Description
Technical field
The utility model belongs to the mechanical actuation device field, more specifically says the driving structure that relates to a kind of seal arrangement.
Background technique
Seal arrangement is applied in the water-tight equipment peculiar to vessel, seal arrangement rotatingshaft one end connects driving machine (as diesel engine), the other end connects working group's (as propeller cavitation), in order to guarantee sealing, seal arrangement is followed rotatingshaft and is rotated together, therefore the connection between seal arrangement and the rotatingshaft (driving structure) is had very high requirement.The driving structure of mechanical seal device of the prior art, as shown in Figure 1, with punch machining process on existing driving shell 10, go out several semicircles or rectangular lug 11, equally, the excircle place on sealing rotating ring 14 has also opened shape, quantity and the driving shell 10 upper lug 11 corresponding notches that match, be provided with the gap between lug 11 and the notch, can realize moving axially and circumferentially spacing.Direction shown in Figure 1, at the right-hand member place that drives shell 10, be provided with screw hole 12, in application, drive shell 10 and utilize the Cock screw 13 in the screw hole to withstand rotatingshaft 15, cause driving shell 10 to be unified into an integral body, again in conjunction with above-mentioned lug 11 and notch with rotatingshaft 15, make sealing rotating ring 14 rotate, thereby realized driving purposes with rotatingshaft 15.
The driving structure mechanical seal device of above-mentioned prior art has the following disadvantages in actual applications:
(1), when processing lug, easily causes distortion to driving shell; In practice, when processing this lug, adopt punch press to process mostly,, be shaped in a flash, drive shell and be subjected to a stress, cause its distortion because the impact force of punch press is bigger.
(2), driving is not too reliable; Owing to driven the wall thickness of shell and the technology fillet of drawing influences, lug 11 degree of depth of going out there has been certain restriction, big technology circle or shallow lug 11 all can cause to drive and lose efficacy.
(3), driving easily damages the rotatingshaft surface; The road drives shell and utilizes the Cock screw in the screw hole to withstand rotatingshaft from the above, causes driving shell and rotatingshaft to be unified into an integral body, utilizes its lug again, drives the sealing rotating ring and rotates with axle, thereby realized driving purposes.Because Cock screw withstands rotatingshaft, can increase the distortion power of rotatingshaft, even it is deformed, damage rotatingshaft.
The model utility content
The technical problem that the utility model solved is: a kind of driving structure of not damaging the rotatingshaft surface and driving reliable seal arrangement is provided.
The technological scheme that the utility model adopted is: a kind of driving structure of seal arrangement, it comprises rotatingshaft, driving casing and is positioned at sealing rotating ring, the spring that the driving casing axial direction is arranged in order from inside to outside and puts the spring seat that holds spring that it is characterized in that: it also comprises a slice driving plate and at least one arc card article at least; Described driving plate is longer than driving casing; Described sealing rotating ring outer round surface is provided with at least one first groove, and described spring seat outer round surface is provided with at least one the 3rd groove, and described first groove and the 3rd groove all match with driving plate thickness; Driving plate one end side surface is provided with short slot, and described short slot and arc card article match; Driving casing one end inwall is provided with the annular indent that matches with arc card article shape, and described arc card article thickness is greater than the degree of depth of annular indent; Driving casing the other end inwall is provided with an annular protrusion; The outer circular section of described sealing rotating ring is stepped, forms first cylindrical and second cylindrical, and the described first cylindrical external diameter is less than the annular protrusion internal diameter, and the outer warp of second cylindrical is greater than the annular protrusion internal diameter.Also be provided with flat gasket between described sealing rotating ring and the spring.Described flat gasket outer round surface is provided with and first groove and the second same groove of the 3rd groove.Described first groove, second groove and the 3rd groove three's groove central lines.Described driving plate is two length of a film square drive sheets.Described arc card article is two semicircle arc card articles.
The utility model is to install like this: at first, to seal rotating ring, seal arrangement (seal ring), flat gasket, spring, spring seat is enclosed within on the rotatingshaft successively, owing to be equipped with the groove that matches with driving plate on sealing rotating ring, flat gasket, the spring seat, groove on sealing rotating ring, flat gasket, the spring seat all aligns, so driving plate can insert in the groove that seals on rotating ring, flat gasket, the spring seat, it is in aggregates to comprise that spring connects.Moreover this integral body is inserted in the driving casing and since on the sealing rotating ring external diameter of second cylindrical than in the annular protrusion of driving casing through big, so this integral body finally can not drop out driving casing.At this moment, driving plate one end withstands on the driving casing annular protrusion, because driving casing the other end length direction is provided with a short slot, two sections arc card articles and two driving plates are combined into a circle, just in time match with the annular indent in the driving casing, owing to the degree of depth of arc card article thickness greater than annular indent, so an arc card article part is outside annular indent, at this moment, this part blocks main driving plate to the arc card article outside annular indent.Whole like this device just has been integral.The length of the big driving casing of the length of driving plate, therefore, being positioned at the outer driving plate of driving casing just becomes other rotatingshafts of connection.Thereby driving whole sealing device rotates.
The beneficial effects of the utility model are: by driving casing and arc card article sealing move, flat gasket, spring and spring seat be unified into holisticly, the driving plate that stretches out connects and drives rotating shaft, does to drive and uses.That is, driving whole sealing device by driving plate rotates.Therefore, needn't push lug, also needn't on driving casing, beat tapped hole, not need driving casing and rotatingshaft to be fixed up by screw to driving casing.Therefore also just solved the problem of passing through the screw rotatingshaft in the prior art.
As improvement, also be provided with flat gasket between described sealing rotating ring and the elastic device.Give better Point of Strength of spring, that is, will seal that the rotating ring bullet is crowded to be opened.
As improvement, described driving plate is two length of a film square drive sheets, helps driving putting forth effort.
As improvement, described arc card article is that two semicircle arc card articles and two driving plates can be combined into a circle.
