Description
Technical Field
The utility model belongs to the technical field of the gear box, concretely relates to external shaft coupling hydraulic oil pump unit.
Background
On agricultural machinery equipment or device, through adopting tractor input power, through power transmission to the gear box, after actual tractor and agricultural machine butt joint installation, still can involve some hydraulic control structures, often use the oil pump, through some hydraulic means of oil pump drive, some tractors do not have the structure of drive oil pump, need improve and install additional to the tractor structure in the use, still lead to the butt joint installation after the improvement troublesome, compatibility is poor between the mechanical structure of different grade type, the butt joint still needs some changeover parts, so use more complicacy.
Disclosure of Invention
An object of the utility model is to design an external shaft coupling hydraulic oil pump device, directly from agricultural machine's the external oil pump of gear, the power of oil pump comes from the gear box, does not need other power to provide the oil pump operation, also reduces the combination degree of difficulty and complexity.
In order to realize the purpose, the utility model adopts the technical scheme as follows:
the external coupling hydraulic oil pump device comprises a gear box, wherein a through hole is formed in one side of the gear box, an oil pump support is arranged in the through hole, a gland and a bearing seat are arranged on the inner side of the oil pump support, a coupling is arranged in the oil pump support, an oil pump is connected with a connected gear through the coupling, and the connected gear is meshed with a gear in the gear box.
Through above-mentioned technical scheme, the power of drive oil pump operation derives from the gear box, and the installation of structure comparison scheme is with dismantling, hydraulic means with have power oil pump connection, do not need other power supplies, also need not improve tractor, use the flexibility high, the oil pump adopts conventional agricultural machine to use the type, the cooperation precision is high, the fault rate is low, shaft coupling and disjunctor gear cooperation, transmission power is stable.
Furthermore, the oil pump support, the gland and the bearing seat are in butt joint through bolts and are stably connected.
Furthermore, the conjoined gear is arranged in the bearing seat, and a shaft of the conjoined gear is in butt joint with the coupler.
Furthermore, a sealing ring is arranged on the inner side of the gland to play a role in sealing.
Further, the gear is a plate wheel arranged on a gear box shaft.
The technical scheme can obtain the following beneficial effects:
the utility model discloses improve current gear box, only need open the through-hole, installed oil pump bracket, gland and bearing frame, with disjunctor gear, shaft coupling and oil pump put into the combination can, improve with low costs, the installation with dismantle the convenience.
The power source comes from the gear box, under disjunctor gear, shaft coupling cooperation, transmission power is stable, and hydraulic pressure is effectual. The matching degree between each part and each component is high, and the matching accuracy is high.
The tractor does not need to be provided with a hydraulic drive source, and the power is directly generated from the gear box to drive the oil pump to operate, so that the tractor is convenient to use and is more creative.
