The invention relates to the technical field of robot deceleration. An inner oblique tooth combining crankshaft type RV decelerator of an industrial robot comprises a left rigid disk and a right rigid disk, a pin-teeth housing, pins, cycloid gears, cycloid parts of a crankshaft, and planet parts comprising a sun gear and a planet gear. The oblique tooth combining crankshaft type RV decelerator is characterized in that the planet shaft is connected to eccentric sleeves so as to form dual eccentric combined crankshafts; sliding zinc-based alloy bearings serve as rotating arm bearings, the encircle of each rotating arm bearing is provided with a spiral oil groove, and the axial length of each rotating arm bearing is 5-10 mm larger than each cycloid gear for; the eccentric sleeves are connected with inner oblique gear pairs of the planet shaft; inner oblique tooth rings are formed by adopting plasticity precision forming and has the function of phase position fine turning; one side of the first eccentric sleeve is closed to a second flexible blocking ring, a spring is arranged between the other side of the first eccentric sleeve and a third flexible blocking ring; and the second eccentric sleeve is placed between a first flexible blocking ring and the second flexible blocking ring on the planet shaft. The inner oblique tooth combining crankshaft type RV decelerator has the beneficial effects that precision of the phrase difference can be guaranteed through the assembly type dual eccentric crankshafts which are assisted by the eccentric sleeves and the inner oblique gear pairs of the planet shaft; the sliding zinc-based alloy bearings can achieve self-lubrication; conventional manufacturing precision is achieved; and the cost is reduced by 60%-75%.
Description
[0001] 【Technical field】 [0002] The invention relates to the technical field of industrial robot reducers. It adopts domestic machine tools, conventional manufacturing precision, and the total hysteresis caused by elastic deformation does not exceed 6 arc min. It is an internal helical gear combined crankshaft type RV reducer for industrial robots. [0003] 【Background technique】 [0004] For more than 20 years, the state has repeatedly issued the 863 plan, hoping that my country's robot machine companies will no longer suffer from the humiliation of expensive Japanese RVs. The good news is that the two research groups of "(2011.1-2012.12) 863 plan" have made major achievements through their efforts. breakthrough: [0005] ① "Tianjin No. 1 863 Research Group" released on May 13, 2014: "National 863 High-precision and High-efficiency Reducer for Industrial Robots jointly developed by Baili Tianxing Transmission Company, Tianjin University, Tianjin Vocational University, Shenyan...
