Abstract
A speed reducer with small return difference, large speed ratio and high accuracy comprises a pin wheel housing, wherein two cycloidal gears with the phase difference of 180 degrees are installed in the pin wheel housing, and a gear pin is installed between the cycloidal gears and the pin wheel housing. The speed reducer with small return difference, large speed ratio and high accuracy is characterized in that a rigid disc and an output disc are coaxially installed at two ends of the cycloidal gears and are connected through a bolt, an input gear shaft is installed in the center of the two discs, two planet gears which are arranged at an angle of 180 degrees and simultaneously meshed with a gear of the input gear shaft is installed at one end of the gear of the input gear shaft, the centers of the two planet gears are respectively provided with a double-offset-crank shaft misplaced at an angle of 180 degrees, the two ends of each double-offset-crank shaft are supported on the two discs through a bearing, and middle double-offset-crank parts of the double-offset-crank shafts are connected with the cycloidal gears through bearings respectively. According to the speed reducer with small return difference, large speed ratio and high accuracy, the input end adopts a one-stage involute gear planetary transmission method, the output end adopts a one-stage cycloidal-pin wheel double-crank transmission method, and the speed reducer with small return difference, large speed ratio and high accuracy has the advantages of being high in bearing capacity, small in return difference and high in transmission accuracy.
Description
Technical field
The utility model relates to retarder, particularly a kind of little return difference large speed ratio high accurate speed reducer.
Background technique
For universal planet-cycloid reducer, want to accomplish that highi degree of accuracy, the retarder that velocity ratio is large, bearing capacity is strong, return difference is little are very difficult.Along with modernization industry is progressively towards automation, intelligent development, robot has progressively replaced manpower work, and has greatly improved manufacturing efficiency, reduced cost of production.But robot must be accurate when operation, this just requires as the supporting retarder precision of robot is high, return difference angle is minimum, and has higher bearing capacity.
Summary of the invention
The utility model provides for solving the technical problem existing in known technology the little return difference large speed ratio high accurate speed reducer that a kind of bearing capacity is strong, return difference is little, transmission accuracy is high.
The technological scheme that the utility model is taked for the technical problem existing in solution known technology is:
A kind of little return difference large speed ratio high accurate speed reducer, comprise pin wheel housing, two cycloid wheel of 180 ° of phase differences are installed in pin wheel housing, between cycloid wheel and pin wheel housing, gear pin is installed, it is characterized in that: the two ends at pin wheel housing hypocycloid wheel are coaxially installed with rigid disk and output disc, rigid disk and output disc are bolted, at the center of rigid disk and output disc, input gear axle is installed, one end at the gear of input gear axle is provided with two planetary pinions that are 180 ° of layouts that simultaneously mesh with gear, two planetary centers are separately installed with two offset crank shofts of 180 ° of dislocation, the two ends of two offset crank shofts by bearings on rigid disk and output disc, the two eccentric mechanism parts in middle part of two offset crank shofts are connected with two cycloid wheel by bearing respectively.
Advantage and the good effect that the utlity model has are:
This retarder is installed two two offset crank shofts in cycloid wheel, make two two offset crank shofts drive cycloid wheel translation simultaneously, while having solved a crankshaft drives cycloid wheel, be subject to force intensity excessive, easily glue together a damaged difficult problem, simultaneously, output disc and rigid disk dress are integrated, and having improved old-fashioned cycloid speed reducer output form is that beam type bearing pin holds flexible stress, and then has improved the bearing capacity of retarder.Cycloidal gear is processed with moving apart from repairing type by equidistant, has increased total number of teeth in engagement, has improved transmission accuracy; Input end is through gear reduction, thereby can obtain larger velocity ratio; Because two two offset crank shofts drive cycloid wheel simultaneously, so design, manufacture and assembly precision must reach higher level and just can make retarder smooth operation, therefore also has the feature of little return difference.

Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and 2, a kind of little return difference large speed ratio high accurate speed reducer, comprises pin wheel housing 1, and two cycloid wheel 2 of 180 ° of phase differences are installed in pin wheel housing, and gear pin 3 is installed between cycloid wheel and pin wheel housing.Two ends at pin wheel housing hypocycloid wheel are coaxially installed with rigid disk 4 and output disc 5, concrete, and rigid disk and output disc are separately by bearings position near two ends in the endoporus of pin wheel housing.Rigid disk is connected by bolt 6 with output disc.At the center of rigid disk and output disc, input gear axle 7 is installed.Concrete, at rigid disk and the center of output disc, be provided with coaxial mounting hole, in two mounting holes, bearing is installed, input gear axle is supported on bearing.One end at the gear of input gear axle is provided with two planetary pinions 8 that are 180 ° of layouts that simultaneously mesh with gear, and two groups of planetary pinions are along the circumferential direction uniformly distributed, and are separated by 180 °.Two planetary centers are separately installed with a dislocation two offset crank shofts 9 of 180 °, concrete, and two offset crank shofts partly consist of misplace two eccentric mechanisms of 180 ° of the coaxial axial end portion in two ends and middle part.The two ends of two offset crank shofts are by bearings on rigid disk and output disc, and the two eccentric mechanism parts in the middle part of two offset crank shofts are connected with two cycloid wheel by bearing respectively.
The two poles of the earth transmission that this retarder has adopted cycloidal-pin wheel and involute gear to form, having done larger improvement aspect product specification structure, manufacturing precision, assembly precision, guarantees that retarder performance and technical order reach required requirement.
