Technical Field
[0001] This application relates to the field of roll grinding technology, and in particular to a roll bearing device. Background Technology
[0002] After use, the rolls need to be ground. The rolls of the roll grinding machine are rotated by the support of the bearing device. The bearing device is a consumable part. The area in contact with the roll is a Babbitt alloy layer. The Babbitt alloy layer has low hardness and is easy to wear. After wear, the roll will have a misalignment. The height of the bearing device needs to be adjusted frequently. Moreover, the Babbitt alloy layer cannot be too thick. After wear, it needs to be replaced frequently. Utility Model Content
[0003] The main purpose of this utility model is to provide a roller support device to solve the problems of easy wear and misalignment and the need for frequent height adjustment in the existing roller support device.
[0004] To achieve the above objectives, this utility model provides a roll support device, comprising a first base, a second base, an intermediate mounting shaft, and a support mechanism, wherein...
[0005] The first base is spaced above the second base, and a vertical through hole is provided in the middle of the first base;
[0006] The second base body is recessed downwards and has a receiving groove corresponding to the vertical through hole. The receiving groove and the vertical through hole together form a receiving space around the intermediate mounting shaft.
[0007] The intermediate mounting shaft is fixed between the first base and the second base;
[0008] The supporting mechanism is located within the accommodating space and is rotatably mounted on the outer peripheral wall of the intermediate mounting shaft. The supporting mechanism is used to support the roll and move synchronously with the roll.
[0009] In one embodiment, the top surface of the first base is an upward-opening arc surface, and the vertical through hole is located in the middle of the arc surface.
[0010] In one embodiment, the supporting mechanism is a bearing, and the lowest point of the arc surface is flush with the height of the bearing at the corresponding position.
[0011] In one embodiment, the axial direction of the intermediate mounting shaft intersects with the bending direction of the arc surface.
[0012] In one embodiment, the intermediate mounting shaft includes a shaft body and a first axial stop structure. The first axial stop structure is sleeved on the outer peripheral wall of the shaft body. The first axial stop structure has a first positioning hole for a pin shaft to pass through. The shaft body has a second positioning hole corresponding to the first positioning hole. The pin shaft passes through the first positioning hole and the second positioning hole to prevent the shaft body from moving axially.
[0013] In one embodiment, the other end of the shaft opposite to the first axial stop structure further includes a second axial stop structure, the second axial stop structure protruding along the radial portion of the shaft, the second axial stop structure being located within the receiving space and abutting against the inner wall of the receiving space.
[0014] In one embodiment, the bearing is sleeved on the shaft and located between the first axial stop structure and the second axial stop structure.
[0015] In one embodiment, the shaft further includes a lubrication structure disposed inside the intermediate mounting shaft, including an oil inlet channel and an oil injection channel. The oil inlet channel is disposed along the axial direction of the shaft, and the oil injection channel is disposed along the radial direction of the shaft and connected to the oil inlet channel. There are multiple oil injection channels, which pass through the first axial stop structure and the second axial stop structure respectively and lead to the vertical through hole.
[0016] In one embodiment, the second seat also has an oil draining structure, one end of which is connected to the accommodating space and penetrates the side wall of the second seat.
[0017] In one embodiment, the connecting surfaces of the first base and the second base have keyways, and corresponding keys are installed in the keyways to restrict the relative movement between the first base and the second base.
[0018] In this embodiment of the application, when the roll support device is working, the supporting mechanism bears more pressure from the roll, which reduces the wear of the first seat body, thereby reducing the probability of the roll support device having centering deviation due to wear, reducing the number of times the height needs to be adjusted, and extending the service life of the roll support device.

[0027] In related technologies, the rolls of a roll grinding machine rotate with the support of a roll support device. This roll support device typically has a Babbitt alloy layer. This layer has low hardness and is easily worn, leading to misalignment of the rolls and requiring frequent adjustments to the height of the roll support device. Furthermore, because the thickness of the Babbitt alloy layer cannot be too large, it needs frequent replacement after wear, resulting in high costs.
[0028] This utility model provides a roll support device, including a first base 1, a second base 2, an intermediate mounting shaft 3, and a support mechanism 4, wherein...
