Abstract
The utility model discloses a sealing structure of a cone crusher. The sealing structure comprises a body and a bowl-shaped bearing frame. The sealing structure is characterized in that a bowl-shaped tile is arranged between the body and the bowl-shaped bearing frame; a lower sealing ring is sleeved outside the bowl-shaped bearing frame; the body is provided with a spherical ring which is adhered to the lower sealing ring; and sealing layers are arranged between the spherical ring and the bowl-shaped bearing frame and between the spherical ring and the lower sealing ring as well. An extra spherical ring is arranged on a contact spherical outer ring of the body and the bowl-shaped tile; and an extra lower sealing ring is arranged above the bowl-shaped bearing frame to contact with the two spherical rings of the body. The sealing structure disclosed by the utility model enables dust not to enter the structure, prolongs the service cycle of the lubricating oil, prevents pollution of the lubricating oil, lowers the application cost, and further prolongs the service life of the machine.
Description
Technical field
The utility model relates to a kind of sealing configuration, and in particular, the utility model relates to a kind of gyratory crusher sealing configuration.
Background technique
At present, gyratory crusher bowl-type bearing portion, originally design arranges intake pipe, the water sealing and dustproof on the bowl-type bearing bracket stand.The constantly friction in rotary oscillation due to spherical circle and rubber seal ring causes distortion, does not just have dustproof effect after use a period of time, and a large amount of dust is entered, and causes lubricant pollution serious, and will change oil average 1 ~ February.The waste of lubricant oil, user cost increases, and has also greatly affected the working life of machine.
The model utility content
The purpose of this utility model is to solve existing above-mentioned problem, and a kind of gyratory crusher sealing configuration is provided.
For realizing above purpose, the technical solution of the utility model is a kind of gyratory crusher sealing configuration, comprise body and bowl-type bearing bracket stand, it is characterized in that, be provided with bowl-shaped tile between described body and bowl-type bearing bracket stand, described bowl-type bearing bracket stand outer cover is provided with lower sealing ring, and described body is provided with ball collar, described ball collar and lower sealing ring are fitted, and are equipped with sealing layer between described ball collar and bowl-type bearing bracket stand and lower sealing ring.The sphere outer shroud that contacts with bowl-shaped tile at body increases ball collar, and lower sealing ring of bowl-type bearing bracket stand top increase contacts with body twice ball collar, has increased sealing effect, has improved working life.
As preferably, be provided with holddown spring below described lower sealing ring, described bowl-type bearing bracket stand is provided with fixed groove, and described holddown spring is arranged in fixed groove.Holddown spring makes lower sealing ring and body twice ball collar close contact, increases sealing effect.
As preferably, described lower sealing ring lower end internal surface is provided with O-ring seals, and described O-ring seals and bowl-type bearing bracket stand are fitted.O-ring seals increases the sealing between bowl-type bearing bracket stand and lower sealing ring.
As preferably, described sealing layer is the sealing layer that is comprised of drier oil fat.By the sealing layer that drier oil fat forms, good sealing effect.
The utlity model has following beneficial effect: dust can not enter inside, and the lubricant oil life cycle increases, and has avoided the contamination phenomenon of lubricant oil, and user cost reduces, the working life of also greatly having improved machine.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
1, body; 2, bowl-shaped tile; 3, lower sealing ring; 4, holddown spring; 5, bowl-type bearing bracket stand; 6, sealing layer; 7, O-ring seals; 8, ball collar; 9, fixed groove.
Embodiment
Below in conjunction with specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described:
embodiment: gyratory crusher sealing configuration (seeing accompanying drawing 1), comprise body 1 and bowl-type bearing bracket stand 5, be provided with bowl-shaped tile 2 between described body 1 and bowl-type bearing bracket stand 5, described bowl-type bearing bracket stand 5 outer cover are provided with lower sealing ring 3, described body 1 is provided with ball collar 8, described ball collar 8 is fitted with lower sealing ring 3, be equipped with sealing layer 6 between described ball collar 8 and bowl-type bearing bracket stand 5 and lower sealing ring 3, described sealing layer 6 is the sealing layer that is comprised of drier oil fat, described lower sealing ring 3 belows are provided with holddown spring 4, described bowl-type bearing bracket stand 5 is provided with fixed groove 9, described holddown spring 4 is arranged in fixed groove 9, described lower sealing ring 3 lower end internal surfaces are provided with O-ring seals 7, described O-ring seals 7 is fitted with bowl-type bearing bracket stand 5.
Improve body, the sphere outer shroud that contacts with bowl-shaped tile at body increases the twice ball collar; Improve the bowl-type bearing bracket stand, contact increasing above the bowl-type bearing bracket stand under a lower sealing ring and the effect of body twice ball collar at spring; Add certain dry oil lubrication fat between body bipassage ring and lower sealing ring.Dust can not enter inside like this, and the lubricant oil life cycle increases, and has avoided the contamination phenomenon of lubricant oil, and user cost reduces, the working life of also greatly having improved machine.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model is limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
