Abstract
The invention discloses a screw pump universal joint. The screw pump universal joint comprises a rotor, a connecting block, and an intermediate shaft; the left and the right sides of the connecting block are provided with two connecting sleeves respectively; the outer rings of the two connecting sleeves are provided with two sealing sleeves respectively; the outer rings of the sealing sleeves are provided with locked throat bands; and the connecting sleeves are connected with the rotor and the intermediate shaft respectively through connecting pins. The structure of the screw pump universal joint is reasonable; installation is convenient and fast; operational stability is increased greatly; and service life of screw pumps are increased.
Description
Technical field
The present invention relates to the industrial pump field of accessories, relate in particular to and a kind ofly jack shaft and rotor accurately firmly can be connected and transmit rotation torque, the flexible running without the screw pump universal joint at dead angle.
Background technique
At present being connected between the jack shaft of helical rotor pump and rotor or transmission shaft, transmission is all that the end that outer spherical, rotor or transmission shaft are processed in the jack shaft two ends is processed into to endoporus is cylindrical and the spherical bottom surface, by driving pin, connect, make the rotation torque of motor be delivered to rotor by transmission shaft, driving pin, jack shaft, driving pin, fed sheet of a media is gone out medium transport through the engagement rotation of rotor and stator.It is simple that this transmits Connecting format, precision is low, but the difficulty of processing of component is large, machining accuracy is difficult to guarantee, during the pump running, vibrates larger, the increase of very easily wearing and tearing of transmission shaft, jack shaft and epitrochanterian pin-and-hole, driving pin wearing and tearing and easy gross distortion, had a strong impact on the normal operation of pump, shortened the working life in cycle of pump, maintenance cost is high, has had a strong impact on the normal production of enterprise.
Summary of the invention
The purpose of this invention is to provide a kind of simple and reasonable, quick and easy for installation, the screw pump universal joint that can increase substantially operation stability, extend the working life of pump.
The present invention is achieved in that a kind of screw pump universal joint, comprise rotor, contiguous block, jack shaft, it is characterized in that: described contiguous block the right and left is respectively arranged with connecting sleeve, and two connecting sleeve outer rings are provided with stuffing box gland, and the stuffing box gland outer ring is provided with the larynx hoop of locking; Connecting sleeve all is connected by connecting pin with jack shaft with rotor, connecting sleeve.
Contiguous block of the present invention and connecting sleeve are provided with Spielpassung.
Contiguous block of the present invention axially is being provided with orthogonal two pin-and-holes on certain distance.
Connecting sleeve one end of the present invention is provided with circular hole, the other end is provided with square hole.
The present invention is simple and reasonable, quick and easy for installation, has increased substantially operation stability, has extended working life of pump.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
1. rotors in figure, 2. " 0 " RunddichtringO, 3. connecting sleeve, 4. contiguous block, 5. connecting pin, 6. stuffing box gland, 7. shaft block ring, 8. larynx hoop, 9. jack shaft.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
With reference to accompanying drawing, a kind of screw pump universal joint, comprise rotor 1, contiguous block 4, jack shaft 9, it is characterized in that: described contiguous block 4 the right and lefts are respectively arranged with connecting sleeve 3, two connecting sleeve 3 outer rings are provided with stuffing box gland 6, and stuffing box gland 6 outer rings are provided with the larynx hoop 8 of locking; Connecting sleeve 3 all is connected by connecting pin 5 with jack shaft 9 with rotor 1, connecting sleeve 3.Described contiguous block 4 is provided with Spielpassung with connecting sleeve 3.Described contiguous block 4 axially is being provided with orthogonal two pin-and-holes on certain distance.Described connecting sleeve 3 one ends are provided with circular hole, the other end is provided with square hole.During concrete enforcement, the circular hole of connecting sleeve 3 one ends is connected by connecting pin 5, shaft block ring 7 with the cylindrical of rotor 1, jack shaft 9 respectively, the square hole of connecting sleeve 3 one ends adopts Spielpassung to be connected by connecting pin 5, shaft block ring 7 with contiguous block 4, pin-and-hole and connecting pin 5 adopt Spielpassung, then load onto stuffing box gland 6 and form an integral body with 8 lockings of larynx hoop at two groups of connecting sleeve 3 cylindricals.When screw pump turns round, jack shaft 9 with rotor 1 during because of rotor the eccentric throw of eccentric produced all can adjust and bear by connecting sleeve 3 and contiguous block 4, and do not affect the flexibility of connecting sleeve 3 and the rotation of rotor 1, jack shaft 9, thereby the vibration produced because of bias while having reduced pump operation, thereby guaranteed that screw pump has extended the life cycle life-span of pump, adopt this connecting sleeve 3, contiguous block 4, connecting pin 5 and stuffing box gland 6 as the spare part in common use of pump, to exchange, to use, can greatly reduce quantity in stock and the cost of production of accessory.Connecting sleeve of the present invention, contiguous block and connecting pin are easy to machine shaping, stuffing box gland is by the mould one-step die casting, all parts can be guaranteed machining accuracy, it is simple in structure, install, change convenient and swift, can not produce that connecting sleeve, contiguous block, jack shaft and the wearing and tearing of epitrochanterian pin-and-hole increase and connecting pin wearing and tearing and the phenomenon such as can't run well, greatly improve operation stability, the reliability of product, extend the life cycle life-span of pump.
