Abstract
The utility model relates to a harmonic gear roller-type wave generator and is characterized in that the wave generator is composed of hollow rollers, roller cores, supporting frames and a fixing seat. Two supporting frames are elliptic and uniformly distributed with small holes closely matched with the roller cores. The outer sides of the roller cores are provided with the free-revolving hollow rollers. The outer contour line of the group of the hollow rollers is elliptic. The utility model has the advantages of simple structure and a lower cost, especially is suitable for a harmonic gear speed reducer with a plastic flexible gear.
Description
Affiliated technical field
The utility model relates to a kind of wave-generator of harmonic gear speed reducer, can promote flexbile gear during this wave-generator rotation and rotate.
Background technique
Harmonic gear reducer has just been taken turns flexbile gear by wave-generator and has been formed, and wave-generator is made up of oval wheel disc and flexible bearing again traditionally.Just wheel forms a pair of inside engaged gear transmission with flexbile gear.When wave-generator runs up with high speed rotor, flexible bearing also turns round in flexbile gear thereupon, forces the running of flexbile gear ovalize, utilizes firm wheel poor with the number of teeth of this a pair of engaging gear of flexbile gear, can obtain needed bigger reduction speed ratio, realize the low-speed running of flexbile gear.
The wave-generator of this structure adopts flexible bearing, and the Internal and external cycle of flexible bearing needs repeated deformation when wave-generator rotates, and is tired easily, the life-span of having limited harmonic gear.And the material price costliness of flexible bearing use, the manufacturing process complexity, cost is higher.
Summary of the invention
In order to overcome the deficiency of existing harmonic gear speed reducer, the utility model proposes a kind of simple in structure, the solution of the roller shape wave-generator of lower-cost harmonic gear.
This roller shape wave-generator scheme is applied to adopt the harmonic gear of plastics flexbile gear, can reduce the cost of harmonic gear significantly, also makes the manufacturing process of harmonic gear simpler.
The roller shape wave-generator of harmonic gear of the present utility model, its technological scheme is: wave-generator rolls core support fixed base by hollow roller and forms.Two support ovalisation, the even distribution in edge can with roll the friction tight aperture of core.Roll the core outside and be with the hollow roller that can freely rotate.Hollow roller group's outer contour ovalize.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an elevation cross-sectional view of the present utility model.
Fig. 2 is a top plan view of the present utility model
Among Fig. 1
1. hollow roller 2. rolls core, 3. support, 4. fixed base.
Among Fig. 2
1. hollow roller 2. rolls core, 3. support, 4. fixed base.
Embodiment
The quantity of roller is decided by the flexbile gear number of teeth of harmonic gear.The many more precision of roller quantity are high more, but the output torque of restriction harmonic gear.
