Abstract
The utility model relates to a wandering star formula burnishing machine flexible drive mechanism, this mechanism include the lower wall axle as the input shaft, lower wall axle and lower wall shaft flange looks rigid coupling, the installation that cooperatees of a lower wall shaft flange outer lane and a hydraulic pressure bearing assembly's upper cover inner circle, the equipartition has a plurality of semi -circles to dial the groove on the lower wall shaft flange outer lane, and the groove is dialled to the semi -circle that circles the same figure of equipartition in hydraulic pressure bearing assembly's the upper cover, the semi -circle that circles in semi -circle group groove on the lower wall shaft flange outer lane and hydraulic pressure bearing assembly's the upper cover is dialled the groove one -to -one and is formed multiunit cylinder hole, and every cylindrical inner hole of group packs into and overlaps group round pin subassembly of forming by a set of rod iron and nylon. The utility model provides a hydraulic pressure axle subassembly and an input shaft difficult problem to adopt rod iron and the flexonics that the nylon cover made up, promoted stability, the machining precision of equipment, reduced fault rate, the maintenance degree of difficulty of equipment simultaneously.
Description
Technical field
The utility model belongs to planetary grinding/polishing machine field, is specifically related to a kind of planetary grinding/polishing machine flexible drive mechanism.
Background technique
In traditional planetary grinding/polishing machine equipment, usually adopt crossed roller bearing to drive lower wall, equipment precision is poor, bearing capacity is low, and along with development in science and technology, market demand equipment precision is more and more higher, bearing capacity is increasing, and traditional crossed roller bearing can not be met the need of market.Comply with the market demand, high-precision hydraulic bearing unit is adopted to replace traditional crossed roller bearing in planetary grinding/polishing machine equipment, improve equipment precision and bearing capacity, and by structural limitations, traditional Placement can not meet topology requirement, and the connection between fluid bearing assembly and input shaft just becomes technological difficulties.
Model utility content
The purpose of this utility model is to overcome prior art Problems existing, and provide a kind of wandering star type buffing machine flexible drive mechanism, the stability of lifting means, machining accuracy, reduce the rate of fault of equipment, maintenance difficulty simultaneously.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of wandering star type buffing machine flexible drive mechanism, this mechanism comprises the lower wall axle as input shaft, described lower wall axle and lower wall shaft flange Joint, match with the upper cover inner ring of a fluid bearing assembly and install in described lower wall shaft flange outer ring, described lower wall shaft flange outer ring is evenly equipped with multiple semicircle allocating slot, and uniform same number of semicircle allocating slot on the upper cover inner ring of described fluid bearing assembly, semicircle allocating slot one_to_one corresponding on semicircle allocating slot on described lower wall shaft flange outer ring and the upper cover inner ring of fluid bearing assembly forms organizes cylindrical hole more, often organize the finger assembly loading in cylindrical hole and be made up of one group of rod iron and nylon jacket, described lower wall shaft flange is by finger Component driver fluid bearing assembly, form flexible drive mechanism.
Further, described lower wall shaft flange exterior edge face is connected with gland.
Further, the geomery of described gland covers rod iron end face at least partly and is axially formed spacing to it.
Further, between described rod iron and nylon jacket be interference fit.
Further, described lower wall shaft flange and fluid bearing assembly are respectively equipped with eight semicircle allocating slots, and form eight groups of cylindrical holes.
The beneficial effects of the utility model are:
1, in the utility model, lower wall shaft flange and lower wall axle are connected, uniform 8 semicircle allocating slots on lower wall shaft flange outer ring, correspondingly with 8 semicircle allocating slots uniform on the upper cover inner ring in fluid bearing assembly form 8 groups of cylindrical holes, 8 groups of rod irons and nylon jacket assembly is loaded in cylindrical hole, so not only solve the difficult problem that tradition can not be used to be connected by structural limitations fluid bearing assembly and lower wall shaft flange, and compared with traditional connection, adopt herein and flexibly connect, both comparatively high pulling torque be can transmit, and precision and the stationarity of transmission significantly can be promoted again.
2, the combination flexible drive mechanism of the utility model employing, can make the axis of fluid bearing and the perfection of radial location function play, ensure the machining accuracy of equipment, effectively reduce again the difficulty of processing of part, decrease the processing cost of equipment; Dismounting is simple simultaneously, is convenient to maintenance, decreases the maintenance cost of equipment.
