Description

Technical Field

[0001] This utility model relates to the field of bearing seal cleaning technology, and in particular to a support device for auxiliary cleaning of bearing seals. Background Technology

[0002] After cleaning, railway freight car bearing seals must be free of dirt and rust. Currently, the common process involves soaking the seals in solvents like kerosene and gasoline for at least six hours, followed by manual cleaning – a very outdated and inefficient method. Some companies have opted to purchase automatic seal cleaning machines, similar in principle to railway freight car bearing body cleaning machines. These machines use water-based metal cleaners and employ 75°C high-temperature steaming and all-around spraying, completing the cleaning process automatically, quickly, and with high quality through initial washing, fine washing, and machine drying. However, this approach significantly increases costs as the automatic seal cleaning machine is a proprietary piece of equipment (approximately 150,000 RMB). Furthermore, the bearing body is much larger than the bearing seal, and existing bearing body cleaning machines generally lack a suitable support device to assist in cleaning the bearing seal. Currently, no suitable auxiliary tooling design or purchase channels have been found.

[0003] Therefore, it is worthwhile to study how to design a machine that can position and support the bearing seal so that it can be placed into an existing bearing body cleaning machine for cleaning the bearing seal. Utility Model Content

[0004] The purpose of this utility model is to provide a support device for auxiliary cleaning of bearing seal seats. It is made from the outer ring of a waste bearing. Its design is simple, practical and durable. Multiple bearing seal seats to be cleaned can be positioned and placed at the same time using the support column, so that it can be adapted to be placed in the existing bearing body cleaning machine. It has low manufacturing cost, short cycle and convenient use, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A support device for auxiliary cleaning of bearing seal housing includes a hollow cylindrical support with open ends. A bracket is provided at one open end of the support, and the bracket is fixedly fitted with several support columns for positioning and supporting the bearing seal housing to be cleaned. Each support column is located within the inner cavity of the support, and a receiving space for inserting the bearing seal housing to be cleaned is formed between the support column and the inner sidewall of the support. The distance from each support column to the central axis of the support is equal.

[0007] Furthermore, the surface of the support away from the bracket is flush with the surface of the support column away from the bracket.

[0008] Furthermore, the support is a used bearing outer ring.

[0009] Furthermore, the support column is a cylindrical metal rod.

[0010] Furthermore, the number of support columns is set to four.

[0011] Furthermore, the four support columns are arranged in a rectangular pattern.

[0012] Furthermore, the support columns are arranged in a circular array along the central axis of the support.

[0013] Furthermore, the bracket is a U-shaped bracket, which includes two parallel steel plates, the two ends of which are fixedly connected to the edge of the support.

[0014] Furthermore, the bracket is a cross-shaped bracket, which includes two vertically distributed steel plates connected at the middle, and the two ends of the two steel plates are respectively fixedly connected to the edge of the support.

[0015] Furthermore, the steel plate is fixedly connected to the support by welding.

[0016] Compared with the prior art, the present invention provides a support device for auxiliary cleaning of bearing seals, which has the following advantages:

[0017] (1) This utility model is made by welding waste bearing outer rings, steel plates, metal rods, etc. It is simple in design, practical and durable, low in production cost, short in cycle and easy to use.

[0018] (2) When using this utility model, multiple bearing seal seats to be cleaned can be positioned and placed simultaneously using the support column, so that it can be adapted to be placed in the existing bearing body cleaning machine. Thus, the existing bearing body cleaning machine can be used to automatically clean the bearing seal seats, saving about RMB150,000 in cost of purchasing a separate bearing seal seat cleaning machine. At the same time, since it can be adapted to the bearing body cleaning machine, more environmentally friendly cleaning agents can be used for the cleaning of the seal seats, greatly reducing the use of kerosene and gasoline. It can save about 500 kg of kerosene and gasoline per month, and save more than RMB3,500 in fixed production costs. In addition, the cleaning site environment is significantly improved, effectively reducing the physical harm to operators during the cleaning process using kerosene.

[0019] (3) Using the support device of this utility model, it only takes 22.5 seconds to complete the cleaning of each bearing seal seat. The cleaning effect is good and the efficiency is high. It greatly reduces the cleaning time of the bearing seal seat, greatly improves the cleaning quality of the bearing seal seat, and effectively ensures the quality of bearing maintenance.

