Abstract
The utility model belongs to an improvement of a mechanical seal structure and especially relates to cutting sleeve type multi-spring mechanical seal comprising a rotating ring and a static ring. A cutting sleeve type spring seat is connected with a rotating ring seat via buckling hooks on symmetrical buckling arms on the cutting sleeve type spring seat; the rotating ring is disposed in a concave platform on the external end of the rotating ring seat; springs are installed in seat holes evenly distributed on the cutting sleeve type spring seat; the springs are cooperated with the rotating ring seat; and the rotating ring is cooperated with the static ring. The cutting sleeve type multi-spring mechanical seal is rationally structured; great seal performance cannot only be kept, but the springs are prevented from twisting during high speed rotation of a rotating shaft, so great friction auxiliary application property is provided; and the cutting sleeve type multi-spring mechanical seal possesses excellent sliding property, good connection performance and convenient installation.
Description
Technical field
The utility model belongs to the improvement of mechanical seal structure, the particularly many spring mechanical sealings of a kind of FERRULETYPE.
Background technique
Many spring mechanical sealings claim again little spring mechanical seal, and this structure axial dimension is less, and the method for available change number of springs changes elastic force, and axial force is more even, are applicable to high speed machine sealing, simple and reliable, especially in large diameter mechanical seal.Shortcoming is that spring has the trend being distorted under high revolution, causes the skewness of liquid film on sealing surface.Spring palpus and axle journal coupling, for manufacturing and using, interchangeability is bad.
Model utility content
The purpose of this utility model is to provide a kind of FERRULETYPE many spring mechanical sealings, and it is rational in infrastructure, can not only keep good sealability, and rotatingshaft is non-warping at high rotating speed lower spring, can make friction pair stickiness good, has good sliding, switching performance is good, easy for installation.
The purpose of this utility model is achieved in that the many spring mechanical sealings of a kind of FERRULETYPE, comprise rotating ring and stationary ring, FERRULETYPE spring seat is connecting rotating seat by the grab on the card arm of its symmetry, in the concave station of rotating seat outer end, coordinate rotating ring is installed, the uniform seat of the many spring seats of FERRULETYPE is installed with respectively spring in hole, spring matches with rotating seat, and rotating ring matches with stationary ring.
The feature of the many spring mechanical sealings of FERRULETYPE has:
1, adopt shift fork transmission, the gap of shift fork is 0.5mm, this driving mechanism, and transmission performance is good, and the performance that slides axially is strong.
2, axial dimension and radial dimension are all little than similar many springs.Can use the device that multiple Seal cage is less.
3, in order to allow spring not be distorted, specially design spring base hole under rotating speed.Spring base hole one can prevent the distortion of spring, and two can make friction pair stickiness follow.
The Placement of spring seat and rotating ring is FERRULETYPE.Cutting ferrule connection is convenient, and switching performance is good.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model will be further described, Fig. 1 is sectional structure schematic diagram of the present utility model, Fig. 2 is the main TV structure schematic diagram of spring seat, Fig. 3 is the A-A sectional structure schematic diagram of Fig. 2, Fig. 4 is the B-B sectional structure schematic diagram of Fig. 5, Fig. 5 is the D-D sectional structure schematic diagram of Fig. 4, and the C that Fig. 6 is Fig. 5 is to view.
Embodiment
The many spring mechanical sealings of a kind of FERRULETYPE, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, comprise rotating ring 4 and stationary ring 5, FERRULETYPE spring seat 1 is connecting rotating seat 3 by the grab 7 on the card arm 8 of its symmetry, in the concave station of rotating seat 3 outer ends, coordinate rotating ring 4 is installed, in the uniform seat hole of the many spring seats 1 of FERRULETYPE, spring 2 is installed respectively, spring 2 matches with rotating seat 3, and rotating ring 4 matches with stationary ring 5.The right-hand member of FERRULETYPE spring seat 1 is arranging two symmetrical outwardly directed card arms 8, is arranging to projecting inward grab 7 in the outer end of card arm 8; Two symmetrical open recess 6 are being set on the external cylindrical surface of rotating seat 3, the keyway 11 matching with the grab 7 of FERRULETYPE spring seat card arm is being set on the bottom surface of open recess 6.Between spring 2 outer ends and rotating seat 3 end faces, packing ring 10 is being set.On the outer peripheral surface of FERRULETYPE spring seat 1, radial equipartition is arranging three positioning screw holes 9.
