Description

Technical Field

[0001] The utility model relates to the technical field of vibrators, in particular to a flange type vibrator with an oil level mirror. Background Art

[0002] The vibrator is a key component of the screening equipment. The bearings at both ends of the vibrator bear all the vibration impact forces generated when the vibrator is working. Therefore, using lubricating oil in the vibrator to lubricate and dissipate heat for the bearings is the key to ensure the long-term and effective operation of the vibrator.

[0003] The vibrator is a sealed structure as a whole, and the body is not transparent, so it is impossible to know the remaining amount of lubricating oil inside it, resulting in the inability to add lubricating oil in time, affecting the normal operation of the vibrator. In order to understand the liquid level of the internal lubricating oil, it is usually necessary to open the oil filling hole above the base of the thin oil vibrator for filling and observation, which is very troublesome. Generally, the principle of communicating vessels is used to install an oil level mirror on the outside of the vibrator to effectively observe the lubricating oil level inside the vibrator.

[0004] In the prior art, the oil level mirror and the vibrator are usually installed separately, and then the two are connected through an oil pipe. The installation process is cumbersome, and during the operation of the vibrator, the oil pipe is easily vibrated, causing damage to the oil circuit, resulting in the oil level mirror being unusable or even the vibrator leaking oil.

[0005] Therefore, the present application provides a flange-type vibrator with an oil level mirror to meet the needs. Utility Model Content

[0006] The purpose of this application is to provide a flange-type vibrator with an oil level mirror, which uses specially designed bolts to directly install the oil level mirror on the vibrator without the need for connection through an oil pipe, thereby improving the installation convenience and working stability of the oil level mirror.

[0030] Example 1: Reference Figure 1 and Figures 5 to 9 The flange-type vibrator with an oil level mirror shown in the figure comprises a vibrator body 1, in which a lubrication cavity 10 is provided, and the lubrication cavity 10 is used to inject lubricating oil;

[0031] The vibrator body 1 has symmetrical side wing blocks 11 on its left and right sides. The side wing blocks 11 have an upper through hole 12 and a lower through hole 13. The upper through hole 12 and the lower through hole 13 are both horizontally arranged and connected to the lubrication cavity 10. The upper through hole 12 is located above the lower through hole 13.

[0032] An oil level mirror 2 is provided on the end face of the outer side of the side wing block 11, and an oil box 20 is provided in the oil level mirror 2. The oil box 20 is used to observe the lubricating oil level. The oil box 20 is a hollow shell. The upper and lower parts of the oil box 20 are provided with through holes, and guide bolts 3 are inserted in the through holes. The ends of the upper through hole 12 and the lower through hole 13 are threadedly connected to the threaded section of the guide bolt 3.

[0033] A sealing section 31 is provided on the catheter bolt 3, and a cavity 30 is provided in the catheter bolt 3. The cavity 30 is arranged along the axis of the catheter bolt 3 and passes through the sealing section 31 and the threaded section. The opening of the cavity 30 is located at the end of the threaded section. The sealing section 31 passes through the through hole and seals the through hole. An oil hole 32 is provided on the sealing section 31. The oil hole 32 connects the cavity 30 with the inner cavity of the oil box 20. The cavity 30 in the upper catheter bolt 3 is connected to the upper through hole 12, and the cavity 30 in the lower catheter bolt 3 is connected to the lower through hole 13.

[0034] As an implementation method in this embodiment, in order to facilitate the assembly between the blocking section 31 and the perforation, as shown in FIG. Figures 7 to 9As shown, the outer diameter of the sealing section 31 is larger than the outer diameter of the threaded section, and an inward-concave annular arc groove is provided in the middle of the sealing section 31. The width of the annular arc groove is adapted to the inner cavity thickness of the oil box 20, and the oil hole 32 is located in the annular arc groove.

[0035] As an implementation method in this embodiment, in order to improve the sealing effect of the blocking section 31 on the perforation, as shown in FIG. Figure 8 As shown, the sealing section 31 is provided with a first sealing ring 6 and a second sealing ring 5. The first sealing ring 6 is used to seal the contact position between the through-hole near the bolt cap of the catheter bolt 3 and the sealing section 31. The second sealing ring 5 is used to seal the contact position between the sealing section 31 and the through-hole and the contact position between the threaded section and the flank block 11.

[0036] As an implementation method in this embodiment, in order to protect the oil box 20, as shown in FIG. Figures 5 to 8 As shown, the outer cover of the oil box 20 is provided with a cover shell 21, which protects the outer side of the oil box 20. The cover shell 21 is provided with an observation groove and a through groove. The position of the through groove and the through hole correspond to the size of the through hole. The conduit bolt 3 passes through the through groove and the through hole. The bolt cap of the conduit bolt 3 abuts against the cover shell 21, and the first sealing ring 6 is located between the cover shell 21 and the oil box 20.

[0037] Example 2: Reference Figure 2-9 A flange-type vibrator with an oil level mirror is shown. The difference between this embodiment and the first embodiment is that an oil level mirror 2 is provided on the front side of the side wing block 11, and the ends of the upper through hole 12 and the lower through hole 13 are equipped with sealing bolts 4. The front side of the side wing block 11 is provided with surface through holes 14, and there are two groups of surface through holes 14, which are respectively connected to the upper through hole 12 and the lower through hole 13, and the threaded section of the guide bolt 3 is threadedly connected to the surface through hole 14.

[0038] The working principle of the utility model is as follows: when the oil level mirror 2 is installed on the end face of the wing block 11 using the guide bolt 3, the specific method is that the blocking section 31 passes through the cover 21 and the oil box 20, and the threaded section is screwed into the upper through hole 12 and the lower through hole 13 respectively. Through the upper through hole 12, the lower through hole 13 and the cavity hole 30 and the oil hole 32 on the guide bolt 3, the inner cavity of the oil box 20 is connected with the lubrication cavity 10. Thus, by utilizing the communicating vessel principle, the lubricating oil level in the oil box 20 is the same as that in the lubrication cavity 10, so that the lubricating oil level in the lubrication cavity 10 can be observed. The first sealing ring 6 plays a sealing role between the cover 21 and the oil box 20, and the second sealing ring 5 plays a sealing role between the oil box 20 and the wing block 11 to prevent the lubricating oil from leaking out; using the guide bolt When the bolt 3 is used to install the oil level mirror 2 on the front side of the wing block 11, the difference from the end face installation is that the ends of the upper through hole 12 and the lower through hole 13 are sealed with a sealing bolt 4, and the threaded section of the guide bolt 3 is installed in the face through hole 14, thereby fixing the oil level mirror 2 on the front side of the wing block 11; the outer diameter of the blocking section 31 is designed to be larger than the outer diameter of the threaded section, which can enhance the force strength of the blocking section 31 so as to tighten the guide bolt 3 during installation. The arc-shaped annular groove on the blocking section 31 can improve the convenience of installing the blocking section 31 and the oil box 20. The wing blocks 11 are symmetrically arranged on both sides of the vibrator body 1 for installing the oil level mirror 2, which can improve the accuracy of observing the lubricating oil level and improve the practicality of the vibrator in different installation environments.
