Description

Technical Field

[0001] This utility model relates to the field of vibrator equipment technology, and in particular to a low-oil-level, thin-oil-lubricated vibrator that is easy to install. Background Technology

[0002] The thin oil vibrator is a mechanical device that uses the rotation of an eccentric block to generate directional vibration force. A motor drives the eccentric block to produce centrifugal force, creating horizontal or vertical vibration, used in applications such as soil reinforcement and material screening. The thin oil vibrator uses an oil-dispensing blade design for lubrication. The blades are symmetrical and of uniform length in an arc shape, for example, by fixing fan-shaped or strip-shaped thin blades of the same length to a connecting plate with bolts to enhance the coverage area during centrifugal oil dispensing. However, to improve sealing, the vibrator housing is open at both ends, which limits the structural types of the oil-dispensing blades. Furthermore, due to limited space in the bearing chamber, the design length of the oil-dispensing blades is too short, resulting in a small oil level difference range in the oil reservoir and insufficient lubrication at the bottom. Customers experience bearing damage or seizure during use due to changes in equipment angle or low oil levels. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a low-oil-level thin-oil lubricated vibrator that is easy to install, has a simple structure, is easy to install, and can still maintain a good lubrication effect when the lubricating oil level is low.

[0004] The solution is a low-oil-level thin-oil lubricated vibrator that is easy to install, comprising a main shaft and a housing. Both ends of the housing are provided with open bearing holes. The main shaft passes through the two bearing holes and is mounted on the housing via two bearings. An oil slinger is installed on the main shaft inside the housing. The oil slinger includes an annular mounting sleeve. A high-oil-level blade and a low-oil-level blade are fixed on the mounting sleeve. The high-oil-level blade and the low-oil-level blade are located on opposite sides of the mounting sleeve. The low-oil-level blade is longer than the high-oil-level blade. Both ends of the housing are provided with end caps that close the housing cavity. Eccentric block assemblies are installed at both ends of the main shaft.

[0005] Preferably, the high oil level blade is perpendicular to the low oil level blade and the high oil level blade is perpendicular to the main shaft.

[0006] Preferably, the centerline of the high oil level blade is collinear with the centerline of the low oil level blade.

[0007] Preferably, the housing has a chamber structure that is smaller on the inside and larger on the outside, and the housing chamber is symmetrical about the center plane of the low oil level blade.

[0008] Preferably, the end of the low oil level blade is provided with at least one groove.

[0009] Preferably, the low oil level blade and the eccentric block assembly are oriented in the same direction.

[0010] Preferably, at least one oil level sight glass is installed on the housing.

[0011] Preferably, a first protective cover is provided on one side of the housing, and a second protective cover is installed on the other side. The vibrator is installed on the screening equipment, the first protective cover is located near the screening equipment, and the eccentric block assembly is located inside the first or second protective cover on the same side.

[0012] The beneficial effects of this invention are as follows: The vibrator housing is integrally molded, increasing the oil storage capacity without affecting the bearing size installation; the oil slinger can be installed into the housing from both sides, making installation convenient. Due to the eccentric principle of longer blades at low oil levels and shorter blades at high oil levels, the oil slinger blades can carry up lubricating oil from the bottom of the vibrator without being affected by installation dimensions, increasing the amount of lubricating oil entering the bearing and improving the lubrication effect, ensuring good lubrication even when the lubricating oil level is low.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 5A low-oil-level thin-oil lubricated vibrator that is easy to install is provided, comprising a main shaft 1 and a housing 2. Both ends of the housing 2 are provided with open bearing holes. The main shaft 1 passes through the two bearing holes and is mounted on the housing 2 by two bearings 7. The housing 2 is characterized by being hollow and open at both ends, and being integrally formed. An oil-throwing component 3 is installed on the main shaft 1 and located inside the housing 2. The oil-throwing component agitates and lifts the lubricating oil to lubricate the two bearings 7 between the main shaft 1 and the housing 2. The oil-throwing component 3 includes an annular mounting sleeve 301. A high oil level blade 302 and a low oil level blade 303 are fixed on the mounting sleeve 301. The high oil level blade 302 and the low oil level blade 303 are located on opposite sides of the mounting sleeve 301. The low oil level blade 303 is longer than the high oil level blade 302. When the low oil level blade 303 moves to the bottom of the vibrator, it lifts the lubricating oil, which can drive the lower oil level in the vibrator and stir up the lubricating oil at the bottom of the vibrator housing. Then, the high oil level blade 302 can be agitated by a portion of the lubricating oil driven by the low oil level blade 303, which then enters the bearing 7 to lubricate the bearing 7. The low-oil-level blade 303 and the high-oil-level blade 302 have different lengths, which allows for better removal of lubricating oil from the bottom of the vibrator housing 2 within a limited overall length. When installing the oil slinger 3, first insert one end of the high-oil-level blade 302 into the housing 2 through the bearing hole, then insert the low-oil-level blade 303 into the housing 2. Next, install the main shaft 1 and the oil slinger 3 via a transmission key. Then, install the main shaft 1 onto the bearing hole of the housing 2 via the bearing 7. Finally, install the seal and end cap 4. The housing 2 has end caps 4 at both ends to seal the housing 2 chamber, and eccentric block assemblies 5 are installed at both ends of the main shaft 1.

