Abstract
The utility model discloses a kind of second Sealing of round table-like rotary-piston type working machine, its structure comprises the second Sealing, and described second Sealing is in the form of annular discs, and the radius of the cross section of described second Sealing in the form of annular discs changes with the trend of axle.The radius at described second Sealing two ends in the form of annular discs is different.The beneficial effects of the utility model are: structure is simple and can effectively be sealed by the circular groove of rotary-piston type working machine first Sealing.
Description
Technical field
The utility model relates to a kind of Sealing, particularly relates to a kind of second Sealing of rotary-piston type working machine.
Background technique
Application number be 2014208050362 invention be a kind of rotary-piston type working machine, the outer being arranged on discoid second Sealing in block mount inlet in this inventive embodiments 2,5,6,7 must contact with the first Sealing, and the circular groove location contacts of the second Sealing and the first Sealing is to prevent the gas in cylinder body from can pass through from the position between the second Sealing and the first Sealing.Be the disc radius size of the right and left of the disk in the invention of 2014208050362 at application number be identical, the shortcoming of this discoid second Sealing is: sealing effect is undesirable.Because the circular groove of the first Sealing is that the groove of ringwise groove instead of straight line is so only have the cutting profile line cutd open by the radial direction in axle center to be only circular arc line when carrying out cutting to circular groove.The disk of the second Sealing has certain thickness, so the circular groove of the second Sealing and the first Sealing cannot carry out face sealing and can only carry out linear sealing; Again due to the normal of the circular groove of the first Sealing and the normal of the second Sealing mutually vertical, so the disk of the second Sealing can not be columned disk and can only be that the radius value of cross section can only have a place to be maximum discoid.
Summary of the invention
Problem to be solved in the utility model is the second Sealing providing a kind of round table-like rotary-piston type working machine, and its structure is simple and can effectively be sealed by the circular groove of rotary-piston type working machine first Sealing.
In order to overcome the above problems, the technical solution of the utility model is as follows:
Second Sealing of round table-like rotary-piston type working machine, its structure comprises the second Sealing, and described second Sealing is in the form of annular discs, and the radius of the cross section of described second Sealing in the form of annular discs changes with the trend of axle.
The radius at described second Sealing two ends in the form of annular discs is different.
The beneficial effects of the utility model are: structure is simple and can effectively be sealed by the circular groove of rotary-piston type working machine first Sealing.

Fig. 2 is the rear view of Fig. 1.
Fig. 3 is the plan view of Fig. 1.
Fig. 4 is the right elevation of Fig. 1.
Fig. 5 the first Sealing that to be the utility model embodiment with application number be in the invention of 2014208050362 in embodiment 2,5,6 and 7 and transmission shaft coordinate schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figures 1 to 5, it is in the form of annular discs that its structure of the utility model comprises the second Sealing 1, second Sealing 1, and the radius of the cross section of the second Sealing 1 in the form of annular discs changes with the trend of axle.The radius at the second Sealing 1 two ends in the form of annular discs is different.Second Sealing is provided with two piston via holes 10.
The utility model is work like this:
As shown in Figure 5, by the excircle of one end large for the radius of the second Sealing 1, radially coordinate vertical with the circular groove of the first Sealing 2 contacts and seals, and the first Sealing 2 is fixed on transmission shaft 3.First Sealing 2 rotates together with transmission shaft 3, and the second Sealing 1 is around the center axis thereof of itself.
Claims (2)
