Gear type power transmission of three-head rotating shaver

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 [0001] The invention relates to the technology of a rotary shaver, in particular to a gear transmission technology of a triangular three-headed rotary shaver. Background technique [0002] At present, the gear transmission device of the existing triangular three-head rotary shaver comprises a driving gear, a transmission gear and three cutter head working gears. A cutter head working gear works, and the cutter head working gear drives the cutter head to run through the clutch wheel to realize the shaving function. Such as figure 1 As shown, since the driving gear and transmission gear of this kind of gear transmission are meshed with cylindrical gears, the power of the motor is transmitted between parallel shafts, and the direction of motor transmission cannot be changed. Therefore, the motor must be placed directly below the transmission gear. Make the face of the machine head and the machine body form a certain inclination angle, then the machine body mus...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, since the driving gear and transmission gear of this kind of gear transmission are meshed with cylindrical gears, the power of the motor is transmitted between parallel shafts, and the direction of motor transmission cannot be changed. Therefore, the motor must be placed directly below the transmission gear. Make the face of the machine head and the machine body form a certain inclination angle, then the machine body must be made curved, so that the part held by the hand can only be the lower half of the bent position of the machine body, and the holding part of the hand is relatively far away from the machine head.
