[0023] Reference figure 1 An example of the base for mounting the reducer of the present invention will be described.
[0024] The base 1 for mounting the reducer is made of a strong metal material. Such as figure 1 As shown, the base 1 for mounting the reducer includes a bottom plate portion 2, a mounting portion 3, and a reinforcing rib portion 4, and the bottom plate portion 2, the mounting portion 3, and the reinforcing rib portion 4 are connected to each other to form a single body.
[0025] First, the structure of the bottom plate 2 will be described.
[0026] The bottom plate 2 has a plate shape and is used to mount the base 1 for mounting the reducer on the mounting object. The bottom plate portion 2 is U-shaped in plan view, and includes a first plate portion 2A extending in the X direction, a second plate portion 2B extending parallel to the first plate portion 2A, and a first plate portion 2B extending in the Y direction perpendicular to the X direction. The third plate portion 2C in which the plate portion 2A and the second plate portion 2B are connected. The bottom plate portion 2 is surrounded by a hollow portion 2E by the first plate portion 2A, the second plate portion 2B, and the third plate portion 2C.
[0027] In the following description of the present invention, the side where the first plate portion 2A and the second plate portion 2B are located in the X direction is referred to as the front side, the side opposite to the front side is referred to as the rear side, and the bottom plate portion in the Y direction The side where 2 is located is called the lower side, and the side opposite to the lower side is called the upper side.
[0028] A plurality of mounting holes 2L penetrating through the bottom plate 2 are respectively provided on the front of the first plate portion 2A, the second plate portion 2B, and the rear portion of the third plate portion 2C. The mounting holes 2L are used to mount the base for the reducer 1 Install on the installation target. The third plate portion 2C has a thin portion 2D partially recessed from the lower side to the upper side of the third plate portion 2C, and the thin portion 2D is provided avoiding the portion where the mounting hole 2L is provided.
[0029] Next, the structure of the mounting part 3 is demonstrated.
[0030] The mounting portion 3 has a plate shape, and stands up from the third plate portion 2C of the bottom plate portion 2 toward the Z direction which is a direction perpendicular to the bottom plate portion 2 over the entire length of the third plate portion 2C in the Y direction. The outer contour of the cross-sectional shape of the mounting portion 3 viewed from the X direction is a substantially inverted U-shaped outer contour with an upper end sealed, and has a size slightly larger than a plate-shaped flange portion J2 of the reducer J described later.
[0031] The central portion of the mounting portion 3 is provided with a penetration portion 3A that penetrates the mounting portion 3 in the X direction. The penetration portion 3A is circular and formed into a size that can be penetrated by the reducer. The reducer has different radial dimensions due to different specifications, and the diameter of the penetration portion 3A of the mounting portion 3 has different diameters corresponding to the reducer of different specifications.
[0032] A reduction gear assembly part 3B is provided around the penetration part 3A of the mounting part 3 with an interval therebetween. The reduction gear fitting portion 3B protrudes toward the front side in the Y direction, so that the thickness in the Y direction is thicker than the thickness of the mounting portion 3 except for the reduction gear fitting portion 3B in the Y direction. The reducer mounting portion 3B is provided with a mounting hole 3L for fixing the later-described plate-shaped flange portion of the reducer J to the base 1 for mounting the gear reducer, and the mounting hole 3L is provided through the gear mounting portion 3B.
[0033] Next, the structure of the reinforcement rib 4 is demonstrated.
[0034] The reinforcing rib 4 has an inverted U-shaped cylindrical shape in a front view, and extends from the edge of the mounting portion 3 toward the side opposite to the side where the third plate portion 2C is located in the X direction. The reinforcing rib 4 extends from the edge of the mounting portion 3 toward the side opposite to the side where the third plate portion 2C is located in the X direction to halfway between the first plate portion 2A and the second plate portion 2B.
[0035] The width of the reinforcing rib 4 in the X direction gradually changes in a smooth manner from the top of the reinforcing rib 4 to the middle of the Y direction of the reinforcing rib 4 from the top of the reinforcing rib 4 toward the bottom plate 2 width. The reinforcing rib 4 includes a circular arc plate 4A located at the upper part and opening downward, and a vertical vertical plate 4B located at the lower part and extending downward from both ends of the circular arc plate 4A to the bottom plate 2. Among them, the width of the circular arc plate 4A in the X direction gradually increases from the top to the lower side, and the vertical plate 4B has a constant width in the X direction.
[0036] The bottom of the reinforcing rib 4 is connected to the bottom plate 2, and a portion of the reinforcing rib 4 near the connection site of the reinforcing rib 4 and the bottom plate 2 is formed to increase the thickness of the reinforcing rib 4 in the Y direction. Into the thick section 4C.
[0037] Next, refer to figure 2 The method of assembling the motor M, the reducer J, and the base 1 for mounting the reducer will be explained.
