Description
Technical field
The present invention relates to a kind of screw thread device for quickly disassembling being applied to shaft coupling water pump, belong to mechanical field.
Background technology
Pump is a kind of a large amount of wide workalike equipment, and it is widely used in oil, chemical industry, electric power, metallurgy, mine, shipbuilding, agricultural and national defence all departments, occupies important status in national economy. Along with the industrial scale in chemical industry and mine is increasing, often needing large discharge water pump to meet conveying requirement, the structure of common water pump is all generally water pump shaft one end is water pump impeller, and the other end is motor power input terminus, is often shaft coupling. Owing to water pump is all generally that long-time continuous is run, so bearing easily damages, change bearing and generally need to first dismantle the shaft coupling of water pump impeller and the other end, but the assembling of existing water pump shaft and water pump impeller, shaft coupling belongs to typical axle, hole shrink-fit, and undertaken carrying transmission by key. The usual requirement on machining accuracy of shrink-fit is higher, and connects in conjunction with key and realize torque bearing function, and assembling generally all needs to load very big squeeze, if not having professional equipment and instrument, dismounts all very inconvenient.
Be threaded have processing simple, assemble convenient, simultaneously also there is unidirectional carrying torque functions, therefore, it is threaded if can adopt in the connection of axle with hole and realizes transmission, make it assembling and dismounting all comparatively convenient, then possess higher practical value and market application foreground. Axle in reality coordinates in transmission Screw assembly with hole, in order to big bearing function demand can be realized, screw thread axle is all relatively big with the scantling of the similar nut member matched, and it is often all also very easily convenient to screw in when assembling, and in use can realize the constantly locking automatically of bearing capacity, thus very reliable, but when dismantling, assembling is very tight often, dismantles very difficult, if simple easy removal can be realized under these conditions, seem particularly important.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, it is provided that a kind of simple and practical screw thread device for quickly disassembling being applied to shaft coupling water pump.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of screw thread device for quickly disassembling being applied to shaft coupling water pump, comprise water pump impeller, bearing, water pump shaft and shaft coupling, it is characterized in that: shaft coupling and water pump shaft and water pump impeller and water pump shaft all adopt Screw assembly, and thread rotary orientation is with the direction of work with carrying auto lock; The similar nut of water pump impeller is by being threaded with water pump shaft and impeller plain washer, copper-lead are reversed composite pad and compressed, and water pump impeller and water pump shaft one end form screw thread and be rigidly connected; Card hoop part is inserted in the water pump shaft the other end, then shaft coupling plain washer is inserted in water pump shaft, then screws in the shaft coupling of similar nut, more rationally all locking, the shaft coupling of card hoop part and similar nut and the water pump shaft the other end is also formed and is rigidly connected.
It is the copper pad that punch process becomes that described copper-lead reverses composite pad, is with fin outside it, then at copper pad both sides compound fusible lead alloy packing ring.
Described card hoop part is made up of card hoop, card hoop ear, card hoop pad and bolt, card hoop cross section is wedge shape, form opening structure by two semicircular ring card hoop bodies, card hoop pad opens oval hole to strengthen axial elasticity, card hoop pad two ends are two dimensional structure, being convenient to coordinate with shaft shoulder plane, card hoop uses bolt through the hole on card hoop ear, is assemblied on card hoop pad and becomes to be integrated.
When the present invention need to dismantle, the copper-lead of innovative design is utilized to reverse composite pad, card hoop part, pass through operation readiness, simply eliminating similar nut member to the pressure of screw shaft shoulder end face, at this moment nut and screw part are in unloading vacant state, take apart and become equally simple and convenient with Screw assembly, for solving Screw assembly continuous auto lock under load effect, the technical barrier not easily dismantled, locks field at large pump shaft components screw thread, and such function seems particularly important.
When water pump impeller needs dismounting but is very difficult, adopt oxy-acetylene flame that copper-lead is reversed the copper pad in the middle of Composition spacer and carry out oxy-acetylene flame heat treated, owing to the thermal conduction of copper is fabulous, and the fusing point of lead alloy is lower, after heating, lead alloy is heated melting, the compression tensioning power of water pump impeller and shaft shoulder step is eliminated completely, makes water pump impeller be in vacant state completely, is easy to dismounting especially.
When similar nut joint member need dismounting but very difficult time, with spanner, bolt is pulled down, cause two semicircular ring card hoop bodies are quick is wedge shape to opening structure and card hoop body cross section, can connect to close up from two card hoop ears with the flat instrument in one end and easily pry open, card is bound round easy removal get off, card hoop pad returns to lax state, tensioning power after the locking of joint member and shaft shoulder end face is eliminated completely, make the joint member of similar nut be in vacant state completely, it is easy to dismounting especially.
The present invention can effectively solve the Screw assembly problem that continuous auto lock is not easily dismantled under load effect, is particularly suitable for the convenient dismounting after the locking of large-scale component screw thread, and effect is particularly remarkable, and compared with prior art, the useful effect of the present invention is also:
1, not changing the feature of Screw assembly, only need to add copper-lead and reverse composite pad, card hoop pad and card hoop, cost is low also to be easy to realize especially; 2, copper-lead reverse composite pad, card hoop pad can play good Stress decomposition effect, effectively strengthen the supporting capacity of structure, card hoop pad is opened oval hole and can effectively be strengthened card and bind round and pad axis elasticity; 3, copper-lead is used to reverse the Assembly And Disassembly of the molten design of composite pad heat with card hoop very cleverly, realize the tensioning of axial accessory and lax function, the effectively quick tensioning power eliminating the locking of similar nut, it is achieved the assembly rapid and convenient dismounting of similar nut member Screw assembly tight especially; 4, card hoop pads and is convenient to repeatedly quick assembly and disassembly use with the wedge shape assembly structure blocking hoop.
