 11 and the cover plate 12; when the base 11 and the cover plate 12 rotate relative to each other, the rolling elements 2 reduce rotational friction and bear load by rolling themselves.

[0052] To better illustrate the integrated pressure bearing of this invention, the following specific application will be used as an example: The integrated pressure bearing of this invention forms a sleeve structure between the base 11 and the cover plate 12 through the shaft body 111 and the shaft adapter hole 121, changing the traditional structural design where the base 11 and cover plate 12 are separate. A pressure plate 3, fixedly connected to the shaft body 111, is provided on the other side of the cover plate 12 to axially limit the relative position of the shaft body 111 and the cover plate 12, thus axially limiting the cover plate 12 between the pressure plate 3 and the base 11, forming a stable integrated structure. This integrated structure allows the base 11 and cover plate 12 to form a tightly fitted whole, enabling more stable and reliable load transmission and improving the stability and reliability of the pressure bearing during equipment operation.

[0053] In some possible embodiments of this utility model, such as Figure 1As shown, a pressure plate 3 is provided on the other side of the cover plate 12. The pressure plate 3 is fixedly connected to the shaft 111 passing through the cover plate 12, and is used to limit the relative position of the shaft 111 and the cover plate 12 axially. It can be understood that the shaft 111 faces the cover plate, and the outer diameter of the shaft 111 is smaller than the diameter of the shaft adapter hole 121 on the cover plate 12, so as to satisfy the function of limiting the shaft 111 and the shaft adapter hole 121. After the end of the shaft 111 passes through the shaft adapter hole 121, it does not extend beyond the outer surface of the pressure plate side of the cover plate 12, facilitating the fixed connection between the pressure plate 3 and the shaft 111. By providing a pressure plate fixedly connected to the shaft on the other side of the cover plate to limit the relative position of the shaft and the cover plate axially, the pressure plate, cover plate, and base form a stable integrated connection structure; the pressure plate axially limits the shaft and the cover plate, preventing them from shifting during relative rotation.

[0054] In some possible embodiments of this utility model, such as Figure 1 As shown, the pressure plate 3 is annular, and its inner diameter is the same as that of the shaft 111. Several limiting holes 31 are provided on the outer side of the inner ring of the pressure plate 3. It can be understood that the shaft 111 is fitted into the shaft adapter hole 121 of the cover plate, and the pressure plate 3 presses against the shaft adapter hole 121 of the cover plate, abutting against the end of the shaft 111 within the shaft adapter hole 121, thus satisfying the positional requirements for the fixed connection between the pressure plate 3 and the shaft 111. Optionally, the several limiting holes 31 are through holes. In other embodiments, the several limiting holes 31 can also be sliding groove holes, etc., which are not limited here. Optionally, the number of limiting holes 31 is 4. In other embodiments, the number of limiting holes 31 can also be 3, 5, etc., which are not limited here, as long as they are evenly distributed at the end of the shaft 111. The design of the annular pressure plate 3 allows it to better fit with the shaft 111 and the cover plate 12. Its inner diameter is the same as that of the shaft, which allows the pressure plate 3 to be precisely connected to the shaft 111 and form an integrated structure with the cover plate 12 and the base 11. Through the limiting hole 31 on the outer side of the inner ring of the pressure plate 3, it can be connected and fixed to the cover plate 12 and the base 11 at multiple points, which enhances the stability of the overall structure and simplifies the connection structure and assembly process.

[0055] In some possible embodiments of this utility model, such as Figure 1As shown, the outer surface of the shaft 111 end is provided with a plurality of fixing holes 112, and the fixing holes 112 correspond one-to-one with the holes of the limiting holes 31. Understandably, the number and position distribution of the fixing holes 112 completely correspond to the limiting holes 31; optionally, the fixing holes 112 are threaded holes. In other embodiments, the fixing holes 112 can also be pin holes, interference fit holes, etc., which are not limited here. The fixing holes 112 on the outer surface of the shaft 111 end correspond one-to-one with the limiting holes 31 on the pressure plate 3, allowing the shaft 111, pressure plate 3, and cover plate 12 to be directly fixedly connected by fasteners. This design further optimizes the integrated structure of the bearing and reduces assembly complexity; the precise correspondence of the hole positions ensures the fit between the shaft 111, pressure plate 3, and cover plate 12, improving the stability of the overall structure.

