Abstract

塑钢托辊涉及带式输送机上的部件,它包括有内轴及两端的轴承,轴承外圆面有外管和外侧面有挡盖。主要是轴承的内外套间有两个对接的保持架,内套外圆面和外套内圆面上有两道对应的滚珠槽,槽内各放有若干滚珠。该托辊各部件大多用PA工程塑料制作。它在灰尘较大时不粘灰尘、不被卡死,具有耐摩擦、耐腐蚀、重量轻、噪音低、起动功率小、寿命长等优点。经试验,使用寿命是普通托辊2.5—3.5倍。

Description

塑钢托辊
本实用新型涉及带式输送机中的部件。
目前带式输送机在厂矿输送材料中运用较为广泛,关键部件托辊的好坏直接影响到该机的运行质量。现有的托辊大多是用钢制轴承作主要部件,该托辊的最大不足是怕酸碱、不耐腐,轴承内的黄油遇尘后会在短期内被粘结,甚至卡死不运作。维修或更换轴承又影响了生产。最近出现的某些塑钢托辊,虽然克服了怕酸碱的缺陷,但由于设计不合理,运作经常卡死或更换频繁,在大范围内未得到推广。
本实用新型的目的是设计一种耐酸碱、耐摩擦、重量轻,采用PA工程塑料注塑成型,使用中不粘灰尘,运作寿命长的塑钢托辊。
上述目的是这样实现的:塑钢托辊包括有内轴和两端设置的轴承,两套轴承外圆面有外管和外侧面有挡盖,主要是轴承包括内套和它外圆有两个对接的保持架,保持架外圆有外套,内套外圆面和外套内圆面各有两道相对应的滚珠槽,滚珠槽内放置有若干滚珠,在保持架上开有与滚珠数目相同的滚珠孔。内套外端面突出一段端轴放置于输送机支架上。
该托辊除内轴和滚珠外全部采用PA工程塑料制作,两外端面设置有挡盖,因此它耐酸碱、抗腐蚀,同时利用PA材料的自润性能,制作时不用注油可在灰尘较大场地使用不粘灰尘、不被卡死。该托辊具有耐磨擦、耐腐蚀、重量轻、噪音低、起动功率小、寿命长等优点。经试验,使用寿命是普通托辊的2.5-3.5倍,而成本却基本相同。
附图为结构示意图。
实施例:附图中为半剖,并仅示出一个轴承,该托辊包托有内轴1及两端设置的轴承,两轴承外表面包有外管2,轴承外表面设置两个挡盖,即内挡盖3和外挡盖4。主要是轴承有内轴1外园套有的内套5,内套5外圆有两圆形对接的保持架6,保持架6外圆有外套7,内套5的外圆面和外套7的内圆面各有两道相对应的滚珠槽8,滚珠槽8内各放有若干滚珠9,本例各设置6个滚珠。每个保持架6上有与滚珠数目相同的滚珠孔,以保持滚珠间的距离。内挡盖3卡于外套7外侧面定位,外挡盖4卡于内挡盖3上定位,内外挡盖有效防止了灰尘进入轴承内,内套5外端面突出一段以便放置于输送机支架上,传输带放置于外管2表面,该托辊除内轴和滚珠外均可用塑料制作。
