Description
Technical field:
The utility model relates to the bar linkage structure of a kind of high pressure, big flow helical rotor pump, adopts Rzeppa type Universal linking lever structure, and this structure is wear-resisting, bearing capacity is big.
Background technique:
Along with the expansion of expanding economy and userbase, industries such as oil field, water coal slurry, chemical industry need the flow of helical rotor pump increasing, pressure is more and more higher.And the major obstacle of restriction high pressure, big flow helical rotor pump development is a bar linkage structure, because high-pressure high-flow pump power demand is very big, the universal joint connecting rod not only transmits very big moment of torsion, and bear very big axial force and oscillatory forces, the wearing and tearing of pin axle type universal joint bearing pin are very serious, often fracture influence operation.
The model utility content:
The technical problem that solves
For fear of the deficiencies in the prior art part, the bar linkage structure of a kind of high pressure that the utility model provides, big flow helical rotor pump is a kind of wear-resisting, the Rzeppa type Universal linking lever knot that bearing capacity is big.
Technological scheme:
Technical characteristics of the present utility model is: comprise connecting rod 9, universal socket 4, it is characterized in that: several ball-and-sockets of processing on the bulb of the two ends of connecting rod 9, some holes that processing equates with several ball-and-sockets on universal socket 4, dress plurality of steel balls 3 correspondingly between them.On universal socket 4 end faces, process boss,, universal socket 4 is packed in rotor 1 and the transmission shaft 10, gland 6, universal socket 4, rotor 1 or transmission shaft 10 are coupled together with bolt 8 at rotor 1 and transmission shaft 10 end faces processing trough.
Design back spherical bearing 2 between connecting rod 9 and universal socket 4, back spherical bearing 2 material selection MC nylon or polyphenyl thioether composite materials.
Transmission shaft 10 can also be designed to hollow, and connecting rod 9 is passed from Hollow Transmission Shafts 10, and connecting rod 9 is connected in the speed reducing transmission case back with transmission shaft 10.On transmission shaft 10 ear end faces, slot, universal socket 4 is inserted.
Beneficial effect
The invention has the beneficial effects as follows: owing to adopt the very high plurality of steel balls transmitting torque of hardness, bear axial force, transmitting torque and the part that bears axial force are born by two parts respectively, improved the force-bearing situation of part like this with the back spherical bearing.Back spherical bearing material selection polyphenyl thioether composite material makes that this structure is wear-resisting, bearing capacity is big, and using effect is fine, and the connecting rod life-span is more than 10000 hours.

Embodiment
Now in conjunction with the accompanying drawings the present invention is further described:
Embodiment 1, sees the structure of accompanying drawing 1: processing 6 or 8 ball-and-sockets on connecting rod 9 two ends bulbs, and processing 6 or 8 holes on universal socket 4, dress steel ball 3 between them, the steel ball 3 that moves through of connecting rod 9 passes to universal socket 4.On universal socket 4 end faces, process boss, at rotor 1 and transmission shaft 10 end faces processing trough, universal socket 4 is packed in rotor 1 and the transmission shaft 10, with bolt 8 gland 6, universal socket 4, rotor 1 or transmission shaft 10 are coupled together, by universal socket boss transmitting movement.The transmission of moment of torsion: transmission shaft 10 → universal socket 4 → steel ball 3 → connecting rod 9 → steel ball 3 → universal socket 4 → rotor 1.The vital part of transmitting torque is universal socket 4 (see figure 3)s, and the plum blossom hole of this part not only bears very big peripheral force, and steel ball swings in the hole, so the Bearing Steel Gr15 that universal socket material selection wear resistance is fine, intensity is very high quenches.Axial force is born by back spherical bearing 2, and the axial force of high-pressure high-flow pump is very big, and between back spherical bearing 2 spheres and connecting rod 9 bulbs relative movement is arranged, and lubricity is very poor again, thus require the spherical bearing material withstand voltage, wear-resisting, good self lubricity arranged.In low-pressure and medium temperature during less than 70 ℃, back spherical bearing 2 material selection MC nylon, this material self lubricity is good, friction factor is little, absorbing, not seize, good wear-resisting, antifriction, heat resistance arranged, have certain mechanical strength.When high pressure and high temperature media, because MC nylon reduction in strength when high temperature is very fast, do not satisfy usage requirement, therefore spherical bearing 2 material selection polyphenyl thioether composite materials after, that is: 50% polyphenylene sulfide+(25～30) % glass fibre+(15～20) % teflon, these material property characteristics: have high strength under the high temperature, creep resistant is good, self lubricity is good, wear resistance performance is good.
Embodiment 2, see the structure of accompanying drawing 2: for shortening the length of high-pressure high-flow pump, connecting rod 9 is passed from Hollow Transmission Shafts 10, connecting rod 9 is connected in the speed reducing transmission case back with transmission shaft 10.See Fig. 2, on transmission shaft 10 ear end faces, slot that universal socket 4 is inserted, and transmission shaft 10 passes motion to connecting rod 9 by universal socket 4, steel ball 3.The axial limiting of connecting rod is by forward and backward spherical bearing, and preceding spherical bearing 5 is contained in the transmission shaft 10, and back spherical bearing 2 is packed in the rear end cover 12, with bolt 8 rear end cover 12, universal socket 4, transmission shaft 10 is fixed together.