[0056] In some possible embodiments of this utility model, such as Figure 1 As shown, a fastener 32 is provided on one outer surface of the pressure plate 3; the fastener 32 passes through the pressure plate 3, sleeves the limiting hole 31 on the pressure plate 3, and is fixedly connected to the fixing hole 112 of the corresponding hole on the shaft 111; the cover plate 12 is limited between the pressure plate 3 and the shaft 111; the fastener 32 must be adapted to the limiting hole 31 and the fixing hole 112. Optionally, the fastener 32 can be a threaded nail, which passes through the limiting hole 31 without contact, and limits the pressure plate 3 axially. The threaded pin and the pressure plate 3 limit the cover plate 12 from the axial direction and the vertical direction of the axis, respectively. A movable gap is left between the pressure plate 3 and the cover plate 12 to prevent the cover plate 12 from being fixed. The threaded pin passes through the limiting hole 31 and enters the fixing hole 112 corresponding to the limiting hole 31. When the threaded pin is screwed to abut against the bottom of the fixing hole 112 on the shaft 111, the pressure plate 3, the cover plate 12 and the base 11 form an integrated structure. In other embodiments, the fastener 32 can also be a bolt, pin, rivet, etc., which is not limited here. Fasteners 32, provided on one outer surface of pressure plate 3, pass through limiting holes 31 on cover plate 12 and are fixedly connected to fixing holes 112 on shaft 111, limiting cover plate 12 between pressure plate 3 and shaft 111, so that cover plate 12, base 11 and pressure plate 3 form an integrated structure; the connection method of fasteners 32 forms a rigid constraint between pressure plate 3 and shaft 111, and firmly limits cover plate 12 axially, effectively avoiding relative displacement between components, and the pressure bearing can stably and reliably transmit load.

[0057] In some possible embodiments of this utility model, such as Figure 1As shown, an annular groove 122 is provided on the outer surface of the cover plate 12 facing the pressure plate 3 along the outer edge of the shaft adapter hole 121. The inner diameter of the annular groove 122 is not less than the outer diameter of the shaft body 111, and the outer diameter of the annular groove 122 is not less than the outer diameter of the pressure plate 3. The pressure plate 3 is embedded in the annular groove 122. Understandably, the axial relative positions of the pressure plate 3 and the cover plate 12 are fixed, and the pressure plate 3 is loosely embedded in the annular groove 122, which avoids the pressure plate 3 being squeezed by the pressure body 5 and thus damaging the pressure bearing. The annular groove 122 on the side of the cover plate 12 facing the pressure plate 3, with its inner diameter adapted to the shaft 111 and its outer diameter accommodating the pressure plate 3, allows the pressure plate 3 to be fitted into the annular groove. This structural design further ensures a tight fit between the pressure plate 3 and the base 11, axially limiting the cover plate 12 between the pressure plate 3 and the base 11, forming a stable, integrated connection structure. The fitting of the annular groove 122 with the pressure plate 3 increases the contact area between the components, resulting in uniform pressure distribution and effectively preventing localized stress concentration. Figure 3 As shown, this interlocking method provides dual circumferential and radial limits for the pressure plate 3, so that when the cover plate 12 and the base 11 rotate relative to each other, the components maintain a relatively fixed positional relationship. In addition, interlocking the pressure plate 3 in the annular groove of the cover plate 12 is also beneficial to the connection and fixation of the cover plate 12 and the pressure body connected to it, thereby enhancing the stability and reliability of the overall structure.

[0058] In some possible embodiments of this utility model, such as Figure 3 , Figure 4 As shown, a first outer ring 113 is provided on the outer peripheral surface of the shaft 111 extending axially towards the cover plate 12, and a first groove 114 is formed between the first outer ring 113 and the shaft 111; a second outer ring 123 is provided on the outer peripheral surface of the shaft adapter hole 121 extending axially towards the base 11, and a second groove 124 is formed between the second outer ring 123 and the shaft adapter hole 121; the friction cavity 13 is formed by the first groove 114 and the second groove 124. Optionally, the first groove 114 and the second groove 124 are grooves with a semi-circular cross-section, and the first groove 114 and the second groove 124 together form a circular cross-section, which facilitates the rolling element 2 to minimize friction and roll within the formed friction cavity 13; in other embodiments, the cross-sectional curvature of the first groove 114 and the second groove 124 can also be set to various sizes to meet the applicability of different rolling elements 2, which is not limited here. Its beneficial effect is that the first groove 114 of the shaft 111 and the second groove 124 on the cover plate 12 precisely abut against each other, directly forming a friction cavity 13. The friction cavity 13 provides a precise running track for the rolling element 2, so that the rolling element is subjected to uniform force when bearing load, which enhances the overall bearing capacity and impact resistance of the bearing and reduces the risk of equipment failure caused by loose connection or unstable structure.

