DETAILED DESCRIPTION
[0016] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.
[0017] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0018] like Figures 1 to 4As shown, a tool that can effectively disassemble the gear of the reducer includes a supporting base plate 1 and a fixing ring 2 located above the supporting base plate, the right side of the supporting base plate and the right side of the fixing ring are connected by an intermediate connecting plate 3, the height distance between the fixing ring and the supporting base plate is 8~12cm, and a gear inlet and outlet opening 4 located on the left side of the intermediate connecting plate is formed between the fixing ring and the supporting base plate, and a clearance groove 5 that runs through the left side of the supporting base plate is provided in the middle of the supporting base plate; a fixing plate 6 is welded to the upper side of the fixing ring, a through hole is provided in the middle of the fixing plate, a fixing nut 7 is welded above the through hole, a threaded push rod 11 that matches the thread of the fixing nut is provided in the middle of the fixing nut, and the threaded push rod passes downward through the through hole. When using the tool, remove the upper cover of the reducer, and then extend the tool from the upper opening of the reducer, as shown in FIG. Figure 4 As shown, the gear enters the middle of the tool from the gear inlet and outlet opening 4, and the gear shaft passes through the makeshift groove 5 in the middle of the supporting bottom plate. The tool is lifted so that the supporting bottom plate is close to the lower end of the gear. Then, the operating rod is used to pass through the screwing ring to drive the threaded push rod to rotate, so that the lower end of the threaded push rod is against the upper end of the gear shaft. The threaded push rod is continued to be rotated, and the gear can be slowly lifted upward until it is taken out from the upper end of the gear shaft.
[0019] The tool has a simple structure, is easy to manufacture, and is convenient to use. It can quickly disassemble the gears of the reducer, saving time and effort, and will not cause damage to the reducer housing and the gears.
[0020] In this embodiment, the lower end of the threaded push rod is provided with a tip, and the upper end is provided with a screwing ring 8. The screwing ring 8 is provided to facilitate the rotation of the threaded push rod, and the operating rod is passed through the screwing ring to rotate the threaded push rod, which is more labor-saving and easy.
[0021] In this embodiment, the support base plate is circular, and a groove 9 is provided at a position corresponding to the notch of the clearance groove. The cross section of the intermediate connecting plate is arc-shaped. The main structure formed by the entire support base plate, the fixing ring and the intermediate connecting plate is designed to be approximately cylindrical, which can reduce the volume of the main structure as much as possible, making it easy to insert into the reducer, and at the same time reduce the edges and corners of the outer periphery of the main structure, so that it is not easy to bump against the reducer case and the hands of workers.
[0022] In this embodiment, arc-shaped reinforcing plates 10 are welded on both sides of the support base plate, and the lower end of the intermediate connecting plate and the edge of the support base plate are welded together; the arc-shaped reinforcing plate, the intermediate connecting plate and the fixing ring are an integrated structure, and only the round steel pipe is formed by cutting, so the overall strength is high and it is easy to manufacture.
[0023] In this embodiment, the outer diameter of the fixing ring, the diameter of the supporting base plate and the outer side diameter of the intermediate connecting plate are the same and are all 10~15cm. The diameter of the threaded top rod is 1.5~2.0cm. The tool can manufacture multiple different sizes and specifications, which can be selected according to the size of the reducer.
[0024] Unless otherwise stated, any technical solution disclosed in the above utility model, if it discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Any technician in the field should understand that the preferred numerical range is only a numerical value with a more obvious technical effect or representative value among many feasible numerical values. Since there are too many numerical values to be exhaustive, the utility model discloses only some numerical values to illustrate the technical solution of the utility model, and the numerical values listed above should not constitute a limitation on the scope of protection of the utility model.
[0025] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except when it is obviously impossible to use an one-piece molding process).
[0026] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above-mentioned utility model include states or shapes that are approximate, similar or close thereto.
[0027] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.
[0028] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
