Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically a belt idler roller with single-end grease injection. Background Technology

[0002] Idler rollers are key components of belt conveyors, playing a crucial role in numerous fields. They are mainly used in the chemical industry, automobile manufacturing, electronics manufacturing, machinery processing, food processing, logistics and warehousing, and agricultural product harvesting and processing. Idler rollers are the load-bearing components that enable belt conveyors to operate, and they are also the most numerous key components on belt conveyors.

[0003] Existing belt idlers generally lack lubrication points. If damaged, they must be replaced after a shutdown, making them almost disposable parts. If the idler bearings are not lubricated for a long time, the idler shaft will eventually overheat, causing the bearing to seize. The belt will dry-rub against the surface of the idler outer sleeve until the sleeve is worn through. In more serious cases, the dry-rubbing will cause high temperatures and sparks, creating danger or safety hazards.

[0004] Based on this, a single-end grease-injecting belt roller is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a single-end grease-injecting belt roller to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A single-end grease-injecting belt roller includes a main shaft, an outer bushing disposed on the outside of the main shaft, and a lubrication assembly disposed inside the main shaft;

[0008] The lubrication assembly includes a spindle connecting column. There are two spindle connecting columns, which are fixedly connected to both ends of the spindle. A filling port is opened through the spindle connecting column on one side of the spindle. A sealing plug is slidably connected to one end of the filling port. An inner groove is opened inside the spindle. Several dispersing ports are arrayed on one side of the spindle. One end of each dispersing port is connected to the inner groove.

[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0010] In one alternative: a sealing plug is slidably disposed at both ends of the spindle.

[0011] In one alternative: a bearing is provided on the outer side of each of the sealing plugs.

[0012] In one alternative: a limiting groove is provided on the inner side of both ends of the outer bushing, and each limiting groove is slidably connected to the adjacent bearing.

[0013] In one alternative: an inner contact layer is provided on the inner side of the outer bushing, a reinforcing layer is provided on the outer side of the inner contact layer, and an outer wear-resistant layer is provided on the outer side of the reinforcing layer.

[0014] In one alternative: the outer wear-resistant layer is made of carbon steel, and several anti-slip grooves are arrayed on the outer side of the outer wear-resistant layer.

[0015] In one alternative, the reinforcing layer is made of stainless steel.

[0016] In one alternative: the inner contact layer is made of carbon fiber reinforced material.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model, by setting a lubrication component, achieves double-end lubrication of the idler roller through single-end grease injection, avoiding the drawbacks of not actually adding lubricating oil or grease in the past. At the same time, it achieves the purpose of lubricating the bearings at both ends of the idler roller, which can maximize the service life of the idler roller bearings, reduce the frequency of maintenance and replacement, and thus effectively improve the use effect of this utility model and enhance the practicality of the idler roller.

[0019] 2. This utility model, through its detachable design, separates the outer bushing and the main shaft, so that when replacing them, it is not necessary to replace the whole thing; individual parts can be replaced, which effectively improves the performance and flexibility of this utility model.

[0020] 3. This utility model features an inner contact layer, etc. The outer wear-resistant layer is made of carbon steel and is galvanized or sprayed to improve its rust and corrosion resistance.