[0059] In some possible embodiments of this utility model, such as Figure 3 As shown, several of the rolling elements 2 are spheres. The advantage of this design is that, as rolling elements 2, the spheres can achieve point contact rolling with the contact surfaces of the base 11 and cover plate 12 within the friction cavity 13 formed by the base 11 and cover plate 12. The load-bearing capacity of the spheres is relatively balanced in all directions. This contact method allows the base 11 and cover plate 12 to experience more uniform force during relative rotation. When the pressure bearing bears external loads, the spheres can evenly distribute the force to the base 11 and cover plate 12, avoiding localized stress concentration that could lead to component damage. Compared to the uneven stress introduced by the transition parts in traditional split bearings, this design further enhances the overall integrated connection stability of the bearing. When the spheres roll, compared to other rolling elements such as cylinders, their rolling friction coefficient is smaller, allowing them to move within the friction cavity with minimal resistance, thus improving the bearing's rotational efficiency.

[0060] To solve the above problems, this utility model also provides a rotational bearing structure, such as... Figure 4 , Figure 5 As shown, it includes: the aforementioned integrally connected pressure bearing.

[0061] To better illustrate the rotating bearing structure of this utility model, the following specific application will be used as an example: The rotating bearing structure of this utility model consists of an integrally connected pressure bearing base 11 and cover plate 12, which are directly fixedly connected to the support body 4 and pressure body 5 through mounting holes 115 and 125 provided on the base 11 and cover plate 12, respectively. This eliminates the traditional connection method of separate bearings that relies on adapters, avoiding assembly gaps and loosening risks introduced by adapters, and making the pressure bearing and equipment form a stable whole. During equipment operation, the relative rotation of the base 11 and cover plate 12 can stably drive the support body 4 and pressure body 5 to rotate synchronously, ensuring more stable force transmission. By directly assembling the bearing base 11 with the support body 4 and the cover plate 12 with the pressure body 5, the connection structure is simplified, connection steps are reduced, installation complexity is lowered, and the efficiency of integrating the pressure bearing with the equipment is greatly improved.

[0062] In some possible embodiments of this utility model, such as Figure 4 , Figure 5As shown, the base 11 has first mounting holes 115 at the four corners of its outer periphery for fixed connection with the support body 4; the cover plate 12 has second mounting holes 125 at the four corners of its outer periphery for fixed connection with the pressure body 5. The advantage is that the base 11 and cover plate 12 can be directly fixed to the support body 4 and pressure body 5 through the first mounting holes 115 and second mounting holes 125 at the four corners of their outer periphery, respectively. This design abandons the traditional connection mode of separate pressure bearings that relies on adapters. The uniform layout of the mounting holes creates a stable integrated structure between the bearing and the equipment. The mounting holes at the four corners of the outer periphery of the base 11 and cover plate 12 create a symmetrical and uniform force distribution during connection, avoiding localized stress concentration. This layout effectively prevents loosening or displacement between the bearing and the equipment, ensuring that the relative rotation of the base and cover plate stably drives the support body 4 and pressure body 5, thus enhancing the overall stability and reliability of the structure.

[0063] As described above, the integrated pressure bearing and rotating bearing structure of this utility model have the following beneficial effects: the cover plate is axially limited between the pressure plate and the base by the pressure plate, so that the pressure plate, the cover plate and the base form a stable integrated connection structure, which solves the problem of the separate structure design of the bearing base and the cover plate in the prior art. In addition, by directly setting the mounting holes on the base and the cover plate of the integrated pressure bearing, the problem of the bearing requiring an additional adapter to connect to the equipment in the prior art is solved.

[0064] Therefore, this utility model effectively overcomes various technical problems in the prior art and has high industrial application value.

[0065] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
