Description

Technical Field

[0001] The invention relates to the field of bearing seat bearing equipment, and in particular to a continuous casting roller bearing seat bearing assembly equipment and a method for increasing the bearing load. Background Art

[0002] During operation, the bearing seat and bearing assembly equipment on the continuous casting roller is in a state of heavy load and high temperature. The inner and outer rings of the bearings are often crushed, causing the continuous casting machine to be forced to stop production. The reason is that the inner and outer rings of the bearings are thinner and narrower, and they are easily crushed when they are in a state of heavy load and high temperature. The position space occupied by the continuous casting roller bearing seat and bearing assembly equipment in the continuous casting machine cannot be changed, so the shape of the bearing seat and the bearing can only be changed in its own internal space to increase the bearing load to avoid the inner and outer rings of the bearing being crushed. Summary of the invention

[0003] The purpose of the present invention is to provide a continuous casting roller bearing seat bearing combination device and method for increasing the bearing load, which is used to replace the original continuous casting roller bearing seat bearing combination device and increase the bearing load without changing the internal installation space of the continuous casting machine.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0007] The device is installed inside the continuous casting machine.

[0008] The manufacturing method of the continuous casting roller bearing seat bearing assembly device with increased bearing load is to expand the bearing accommodation space inside the bearing seat, expand the bearing size, and increase the bearing load without changing the external shape and size of the bearing seat; the specific method is as follows:

[0009] 1) When machining the bearing seat, the outer dimensions of the bearing seat remain unchanged, the cooling water channel in the bearing seat is machined normally, and the inner hole diameter of the bearing seat is enlarged. The inner hole of the bearing seat is used to install the bearing. At this time, due to the enlarged diameter of the inner hole of the bearing seat, the partition wall between the inner hole of the bearing seat and the cooling water channel is destroyed. The middle position of the upper half of the bearing seat is cut off in a direction perpendicular to the axis of the bearing seat to machine a notch;

[0010] The outer dimensions of the bearing seat match the internal installation space of the continuous casting machine. Since the installation space in the continuous casting machine cannot be expanded or changed, the outer dimensions of the bearing seat do not change.

[0011] According to conventional technology, a cooling water channel is machined inside the bearing seat and outside the bearing mounting inner hole, and then the bearing seat inner hole is machined inside the cooling water channel. When machining the inner hole, the isolation wall between the inner hole and the cooling water channel will be destroyed.

[0012] 2) Increase the thickness and width of the outer ring of the bearing, increase the size of the rolling element, increase the thickness and width of the inner ring of the bearing, and keep the inner diameter of the bearing unchanged; the outer ring diameter of the bearing matches the inner hole diameter of the bearing seat;

[0013] 3) Process internal threads on both sides of the bearing seat;

[0014] 4) Install the bearing into the bearing seat from the side, and seal and weld the outer ring of the bearing to the inner edge of the notch;

[0015] 5) Processing an arc-shaped steel plate that matches the shape and size of the outer wall of the bearing seat notch, sealing and welding the arc-shaped steel plate to the bearing seat, and connecting the channel between the arc-shaped steel plate and the outer ring of the bearing to the cooling water channel in the bearing seat;

[0016] 6) Install the bearing caps onto the bearing seat from both sides of the bearing seat.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1) The bearing of the present invention is enlarged, its inner and outer rings are thickened and widened, the rolling elements are enlarged, and the bearing load is greatly increased.

[0019] 2) The circulating water is close to the outer ring of the bearing to increase the cooling effect.

[0020] 3) The bearing cover and bearing seat are connected with threads to facilitate oil filling and sealing.

[0021] 4) Without changing the internal installation space of the continuous casting machine, the load-bearing capacity is greatly increased and the service life is extended. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention is described in detail below, but the implementation scope of the present invention is not limited to the following embodiments.

[0031] like Figure 1-Figure 7 As shown, a continuous casting roller bearing seat bearing assembly device for increasing the bearing load-bearing capacity includes a bearing seat 1 and a bearing 2. A cooling water channel 1-2 is provided in the bearing seat 1; a notch is provided in the middle position of the upper half of the bearing seat 1, and the opening direction of the notch is perpendicular to the axis of the bearing seat. The bearing outer ring 2-1 placed inside the bearing seat 1 is seal-welded to the inner edge of the notch, and an arc-shaped steel plate 3 is seal-welded to the outside of the notch of the bearing seat 1. The channel formed by the arc-shaped steel plate 3 and the bearing outer ring 2-1 is connected to the cooling water channel 1-2 in the bearing seat 1.

