Abstract
An exposed framework motor shaft oil seal belongs to the technical field of oil seals. The motor shaft oil seal is used for solving the problem that the motor shaft oil seal pops up when being mounted on the shell. The rubber body wraps the outside of the framework, the upper part diameter reduction setting of the outer wall end of the framework is divided into a small diameter part and a large diameter part, the rubber body is covered on the small diameter part of the outer wall end of the framework, the upper plate end of the framework is wrapped by the inner and outer clamping of the rubber body, the inner end of the rubber body wraps the part of the framework, which is close to the edge, the inner end of the rubber body extends inwards to form a sealing lip, a spring groove is formed in the sealing lip, and a spring is installed in the spring groove. According to the utility model, the rubber coating condition of the external rubber material is changed from a full rubber coating structure to a half rubber coating structure, so that part of the framework is leaked out, the friction force is increased, the product is firmer when being installed with the shell, the problem that the product falls off when being installed on the shell can be effectively solved, and the product is more matched with the shell.
Description
Technical Field
The utility model belongs to the technical field of oil seals, and particularly relates to an exposed framework motor shaft oil seal.
Background

Detailed Description
For a better understanding of the objects, structures and functions of the present utility model, reference should be made to the following detailed description of the utility model with reference to the accompanying drawings.
As shown in fig. 1 to 5, the shaft oil seal of the exposed framework motor comprises a rubber body 1, a framework 2 and a spring 3; the rubber body 1 is wrapped outside the framework 2, the upper part diameter reduction setting at the outer wall end of the framework 2 is divided into a small diameter part 201 and a large diameter part 202, the rubber body 1 is covered on the small diameter part 201 at the outer wall end of the framework 2, the upper plate end 203 of the framework 2 is wrapped by the inner and outer clamping of the rubber body 1, the inner end of the rubber body 1 is wrapped at the part, close to the edge, of the framework 2, the inner end of the rubber body 1 extends inwards to form a sealing lip 205, a spring groove is formed in the sealing lip 205, and a spring 3 is installed in the spring groove.
The outer surface of the rubber body 1 is flush with the large diameter part 202 at the outer wall end of the framework 2.
Two circles of through holes 101 are formed in the end face of the rubber body 1. The two circles of through holes 101 are staggered.
The sealing lip 205 is provided with an inward protruding glue inlet 206.
A dust lip 204 is arranged at the inner ring of the upper surface of the rubber body 1.
It will be understood that the utility model has been described in terms of several embodiments, and that various changes and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof.
