72 are arranged between the two side plates 71.The width of central plate 72 is slightly larger than the width of gear 21
Degree.
Two two wall portions of side of parallel tube wall section 74 and side plate 71 of central plate 72
Section 75 forms the border of the pipeline.
Central plate 72 that is, with the circular section 110 of a quarter, the section is equivalent to cylinder
A quarter.Therefore the section 110 can also be referred to as a quarter cylinder 110.In the section 110
Lower area in be formed with opening 76, the opening be passed through remittance in oil transportation channel mouthful as pipeline and
Work.Two parallel tube wall sections 74 from this opening on central plate 72 straight down
Extend.In the axial direction, two be used for form pipeline tube wall section 74 between interval region quilt
The side wall section 75 of the first side plate 71 is closed.Along axis rightabout, it is used to be formed at two
Interval region between the tube wall section 74 of pipeline is by with the minute surface symmetric design of the first side plate 71 in addition
The side wall section 75 of side plate 71 close.
Side has connecting plate section 73 for being connected with lower component 1 to each side plate 71 thereon.
Side wall section 75 is formed in the downside of corresponding side plate 71.
Side plate 71 and central plate 72 are preferably respectively made up as rushing comer pieces of steel plate.
Side plate 71 is covered each by each radial distance region, is based especially on the rotation of gear 21
Radial distance region for axis, the radial distance region overlay of the side plate is by teeth portion and oil transportation channel
The radial distance region for covering.
Side plate 71 is threadedly coupled and/or is welded to connect with central plate 72 respectively.
