Abstract
The utility model relates to a special single-lip sealing ring for a deep groove bearing. The sealing ring adopts a sealing model of single-lip contract seal; a single lip is an outer lower lip in interference fit with a bearing inner race; an inner lower lip not in contact with the bearing inner race is arranged at the left of the outer lower lip; an inner upper lip not in contact with the bearing inner race is arranged above the inner lower lip; the inner upper lip, the outer lower lip and the inner lower lip are connected into a whole; a steel skeleton for increasing the rigidity of the sealing ring is arranged inside the sealing ring. The special single-lip sealing ring for the deep groove bearing has the advantages of favorable sealability, adequate bearing lubrication and long service life.
Description
Technical field
The utility model relates to the special-purpose single lip seal circle of the good zanjon bearing of a kind of sealability, belongs to seal ring and makes the field.
Background technique
Seal ring is mainly used to grease-proof and waterproof preserving and sealing gas, prevents to reveal the 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.
Summary of the invention
Purpose of design: avoid the deficiency in the background technique, design the special-purpose single lip seal circle of a kind of zanjon bearing, it touches sealing for single lipped joint, and sealability is good.
Design proposal: in order to realize above-mentioned purpose of design.The utility model structurally, the seal form of seal ring adopts single lipped joint to touch sealing, single lip is the external lower lip with the bearing inner race interference fit, the external lower lip left side has and the discontiguous endolabium of bearing inner race, the endolabium oblique upper has and the discontiguous interior upper lip of bearing inner race, interior upper lip, external lower lip and endolabium three are connected as a single entity, and the inside of seal ring is provided with the Steel Skeleton that increases the seal ring rigidity.1, the design of external lower lip and bearing inner race interference fit is one of technical characteristics of the present utility model.The purpose of doing like this is: strengthened sealability greatly, prevented that grease from leaking.2, between external lower lip and the endolabium V-shaped groove is arranged, the external lower lip oblique upper has dovetail groove, and the design of a breach is arranged between endolabium and the interior upper lip, is two of technical characteristics of the present utility model.The purpose of doing like this is: improve the structure of external lower lip, make the deliquescing of external lower lip root, increase the pliability and the elasticity of external lower lip, reduced the internal pressure that external lower lip bears simultaneously, can prevent effectively that grease from leaking.3, interior upper lip is thick and hard, and interior upper lip is the design of helical teeth shape, is three of 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 special-purpose single lip seal circle of zanjon bearing, it comprises seal ring, the seal form of described seal ring adopts single lipped joint to touch sealing, single lip is the external lower lip with the bearing inner race interference fit, the external lower lip left side has and the discontiguous endolabium of bearing inner race, the endolabium oblique upper has and the discontiguous interior upper lip of bearing inner race, and interior upper lip, external lower lip and endolabium three are connected as a single entity, and the inside of seal ring is provided with the Steel Skeleton that increases the seal ring rigidity.
The utility model is compared with background technique, has excellent sealing performance, bearing lubrication abundance, long service life.

Fig. 1 is the special-purpose single lip seal circle generalized section of zanjon bearing.
The drawing reference numeral explanation
Embodiment
Embodiment 1: with reference to accompanying drawing 1.The special-purpose single lip seal circle of zanjon bearing, it comprises seal ring, the seal form of seal ring adopts single lipped joint to touch sealing, single lip is the external lower lip 3 with the bearing inner race interference fit, external lower lip 3 left sides have and the discontiguous endolabium 6 of bearing inner race, endolabium 6 oblique uppers have and the discontiguous interior upper lip 4 of bearing inner race, interior upper lip 4, external lower lip 3 and endolabium 6 threes are connected as a single entity, the inside of seal ring is provided with the Steel Skeleton 1 that increases the seal ring rigidity, between external lower lip 3 and the endolabium 6 V-shaped groove 7 is arranged, external lower lip 3 oblique uppers have dovetail groove 2, between endolabium and the interior upper lip groove are arranged.One breach 5 is arranged between endolabium 6 and the interior upper lip 4, and interior upper lip 4 is thick and hard, and interior upper lip 4 is the helical teeth shape.
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.
