Abstract
A novel non-abrasion shaft oil seal comprises a rigid gland bush outer ring connected with the equipment machine frame in a relatively stationary manner and a sealing inner ring locked closely to a rotating shaft, wherein a sliding chute is arranged in the inner ring of the rigid gland bush outer ring, the sealing inner ring is arranged in the sliding chute of the rigid gland bush outer ring, andan elastic element enabling the outer ring of the sealing inner ring to be against the sliding chute of the rigid gland bush outer ring is arranged on the sealing inner ring; the rigid gland bush outer ring can be made of either metal or hard material, or the combination of the metal or the hard material and soft material; the sealing inner ring is made of either flexible abrasion resistant material, or the combination of flexible abrasion resistant material; the elastic element is a V shaped spring or elastic body elastically arranged in radial direction. In the working state of the utility model, the rigid gland bush outer ring is stationary relative to the equipment machine frame, the sealing inner ring is locked to the rotating shaft and rotates with the shaft, and during the rotation,the abrasion process takes place in the oil seal, which produces no damage on the rotating shaft.
Description
Technical field
The utility model relates to the closing element that is used for rotary component, particularly a kind of novel shafting oil envelope of not grinding.
Background technique
Modern industry production exists a large amount of speed reducers and bearing housing, and the oil seal failure of the conventional seals element in these equipment is fast, changes frequent, and the seal lip position grinds groove easily in the using process on running shaft, cause seal failure, and repair rotating shaft process trouble, costly.As Fig. 2 is common oil sealing friction position schematic representation, in working order in, friction position 7 be the friction between oil seal lip and the rotating shaft, use meeting for a long time forms groove in rotating shaft 4.
The model utility content
The utility model purpose be to provide a kind of novel can the hurtful oil sealing of countershaft.
To achieve these goals, the utility model adopts following technological scheme: a kind of novel shafting oil envelope of not grinding, comprise with the rigid gland outer shroud and the lock ring of the relative static connection of equipment rack and in the sealing of rotating shaft, encircling, rigid gland outer shroud inner ring is provided with chute, ring is arranged in the chute of rigid gland outer shroud in the sealing, and ring is provided with and makes the elastic element of ring outer ring on leaning in the chute of rigid gland outer shroud in the sealing in the sealing.
Described rigid gland outer shroud can be metal or hard material.
Ring is flexible wear-resistant material in the described sealing.
Described elastic element is V-type spring or the elastomer that elastic force is disposed radially.
The relative equipment rack of rigid gland outer shroud is static in working order for the utility model, and the ring lock ring rotates with the axis in rotating shaft in the sealing, and the friction process is carried out in oil sealing inside during running, can not cause damage by countershaft.
Description of drawings
Fig. 1 is a sectional view of the present utility model;
Fig. 2 is a common oil sealing friction position schematic representation;
Fig. 3 is the utility model friction position schematic representation.
Embodiment
The novel shafting oil envelope of not grinding as shown in Figure 1, comprise with the rigid gland outer shroud 1 and the lock ring of equipment rack 5 relative static connections and in the sealing of rotating shaft 4, encircle 2, rigid gland outer shroud 1 inner ring is provided with chute, ring 2 is arranged in the chute of rigid gland outer shroud 1 in the sealing, ring 2 is provided with and makes the elastic element 3 of ring 2 outer rings on leaning in the chute of rigid gland outer shroud 1 in the sealing, V-type spring or elastomer that elastic element 3 is disposed radially for elastic force in the sealing.
Rigid gland outer shroud 1 can be metal or hard material, also can be the combining form of metal or hard material and soft material.Ring 2 is a flexible wear-resistant material in the sealing, also can be the combining form of flexible wear-resistant material.
Fig. 3 is the schematic representation at the utility model friction position 6, the utility model is compared with traditional oil sealing, rigid gland outer shroud 1 relative equipment rack 5 is static in working order, ring 2 lock rings are in rotating shaft 4 in the sealing, rotate with the axis, the friction process is carried out in oil sealing inside during running, can not cause damage by countershaft 4.
