Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical engineering, in particular to an emergency replacement component for online treatment of roller bearing failure. Background Art
[0002] The installation position of the working roller in front of the roughing mill of the hot rolling mill production line is complex. The surrounding equipment includes the front guide device, descaling pipe, descaling box cover, roller cooling water, etc. Under the harsh working conditions, the conveyor roller is subjected to huge load and impact force. Long-term heavy-load operation leads to an increasing frequency of abnormal failures.
[0003] In the hot rolling production line, roller bearing failure is the most common and typical failure. The roller bearing skeleton oil seal is very easy to be damaged, resulting in poor roller lubrication, which can also cause bearing jamming and dead roller. For the roller jamming problem caused by bearing failure, the best solution is to replace the roller assembly as a whole, but the overall maintenance and replacement has a certain cycle and requires downtime. If only the bearing in the bearing seat of the dead roller is replaced, a higher installation accuracy is required. At the same time, the installed bearing needs to be heated, which takes a long time. Especially for rollers in complex locations, the replacement time is immeasurable, and there are no emergency replacement parts to replace the bearings temporarily, which affects the work progress. In serious cases, it directly affects the production of the rolling line and restricts the improvement of product quality. Utility Model Content

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.
[0030] Example 1
[0031] Reference Figures 1 to 5, which is the first embodiment of the utility model, provides an emergency replacement component for online disposal of roller bearing failure, which solves the problem of long waiting time for repair completion caused by roller jam, and includes a stabilizing component 100 and a balancing component 200.
[0032] Specifically, the stabilizing assembly 100 includes a stabilizing member 101 and a connecting member 102, wherein the connecting member 102 is fixedly disposed outside the stabilizing member 101 and the connecting member 102 is in contact with and connected to the roll neck; and,
[0033] Furthermore, the balancing assembly 200 includes a balancing member 201 and a flow guide member 202 . The balancing member 201 is fixedly mounted on one end of the outer side of the stabilizing member 101 , and the flow guide member 202 is disposed on the inner wall of the balancing member 201 .
[0034] When using, Figure 1 , A is the roller, B is the stabilizing component 100. When the working roller table in front of the machine has a dead roller problem, the worker needs to solve the dead roller problem in time to avoid affecting the working efficiency of the roller table and failing to feed the steel billet. The worker first uses oxygen cutting to destructively remove the damaged bearing in the inner cavity of the bearing seat, then grinds the inner cavity of the bearing seat with a grinder, and then quickly presses the stabilizing component 101, such as Figure 2 , a is the bearing installed in the bearing seat, b is the emergency component pressed into the bearing seat, so that it replaces the support work of the bearing, so that the roller table resumes normal work and reduces the downtime of the rolling line and the consumption of manpower and material resources.
[0035] The connector 102 is installed on the outside of the stabilizing member 101. When the worker presses the stabilizing member 101, the connector 102 is in contact with the roll neck. During the operation of the roller table, the worker injects grease into the inner cavity of the bearing seat through the end cover of the bearing seat and stores it in the balance member 201. The grease in the grease can be transported to the friction contact surface between the inner circle, outer circle and the other side of the component and the roll neck and the inner wall of the bearing seat through the guide member 202 as the grease rotates, effectively reducing the friction coefficient and improving the wear problem.
[0036] In actual situations, when a dead roll occurs, if the roller assembly is replaced as a whole, the entire line needs to be shut down for about 16 hours to dismantle and reinstall the front guide plate, descaling box cover, roller assembly and other equipment, which consumes a lot of manpower and material resources and restricts the release of the rolling line's production capacity. If the bearing is replaced online, it will take 8 hours. The bearing needs to be heated in the early stage to facilitate subsequent installation. After it cools down, the inner ring of the bearing is in close contact with the roller neck. This process takes a long time. In addition, due to the narrow space at the operating position, the bearing installation accuracy cannot be effectively guaranteed. Secondary damage is very likely to occur within a certain period of time, which increases the cost of spare parts procurement and wastes time, manpower and material resources. Therefore, the use of emergency replacement parts for roller bearing failures online can greatly reduce the downtime of the rolling line and the consumption of manpower and material resources. When the next maintenance cycle arrives, the roller can be replaced as a whole for offline repair during the ample planned downtime.
[0037] As a preferred solution, the stabilizing component 100 selects a nylon plate with a thickness consistent with the width of the roller bearing, and processes the nylon plate into a ring shape according to the inner diameter and outer diameter of the bearing. Nylon is cheap and easy to process. Nylon itself has high mechanical strength, high softening point, wear resistance, self-lubrication, and good shock absorption performance. It can minimize the wear of contact surfaces such as the roller neck and the inner cavity of the bearing seat, and can be used repeatedly on the line many times, reducing costs.
[0038] Example 2
[0039] Reference Figure 1 to Figure 5 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment:
[0040] Specifically, the stabilizing member 101 includes a supporting block 101a and a through hole 101b. The supporting block 101a is cylindrical. The through hole 101b is opened at the axial center of the supporting block 101a. The through hole 101b penetrates the supporting block 101a. The connecting member 102 is installed on the inner wall of the through hole 101b.