[0032] It also includes a bearing cover 4, an inner end 4-1 of which is machined with an external thread matching the internal thread of the bearing seat 1, and the bearing cover 4 is connected to both sides of the bearing seat 1 through threads.

[0033] The device is installed inside the continuous casting machine.

[0034] A method for manufacturing a continuous casting roller bearing seat bearing assembly device with increased bearing load, which expands the accommodation space of the bearing 2 inside the bearing seat 1, expands the size of the bearing 2, and increases the bearing load of the bearing 2 without changing the external shape and size of the bearing seat 1; the specific method is as follows:

[0035] 1) When processing the bearing seat 1, the outer dimensions of the bearing seat 1 remain unchanged, the cooling water channel 1-2 in the bearing seat 1 is processed normally, and the diameter of the inner hole 1-1 of the bearing seat is enlarged. The inner hole 1-1 of the bearing seat is used to install the bearing 2. At this time, since the diameter of the inner hole 1-1 of the bearing seat is enlarged, the partition wall between the inner hole 1-1 of the bearing seat and the cooling water channel 1-2 is destroyed. The middle position of the upper half of the bearing seat 1 is cut off in a direction perpendicular to the axis of the bearing seat 1 to process a notch;

[0036] The outer dimensions of the bearing seat 1 match the internal installation space of the continuous casting machine. Since the installation space in the continuous casting machine cannot be expanded or changed, the outer dimensions of the bearing seat 1 do not change.

[0037] According to conventional technology, a cooling water channel 1-2 is processed inside the bearing seat 1 and outside the bearing installation position, and then the bearing seat inner hole 1-1 is processed inside the cooling water channel 1-2. When processing the bearing seat inner hole 1-1, the isolation wall between the bearing seat inner hole 1-1 and the cooling water channel 1-2 will be damaged.

[0038] 2) Increase the thickness and width of the bearing outer ring 2-1, increase the size of the rolling element 2-2, increase the thickness and width of the bearing inner ring 2-3, and keep the inner diameter of the bearing 2 unchanged; the diameter of the bearing outer ring 2-1 matches the diameter of the bearing seat inner hole 1-1;

[0039] 3) Process internal threads on both sides of the bearing seat 1;

[0040] 4) Install the bearing 2 into the bearing seat 1 from the side, and seal and weld the bearing outer ring 2-1 to the inner edge of the notch;

[0041] 5) Processing an arc-shaped steel plate 3 that matches the shape and size of the outer wall of the notch of the bearing seat 1, sealingly welding the arc-shaped steel plate 3 to the bearing seat 1, and connecting the channel between the arc-shaped steel plate 3 and the bearing outer ring 2-1 to the cooling water channel 1-2 in the bearing seat 1;

[0042] 6) Install the bearing cover 4 onto the bearing seat 1 from both sides of the bearing seat 1.

[0043] The bearing seat 1 of the present invention can be regarded as a layer of the original bearing seat inner hole 1-1 is machined off to expand the diameter of the bearing seat inner hole 1-1 so that a larger bearing 2 can be placed. Then, a piece of the upper part is planed off along the direction perpendicular to the axis of the bearing seat inner hole 1-1 to the middle surface H of the bearing seat inner hole 1-1, and a side edge 1-3 is left on each side. The bearing 2 placed therein is welded to the inner side of the side edges 1-3 on both sides and the inner side of the side edge connection surface 1-4, so that the bearing 2 can be fixed and sealed, and the cooling water cannot flow into the bearing 2. The inner threads are machined at both ends of the bearing seat inner hole 1-1 to facilitate connection with the bearing cover 4. The bearing 2 can be regarded as an enlargement of the original bearing, and its bearing inner ring 2-3 and bearing outer ring 2-1 are thickened and widened, and the rolling element 2-2 is enlarged. The inner diameter of the bearing 2 remains unchanged, which can greatly increase the bearing load of the bearing 2. The outer arc surface 3-1 of the arc steel plate is consistent with the outer arc surface of the bearing seat 1. The width of the arc steel plate 3 is the same as the width of the planed notch, and the thickness is the same as the thickness of the outer wall of the bearing seat 1. It is welded in the notch between the two side edges 1-3 of the bearing seat 1. There is a certain gap between the inner arc surface 3-2 of the arc steel plate and the outer ring 2-1 of the bearing, which is connected to the cooling water channel 1-2 so that water can flow to cool the bearing 2. The inner end 4-1 of the bearing cover 4 is threaded with an outer thread that matches the inner thread of the inner hole 1-1 of the bearing seat so as to be connected thereto.
