Technical Field
The utility model belongs to the technical field of the oil blanket, concretely relates to oil blanket for broken wall machine.
Background
The oil seal is a mechanical element for sealing oil, and separates a part needing lubrication in a transmission part from a force-applying part, so that the lubricating oil is prevented from leaking. The seal of the oil seal is formed by interference fit between a flexible sealing element (leather, rubber, polytetrafluoroethylene, polychlorotrifluoroethylene, polyimide, or the like) and the rotating shaft.
The main shaft of the wall breaking machine has ultrahigh rotating speed (more than 22000 rpm), can instantaneously break the cell walls of the vegetables and the fruits and can effectively extract phytochemicals. The existing wall breaking machine oil seal is easy to deform, and the sealing effect is reduced.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an oil blanket for broken wall machine, includes skeleton and the elastic layer of cladding on the skeleton, the skeleton includes first axial portion, second axial portion, connects the connecting portion between first axial portion and second axial portion, and connecting portion set up in the upper end that is close to the elastic layer, and the inboard of elastic layer is equipped with first lip body and second lip body.
Furthermore, the cross-sectional shape of the connecting portion is set to be a circular arc shape, one end of the connecting portion is connected with the upper end of the first axial portion, and the other end of the connecting portion is connected with the upper end of the second axial portion.
Furthermore, the framework further comprises an extension part, one end of the extension part is connected with one end, far away from the connecting part, of the second axial part, and the other end of the extension part extends towards the axis side of the framework.
Further, the extension portion and the second axial portion are in circular arc transition.
Further, the first axial portion and the second axial portion are fitted together.
Further, the first lip body is arranged at the upper end of the inner side of the elastic layer, and the first lip body is obliquely arranged towards the axis side of the framework from bottom to top.
Furthermore, the inboard of elastic layer is equipped with the step, and the second lip body is fixed on the step, and the second lip body includes horizontal connecting portion and fixes the inboard perpendicular connecting portion at horizontal connecting portion, and horizontal connecting portion fix on the step.
Further, the material of the second lip body is PTFE.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the first axial part, the second axial part and the connecting part can increase the support rigidity of the oil seal, and the deformation cannot be caused by compression force or impact force;
(2) the material of second lip body sets up to PTFE, and the coefficient of friction of PTFE material is low, can use under the dry grinding environment to can realize self-lubricating, the life-span is longer.
Drawings
Figure 1 is the utility model discloses a structural schematic for oil blanket of broken wall machine.
In the figure:

2. a first lip body;
3. a second lip body; 31. a vertical connecting portion; 32. a horizontal connecting portion;
4. a framework; 41. a connecting portion; 42. a second axial portion; 43. a first axial portion; 44. an extension portion; 45. and (4) a step.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the utility model provides an oil blanket technical scheme for broken wall machine: the utility model provides an oil blanket for broken wall machine, including skeleton 4 and the elastic layer 1 of cladding on skeleton 4, the material of elastic layer 1 sets up to rubber, the material of skeleton 4 sets up to the metal, skeleton 4 includes first axial portion 43, second axial portion 42, connect connecting portion 41 between first axial portion 43 and second axial portion 42, connecting portion 41 sets up the upper end near elastic layer 1, first axial portion 43 is located the left side of second axial portion 42, second axial portion 42 is good at to the length of first axial portion 43, the inboard of elastic layer 1 is equipped with first lip body 2 and second lip body 3.
Since the material at I in fig. 1 is rubber, in the case of high compression or poor control of the installation force, the rubber is compressed, which results in deformation of the product. The first axial portion 43, the second axial portion 42 and the connecting portion 41 can increase the support rigidity at I, and neither compression force nor impact force causes deformation.
The first axial portion 43 and the second axial portion 42 are fitted together, and the supporting force at the position I can be increased.
