Abstract
The utility model relates to a bearing sealing structure which comprises a first sealing lip (1), a second sealing lip (2), a third sealing lip (3) and a rib (100), and a fourth sealing lip (4) is also arranged between the first sealing lip (1) and the second sealing lip (2). The utility model has the advantages of good sealing effect of the bearing, great improvement of service life, and great improvement of reliability requirement of a generator.
Description
Technical field
The utility model relates to a kind of bearing, relates in particular to a kind of bearing seal structure.
Background technique
As seen from Figure 1: its sealing configuration of seal deep groove ball bearing of the prior art all is to rely on very big magnitude of interference to play the erosion of sealing muddy water, the bearing of this structure is in the course of the work because friction torque is big, thereby make the temperature rise of bearing too high, thereby have influence on the life-span of bearing, in addition, for the intrusion of muddy water in the course of the work is unavoidable, and the reliability of bearing is low.This can't satisfy the requirement of automobile current generator.Among the figure: first seal lip 1, second lip of seal 2, the 3rd seal lip 3, rib 10.
As the bearing seal of generator, because its Environmental Conditions is abominable: be exposed in brush wear powder and the environment from external dust, muddy water, under high temperature, high loading, running from low speed to high speed; So the requirement to it will have reliability.
Summary of the invention
The utility model technical issues that need to address have provided a kind of bearing seal structure, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: first seal lip, second lip of seal, the 3rd seal lip, retaining; Between described first seal lip and second lip of seal, also comprise the 4th seal lip; Described first seal lip is close to the seal groove step place of rib; Second lip of seal and the 4th seal lip are close to the side of the seal groove of rib with certain elasticity interference; The seam of the inner ring of the 3rd seal lip and rib directly forms certain clearance.
Compared with prior art, the beneficial effects of the utility model are: make the sealing effect of bearing fine, be greatly improved working life, greatly improved the reliability requirement of generator.
Description of drawings
Fig. 1 is the structural representation of bearing seal of the prior art;
Fig. 2 is a structural representation of the present utility model;
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: first seal lip 1, second lip of seal 2, the 3rd seal lip 3, rib 100; Between described first seal lip 1 and second lip of seal 2, also comprise the 4th seal lip 4; Described first seal lip 1 is close to the seal groove step place of rib 100; Second lip of seal 2 and the 4th seal lip 4 are close to the side of the seal groove of rib 100 with certain elasticity interference; The 3rd seal lip 3 directly forms certain clearance with the seam of the inner ring of rib 100.
The utility model makes first seal lip be close to seal groove step place, forms one seal clearance in the bearing working process herein, makes grease be difficult to spill from here; Second lip of seal and the 4th seal lip tightly are attached to the side of seal groove with certain elasticity interference, the immersion that relies on the elasticity of magnitude of interference and sizing material to resist muddy water; The seam of the 3rd seal lip when design and inner ring directly forms certain clearance, but under the interference of two lips in side, the 3rd seal lip just directly forms the gap that needs with the inner ring seam, this gap not only can stop entering in the seal groove of outside dust, and the water that enters seal groove is in time discharged from this place.
The utility model can use under very harsh operating conditions, and as in a large amount of dust are arranged or muddy water, external temperature are arranged between-40 ℃ ~ 170 ℃, the protective measure that does not need to add other just can reach the life-span of actual demand.It can be applied in widely has in the various environment of specific (special) requirements the bearing seal performance, and simple in structure, is easy to make.
Claims (2)
1. a bearing seal structure comprises: first seal lip (1), second lip of seal (2), the 3rd seal lip (3), rib (100); It is characterized in that: between described first seal lip (1) and second lip of seal (2), also comprise the 4th seal lip (4).
2. bearing seal structure according to claim 1 is characterized in that: described first seal lip (1) is close to the seal groove step place of rib (100); Second lip of seal (2) and the 4th seal lip (4) are close to the side of the seal groove of rib (100) with certain elasticity interference; The 3rd seal lip (3) directly forms certain clearance with the seam of the inner ring of rib (100).