[0041] Furthermore, the connecting member 102 includes a connecting portion 102a, and the connecting portion 102a is installed inside the through hole 101b to increase the contact between the through hole 101b and the roll neck.
[0042] Preferably, there are multiple connecting portions 102a, which are equidistantly distributed inside the through hole 101b, corresponding to the groove on the roller neck, and there is a certain gap between them.
[0043] Preferably, the balancing member 201 includes an oil storage tank 201a, and the oil storage tank 201a is disposed at one end of the outer side of the supporting block 101a.
[0044] Furthermore, there are multiple oil storage tanks 201a, which are equidistantly arranged at one end of the outer side of the support block 101a.
[0045] During use, when a dead roller problem occurs, the worker first removes the damaged bearing from the inner cavity of the bearing seat, then polishes the inner cavity of the bearing seat, and then quickly presses the support block 101a, and moves the through hole 101b along the outer wall of the roller neck, so that the fixing piece 101 replaces the position of the bearing to support the rotation of the roller, so that the roller table resumes normal operation.
[0046] When workers are installing, the inner wall of the through hole 101b moves inward along the outer wall of the roller neck, that is, the support block 101a moves closely against the inner wall of the bearing seat, and a small gap is left with the end of the bearing seat away from the end cover. In order to achieve the purpose of rapid press-fitting of components on site at room temperature, the through hole 101b and the roller neck are matched with clearance fit, and during the process, it is necessary to ensure that the through hole 101b and the roller neck have good centering and coaxiality. That is, the connecting part 102a is installed on the inner wall of the through hole 101b, and the number is multiple, thereby increasing the contact between the through hole 101b and the roller neck, making it contact and connected with the roller neck, so that the roller can be supported by the through hole 101b on the support block 101a to achieve rotation.
[0047] After the worker installs the end cover, there is a small gap between the end cover and the oil storage tank 201a. During the operation of the roller, the worker injects grease into the inner cavity of the bearing seat through the lubrication hole on the end cover of the bearing seat. The residual grease can flow into the oil storage tank 201a during the rotation process for temporary storage. At the same time, the grease can flow to part of the friction contact surface of the inner seat of the bearing as it rotates, effectively reducing the friction coefficient and improving the wear problem.
[0048] As a preferred solution, there are four oil storage tanks 201a, with the axial center of the through hole 101b as the rotation center, the rotation path is a circle, and the oil storage tanks 201a are equidistantly distributed at one end of the outer side of the support block 101a.
[0049] Example 3
[0050] Reference Figure 1 to Figure 7 , which is the third embodiment of the utility model, and this embodiment is based on the previous embodiment:
[0051] Specifically, the guide member 202 is installed on the inner wall of the oil storage tank 201a. The guide member 202 includes an oil through hole 202a. The oil through hole 202a is arranged on the inner side of the support block 101a. The oil through hole 202a passes through the support block 101a.
[0052] Furthermore, there are multiple oil holes 202a distributed on the inner wall of the oil storage tank 201a.
[0053] Preferably, the oil through hole 202a is connected to the oil storage tank 201a, and the grease in the oil storage tank 201a can enter part of the friction contact surface through the oil through hole 202a.
[0054] Furthermore, the oil storage tank 201a is fan-shaped and distributed in a hub-like manner.
[0055] During use, when a dead roller problem occurs, the worker quickly presses the support block 101a to restore the rotation of the roller after cleaning the damaged bearing in the inner cavity of the bearing seat. The through hole 101b moves along the outer wall of the roller neck, so that the fixing member 101 replaces the bearing support work, so that the roller can resume normal rotation. When the roller rotates, the worker injects grease into the inner cavity of the bearing seat through the lubrication hole on the end cover of the bearing seat. The residual grease can flow into the oil storage tank 201a during the rotation process. During the rotation of the oil storage tank 201a, the grease enters the inner circle, outer circle and the other side of the support block 101a through the oil hole 202a on the inner wall and the friction contact surface with the roller neck and the inner wall of the bearing seat, thereby improving the friction and wear problem caused by the rotation.
[0056] As a preferred solution, the number of oil holes 202a is twelve, and each oil storage tank 201a corresponds to three oil holes 202a, which are respectively arranged on the top surface, bottom surface and the side away from the end cover of the oil storage tank 201a, and penetrate the support block 101a, so that the grease can enter the friction contact surface through the oil holes 202a. At the same time, the grease can also reach the front and rear friction surfaces of the bearing seat, reducing the friction loss generated when the support block 101a is driven to rotate and the bearing seat. When there is too much grease, it can also enter the oil storage tank 201a through the oil holes 202a for temporary storage. The number of oil storage tanks 201a is set to four, with the axial center of the through hole 101b as the rotation center, and the rotation path is a circle, which is equidistantly distributed at one end of the outer side of the support block 101a to balance the oil supply of the inner cavity of the bearing seat. In addition, the hub-type fan-shaped semi-groove design can not only meet the load-bearing capacity but also reduce the weight of the components, while also having the storage and transportation functions of grease.
[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
