The utility model relates to a permanent magnetic non-contact bearing supporting roller, which is used in the belt machine industry, comprising a shaft, a retaining ring, a labyrinth disk, a labyrinth ring, a bearing seat, a permanent magnetic bearing inner ring, a permanent magnetic bearing outer ring and a roller cover. The bearing seat is installed inside the roller, the outer ring of the permanent magnetic bearing is arranged in the bearing seat, the inner ring of the permanent magnetic bearing is arranged on the shaft, the labyrinth ring is arranged in the bearing seat, the labyrinth disk is arranged on the shaft, and the retainer ring is arranged on the shaft. The inner ring of the permanent magnetic bearing and the outer ring of the permanent magnetic bearing are matched with the cone surface, and the magnetic gap is arranged between the matching surfaces. The magnetic field between the inner ring of the permanent magnet bearing and the outer ring of the permanent magnetic bearing is the same as that of the magnetic pole, and the repulsion force between them is decomposed into radial repulsion force and axial repulsion force, thus realizing the radial and axial non contact positioning support of the roller skin. This new type of roller and roller bearings compared to traditional rotary friction free, small resistance, long service life, no strict demand for sealing, no lubricating oil and grease, no leakage, economy and environmental protection, and has the advantages of simple structure, maintenance free.
【技術實現步驟摘要】
一種永磁無接觸軸承托輥
本專利技術涉及一種永磁無接觸軸承托輥,主要用于實現降低托輥旋轉阻力,延長使用壽命,降低對密封的要求的目的。
技術介紹
現有的皮帶機托輥一般采用的是傳統軸承機械連接支撐,軸承存在著滾動摩擦,增加了托輥的旋轉阻力,且對密封要求嚴格,使用壽命低,一旦潤滑油或潤滑脂泄露,還會造成環境污染。
技術實現思路
為了實現托輥旋轉阻力小、對密封要求低、使用壽命長的目的,本專利技術提供了一種全新的永磁無接觸軸承托輥。本專利技術解決其技術問題所采用的方案是:一種永磁無接觸軸承托輥,由軸、擋圈、迷宮盤、迷宮環、軸承座、永磁軸承內圈、永磁軸承外圈及輥皮組成,永磁軸承外圈安裝在軸承座內,與軸承座過盈配合,永磁軸承內圈安裝在軸上,與軸過盈配合,永磁軸承內圈插入到永磁軸承外圈內。永磁軸承內圈與永磁軸承外圈均為強永磁材料制成。永磁軸承內圈為圓錐體,永磁軸承外圈內孔為錐孔,永磁軸承內圈插入到永磁軸承外圈的錐孔內并留有磁隙。永磁軸承內圈的圓錐外表面與永磁軸承外圈錐孔的內表面磁極性相同。本專利技術的有益效果是:托輥與傳統托輥相比旋轉阻力小,使用壽命長,對密封要求不嚴格,無潤滑油、潤滑脂,無泄漏,經濟環保,且構造簡單,免維修。附圖說明下面結合附圖和實施例對本專利技術進一步說明。圖1為本專利技術的整體結構示意圖。圖中:1.軸,2.擋圈,3.迷宮盤,4.迷宮環,5.軸承座,6.永磁軸承內圈,7.永磁軸承外圈,8.輥皮。具體實施方式在圖1中,一種永磁無接觸軸承托輥,由軸1、擋圈2、迷宮盤3、迷宮環4、軸承座5、永磁軸承內圈6、永磁軸承外圈7及輥皮8組成。其中軸承座5安裝在輥皮8內,與 ...
