Description
Technical field
The invention belongs to retarder technical field, relate in particular to a kind of bearing type RV retarder.
Background technique
At present, conventional robot RV retarder comprises pin wheel housing, this pin wheel housing is provided with the planet carrier two monomers being formed by connecting by connecting element, between two monomers, be provided with two cycloid wheel, equal annular array and the corresponding bearing position that is provided with three tapered roller bearings on two monomers, on the bearing position of three groups of corresponding settings, be equipped with the crankshaft being connected with power plant, each crankshaft is all through the circular hole in two cycloid wheel.Adopt the RV of the robot retarder of this structure first power plant (sun gear) to be reached simultaneously on (planet wheel) of three crankshafts, crankshaft drives two cycloid wheel runnings, and cycloid wheel reaches pin wheel housing by power and realizes double reduction output.
But can there is following shortcoming in the RV of the robot retarder of this structure:
(1) because there are three crankshafts (being power input shaft) to carry out transmission, three crankshafts all support on the bearing position of the tapered roller bearing of planet carrier by tapered roller bearing, therefore on crankshaft, the axial precision of tapered roller bearing bearing position and radial accuracy require all very strict, on crankshaft, two eccentric wheels are suitable with cycloid wheel respectively, to two eccentric circularity, cylindricity, phase difference requires very strict, planet wheel also will be installed by spline in the end of crankshaft, to the phase difference between spline and eccentric wheel, require very strict, these dimensional chains have increased the difficulty of processing of crankshaft greatly, manufacture cost is high, and the assembly precision of crankshaft is also had to very high requirement,
(2) in use, tapered roller bearing easily weares and teares, and causes quality of fit to reduce, reliability variation, and then reduce working life.
Summary of the invention
The object of the embodiment of the present invention is to provide a kind of bearing type RV retarder, the RV of the robot retarder providing with solution prior art needs three power input shafts bearing position by tapered roller bearing on planet carrier to support the action edge transmission of going forward side by side, manufacture cost is high, and tapered roller bearing easily weares and teares, cause quality of fit to reduce, reliability variation, and then the problem that transmission accuracy reduces and reduce working life.
For solving the problems of the technologies described above, the technological scheme of the embodiment of the present invention is: bearing type RV retarder, comprise pin wheel housing, in described pin wheel housing, be rotatablely equipped with scaffold, described scaffold is provided with two cycloid wheel that are in transmission connection by needle roller and described pin wheel housing, on described scaffold, be rotatablely equipped with a power input shaft, the power intake of described power input shaft stretches out described scaffold, described power input shaft is provided with two driving eccentric wheels, and two described driving eccentric wheels are respectively through the center of two described cycloid wheel and suitable with corresponding described cycloid wheel; On described scaffold, be rotatablely equipped with at least two positioning shafts, described in two, positioning shaft is symmetrical arranged with respect to the gyration center of described power input shaft, described in each, on positioning shaft, be equipped with two transmission eccentric wheels, two described transmission eccentric wheels are respectively through two described cycloid wheel and suitable with corresponding described cycloid wheel.
As a kind of improvement, described in two, the gyration center of positioning shaft and the gyration center of described power input shaft are located along the same line.
As further improvement, described in two, positioning shaft is all rotated and is installed on described scaffold by roller bearing.
As a kind of improvement, described power input shaft is rotated and is installed on described scaffold by tapered roller bearing.
As further improving, the power intake of described power input shaft is provided with spline.
As a kind of improvement, the eccentric diameter of described driving is greater than the eccentric diameter of described transmission.
Owing to having adopted technique scheme, the beneficial effect of the embodiment of the present invention is:
Owing to being rotatablely equipped with two driving eccentric wheels that a power input shaft and power input shaft be provided with on scaffold respectively through the center of two cycloid wheel, thereby power is inputted from power input shaft, by two driving eccentric wheels on power input shaft, drive two cycloid wheel to move, be aided with two positioning shafts simultaneously and position and provide inertia force, final two cycloid wheel actions drive pin wheel housing action and the power after slowing down are exported.Adopting this bearing type RV retarder to realize power inputs and reaches primary speed-down from power input shaft (central shaft), with respect to conventional machines people RV retarder, use and sun gear that this bearing type RV retarder has reduced power input shaft number coordinate the use of planet wheel, thereby have reduced manufacture cost; Number minimizing due to power input shaft, thereby drive the quality of fit of eccentric wheel and cycloid wheel easily to guarantee, reliable transmission improves and is convenient to processing and installs, when having reduced a plurality of power input shafts simultaneously and having existed simultaneously to the eccentric circularity of two drivings, cylindricity, the high-precision requirement of phase difference and the assembling difficulty of planet wheel and the difficulty of manufacturing.Adopt in sum this bearing type RV retarder difficulty of processing low, and be convenient to assembling, reliable transmission and precision effectively improve, and have increased working life, have solved that a plurality of power input shafts exist simultaneously and the Size Chain that causes processing and assembly precision difficulty increase that forms.
The effect of playing due to positioning shaft is that two cycloid wheel are coupled together, and power is passed to pin wheel housing by cycloid wheel, so transmission of power direction is along cycloid wheel radially, axial machining accuracy and assembly precision requirement for positioning shaft all need not be very strict, therefore use roller bearing can meet installation precision and transmission accuracy requirement, this just greatly reduces the difficulty of processing of positioning shaft, also reduced the difficulty of processing in scaffold upper bearing (metal) hole, thereby reduced cost of production, improved work efficiency.
The transmission of power of the power intake of power input shaft still adopts spline, but, compare with conventional machines people RV retarder, between this spline and driving eccentric wheel, there is not phase relationship, greatly reduce difficulty of processing, and during assembling, do not affect position relationship and the annexation between two cycloid wheel, thereby greatly reduce assembling difficulty.
Owing to driving eccentric diameter to be greater than the eccentric diameter of transmission, install and drive eccentric mounting hole diameter to be greater than the eccentric positioning hole diameter of installation transmission, thereby drive bearing between eccentric wheel and cycloid wheel can use the roller larger than conventional roller diameter, and then increased the torque resistance of power input shaft, improved the working life of bearing simultaneously, and then improved the working life of RV retarder.
