Contact Force Analysis of RV Reducer

2018 6th International Conference on Mechanical, Automotive and Materials Engineering (CMAME), 2018
RV reducer is a commonly used transmission device in the industrial robot system. It incorporates two stage drive; the first stage uses involute planetary gear and the second stage uses cycloidal pin wheel. Due to the high working intensity and long working time of the robots, more and more attention has been paid to the stress analysis of all parts of

The SGLT2i Dapagliflozin Reduces RV Mass Independent of Changes in RV Pressure Induced by Pulmonary Artery Banding

Cardiovascular Drugs and Therapy, 2022
Sodium glucose linked transporter 2 (SGLT2) inhibition not only reduces morbidity and mortality in patients with diagnosed heart failure but also prevents the development of heart failure hospitalization in those at risk. While studies to date have focused on the role of SGLT2 inhibition in left ventricular failure, whether this drug class is ...

RV Reducer Backlash Analysis Based on Robust Design

Applied Mechanics and Materials, 2011
The RV reducer backlash is well controlled by means of robust design. Some factors influencing backlash are analyzed and divided into controllable factors and uncontrollable (noise) factors. The requirements for experimental factors are met for robust design. The experiment analysis is proposed by using orthogonal experiment and G.Taguchi robust design
