Embodiment Construction

[0010] A kind of design method of O type rubber seal ring, this design method comprises the following steps:

[0011] (1) When using the three-dimensional design software Pro / e to design the O-shaped rubber sealing ring, design the cross-sectional shape of the O-shaped rubber sealing ring as an ellipse, and set the direction of the center line of the O-shaped rubber sealing ring to the major axis or short axis of the ellipse. The axial direction is parallel, and at the same time, the length Ry of the major axis is equal to the length Rx of the minor axis, that is, Ry=Rx, and an O-shaped rubber sealing ring in a free state is generated;

[0012] (2) When drawing the assembly drawing, use the three-dimensional model in the compressed state to flexibly process the length Ry of the major axis and the length Rx of the minor axis of the elliptical section, and adjust the length of the major axis and minor axis of the ellipse to meet the assembly requirements , adjust the l...

Abstract

The invention relates to a method for designing an O-shaped rubber sealing ring. According to the method, Pro/e software is used as a design platform; while the O-shaped rung sealing ring is constructed, the cross section of the O-shaped rubber sealing ring is designed to be oval; the direction of the central line of the O-shaped rubber sealing ring is set to be parallel to that of a long axis or a short axis of the oval; the length of the long axis Ry is equal to that of the short axis Rx, namely Ry is equal to Rx, and the O-shaped rubber sealing ring in a free state is generated; the long axis Ry and the short axis Rx of the oval cross section are subjected to flexible processing, so that flexible installation can be realized during assembly; and the long axis Ry is adjusted to be b/2, and the short axis Rx is adjusted to be (d2-d1)/4, so that interference with other assembly parts can be avoided. By the method, the condition that two different three-dimensional parts are designed in the free state and during assembly of the O-shaped rubber sealing ring, so that the O-shaped rubber sealing ring has a single figure number in a detailed statement generated during assembly can be avoided, and a database of a three-dimensional model is simplified simultaneously.

Description

[0001] technical field [0002] The invention relates to a rubber sealing ring, in particular to a design method of an O-shaped rubber sealing ring. Background technique [0003] With the continuous development of computer-aided design, three-dimensional design software has become an indispensable tool for engineering design, but for elastic components such as O-shaped rubber sealing rings, which have different dimensions in the free state and assembled state, in order to design To produce corresponding part drawings and assembly drawings, it is necessary to establish 3D models in different states, and the current 3D models use the same drawing number for both part drawings and assembly drawings, which causes confusion in the database. This utility model patent, when designing the O-shaped rubber sealing ring, its cross-sectional shape is designed to be elliptical. In the free state, the major axis and minor axis of the elliptical cross-section are set to the same value. In ...
