AI Technical Summary
The existing bearing lubrication structure of grain and oil conveying equipment cannot completely clean up waste lubricating oil, which leads to accelerated wear and requires shutdown for lubrication maintenance, thus affecting equipment efficiency.
A small-hole structure including a bearing housing, a ring, and an arc-shaped groove is designed to achieve thorough cleaning and replacement of lubricating oil through the small hole and oil inlet. A removable semi-circular plate and a dustproof end cap are used to allow lubricating oil to be changed while the equipment is running.
This technology enables the complete cleaning and replacement of old lubricating oil with new lubricating oil without shutting down the machine, thereby improving bearing lubrication quality, extending bearing life, and increasing equipment operating efficiency.

Description
TECHNICAL FIELD
[0001] The utility model relates to conveying equipment lubricating structure technical field, especially a kind of lubricating structure of grain and oil conveying equipment. BACKGROUND
[0002] Grain and oil conveying equipment has quite high requirement to the lubrication of bearing, otherwise equipment failure rate and loss rate will obviously rise, so regular lubrication and oiling are carried out to bearing. In prior art, for example, a bearing lubricating mechanism disclosed in patent CN201731050U, a lubricating mechanism of bearing for pump disclosed in CN218717671U, a bearing lubricating mechanism and self-lubricating double-roller double-crushing machine device disclosed in CN221619560U, self-lubricating mechanism is mostly used, and dustproof or a small amount of oil storage is also increased in bearing end cover, etc., during regular inspection, only new lubricating oil or lubricating grease is extruded inward at bearing, but the original lubricating material in the interior cannot be completely cleaned, especially the waste chip generated by wear in original lubricating oil, which can accelerate the wear of ball bearing, even cause bearing failure, increase equipment power loss, which should be paid attention to, but unfortunately, the existing lubricating structure or system does not have the design of cleaning waste oil. In addition, the existing lubricating system generally needs to be stopped for maintenance or lubrication, which seriously affects the efficiency of grain conveying.
[0003] The present application provides a kind of lubricating structure of grain and oil conveying equipment to solve the above problems. UTILITY MODEL CONTENT
[0004] In view of the above situation, to overcome the defects of prior art, the utility model provides a kind of lubricating structure of grain and oil conveying equipment, which effectively solves the problem that the existing bearing lubricating structure cannot completely clean the original lubricating oil and needs to be stopped for maintenance and lubrication.
[0005] The technical solution is that, including bearing seat, bearing, main shaft, the bearing seat includes base, the base is fixed with annular ring, the bearing is in annular ring cavity, the outer steel ring of bearing is tightly attached to the inner wall of annular ring;Arc-shaped groove is arranged on the inner wall of annular ring cavity, small holes are arranged on the annular ring and communicated with the groove, oil inlet is formed on the outer steel ring of bearing;Lubricating oil can enter the groove through the small hole, and then enter the interior of bearing through the oil inlet.
[0006] Preferably, the annular ring is composed of two upper and lower opposing and detachable semicircular plates, and the groove and the small hole are arranged on each semicircular plate.
[0007] Preferably, the dustproof end cover is buckled on the bearing seat.
[0008] Preferably, the plug is arranged on the small hole to block the small hole.
[0009] The utility model discloses a clever structure, through the necessary modification to the bearing installation structure of the prior art, realize in the first old lubricating oil of the thorough cleaning of the patrol and inspection, pump into new lubricating oil again, so can greatly improve the lubrication quality of bearing, also can complete the replacement of lubricating paste under the condition of equipment not stopping, benefit prolonging the service life of bearing. BRIEF DESCRIPTION OF DRAWINGS
[0010] Fig. 1 It is the front view of the utility model.
[0011] Fig. 2 It is the side view of the utility model. DETAILED DESCRIPTION
[0012] The specific embodiment of the utility model is further explained in detail below in combination with the drawings.
[0013] By Figs. 1-2 Give, the utility model includes bearing 2 seat 1, bearing 2, main shaft 3, bearing 2 seat 1 includes base 4, and the circular ring 5 is fixed on base 4, and the bearing 2 is in the cavity of circular ring 5, and the outer steel ring 6 of bearing 2 is tightly attached with the inner wall of circular ring 5;The recess 7 of arc is arranged on the inner wall of the cavity of circular ring 5, and the small hole 8 that communicates with recess 7 is arranged on circular ring 5, and the oil inlet 9 is set up on the outer steel ring 6 of bearing 2;Lubricating oil can enter recess 7 through small hole 8, and then enter the inside of bearing 2 through oil inlet 9.
[0014] In order to facilitate the installation of bearing 2, the circular ring 5 is composed of two upper and lower opposite and detachable semicircular plates, and each semicircular plate is provided with recess 7 and small hole 8.
[0015] In order to prevent dust, the bearing 2 seat 1 is buckled with a dustproof end cover.
[0016] In order to prevent the leakage of lubricating paste during use, the small hole 8 is provided with a plug to block the small hole 8.
[0017] It is worth noting that in grain conveying, the dustproof pressure of equipment is very great, so generally bearing 2 with sealing ring is used, and the sealing level of sealing ring can only prevent the rapid leakage of lubricating paste in bearing 2, and cannot prevent the leakage of liquid or gas, so the scheme uses special cleaning liquid to clean the original old lubricating paste first, and then pumps new lubricating paste, so that the bearing 2 can be kept in good working condition for a long time.
[0018] When the bearing 2 lubricating paste needs to be replaced, it can be operated without stopping, specifically, the plug on the small hole 8 is removed first, then the cleaning liquid is pumped into the small hole 8 by using a liquid pump, the cleaning liquid sequentially passes through the small hole 8, the groove 7, the oil inlet 9, and finally enters the inside of the bearing 2, the original lubricating paste is diluted or dissolved by the cleaning liquid, then the cleaning liquid carrying the original waste lubricating paste in the bearing 2 leaks out through the end of the bearing 2, since the bearing 2 rotates with the main shaft 3 during the process, the lubricating paste in the bearing 2 is cleaned thoroughly; then, the new lubricating paste passes through the small hole 8, the groove 7, the oil hole, and finally enters the inside of the bearing 2, realizing the complete replacement of the lubricating paste in the bearing 2.
[0019] The utility model discloses clever structure, through to the necessary modification of existing bearing 2 installation structure, realize in the first old lubricating oil of patrol and examine thoroughly clean, pump in new lubricating oil again, can improve the lubrication quality of bearing 2 greatly, also can complete the replacement of lubricating paste under the condition that equipment does not stop, benefit prolongs the service life of bearing 2.
