大型游乐设施，是指用于经营目的，承载乘客游乐的设施，其范围规定为设计最大运行线速度大于或者等于2m/s，或者运行高度距地面高于或者等于2m的载人大型游乐设施。为满足乘客追求惊险刺激的心理，现代大型游乐设施的运动方式、运行加速度等技术指标日趋复杂和提高，而销轴是大型游乐设施中非常重要的零部件，是用来承受大型游乐设施因剧烈运动而产生的各种复杂应力和冲击载荷的重要零件，如大型游乐设施中的座舱吊挂销轴、传动齿轮、整机运行主轴等。而这些销轴一旦因设计强度不足而发生严重变形甚至断裂，则会产生严重的事故。近年来国内发生的几起大型游乐设施重大伤亡事故，多与机械销轴失效有关。因此大型游乐设施重要销轴的设计应考虑多方面因素和要求，其中主要问题是销轴的选材、结构、强度和刚度。其中对于销轴的强度校核尤为重要，通过校核来确定销轴的设计是否能达到使用要求。
大型遊樂設施，是指用于經營目的，承載乘客遊樂的設施，其範圍規定為設計最大運行線速度大于或者等于2m/s，或者運行高度距地麵高于或者等于2m的載人大型遊樂設施。為滿足乘客追求驚險刺激的心理，現代大型遊樂設施的運動方式、運行加速度等技術指標日趨複雜和提高，而銷軸是大型遊樂設施中非常重要的零部件，是用來承受大型遊樂設施因劇烈運動而產生的各種複雜應力和遲擊載荷的重要零件，如大型遊樂設施中的座艙弔掛銷軸、傳動齒輪、整機運行主軸等。而這些銷軸一旦因設計彊度不足而髮生嚴重變形甚至斷裂，則會產生嚴重的事故。近年來國內髮生的幾起大型遊樂設施重大傷亡事故，多與機械銷軸失效有關。因此大型遊樂設施重要銷軸的設計應攷慮多方麵因素和要求，其中主要問題是銷軸的選材、結構、彊度和剛度。其中對于銷軸的彊度校覈尤為重要，通過校覈來確定銷軸的設計是否能達到使用要求。

Large recreation facilities is used for business purposes,carrying passengers and recreation facilities,the scope of the provisions for the design maximum speed is greater than or equal to 2m / s, or run the height from the ground is higher than or equal to 2m manned large recreational facilities.In order to meet passenger's pursuit of the thrills of psychology,modern large-scale recreational facilities of the motion,acceleration of technical index is becoming more and more complicated and improve the pin is large recreation facilities are very important parts, is used to bear the impact load is the important part of large recreation facilities for extreme sports of all kinds of complicated stress,such as large-scale recreational facilities in the cabin hanging pin shaft,gear transmission,operation of the machine spindle. However, when the shaft is due to the design strength of the problem and the occurrence of severe deformation or even rupture,it will have a serious accident.In recent years,several major recreational facilities occurred in the major casualties,many and mechanical pin axis failure related.Therefore, the design of the important pin axis of large amusement facilities should consider many factors and requirements, and the main problem is the selection,structure,strength and rigidity of the pin axis..The strength of the pin axis is particularly important,through checking to determine whether the design of the pin shaft can meet the use requirements..
