Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil seals, in particular to a rotating shaft oil seal positioning device. Background Art
[0002] Oil seals are mechanical components used to seal oil. They isolate the parts that need lubrication from the output parts in the transmission components to prevent the lubricating oil from leaking. The representative form of oil seals is TC oil seals, which are double-lip oil seals with self-tightening springs that are completely covered with rubber. Generally speaking, oil seals often refer to TC skeleton oil seals. With the continuous development of society, more and more oil seals are used, but some oil seal locating rings have some defects when used. For example, the self-tightening spring inside the oil seal locating ring will deviate, causing oil leakage, thereby affecting the service life of the oil seal. When the traditional oil seal locating device is used on the rotating shaft, there will always be friction between the rotating shaft and the oil seal, which will lead to limited support effect of the positioning device and poor use effect. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a rotating shaft oil seal positioning device to solve the problem that when the oil seal positioning device of the prior art is used on a rotating shaft, friction will always be directly generated between the rotating shaft and the oil seal, which will lead to limited supporting effect of the positioning device and poor use effect.
[0004] In view of this, the utility model provides a rotating shaft oil seal positioning device, comprising an oil seal body, a self-tightening spring is arranged inside the oil seal body, and a plurality of supporting positioning mechanisms are arranged on one side of the self-tightening spring;
[0005] The supporting and positioning mechanism includes a spring member, a connecting plate and a supporting frame. An installation cavity is opened inside the oil seal body. One end of the spring member is fixedly mounted on the inner wall of the installation cavity, and the other end of the spring member is fixedly mounted on one end of the connecting plate. The supporting frame is fixedly mounted on the other end of the connecting plate, and the supporting frame is located on one side of the self-tightening spring.
[0006] Optionally, a plurality of the supporting and positioning mechanisms are evenly distributed inside the oil seal body.
[0007] Optionally, the support frame is an arc-shaped member with a semicircular cross-section.
[0008] Optionally, the spring component is made of copper-nickel alloy.
[0009] Optionally, a mounting groove is provided on one side of the oil seal body, and the self-tightening spring is clamped inside the mounting groove.
[0010] Optionally, a fixing ring is fixedly mounted on the inner wall of the oil seal body.
[0011] Optionally, a heat conducting member is fixedly mounted on one end of the fixing ring, a heat sink is fixedly mounted on one end of the heat conducting member, and one end of the heat sink extends into the interior of the mounting cavity.
[0012] It can be seen from the above technical solutions that the embodiments of the utility model have the following advantages:
[0013] 1. The utility model is a rotary shaft oil seal positioning device, which adopts a supporting positioning mechanism. When the rotary shaft rotates and rubs against the oil seal body, the temperature of the oil seal body and the internal installation cavity of the oil seal body will increase. By using a copper-nickel alloy to make a spring part, the spring part will deform when the temperature rises, so that the connecting plate can be pushed to move to one side, so that the support frame at one end of the connecting plate can support the self-tightening spring, avoiding the self-tightening spring from deflecting, thereby improving the use effect and service life of the oil seal.
[0014] The utility model discloses a rotating shaft oil seal positioning device, which adopts the design of heat conducting parts and heat sinks. With such a design, the heat conducting parts can conduct heat, thereby preventing the inner wall temperature of the oil seal body from being too high, and the heat sink can guide the heat to the inside of the installation cavity, thereby providing heat for the deformation of the spring part, making the deformation effect of the spring part better.
[0015] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.
[0023] A rotating shaft oil seal positioning device according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.
[0024] Example 1
[0025] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of a rotating shaft oil seal positioning device, comprising an oil seal body 1, a self-tightening spring 10 is arranged inside the oil seal body 1, and a plurality of supporting positioning mechanisms are arranged on one side of the self-tightening spring 10;
[0026] The supporting and positioning mechanism includes a spring member 6, a connecting plate 7 and a supporting frame 8. An installation cavity 5 is opened inside the oil seal body 1. One end of the spring member 6 is fixedly installed on the inner wall of the installation cavity 5, and the other end of the spring member 6 is fixedly installed on one end of the connecting plate 7. The supporting frame 8 is fixedly installed on the other end of the connecting plate 7. The supporting frame 8 is located on one side of the self-tightening spring 10. Several supporting and positioning mechanisms are evenly distributed inside the oil seal body 1. The spring member 6 is made of copper-nickel alloy, and the supporting frame 8 is an arc-shaped member with a semicircular cross-section.
[0027] It should be noted that, by providing a support frame 8 with a semicircular arc-shaped cross-section, the support frame 8 can better support the self-tightening spring 10. When the rotating shaft rotates and rubs against the oil seal body 1, the temperature inside the oil seal body 1 and the internal mounting cavity 5 of the oil seal body 1 will increase. By using a copper-nickel alloy to manufacture the spring member 6, the spring member 6 will be deformed when the temperature rises, thereby pushing the connecting plate 7 to move to one side, so that the support frame 8 at one end of the connecting plate 7 can support the self-tightening spring 10 to avoid the self-tightening spring 10 from deflecting, thereby improving the use effect and service life of the oil seal.
[0028] In some embodiments, Figure 2 As shown, a mounting groove 9 is provided on one side of the oil seal body 1 , and a self-tightening spring 10 is clamped inside the mounting groove 9 .
[0029] It should be noted that the self-tightening spring 10 can be clamped by providing the mounting groove 9 .
[0030] Example 2
[0031] In some embodiments, Figure 3As shown, a fixing ring 2 is fixedly mounted on the inner wall of the oil seal body 1 , a heat conducting member 3 is fixedly mounted on one end of the fixing ring 2 , a heat sink 4 is fixedly mounted on one end of the heat conducting member 3 , and one end of the heat sink 4 extends to the inside of the mounting cavity 5 .
[0032] It should be noted that, by providing the heat conducting member 3, when heat is generated by friction between the rotating shaft and the inner wall of the oil seal body 1, the heat conducting member 3 can conduct the heat, thereby preventing the inner wall temperature of the oil seal body 1 from being too high. By providing the heat sink 4, the heat can be guided to the inside of the mounting cavity 5, thereby providing heat for the deformation of the spring member 6, thereby making the deformation effect of the spring member 6 better.
[0033] Working principle: After the oil seal body 1 is installed, when the rotating shaft rotates and rubs against the oil seal body 1, the temperature inside the oil seal body 1 and the installation cavity 5 inside the oil seal body 1 will increase. By using copper-nickel alloy to make the spring part 6, the spring part 6 will be deformed when the temperature rises, so that the connecting plate 7 can be pushed to one side, so that the support frame 8 at one end of the connecting plate 7 can support the self-tightening spring 10 to avoid the self-tightening spring 10 from deflecting. By setting the heat conductor 3, when the friction between the rotating shaft and the inner wall of the oil seal body 1 generates heat, the heat conductor 3 can conduct the heat to avoid the inner wall temperature of the oil seal body 1 being too high. By setting the heat sink 4, the heat can be guided to the inside of the installation cavity 5, so as to provide heat for the deformation of the spring part 6 and make the deformation effect of the spring part 6 better.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