[0029] The first base 1 is spaced above the second base 2, and a vertical through hole 11 is provided in the middle of the first base 1;
[0030] The second seat 2 is recessed downwards and has a receiving groove 21 corresponding to the vertical through hole 11. The receiving groove 21 and the vertical through hole 11 together form a receiving space around the central mounting shaft 3.
[0031] The intermediate mounting shaft 3 is fixed between the first seat 1 and the second seat 2;
[0032] The support mechanism 4 is located within the accommodating space and is rotatably mounted on the outer peripheral wall of the intermediate mounting shaft 3. The support mechanism 4 is used to support the roll and move synchronously with the roll.
[0033] It should be noted that the support mechanism 4 passes through the vertical through hole 11 on the first base body 1 and directly contacts the roll placed on the roll support device during operation.
[0034] In this embodiment, the intermediate mounting shaft 3 is fixed between the first seat 1 and the second seat 2, and the supporting mechanism 4 is rotatably mounted on the outer peripheral wall of the intermediate mounting shaft 3 and located within the accommodating space. This allows the supporting mechanism 4 to withstand the pressure of the roll as much as possible, reducing the wear of the roll on the first seat 1, thereby reducing the probability of the roll producing a centering deviation.
[0035] In one embodiment, the top surface of the first base 1 is an arc surface 12 with the opening facing upward, and a vertical through hole 11 is opened in the middle of the arc surface 12.
[0036] It should be noted that the first base 1 includes a first base and a Babbitt alloy layer, wherein the Babbitt alloy layer is located above the first base 1 and has an upward-opening arc surface 12, and the Babbitt alloy layer and the first base are connected by casting.
[0037] In this embodiment, the top surface of the first base 1 is an upward-opening arc surface 12, which can support the roller and allow it to rotate on the first base 1. A vertical through hole 11 is opened in the middle of the arc surface 12, and the support mechanism 4 located in the vertical through hole 11 is also located in the middle of the arc surface 12, which can bear the pressure of the roller in a relatively balanced manner, so that the roller can rotate smoothly on the first base 1.
[0038] In one embodiment, the supporting mechanism 4 is a bearing, and the lowest point of the arc surface 12 is flush with the bearing height at the corresponding position.
[0039] It is important to know that the bearing is a self-aligning roller bearing, which can withstand large radial loads and has a certain degree of self-aligning capability.
[0040] In this embodiment, the lowest point of the arc surface 12 is flush with the bearing height at the corresponding position. This allows the bearing to engage with the arc surface 12. When the roll rotates on the first seat 1, the arc surface 12 protects the roll in a relatively fixed position, while the bearing bears the load from the roll. This reduces wear on the arc surface 12 during roll rotation, thereby extending the service life of the device. The bearing is a self-aligning roller bearing, which can automatically adjust the misalignment of the roll. Even if there is misalignment during operation, the bearing can still function normally, reducing the need for frequent height adjustments of the bearing support device.
[0041] In one embodiment, the axial direction of the intermediate mounting shaft 3 intersects with the bending direction of the arc surface 12.
[0042] For example, the axial direction of the intermediate mounting shaft 3 is perpendicular to the curved square of the arc surface 12.
[0043] In this embodiment, the axial direction of the intermediate mounting shaft 3 is intersected with the bending direction of the arc surface 12, so that the rotation direction of the bearing mounted on the intermediate mounting shaft 3 is on the same plane as the rotation direction of the roll supported by the arc surface 12. That is, when the roll rotates, the bearing can rotate synchronously with the roll, thereby bearing more load from the roll.
[0044] In one embodiment, the intermediate mounting shaft 3 includes a shaft body 32 and a first axial stop structure 31. The first axial stop structure 31 is sleeved on the outer peripheral wall of the shaft body 32. The first axial stop structure 31 has a first positioning hole 311 through which a pin passes. The shaft body 32 has a second positioning hole 321 corresponding to the first positioning hole 311. The pin passes through the first positioning hole 311 and the second positioning hole 321 to prevent the shaft body 32 from moving axially.
