Design of shell crane in CVT transmission

Abstract：The shell crane in CVT transmission is a kind of lifting equipment which uses a single column and a rotating arm to lift goods. The lower end of the shell crane in CVT transmission is generally fixed on the basis of concrete. The slewing arm can be rotated according to the needs of the customer. The shell crane in the CVT transmission is a kind of lifting equipment which uses a single column and the rotating arm to lift the cargo. The lower end of the shell crane in the CVT transmission is generally fixed in the On the basis of concrete, The slewing arm can be rotated according to the customer’s needs. The shell crane of CVT transmission is simple in structure, convenient in operation and large in working space. It is widely used in various factories. Mine workshop production line and assembly line, is an energy-saving and efficient material hoisting equipment. In recent years, with the development of the strength of our country, all kinds of industries have made great progress. In the port transportation, the transportation machinery with the shell crane as the main working unit in the CVT transmission is becoming more and more important. And the design of the rotary part is paid more and more attention. The influence of the rotary part on its overall performance is self-evident. Therefore, it is necessary to discuss the design of the rotary mechanism. Taking the middle shell crane of CVT transmission as an example, the middle shell of CVT transmission is described in this paper. The general process of the general design of the body crane and the preliminary design of its rotary mechanism are given, and the CAD drawings of the rotary mechanism and its overall system are given, and the conclusion is proved. The parameters of the shell crane in the CVT transmission can be checked by the stability of the whole machine and the motor and bearing selected by the rotary mechanism can meet the requirements. This article draws lessons from the previous experience of scholars, but also can provide some reference for later learning.
