Problems solved by technology

[0003] However, the screw and the nut in the current factory cannot be separated freely, and the nut needs to be cut into two halves from the axial direction for half-nut transmission
Moreover, the screw and the copper nut in the clutch-type screw mechanism are in direct contact and friction, resulting in high wear and short life, requiring regular replacement of the nut, which seriously affects production efficiency

Abstract

The invention discloses a half nut assembly, which comprises a half nut, a roller, and a fixing unit. The roller is mounted on the half nut through the fixing unit; the inner surface of the half nut is provided with a rolling groove, and the roller Roll along the roll groove. Through the mutual cooperation between the rolling groove and the roller arranged on the inner surface of the half nut, the sliding friction is changed into rolling friction, the loss of the nut is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical design, in particular to a half nut assembly. Background technique [0002] In order to achieve accurate handling and transmission of objects, electrical equipment generally uses screw and nut components to control the rotation of the screw through the motor, convert the rotation of the motor into the linear motion of the nut, and connect the stage to the nut to achieve accurate control of the motor Linear displacement such as translation and lifting of the stage. [0003] However, the screw and the nut in the current factory cannot be separated freely, and the nut needs to be cut into two halves from the axial direction for half-nut transmission. Moreover, the screw rod and the copper nut in the clutch type screw mechanism are in direct contact and friction, which results in large wear and short life, and the nut needs to be replaced regularly, which seriously affects the production efficienc...
