摘要： A tube seal (10) includes a cylindrical tube (12) and an elastomeric seal body (14) molded to the cylindrical tube. The elastomeric seal body includes a pair of seal lip regions (16, 18) extending from opposite ends of the rigid cylindrical tube and inserted into a respective bore of a pair of opposing members (20, 22) for providing a sealing relationship there between. The seal lip regions each include, in an unassembled condition, an axially extending seal lip (28) and a radially outwardly extending seal lip (30) connected to the ends of the rigid cylindrical tube by an elastomeric hinge region (40).

摘要： A seal system for a reciprocating cylinder includes a buffer seal, a rod seal, and a wiper seal. The buffer seal includes a dynamic seal lip and a static lip extending from a hinge portion. The hinge portion of the static lip allows fluid to escape past the outer diameter of the seal when the rod is retracted thereby releasing any pressure build-up between the rod seal and buffer seal. The axial face portion of the dynamic seal lip includes axially extending notches therein. The notches prevent the buffer seal from sticking to the axial wall of the groove and provide a consistent path for the fluid to energize the annular groove between the static and dynamic lips during the extension phase which is necessary for the function of the seal. The back-up ring is an integrated part of the buffer seal, used to provide superior extrusion resistance. The rod seal includes an annular seal body having a dynamic seal lip angularly extending radially inwardly and axially from the seal body, and a static lip angularly extending radially outwardly and axially from the seal body. An axial face portion of the dynamic seal lip and the static lip each include radially extending notches therein. The notches prevent the seal from sticking to the axial walls of the groove the rod seal is installed in and provides a consistent path for the fluid to energize the annular groove created by the static and dynamic lip during the extension phase. The back-up ring is an integrated part of the rod seal, used to provide superior extrusion resistance.
摘要翻译：用于往复式气缸的密封系统包括缓冲密封件，杆密封件和擦拭器密封件。缓冲密封件包括动态密封唇缘和从铰链部分延伸的静态唇缘。当杆缩回时，静态唇缘的铰链部分允许流体逃离密封件的外径，从而释放杆密封件和缓冲密封件之间的任何压力积聚。动态密封唇的轴向面部分包括其中轴向延伸的凹口。凹口防止缓冲密封件粘附到凹槽的轴向壁上，并提供一致的路径，用于使流体在密封件的功能所需的延伸阶段期间激励静态和动态唇缘之间的环形凹槽。备用环是缓冲密封件的集成部件，用于提供优异的挤出阻力。杆密封件包括环形密封体，其具有从密封体径向向内和轴向成角度地延伸的动态密封唇，以及从密封体径向向外且轴向地延伸的静态唇缘。动态密封唇缘和静态唇缘的轴向面部各自包括径向延伸的凹口。凹口防止密封件粘附到凹槽的轴向壁上，杆密封件安装在该轴向壁中，并且提供一致的路径，以使流体在延伸阶段期间由静态和动态唇缘产生的环形凹槽通电。支撑环是杆密封件的集成部件，用于提供优异的挤压阻力。

摘要： A bi-directional dynamic seal advantageously provides for the return of captured lubricant to the lubricant side regardless of a direction of relative rotation between the seal and the shaft. The seal utilizes a pattern of symmetrical pumping elements to facilitate the hydrodynamic pumping of the captured lubricant in response to the relative rotation. The symmetrical pumping elements have ending points that stop short of the seal edge of the seal. The seal may utilize secondary pumping elements that communicate with the primary pumping elements to capture lubricant that is not captured by the primary pumping elements.

摘要： An admixture of thermoplastic polymer (such as thermoplastic elastomer), cured elastomeric polymeric material (such as thermoset elastomer), and magnetizable (ferrite) powder provide a thermoplastic elastomer featuring a relatively high loading of a magnetizable material. The admixed magnetizable thermoplastic elastomer composition, optionally cured, provides robust material properties along with good forming properties for molding magnetic components. This material is advantageous for a magnetic target wheel in an encoder.
