Description
Technical field
The utility model belongs to the closing element technical field of rotary component, is specifically related to a kind of bearing type and never grinds shafting oil envelope.
Background technique
Modern industry is produced and be there is a large amount of speed reducers and bearing housing, and the conventional seals element in these equipment is oil sealing, and Fig. 1 is shown in by its assembling schematic diagram.This oil sealing not only lost efficacy soon, change frequent, and in using process, seal lip position easily ground groove on the rotary shaft, causes seal failure, and repaired rotating shaft cumbersome, costly.
Model utility content
For prior art Problems existing, the purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of bearing type never to grind shafting oil envelope.
For achieving the above object, the technological scheme taked of the utility model is as follows:
Bearing type never grinds shafting oil envelope: comprise sealing outer shroud, sealing inner ring and ball, the inwall of sealing outer shroud is lip, the inwall of sealing outer shroud is respectively equipped with the embedded groove that coordinates and projection with respective on the outer wall of sealing inner ring along its circumference, the bottom land of groove is arc, protruding top is provided with the curve bath corresponding with the bottom land of groove, and ball is then located between the bottom land of groove and the curve bath of projection.
For easy to connect, the outer wall of sealing outer shroud and the inwall of sealing inner ring are equipped with screw thread, thus realize being threaded.
For increasing rebound elasticity and the compressibility of the sealing outer shroud contacting side with lubricant oil, an axial end of sealing outer shroud is provided with elasticity breach.
The preferred triangle in cross section of described elasticity breach.
In the utility model, the preferred lubricity of described sealing outer shroud is better, the rubber material of hard, wear-resistant, the material of the preferred rub resistance of described sealing inner ring, resilient beam, the preferred high hardness of described ball, high temperature resistant, expansion coefficient is little, the nonmetal ball of failure mode stripping type.
The utility model changes original seal form, the friction form that the friction formal transformation between oil sealing and rotating shaft is oil sealing inside, lower seal outer shroud relative device frame is static in working order, sealing inner ring lock ring rotates with the axis in rotating shaft, the process that rubs during running is carried out in oil sealing inside, can not cause damage by countershaft.
Accompanying drawing explanation
Fig. 1: the assembling schematic diagram of traditional oil sealing, A are depicted as friction position;
Fig. 2: the sectional structure schematic diagram of the utility model oil sealing;
Fig. 3: the assembling schematic diagram of the utility model oil sealing, B are depicted as friction position;
In Fig. 1-3,1, sealing outer shroud, 2, nonmetal ball, 3, sealing inner ring, 4, equipment rack, 5, rotating shaft.
Embodiment
As shown in Figure 2, bearing type never grinds shafting oil envelope: comprise sealing outer shroud 1, sealing inner ring 3 and nonmetal ball 2, the outer wall of sealing outer shroud 1 and the inwall of sealing inner ring 3 are equipped with screw thread, the inwall of sealing outer shroud 1 is lip, it is leg-of-mutton elasticity breach 11 that one axial end of sealing outer shroud 1 is provided with cross section, the inwall of sealing outer shroud 1 is respectively equipped with the embedded groove 12 and protruding 31 coordinated along its circumference separately with on the outer wall of sealing inner ring 3, the bottom land of groove 12 is arc, the top of protruding 31 is provided with the curve bath corresponding with the bottom land of groove 12, 2, ball is located between the bottom land of groove 12 and the curve bath of protruding 31.
As shown in Figure 3, in working order, sealing outer shroud 1 relative device frame 4 is static, and sealing inner ring 3 lock ring rotates with the axis in rotating shaft 5, and the process that rubs during running is carried out in oil sealing inside, can not cause damage by countershaft 5.
