The utility model provides a fine-tuning compensating mixing shaft for wear-resistant ring of an internal mixer, which comprises a shaft body. The middle part of the shaft body is provided with a stirring blade. The two ends of the stirring blade are provided with a sealing support part whose diameter is larger than the shaft body. The sealing support part is facing the end of the shaft body with an end groove, and the shaft body and density are arranged. The connecting part of the sealing support part is provided with a shoulder, and several positioning grooves are arranged on the outer cylindrical wall of the shoulder. The outer cylindrical wall of the shoulder is also provided with adjusting threads. The adjusting threads are rotated with wear-resisting rings. The wear-resisting rings are fitted with positioning grooves and fixed screws for adjusting the position of the wear-resisting rings in the last direction of the adjusting threads. . The utility model realizes the rotation angle of the wear-resistant ring on the shoulder by setting a positioning groove on the shoulder, thus realizing the adjustment of the axial position of the wear-resistant ring on the shoulder, thereby realizing the adjustment of the clearance between the wear-resistant ring and the outer ring of the bearing, and avoiding the mixing material entering the bearing.

一种密炼机耐磨环微调补偿搅拌轴
本技术涉及密炼机领域,具体涉及一种密炼机耐磨环微调补偿搅拌轴。
技术介绍
密炼机是用于橡胶、塑料和塑炼及各种胶料、塑料的混炼、在极短时间内将聚合物材料熔融,并促进胶化,色料及发泡剂在此加入混炼。而现有的密炼机包括密炼室及密炼轴,密炼轴的两端穿出密炼室,在大型密炼机中,其密炼轴往往尺寸较长直径较大,对其生产要求较高,导致其成产成本的增加,密炼轴在工作时由于其上方设有桨叶,因此会产生轴向推力导致密炼轴端部与轴承之间产生间隙,长久下来容易造成混炼材料通过轴部与轴承之间的间隙进入轴承内影响轴承寿命,因此现有的密炼轴往往在安装轴承的部位装有轴肩从而阻挡混炼材料,但是在实际使用中会出现磨损等情况造成混炼物进入轴承,因此可靠性较低。
技术实现思路
基于上述问题,本技术目的在于提供一种结构简单,具有轴向密封调节功能、且调节方便的密炼机耐磨环微调补偿搅拌轴。针对以上问题,提供了如下技术方案:一种密炼机耐磨环微调补偿搅拌轴,包括轴体,所述轴体中段设有搅拌叶,所述搅拌叶两端设有密封支撑部,所述密封支撑部直径大于轴体,所述密封支撑部朝向轴体端部的一面设有端面沟槽,所述轴体与密封支撑部相连处设有轴肩,所述轴肩外圆柱壁上均布开设有若干定位槽,所述轴肩外圆柱壁上还设有调节螺纹,所述调节螺纹上旋有耐磨环,所述耐磨环上设有与定位槽配合、用于调节耐磨环在调节螺纹上周向位置的紧定螺钉。上述结构中,通过在轴肩上设置定位槽,从而配合紧定螺钉实现耐磨环在轴肩上的旋合角度,从而实现耐磨环在轴肩上的轴向位置的调节从而实现调节与轴承外圈之间的间隙,避免混炼材料进入轴承内,端面沟槽可 ...
