Several commonly used retaining rings and their functions

There are many kinds of retaining rings: opening retaining ring (E-type card), elastic retaining ring for shaft, elastic retaining ring for hole, etc. These models are commonly used, and there are many different retaining rings that will not be introduced one by one. Let's talk about the role of these retaining rings: 1. Open retaining ring: also called open card and E-type card. Its main function is to limit the position. It is generally used on the bearing of the machine for axial positioning. 2. Elastic retaining ring for shaft: also called shaft card and external card, it is used to fix the hole image movement of the part to prevent unnecessary axial movement of the bearing. 3. Elastic retaining ring for hole: installed in a round hole and used to fix the axial movement of parts.

On the selection of the material of the sealing gasket for the environmental protection of the snap ring

Do you know the choice of raw materials for sealing gaskets? Below, follow the Xin Yongli snap ring to learn about it. The choice of gasket raw materials depends on the mining, for example: pressure, temperature, media corrosion, etc. Commonly used sealing gaskets are non-metallic gaskets, semi-metallic gaskets and metal gaskets. Non-metallic gaskets, also known as soft gaskets, such as asbestos rubber sheet, rubber, PTFE, etc., soft gaskets for temperature, pressure are not high occasions. Semi metallic gaskets are composed of metal materials and non-metallic materials, such as flexible graphite composite pads, coiled gaskets, metal coated pads, etc. Semi-metallic gaskets than non-metallic gaskets accept a wider range of temperature and pressure planning. Metal gaskets are all made of metal, with waveform, tooth, oval, octagonal, lens pad, cone pad, etc. Metal gaskets are used in high temperature and high pressure applications.

Production method of snap ring (professional snap ring, stop ring manufacturer)

There are many types of clasping, and the classification methods are different. In addition to the classification according to the relationship between the clasping and the observation line, the clasping arms are generally classified according to the production method and the number of clasping arms. Classification according to the production method: ① Casting clasp: It is made of wax type, embedded, and made of high melting alloy through casting process. The cast snap ring includes a ring-shaped snap ring and a rod-shaped snap ring. Ring-shaped clasping ring: it surrounds 3 surfaces and 4 axis angles of the abutment teeth, I .e. it surrounds more than 3/4 of the crown of the abutment teeth and is shaped like a circle, hence the name ring-shaped clasping ring. This clasper is the first application of Aker(1936), so it is also called Aker clasper. Circular ring clasping ring is suitable for periodontal tissue health, teeth

Transmission industry supplier Yongli snap ring debut Binhai

The outstanding industrial advantage has become a key factor for upstream and downstream industrial chain suppliers to "compete" along the coast. Recently, the reporter learned that Zhejiang Yongli carring signed up to participate in the 8th China World Power Transmission and skills and equipment Expo (ITCE2012 Tianjin Coastal Power Transmission Exhibition). The exhibition is jointly sponsored by China World Trade Promotion Committee Machinery Vocational Branch, Tianjin Economic and Information Committee and Zhenwei Exhibition Group. As one of the two major transmission exhibitions in China, ITCE will be held at the Coastal World Convention and Exhibition Center from August 21 to 24, with a total exhibition area of 45,000 square meters. At that time, Zhejiang Yongli snap ring will bring professional snap ring and standard parts.
