Abstract
The utility model discloses a sealing ring structure for high temperature and low torque, which is characterized by comprising: the framework structure comprises a first framework bending part and a second framework bending part, the first framework bending part and the second framework bending part are connected through a framework connecting part, and the bending directions of the first framework bending part and the second framework bending part are opposite; the outside parcel of skeleton texture has the sealed outer structure layer of rubber, the sealed outer structure layer of rubber's lower edge of inner lip with be provided with a plurality of bumps on the contact surface of bearing inner circle, the protruding horizontally size of stretching out is less than the extension size on the edge of inner lip. The utility model increases the firmness through the skeleton of the electrogalvanized steel plate, obviously improves the adsorption performance of the sealing ring after injection molding by increasing the salient points, reduces the torque, reduces the temperature rise of the bearing and improves the sliding phenomenon of the sealing ring.
Description
Technical Field
The utility model relates to the field of sealing ring manufacturing, in particular to a sealing ring structure for high temperature and low torque.
Background
The bearing seal ring is mainly applied to a sealing device in industrial equipment, is also called pressure seal, and is a bearing seal ring determined by using a sealing structure to enable the pressure in a sealing cavity to be different from the environmental pressure according to the principle that the physical principle is a pressure difference principle.
The existing sealing ring is easy to slip under the working conditions of high temperature and low torque.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned drawbacks of the prior art, an object of the present invention is to provide a seal ring structure for high temperature and low torque.
In order to realize the purpose of the utility model, the adopted technical scheme is as follows:
a seal ring structure for high temperature low torque applications, comprising:
the framework structure comprises a first framework bending part and a second framework bending part, the first framework bending part and the second framework bending part are connected through a framework connecting part, and the bending directions of the first framework bending part and the second framework bending part are opposite;
the outside parcel of skeleton texture has the sealed outer structure layer of rubber, the sealed outer structure layer of rubber's lower edge of inner lip with be provided with a plurality of bumps on the contact surface of bearing inner circle, the protruding horizontally size of stretching out is less than the extension size on the edge of inner lip.
In a preferred embodiment of the present invention, a protruding structure is oppositely disposed at a position between the lower edge of the inner lip and the upper edge of the inner lip of the rubber sealing outer structural layer.
In a preferred embodiment of the present invention, the bumps are first and second circular bumps.
In a preferred embodiment of the present invention, the skeleton structure is made of an electrogalvanized steel plate.
In a preferred embodiment of the present invention, the rubber sealing outer structure layer is acrylate rubber.
The utility model has the beneficial effects that:
the utility model increases the firmness through the skeleton of the electrogalvanized steel plate, obviously improves the adsorption performance of the sealing ring after injection molding by increasing the salient points, reduces the torque, and simultaneously reduces the temperature rise of the bearing, thereby improving the sliding phenomenon of the sealing ring.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1, the sealing ring structure for high temperature and low torque includes a skeleton structure 100 made of electro-galvanized steel plate, the skeleton structure 100 includes a first skeleton bending portion 110 and a second skeleton bending portion 120, the first skeleton bending portion 110 and the second skeleton bending portion 120 are connected by a skeleton connecting portion 130, and the bending directions of the first skeleton bending portion 110 and the second skeleton bending portion 120 are opposite.
The outer rubber sealing outer structural layer 200 made of acrylate rubber is wrapped outside the framework structure 100, a first circular salient point 211 and a second circular salient point 211 are arranged on a contact surface between the lower edge 210 of an inner lip of the outer rubber sealing structural layer 200 and a bearing inner ring (not shown in the figure), and the horizontal extending size of the first circular salient point 211 and the second circular salient point 211 is smaller than that of the upper edge 220 of the inner lip.
A protruding structure 230 is oppositely arranged between the lower edge 210 and the upper edge 220 of the inner lip of the rubber sealing outer structure layer 200.
The utility model increases the firmness through the skeleton structure 100 of the electrogalvanized steel plate, obviously improves the adsorption performance of the sealing ring after injection molding by increasing the salient points 211, reduces the torque, and simultaneously reduces the temperature rise of the bearing, thereby improving the sliding phenomenon of the sealing ring.
