The utility model discloses a roller structure of a particle machine, including from outside to inside are orderly sheathed outside the gland, roller bearing and the eccentric shaft, the outer cover and roller bearings at both ends of the end cover within the gland, the eccentric shaft through the inner gland, four roller bearings have side by side, into the the oil groove is arranged between the four roller bearing, the eccentric shaft is provided with two oil and gas into the oil tank is communicated with the injection tube, one of the main oil and gas injection pipe, the other a spare, its function is through the oil and gas injection pipe to the roller bearing grease makes the eccentric shaft bearing and roller lubrication completely the shaft, the eccentric shaft running through the continuous oil and gas injection tube into the compressed air, which makes the pressure roller structure produce a positive pressure inside to avoid entering the outside dust, and take the heat to the cooling effect, prolong the service life.
【技术实现步骤摘要】
一种颗粒机的压辊结构
本技术涉一种颗粒机,特别涉及一种颗粒机的压辊结构。
技术介绍
一般现有的生物质燃料颗粒机上所用的压辊,轴承直接内置在压辊内,而这种结构工作时,由于压辊与物料之间的摩擦,使得压辊的受力不均,容易发生摆动问题,而且产生较大的热量,热量会直接传递给轴承,因此轴承工作时温度会达到130-150℃,而且轴承在工作时对灰尘的洁净度要求也很高,灰尘一旦进入则对轴承造成一定程度的磨损,容易使压辊轴承损坏,并会因此增加润滑油的损耗量,致使轴承更换频繁,原料耗费严重等问题。
技术实现思路
为了克服现有技术的不足,本技术提供一种结构简单,保护粉碎机机壳内壁且易于更换的耐磨板。本技术解决其技术问题所采用的技术方案是:一种颗粒机的压辊结构,包括由外向内依次套接的外压盖、滚子轴承和偏心轴,所述外压盖和滚子轴承的两端端面上盖合有内压盖,所述偏心轴贯穿所述内压盖,所述滚子轴承有并排的四个,四个所述滚子轴承之间设置有进油槽,所述偏心轴设置有与所述进油槽连通的两个油气注入管。所述偏心轴的两端分别设置有卡簧,四个所述滚子轴承被夹持在两个所述卡簧之间。所述内压盖设置有固定螺栓,所述外压 ...
