Description of the invention (1) [Field of the invention] The present invention relates to a device for integrating a motor and a gear, particularly a structure and design of a motor integrated into a gear mechanism, so that the motor can surround the motor. The rotating shaft rotation t and the conventional device can also achieve the function of downsizing and transmission and miniaturization. [Prior technology] In order to provide different power output, the conventional motor must be combined with an external gear box, and the motor and the gear box are manufactured separately. Therefore, the combination of the conventional motor and the gear box is a combination of the gear box casing and the motor casing. After fixing, the motor output shaft is sleeved into the pinion gear. After installing other gear structures, the pinion gear on the output shaft is started by the motor, which drives the overall transmission mechanism to output and obtain different speeds and torques. Generally, the applications that require variable-speed output are achieved in the above manner. However, with the increasing progress of control applications, the internal drive parts are becoming more and more precise. The traditional heavy-duty motor and gearbox variable-speed output equipment cannot meet the current requirements of short and thin control parts. . [Objective of the Invention] The main object of the present invention is to provide a device that integrates a motor and a gear, so that the motor assembly and the gear can be manufactured and assembled together, and can be made smaller. In order to achieve the above object, a novel transmission structure is adopted in the present invention, which mainly includes a swing arm, a plurality of motors, and a main rotating shaft. The motor stator assembly is fixed on the rotating arm, and the swing arm and the main rotating shaft pivot Then, the tooth shape of the external gear on the motor rotor and the external gear on the main rotating shaft are chewed together, that is, when the motor is started, the entire motor will be rotated around the main rotating shaft at the same time, and the shape (: Jw _ 3 · AM —.1 Loading — —'II Booking Travel (Please read the notes on the back before filling this page) This paper is applicable in the national standard (CMS) A4 specification (210X 297 mm) 83.3.10,000 5. Description of the invention (2) The driving arm rotates around the main axis of rotation. In addition, since the motor itself rotates around the main axis of rotation, to input power to the motor from the outside, a set of brushes must be set on the main axis of rotation or the motor By adding an internal power supply to the swing arm, this group of brush devices can be omitted.

Description of the invention (3) This invention is made by It is composed of a swing arm 1, a motor 2 and a main rotating shaft 3. The rotary arm 1 is fixedly combined with the motor 2 and pivotally combined with the main rotating shaft 3. The rotor 21 of the motor 2 is provided with an external gear 211, and the external gear 211 and the external gear 31 provided on the main rotating shaft 3 are chewed with each other, so that both the arm 1 and the motor 2 can rotate around the main rotating shaft 3. Please refer to FIG. 2 again. This is a schematic diagram of the rotation of the arm 1 and the motor 2 relative to the main rotation axis 3 according to the present invention. Since the motor 2 is fixed to the swing arm! The arm 1 is pivotally connected to the main rotating shaft, so the point A on the stator of the motor 2 is relatively fixed with the point B on the rotor 1, and the point C on the rotor 21 is relatively rotated with the point A. When the motor 2 drives the rotor 21 to rotate in a clockwise direction relative to the axis of the motor, the external gears 211 and 31 are chewed together to drive the motor 2 and the swing arm 1 to rotate around the main rotation shaft 3 as a whole. As shown in 2 (a) ~. Therefore, if a transmission element (not shown in the figure) is fixed to the swing arm I, the swing element 1 can drive the transmission element to rotate. Since the number of teeth of the outer gear 211 of the rotor and the outer gear 31 of the main rotating shaft 3 are the same in the first figure, the ratio of the speed of the motor 2 to the speed of the swing arm 1 in the second figure is 1: 1. The gear ratio can be changed to get different speed and torque output. Please refer to FIG. 3 again. This is a first embodiment of the present invention, which includes a swing arm 1, two motors 2, and a main rotating shaft 3. Compared with the first figure, the main difference is that the main rotating shaft 3 is located at the center of the rotary arm 1 and the two motors 2 are symmetrically located on both sides of the main rotating shaft 3. Due to the symmetrical structure, the dynamic balance of the overall mechanism can be obtained. Based on this balance principle, three or more sets of motors 2 can also be symmetrically arranged on the main rotating shaft 3 as the center.

