Abstract
The invention relates to the field of harmonic reducers and in particular to a miniaturized harmonic reducer which comprises a wave generator, a rigid gear, a flexible gear, a four-point contact bearing, a shell and a load board, wherein the wave generator is arranged in the flexible gear; the flexible gear is meshed in the rigid gear; the rigid gear is fixed to the shell; the load board is arranged in the shell; and the four-point contact bearing is arranged between the shell and the load board and is fixed by a bearing pressure cover which is also arranged between the shell and the load board. With adoption of the technical scheme, the miniaturized harmonic reducer has the characteristics of large transmission ratio, large bearing capacity and high transmission accuracy.
Description
Technical field
The present invention relates to harmonic speed reducer field, refer in particular to the harmonic speed reducer of a kind of miniaturization.
Background technology
Along with the prosperity of science and technology, the range of application of robot is also increasingly wider, and various types of robots demand has technical grade, also has seeervice level.In service robot field, it it is more the product of demand miniaturization.Though miniaturization, it is also required for certain load capacity, and just because of this, its crucial joint part of service robot is also required to apply to harmonic speed reducer.Service robot wants cube little, and needs for certain bearing capacity to ensure the operation of robot.
Therefore, this is made further research by the present inventor, develops the harmonic speed reducer of a kind of miniaturization, and this case thus produces.
Summary of the invention
It is an object of the invention to provide the harmonic speed reducer of a kind of miniaturization, gear ratio is big, bearing capacity is big, transmission accuracy is high.
To achieve these goals, technical scheme is as follows:
A kind of harmonic speed reducer of miniaturization, including wave producer, just wheel, flexbile gear, four spot contact bearings, housing, load board, described wave producer is arranged in flexbile gear, it is interior that described flexbile gear is engaged on just wheel, described firm wheel is fixed on housing, described load board is arranged in the housing, is provided with four spot contact bearings between described housing and load board, and described four spot contact bearings are fixed by the bearing gland being similarly positioned between housing and load board.
Further, it is provided with flexible bearing between described wave producer and flexbile gear.
Further, being provided with cushion block in described flexbile gear, described load board and cushion block are fixed on flexbile gear both sides by same screw.
Further, described bearing gland is fixed by the female thread of housing.
After using such scheme, the present invention compared with prior art, has the advantage that
Gear ratio is big, bearing capacity is big, transmission accuracy is high, efficiency is high, volume is little, lightweight, stable drive, noise are little.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention；
Label declaration
Wave producer 1, has just taken turns 2, flexbile gear 3, four spot contact bearings 4, housing 5, load board 6,
Bearing gland 7, flexible bearing 8, cushion block 9, screw 10.
Detailed description of the invention
The present invention is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
As shown in the figure, a kind of harmonic speed reducer of miniaturization, including wave producer 1, just take turns 2, flexbile gear 3, four spot contact bearing 4, housing 5, load board 6, wave producer 1 is arranged in flexbile gear 3, wave producer 1 is connected by flexible bearing 8 with flexbile gear 3, and the external tooth of flexbile gear 3 is meshed with the internal tooth of just wheel 2, and flexbile gear 3 rear end connects load board 6, it is connected by the screw 10 with load board 6, thus reaches the effect that output is slowed down.Being provided with cushion block 9 in flexbile gear 3, flexbile gear 3 is fixed between load board 6 and cushion block 9 by screw 10, and cushion block 9 ensures the axiality between flexbile gear 3 and load board 6, thus improves the precision of harmonic speed reducer.
Just wheel 2 is fixed on housing 5, above-mentioned load board 6 is arranged in housing 5, four spot contact bearings 4 it are provided with between housing 5 and load board 6, four spot contact bearings 4 are fixed by the bearing gland 7 being similarly positioned between housing 5 and load board 6, bearing gland 7 is fixed by the female thread of housing 5, and bearing gland 7 limits the axial displacement of four spot contact bearings 4；Four spot contact bearings 4 are a kind of divergence type bearings, can bear the angular contact bearing of axial load and radial load.I.e. ensure that the axiality of product, more can effectively bear axial and moment of torsion radially and the moment of flexure of a fixed load output, conveniently install and unpick and wash.
Above are only the specific embodiment of the present invention, but the design concept of the present invention is not limited thereto, all changes utilizing this design that the present invention carries out unsubstantiality, the behavior invading scope all should be belonged to.
