Abstract

The invention relates to an RV speed reducer, in particular to an RV speed reducer with a reversing function. The RV speed reducer comprises a pin gear housing and an RV speed reduction mechanism mounted in the pin gear housing and further comprises a revering mechanism. The revering mechanism comprises a mounting seat, a first input shaft, a first bevel gear and a second bevel gear. The mountingseat is fixedly connected with the pin gear housing, and the first input shaft is perpendicular to a power input shaft of the RV speed reduction mechanism and is mounted on the mounting seat in an inserted mode. The first bevel gear is mounted on the power input shaft of the RV speed reduction mechanism, and the second bevel gear is mounted on the first input shaft. The first bevel gear and the second bevel gear are engaged. The RV speed reducer is characterized in that the structure is compact, the size is small, the bearing capacity is high, the life is long, and horizontal movement can be converted into vertical movement.

Description

technical field [0001] The invention relates to a speed reducer, in particular to an RV speed reducer with reversing function. Background technique [0002] RV transmission is a new type of transmission developed on the basis of cycloidal pinwheel transmission. It uses a shared crank shaft and a central disc support structure to form a closed differential transmission, which has a series of advantages such as small size, light weight, large transmission ratio range, and high transmission efficiency. Compared with simple cycloid planetary transmission It has smaller volume and greater overload capacity, and the rigidity of the output shaft is large. At present, in the joint transmission of industrial robots, RV reducers have gradually replaced harmonic reducers. [0003] However, the ordinary RV reducer realizes a kind of parallel shaft motion transmission, that is, the output shaft of the reducer is coaxial or parallel to the input shaft. However, in some applications, no...
