Abstract

This design is the design of machine design of the lifting nut. Here mainly include: rack system design, chain drive system design, system design, adjustment mechanism design. The graduation design on the design of the basic skills training, improve the analysis and the ability to solve engineering problems, and created certain conditions for general mechanical design.
The structure is mainly composed of the motor power will need to transfer the power of the driving device through the coupling, chain wheel sprocket, so as to drive the movement, the nut lifting machine but also show its superiority, there are broad prospects for the development.
The content of this paper:
(1) the overall structure design of the lifting nut machine.
(2) performance analysis machine lifting nut.
(3) the choice of motor.
(4) enhance the nut transmission system, machine component design.
(5) the design of parts design calculation and check.
(6) drawing machine assembly and important parts assembly drawings and parts drawings design.
Keywords: nut hoist, coupling, ball screw
