The utility model discloses a bearing device for a conveyor middle suspension, which includes a bearing seat mounted on a conveyor case and a bearing installed in a bearing seat. The screw shaft of the conveyor is supported by the inner ring of the bearing. The rear cover is mounted on the rear side of the bearing seat of the material transmission direction, and a O type sealing ring is provided in the end cover. The characteristics are: the front side of the bearing seat is equipped with a labyrinth seal on the front side of the bearing seat. The inner ring of the labyrinth sealing ring is fitted to the spiral shaft. The front side of the bearing seat is equipped with grooves, and the ring seal teeth of the labyrinth seal ring are fitted in the groove. By setting the labyrinth sealing ring on the front side of the bearing seat with the direction of the material transmission, the utility model makes use of the better sealing effect of the labyrinth seal ring to prevent the dust from entering the bearing seat to wear the bearing, ensuring the normal work of the bearing and effectively improving the overall sealing effect of the conveyer suspension bearing.

输送机中间悬挂轴承装置
本技术涉及一种输送机中间悬挂轴承装置。
技术介绍
长距离输送物料的输送机,中间通常设置有悬挂轴承装置,以确保输送轴的平稳转动。由于输送机传送的多为颗粒或粉尘类物料,传输过程中很容易进入悬挂轴承座内,对轴承产生不利影响,造成轴承磨损,虽然轴承座内设置了密封圈,但对于正对物料传送方向一侧的轴承来说,密封效果依然不佳,正面冲击的灰尘还是会渗透进入轴承座内而影响轴承正常运转。
技术实现思路
本技术要解决的技术问题是:克服现有技术中之不足,提供一种能有效提高密封效果、确保轴承正常工作的输送机中间悬挂轴承装置。本技术解决其技术问题所采用的技术方案是:一种输送机中间悬挂轴承装置,包括可悬挂安装在输送机机壳上的轴承座、安装在轴承座内的轴承,输送机的螺旋轴支撑于轴承内圈,背向物料传输方向的轴承座后侧面安装有端盖,端盖内设有O型密封圈,正对物料传输方向的轴承座前侧面设有迷宫密封圈,迷宫密封圈的内圈贴合在螺旋轴上,轴承座前侧面上设有沟槽,迷宫密封圈的环形密封齿配合安装在沟槽内。本技术的有益效果是:本技术通过在正对物料传送方向的轴承座前侧面设置迷宫密封圈,利用迷宫密封圈较 ...
