Abstract
The utility model belongs to the technical field of automobile part tools, and particularly relates to a center flange. The center flange comprises a large circular truncated cone body, a middle circular truncated cone body and a small circular truncated cone body which are connected integrally and coaxially, wherein an inward concave part is formed in the upper end surface of the large circular truncated cone body, the middle circular truncated cone body is arranged in the inward concave part, an upper conical hole is formed in the center of the small circular truncated cone body, the upper conical hole, a middle conical hole and a lower conical hole are communicated with one another, hole diameters of the upper, middle and lower conical holes are increased gradually, and conical degrees of the upper, middle and lower conical holes are consistent; a side hole in a side bulge is communicated with the middle conical hole. The center flange is reasonable in structure, so that the flange cannot fall off easily, and the service life of the flange can be prolonged.
Description
Technical field
The utility model belongs to auto parts apparatus technical field, relates in particular to a kind of center flange.
Background technique
Flange is constituent element important in auto parts and components, and its Main Function is the link of car transmissions.The structure of current flange is, comprises a cylindrical body, then on cylindrical body, offers through hole, is provided with chimb at cylindrical side, offers fixed hole on chimb.The structure of this type of flange makes the activity space of bearing in through hole less, rotates dumb.And the fixed hole setting of chimb also comes off than being easier to.Because the unreasonable flange ratio that makes of its structural design is easier to come off, and use dumb.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, provides a kind of rational in infrastructure, makes flange be not easy to come off, the center flange that can extend its service time, and its technological scheme is as follows:
A kind of center flange, it is characterized in that, described center flange includes coaxial large Rotary-table, middle Rotary-table and the little Rotary-table connecting of one, the upper-end surface of large Rotary-table is provided with sunken inside portion, described middle Rotary-table is arranged in sunken inside portion, the outer wall of described large Rotary-table and middle Rotary-table joint is provided with side projections, and the center of described side projections offers side opening; The lower end surface of described large Rotary-table radially extends to form four symmetrical bottom protrusion along it, and the center of described bottom protrusion offers and is fixedly connected with hole; The center of described large Rotary-table offers inferior pyramidal hole, the center of described middle Rotary-table offers middle cone shape hole, the center of described little Rotary-table offers upper conical hole, described upper conical hole, middle cone shape hole, inferior pyramidal hole communicate, the aperture in described upper conical hole, middle cone shape hole, inferior pyramidal hole increase gradually and tapering consistent; Side opening in described side projections communicates with middle cone shape hole.
The center flange that the utility model provides, when in use, coaxial large Rotary-table, middle Rotary-table and the little Rotary-table connecting of one, and the heart is offered therein upper conical hole, middle cone shape hole, inferior pyramidal hole, make the bearing can be more flexible when in use.And due to the aperture in upper conical hole, middle cone shape hole, inferior pyramidal hole increase gradually and tapering consistent, when making to use more flexibly and the inwall of bearing and flange can not produce larger friction, reduce wear, extend its service time.Four projections of bottom are that projection is fixedly connected with opponent's part.And the outer wall of large Rotary-table and middle Rotary-table joint is provided with side projections, the center of described side projections offers side opening, side opening communicates with middle cone shape hole, make whole projection to be fixed from medium position by side opening, thereby make the fixing more firm stable of whole projection, difficult drop-off.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Illustrate embodiment below in conjunction with Fig. 1:
As shown in Figure 1, a kind of center flange, described center flange includes coaxial large Rotary-table 1, middle Rotary-table 2 and the roundlet stage body 3 connecting of one, the upper-end surface of large Rotary-table 1 is provided with sunken inside portion 4, described middle Rotary-table 2 is arranged in sunken inside portion 4, the outer wall of described large Rotary-table 1 and middle Rotary-table 2 joints is provided with side projections 5, and the center of described side projections 5 offers side opening 6; The lower end surface of described large Rotary-table 1 radially extends to form four symmetrical bottom protrusion 7 along it, and the center of described bottom protrusion 7 offers and is fixedly connected with hole 8; The center of described large Rotary-table 1 offers inferior pyramidal hole 11, the center of described middle Rotary-table 2 offers middle cone shape hole 21, the center of described roundlet stage body 3 offers upper conical hole 31, described upper conical hole 11, middle cone shape hole 21, inferior pyramidal hole 31 communicate, the aperture in described upper conical hole 11, middle cone shape hole 21, inferior pyramidal hole 31 increase gradually and tapering consistent; Side opening 6 in described side projections 5 communicates with middle cone shape hole 21.
The center flange that the utility model provides, when in use, coaxial large Rotary-table, middle Rotary-table and the little Rotary-table connecting of one, and the heart is offered therein upper conical hole, middle cone shape hole, inferior pyramidal hole, make the bearing can be more flexible when in use.And due to the aperture in upper conical hole, middle cone shape hole, inferior pyramidal hole increase gradually and tapering consistent, when making to use more flexibly and the inwall of bearing and flange can not produce larger friction, reduce wear, extend its service time.Four projections of bottom are that projection is fixedly connected with opponent's part.And the outer wall of large Rotary-table and middle Rotary-table joint is provided with side projections, the center of described side projections offers side opening, side opening communicates with middle cone shape hole, make whole projection to be fixed from medium position by side opening, thereby make the fixing more firm stable of whole projection, difficult drop-off.
