Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to massage machines, especially electric massagers with high engagement accuracy. This relates to a gear device for a surge machine.

0002

[Conventional technology]

Conventionally, electric massage machines powered by motors are compared with massage rollers, etc. In order to rotate the target at low speed, the motor and massage roller etc. are connected to a worm gear etc. to transmit power. connected as a means of delivery.

0003

[Problem that the idea aims to solve]

Conventional electric massage machines have a worm home on the main shaft, which is equipped with massage rollers, etc. The power is transmitted by fitting an output gear such as an eel, and the main shaft is driven by a bearing in the gear case. It is pivoted. Metal pipe material is used for the main shaft, but the finishing accuracy of the pipe material Therefore, runout may occur during rotation, and the output gear may rotate eccentrically. Kaka If the This may cause a malfunction.

0004 Therefore, we prevent gear meshing failure due to eccentricity of the output gear, reduce noise, and extend the life of the gear. Technical issues will arise that need to be solved in order to bring life to life, and this invention is designed to address these issues. The purpose is to solve the problem.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, this invention was developed in a gear-driven electric massage machine. , a boss is formed on the output gear fitted to the main shaft, and the boss is fitted into the bearing of the gear case. The present invention proposes a massage machine characterized in that the main shaft is pivotally supported.

[0006]

[Effect] The output gear fitted to the main shaft has a boss formed therein, and the boss is attached to the bearing of the gear case. The bearing directly supports the output gear. Therefore, the rotation center of the output gear is clear. The input gear and output are The distance between the shafts and the power gear is kept constant.

[0007]

【Example】

An embodiment of this invention will be described below with reference to the drawings. For convenience of explanation, the map The overall configuration of the surge machine will be explained. Figure 1 shows a cloth that covers the mechanism part 2 of the massage machine 1. FIG. 3 is a plan view with the manufactured cover removed. The motor 4 and circuit board are in the lower case 3. 5. The operation switch board 6 etc. are attached, and the main shaft 7 of the mechanism section 2 is connected to the lower case 3 and the upper case. It is mounted between bearing fixing parts 9, 9 provided near the left and right edges of the base 8.

[0008] The main shaft 7 passes through the input gear case 10 in the center, and has a wall in the center as shown in FIG. Power is supplied via a worm gear 12 fitted with a worm wheel 11 and connected to a motor 4. is transmitted. A cylindrical body that is a massage member loosely fitted on the main shaft 7 so as to be freely movable in the axial direction 13, 13 are large-diameter end plates 15 at both ends of the central cylindrical portions 14, 14 shown by chain lines in FIG. , 16, 15, and 16 are fixedly installed. Near the periphery of the end plates 15, 16, 15, 16 The rollers 17, 17..., 18, 18..., which are pivotally supported nearby, are arranged at appropriate intervals, and in this implementation In the example, wide rollers 17, 17... and short rollers 18, 18... are arranged at 60 degree intervals. are arranged alternately. In addition, 19, 19... are ribs provided in the central cylinder portions 14, 14. It is.

[0009] The end faces of the inner end plates 16, 16 on the input gear case 10 side are inclined with respect to the main shaft 7. The inclined plates 20, 20 which are parallel to this end surface are protruded, and the inclined plates 20, 20 The kneading members 22, 22 are freely rotatably attached via ball bearings 21, 21 to the It is being The massaging members 22, 22 are rubber pressing pieces 2 provided with protrusions at appropriate intervals. 3 and 23 are attached to resin rings 24 and 24. Two massage members 22, 22 are inclined in opposite directions, so when the main shaft 7 is rotated by the motor 4, , the kneading members 22, 22 continuously open and close, and knead the human body such as the calf. Can be done.

0010 The worm wheel 11 shown in Fig. 2 is molded from nylon resin, and has both left and right sides. The bosses 25, 25 are provided in a protruding manner, and the outer peripheral surfaces of the bosses 25, 25 are formed into perfect circles. cormorant The foam wheel 11 is inserted into the center of the main shaft 7 and fixed with a screw 26. Ru. Fixing the bearings of the gear cases 10a and 10b, which are divided into left and right halves. Resin bearings 28, 28 are inserted into the parts 27, 27 from the inner surface. said axis The keys 29, 29 provided on the outer periphery of the bearings 28, 28 are inserted into the inner periphery of the bearing fixing parts 27, 27. It fits into the key grooves 30, 30, and the bearings 28, 28 rotate relative to the bearing fixing parts 27, 27. It is kept in a state of immobility. Then, the gear cases 10a and 10b are attached to the left and right sides of the main shaft 7. Insert the bearings 28, 28 into the bosses 25, 25 of the worm wheel 11, respectively. and tighten the gear cases 10a and 10b with screws (not shown) to assemble the gear device. Can be erected.

[0011] This invention may be modified in various ways as long as it does not depart from the spirit of this invention. Naturally, this invention extends to modified versions of these.

0012

[Effect of the idea]

As explained in detail in the above embodiment, this idea uses a gear case bearing to output power. Since the gear boss is directly supported, the rotation center of the output gear is clear and the main shaft is perfectly round. It is not affected by accuracy or bending, and the output gear does not become eccentric. Therefore, the input Since the distance between the gear and the output gear is maintained constant, there is no problem in meshing. Eliminates the causes of noise and abnormal wear, providing a quiet and long-life massage machine. This is a practical and valuable idea.
