Abstract
The utility model provides a high temperature gear hydraulic motor, which comprises a motor body, a bigger gear with a PTO (Power Take-Off) and a smaller gear meshed with the bigger gear, wherein an oil inlet for high pressure oil and an oil outlet for lower pressure oil are respectively formed on two sides of the meshed area between the bigger and the smaller gears. By adopting the meshed manner of the bigger gear and the smaller gear, the utility model takes the smaller gear as an assistant structure and the bigger gear as an output structure, thereby greatly reducing the size of the gear hydraulic motor under the same torque output, and being more applicable to the borehole operating environment.
Description
Technical field
The utility model relates to a kind of high temperature gear type motor.
Background technique
At present, in oil exploration, in the side-wall coring operation, use vane motor usually as power source.But because subsurface environment is extremely abominable, hydraulic oil is polluted through regular meeting, and vane motor is had relatively high expectations to hydraulic oil, so produce fault through regular meeting because of oily reason, what influence was produced normally carries out.When using gear type motor to carry out borehole wall operation, because pitch wheel has same standard pitch circle size in the conventional gears oil hydraulic motor, under situation about reaching with constant power, this kind gear type motor volume is bigger, and subsurface environment is a sleeve configuration, and this just causes the gear type motor can't normal operation.In addition, present oil hydraulic motor because the face leakage situation appears in thermal expansion, reduces the oil hydraulic motor working efficiency through regular meeting under hot environment, influence normal underground work.
The model utility content
The technical problems to be solved in the utility model provides a kind of power height, volume is little and resistant to elevated temperatures high temperature gear type motor.
In order to address the above problem, the utility model provides a kind of high temperature gear type motor, comprise motor body, have the gearwheel of power output and the small gear that meshes with described gearwheel, be respectively arranged with high pressure oil filler opening and low pressure oil oil outlet at described gearwheel and both sides, pinion district.
Further, be provided with between described gearwheel and small gear two ends end face and the described motor body and be used for carrying out under the hot environment first side plate and second side plate that the gap compensation is pressed mutually, described first side plate is near described gearwheel and small gear two ends end face, and described second side plate is near described motor body.
Further, described first side plate is a high-abrasive material, and described second side plate is the high thermal expansion coefficient material.
The utlity model has following advantage:
1, with the form of novel employing gearwheel and pinion, for auxiliary, gearwheel is an export structure with small gear, under equal moment output, greatly reduces the size of gear type motor, more can adapt to working environment at coal mines.
2, with novel employing first side plate and second side plate, under hot environment, carry out temperature compensation on the one hand, improve wear-resisting property on the one hand, make the utility model more can adapt to the operation under the hot environment.
Description of drawings
Below in conjunction with accompanying drawing mode of execution of the present utility model is described further:
Fig. 1 shows a kind of high temperature gear type motor of the utility model structural representation;
Fig. 2 shows a kind of high temperature gear type motor of the utility model sectional structure schematic representation;
Fig. 3 shows first side plate in a kind of high temperature gear type motor of the utility model, the second side plate structure for amplifying schematic representation.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises motor body 1, gearwheel 2 small gears 3.Motor body 1 is main body of the present utility model and support, forms chamber 10 in inside, and gearwheel 2 and small gear 3 all are arranged in this chamber 10.
Gearwheel 2 links to each other with the axle 13 of power output, is used for power output, and gearwheel 2 is fixedly installed on this pto 13 by flat key 14.Small gear 3 and gearwheel 2 engagements, it is right to constitute swing pinion with gearwheel 2.
Also be provided with high pressure oil filler opening 11 and low pressure oil oil outlet 12 on the motor body 1.Be arranged on the both sides of gearwheel 2 and small gear 3 meshing zones respectively symmetrically at high pressure oil filler opening 11 and low pressure oil oil outlet 12.
In the utility model working procedure, from these high pressure oil filler opening 11 input high pressure oils, high pressure oil promotes intermeshing gearwheel 2 and rotates with small gear 3, thereby drives pto 13 rotations, carries out power output by oil pipe.High pressure oil pressure in promoting gearwheel 2 and small gear 3 rotating process reduces, and finally becomes low pressure oil, discharges motor bodies from low pressure oil oil outlet 12, and returns by oil pipe, forms circulation.
The form that the utility model adopts gearwheel 2 and small gear 3 to mesh, for auxiliary, gearwheel 2 is an export structure with small gear 3, under equal moment output, greatly reduces the size of gear type motor, more can adapt to working environment at coal mines.
As Fig. 2, shown in Figure 3, in the utility model, be provided with first side plate 4 and second side plate 5 between gearwheel 2 and small gear 3 two ends end faces and the motor body 1.First side plate 4 and second side plate 5 are used under the hot environment temperature compensation being carried out in gap between gearwheel 2 and small gear 3 two ends end faces and the motor body 1.
In the utility model, first side plate 4 is a high-abrasive material, and second side plate 5 is the high thermal expansion coefficient material.Under hot environment, gap enlargement between gearwheel 2 and small gear 3 and the motor body 1, second side plate 5 is the high thermal expansion coefficient material, under hot environment, expansion is many, thereby compensates the gap of this expansion.First side plate 4 is a high-abrasive material, can reduce gearwheel 2 and the wearing and tearing of small gear 3 in rotation process, thereby prolongs the life-span of gearwheel 2 and small gear 3.
The utility model adopts first side plate 4 and second side plate 5, under hot environment, carries out the gap temperature compensation on the one hand, improves gearwheel 2 and small gear 3 wear-resisting propertys on the one hand, makes the utility model more can adapt to the operation under the hot environment.
In the utility model, the high-abrasive material in first side plate 4 is a refractory steel, and the high thermal expansion coefficient material in second side plate 5 is a copper.
In sum; it below only is preferred embodiment of the present utility model; be not to be used to limit protection domain of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