[0038] The plate-shaped flange portion J2 of the reducer J is formed at approximately the middle position in the axial direction of the housing of the reducer J. With the reducer J passing through the penetration portion 3A, the plate-shaped flange portion J2 of the reducer J Abutting against the mounting portion 3 of the reducer mounting base 1 so that the plate-shaped flange portion J2 of the reducer J overlaps with the mounting portion 3 of the reducer mounting base 1 except for the penetration portion 3A, and Align the mounting hole JL on the plate-shaped flange portion J2 with the mounting hole 3L on the mounting portion 3. Here, the part of the mounting portion 3 other than the penetration portion 3A is slightly larger than the size of the plate-shaped flange portion J2, and it is preferable that the portion of the mounting portion 3 other than the penetration portion 3A has the same size as the plate-shaped flange portion J2. . Fasteners such as bolts are passed through the mounting hole JL and the mounting hole 3L, and then fixed to each other by fasteners such as nuts, so that the reducer J is mounted on the base 1 for mounting the reducer. The reducer J may be mounted on the base 1 for mounting the reducer with the motor M attached, or the motor M may be mounted on the reducer J after being mounted on the base 1 for mounting the reducer.
[0039] When the motor M is provided in the reducer J so as to protrude downward from the housing of the reducer J, the motor M penetrates the hollow portion 2E of the bottom plate 2. When the motor M is provided on the reducer J so as to protrude upward from the housing of the reducer J, the motor M penetrates the notch 4D at the upper end of the reinforcing rib 4.
[0040] Next, refer to Figure 3 ~ Figure 5 The method of manufacturing the base 1 for mounting the reducer of the present invention will be described.
[0041] The method for manufacturing the reducer mounting base 1 of the present invention can be used to manufacture a reducer mounting base 1A capable of mounting a reducer of the first specification and a reducer mounting base 1B capable of mounting a reducer of the second specification, wherein , The radial dimension of the outer peripheral surface of the reducer of the first specification is smaller than the radial dimension of the outer peripheral surface of the reducer of the second specification. Hereinafter, the radial dimension of the outer peripheral surface of the reducer of the first specification is referred to as the first radial dimension, and the radial dimension of the outer peripheral surface of the reducer of the second specification is referred to as the second radial dimension.
[0042] The manufacturing method of the base 1 for mounting a reducer includes at least a blank manufacturing process and a hole expanding process.
[0043] Such as image 3 As shown, a plurality of blanks 5 manufactured through the blank manufacturing process are exactly the same in shape and size. The blank 5 has the same shape and size as the deceleration described above, except for the diameter of the initial through hole 5A and the diameter of the through portion 3A. The base 1 for machine installation is exactly the same. The radial diameter of the initial through hole 5A is smaller than the first radial dimension and the second radial dimension. For ease of description, in the following description, the structure corresponding to the base 1 for mounting the reducer in the blank 5 is marked with figure 1 The same reference numerals are used, and the description is omitted. In the blank manufacturing process, methods such as casting can be used to manufacture the blank.
[0044] Next, refer to Figure 4 as well as Figure 5 , In the reaming process, the initial through hole 5A is separately reamed in diameter using a boring machine. In this way, the initial through holes 5A in the plurality of blanks 5 are respectively expanded into a through portion 3AA having a diameter matching the first radial dimension and a through portion 3AB having a diameter matching the second radial dimension.
[0045] After that, a step of processing the reducer mounting hole 3LA and the reducer mounting hole 3LB on the reducer mounting base 1A and the reducer mounting base 1B, respectively, is performed. Thus, the mounting portion 3 of the reducer mounting base 1A around the penetration portion 3AA and the mounting portion 3 of the reducer mounting base 1B around the penetration 3AB are respectively provided with a reducer mounting hole 3LA And the reducer assembly hole 3LB. The reduction gear assembly hole 3LA and the reduction gear assembly hole 3LB may be provided in plurality at intervals corresponding to the assembly holes provided on the radial flange portion of the reducer as needed.
[0046] In addition, the base 1 for mounting the reducer may be subjected to finishing processing and other processing as required.
[0047] In the above-mentioned blank manufacturing process, casting was used as an example for manufacturing blanks. In the reaming process, a boring machine was used as an example for reaming. However, it goes without saying that this The invention is not limited to the above-mentioned processing means, and other processing means can also be used as long as the required blank can be manufactured and the hole can be enlarged.
[0048] In addition, the diameter of the initial through hole 5A of the blank 5 is set to be smaller than the first radial dimension and the second radial dimension, but the diameter of the initial through hole 5A may be opposite to the first radial dimension and the second radial dimension. The smaller first radial dimension is the same. Thereby, the process of expanding the hole to the first radial dimension can be omitted. Furthermore, in the above description, the reduction gear of the first specification and the reduction gear of the second specification with different radial dimensions have been described as examples, but it goes without saying that three or more specifications with different radial dimensions may also be included. In this case, the diameter of the initial through hole 5A of the blank 5 is set to be less than or equal to the radial dimension of the reducer with the smallest radial dimension among the reducers of multiple specifications.
[0049] In addition, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art can understand that, in addition to at least the above-mentioned blank manufacturing process and reaming process, it can also include other processes such as machining the mounting hole 2L. Regarding this, those skilled in the art can use the means commonly used in the art to perform processing, and the description is omitted here.
