Description
Technical field
The utility model relates to the rotation of speed reducer and the optimization of non-rotatable member, particularly relates to a kind of Light Aluminum Alloy structure RV speed reducer.
Background technique
Robot RV reducer since it in 1986 come out since, as robot a kind of new gear retarder and obtain extensive use.But robot RV reducer major part applied in the market is external import, housing, rigid disk and output disc material are alloyed steel.Because speed reducer pinwheel housing, rigid disk, output disc adopt alloy steel matrix, cause processing difficulties, overall weight is large, especially when axle or bearing and these parts generation serious frictions, then needs above-mentioned parts entirety to change; And alloyed steel overall weight is large, very easily causes robot to bear a heavy burden large, be unfavorable for robot lightweight, miniaturization on the one hand, also add the maintaining cost in later stage on the other hand, seriously constrain the development of robot of China and equipment industry.
Summary of the invention
The utility model provides a kind of Light Aluminum Alloy structure RV speed reducer, solve that existing RV speed reducer weight is large, work time noise large, the problem such as difficulty of processing is large.
The utility model is achieved through the following technical solutions:
A kind of Light Aluminum Alloy structure RV speed reducer, comprise pinwheel shell 16, rigid disk 15 and output disc 17, alloyed steel pin wheel housing 8, described alloyed steel pin wheel housing 8 is arranged on inside pinwheel shell 16, and alloyed steel pin wheel housing 8 side is rotatably connected to rigid disk 13, and opposite side is rotatably connected to output disc 17; Described pin wheel housing 8 is arranged on inside pinwheel shell 16 so that interference is chimeric, and the body of described pinwheel shell 16, rigid disk 15 and output disc 17 is pack alloy matrix.
The pack alloy matrix of described rigid disk 15, pinwheel shell 16 and output disc 17 is chimeric with between each rotatingshaft alloyed steel axle sleeve 18.
Described rigid disk 15 is ring-type or netted hollow structure with the pack alloy matrix of output disc 17.
Silencing and damping material 7 is embedded by spraying or extruding in described hollow structure.
The intimate surface cover of described rigid disk 15 and output disc 17 has one deck alloyed steel surface layer.
The utility model, relative to prior art, has following advantage and effect:
The utility model, by the pinwheel shell of existing speed reducer alloyed steel material, rigid disk and output disc, changes pack alloy matrix into, this improvement, effectively alleviate the weight of RV speed reducer, overcome because alloy steel matrix hardness is high, cause processing difficulties, robot is from great problem.
Pin wheel housing is arranged on inside pinwheel shell in the mode that interference is chimeric by the utility model, effectively improves pinwheel inwall wear-resisting property and hardness, alleviates pinwheel containment weight while having high strength.
The utility model by chimeric with between each rotatingshaft for the pack alloy matrix of rigid disk, pinwheel shell and output disc alloyed steel axle sleeve, make axle or bearing directly and the pack alloy matrix of rigid disk, pinwheel shell and output disc rub; This improvement, both ensure that the lightweight of rigid disk, pinwheel shell and output disc, again owing to adding alloyed steel axle sleeve, ensure that its wear-resisting property is constant, and when axle or bearing and the generation heavy wear of alloyed steel axle sleeve, only need to change axle sleeve, without the need to rigid disk, pinwheel shell or output disc entirety just being changed, greatly reduce later maintenance cost, improve working efficiency.
The pack alloy matrix of rigid disk and output disc is adopted part cyclic or netted hollow structure by the utility model, further mitigates the own wt of matrix.
