2、水电站建设工地。本文以煤矿运输为背景，对该工况下要求的 上运机进行设计和计算。而对于实际生产中对带式输送机结构所提出的要求，以 整体结构为前提，对整个上运机中的传动系统和制动系统进行了设计与计算。其 中传动系统的设计，选择电动机减速器作为驱动设备，由电动机通过联轴器、 减速器带动传动滚筒，以摩擦为牵引力传给输送带使其运动并输送物资。而拉紧 装置则选择了液压系统从而对整个装置进行了拉紧，设计了液压系统，而且计算 与选择了主要元器件。 关键词关键词 上运机；输送带；驱动装置；拉紧装置 毕业设计(论文) 3 Abstract The up-transmisstion machine is one k
3、ind of the machines which transport the goods upside,it is also one of the machines that are used most widely. It is widely used in the place of mine and so on. But it requests differently in every part, and this article is to the requests in the industry of the mine. This article briefly introduce
4、the structure and its characteristic of the up-transmission machine, facing the problem of the request of equipment and the request of the driving、tensing 、stopping in the working. The article gives the design and calculation of the drive equipment and the tense equipment, in the design of tense equipment, here we choose the hydraulic system, in order to better the designation. Besides, This article also takes a simple elucidation of the stop equipment and the assistant equipment. This de
