Description
Technical field
The utility model relates to a kind of gear drive of rotary shaver.
Background technique
The gear drive (Fig. 1) of existing rotary shaver (is example with the three-head rotating shaver) generally includes spur gear z
1, z
2, z
3, z
4Train, driving gear z
1Be contained on the motor shaft gear z
2With gear z
3Be duplicate gear, driving gear z
1Actuation gear z
2, gear z
3Drive three gear z with identical function
4And drive the work of three razor groups simultaneously by the coupling that combines with its elasticity, realize shaving function.Because this kind gear drive is to adopt the cylindrical gears engagement, the axis of motor and razor group parallel axes, interior wrist of most of the time and ancon need rotate upwards 30～60 ° direction during use, thereby when the travelling comfort of using designs the position of handle (being body) and razor group, require then that (being body center's line) forms an angle between razor group and handle center's line, it is substantially parallel with people's skin of face both to have satisfied razor group plane when using like this, and the direction of handle grip makes wrist and ancon comfortable.In order to address this problem, at present one of scheme that adopts (Fig. 1) is exactly a swelled handle portion volume, and motor drive direction turns an angle and places and razor group parallel axes, like this gripping of hand point can leave force bearing point far and volume also bigger, not attractive in appearance, and be held in the hand when using uncomfortable.Another kind of scheme (Fig. 2) is the common cone gear z that adds a pair of change transmission direction in drive gear mechanism
1, z
2Though this scheme has solved the problem of razor group plane and handle part angle, but because the mounting point of cone gear requires than high many of cylindrical gears, the vertex of a cone of two gears must overlap except requirements such as angle, otherwise gear can not normal engaged, and noise is big during use, gear also can sharply wear and tear, mechanism can very fast inefficacy, so production and assembling require very highly, causes the finished product rate low, the cost of production height, and working life is short.Electric shaver is the mechanism (the about 8000rpm of motor output speed) of high speed rotating in addition, part is plastic article, the technical requirements of cone gear, gear carrier accuracy of manufacturing and installation far exceeds the economic accuracy scope of plastic article, the running stability of device, instantaneous speed ratio, the inaccessible economic technology requirement of noise level.So up to the present, still the neither one gear drive can solve the problems referred to above well.
The model utility content
The purpose of this utility model is to provide a kind of and be easy to make and assemble and noise is little, the gear drive of the rotary shaver of long service life for overcoming the deficiencies in the prior art.
For achieving the above object, the utility model discloses a kind of gear drive of rotary shaver, comprise the gear drive between driving gear, at least one half-coupling, driving gear and the half-coupling that is installed on the motor shaft, it is characterized in that: the gear drive between described driving gear, driving gear and the half-coupling, form by at least one cylinder bevel gear and several cylinders gear.
Compare with the gear drive of existing rotary shaver, the gear drive of the rotary shaver in the utility model is owing to the gear drive between driving gear and driving gear and coupling is made up of a cylinder bevel gear and several cylinders gear, therefore can reach the axis of adjusting motor and the angle between the razor group axis by the tapering that changes the cylinder bevel gear to satisfy the angle of (being body center's line) between razor group and handle center's line, it is substantially parallel with people's skin of face both to have satisfied razor group plane when making use, can guarantee to operate comfortable again.Also have the following advantages simultaneously: move the normal engaged that (as long as the inner space allows) can not influence this gear pair when 1, installing along the position on its axial direction owing to the cylindrical gears that is meshed with the cylinder bevel gear; 2, intermeshing cylinder bevel gear and cylindrical gears require suitable with cylindrical gears along having separability perpendicular to the centre distance on the direction of center line; Compare the requirement of having lacked vertex of a cone coincidence with a pair of cone gear installation when 3, assembling; 4, this cylinder bevel gear can mesh with the cylindrical gears of the different numbers of teeth when improving product specification, can inherit and use and needn't make again, reduces the cost of product development.Just owing to the existence of above-mentioned advantage, this driving mechanism has greatly been simplified the technological requirement of making and assembling, and has reduced cost, improved quality of product, and noise is little, long service life, has solved problems of the prior art well.
Below in conjunction with the drawings and specific embodiments the utility model is further described:
