Description
Technical Field
The utility model relates to a single-screw pump, concretely relates to take transmission part of detachable flexible even axostylus axostyle for single-screw pump.
Background
At present, in the fields of food processing and chemical industry, particularly in the transportation of anode and cathode materials and electrolyte in the lithium battery manufacturing industry, the non-pulsation accurate quantitative transportation is required from aqueous liquid to high-viscosity liquid and high-viscosity slurry. The conveying equipment has high requirements in the process of conveying the materials, dead corners are not allowed to store dirt and dirt, and a single-screw pump with a flexible connecting shaft rod is selected in the modern process. The transmission part is the core part of the single screw pump equipment, and the stator and the rotor are closely matched in the operation process of the transmission part of the single screw pump, so that the rotor is easy to wear and needs to be replaced regularly. The transmission component generally consists of three parts: the transmission component with the flexible connecting shaft rod in the traditional structure is connected with the three parts in a hot-mounting mode; when the rotor is worn and needs to be maintained and replaced, the whole transmission part needs to be replaced completely due to the fact that the transmission part of the hot assembly can not be disassembled, the whole single-screw pump needs to be disassembled so that the transmission part can be taken out, time and labor are wasted when a user maintains the single-screw pump, the cost is high, the extension shaft and the connecting shaft rod which are not damaged can not be reused, and waste is serious.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem that the traditional transmission part with a flexible connecting shaft rod cannot be disassembled after being assembled, the utility model provides a transmission part with a detachable flexible connecting shaft rod for a single-screw pump.
In order to solve the above problem, the utility model discloses a technical scheme be:
a transmission part with a detachable flexible connecting shaft rod for a single-screw pump mainly comprises a rotor, the flexible connecting shaft rod and an extension shaft, wherein the front end and the rear end of the flexible connecting shaft rod are respectively provided with left-handed coarse thread, the front end of the rotor is axially provided with an internal thread hole matched with the left-handed coarse thread, and the rear end of the flexible connecting shaft rod is screwed into the internal thread hole to be in threaded connection with the rotor; the rear end of the extension shaft is axially provided with an internal thread hole matched with the left-handed coarse thread, and the front end of the flexible connecting shaft rod is screwed into the internal thread hole to be connected with the extension shaft through threads.
Furthermore, a radial set screw is arranged at the threaded connection part of the front end of the rotor and the rear end of the flexible connecting shaft rod.
Furthermore, a radial set screw is arranged at the threaded connection part of the rear end of the extension shaft and the front end of the flexible connecting shaft rod.
Compared with the prior art, the beneficial effects of the utility model are that:
when the utility model is adopted, the parts can be detached and replaced independently according to the maintenance requirement when the products need to be maintained and replaced, which is simple and convenient; compared with a flexible connecting shaft rod transmission component in a traditional hot-assembling mode, the flexible connecting shaft rod transmission component saves a large amount of cost, saves time and labor, and avoids unnecessary waste. The production cost of the user can be effectively reduced. The utility model discloses a flexible even axostylus axostyle both ends adopt left-handed screw, and with whole pump operation opposite direction, avoided the risk that the pump operation in-process screw thread pine takes off. Set screw has been increased at threaded connection position radial direction, has effectively prevented that the screw thread from taking off to exert the pretightning force that is greater than whole pump starting torque when the assembly, prevent that the motor reversal from causing the unexpected condition that the screw thread takes off when whole pump installation and debugging, safe and reliable in practical application.
Drawings
FIG. 1 is a schematic structural diagram of the present invention;
fig. 2 is a partially enlarged view of fig. 1 according to the present invention.
In the figure: 1. a rotor; 2. a flexible connecting shaft rod; 3. an extension shaft; 4. and (5) tightening the screw.
Detailed Description
The invention will be further explained and explained with reference to the drawings;
a drive unit with detachable flexible connecting shaft lever used for single screw pump, mainly by the trochanter 1, flexible connecting shaft lever 2, extension shaft 3 three parts make up, the front, rear end of the flexible connecting shaft lever 2 is processed into the coarse thread of left-handed thread respectively, the front end axial processing of the trochanter 1 is the female screw hole matching with coarse thread of left-handed thread, the rear end of the flexible connecting shaft lever 2 is screwed into the female screw hole and screwed to connect with trochanter 1; the rear end of the extension shaft 3 is axially processed into an internal thread hole matched with the left-handed coarse thread, and the front end of the flexible connecting shaft rod 2 is screwed into the internal thread hole to be connected with the extension shaft 3 through threads. The screw thread of screwing during the assembly, apply the pretightning force that is greater than whole pump starting torque, prevent that the motor short time reversal from causing the condition emergence that the screw thread pine takes off when debugging installation. The processing of the internal thread hole department of rotor front end has radial screw hole, the screw thread department of flexible even axostylus axostyle rear end is opened has the screw hole corresponding with this radial screw hole, behind the internal thread hole of the rear end screw in rotor front end of flexible even axostylus axostyle 2, to the screw thread hole of the interior screw in holding screw 4 of radial screw hole and continue the rotation and stretch into the screw hole of flexible even axostylus axostyle, equally, at the front end screw thread department of flexible even axostylus axostyle 2, it has corresponding radial hole to open on the 3 screw holes of extension axle, both connect soon to radial screw.
When the transmission component is used, the transmission component is applied to a single-screw pump, the rotor 1 is positioned in a stator of the single-screw pump, the flexible connecting shaft rod 2 is positioned in a pump body of the single-screw pump, the extension shaft 3 is connected with a transmission shaft of the single-screw pump, the rotating direction of the whole pump is opposite to the rotating direction of threads of the transmission component when the whole pump normally operates, the situation that the threads are loosened during operation is avoided, and the transmission component after assembly can be independently disassembled according to maintenance requirements. The device is at on-the-spot actual motion in-process, the phenomenon of reversal probably can take place, and the screw thread pine takes off when preventing the reversal, threaded connection position radial direction has increased holding screw 4, further fixes the position of flexible even axostylus axostyle 2, and the risk that the screw thread pine takes off can simply effectually be avoided.
