Abstract

The invention provides an improved type screw nut. The screw nut comprises a left screw unit, a right screw unit, a fixing sleeve and nut units. The left screw unit is connected with the right screw unit via the fixing sleeve; the left screw unit is identical with the right screw unit in structure, except that threads arranged thereon are in opposite twisting directions; and the nut units are mounted, in spiral connection, on the left screw unit and the right screw unit respectively. The screw nut can solve the problems that in application of existing ball screws, the assembling clearance between a nut and a screw causes a screw nut to sway and abrade upper teeth of the screw in the using process, most of existing screw nuts are of an integral structure, the screw nuts driven to a specificposition on the screw are difficult to fix, and the application of the nuts is affected.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to an improved lead screw nut. Background technique [0002] The ball screw is a kind of screw nut. The ball screw on the market is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into shaft Repeated force in the direction, at the same time, it has the characteristics of high precision, reversibility and high efficiency. Due to its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments. [0003] During the use of the existing ball screw, the assembly gap between the nut and the screw still exists, causing the screw nut to shake during use and causing wear to the upper teeth of the screw, and the existing Most of the nuts are integral structures; the nuts are difficult to fix when they are driven to...
