Abstract
Description
Technical Field
[0001] This utility model relates to a thin oil lubrication structure for the bearing of a vibrating screen vibrator, belonging to the field of vibrating screen technology. Background Technology
[0002] A vibrating screen is a screening machine used to classify various materials into granular forms. It mainly consists of a screen box, a vibrator, a spring support device, and a drive unit. Its working principle is that an electric motor drives an eccentric shaft inside the vibrator. The eccentric part of the eccentric shaft rotates around a fixed axis, generating centrifugal force. The rotation of the eccentric shaft causes the screen box to perform a directional jumping motion. During this motion, materials smaller than the screen aperture fall through the screen holes to the lower layer, becoming undersize material. Materials larger than the screen aperture are discharged from the discharge end after continuous jumping motion, thus completing the screening process. Based on the structural characteristics and working principle of a circular vibrating screen, the screen surface is generally installed at an angle.
[0003] Publication number CN214742798U mentions a thin oil lubrication structure for the bearings of a vibrating screen. By using thin oil lubrication, the bearings only need to be lubricated once, eliminating the need for repeated lubrication. This effectively avoids bearing damage caused by insufficient lubrication due to inadequate manual lubrication or blocked oil circulation, ensuring the normal operation of the bearings. However, during the process of introducing lubricating oil, dust or metal particles may enter the oil groove of the vibrating screen bearing. As the lubricating oil is used, these particles will enter the bearing, affecting the performance of the lubricating oil. Furthermore, the existing technology has a loose connection between the oil groove and the filter screen, which makes the filter screen prone to falling off and being contaminated by the external environment. If the connection is too tight, it is difficult to put the filter screen into the oil groove. There is an urgent need for a thin oil lubrication structure for the bearings of a vibrating screen to solve the above-mentioned problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a thin oil lubrication structure for the bearing of a vibrating screen vibrator, thereby solving the problems mentioned in the background art. This utility model is highly practical. By using a magnetic suction structure to connect the magnetic suction tube and the support base, the magnetic suction tube can be easily installed in the support base, while the pressure strip fixes the filter tube in the support base. By installing the filter tube in the support base, the filter tube can filter the lubricating oil, preventing the magnetic suction tube from being contaminated by external factors.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a thin oil lubrication structure for a vibrating screen vibrator bearing, comprising a bearing housing, a bearing body, and a rotating shaft, wherein a mating seat is fixedly connected to the right end of the bearing housing by bolts, a support seat is fixedly connected to the upper end of the bearing housing, a threaded fixing head is fixedly connected to the threaded surface of the upper end of the support seat, and four pressure strips are fixedly connected to the lower end of the threaded fixing head.

Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] Please see Figures 1-7This utility model provides a technical solution: a thin oil lubrication structure for a vibrating screen vibrator bearing, including a bearing seat 2, a bearing body 15, and a rotating shaft 5. A mating seat 1 is bolted to the right end of the bearing seat 2. A support seat 4 is fixedly connected to the upper end of the bearing seat 2. A threaded fixing head 3 is fixedly connected to the threaded surface of the upper end of the support seat 4. Four pressure strips 6 are fixedly connected to the lower end of the threaded fixing head 3. A magnetic suction tube 8 is installed inside the support seat 4. A filter tube 9 is fixedly connected to the lower end of the magnetic suction tube 8. A viscometer 10 is fixedly connected to the lower end of the filter tube 9. An oil inlet groove 11 is opened inside the bearing seat 2. The lower inner wall is provided with a first oil guide groove 12, and multiple oil passage grooves 14 are provided in the bearing seat 2. A second oil guide groove 13 is provided in the bearing seat 2. The first oil guide groove 12, the oil passage grooves 14 and the second oil guide groove 13 are interconnected. This design solves the problem that in the original device, dust or metal particles will enter the oil groove of the vibrator bearing during the process of introducing lubricating oil. As the lubricating oil is used, they will enter the bearing, thereby affecting the performance of the lubricating oil. In addition, the existing technology has a loose connection structure between the oil groove and the filter screen, which makes the filter screen easy to fall off and be contaminated by the external environment. The connection is too tight, making it difficult to put the filter screen into the oil groove.
[0024] In the first embodiment of this utility model: the surface of the threaded fixing head 3 is provided with an anti-slip layer. The viscometer 10 is slidably connected to the oil inlet groove 11 and the first oil guide groove 12. The anti-slip layer on the surface of the threaded fixing head 3 can increase the friction between the threaded fixing head 3 and the fingers, preventing slippage during the rotation of the threaded fixing head 3. The viscometer 10 can detect the viscosity of the lubricating oil inside the first oil guide groove 12 and the oil passage groove 14 by penetrating deep into them. The support base 4 has a placement groove 17, and a sealing gasket 7 is fixedly connected in the placement groove 17. The sealing gasket 7 in the placement groove 17 can reduce the collision caused by the magnetic suction tube 8 and the support base 4 when they are connected, thereby increasing the service life of the magnetic suction tube 8. A pull tab 16 is fixedly connected to the upper end of the magnetic suction tube 8. The filter tube 9 is slidably connected to the support base 4. The pull tab 16 installed on the upper end of the magnetic suction tube 8 allows workers to hook the pull tab 16 to remove the filter tube 9 for replacement or cleaning. The filter tube 9 slides in the support base 4, allowing the filtered lubricating oil to be guided into the bearing housing 2 through the support base 4, and then flow separately through the second oil guide groove 13. The lower ends of the four pressure strips 6 are all provided with rubber layers. The second oil guide groove 13 is connected to the connecting surface of the bearing body 15 and the rotating shaft 5. The rubber layer at the bottom of the pressure strip 6 can separate the pressure strip 6 and the magnetic suction tube 8, preventing the pressure strip 6 from causing squeezing marks on the magnetic suction tube 8. When lubricating oil is introduced into the oil inlet groove 11, the lubricating oil will enter the bearing body 15 through the second oil guide groove 13 and the oil passage groove 14, thereby achieving the effect of lubricating the bearing body 15. The rotating shaft 5 is fixedly connected inside the rolling sleeve of the bearing body 15. The bearing body 15 is fixedly connected between the bearing seat 2 and the mating seat 1. By fixing the rotating shaft 5 inside the rolling sleeve of the bearing body 15, the rotating shaft 5 can rotate inside the bearing body 15. The bearing body 15 is installed between the bearing seat 2 and the mating seat 1. The bearing seat 2 can support and protect the bearing body 15. The oil groove can increase the lubrication effect of the bearing body 15.
[0025] As a second embodiment of this utility model: First, unscrew the threaded fixing head 3, then introduce the lubricating oil into the magnetic suction tube 8. After the lubricating oil is filtered through the filter tube 9, it enters the first oil guide groove 12, and then spreads into the second oil guide groove 13 and immerses into the bearing body 15. After the lubricating oil is introduced, when the bearing has been running for a long time, the worker can unscrew the threaded fixing head 3, hook the pull tab 16 and take out the filter tube 9. The viscosity in the oil passage groove 14 can be judged by observing the color at the bottom of the viscometer 10. After the lubricating oil is treated, the magnetic suction tube 8 can be placed in the circular groove of the support base 4. The magnetic suction tube 8 is attracted to the support base 4. By screwing the threaded fixing head 3 onto the surface of the support base 4, and at the same time pressing the pressure strip 6, the magnetic suction tube 8 is fixed in the support base 4, thereby achieving the installation of the filter tube 9.
