Description
Technical Field
The utility model relates to the field of mechanical sealing devices, in particular to a positioning sleeve for mechanical sealing.
Background
The mechanical seal structure is composed of only two components: a rotating component and a stationary component. The whole structure of the mechanical seal is represented by a single-end-face seal, a non-balanced type, a random rotation direction and a rubber corrugated pipe. The mechanical seal working principle is that the moving ring is pushed by a rubber corrugated pipe arranged in a rotating part on the shaft, the rubber corrugated pipe is not only a secondary sealing element, but also a driving element of the moving ring, so that the joint of the static ring is achieved, and the end face seal for preventing the fluid in the pump from leaking along the axial direction is realized. For example, a chinese utility model patent with publication number CN203627292U discloses a mechanical seal structure for a pump, which includes a rubber bellows sleeved on a rotating shaft, wherein one end of the rubber bellows close to the pump cover is provided with a ring groove, a moving ring is embedded in the ring groove, steps are respectively formed at positions of the outer side of the rubber bellows close to the two ends, the steps are respectively provided with a front spring seat and a rear spring seat, and a spring for applying elastic force to the front spring seat and the rear spring seat is sleeved at a position of the outer side of the rubber bellows between the front spring seat and the rear spring seat; a static ring is arranged in the pump cover, and a radial sealing element is arranged between the static ring and the pump cover. The utility model discloses in be provided with the spring holder of similar position sleeve effect equally, the spring holder of both sides does not have the cooperation, and then leads to the connection between the part inseparable, when the rotating ring subassembly rotates along with the pump shaft, the unsatisfactory condition of sealed easily appears.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a positioning sleeve for mechanical sealing. The utility model can achieve good positioning effect and improve the connection tightness of parts.
The technical scheme of the utility model is as follows: the utility model provides a position sleeve for mechanical seal, includes the holding ring physique, and the one end of the location ring body is equipped with the holding ring piece that extends to the inboard, evenly is equipped with the location tooth that extends to the outboard on the holding ring piece, forms the draw-in groove between the location tooth.
In the above-described positioning sleeve for mechanical seal, the positioning teeth are inclined toward the center.
In the positioning sleeve for mechanical sealing, the inclination angle of the positioning teeth is 1 to 3 °.
In the positioning sleeve for mechanical sealing, a transition arc structure is formed between the positioning ring body and the positioning ring sheet.
Compared with the prior art, the utility model has the following advantages:
1. the positioning ring comprises a positioning ring body, wherein one end of the positioning ring body is provided with a positioning ring sheet extending inwards, positioning teeth extending outwards are uniformly arranged on the positioning ring sheet, and clamping grooves are formed among the positioning teeth; the positioning ring body is sleeved on the corresponding movable ring rubber, two positioning sleeves need to be arranged in practical application, the two positioning sleeves are correspondingly arranged, and the positioning teeth on one side correspond to the clamping grooves on the other side; through the improvement of the structure, the utility model can play a good positioning effect and improve the connection tightness of the components.
2. The positioning teeth incline towards the center, the positioning teeth are arranged to be in an inclined structure, the positioning teeth of the pair of positioning sleeves are in contact with each other, the close contact between the parts is further enhanced, and the stability of the movable ring assembly during rotation is ensured; meanwhile, the inclined positioning teeth are matched with the clamping grooves, so that the contact area can be increased, the stability of matching is improved, pressing force can be generated on the moving ring rubber, and the moving ring rubber is more compact and stronger in linkage.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a cross-sectional view of the present invention.
Description of the reference symbols in the drawings: 701-positioning annular body, 702-positioning annular sheet, 703-positioning tooth and 704-clamping groove.
Detailed Description
The utility model is further illustrated by the following figures and examples, but is not to be construed as being limited thereto.
Example (b): a locating sleeve for mechanical sealing comprises a locating ring body 701, a locating ring sheet 702 extending inwards is arranged at one end of the locating ring body 701, locating teeth 703 extending outwards are evenly arranged on the locating ring sheet 702, and a clamping groove 704 is formed between the locating teeth 703. Positioning teeth in the two positioning sleeves are matched with the clamping grooves and correspond to the clamping grooves, so that the movable ring assembly is driven to rotate along with the shaft body, the annular groove and the positioning protrusion are arranged on the outer side of the movable ring rubber, the positioning sleeves can be accurately clamped in the movable ring rubber, the movable ring rubber is prevented from moving in the axial direction, and meanwhile, the connection tightness between parts is enhanced; the positioning teeth 703 incline towards the center, the positioning teeth are arranged to be in an inclined structure, the positioning teeth of the pair of positioning sleeves are abutted, the close contact between the parts is further enhanced, the stability of the movable ring assembly during rotation is ensured, and the inclination angle of the positioning teeth 703 is 1-3 degrees; the positioning ring body 701 and the positioning ring piece 702 are in a transition arc structure, the rubber elasticity of the moving ring can be improved by arranging the arc transition structure, the plasticity of the body of the moving ring is improved, and the positioning ring can be attached more tightly when the positioning sleeves are connected.
The working principle of the utility model is as follows: the positioning ring body is sleeved on the corresponding movable ring rubber, two positioning sleeves need to be arranged in practical application, the two positioning sleeves are correspondingly arranged, and the positioning teeth on one side correspond to the clamping grooves on the other side; through the improvement of the structure, the utility model can play a good positioning effect and improve the connection tightness of the components.
