Description
Technical field
This utility model relates to hub or bearing seal technical field, is specifically related to a kind of new structure combined seal ring.
Background technology
Being vulcanized by rubber ring and metallic framework and form, effect is used to seal inner ring and outer ring/outward flange.Metallic framework antirust treatment, rubber ring typically uses oil resistant butadiene-acrylonitrile glue or fluorubber.Combination is lined with metric system and two kinds of sizes made in Great Britain, and the quoit of combination mat adds the combining form of rubber to have standard JB982-77 to specify.Be applicable to the system that oil is medium, for preventing fluid, fuel, water and medicine etc. leak.Due to its simple in construction, seal efficiently and cheap so that it is be used widely at automobile and machinery manufacturing industry.But, the sealing effectiveness of the combined seal ring in current industry is not ideal, and sealing ring is mainly made up of quoit skeleton, rubber parts with three sealing lips；Sealing ring cover cross section principal shape is class " L ", and both are used in combination and play sealing effectiveness, it is impossible to stop dust and the Leakage of inside of outside simultaneously.
Utility model content
For the problems referred to above, this utility model aims to provide a kind of simple in construction, good sealing effect and can intercept outside entrance and the internal new structure combined seal ring overflowed simultaneously.
For realizing this technical purpose, scheme of the present utility model is: a kind of new structure combined seal ring, including sealing ring and sealing ring cover, described sealing ring cover and described sealing ring interference fit, described sealing ring cover cross section becomes " u "-shaped, described sealing ring includes that quoit skeleton and rubber bodies, described quoit skeleton are wrapped in described rubber bodies, it is characterised in that: the first sealing lip be located at outside rubber bodies and protrude the most to the outer direction；It is located at the second sealing lip protruded inside rubber bodies and along 45 degree of radially inwards of its axial class；It is located at the 3rd sealing lip protruded axially upwards inside rubber bodies and along it；It is located at the 4th sealing lip protruded inside rubber bodies and along its internal diameter direction；It is located at the 5th sealing lip protruded inside rubber bodies and along its internal diameter direction.
As preferably, the second sealing lip, the 3rd sealing lip, the 4th sealing lip and the 5th sealing lip being located on described sealing ring and described sealing ring cover interference fit, described second sealing ring coordinates with sealing the bilateral interference in ring cover external diameter direction 0.10mm-0.20mm, prevents the foreign body such as dust and mud from entering inside bearing products；Described 3rd sealing lip coordinates with the lower surface interference 0.6-0.8mm sealing ring cover, prevents the foreign bodies such as mud from entering inside bearing products；Described 4th sealing lip coordinates with sealing ring cover bilateral interference 0.60mm-0.70mm, prevents the foreign bodies such as mud from entering in the bearing of high speed rotating；Described 5th sealing lip coordinates with sealing ring cover bilateral interference 0.40-0.50mm, prevents internal grease from overflowing product, forms leakage fat.
As preferably, described first sealing lip interference bilateral with assembly outer ring 0.30-0.50mm coordinates, and described assembly outer ring is combined seal ring major diameter fit parts, prevents the foreign body such as dust and mud from entering interiors of products.
The beneficial effects of the utility model:
In Novel combined seal circle of the present utility model can effectively prevent product, oils and fats overflows formation leakage fat, in can also effectively preventing foreign body product today such as dust or mud, cause steel ball and raceway unlubricated or have foreign body to be rolled into, coefficient of friction strengthens, causing raceway abrasion to make product produce abnormal sound and damage, sealing effectiveness is greatly reinforced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is effect schematic diagram of the present utility model.
In figure: 1. sealing ring, 2. sealing ring cover, 3. rubber bodies, 31. first sealing lips, 32. second sealing lips, 33. the 3rd sealing lips, 34. the 3rd sealing lips, 35. the 5th sealing lips.
Detailed description of the invention
With specific embodiment, this utility model is described in further details below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of new structure combined seal ring of optimal specific embodiment of the present utility model, including sealing ring 1 and sealing ring cover 2, described sealing ring cover 2 and described sealing ring 1 interference fit, described sealing ring 1 includes that quoit skeleton and rubber bodies 3, described quoit skeleton are wrapped in described rubber bodies 3, and described sealing ring 1 lid cross section becomes " u "-shaped, rubber bodies 3 is additionally provided with sealing lip, the first sealing lip 31 be located at outside rubber bodies 3 and protrude the most to the outer direction；It is located at the second sealing lip 32 protruded inside rubber bodies 3 and along its axial 45 degree of internal diameter directions；It is located at the 3rd sealing lip 33 protruded axially upwards inside rubber bodies 3 and along it；It is located at inside rubber bodies 3 and the 4th sealing lip 34 that radially direction is protruded to internal diameter；It is located at inside rubber bodies 3 and the 5th sealing lip 35 that radially direction is protruded to internal diameter.
As preferably, the second sealing lip the 32, the 3rd sealing lip the 33, the 4th sealing lip 34 and the 5th sealing lip 35 and described sealing ring cover 2 interference fit being located on described sealing ring 1, described second sealing ring 32 coordinates with sealing the bilateral interference in ring cover 2 external diameter direction 0.10mm-0.20mm, prevents the foreign body such as dust and mud from entering inside bearing products；；3rd sealing lip 33 coordinates with the lower surface interference 0.6-0.8mm sealing ring cover 2, prevents the foreign bodies such as mud from entering inside bearing products；Described 4th sealing lip 34 coordinates with sealing ring cover 2 bilateral interference 0.60-0.70mm, prevents the foreign bodies such as mud from entering in the bearing of high speed rotating；Described 5th sealing lip 35 coordinates with sealing ring cover 2 bilateral interference 0.40-0.50mm, prevents internal grease from overflowing product, forms leakage fat.
As preferably, described first sealing lip 31 interference bilateral with assembly outer ring 0.30-0.50mm coordinates, and described assembly outer ring is combined seal ring major diameter fit parts, prevents the foreign body such as dust and mud from entering interiors of products.
This product be arranged on bearing or hub be naked leakage outside, the environment contacted is relatively severe, has the foreign body such as dust or mud to impact on product, such as dust or mud arrow movement direction in figure, at this moment needs exist for reasonable sealing structure and performance.Newly-increased first sealing lip can effectively avoid from L-shaped quoit and therewith interference 0.30-0.50mm coordinate the danger of entrance foreign body at ironware.Newly-increased second sealing lip and " u "-shaped seal ring cover combination can be prevented effectively from the danger entering foreign body.
What Novel combined seal circle of the present utility model can be changed prevents oils and fats spilling formation leakage fat in product, in can also effectively preventing foreign body product today such as dust or mud, cause steel ball and raceway unlubricated or have foreign body to be rolled into, coefficient of friction strengthens, causing raceway abrasion to make product produce abnormal sound and damage, sealing effectiveness is greatly reinforced.
The above; it is only preferred embodiment of the present utility model; not in order to limit this utility model, every any trickle amendment, equivalent and improvement made above example according to technical spirit of the present utility model, within should be included in the protection domain of technical solutions of the utility model.
