Abstract
This design is the design of convex hoist. Here mainly includes: the design of convex hoist transmission system. 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 to generate power through the coupling will need to transfer the power to the screw, screw through screw material movement will move a certain position, the boss hoist demonstrates its superiority, there are broad prospects for the development.
The content of this paper:
(1) the overall structure design of lifting lug machine.
(2) the boss hoist performance analysis.
(3) the choice of motor.
(4) the boss lifting transmission system, machine component design.
(5) the design of parts design calculation and check.
(6) parametric design
(7) drawing machine assembly and important parts assembly drawings and parts drawings design.
Key Words: boss hoist; continuous transportation machines; parametric design
