Description
Technical Field
The utility model relates to an automobile supercharger spiral case, the automobile supercharger spiral case valve coupling mechanism who is used for supporting and fixes a position automobile supercharger spiral case valve specifically says so.
Background
At present, traditional car booster spiral case valve coupling mechanism includes the spiral case, has the valve in this spiral case, has the valve rod on the valve, has the round hole on the spiral case lateral wall that the valve rod corresponds, and this round hole is passed to valve rod one end and is stretched out outside, has the fastening sleeve between the inner wall of valve rod outer wall and round hole, is interference fit between fastening sleeve and round hole. The during operation, the temperature at fastening sleeve position is about 900 degrees, because the expansion ratio of fastening sleeve and volute is different, the interference degree between fastening sleeve and the round hole can reduce under the high temperature, in addition the vibrations of engine lead to traditional car booster spiral case valve coupling mechanism at the during operation, fastening sleeve can axial displacement, drop, cause the support and the location of valve to become invalid.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an automobile supercharger spiral case valve coupling mechanism, this coupling mechanism can not appear supporting and the problem of location inefficacy.
In order to solve the problems, the following technical scheme is provided:
the utility model discloses a car booster spiral case valve coupling mechanism includes the spiral case, has the valve in this spiral case, and the valve has the valve rod, has the round hole on the spiral case lateral wall that the valve rod corresponds, and valve rod one end is passed this round hole and is stretched out outside, has the fastening sleeve between the inner wall of valve rod outer wall and round hole. The spiral case is characterized in that an annular groove is formed in the outer side wall of the fastening sleeve, limiting holes are formed in the spiral case and are tangentially arranged along the annular groove, the limiting holes are communicated with the annular groove, and a limiting pin is arranged between the limiting holes and the annular groove.
One end of the fastening sleeve extends out of the outer end of the round hole, and an annular outer flange extending outwards in the radial direction is arranged at the extending end of the fastening sleeve.
And the extending end of the valve rod is provided with a connecting sheet.
The method has the following advantages that:
because the utility model discloses an annular groove has on car booster spiral case valve coupling mechanism's the fastening sleeve's the lateral wall, has the spacing hole of following the annular groove tangential and arranging on the spiral case, and spacing hole is linked together with the annular groove, and has the spacer pin between transposition hole and annular groove. Utilize the spacer pin to carry on spacingly to the fastening sleeve, under the high temperature and vibrations condition, axial displacement can not take place for the fastening sleeve, ensures that the valve can prepare the location.
Drawings
Fig. 1 is a schematic structural view of a volute valve connecting mechanism of an automobile supercharger according to the present invention;
fig. 2 is an enlarged view of a portion a of fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model discloses a 2 coupling mechanisms of car booster spiral case 1 valve includes spiral case 1, has valve 2 in this spiral case 1, and valve 2 has valve rod 3, has the round hole on the spiral case 1 lateral wall that valve rod 3 corresponds, and this round hole is passed to valve rod 3 one end and is stretched out outside, and has connection piece 4 on the overhanging end of valve rod 3, has fastening sleeve 6 between the inner wall of valve rod 3 outer wall and round hole. The outer side wall of the fastening sleeve 6 is provided with an annular groove 5, the volute 1 is provided with a limiting hole 8 which is tangentially arranged along the annular groove 5, the limiting hole 8 is communicated with the annular groove 5, and a limiting pin 7 is arranged between the limiting hole 8 and the annular groove 5.
For the convenience of installation, one end of the fastening sleeve 6 extends out from the outer end of the circular hole, and the extended end of the fastening sleeve 6 is provided with an external annular flange 61 extending radially outwards.
The outer side wall of a fastening sleeve 6 of the connecting mechanism of the valve 2 of the automobile supercharger volute 1 is provided with an annular groove 5, the volute 1 is provided with a limiting hole 8 which is tangentially arranged along the annular groove 5, the limiting hole 8 is communicated with the annular groove 5, and a limiting pin 7 is arranged between the transposition hole and the annular groove 5. Utilize spacer pin 7 to carry out spacingly to fastening sleeve 6, under the high temperature and vibrations condition, fastening sleeve 6 can not take place axial displacement, ensures that valve 2 can prepare the location.
