Abstract

The invention relates to a transmission error testing device and testing method of a large RV reducer, which is characterized in that: the output shaft of the servo input motor and the input shaft of the torque sensor are connected through a flexible coupling; the tested reducer is installed on the reducer through an adapter plate On the mounting seat, the middle part of the input shaft of the reducer is matched with the input end cover through the bearing support part, the insertion end of the input shaft of the reducer is coaxially connected with the double gear at the input end of the reducer through a tensioner sleeve, and the exposed end of the input shaft of the reducer is The input rigid coupling is coaxially connected with the output shaft of the torque sensor, and the input encoder is directly connected to the input shaft of the reducer; the output disc is fixedly connected with the power output end of the reducer, and the output disc is provided with a raised platform with mounting holes , four screw holes are evenly distributed around the mounting hole, the right end of the output shaft of the reducer is inserted into the mounting hole, and is coaxially fixed with the output disc through four alignment screws; the left end of the output shaft of the reducer is connected to the The output encoder input shaft is coaxially connected. The present invention eliminates or reduces test system errors to the greatest extent.

Description

technical field [0001] The invention belongs to the field of precision machinery testing, and relates to a transmission error testing technology of a large RV reducer, in particular to a transmission error testing device and a testing method of a large RV reducer. Background technique [0002] Due to its high precision, high torque and high reliability, RV reducers are widely used in different intelligent manufacturing fields such as industrial robots and turntables. In order to ensure the high stability of the performance of RV reducer products, it is necessary to focus on the performance of the reducer, and the transmission error is the most critical performance index. However, the RV reducer is a high-precision transmission product, and the error of the test system has a great impact on the entire test performance, especially the large hollow RV reducer, such as 320C. It is necessary to ensure the high rotation accuracy of the input and output ends of the RV reducer, and...
