Abstract
The invention provides a gear transmission device used for a three-head rotation typed shaver, and relates to the technical field of rotation typed shaver; the problem to be solved is that the gear transmission device can not change the transmission direction of the motor; the gear transmission device comprises a driving gear, a transmission gear, three cutter head working gears and a gear frame; the transmission gear is provided with two groups of teeth; wherein, one group is engaged to the driving gear which is coaxially arranged on the motor and the other group is engaged to the working gear which is arranged on the gear frame symmetrically about three axis; the axis center of each working gear is provided with a transmission shaft; the upper end of the transmission shaft is provided with a transmission head; the gear transmission device is characterized in that the driving gear and the transmission gear are engaged to each other by a bevel gear type; the gear transmission device is beneficial to reducing the dimension of hand-holding part of the machine body, thus improving the usage comfortableness of the shaver.
Description
Technical field
The present invention relates to the rotary shaver technology, particularly relate to a kind of gear-driven technology of leg-of-mutton three-head rotating shaver.
Background technology
The gear drive of present existing leg-of-mutton three-head rotating shaver, comprise driving gear, travelling gear and three cutter head working gears, driving gear is contained on the motor, driving gear drives travelling gear, travelling gear drives the work of three cutter head working gears simultaneously, the cutter head working gear drives the cutter head running by castle wheel, realizes shaving function.As shown in Figure 1, because the driving gear of this kind gear drive and travelling gear adopt the roller gear engagement, the transmission of the power of motor between parallel axes, can't change the motor transmission direction, so motor must be placed in travelling gear under, if make head veneer portion become certain inclination angle with body, body must be made bending so, so the position of hand gripping can only be the lower semisection of body bending position, the holding area of the hand head of disembarking is far away relatively, has influenced the comfortableness of operation.
Summary of the invention
At the defective that exists in the above-mentioned prior art, technical problem to be solved by this invention provides a kind of head veneer portion and becomes certain inclination angle, body smooth-going with body, so that hand holding part can be easily near head, thereby improve the gear drive of three-head rotating shaver of the comfort of shaver.
In order to solve the problems of the technologies described above, the gear drive of a kind of three-head rotating shaver provided by the present invention, comprise driving gear, travelling gear, three cutter head working gears and tooth rest, travelling gear is installed on the tooth rest, travelling gear is provided with two groups of gear teeth, one group is meshed with the coaxial driving gear that is installed on the motor, another group is meshed with three axisymmetric working gears that are installed on the tooth rest, the axle center of each working gear is provided with a power transmission shaft, the power transmission shaft upper end is provided with driving head, it is characterized in that: driving gear and travelling gear adopt the bevel gear mode to be meshing with each other.
Further, described two groups of gear teeth are internal tooth and two groups of gear teeth of external tooth, and one group of internal tooth is meshed with the coaxial driving gear that is installed on the motor, and one group of external tooth is meshed with three axisymmetric working gears that are installed on the tooth rest.
Further, described two groups of gear teeth are two groups of outer gear teeth, and one group is meshed with the coaxial driving gear that is installed on the motor, and another group is meshed with three axisymmetric working gears that are installed on the tooth rest.
The present invention is because driving gear and travelling gear adopt the bevel gear mode to be meshing with each other, make motor power in the concurrent aces transmission, changed the motor transmission direction, travelling gear is oblique relatively in body puts for motor, head veneer portion becomes certain inclination angle, body smooth-going with body, so that hand holding part can be easily near head, thereby improve the comfort of shaver.

The specific embodiment
Below in conjunction with description of drawings embodiments of the invention are described in further detail, but present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof all should be listed protection scope of the present invention in.
As Fig. 2-shown in Figure 6, the gear drive of a kind of three-head rotating shaver that the embodiment of the invention provided, comprise driving gear 7, travelling gear 4, three cutter head working gears 5 and tooth rest 6, travelling gear 4 is installed on the tooth rest 6, travelling gear 4 is provided with inside and outside two groups of gear teeth, one group of internal tooth is meshed with the coaxial driving gear 7 that is installed on the motor 8, one group of external tooth is meshed with three axisymmetric working gears 5 that are installed on the tooth rest 6, the axle center of each working gear 5 is provided with a power transmission shaft 2, power transmission shaft 2 upper ends are provided with driving head 1, it is characterized in that: driving gear 7 adopts the bevel gear mode to be meshing with each other with travelling gear 4.
When shaving, motor 8 drives driving gear 7 and rotates, driving gear 7 drives the travelling gear 4 with its bevel gear engagement, travelling gear 4 drives 5 work of three cutter head working gears simultaneously, cutter head working gear 5 drives driving head 1 work by power transmission shaft 2, driving head 1 drives the cutter head running, realizes shaving function.
In an embodiment of the present invention, travelling gear also can be provided with two groups of outer gear teeth, and wherein one group is meshed with the coaxial driving gear that is installed on the motor, and another group is meshed with three axisymmetric working gears that are installed on the tooth rest.