[0045] In this embodiment, the first axial stop structure 31 is sleeved on the outer peripheral wall of the shaft 32, and the pin passes through the first positioning hole 311 and the second positioning hole 321 to prevent the shaft 32 from moving axially. This allows the first axial stop structure 31 to be more firmly sleeved on the shaft 32, reducing the relative movement between the first axial stop structure 31 and the shaft 32, and also allows the bearing to be installed more stably on the intermediate mounting shaft 3 without displacement.
[0046] In one embodiment, the other end of the shaft 32 opposite to the first axial stop structure 31 also includes a second axial stop structure 322. The second axial stop structure 322 protrudes along the radial portion of the shaft 32 and is located within the receiving space and abuts against the inner wall of the receiving space.
[0047] It should be noted that the second axial stop structure 322 and the first axial stop structure 31 abut against the inner walls on opposite sides of the receiving space.
[0048] In this embodiment, the shaft 32 also has a second axial stop structure 322. The second stop structure protrudes radially along the shaft 32 and abuts against the inner wall of the accommodating space. This allows the second axial stop structure 322 to cooperate with the first axial stop structure 31 to restrict the shaft 32 between the first seat 1 and the second seat 2, reducing the axial movement of the shaft 32 and enabling the device to operate smoothly.
[0049] In one embodiment, the bearing is sleeved on the shaft 32 and located between the first axial stop structure 31 and the second axial stop structure 322.
[0050] In this embodiment, the bearing is sleeved on the shaft 32 and located between the first axial stop structure 31 and the second axial stop structure 322. This restricts the bearing to a position between the second axial stop structure 322 and the first axial stop structure 31, reducing the probability of the bearing moving axially along the shaft 32 and improving the stability of the device.
[0051] In one embodiment, the shaft 32 further includes a lubrication structure 33, which is disposed inside the intermediate mounting shaft 3 and includes an oil inlet channel 331 and an oil injection channel 332. The oil inlet channel 331 is arranged along the axial direction of the shaft 32, and the oil injection channel 332 is arranged along the radial direction of the shaft 32 and connected to the oil inlet channel 331. There are multiple oil injection channels 332, which pass through the first axial stop structure 31 and the second axial stop structure 322 respectively and lead to the vertical through hole 11.
[0052] In this embodiment, the lubrication structure 33 is disposed inside the intermediate mounting shaft 3. The oil inlet channel 331 is disposed along the axial direction of the shaft body 32, and the oil injection channel 332 is disposed along the radial direction of the shaft body 32 and connected to the oil inlet channel 331. This facilitates oil injection. Multiple oil injection channels 332 are provided to provide more comprehensive lubrication to the first seat body 1 and improve the lubrication effect. The oil injection channels 332 lead to the vertical through hole 11 and do not contact the external space, which can reduce the pollution of the working environment by oil.
[0053] In one embodiment, the second seat 2 also has an oil draining structure 22, one end of which is connected to the accommodating space and penetrates the side wall of the second seat 2.
[0054] It should be noted that the oil drain structure 22 is a through hole that penetrates the side wall of the second seat body 2 and is provided on the second seat body 2.
[0055] In this embodiment, the oil draining structure 22 is connected to the accommodating space and penetrates the side wall of the second seat 2. This allows the lubricating oil accumulated in the accommodating space to flow out naturally through the oil draining structure 22, resulting in lower maintenance costs.
[0056] In one embodiment, the connecting surfaces of the first seat 1 and the second seat 2 have key 5 grooves, and corresponding keys 5 are installed in the key 5 grooves to limit the relative movement between the first seat 1 and the second seat 2.
[0057] In this embodiment, the connecting surfaces of the first seat 1 and the second seat 2 have key 5 grooves, and corresponding key 5 grooves are installed in the key 5 grooves to limit the relative movement between the first seat 1 and the second seat 2, so that the first seat 1 and the second seat 2 can be installed together relatively stably in the horizontal direction, and maintain the stable cooperation between the internal support mechanism 4 and the intermediate mounting shaft 3.
[0058] The above technical solutions of this utility model are merely preferred embodiments and do not limit the patent scope of this utility model. All equivalent structural transformations made under the technical concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of this utility model.
