Abstract
The utility model provides a compound seal of ball cage universal joint for mechanical equipment transmission system such as vehicle. Annular cooperation on inside seal main aspects internal diameter and the ball cage universal joint overcoat excircle, card are in the annular, and inside seal tip internal diameter cooperates with the integral key shaft excircle of ball cage universal joint, hugs closely the integral key shaft excircle, the dust cover is equipped with to the inside seal outside, and the inside seal main aspects are fixed on the overcoat excircle through big clamp with the dust cover main aspects together, dust cover tip and the outer annular groove cooperation of integral key shaft, and the card is fixed on the integral key shaft excircle through little clamp in the annular, the inside seal shape is flexural mode curve structure, and the inside seal tip is elasticity lip structure. The utility model discloses the inside seal can play the grease effect of sealing up up for safekeeping alone, when the dust cover is damaged, can guarantees the grease all the time and not reveal, can block that lubricating grease at work to the dust cover internal flow, guarantees that the inside grease of ball cage universal joint concentrates on work lubricating region territory, has improved lubricating efficiency and validity, adapts to the requirement of ball cage cardan axis to great flexible volume.
Description
Technical field
This utility model is related to technical field of mechanical transmission, specifically a kind of for the plant equipment drive system such as vehicle
Cage universal joint compound seal.
Background technology
Existing cage universal joint is sealed into ripple type dust cover, and its one end is fixed on and puts outside cage universal joint, the other end
It is fixed on universal-joint splined shaft.When cage universal joint rotates, this dust cover can preserve oils and fatss, prevents extraneous dust etc.
Foreign body enters inside universal joint.But under use condition relatively rugged environment, dust cover breakage easily occurs, what oils and fatss were revealed shows
As, particularly operation in the wild when, this problem is more prominent.
Content of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of cage universal joint to be combined close
Envelope, seals oils and fatss up for safekeeping by interior sealing, when dust cover is damaged, still ensure that oils and fatss are not revealed, improves cage universal joint
Environmental suitability and reliability.
For realizing above-mentioned utility model purpose, compound seal of the present utility model includes interior sealing and dust cover；Interior sealing
Big end internal diameter and cage universal joint overcoat cylindrical on annular groove cooperation, be stuck in annular groove, the small end inner diameter of interior sealing and ball
The cylindrical cooperation of the splined shaft of cage universal joint, is close to the cylindrical of splined shaft；The outside of interior sealing equipped with dust cover, interior sealing big
End pass through together with the big end of dust cover big clip be fixed on overcoat cylindrical on, the small end of dust cover and the outer toroid of splined shaft
Groove coordinate, be stuck in annular groove, by little clip be fixed on splined shaft cylindrical on；Described interior sealing be shaped as flexure type curve
Structure, the small end of interior sealing is elastic lip configuration.
Described elasticity lip configuration is single lip configuration, and single lip configuration is single O-ring structure.
Described elasticity lip configuration is lips mouth structure, and lips mouth structure is double O-ring structures arranged side by side.
The big end internal diameter of described interior sealing, dust cover big end internal diameter cylindrical with overcoat respectively on annular groove cooperation, respectively
Be stuck in annular groove, by big clip be fixed on overcoat cylindrical on.
Described dust cover is flexure type curvilinear structures or wavy shaped configuration.
This utility model compared with prior art, has advantages below：
1st, the interior sealing of compound seal can individual play the effect sealing oils and fatss up for safekeeping, when dust cover is damaged, all the time can
Ensure that oils and fatss are not revealed.
2nd, interior sealing can stop that grease, at work to dust cover internal flow, reduces cage universal joint internal grease
The oil resistivity of dust cover is required.
3rd, interior sealing can ensure that cage universal joint internal grease concentrates on working lubrication region, improve lubricating efficiency and have
Effect property.
4th, the elastic lip of interior sealing can carry out, on splined shaft, the sealing that slides axially, can adapt to cage cardan axis to
The requirement of larger stroke.
5th, easy to maintenance, it is widely used as metallurgy, petroleum machinery, the sealing of special vehicle cage universal joint.

Specific embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, this utility model compound seal includes interior sealing 3 and dust cover 4；Interior sealing 3
Big end internal diameter and cage universal joint overcoat 1 cylindrical on annular groove cooperation, be stuck in annular groove, the small end inner diameter of interior sealing 3 with
The cylindrical cooperation of the splined shaft 6 of cage universal joint, is close to the cylindrical of splined shaft 6；The outside of interior sealing 3 is equipped with dust cover 4, interior close
The big end of envelope 3 together with the big end of dust cover 4 by big clip 2 be fixed on overcoat 1 cylindrical on, the small end of dust cover 4 and flower
Key axle 6 annular groove outside cooperation, be stuck in annular groove, by little clip 5 be fixed on splined shaft 6 cylindrical on；Described interior sealing 3
According to the interior spatial structure of dust cover 4, its shape is designed as flexure type curvilinear structures, can meet close during cage universal joint pivot angle
Envelope deformation requirements, the small end of interior sealing 3 is elastic lip configuration, and interior sealing 3 can individual play the effect sealing oils and fatss up for safekeeping, when anti-
When dust hood 4 is damaged, ensure that oils and fatss are not revealed all the time, stop grease at work to dust cover 4 internal flow it is ensured that ball
Cage universal joint internal grease concentrates on working lubrication region, and the elastic lip of interior sealing 3 can be slid axially on splined shaft 6
Sealing, can adapt to cage cardan axis to the requirement of larger stroke.
The small end of described interior sealing 3 is elastic lip configuration, and elastic lip configuration can be single lip configuration, lip shape
It is similar to single O-ring.The small end of interior sealing 3 can also be lips mouth structure, and lip is shaped like double O-ring arranged side by side.
The big end internal diameter of described interior sealing 3, dust cover 4 big end internal diameter also can cylindrical with overcoat 1 respectively on annular groove join
Close, be stuck in annular groove, respectively by big clip 2 be fixed on overcoat 1 cylindrical on.
Described dust cover 4 is flexure type curvilinear structures or wavy shaped configuration.
