Suction nozzle roller sealing device
The invention discloses a suction nozzle roller sealing device, and relates to the field of cleaning and sweeping vehicle suction nozzle roller sealing, the suction nozzle roller sealing device comprises a roller support, a tire, a wheel core, a bearing, a spacer bush, a roller shaft, a locking nut, an oil cup and sealing covers, the wheel core comprises a rim, a hub and spokes, and the sealing covers are arranged on the two sides of the hub. Non-contact labyrinth sealing is formed between the annular groove formed in the inner ring of the sealing cover and the outer ring of the hub, so that rotating heating is avoided. By arranging the V-shaped groove for flowing out, muddy water is prevented from entering the inner cavity of the sealing cover, external gravel and muddy water are effectively prevented from entering the bearing, and abnormal abrasion of the bearing is avoided.
本发明公开了一种吸嘴滚轮密封装置，涉及洗扫车吸嘴滚轮密封领域，本发明包括滚轮支架、轮胎、轮芯、轴承、隔套、滚轮轴、锁紧螺母、油杯以及密封盖，所述轮芯包括轮辋、轮毂、轮辐，轮毂的两侧设有密封盖。本发明通过设置通过密封盖上内圈上设置的环形沟槽与轮毂外圈之间形成无接触迷宫密封，避免旋转发热。通过设置V型沟槽流出，阻止了泥水进入密封盖内腔，有效防止外界砂石、泥水进入轴承，避免轴承异常磨损。