[0020] The high oil level blade 302 is perpendicular to the low oil level blade 303, and the high oil level blade 302 is perpendicular to the main shaft 1. After the lubricating oil in the housing 2 is carried up by the oil slinger 3, some of the lubricating oil collides with the inner wall of the housing 2, and some of it impacts the low oil level blade 303 and the high oil level blade 302, and is then impacted onto the bearing 7. The vertical arrangement of the low oil level blade 303 and the high oil level blade 302, after the high-speed rotation of the oil slinger 3, allows the lubricating oil to be bounced up from different angles by the low oil level pawl and the high oil level pawl, and then enter the bearing 7, which can significantly increase the amount of lubricating oil entering the bearing 7. The high oil level blade 302 is perpendicular to the main shaft 1. Because it has a deeper oil lubrication depth, this setting can reduce its lubrication contact area and the impact surface with the lubricating oil. It can both agitate the lubricating oil at the bottom and cooperate with the vertical high oil level pawl to better impact the lubricating oil into the bearing 7, and reduce the contact surface with the lubricating oil to prevent the lubricating oil from overheating.

[0021] The centerline of the high oil level blade 302 is collinear with the centerline of the low oil level blade 303. This arrangement allows the oil-dispensing assembly to be better installed in the middle of the housing 2, and to provide better and more uniform lubrication to the bearings 7 installed on both sides of the housing 2.

[0022] The chamber of the housing 2 has a structure with a smaller inner side and a larger outer side, and the chamber of the housing 2 is symmetrical about the center plane of the low oil level blade 303. This allows for the holding of more lubricating oil while ensuring the installation dimensions of the bearing 7 and reducing the overall size.

[0023] The end of the low oil level blade 303 is provided with at least one groove 304. The groove 304 is provided on the side of the low oil level blade 303 away from the mounting sleeve 301, so that its end presents multiple tooth-like structures. This design of the low oil level blade can better carry the lubricating oil at the bottom of the housing 2, increase the contact surface that can carry the lubricating oil, increase the amount of lubricating oil entering the bearing 7, and improve the lubrication effect of the vibrator.

[0024] The low oil level blade 303 and the eccentric block assembly 5 are oriented in the same direction. The asymmetrical arrangement of the low oil level blade 303 and the high oil level blade, along with the arrangement of the low oil level pawl, allows the polarization generated by the low oil level blade 303 to be superimposed with the polarization effect generated by the eccentric block assembly 5, thereby improving the polarization effect.

[0025] At least one oil level sight 6 is installed on the housing 2. The oil level sight 6 is used to observe the level of lubricating oil inside the housing 2.

[0026] The housing has a first protective cover 7 on one side and a second protective cover 8 on the other side. The vibrator is installed on the screening equipment, with the first protective cover 7 positioned close to the screening equipment. The eccentric block assembly is located inside either the first protective cover 7 or the second protective cover 8 on the same side. Both the first protective cover 7 and the second protective cover 8 are bolted to the housing, providing safety protection and preventing dust from entering the housing during the high-speed operation of the thin oil vibrator, while also improving the aesthetics of the equipment.

[0027] The second protective cover 8 adopts a box-shaped structure with an opening at one end facing the shell. The second protective cover 8 includes a second protective cover shell that is symmetrically arranged at the top and bottom. The two second protective cover shells are connected by bolts. The second protective cover 8 is composed of two symmetrical upper and lower parts, and its cross-section is an octagonal structure.

[0028] The first protective cover 7 adopts a box-shaped structure with one end open to the housing, and its cross-section is an octagonal structure. The bottom of the first protective cover 7 is provided with an opening, and an installation plate 701 is detachably installed at the opening. The bottom of the first protective cover 7 is provided with a protective plate 702 located above the main shaft.

[0029] The beneficial effects of this utility model are as follows: The vibrator housing is integrally molded, increasing the oil storage capacity without affecting the bearing size installation; the oil slinger can be installed into the housing from both sides, making installation convenient; compared with the traditional pipeline-type independent oil level mirror, it saves more installation space. The short oil passage distance effectively avoids problems such as slow oil flow and inaccurate oil level display caused by the viscosity of the lubricating oil when adding lubricating oil, compared with the traditional pipeline-type independent oil level mirror. The vibrator operating temperature can be promptly transmitted to the oil level mirror, and the oil return speed is relatively fast. The oil level mirror body adopts a fully transparent design, allowing for all-round observation of the vibrator's oil storage status; the oil slinger blades, due to the eccentric principle of longer blades at low oil levels and shorter blades at high oil levels, can carry up the lubricating oil at the bottom of the vibrator without being affected by the installation size, increasing the amount of lubricating oil entering the bearing and improving the lubrication effect, ensuring good lubrication even when the lubricating oil level is low.

[0030] The embodiments described above are not intended to limit the scope of this utility model. Any modifications and improvements made to the technical solutions of this utility model by those skilled in the art without departing from the design concept of this utility model should be included within the protection scope defined by the claims of this utility model.
