The invention provides a kind of flange with loss of weight through hole.
For solving the foregoing invention purpose; The invention provides a kind of flange; It comprises main part; Said main part comprises the installation through holes that penetrates said main part and is positioned at the peripheral loss of weight through hole of said installation through holes, and the cross section of said installation through holes be a circle, and said loss of weight through hole cross section is the semicircle district that comprises squared region and be arranged at the rectangular both sides.
As further improvement of the present invention, said loss of weight number of openings is provided with 4.
As further improvement of the present invention, said loss of weight through hole comprises first lightening hole and second lightening hole, and the centre of said first lightening hole and said second lightening hole is the center of circle of the cross section of said installation through holes.
As further improvement of the present invention, said loss of weight through hole comprises the 3rd lightening hole and the 4th lightening hole, the center of circle of the cross section of the said installation through holes of interposition of said the 3rd lightening hole and the 4th lightening hole.
As further improvement of the present invention, the line of said first lightening hole and said second lightening hole is perpendicular to the line of said the 3rd lightening hole and the 4th lightening hole.
As further improvement of the present invention, the line of said first lightening hole and said the 4th lightening hole is parallel to the line of said second lightening hole and said the 3rd lightening hole.
As further improvement of the present invention, the length of said loss of weight through hole cross section squared region is 30 millimeters.
As further improvement of the present invention, the radius in said loss of weight through hole cross section semicircle district is 16 millimeters.
As further improvement of the present invention, the radius of said installation through holes cross section is 508 millimeters.
Compared with prior art; Flange provided by the present invention; Through the weight that the loss of weight through hole has reduced flange is set, the quantity that the loss of weight through hole is set simultaneously is four, and is uniformly distributed in the flange main part; The mechanical strength that has guaranteed the flange each several part is consistent, and guarantees the firm and working life that flange is whole.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing relevant of the present invention in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the plan view of flange in one embodiment of the invention.
Wherein, reference character is:
Flange, 100; Main part, 10; Installation through holes, 11; First through hole, 121; Second through hole, 122; Third through-hole, 123; Fourth hole, 124.
Embodiment
Below will combine each embodiment shown in the drawings to describe the present invention.But these embodiments do not limit the present invention, and those of ordinary skill in the art all is included in protection scope of the present invention according to the conversion on structure, method or the function that these embodiments made.
Join shown in Figure 1; The invention provides a kind of flange 100; It comprises main part 10; Said main part 10 comprises the installation through holes 11 that penetrates said main part 10 and is positioned at the peripheral loss of weight through hole of said installation through holes 11, and the cross section of said installation through holes 11 be a circle, and said loss of weight through hole cross section is the semicircle district that comprises squared region and be arranged at the rectangular both sides.
Said loss of weight through hole can effectively reduce the weight of flange 100, and then reduces the weight of the machinery of using this flange 100, reduces the cost of transportation of this machinery.
Wherein, said loss of weight number of openings is provided with 4.
Concrete, the quantity of said installation through holes 11 is set to 1.
Special, said loss of weight through hole comprises first lightening hole 121 and second lightening hole 122, said first lightening hole 121 is the center of circle of the cross section of said installation through holes 11 with the centre of said second lightening hole 122.
Similarly, said loss of weight through hole comprises the 3rd lightening hole 123 and the 4th lightening hole 124, the center of circle of the cross section of the said installation through holes 11 of interposition of said the 3rd lightening hole 123 and the 4th lightening hole 124.
Concrete, the line of said first lightening hole 121 and said second lightening hole 122 is perpendicular to the line of said the 3rd lightening hole 123 and the 4th lightening hole 124.
Further, the line of said first lightening hole 121 and said the 4th lightening hole 124 is parallel to the line of said second lightening hole 122 and said the 3rd lightening hole 123.
