摘要
Abstract
The lifting conveyor will produce the inertia force during the starting and braking process,which is applied to the lead screw lift as the horizontal load,so that the extreme value of the stress of the rolling lead screw in the lead screw lift rises by a large margin.The virtual prototype model for the lifting conveyor is built by ADAMS to perform dynamic prop-erty analysis for the starting and braking process in order to work out the change rule of start-stop time to the dynamic be-havior.The guiding support wheel mechanism is put forward to reduce the stress extreme value of the screw lift.It's indicated that the guiding support wheel can be used to facilitate to support the extending end of the screw lift,to significantly im-prove the load-carrying condition and decrease the stress extreme value,which can provide reference for extending the serv-ice life of the lift and advancing its working reliability.关键词
