Abstract
The utility model relates to a seal device, in particular to a detachable waterproof oil seal which overcomes such disadvantages of the existing combined oil seal as higher installation resistance of the seal body, bad lubrication effect, bad dustproof and waterproof effects and undetachable maintenance. The utility model comprises an inner seal body and an outer seal body; wherein, the rubber edge on one side which is exposed to the air of the outer seal body is flanged to wrap the frame of the inner oil seal; two segments of corrugations are arranged on the peripheral surface of the inner seal body; namely, the corrugations are respectively arranged on the upper and the lower ends of the circumference surface; an oil storage groove is arranged between the two segments of the corrugations; a circular arc positioning lug boss is arranged on the position where the bottom of the outer sealing body is contacted with the inner seal body. The detachable waterproof oil seal has the advantages of simple structure, low installation resistance, firm connection of the inner and the outer seal bodies, convenient positioning, good dustproof and waterproof effects, convenient detachment of the inner and the outer seal bodies and convenient maintenance.
Description
Technical field
The utility model relates to seal arrangement, specifically a kind of detachable anti-muddy water oil sealing of anti-mud waterproof.
Background technique
Along with the continuous development of automotive industry, more and more higher to the requirement of oil sealing.Along with the continuous variation of operating conditions, adapted to operating conditions in order to make oil sealing, people design different oil sealings to improve its sealability, prolong its working life.On the basis of monomer Sealing designing car the oil sealing of various structures such as combined type oil sealing, it has improved the sealability of oil sealing, but also has certain defective when using.The problem that combined type oil sealing commonly used at present exists is: its installation resistance was bigger when inner oil seal was installed on the running shaft, lubrication effect is relatively poor in use, the dustproof effect that discharges water of oil sealing is relatively poor, and is difficult for dismantling maintenance after the long-time use of oil sealing goes wrong.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of existing combined type oil sealing, a kind of detachable anti-muddy water oil sealing has been proposed, it is simple in structure, the installation resistance is little, be connected firmly between the inside and outside seal, be convenient to the location, the dust and water protection effect is better, and inside and outside seal convenient disassembly is convenient to maintenance.
The utility model is to adopt following technological scheme to realize: a kind of detachable anti-muddy water oil sealing, and seal and external sealed body in comprising, wherein, external sealed body air side rubber periphery flange encases the skeleton of inner oil seal.
In the utility model, on interior seal outer circumferential face, the segmentation ripple is set, promptly ripple is set respectively at the two ends up and down of circumferential surface, between two sections ripples oil storage tank is set, the bottom of seal and inner oil seal contacting point are provided with the circular arc type positioning boss outside, a plurality of sealing and dustproof lips are set on the external sealed body, form the labyrinth oil seal end face.The external sealed body adopts corrugated cylindrical structure.On the fixing present hole of external sealed body, interior seal rotates together with the axis, and inside and outside seal rotates relatively.
The beneficial effects of the utility model are: (1) is owing to the outer surface at interior seal, promptly directly and on the surface of contact of running shaft the segmentation ripple is set, between each section ripple, oil storage tank is set, reduced the assembling area of contact, thereby increased assembling elasticity, reduced the installation resistance of inner oil seal; (2) by the bottom and the interior seal contacting point of seal outside the circular arc type positioning boss is set, makes oil sealing be easy to the location, and make oil sealing be convenient to install; (3) by external sealed body air side rubber periphery flange, the external sealed body is encased interior seal, thus the time can firmly connect between the inside and outside seal, simultaneously can dustproof and waterproof, can dismantle maintenance to oil sealing and change by the elasticity of rubber simultaneously; (4) be convenient to install,, make this oil sealing be convenient to install on present hole and the running shaft because ripple is set respectively on inside and outside seal; (5) by on the seal a plurality of dust excluder lips being set outside, improved its sealing effect, main lip, dust excluder lips place add lubricating grease, have avoided the dry friction of lip.
Description of drawings
Fig. 1 is the utility model embodiment's a sectional view.
Embodiment
The utility model embodiment's overall structure as shown in Figure 1, it comprises external sealed body 1 and interior seal 3.On the outer peripheral surface of interior seal 3, promptly the two ends up and down with the surface of contact of running shaft are provided with ripple 4 respectively, and oil storage tank 5 is set between two sections ripples 4, scribble lubricating grease in the oil storage tank 5.Interior seal 3 rotates with running shaft, in rotary course, because the effect of lubricating grease obtains sufficient lubrication between seal 3 and the running shaft in making, has prolonged its working life.In addition because the installation of interior seal 3 is convenient in the setting of ripple 4.The bottom of seal 1 outside, with the contacting point of interior seal 3 several circular arc type positioning boss 7 are set, it helps the integral installation of oil sealing, the location of seal 3 in being convenient to, in addition, the outer circumferential face rubber flange of external sealed body 1 encases the skeleton 2 of interior seal 3, and seal 3 firmly is connected with external sealed body 1 in making.Owing to adopted the rubber flange, therefore can dismantle oil sealing by the elasticity of rubber, be convenient to the replacing of inside and outside seal, make oil sealing have dustproof and waterproof simultaneously.On the outer peripheral surface of seal 1 ripple is set outside, is convenient to it is installed in the present hole.
A plurality of dust excluder lips 6 are set on the seal 1 outside, form the design of mazy type end face, by a plurality of dust excluder lips are set, strengthened the dustproof effect of oil sealing, between dust excluder lips 6 and interior seal 3, scribble lubricating grease, avoided the friction of lip on the external sealed body 1, prolonged the working life of oil sealing.
This kind oil seal structure is simple, is convenient to install, and the dustproof and waterproof effect is better, and inside and outside seal is connected firmly, and interior seal accurate positioning, is convenient to oil sealing is carried out dismounting and change, has prolonged its working life, is particularly useful for the lower occasion of rotating shaft rotating speed.
