The hollow reduction box special for the arc welding robot comprises a dual-eccentricity input shaft, flower basket holders, a cylinder needle, a needle wheel, cycloidal gears, a fixed locating pin, an inner hexagon screw, an input end flange and an output end flange, the dual-eccentricity input shaft is of a hollow structure, two flower basket holders are installed on the dual-eccentricity input shaft, the two cycloidal gears are installed on the outsides of the two flower basket holders, the outsides of the cycloidal gears are in rolling contact with the insides of the cylinder needle and the needle wheel, and the fixed locating pin enables the input end flange and the output end flange to be fixed together through the inner hexagon screw. The hollow reduction box special for the arc welding robot has the advantages of being scientific in design, reasonable in structure, big in torsional rigidity, big in transmission ratio, high in kinematic accuracy, small in return difference, small in starting inertia, strong in shock resistance, high in transmission efficiency and the like.
Description
Technical field
The utility model relates to arc welding robot hollow speed reducer technical field, be specially the special-purpose hollow speed reducer of arc welding robot.
Technical background
Existing arc welding robot drive mechanism is to adopt planet to add cycloid speed reducer mostly, gas protects the welding gun silk feeding tube and carbon dioxide conduit uses the external gas that is connected to protect on the welding gun usually, therefore in actual use, on the one hand because gas is protected welding gun silk feeding tube and the external potential safety hazard that exists of carbon dioxide conduit, on the other hand because gas is protected the welding gun silk feeding tube and carbon dioxide conduit is external so that restriction is received in arc welding robot overall space position.
Summary of the invention
The purpose of this utility model is, provides a kind of arc welding robot gas that solves to protect welding gun silk feeding tube and the external special-purpose hollow speed reducer of arc welding robot of carbon dioxide conduit, has changed the conventional construction pattern.
Technical solution of the present utility model: the special-purpose hollow speed reducer of arc welding robot, comprise two eccentric input shafts, gaily decorated basket retainer, cylindrical needle,, pinwheel, cycloid wheel, fixed locating stud, socket head screw, input end flange, output terminal flange, two eccentric input shafts are hollow structure, at two eccentric input shafts two gaily decorated basket retainers are housed, two cycloid wheel are installed in two gaily decorated basket retainer outsides, form rolling between the cycloid wheel outside and cylindrical needle, the pinwheel inboard and contact, fixed locating stud is fixed together input flange, output flange by socket head screw.
Described two eccentric input shaft is connected an end with the power of actuating motor and is provided with screw hole.
Described gaily decorated basket retainer is nylon cages, simultaneously uniform cylindrical roller.
Angular contact ball bearing is equipped with at described input flange, output flange two ends respectively correspondence, and is provided with end ring, in the angular contact ball bearing outside corresponding TTO seal ring is housed.
Described fixed locating stud one end is equipped with nylon stopper.
The special-purpose hollow speed reducer of the utility model arc welding robot has design science, rational in infrastructure, has that torsional stiffness is large, velocity ratio is large, kinematic accuracy is high, return difference is little, starts that inertia is little, strong shock resistance and transmission efficiency advantages of higher.

Embodiment
Below in conjunction with the drawings and specific embodiments concrete structure of the present invention is elaborated.
As shown in Figure 1, two eccentric input shafts 1 are hollow structure, two eccentric input shafts 1 are provided with screw hole 11 with the power of actuating motor by an end and are connected, at two eccentric input shafts 1 two gaily decorated basket retainers 2 are housed, gaily decorated basket retainer 2 is nylon cages, uniform cylindrical roller 21 of while, eccentric 180 degree of gaily decorated basket retainer 2 coaxial-symmetricals, guarantee to do multiple tooth engagement between two cycloid wheel 5 and the pinwheel 4, guaranteed the highi degree of accuracy transmission, utilize simultaneously two eccentric input shaft 1 as bearing inner race, cycloid wheel 5 endoporus have solved the miniaturization of the special-purpose hollow speed reducer of arc welding robot as bearing outer ring; Two cycloid wheel 5 are installed in two gaily decorated basket retainer 2 outsides, forming between cycloid wheel 5 outsides and cylindrical needle 3, pinwheel 4 inboards rolls contacts, fixed locating stud 6 is fixed together input flange 7, output flange 8 by socket head screw 9, fixed locating stud 6 one ends are equipped with nylon stopper 10, because pinwheel 4 maintains static, in this case, cycloid wheel 5 is done differential teeth planetary motion, by fixed locating stud 6 with transmission of power to output terminal flange 8; Angular contact ball bearing A71, angular contact ball bearing B81 are equipped with in input flange 7, output flange 8 two ends respectively correspondence, and be provided with end ring 83, in angular contact ball bearing A71, the angular contact ball bearing B81 outside corresponding TTO seal ring A72, TTO seal ring B82 are housed, prevent the outer benefit of lubricant oil;
Owing to adopting the two eccentric input shaft structures of hollow, the pipeline that gas is protected welding gun can pass speed reducer fully, and realizes that the pipeline of gas guarantor welding gun is fully built-in.
