2．0型卷揚機設計
摘 要
本設計是一種建筑起重機械，用來提升物料、安裝設備等作業(yè)，由機械動力驅動卷筒、卷繞繩索來完成牽引工作的裝置。本設計采用了新型的制動電機，節(jié)省了制動器，使得結構更加緊湊。其主要結構組成還有，減速、聯軸器、卷筒等。
動力傳動部分主要有傳動方案的設計、原始數據的計算、電動機的選擇、減速器的選擇、動力方案的選擇和強度校核。其中主要是傳動方案的設計和卷筒的結構設計。本設計的步驟是從鋼絲繩開始入手，然后依次對卷揚機的、電動機、減速器、制動器、聯軸器設計與選取。其中卷筒結構、卷筒軸、卷筒轂的設計與校核最為主要，本設計重點做了介紹，其余部分有得只是略作分析。
關鍵詞：卷揚機，制動電機，聯軸器，卷筒
THE DESIGN OF 2.0 CONSTRUCTION WINCHES
ABSTRACT
The design is called construction winches, which is used to lift materials, to install the operation equipments .It is driven by mechanical power motor and by the winding rope device to complete the work. This design uses a new type of brake motor so as to save the brake, so the structure becomes more compact. The rest of the machine are reducer, coupling, reel and so on.
The part of power transmission includes the design of the transmission, the calculation of initial data, the selection of motor reducer and power options .In the end it is strength check. This design of hoist starts from the wire rope, and next then turn on the winch reel, reel spindle, motor, gear reducer, speed reducer shaft, brakes, couplings and pulley reel machine-oriented design . The key is the structure design of the winch reel. The analysis of the rest are relatively simple.
KEY WORDS: winch,motor,coupling,reel
