The invention discloses a multi-lip oil packaging device, which comprises a rubber sealing ring, a static sealing surface is arranged along the axial extension of the periphery of the rubber sealing ring, a metal skeleton with a cross-section of zigzag is embedded between the rubber sealing ring and the static sealing surface, and a dynamic sealing component is arranged inside the rubber sealing ring, the dynamic sealing component comprises a main seal. The outer ring of the main seal lip and the auxiliary seal lip are all provided with ring grooves, and the ring grooves are provided with springs; the auxiliary seal lip lip mouth is semi-circular structure, and the main seal lip comprises the first main seal lip and the second main seal lip; the first main seal lip, the second main seal lip and the auxiliary seal lip lip mouth are respectively arranged. It has shallow twill and forms an oil return line. The oil seal device provided by the invention can reduce friction and prevent lip deformation by semi-circle design of the sub-seal lip, and can form pump effect at the lip mouth when the shaft works, so that the oil pump flowing to the air side of the oil seal can return to the oil side of the oil seal and reduce temperature rise.

一种多唇油封装置
本专利技术涉及一种多唇油封装置,属于密封件
技术介绍
油封,即用来封油的机械元件,它将传动部件中需要润滑的部件与出力部件隔离,不至于让润滑油渗漏,同时也阻隔外界灰尘进入需要润滑部件,起到对内封油,对外防尘的效果,广泛应用于家用电器、汽车发动机、化工等行业中。使用时油封唇部与轴发生摩擦,时间长了容易变形,影响封油、防尘等效果。
技术实现思路
目的:为了克服现有技术中存在的不足,本专利技术提供一种多唇油封装置。技术方案:为解决上述技术问题,本专利技术采用的技术方案为:一种多唇油封装置,包括橡胶密封环,橡胶密封环周部沿橡胶密封环轴向延伸设静态密封面,橡胶密封环与静态密封面之间内嵌有截面为一字型的金属骨架;橡胶密封环内侧设有动态密封组件,所述动态密封组件包括主密封唇和副密封唇,主密封唇和副密封唇外环部均设有环形凹槽,环形凹槽内设弹簧;所述副密封唇唇口为半圆形结构,所述主密封唇包括第一主密封唇和第二主密封唇;所述第一主密封唇、第二主密封唇和副密封唇唇口处分别设有浅斜纹,形成回油线。进一步地,沿着第一主密封唇和第二主密封唇设置的回油线为左旋回油线,沿着 ...
