Problems solved by technology
[0004] At present, most RV reducer test devices are performance test devices, which test the transmission accuracy, transmission efficiency, stiffness and other performance of RV reducer, and cannot provide the dusty working environment of RV reducer.
In this case, if a dusty working environment can be constructed to test the transmission accuracy, transmission efficiency, stiffness and other performance of the reducer, it is expected to investigate the reliability and reliability of the RV reducer in the dust environment. Tolerance, however, in the existing technology, such tests are still in the blank

The invention provides a dust-resistant reliability testing device for an RV speed reducer. According to the technical scheme, the sealing box and the two dust boxes are connected into a loop through the pipeline, the motor and the air suction valve are arranged on the pipeline, and circulating airflow is formed in the loop; meanwhile, the dust generator is arranged on the pipeline, the dust is uniformly blown into the sealing box from a horn mouth at the end part of the pipeline after being accelerated twice, and the fan which blows air along the axis of the speed reducer is arranged in the sealing box and is crossed with dust airflow, so that the dust is more uniformly distributed in the sealing box. In addition, a flange with a hollow structure is adopted to install the RV speed reducer, so that the to-be-tested part is fully exposed in a dust environment. The invention provides a uniform and controllable dust working environment for the RV speed reducer, the dust concentration is uniform, and the dust can be recycled. On the basis of effectively constructing a dust working environment, the test of performances such as transmission precision, transmission efficiency and rigidity can be realized, so that the reliability of the RV speed reducer is fully detected.
Description
technical field [0001] The invention relates to the technical field of RV reducers, and at the same time relates to the dust resistance test technology of the reducer, in particular to a reliability test device for the dust resistance of the RV reducer. Background technique [0002] Industrial robots are the most typical mechatronic digital equipment with high added value of technology.
