Driving nut

Abstract

The invention discloses a driving nut, comprising a base and a driving nut body. The driving nut body includes an outer sleeve body and an neck bush. The outer sleeve body is provided with left-hand threads inside and is welded on the base. The neck bush is made of aluminum bronze materials, wherein outer surface of the neck bush is equipped with threads that can be used cooperatively with the left-hand threads so that the neck bush is connected in the outer sleeve body, and inner wall of the neck bush is equipped with right-hand threads. The structure and a processing method of the driving nut in the invention are simple. The driving nut body adopts a separated-structure design, wherein the outer sleeve body and the neck bush are connected through the left-hand threads and inside the neck bush is right-hand thread, thereby avoiding that between the outer sleeve body and the neck bush get loosen during a driving process of the driving nut, and instead improving fixing abilities of the driving nut. The inner lining sleeve is made of aluminum bronze materials while the outer sleeve body is made of ordinary cast iron materials, which substantially improves plastic and tensile strengths, saves production cost, and prolongs service life of the driving nut at the same time.

Description

technical field [0001] The invention relates to a nut, in particular to a drive nut. Background technique [0002] The transmission nut and the base widely used at present is an integral structure (as attached figure 1 As shown), the overall material is made of cast iron. The transmission nut of this structure is relatively brittle, and will burst after long-term use. The service life is relatively short, making the machine unable to work normally. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a drive nut with a split structure with good shape and strength. [0004] The technical solution of the present invention is achieved as follows: a drive nut, including a base and a nut body, the nut body includes an outer body and an inner bush; the outer body is provided with a left-hand thread; the outer surface of the inner bush is The upper part is connected to the outer body through a th...
