The mechanical transmission mechanism provided by the invention is reasonable in design, light in weight, optimized in structure, integrated in circuit, convenient to install, low in cost and high in precision, aluminum alloy materials are selected, the weight of the mechanism is greatly reduced, a precise timing synchronizing belt is selected, and the transmission precision is higher than that of an original mechanism chain and common synchronizing belt transmission.
Description
technical field [0001] The invention relates to the technical field of transmission mechanisms, in particular to a mechanical transmission mechanism of a cardiopulmonary endurance tester. Background technique [0002] A lung function tester is a medical device used to measure the volume of air inhaled and exhaled by the lungs. It can perform lung function tests and track lung health, and can measure commonly used lung function testing parameters including FVC, FEV1, FEV1 / FVC, etc. [0003] At present, the transmission mechanism of some cardiopulmonary endurance testers: the electromagnetic wheel and the splicing frame are two independent components. The problem of this mechanism is that it is heavy, complicated to manufacture, high in cost, cumbersome to install, and inconvenient to maintain. Therefore, we propose a The mechanical transmission mechanism of the cardiopulmonary endurance tester is used to solve the above problems. Contents of the invention [0004] The pur...
