Description

  The present invention relates to an output mechanism of a reduction gear, and in particular, the rotation shaft of the reduction gear in the prior art is changed by fixing the rotation shaft by a first fixing member disposed in an annular guide rail of a sleeve. The present invention relates to an output mechanism of a speed reducer that can solve the problem that a member is worn or the operation is not smoothly performed, can extend the product life, and can improve convenience in use.

  An output mechanism of a conventional speed reducer will be described with reference to FIG. As shown in FIG. 1, generally, the output mechanism of the speed reduction mechanism mainly includes a speed reducer main body 1, a rotating shaft 2, and a fixed member 25. A sleeve 11 is disposed in the speed reducer main body 1. A groove 12 is provided on the surface of the inner edge of the sleeve 11. A positioning groove 21 is provided on the surface of the outer edge of the rotary shaft 2. The fixing member 25 is an insertion pin. In use, the user inserts the rotating shaft 2 into the sleeve 11 of the speed reducer main body 1, matches the position of the positioning groove 21 of the rotating shaft 2 with the position of the groove 12 of the sleeve 11, and moves the fixing member 25. The rotating shaft 2 is inserted into the positioning groove 21 and the groove 12 of the sleeve 11.

  Thereby, the rotating shaft 2 can be fixed to the sleeve 11. After the motor 26 is connected to the speed reducer main body 1, the motor 26 can rotate the rotating shaft 2 of the speed reducer. The speed reducer can reduce the rotational speed based on the gear ratio. Please refer to FIG. As shown in FIG. 2, the transmission member 27 of another power device such as a gear is connected to the rotation shaft 2 of the speed reducer, whereby the power of the speed reducer is transmitted to the other power device. The internal structure and operating principle of the speed reducer are conventional techniques and will not be described in detail here.

As will be described with reference to FIG. 2, the output mechanism of the conventional speed reducer can achieve the purpose of transmitting power, but when the rotary shaft 2 is inserted into the sleeve 11 of the speed reducer main body 1, the rotary shaft 2 Since there is no mechanism for fixing the insertion position or depth, the rotary shaft 2 is likely to change during use due to factors such as gravity and external force during mounting. Thereby, a member may be worn out and operation | movement may not be performed smoothly. For this reason, it is inconvenient in use and the product life is shortened, and improvement has been demanded.
The inventor of the present invention conducted research and development in order to solve the above-described drawbacks of the conventional speed reducer.

DESCRIPTION OF EMBODIMENTS Embodiments showing the objects, features, and effects of the present invention will be described in detail with reference to the drawings.
First, a description will be given with reference to FIG. As shown in FIG. 3, the output mechanism of the speed reducer according to an embodiment of the present invention includes a speed reducer body 3 and a rotating shaft mechanism 4.

A sleeve 31 is disposed in the speed reducer main body 3. A storage chamber 32 is provided in the sleeve 31. This will be described with reference to FIG. A linear guide rail 33 and at least one annular guide rail 34 are provided on the surface of the inner edge of the sleeve 31. The annular guide rail 34 and the linear guide rail 33 communicate with each other.
Description will be made with reference to FIG. A motor 5 is connected to the bottom surface of the speed reducer main body 3. Here, the other structure of the speed reducer main body 3, the connection method with the motor 5 and the operating principle belong to the prior art and are not the technical features of the present invention, and therefore will not be described in detail here.

As shown in FIG. 3, the rotary shaft mechanism 4 is provided through the accommodation chamber 32 of the sleeve 31 of the speed reducer main body 3. The rotating shaft mechanism 4 includes a rotating shaft 41, at least one first fixing member 42 and a second fixing member 43. A positioning groove 412 is provided at the end 411 of the rotating shaft 41.
This will be described with reference to FIG. The width and position of the positioning groove 412 correspond to the width and position of the linear guide rail 33 of the sleeve 31. The rotating shaft 41 has at least one concave hole 413. The position of the concave hole 413 corresponds to the position of the annular guide rail 34 of the sleeve 31. The first fixing member 42 is fitted and fixed in the concave hole 413 of the rotating shaft 41. The first fixing member 42 is a convex block.

  As shown in FIG. 4, since the width of the first fixing member 42 corresponds to the width of the annular guide rail 34, the first fixing member 42 is disposed in the annular guide rail 34 of the sleeve 31. . As a result, the rotation shaft 41 rotates and changes along the annular guide rail 34 in the sleeve 31. As shown in FIG. 4, the second fixing member 43 is inserted into the linear guide rail 33 of the sleeve 31 and the positioning groove 412 of the rotating shaft 41. Thereby, the rotating shaft 41 is fixed in the sleeve 31. The second fixing member 43 is an insertion pin.

  This will be described with reference to FIGS. As shown in FIGS. 3 and 5, when the user mounts the rotary shaft mechanism 4 in the sleeve 31 of the speed reducer main body 3, first, the first fixing member 42 is fixed onto the concave hole 413 of the rotary shaft 41. The position of the first fixing member 42 and the position of the linear guide rail 33 of the sleeve 31 are made to correspond to each other. Next, the first fixing member 42 enters the sleeve 31 along the linear guide rail 33. When the rotary shaft 41 continues to be inserted into the sleeve 31 and the position of the first fixing member 42 reaches the position of the annular guide rail 34, the position of the concave hole 413 to which the first fixing member 42 is fixed, and the sleeve Therefore, the user can rotate the rotating shaft 41 in the clockwise or counterclockwise direction so that the first fixing member 42 enters the annular guide rail 34. it can.

  That is, the first fixing member 42 can be rotated and shifted along the annular guide rail 34. Next, by rotating the rotating shaft 41 by a predetermined angle, the position of the positioning groove 412 of the rotating shaft 41 is made to correspond to the position of the linear guide rail 33 of the sleeve 31 (see FIG. 6). As shown in FIG. 6, in the present embodiment, the rotation angle of the rotation shaft 41 is about 180 degrees. This will be described with reference to FIG. As shown in FIG. 7, at this time, the user can insert the second fixing member 43 into the linear slide rail 33 of the sleeve 31 and the positioning groove 412 of the rotating shaft 41. Thereby, the rotating shaft 41 can be fixed in the sleeve 31. At this time, the position of the first fixing member 42 in the annular guide rail 34 is also restricted, and the first fixing member 42 does not rotate and change arbitrarily. The rotating shaft mechanism 4 is attached to the speed reducer main body 3 in the manner described above.

  This will be described with reference to FIG. As shown in FIG. 8, the rotation shaft 41 is mounted in the sleeve 31, so that the motor 5 can rotate the sleeve 31 and the rotation shaft 41. Moreover, the rotational speed of the rotating shaft 41 can be decelerated by the gear ratio. The rotary shaft 41 is connected to a transmission member 6 of another power device such as a gear. Thereby, the power of a reduction gear can be transmitted to another power unit.

  This will be described with reference to FIGS. As shown in FIGS. 4 and 8, at least one annular guide rail 34 is provided on the surface of the inner edge of the sleeve 31. The first fixing member 42 of the rotating shaft mechanism 4 is fixed in the concave hole 413 of the rotating shaft 41 and is disposed in the annular guide rail 34 of the sleeve 31. Thereby, when the rotating shaft 41 is mounted in the sleeve 31, the rotating shaft 41 can be fixed. As a result, it is possible to solve the problems in the prior art where the rotating shaft 2 is displaced and the members are worn out or the operation is not smoothly performed, and the product life can be extended and the convenience in use is enhanced. Can do.
