Abstract
The utility model provides a take the joint bearing of sealing washer, include: outer lane and inner circle, its characterized in that still includes: inside seal circle and external seal circle, has the inside seal groove on the inner wall of inner circle, including inside seal circle sets up in the seal groove. Have the external seal groove on the inner wall of outer lane, the external seal circle sets up at the external seal inslot. Its advantage lies in the sealed of an inside seal circle load joint bearing hole and main shaft, prevents the downward seepage of lubricating grease, the external seal encloses sealing like the joint bearing load sliding ball face of conventionality, sealed dustproof effectual, bearing life has increased by 60%.
Description
Technical field
This utility model relates to a kind of oscillating bearing with sealing ring, particularly to a kind of oscillating bearing with sealing ring being applied to gyratory crusher.
Background technology
Fig. 1 is the structure chart of existing hydraulic single-cylinder gyratory crusher.
As it is shown in figure 1, supporting adopts steel bushing 2 on existing hydraulic single-cylinder gyratory crusher, sliding surface adopts the grease lubrication that viscosity is low；This just requires that port should reliably packing grease, it is prevented that it flows downward out, and prevents dust from ascending into, with main shaft, the face of being slidably matched again.The sealing ring 3 commonly used at present, will take into account above-mentioned two tasks, and actual effect is not good, it is easy to damage.
The reason that existing sealing ring 3 is easily damaged is: main shaft 1 has axially-movable at work, and the spindle face leaked outside has dirt to adhere to so that the easy wear damage of sealing ring；Main shaft also has swing campaign so that the monolateral deformation of exterior seal ring is big, adds difficulty that is dust-proof and that seal.
Utility model content
The purpose of this utility model aims to provide a kind of oscillating bearing with sealing ring, it is possible to have flexible rotating and good sealing property simultaneously, to overcome the existing defects of above-mentioned prior art.
This utility model provides a kind of oscillating bearing with sealing ring, including: outer ring and inner ring；It is characterized in that, also include: inner seal ring and exterior seal ring；Having interior seal groove on the inwall of inner ring, inner seal ring is arranged in interior seal groove.Having external seal groove on the inwall of outer ring, exterior seal ring is arranged in external seal groove.
Further, this utility model provides a kind of oscillating bearing with sealing ring, it is also possible to have a feature in that inner seal ring has sealing lip.
Further, this utility model provides a kind of oscillating bearing with sealing ring, it is also possible to have a feature in that the sealing lip of inner seal ring upwards.
Further, this utility model provides a kind of oscillating bearing with sealing ring, it is also possible to have a feature in that external seal groove is stepped hole；The profile of exterior seal ring and external seal groove match.
Further, this utility model provides a kind of oscillating bearing with sealing ring, it is also possible to have a feature in that exterior seal ring has sealing lip.
Further, this utility model provides a kind of oscillating bearing with sealing ring, it is also possible to have a feature in that the sealing lip of exterior seal ring is downward.
It addition, this utility model also provides for a kind of gyratory crusher, including main shaft and the above-mentioned oscillating bearing with sealing ring；Oscillating bearing with sealing ring is enclosed within main shaft.
Further, this utility model also provides for a kind of gyratory crusher, it is also possible to has a feature in that and also includes support and dust ring；Dust ring arranges with below the oscillating bearing of sealing ring, and is between support and main shaft.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
Fig. 2 is the structural representation of gyratory crusher of the present utility model.
As in figure 2 it is shown, gyratory crusher includes: main shaft 1, oscillating bearing 100 with sealing ring, dust ring 4 and support 5.
Oscillating bearing 100 with sealing ring is enclosed within main shaft 1, the centre bore of main shaft 1 traverse support 5.Oscillating bearing 100 with sealing ring is between main shaft 1 and support 5.Dust ring 4 is arranged below the oscillating bearing 100 with sealing ring, and is between support 5 and main shaft 1.
Fig. 3 is the structural representation of the oscillating bearing with sealing ring of the present utility model.
Fig. 4 is the I portion enlarged drawing of Fig. 3.
As shown in Figure 3 and Figure 4, the oscillating bearing with sealing ring includes outer ring 10, exterior seal ring 20, inner ring 30 and inner seal ring 40.
The spherical outside surface of inner ring 30 and the Internal Spherical Surface of outer ring can be slided.
The inwall of outer ring 10 has external seal groove.External seal groove is stepped hole.The profile of exterior seal ring 20 and external seal groove match.Exterior seal ring 20 is arranged in external seal groove.Exterior seal ring 20 has sealing lip, and sealing lip is downward.
The inwall of inner ring 30 has interior seal groove.Inner seal ring 40 is arranged in interior seal groove.Inner seal ring 40 has sealing lip, and lip is upwards.
A kind of gyratory crusher that this utility model provides is replaced by the oscillating bearing with inner seal ring upper support steel bushing sliding bearing.The inner seal ring of oscillating bearing only undertakes the sealing of oscillating bearing endoporus and main shaft, it is prevented that the downward seepage of grease.Oscillating bearing exterior seal ring undertakes the sealing of slip sphere as conventional oscillating bearing.Dust ring is only undertaken and is prevented dust to be upwardly into oscillating bearing sliding surface with main shaft.
The division of labor of sealing ring, dust ring clearly, in the design and material selection of lip, all becomes very targeted, and sealing and dustproof is effective, and bearing adds 60% service life.
