Abstract
The utility model relates to a contact sealing ring for a deep groove ball bearing. A steel framework for enhancing rigidity of the sealing ring is arranged inside the sealing ring; a contact lip of the sealing ring includes an inner upper lip, an inner lower lip and an outer lower lip, wherein the inner upper lip does not contact with an inner ring of the bearing, the inner lower lip and the outer lower lip are connected with the inner upper lip into a whole, the inner lower lip slightly contacts with the inner ring of the bearing, and the outer lower lip is in interference fit with the inner ring of the bearing. The contact sealing ring has the advantages of fine sealing performance, lower starting torque and frictional resistance and long service life.
Description
Technical field
It is good that the utility model relates to a kind of sealability, and the pivoting friction resistance is little, and the contact seal circle that is used for deep groove ball bearing of long service life belongs to seal ring and makes the field.
Background technique
Seal ring is mainly used to grease-proof and waterproof preserving and sealing gas, prevent to reveal, sealing in deep groove ball bearing, two kinds of the seal ring of branch contact-type and contactless seal rings, though contactless seal ring starting torque is little, sealability is bad, leaks grease easily, have the seal ring of a class contact-type to have only a contact lip to contact with bearing inner race, its sealability also has narrow limitation.
Summary of the invention
Purpose of design: avoid the deficiency in the background technique, design a kind of contact seal circle that is used for deep groove ball bearing, its sealability is good, and the pivoting friction resistance is little, long service life.
Design proposal: in order to realize above-mentioned purpose of design.The utility model structurally, the inside of seal ring is provided with the Steel Skeleton that increases the seal ring rigidity, the seal form of seal ring adopts the contact lip of particular design, the contact lip comprises and the discontiguous interior upper lip of bearing inner race, the endolabium and the external lower lip that fuse with interior upper lip, endolabium gently contacts with bearing inner race, external lower lip and bearing inner race interference fit.1, the design of one V-type groove is arranged between endolabium and the external lower lip, is one of technical characteristics of the present utility model.The purpose of doing like this is: make endolabium and external lower lip form the labyrinth, make sealability better; 2, endolabium gently contacts with bearing inner race, and the design of external lower lip and bearing inner race interference fit is two of a technical characteristics of the present utility model.The purpose of doing like this is: can reduce starting friction moment and operation friction moment, can not influence sealability again simultaneously; 3, near endolabium one breach is arranged between interior upper lip and the endolabium, the external lower lip oblique upper has the design of an isosceles trapezoidal groove, is three of technical characteristics of the present utility model.The purpose of doing like this is: improve the structure of endolabium and external lower lip, make endolabium and the deliquescing of external lower lip root, increase the pliability and the elasticity of endolabium and external lower lip, reduce the internal pressure that external lower lip bears simultaneously, can prevent effectively that grease from leaking; 4, interior upper lip is the helical teeth shape, and the design of tooth depth and transverse tooth thickness is four of a technical characteristics of the present utility model.The purpose of doing like this is: interior upper lip guiding lubricating grease circulates bearing inside, guarantees the good lubrication of bearing.
Technological scheme: the contact seal circle that is used for deep groove ball bearing, the inside of seal ring is provided with the Steel Skeleton that increases the seal ring rigidity, the contact lip of seal ring comprises and the discontiguous interior upper lip of bearing inner race, the endolabium and the external lower lip that fuse with interior upper lip, endolabium touches mutually with bearing inner race, external lower lip and bearing inner race interference fit.
The utility model is compared with background technique, and the one, have excellent sealing performance; The 2nd, starting torque and surface friction drag are less, long service life.
Description of drawings
Fig. 1 is the contact seal circle sectional drawing that is used for deep groove ball bearing.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.The contact seal circle that is used for deep groove ball bearing, the inside of seal ring is provided with the Steel Skeleton 8 that increases the seal ring rigidity, the seal form of seal ring adopts the contact lip of particular design, promptly contacting lip comprises and bearing inner race 5 discontiguous interior upper lips 1, the endolabium 3 and the external lower lip 6 that fuse with interior upper lip 1, endolabium 3 touches (light contact), external lower lip 6 and bearing inner race 5 interference fit mutually with bearing inner race 5.One V-type groove 4 is arranged between endolabium 3 and the external lower lip 6, near endolabium 3 groove 2 is arranged between interior upper lip 1 and the endolabium 3, external lower lip 6 oblique uppers have an isosceles trapezoidal groove 7; Interior upper lip 1 is the helical teeth shape, tooth depth and transverse tooth thickness.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
