Definitions
- the present invention relates to a motor shaft for a micromotor used as a driving source for various small devices, and a micromotor and a micro geared motor to which the motor shaft is applied.
- a micromotor having an outer diameter of several millimeters has been used as a drive source for a silent ringing vibration generator built in a mobile phone.
- this type of micromotor is used as a driving source for various state-of-the-art devices such as medical devices (for example, a lens driving mechanism at the tip of an endoscope or a driving mechanism of an intrauterine diagnostic treatment apparatus).
- medical devices for example, a lens driving mechanism at the tip of an endoscope or a driving mechanism of an intrauterine diagnostic treatment apparatus.
- the field of use is expected to expand further in the future.

- the reduction ratio is determined by the number of gear teeth on the reduction gear mechanism side and the mode. It is determined by the relationship with the number of teeth of the pinion on the rotor shaft side, and a larger reduction gear ratio can be obtained as the number of gear teeth on the speed reduction gear mechanism side is larger and as the number of teeth on the pinion is smaller.
- the reduction gear head has a size (diameter) restriction, so there is a limit to increasing the number of gear teeth on the reduction gear mechanism.
- the conventional structure as described above is used. With this micro geared motor, there is a limit to reducing the number of teeth by reducing the pinion diameter. For this reason, the conventional micro geared motor has a problem that a sufficiently large reduction ratio cannot be obtained.
- the force with which the pion is joined to the motor shaft by a method such as adhesion or press fitting has the following problems.
- the object of the present invention is to solve the above-described problems of the prior art, to obtain a large reduction ratio by the reduction gear mechanism, and to achieve a high degree of coaxiality between the motor shaft and the pion.

- a motor unit configured by the micromotor of (3) or (4) above, and a reduction gear head unit that is drivingly connected to the motor unit via a pinion formed on the motor shaft. And a micro geared motor.
- the reduction ratio between the pinion formed on the motor shaft of the motor unit and the first reduction gear of the reduction gear head unit is 5 or more.
- the number of teeth of the pinion and the reduction gear is set.
- micro geared motor according to any one of (5) to (7) above, wherein the micro geared motor has an outer diameter of mm or less.
- the micromotor to which the motor shaft is applied, and the microgeared motor the pion can have a sufficiently small diameter, so that a large reduction ratio is obtained by the reduction gear mechanism. be able to.
- the pion is integrally formed on the motor shaft itself, a high degree of coaxiality between the motor shaft and the pion can be secured, so that there is little failure, long life and low noise generation. It does not cause problems such as pion slip and force.
- the manufacturing man-hour and cost can be reduced.
- FIGS. 1 to 3 show an embodiment of a motor shaft of the present invention and a micro geared motor to which the motor shaft is applied.
- FIG. 1 is a longitudinal sectional view, and FIG. 2 is taken along line II-II in FIG. FIG.
- reference numeral 1 denotes a motor unit composed of a micromotor
- 2 denotes a reduction gear head unit that is drivingly connected to the motor unit 1 via a pinion of a motor shaft.
- the power without the reduction gear head portion 2 is the micromotor of the present invention.
- the mechanism of the micromotor that constitutes the motor unit 1 is arbitrary.
- the micromotor is composed of a brushless motor. That is, the motor unit 1 is externally fixed to the housing 3A, the motor shaft bearings 4a and 4b, the motor shaft 5 rotatably held by the bearings 4a and 4b, and the motor shaft portion between the bearings 4a and 4b.
- Rotor magnet 6 and the stator core fixed to the inside of the housing 3A so as to face the rotor magnet 6.
- the structure is similar to a conventional micro geared motor.
- a pinion 8 having an outer diameter equal to or smaller than the outer diameter of the motor shaft 5 is formed (molded) at the distal end of the motor shaft 5.
- the pinion 8 is formed (molded) by subjecting the motor shaft 5 itself to cutting processing such as hobbing or rolling calorie, but other methods, for example, a member on which a pinion is formed are used as a motor.
- the pion 8 can be formed by an appropriate method such as joining to the tip of the shaft.
- the shaft member such as stainless steel, which has a round bar force, is centerlessly moved to measure the outer diameter accuracy and surface.
- the pion 8 is formed (molded) at the tip by cutting or rolling, and then the motor is provided with the pion 8 through processes such as heat treatment and barrel polishing. Finished on shaft 5.
- the pion 8 is a force formed on the front end side of the motor shaft 5.
- FIG. 3 is a perspective view showing the structure of the pion 8 in more detail.
- the pinion 8 is formed by hob-causing the tip of the motor shaft 5, and the range indicated by P in the figure constitutes the pin 8.
- motors that are larger than micro motors in general-sized motors and small motors have corresponding motor torque, so if the pinion diameter is made too small, a large stress is applied to the teeth. As a result, breakage and fatigue failure easily occur.
- the motor torque is very small, from several Nm to several hundreds / z Nm. It was found that the on-tooth part was not damaged or fatigued by repeated loading. Incidentally, the motor torque of the 2 mm diameter micromotor prototyped by the present inventors was 7 ⁇ Nm.
- the reason why the outer diameter of the pinion 8 is set to be equal to or smaller than the outer diameter of the motor shaft 5 is, of course, a force for obtaining a large reduction ratio by reducing the diameter of the pinion.
- the outer diameter of the pinion 8 should be less than the outer diameter of the motor shaft 5 as follows.
- the blank motor shaft before pion formation has a stepped bar shape with a different diameter, especially the machined motor shaft. It becomes difficult to finish the outer diameter accuracy and surface roughness with high accuracy.
- the motor shaft in the blank state before forming the pinion becomes a round bar shape without steps, and the outer diameter accuracy of the motor shaft is achieved by performing centerless processing. And the surface roughness is finished with high accuracy. Then, the centerlessly processed motor shaft is covered with a pion, and the motor shaft 5 having the pion 8 is finished through processes such as heat treatment and barrel polishing.
- the mouth magnet is placed with the motor shaft passing through the bearing (gearhead side) from the front side. It is difficult to fix the motor shaft and the rotor magnet in a highly precise positional relationship when the bearing is interposed, and if the adhesive protrudes, The process of wiping is also difficult.
- the motor shaft 5 and the rotor magnet 6 can be fixed in advance, so that high-accuracy and easy installation is possible. Is possible.
- the pinion 8 having a shaft diameter or less is integrated with the motor shaft 5 of the micromotor. Even in the case where the pion is formed, it is a property peculiar to a micromotor with a very small motor torque that the durability of the pion can be sufficiently strong.
- the diametric force is less than mm and the outer diameter of motor shaft
- a micromotor (micro geared motor) of lmm or less is suitable.
- the lower limit of the pinion outer diameter is not particularly limited as long as the outer diameter of the pinion 8 is smaller than the outer diameter of the motor shaft 5, but generally the strength surface force is at least 80% of the outer diameter of the motor shaft 5. It is preferable to have an outer diameter of the order.
- the reduction gear mechanism 9 includes an output shaft 10 that is disposed on the output side (front end side) of the reduction gear mechanism and that is rotatably supported by the bearing 11.
- the pion 8 includes the reduction gear mechanism portion. It ’s in the 9th gear.
- the structure of the speed reduction gear mechanism section 9 of the speed reduction gear head section 2 is arbitrary, and various structures can be applied.
- the speed reduction gear mechanism section 9 is constituted by a planetary gear speed reduction mechanism.
- the basic structure of this planetary gear speed reduction mechanism is the same as that of the conventional mechanism as shown in FIG. 4, and in this embodiment, two sets of independent arrangements are sequentially arranged from the motor unit 1 side to the output shaft 10 side.
