基于空间定轴齿轮结构与链传动的健身娱乐康复器械机构设计

Mechanism Design of Bodybuilding and Entertainment Rehabilitation Equipment Based on the Spatial Fixed Axis Gear Structure and Chain Drive

本文为解决在社会老龄化加剧以及医疗产业快速发展的背景下健身娱乐康复器械匮乏的问题,提出一种供老年人健身娱乐以及病人康复膝关节的运动器械的设计思路。本文基于空间定轴齿轮系与链传动,对该运动器械的娱乐机构的传动原理以及装配过程进行详细介绍,并对链轮的齿数、中心距等相关参数进行设计与计算分析,并利用Soildworks建立整体的三维模型。最后经力学分析与虚拟示波器采集的数据验证该健身器械在实际工作中的稳定性与结构合理性。经验证该运动器械完全符合老年人健身娱乐以及病人康复膝关节的要求。

In this paper, in order to solve the problem of the lack of fitness and entertainment rehabilitation equipment under the background of the rapid development of the social aging and the rapid de-velopment of the medical industry, this paper puts forward a design idea of sports equipment for the elderly fitness and entertainment and the rehabilitation of patients’ knee joint. In this paper, based on the spatial fixed axis gear train and chain drive, the transmission principle and assembly process of the entertainment mechanism of the sports equipment are introduced in detail, and the related parameters such as the number of teeth and center distance of the sprocket are designed and calculated, and the overall three-dimensional model is established by using Solid Works. Fi-nally, through the mechanical analysis and the data collected by virtual oscilloscope, the stability and structural rationality of the fitness equipment in practical work are verified. It has been veri-fied that the equipment fully meets the requirements of fitness and entertainment for the elderly and rehabilitation of knee joint of patients.
