Abstract
A kind of small-bore electric submersible screw pump speed reducer eccentric drive shaft, solve the problem of small-bore electric submersible screw pump speed reducer driving shaft hydraulic performance decline, comprise transmission shaft body, its special way is: the middle part of described transmission shaft body is respectively equipped with the eccentric body be integrated with transmission shaft body from front to back, and two eccentric bodies misplace layout up and down.Transmission shaft is replaced to replace the Split type structure of speed reducer driving shaft, eccentric bushing and key by the eccentric drive shaft of integrative-structure.Operationally, because eliminate eccentric bushing and key, eccentric drive shaft need not spline, and increase compared with in the of 7% with diameter of axle when offering a keyway, overall performance improves 10%, improves the power of transmission.
Description
Technical field
The utility model relates to a kind of small-bore electric submersible screw pump speed reducer eccentric drive shaft.
Background technique
Existing small-bore electric submersible screw pump speed reducer mostly is few teeth difference and moves speed reducer, and speed reducer driving shaft installs eccentric bushing additional, is connected between eccentric bushing and transmission shaft by key, the integrity of transmission shaft is poor, and transmission shaft mechanical property can decline, and the power of transmission also reduces.
Summary of the invention
The utility model to provide a kind of novel small-bore electric submersible screw pump speed reducer eccentric drive shaft, solves the problem of small-bore electric submersible screw pump speed reducer driving shaft hydraulic performance decline.
The utility model solves the technological scheme that its technical problem adopts:
A kind of small-bore electric submersible screw pump speed reducer eccentric drive shaft, comprise transmission shaft body, its special way is: the middle part of described transmission shaft body is respectively equipped with the eccentric body be integrated with transmission shaft body from front to back, and two eccentric bodies misplace layout up and down.
The utility model replaces transmission shaft to replace the Split type structure of speed reducer driving shaft, eccentric bushing and key by the eccentric drive shaft of integrative-structure.Operationally, because eliminate eccentric bushing and key, eccentric drive shaft need not spline, and increase compared with in the of 7% with diameter of axle when offering a keyway, overall performance improves 10%, improves the power of transmission.
Accompanying drawing explanation
Fig. 1 is the transmission shaft structure schematic diagram of former small-bore electric submersible screw pump speed reducer;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is scheme of installation of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises speed reducer eccentric drive shaft body 1, and the middle part of described transmission shaft body 1 is respectively equipped with the eccentric body 2,3 be integrated with transmission shaft body 1 from front to back, and two eccentric bodies 2, about 3 misplace layout.
As shown in Figure 3, during installation, the transmission shaft body 1 of this small-bore electric submersible screw pump speed reducer eccentric drive shaft is connected with planetary pinion 4.
Claims (1)
