Embodiment Construction

[0028] Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings.

[0029] This series of reduction gears includes a vertically mounted reduction gear VG with the input shaft placed on the upper side in the vertical direction and an output shaft placed on the lower side in the vertical direction, and a horizontally mounted reduction gear unit with the output shaft placed horizontally. The horizontal reduction gear HG is used as a constituent element. In addition, the concept of "horizontal arrangement" here includes not only strictly horizontal, but also the concept of being slightly (for example, ±20 degrees) inclined from horizontal.

[0030] exist Figure 1 to Figure 5 shows an example of the structure of the vertical first speed reducer VG1, in Figure 6 ~ Figure 8 A configuration example in which the first reduction gear HG1 is placed horizontally is shown in .

[0031] Starting from the outline, both t...

Abstract

The reduction gear series of the present invention includes a vertical reduction gear and a horizontal reduction gear, wherein at least the shell on the opposite load side is common to the vertical gear reducer and the horizontal gear reducer, and one end of the first lubricating channel of the opposite load side shell is connected to the load. The outer circumference of the housing on the opposite side is opened, and the other end is opened to the same space as the speed reduction mechanism at the first part. One end of the second lubrication passage is opened on the outer circumference of the housing on the opposite load side, and the other end is radially outward from the first part. The second part opens to the same space as the speed reduction mechanism. The vertical speed reduction device has a first through hole in the load side housing and a first pump mechanism. The first pump mechanism has one end connected to the first through hole and the other end connected to the first through hole. The first lubricating pipe connected to the 1 lubricating passage is arranged so that the first lubricating passage is located on the upper side in the vertical direction and the second lubricating passage is located on the lower side in the vertical direction of the horizontal reduction gear unit. Oil gauge for the 2nd lubrication channel.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2015-243650 filed in Japan on December 14, 2015. The entire contents of this Japanese application are incorporated herein by reference. technical field [0002] The invention relates to a series of reduction gears. Background technique [0003] Patent Document 1 discloses that a pump mechanism is attached to a reduction gear transmission that is used vertically by placing the input shaft on the upper side in the vertical direction and the output shaft on the lower side in the vertical direction to achieve good lubrication. . [0004] However, in addition to the case where the reduction gear is used vertically, there are cases where the output shaft is arranged horizontally and used horizontally. [0005] However, the lubricating structure of the reduction gear is different when it is used vertically and when it is used horizontally. [0006] Therefore, in the past, the through holes required ...
