Abstract
A novel double-ring split seal ring comprises a body provided with a cut, the body is split from the cut, two sections of the cut are matched to each other, and two split portions of the body are overlapped mutually along the sections. The split seal ring is provided a plurality of cuts by one design concept, the cuts can be selected to use in engineering according to practical conditions, such as, space installation requirement, sealing requirement, requirement of cut reliability and the like, and the seal ring is easy in use.
Description
Technical field
The utility model relates to a kind of seal ring, specifically is a kind of dicyclo split type seal ring.
Background technique
Most of mechanical devices all have the various axle class formations that support or rotate that have, and axial workpiece is fixed on the bearing usually, and could proper functioning under lubricating condition.It is lubricated that lubricated form has hand to annotate, drop lubrication, and ring-oil, various ways such as splash lubrication, compression are lubricated no matter adopt which kind of form, all needs axle head is carried out enough protections, in case foreign object is invaded or lubricant oil leaks.At present, relatively Chang Yong bearing protector is an integrated type, during installation, need at first be positioned at the last component of axle between the protector, then protector could be installed, and protector must be placed vertically from an end in state.If the end of protector distance axis is distant, when perhaps there were component in the protector outside, it is very inconvenient that this installation becomes, even can't install.
For this reason, people have designed various split type protectors, and the characteristics of this protector are: the annulus of protector is thought at certain disconnect in advance that off position can be called otch or interface on a bit.The existence of otch makes protector from radially being mounted for possibility, and the existence of interface simultaneously makes that again annulus becomes integral body, guarantees favorable sealing property.For reliability easy for installation and sealing, people have proposed different form of cut or cuts, these form of cut or cuts or for consideration easy for installation, and perhaps for the requirement of sealing effect, the reason that also has for manufacture cost, thereby otch also has nothing in common with each other.
On different engineerings is used, the requirement of otch is also had nothing in common with each other.
