目前,国内外机械工程设计中被广泛应用的联接有螺纹联接,键、销联接,花键联接,过盈联接,铆钉联接等,并已形成标准化和系列化。但是,每种联接均存在一定的缺点和局限性,因而,不断补充、完善、发展和改造它们非常必要。今介绍一种新型键联接,它已在产品中得到应用,具有特殊的实用价值。建议将它纳入相应标准中。 At present, the mechanical engineering design at home and abroad are widely used in the connection of the threaded connection, key, pin connection, spline connection, interference connection, rivet connection, and has become standardized and serialized. However, there are some shortcomings and limitations in each type of connection. Therefore, it is necessary to continuously supplement, perfect, develop and transform them. Now introduce a new type of bond, it has been applied in the product, with special practical value. It is suggested to include it in the appropriate standard.