Description of the invention (4) In order to avoid the excessive inertia of the motor 2 and increase the burden on the motor, the present invention The middle motor 2 is preferably a brushless motor with an outer rotor type that can be made into a very small volume. The outer rotor brushless motor is a conventional structure that mainly includes a rotor 21, an upper pole piece 22, and a lower pole piece. 23. A shaft tube 24, a coil winding 25 and a circuit board 26. The rotor 21 includes an external gear 211, a magnet 212, and a pivot shaft 213. The upper and lower pole pieces 22, 23 and the shaft tube 24 are made of a magnetically permeable material After winding a coil (not shown) around the coil winding sleeve 25 and passing in current, a magnetic flux can be generated on the shaft tube 24 and magnetically permeable through the upper and lower pole pieces 22 and 23 to generate the current generated by the current. The axial magnetic flux is turned into a radial magnetic flux. The driving current is detected and controlled by the inductive element on the circuit board 26 to drive the magnet 212 on the rotor 21 to rotate about the pivot shaft 213. The motor coil winding 25 in Figure 3 is fixed on the swing arm 1 and rotates around the main rotating shaft 3. If external DC power is required, a set of brushes must be provided on the main rotating shaft 3 to provide a relative The external DC power line rotating on the main rotating shaft 3 uses a brush to transmit the DC power to the circuit board% and the coil winding 25 so that the power lines connected to the motor circuit board 26 and the coil winding 25 are fixed relative to the motor 2. If the structure of this brush is to be removed, an internal DC power supply can be provided on the swing arm, so that the positive and negative poles of the power input of the motor remain unchanged. Please refer to FIG. 4, the main rotating shaft 3 in the present invention is provided with two bearings 311, 312 is pivotally connected to the swing arm 1, and the contact points of the brushes are separately arranged on the two bearings 311 and 312, and the two bearings 311 and 312 are polarized by an insulating sheet 313. Since the main rotating shaft 3 is a stationary The fixing part 'so that the external power can be introduced from the power cord 32 on the main rotating shaft 3, and the two poles of the power are separated (please read the note on the back before filling this page)-installation.

Description of the invention (5) By drawing out the brush contacts on the two bearings 311 and 312, a power source relatively fixed to the motor 2 can be obtained Line 2 7. The form of the brush can also be other known structures, such as using coaxial rings with different diameters, etc. By combining the disassembled components in FIG. 3, a perspective view of the first embodiment of the present invention in FIG. 5 can be obtained. Please refer to FIG. 6 again, this is a second embodiment of the present invention. Compared to the first embodiment of FIG. 3, an internal gear 4 is provided in FIG. The internal gear 4 is coaxially pivoted with the main rotating shaft 3, and the internal gear 4 meshes with the rotor external gear 211 of the motor 2. If the transmission element (not shown in the figure) fixedly connected to the rotary arm 1 is changed to the internal gear, Gear 4 is fixedly connected, and the larger number of teeth of the internal gear 4 can be used to increase the ratio of the motor speed to the speed of the transmission element to obtain a larger torque output. For example, if the external gear 211 of the motor with 44 teeth matches the 40 teeth The external gear 31 of the main rotating shaft, then, the transmission element fixed to the rotary arm 1 can obtain an acceleration output, and the ratio of the rotation speed of the motor to the rotation speed of the transmission element is 40: 44 = 1: 1.1. If you want to obtain a larger speed ratio than 値 by simply changing the number of teeth, it will be limited by the minimum volume of the motor 2 and cannot effectively reduce the number of teeth of the external gear 2U. Therefore, the number of teeth of the external gear 31 on the main rotating shaft 3 must be increased. If the number of teeth is increased too much, the diameter of the external gear 31 will increase and the volume of the entire device will increase. If the transmission element is fixed to the internal gear 4 with 120 teeth, the output of the deceleration can be obtained under the condition that the length of the entire device is very small (the diameter of the internal gear 4 is close to the length of the arm 1). The ratio of the speed of the motor to the speed of the external components is 190: ^:: 1.1. Therefore, by using the design of the internal gear 4, the power output of a specific speed ratio can be obtained by adjusting the number of teeth of each gear by 40 44.
