Problems solved by technology

The integrally formed crank shaft is used in the RV reducer, which has the following technical problems: 1. Due to the complicated structure of the crank shaft, the processing of the crank shaft is difficult and the processing cost is high, mainly because the eccentricity accuracy is high, and in In the early stage of processing, the crank is processed by forging or casting blanks, and it is difficult to ensure the eccentricity of the crank shaft; 2. After the RV reducer is used for a long time, if the crank shaft wears and other problems, the entire shaft will be scrapped , resulting in the scrapping of the entire product, poor economic applicability

Abstract

The invention discloses an eccentric shaft assembly for a recreational vehicle (RV) reducer. The eccentric shaft assembly is easy to machine and convenient to replace and comprises a main shaft. An outer spline is arranged on the periphery of the main shaft which is connected with a first eccentric wheel and a second eccentric wheel through splines. An eccentric wheel gasket is arranged between the first eccentric wheel and the second eccentric wheel. One end face of the eccentric wheel gasket abuts against the first eccentric wheel. The other end face of the eccentric wheel gasket abuts against the second eccentric wheel. The main shaft is further provided with a first annular groove and a second annular groove. A first clamp spring is arranged in the first annular groove and abuts against the end face of the first eccentric wheel. A second clamp spring is arranged in the second annular groove and abuts against the end face of the second eccentric wheel. The main shaft is sleeved with a first bearing and a second bearing. One end face of the first bearing abuts against the first clamp spring, and one end face of the second bearing abuts against the second clamp spring.

Description

technical field [0001] The invention relates to reducer technology, in particular to an eccentric shaft of an RV reducer. Background technique [0002] RV reducer has the advantages of small size, light weight, large transmission ratio range, long life, stable precision, high efficiency, stable transmission, etc. It is widely used in industrial robots, machine tools, medical testing equipment, satellite receiving systems and other fields. The RV reducer adopts two-stage deceleration. The first stage deceleration adopts involute cylindrical gear planetary deceleration. The active sun gear is connected with the input shaft. If the sun gear rotates clockwise, it will drive the planetary gears evenly distributed along its circumference to circle the sun. While the center of the wheel axis is revolving, it is self-propagating counterclockwise. Each planetary wheel is fixedly connected to its respective crankshaft, so that the crankshaft rotates at the same speed, and the cranksha...
