Abstract
The utility model discloses a special gear box for an offshore petroleum machine. The special gear box comprises a gear box body (1) and a motor. A through hole (7) is arranged in an input port (6), and an output port (2) of the gear box body (1) corresponds to an inlet of the motor; a driving gear and a driven gear are further rotatably disposed in a cavity of the gear box body (1); the driving gear is mounted on an output shaft of the motor and positioned in the gear box body (1); the driven gear is mounted in the gear box body (1) by a gear shaft; and an inner cavity of the output port (2) of the gear box body is divided into a first cavity (5) and a second cavity (3) by the position where the driving gear and the driven gear are meshed with each other, and a groove (4) is axially arranged in the first cavity (5) along the gear shaft and is communicated with the first cavity (5) and the second cavity (3). The internal structure of the gear box is improved, so that liquid circulation in the gear box can be kept all along, residual heat in equipment can be effectively dissipated, and normal running of the equipment is guaranteed.
Description
Technical field
The utility model relates to a kind of casing of gear-box, is specifically related to a kind of offshore oil machinery dedicated gear casing.
Background technique
Existing gear housing in the offshore oil pipe-line system does not generally arrange cooling mechanism, and fricative heat mainly outwards conducts by tank wall during gear operation.This existing gear housing is used for the cold area ocean, and the heat that equipment produces in running can rely on marine stream to take away, and therefore basically can satisfy the normal heat radiation requirement of gear housing.
But in the time of will having gear housing now and be applied to Tropical Ocean Area, because ocean temperature is higher, the heat in the gear housing is difficult in time distribute, and causes the box house excess Temperature, and then its service behaviour and shorten its working life.Therefore the heat radiation of torrid areas submarine oil pipe-line system middle gear casing is the technical barrier that one of ordinary skill in the art need to be resolved hurrily always.
The model utility content
Technical problem to be solved in the utility model is, a kind of offshore oil machinery dedicated gear casing is provided, and can effectively the waste heat in the equipment be taken away by liquid, to overcome the defective of existing gear housing.
It is as follows that the utility model solves the problems of the technologies described above the technological scheme that adopts:
Offshore oil machinery dedicated gear casing, it is characterized in that: comprise that two ends are with the gear housing of inlet opening and delivery outlet, be provided with through hole in the described inlet opening, also comprise motor, the output shaft of motor penetrates through described through hole from the inlet opening of gear-box and extends in the cavity of gear housing; The delivery outlet of described gear housing is corresponding with the position of motor import; Also be provided with rotationally driving gear and driven gear in the gear-box body cavity; Driving gear is installed on the motor output shaft and is positioned at gear housing; Driven gear is installed in the gear housing by gear shaft; Driving gear and driven gear engagement place are divided into the first chamber and the second chamber with gear housing delivery outlet inner chamber, axially are provided with groove along gear shaft in the first chamber, and groove communicates with the first chamber and the second chamber.
Good effect of the present utility model is:
The utility model has improved the internal structure of gear housing, can remain liquid-circulating in gear housing, effectively takes away the waste heat in the equipment, has guaranteed that equipment normally moves, and has improved service life of equipment.Can satisfy well in the offshore oil machinery of torrid areas and use.
Gear rotational speed adjustable range of the present utility model is large, so its fluid flow range that can provide is large, can reach 5～300 liter/mins of clocks.The noise of its generation only is that noise is little below 10 decibels.

Embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Shown in Fig. 1,2,5, the utility model comprises that two ends are with the gear housing 1 of inlet opening 6 and delivery outlet 2, be provided with through hole 7 in the described inlet opening 6, also comprise motor, the output shaft of motor penetrates through described through hole 7 from the inlet opening 6 of gear-box 1 and extends in the cavity of gear housing 1.
The delivery outlet 2 of described gear housing 1 is corresponding with the position of motor import.Like this, the liquid from 2 outputs of gear housing 1 delivery outlet can enter in the motor casing through the motor import, is transported to specified position through motor casing outlet, transport pipe again.
Also be provided with rotationally driving gear and driven gear in the gear housing l chamber.Driving gear is installed on the motor output shaft and is positioned at gear housing 1; Driven gear is installed in the gear housing l by gear shaft.
Such as Fig. 3,4, gear housing delivery outlet 2 inner chambers are divided into the first chamber 5 for driving gear and driven gear engagement place and 3, the first chambeies 5, the second chamber are interior axially is provided with groove 4 along gear shaft, and groove 4 communicates with the first chamber 5 and the second chamber 3.
In the present embodiment, gear shaft is positioned at gear housing 1 fully.The mutual outer gearing of driving gear and driven gear, driving gear is identical with the driven gear size.The tooth of driving gear 3 along the circumferential direction isoperimetric is arranged.The tooth of driven gear 4 along the circumferential direction isoperimetric is arranged.
Driving gear and driven gear are involute gear.
Working principle of the present utility model is: liquid enters groove 4 through delivery outlet 2, then enters in the first chamber 5.Motor output shaft drives the driving gear rotation, and then drives the driven gear rotation.In driving gear and the driven gear rotary course, bring in the second chamber 5 after the gear rotation at the liquid between two wheel teeth.Two gear outer gearings, in the rotary course, spatial volume that can receiving fluids in the second chamber 5 can and change along with two gears rotations, and liquid is produced pressure, and compressing liquid flow to delivery outlet 2, then outputs to specified position through transport pipe again through the motor casing inner chamber.
