Jiangsu SWC Short Telescopic Welded Universal Coupling

SWC short telescopic welded universal coupling has the following characteristics:

1. The SWC short telescopic welded universal coupling has a high load capacity. Compared with other types of universal couplings, it can transmit large torque under the same rotation diameter. This is for mechanical equipment with strict restrictions on the rotation diameter. Important

2. The transmission of SWC short telescopic welded universal coupling reaches 98.7-, which is used for high-power transmission and saves energy significantly, which can reduce power consumption by 5-15%;

3. SWC short telescopic welded universal coupling has stable transmission and low noise. It is used for rolling mill transmission, which can improve the quality of rolled materials, improve machine performance, and the working conditions of operators.The general noise is 30-40db (A);

4. SWC short telescopic welded universal coupling has reasonable structure, use and long life;

5. The allowable inclination angle is large, up to 10°-25°.The heavy-duty cross-shaft universal coupling is the core component in the transmission system of the rolling mill, and is mainly used to transmit rolling torque.With the development of industries such as automobiles, shipbuilding, petroleum, chemical, construction, instrumentation, electronics and household appliances, the proportion of plate and strip steel in the products of my country’s steel industry is still increasing. Only the excellent performance of steel rolling equipment can cater to the market’s demand for steel. Trend of increasing demand.The performance of the transmission system of the rolling equipment determines the operating conditions of the rolling production line, so it is of great significance to conduct an in-depth analysis of the heavy-duty cross-shaft universal coupling, the core component of the main transmission system.

The heavy-duty cross-shaft universal coupling of the large-scale steel rolling equipment has poor service conditions, and is subjected to impact loads and temperature and pressure fields during operation. The equipment is suitable for large sudden loads.At higher rolling speeds, very high transmission accuracy is still required, and at the same time the thickness accuracy of the plate and strip steel is required.

The heavy-duty cross-shaft universal coupling is not only a key component of rolling mills and other equipment, but also a weak component. Once failure occurs, the entire rolling production line will stop, causing significant losses to the enterprise. Before the 20s, the super-heavy cross-shaft universal joints used by steel rolling enterprises in my country mainly relied on.In the mid-XNUMXs, domestic enterprises designed and produced super-heavy cross-shaft universal joints based on the introduction and absorption of technology, and they were widely used in domestic iron and steel enterprises.However, compared with the products of, there are still many gaps in the products produced by domestic enterprises, mainly reflected in:

(1) Lack of a complete forward design theory system.Domestic enterprises use analogy design methods to design new products on the basis of referring to the existing products of the enterprise.

(2) The product has a short service life.The service life of the same type of products is about two years, while the service life of domestic products is only about half a year.

(3) The product has poor performance.During the use of domestic products, the probability of failure accidents during the life of the product is much greater than that of products of the same type.

Relying on the mechanical characteristics of the cross shaft universal joint under heavy load conditions, this paper intends to establish a heavy load cross shaft universal joint by examining the structure, performance, working parameters, and working conditions of the heavy load cross shaft. Model, and analyze its mechanics, kinematics, dynamics, etc., find out its weak parts and optimize the structure, so as to form a complete set of design and production of heavy-duty cross-shaft universal couplings Methods provide help, and then provide theoretical support for the transformation of related results and improve the service life and quality of products.
