Abstract
The utility model relates to a sealing ring structure for a roller shaft end of a belt conveyor, and belongs to the technical field of belt conveyors. The sealing ring structure is characterized in that an inner circle sealing lip connected with a sealing ring body into a whole and a shaft sealing lip are arranged on the two sides of the sealing ring body respectively; an inward annular groove is formed in the inner circle sealing lip; the inward annular groove of the inner circle sealing lip is provided with a spiral steel wire; the spiral steel wire has a rolling trend to a diameter direction; a concave annular groove is formed in an excircle of the shaft sealing lip; and a tension spring ring is arranged in the concave annular groove in the excircle of the shaft sealing lip, and has a retracting trend to an inside diameter direction. The sealing ring structure has the advantage of better sealing effect.
Description
Technical field
The utility model relates to seal ring, relates in particular to one for idler for belt conveyer axle head special sealing ring, belongs to belt comveyer technical field.
Background technique
At present, although the seal ring sealing for the support roller shaft end bearing of belt comveyer is structurally not quite similar, but, generally exist sealing effect poor, easily make bearing inside enter dust or foreign matter, and therefore easily cause bearing damage, cause equipment work undesired, even cannot work.
Summary of the invention
The purpose of this utility model is: for the existing above-mentioned defect of existing idler for belt conveyer shaft end bearing sealed ring, the utility model provides a kind of novel idler for belt conveyer shaft end seal coil structures, overcomes the existing above-mentioned defect of existing idler for belt conveyer shaft end seal coil structures.
The utility model is realized the technological scheme that above-mentioned purpose adopts: described a kind of idler for belt conveyer shaft end seal coil structures, it comprises: sealing circle body, spiral wire, spring-pulling ring, it is characterized in that: be shaped with respectively and the inner circle sealing lip and the shaft sealing lip that seal circle body and be connected in the both sides of sealing circle body, described inner circle sealing lip outside diameter is greater than the diameter of shaft sealing lip, on described inner circle sealing lip, be shaped with inside circular groove, inside circular groove at inner circle sealing lip is provided with spiral wire, described spiral wire has to the trend of diametric(al) spreading, on the cylindrical of described shaft sealing lip, be shaped with ring fillister, in ring fillister on shaft sealing lip cylindrical, be provided with spring-pulling ring, described spring-pulling ring has the trend of shrinking to internal diameter direction.
Beneficial effect: the utility model is in concrete using process, this device is arranged on respectively symmetrically to the two ends of support roller shaft, wherein, the inner hole sleeve of shaft sealing lip is connected on above the cylindrical of axis, the cylindrical of inner circle sealing lip and the endoporus of cylinder join, and due to the effect of spiral wire, spring-pulling ring, the two ends of support roller shaft can be sealed preferably, all, the utlity model has the good advantage of sealing effect.
