Abstract
The utility model provides a multi-framework type jacket sealing structure of a maintenance-free drive shaft. The multi-framework type jacket sealing structure of the maintenance-free drive shaft comprises a first L-shaped metal framework, wherein a second metal framework and a third metal framework are parallel to a short arm of the first L-shaped metal framework, and are arranged below a long arm of the first L-shaped metal framework in a spaced mode, a rubber body is arranged outside the first L-shaped metal framework in a sulfuration mode, a second polytetrafluoroethylene lip is formed between the second metal framework and the third metal framework, a first polytetrafluoroethylene lip is formed between the second metal framework and the portion, arranged on the short arm of the first L-shaped metal framework, of the rubber body, and a lip body of the first polytetrafluoroethylene lip and a lip body of the second polytetrafluoroethylene lip are arranged outwards. Due to the fact that three metal frameworks are adopted, the multi-framework type jacket sealing structure of the maintenance-free drive shaft can be firm; due to the facts that the two polytetrafluoroethylene lips are adopted, the lip bodies are arranged outwards, the first polytetrafluoroethylene lip is mainly used for preventing oil, the second polytetrafluoroethylene lip is mainly used for preventing dust, and the polytetrafluoroethylene lips are made of polytetrafluoroethylene materials, the fatigue life and the abrasion life are prolonged, the dust-proof capacity and the oil-proof capacity are improved, sealing performance is greatly improved, and the maintenance-free performance of a spline pair can be effectively ensured.
Description
Technical field
The utility model relates to the truck drive shaft component, specifically non-maintaining transmission shaft sheath boniness posture sealing configuration.
Background technique
State's intermediate solid drive shaft is the maintenance type transmission shaft at present, and the client in use needs to refuel maintaining, not high to the sealing requirements of sheath oil seal.And non-maintaining transmission shaft once refuels before dispatching from the factory, the client in use no longer refuels and maintains, and therefore very high to the sealing requirements of sheath oil seal, wear resistance, weatherability and sealability all need significantly to promote.
Summary of the invention
The utility model is in order to improve dustproof, the anti-oil preventing performance of oil sealing; Promote the oil sealing wear-out life; Promote the oil sealing weatherability, the non-maintaining transmission shaft sheath boniness posture sealing configuration of special proposition.
The technical solution of the utility model is for this reason, non-maintaining transmission shaft sheath boniness posture sealing configuration, comprise " L " shape metal frame one, be interval with two metal frames two, three parallel with galianconism under " L " shape metal frame one long-armed, the one outer sulfuration of " L " shape metal frame has rubber body, it is characterized in that: be provided with polytetrafluorethyleoil two between metal frame two and metal frame three, between the rubber body of metal frame two and " L " shape metal frame one galianconism, be provided with polytetrafluorethyleoil one.
Improvement to such scheme is: the lip direction of polytetrafluorethyleoil one and polytetrafluorethyleoil two outwardly.
Beneficial effect:
The utility model utilizes three road metal frames, make the sealing structure more firm, oil sealing adopts the twice polytetrafluorethyleoil, and all outwardly, wherein polytetrafluorethyleoil one is mainly grease proofing for the lip direction, polytetrafluorethyleoil two is mainly dustproof, adopt polytetrafluoroethylmaterial material, improved tired, wear-out life, improved dustproof and grease proofing ability, sealability significantly promotes, and can effectively guarantee non-maintaining the reaching of spline pair.
The accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
In figure, 1 is rubber body, the 2nd, and " L " shape metal frame one, 3rd, metal frame two, 4th, metal frame three, 5th, polytetrafluorethyleoil one, 6th, polytetrafluorethyleoil two.
Embodiment
The utility model as shown in Figure 1.
Non-maintaining transmission shaft sheath boniness frame sealing configuration, comprise " L " shape metal frame 1, be interval with two metal frames parallel with galianconism two, 33,4 under " L " shape metal frame 1 long-armed, the one 3 outer sulfurations of " L " shape metal frame have rubber body 1, be provided with polytetrafluorethyleoil 26 between metal frame 23 and metal frame 34, between the rubber body 1 of metal frame 23 and " L " shape metal frame one 2 galianconism, be provided with polytetrafluorethyleoil 1.
The lip direction of polytetrafluorethyleoil 1 and polytetrafluorethyleoil 26 outwardly.
Claims (2)
1. non-maintaining transmission shaft sheath boniness posture sealing configuration, comprise " L " shape metal frame one, be interval with two metal frames two, three parallel with galianconism under " L " shape metal frame one long-armed, the one outer sulfuration of " L " shape metal frame has rubber body, it is characterized in that: be provided with polytetrafluorethyleoil two between metal frame two and metal frame three, between the rubber body of metal frame two and " L " shape metal frame one galianconism, be provided with polytetrafluorethyleoil one.
