Abstract
The utility model discloses a universal joint of a screw pump. The universal joint comprises a rotor, a connecting block and a middle shaft, wherein connecting sleeves are respectively arranged on left and right sides of the connecting block; sealing sleeves are arranged on outer rings of the two connecting sleeves; locked hose clamps are arranged on the outer rings of the sealing sleeves; the connection between the connecting sleeves and the rotor, and the connecting sleeves and the middle shaft are achieved through connecting pins. The universal joint is simple and reasonable in structure, and convenient and rapid to mount, the operation stability is greatly improved, and the service life of the pump is prolonged.
Description
Technical field
The utility model relates to industrial pump field of accessories, relate in particular to a kind ofly jack shaft accurately firmly can be connected and transmit rotation torque with rotor, flexibly running is 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 to be processed into endoporus be cylindrical and spherical bottom surface for one end that outer spherical, rotor or transmission shaft are processed into in jack shaft two ends, 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, vibrates larger during pump running, the increase of very easily wearing and tearing of transmission shaft, jack shaft and epitrochanterian pin-and-hole, driving pin wearing and tearing and easily 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 utility model 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, extends the working life of pump.
The utility model is achieved in that 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, two connecting sleeve outer rings are provided with stuffing box gland, and stuffing box gland outer ring is provided with the larynx hoop of locking; Connecting sleeve is all connected by connecting pin with jack shaft with rotor, connecting sleeve.
Contiguous block described in the utility model and connecting sleeve are provided with Spielpassung.
Contiguous block described in the utility model is axially being provided with orthogonal two pin-and-holes on certain distance.
Connecting sleeve described in the utility model one end is provided with circular hole, the other end is provided with square hole.
The utility model is simple and reasonable, quick and easy for installation, has increased substantially operation stability, has extended working life of pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
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
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing, screw pump universal joint, comprises 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 is all 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 is axially being provided with orthogonal two pin-and-holes on certain distance.Described connecting sleeve 3 one end are provided with circular hole, the other end is provided with square hole.During concrete enforcement, the circular hole of connecting sleeve 3 one end 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 end 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 in aggregates with larynx hoop 8 locking shapes 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 producing 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 having 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 utility model, contiguous block and connecting pin are easy to machine shaping, stuffing box gland is by 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 cannot run well, greatly improve operation stability, the reliability of product, extend the life cycle life-span of pump.
