Abstract
The utility model relates to a combined forming packing seal element, which is characterized in that: the combined forming filler-sealing element comprises a moving ring and a static ring; the moving ring is loaded into the static ring; the external circumference of the moving ring matches with the internal circumference of the static ring; the external circumference of the moving ring takes the shape of groove; the internal circumference of the static ring is convex form in correspondence to the external circumference of the moving ring; the internal circumference of the moving ring is provided with three circles of equidistance circular-arc lug boss. The static ring is made from nano modified rubber. The moving ring is made from polytetrafluoroethylene powder, copper powder, and molybdenum disulfide vulcanization molding and processed through machining. The combined forming packing seal element is a sealing element applied to industrial rotation equipment and part of reciprocation equipment such as end of roller shaft, hydraulic cylinder and reciprocating piston rod, etc. and has the advantages of good performances of wear resistance, heat resistance and corrosion resistance, no creep, no aging, long service life and that the heel of the moving ring rotates without grinding the grinding the shaft can prolong the service life of equipment.
Description
Technical field
The utility model belongs to a kind of back and forth equipment of industrial rotating equipment and part that is applied to, and sealings such as, oil hydraulic cylinder disconnected as roller shaft and reciprocating piston bar relate to a kind of combined type shaped packing seal spare.
Background technique
At present, domestic industrial rotating equipment and the reciprocal equipment of part of being applied to, a lot of as sealing materials such as roller-way axle head, oil hydraulic cylinder and reciprocating piston bars, tradition adopts the common rubber pad and the form of reinforced seal.This sealing exists: easy creep that sealing contact surface is little, rubber is heated, seal failure are fast, short weak effect of time, working life of having reduced equipment, and reinforced seal is adjacent to axle by elastic ring, have defectives such as easy to wear, installation inconvenience.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, and purpose is for industrial rotating equipment and the reciprocal equipment of part, as sealings such as roller-way axle head, oil hydraulic cylinder and reciprocating piston bars, provides a kind of combined type shaped packing seal spare.
A kind of combined type of the utility model shaped packing seal spare content Description:
The utility model combined type shaped packing seal spare, it is characterized in that: be made up of rotating ring and stationary ring, rotating ring is packed in the stationary ring, and the excircle of rotating ring matches with the inner circumference of stationary ring, the excircle of rotating ring is groove shapes, and the inner circumference of stationary ring is and the corresponding convex of the excircle of rotating ring; On the inner circumference of rotating ring, have the equidistant circular-arc boss of three circles.
Stationary ring adopts nano modification rubber to make.
Rotating ring adopts polytetrafluoroethylene powder, copper powder, molybdenum disulfide sulfidization molding, makes through machining.
The utility model combined type shaped packing seal spare is a kind of industrial rotating equipment and reciprocal equipment of part of being used for, the Sealing of, oil hydraulic cylinder disconnected and reciprocating piston bar etc. as roller shaft, have wear-resistant, the heat-and corrosion-resistant performance is good, not creep, aging, long service life, the characteristics such as working life that the rotating ring transfer is not ground axle, can be prolonged equipment.
