济南导轨升降货梯http://www.jntr168.com/的机械部分主要包括升降装置、轨道装置和换带装置三部分,其中升降装置主要用来悬吊被升降者,是整个机构的最核心部分,轨道装置的作用主要是提供移动轨迹,使运行更加畅通,换带装置是当升降货梯要过门时用来切换轨道之用。升降装置升降装置的内部结构主要由齿轮机构、支 架、蜗轮蜗杆、导向机构、吊臂、上、下壳等组成。齿轮机构齿轮机构主要包括大、小齿轮、缠带轮、中轴以及由止动扣、扭簧组成的保险装置。
Jinan rail cargo lifter mechanical part consists of three parts of the lifting device, track unit and change tape device, wherein the lifting device is mainly used to lift the suspension, was the most crucial part of the whole organization, the role of rail unit is to provide a mobile track that run more smooth, change belt device is going to get married when the cargo lifter for switching orbit. Internal structure of the lifting device the lifting device is mainly composed of a gear mechanism, the bracket, the worm, the guide body, the arm, the upper and lower casing components.Gear mechanism gear mechanism including large and small gear, wrapped around a pulley, the central axis and the stopper buckle, safety device consisting of a torsion spring.
选用闭式齿轮传动,大、小齿轮均选用钢,经调质处理,属于软齿面,由于闭式软齿面齿轮传动常见的失效形式为齿面点蚀,故设计时按齿面接触疲劳强度计算,按齿根弯曲疲劳强度进行校核。支架支架用于固定、支承升降货梯箱体内部所有的机械零件和部分电器元件,主要由侧板、连接管和连接片等零件焊接而成,材料均选 用,其中两侧板的厚度,同时为了减轻支架的重量,在两侧板上设计了很多工艺孔。蜗轮蜗杆由于蜗轮蜗杆机构具有传动比大、结构紧凑、冲击载荷小、传动平稳和 噪声低等优点,并具有反向自锁的特性。可以保证搬运患者过程中,电动机断电时传动机构能够自锁,故选用蜗轮蜗杆减速器。采用渐开线蜗杆,材料为钢,对其螺 旋面进行淬火处理,以提高传动效率和增加耐磨性,蜗轮材料选用聚甲醛。塑料蜗轮具有加工经济性好、传动平稳、吸振降噪、质量轻、耐磨和自润滑等优点,使得 升降货梯的设计更加人性化。
Selection of enclosed gear drives, large and small gears are made of steel, after quenching, are soft tooth surface, due to the closed soft tooth surface gear common failure mode for the tooth surface pitting, so by the time the tooth surface contact fatigue design strength calculation, according to the tooth root bending fatigue strength to be checked. Bracket Bracket for fixing,supporting cargo lift all the mechanical parts inside the box and some electrical components, mainly by side, connecting pipes and welded parts such as connecting pieces, materials are selected,the thickness of which both sides of the plate, and in order reduce the weight of the stent, on both sides of the board designed a lot of craft holes. Since the worm worm mechanism having a transmission ratio, compact, impact load is small, smooth transmission and low noise advantages, and has a reverse self-locking feature. You can ensure that the process handling patients, when the motor is de-energized transmission mechanism can be self-locking, so the selection of worm gear reducer. Involute worm, materials for steel, quenching its helical surface, in order to improve transmission efficiency and increase wear resistance, worm material selection POM. Plastic Worm has processed the economy is good, smooth transmission, absorbing vibration noise, light weight,wear-resistant and self-lubricating, etc., so that cargo lifter design more humane.
升降货梯http://www.jntr168.com/导向机构主要由导向塑料管、导向支架、压缩弹簧、安全塞、导向外壳和导向轴等零件组成,为导向机构的半剖视,两个导向塑料管之间形成一个窄缝,升 降布带从这个窄缝中伸出箱体,防止布带卷乱,起到导向的作用。安全塞由导向支架和压缩弹簧支承,为了防止压缩弹簧受力后失去稳定性,在安全塞上设计了一个 小导杆,小导杆与弹簧间的间隙参照表进行设计。吊臂轴焊接而成,两端分别安装一个吊臂挂钩,材料选用,进行调质处理,与箱体下壳的挂钩一起构成三个悬吊 点,通过软支承吊具将被升降者吊起,吊臂的承重量,为了使被升降者在乘坐时能够处于舒适状态,两吊臂挂钩间距参照表列出了水平尺寸的相关数据作为设计参考,平衡杆用来保持升降装置的平衡,材料设计成空心管状,减轻了吊臂整体的重量。
Guiding mechanism mainly consists of a plastic tube guide, guide bracket, compression springs, safety plug, guide housing and the guide shafts and other parts for the semi-sectional view of the guide mechanism is formed between the two guide a narrow plastic tube, lifting the cloth belt from this narrow protrude box, cloth strap to prevent chaos, play a guiding role. Safety plug from the guide bracket and the compression spring is supported, in order to prevent the destabilization of the force of the compression spring, the safety plug is designed in a small guide bar, a small gap between the guide bar and the spring is designed with reference to the table. Boom shaft welded ends were to install a crane hook, material selection, quenching and tempering treatment, with the hook under the shell casing together constitute the three suspension points, supported by soft lift spreader who will be lifted , bearing the weight of the boom, in order to be able to lift those at the ride in a comfortable state, two crane hook spacing data reference table lists the horizontal dimension as a design reference, balance bar lifting device used to maintain balance, materials designed as a hollow tube, to reduce the overall weight of the boom.
