Abstract
The invention relates to a spit coupling with easily replaceable mechanical seals. The spit coupling comprises two axially separated shells, wherein the two shells are provided with bolt holes in corresponding positions. The split coupling is characterized in that a coupling body is arranged at the middle part of the shell, and both ends of the shell are respectively provided with a joint; a cavity for insertion of a shaft is arranged in the joint; the outer half section of the cavity has an inner diameter adapted to the outer diameter of the shaft; the inner half section of the cavity has an inner diameter greater than that of the outer half section; a spacing shoulder is formed on the inner wall of the cavity; a hanger plate is fixed at the end part of the shaft inserted into the cavity through a bolt; and the outer edge of the hanger plate clamps against the spacing shoulder. As the split coupling is composed of two axially separated shells, disassembly and assembly are convenient, and centering performance is good; and as the coupling body can be designed and fabricated with a length corresponding to the height of the mechanical seals, only the coupling needs to be dismounted to conveniently replace the mechanical seals without dismounting a speed reducer, and therefore the operation is convenient, safe and rapid, the labor intensity of workers is alleviated, and the work efficiency is improved.
Description
Technical field
The present invention relates to a kind of coupling that is applied on mixing plant, specifically a kind of a kind of folder coupling of being convenient to change mechanical seal.
Background technique
Mix operation and be the production process commonly used in industrial processes, along with the expansion gradually of commercial production scale, people have higher requirement to the property easy to maintenance of mixing plant.Mechanical seal is vitals on mixing plant, and mechanical seal belongs to easily damaged parts, and the accessory that it just need to more renew after operation a period of time is to guarantee sealability.Just can change after need to removing speed reducer, coupling when changing mechanical seal, such replacing operation labor intensity is large in the past, and longevity of service has a strong impact on manufacturing efficiency.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of folder coupling of simple and ingenious structure is provided, it can fast and easy install and remove mechanical seal, alleviated workman's labor intensity, increase work efficiency, transmitting torque reliably again, and also centring property is good.
According to technological scheme provided by the invention, the folder coupling, comprise two folder shells of subdivision vertically, two folder shells are provided with bolt hole corresponding to position, it is characterized in that: be coupling body in the middle part of described folder shell, two ends are connecting heads, be provided with in connecting head for the chamber that inserts axle, the internal diameter that this chamber is outer half section and the external diameter of axle are suitable, and the internal diameter of half section greater than the internal diameter of outer half section, forms a spacing shoulder on chamber inner wall in this chamber; The end of inserting the axle in chamber has been bolted boatswain chair, and the boatswain chair outward edge blocks described spacing shoulder.
As a further improvement on the present invention, described bolt hole is arranged on the connecting head at folder shell two ends.
As a further improvement on the present invention, the radial dimension of described folder housing two ends connecting head is greater than the radial dimension of middle coupling body, is provided with the transition inclined-plane between connecting head and coupling body.
As a further improvement on the present invention, the interior chamber inner wall of described folder shell two ends connecting head is provided be used to the keyway of setting flat key.
As a further improvement on the present invention, described coupling body center also has axial through hole, and this through hole is coaxial with the chamber in the connecting head of folder shell two ends and be connected.
The present invention compared with prior art, advantage is: (1) the present invention by two vertically the folder shell of subdivision form, easy accessibility, centring property is good; (2) coupling body length of the present invention can be made by the mechanical seal height design, in the situation that do not remove speed reducer, only needs to remove this coupling, just can change easily mechanical seal, easy to operate, safe, quick, alleviated workman's labor intensity, increase work efficiency.
Description of drawings
Fig. 1 is structure of the present invention and uses schematic diagram.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, folder coupling of the present invention mainly by two vertically the folder shell 2 of subdivision form, folder shell 2 middle parts are coupling body 2b, two ends are connecting head 2a, are provided with bolt hole corresponding to position on the connecting head 2a at two folder shell 2 two ends; Be provided with in described connecting head 2a for the chamber 2c that inserts axle, the internal diameter that this chamber 2c is outer half section and the external diameter of axle are suitable, and after axle inserted chamber 2c, two folder shells 2 can and be clamped the axle of insertion by bolt tightening; The internal diameter of half section greater than the internal diameter of outer half section, forms a spacing shoulder 2d on chamber 2c inwall in described chamber 2c; The end of inserting the axle in chamber 2c has been bolted boatswain chair 6, and boatswain chair 6 outward edges block described spacing shoulder 2d.
As shown in Figure 1, in the present invention, the radial dimension of described folder shell 2 body two ends connecting head 2a is greater than the radial dimension of middle coupling body 2b, is provided with the transition inclined-plane between connecting head 2a and coupling body 2b.In addition, described coupling body 2b center also has axial through hole, and this through hole is coaxial with the chamber 2c in folder shell 2 two ends connecting head 2a and be connected.Such structure makes disassembling section convenience, the safety, quick of folder shell 2, has alleviated workman's labor intensity, increases work efficiency.
As shown in Figure 1, the chamber 2c inwall in described folder shell 2 two ends connecting head 2a is provided be used to the keyway of setting flat key.Insert the axle in chamber 2c and press from both sides between shell 2 and can also install flat key additional, connect as auxiliary, transmit axial force and moment of torsion.
Installation applicable cases of the present invention is as shown in Figure 1: the pto＝power take-off of motor reducer 1 inserts in the chamber 2c of two folder shell 2 upper ends and the flat key of packing into, the power input shaft end fixedly mounts boatswain chair 6 by screw, and boatswain chair 6 is stuck on spacing shoulder 2d on chamber 2c inwall.Stirring shaft 3 upper ends are inserted in the chamber 2c of two folder shell 2 lower ends and the flat key of packing into, and stirring shaft 3 ends fixedly mount another piece boatswain chair 6 by screw, and boatswain chair 6 is stuck on spacing shoulder 2d on chamber 2c inwall.
The coupling body 2b that coupling is pressed from both sides in the present invention can arrange longly, increased the space length of motor reducer 1 pto＝power take-off end and stirring shaft 3 upper ends, remove when changing mechanical seal 4, as long as remove the folder coupling, mechanical seal 4 just can make progress smoothly to be provided with from stirring shaft 3(stirring shaft 3 and put coil apparatus, tenesmus with restriction stirring shaft 3) and in frame 5 take out, it is convenient to change.
