Abstract
The utility model provides a kind of oil pocket seal arrangement of gyratory crusher, comprise freewheel coupling, mantle, seal ring, oil pocket, freewheel coupling lower shoe, described freewheel coupling lower shoe is fixed on the bottom of freewheel coupling, freewheel coupling lower shoe and mantle are bolted, between freewheel coupling lower shoe and mantle, be provided with seal ring.The oil pocket seal arrangement of a kind of gyratory crusher of the utility model, effectively raise the sealability between mantle and freewheel coupling, can prevent because heating rear mantle and oxidative phenomena appears in freewheel coupling contact position, produce iron scale, thus the phenomenon producing gap oil leakage between occurs, eliminate maintenance operatioies such as the repair weldings that leakage of oil position is carried out, add the working life of mantle, save maintenance operation time and the maintenance expenses to equipment, add the performance of enterprises.
Description
Technical field
The utility model relates to cone crusher machine equipment in ore dressing crushing technology, particularly relates to a kind of oil pocket seal arrangement of gyratory crusher.
Background technique
Certain company is from the 1600/300H gyratory crusher of equipment Imported From German EMH Company in 1989, and mantle wherein, through Long-Time Service serious wear, must be rewelded to mantle tungsten gold lining, to ensure mantle oil pocket oil closed lubrication for every 2 years.Old tungsten gold lining must first depart from by tungsten gold lining of at every turn rewelding, depart from tungsten gold to heat mantle, but there is oxidative phenomena in the mantle after heating and freewheel coupling contact position, produce iron scale, thus produce gap between, cause sealing bad, have the serious leakage of oil of pressure working state.Conventional way carries out repair welding at leakage of oil position, then carries out machined into, also will polish when mounted, waste time and energy like this, sometimes also there is leakage of oil according to actual conditions.
Summary of the invention
The purpose of this utility model is to provide a kind of oil pocket seal arrangement of gyratory crusher, the original mode by facade interference fit seal is changed into the structure shut by leakage of oil point at end face, effectively raise the sealability between mantle and freewheel coupling, can prevent because heating rear mantle and oxidative phenomena appears in freewheel coupling contact position, produce iron scale, thus the phenomenon producing gap oil leakage between occurs, eliminate maintenance operatioies such as the repair weldings that leakage of oil position is carried out, add the working life of mantle, save maintenance operation time and the maintenance expenses to equipment, add the performance of enterprises.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of oil pocket seal arrangement of gyratory crusher, comprise freewheel coupling, mantle, seal ring, oil pocket, freewheel coupling lower shoe, described freewheel coupling lower shoe is fixed on the bottom of freewheel coupling, freewheel coupling lower shoe and mantle are bolted, between freewheel coupling lower shoe and mantle, be provided with seal ring.
Described mantle is provided with an annular groove.
Described freewheel coupling lower shoe is provided with an annular groove.
The upper and lower anchor ring of described seal ring is provided with annular protrusion.
Compared with prior art, the beneficial effects of the utility model are:
A kind of oil pocket seal arrangement of gyratory crusher, the original mode by facade interference fit seal is changed into the structure shut by leakage of oil point at end face, effectively raise the sealability between mantle and freewheel coupling, can prevent because heating rear mantle and oxidative phenomena appears in freewheel coupling contact position, produce iron scale, thus the phenomenon producing gap oil leakage between occurs, eliminate maintenance operatioies such as the repair weldings that leakage of oil position is carried out, add the working life of mantle, save maintenance operation time and the maintenance expenses to equipment, add the performance of enterprises.

In figure: 1-freewheel coupling 2-mantle 3-seal ring 4-oil pocket 5-freewheel coupling 6-bolt 7-annular protrusion
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following mode of execution.
As shown in Figure 1, a kind of oil pocket seal arrangement of gyratory crusher, comprise freewheel coupling 1, mantle 2, seal ring 3, oil pocket 4, freewheel coupling lower shoe 5, described freewheel coupling lower shoe 5 is fixed on the bottom of freewheel coupling 1, freewheel coupling lower shoe 5 is connected by bolt 6 with mantle 2, between freewheel coupling lower shoe 5 and mantle 2, be provided with seal ring 3.
Mantle 2 is provided with an annular groove, and the position of groove is arranged on the surface of contact place with seal ring 3.
Freewheel coupling lower shoe 2 is provided with an annular groove, and the position of groove is arranged on the surface of contact place with seal ring 3.
Seal ring about 3 anchor ring is provided with annular protrusion 7.
Annular protrusion 7 on seal ring 3 respectively with the groove interference fit on mantle 2, freewheel coupling lower shoe 5.
Seal ring 3 adopts high-temperature resistant rubber circle, and thickness is 10mm, and upper and lower anchor ring projection height is 3mm-5mm.
Mantle 2 inside in the utility model is oil pocket 4, mantle 2 end is porose, be provided with freewheel coupling 1 in hole, freewheel coupling 1 end winding support stretched in oil pocket 4 has freewheel coupling lower shoe 5, and freewheel coupling lower shoe 5 and mantle 2 are connected and fixed by bolt 6.
Seal ring 3 is arranged between freewheel coupling lower shoe 5 and mantle 2, by clamping bolt 6 annular protrusion 7 that seal ring about 3 anchor ring is arranged is pressed in the groove on mantle 2 and freewheel coupling lower shoe 5, and seal ring 3 and freewheel coupling lower shoe 5, mantle 2 are fitted tightly.
Leakage of oil passage between freewheel coupling 1 and mantle 2 blocks by seal ring 3 completely, ensure that the sealability of gyratory crusher oil pocket, effectively extend the working life of mantle 2, reduce the engineering time to equipment and expense, save production maintenance cost.