[0020] In addition, relevant usage data was collected through two consecutive months of on-site use, especially the durability of the support device and the consistency of the bearing seal cleaning quality. The tracking results showed that the support device was very durable in actual use. After two months of use, none of the 30 support devices made in the workshop showed any damage or deformation. The efficiency and quality of bearing seal cleaning were also guaranteed. During the two months, the workshop cleaned an average of about 165 sets of Type 26 bearings per day, which were all completed smoothly within normal working hours, without any overtime or delays in cleaning.

[0031] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0032] Example 1

[0033] Please refer to Figures 1-4 This embodiment provides a support device for auxiliary cleaning of bearing seal seats, including a cylindrical hollow support 1 with open ends; a bracket 2 is provided at one open end of the support 1, and a plurality of support columns 3 are fixedly installed on the bracket 2 for positioning and supporting the bearing seal seat 5 to be cleaned. Each support column 3 is located in the inner cavity of the support 1, and a receiving space 4 for inserting the bearing seal seat 5 to be cleaned is formed between the support column 3 and the inner side wall of the support 1. The distance from each support column 3 to the central axis of the support 1 is equal. Thus, when the support device with the bearing seal seat installed is placed into an existing bearing body cleaning machine at a vertical placement angle, the various support columns provide circumferential rotation support during the cleaning process of the bearing seal seat, and also provide longitudinal movement support during the automatic conveying and movement process.

[0034] In some specific implementations, support 1 is a used bearing outer ring.

[0035] In some specific implementation methods, refer to Figure 1 and Figure 2 The bracket 2 is a U-shaped bracket, comprising two parallel steel plates 21. The ends of the two steel plates 21 are welded to the edge of the support 1. Specifically, as an example, the steel plates used in the U-shaped bracket have dimensions of 190mm*24mm*11mm.

[0036] In this embodiment, reference Figure 1 and Figure 2 Four support columns 3 are provided, arranged in a rectangular pattern. The center of the virtual circle containing each support column is located on the central axis of the support; specifically, for example, the diameter of the virtual circle is 118mm. Thus, four bearing seal seats can be cleaned simultaneously within 90 seconds, with excellent cleaning quality that fully meets requirements. The average cleaning time for each bearing seal seat is only 22.5 seconds, approximately 25% of the time required for conventional processes. This significant reduction in cleaning time for bearing seal seats achieves the goal of fast and effective cleaning.

[0037] In some specific embodiments, the support column 3 is a cylindrical metal rod. Specifically, as an example, the specifications of the support column are Φ12mm*139mm.

[0038] In a preferred embodiment, the surface of the support 1 away from the bracket 2 is flush with the surface of the support column 3 away from the bracket 2. Thus, after placing the support with the bearing seal seat installed onto the bearing body cleaning machine, on the one hand, interference caused by structural protrusions can be avoided, thus preventing interference with transmission; on the other hand, it can cooperate with the fixing and anti-falling device built into the bearing body cleaning machine to prevent the bearing seal seat from slipping off the support during cleaning or transport.

[0039] Example 2

[0040] This embodiment provides a support device with another structure for auxiliary cleaning of bearing seals. Unlike embodiment 1, it refers to... Figures 5-8 The support 2 is redesigned as a cross-shaped support, comprising two vertically distributed steel plates 21 connected at the middle, with their ends welded to the edge of the support 1. Correspondingly, four support columns 3 are arranged in a circular array along the central axis of the support 1. Specifically, as an example, the steel plates used in the cross-shaped support have dimensions of 217mm*24mm*11mm.

[0041] The method of using this utility model is as follows: Figure 3 or Figure 7 As shown, after the four bearing seal seats 5 are loaded onto the support device, they are placed vertically into the existing bearing body cleaning machine. They can be cleaned simultaneously with the bearing body (i.e., the disassembled bearing outer ring) in a production line. The general working principle is as follows: using a water-based metal cleaning agent, the cleaning process is carried out automatically, quickly, and with high quality through 75℃ high-temperature steaming and all-round spraying, followed by three steps: initial washing, fine washing, and machine drying.

[0042] This utility model is made from the outer ring of a scrap bearing. Its design is simple, practical, and durable. Multiple bearing seals to be cleaned can be positioned simultaneously using support columns, allowing it to fit into existing bearing cleaning machines. It has low manufacturing costs, short production cycles, and is easy to use. This utility model is applicable to the cleaning of seals for various bearing models, including railway SKF197726, 353130B, and 352226X2-2RZ bearings.

[0043] The above embodiments are merely illustrative of the concept and technical solution 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.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
