Abstract
The invention relates to a sealing part applied to a heavy-load rotation shaft. The sealing part applied to the heavy-load rotation shaft is of an annular structure and comprises a positioning rib ring and an elastic sealing ring. The positioning rib ring comprises a positioning ring and a sealing connecting ring, wherein the tail end of the sealing connecting ring is perpendicularly connected with the positioning ring, and the front end of the sealing connecting ring is embedded in the elastic sealing ring. The elastic sealing ring comprises a connecting ring and a sealing ring, wherein the outer surface of the sealing connecting ring of the positioning rib ring is wrapped by the front end of the connecting ring, the tail end of the connecting ring is perpendicularly connected with the sealing ring, at least two elastic reinforcing plates are additionally arranged on the contact surface of the sealing ring and the rotation shaft, and a strip-shaped sealing cavity is formed between the elastic reinforcing plates. The sealing part applied to the heavy-load rotation shaft is simple in structure, high in installation and positioning accuracy, good in abrasion resistance, high in bearing capacity, good in sealing performance and low in friction heat accumulation and moment dragging, so that the power loss of equipment and abrasion to the sealing part are greatly lowered, and the sealing reliability and stability of operation of rotation shaft components are greatly improved.
Description
Technical field
The present invention relates to a kind of Sealing for large load turning axle, belong to turning axle class water-tight equipment technical field.
Background technique
In order to improve the ride quality of equipment, usually at present, be all provided with sealing configuration at all kinds of turning axle place, be used on the one hand reducing shaft member frictional loss, the pollutant avoiding device interior to lubricate in wet goods leakage or equipment operating environment on the other hand causes damage to equipment, in order to meet this needs, the a large amount of polytype Sealing of current outlet, but find in actual use, presently used Sealing mainly adopts easy elastic packing base protection reinforced metal silk, the structure of the supporters such as metal ring, although this structure effectively can meet the needs used, but value finds in using, along with equipment far reprints the increase of lotus, the positioning precision of traditional sealing mechanism, the obvious deficiency of wear-resisting property and the equal outlet of sealability, especially when circular runout or axial float appear in shaft member class formation, current Sealing can not effectively adjust sealing configuration, thus result in sealability decline on the one hand, the structural damage that also result in Sealing is on the other hand serious, therefore for this present situation, in the urgent need to developing a kind of Sealing for large load turning axle, with the needs that satisfied reality uses.
Summary of the invention
For the deficiency that prior art exists, the invention provides a kind of Sealing for large load turning axle, this new structure is simple, installation positioning precision is high, wear-resisting property is good, bearing capacity is strong, good seal performance, frictional heat buildup and moment pull low, simultaneously while guarantee sealing is stable, separately there is good elastic strain ability, thus effectively can overcome the conventional seals drawback that sealability declines when running shaft generation circular runout and axial float, thus greatly reduce the wearing and tearing of plant capacity loss and Sealing on the one hand, reduce the working life of equipment operation energy consumption and prolongation Sealing, also improve turning axle class on the other hand greatly and build the sealing reliability and stability run, contribute to the ride quality of raising equipment.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of Sealing for large load turning axle, Sealing for large load turning axle is ring structure, comprise positioning bar ring and elastic sealing ring, positioning bar ring and elastic sealing ring coaxially distribute, wherein positioning bar ring comprises positioning ring and the ring that is tightly connected, the ring end that is tightly connected is connected with positioning ring is vertical, front end is embedded in elastic sealing ring, and positioning ring and the ring that is tightly connected are integral type structure, elastic sealing ring comprises connecting ring and seal ring, wherein connecting ring front end is coated on the ring outer surface that is tightly connected of positioning bar ring, end is connected with seal ring is vertical, seal ring and turning axle surface of contact separately establish at least two elasticity-intensified plates, and two elasticity-intensified plates be parallel to each other distribution and be 15 ° of-90 ° of angles with elastic packing ring axis, an another formation deformation Seal cage between two elasticity-intensified plates, connecting ring, seal ring and elasticity-intensified plate are integral structure.
Further, the cross-sectional configuration of positioning bar ring is in " L " shape or " J " shape structure.
Further, the connecting ring inner length that the ring that is tightly connected of described positioning bar ring is positioned at elastic sealing ring is not less than 1/3 of connecting ring maximum ga(u)ge.
Further, be linear structure or arc structure bottom described deformation Seal cage.
This new structure is simple, installation positioning precision is high, wear-resisting property is good, bearing capacity is strong, good seal performance, frictional heat buildup and moment pull low, simultaneously while guarantee sealing is stable, separately there is good elastic strain ability, thus effectively can overcome the conventional seals drawback that sealability declines when running shaft generation circular runout and axial float, thus greatly reduce the wearing and tearing of plant capacity loss and Sealing on the one hand, reduce the working life of equipment operation energy consumption and prolongation Sealing, also improve turning axle class on the other hand greatly and build the sealing reliability and stability run, contribute to the ride quality of raising equipment.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is this new structure schematic diagram.
