Abstract
The invention discloses a non-beam long-stroke mechanical reversing pumping unit used for oil exploitation in an oil field. A reversing mechanism of a long-stroke mechanical reversing speed reducer comprises automobile differentials, brakes and the like; two groups of differentials are combined together; and during the reversing process, through revolution, autorotation and rotation based on speed and direction of bevel gears of the differentials, the reversing process is organically and skillfully finished. The stroke of the pumping unit can be up to 8 m, or even longer. All that is needed is to move a proximity switch, the stroke can be adjusted very conveniently. The problems that a chain of a chain-type pumping unit is easy to wear and a motor reversing pumping unit is started frequently are avoided. The pumping unit is reliable to operate, convenient to maintain, low in cost, and good in energy-saving effect. The pumping unit is used not only for onshore oil exploitation in the oil field but also for offshore oil exploitation in the oil field, and is also suitable for low-permeability oil wells.
Description
Technical field: the communtation deceleration mechanism that the present invention relates to a kind of ' reversing speed reducer ', especially used for oil-field oil pumper.
Background technique: existing changement have the commutation of motor commutation, chain, etc. form.The defective that these several changements exist is: (1) adopts the motor commutation mode, and essential ' frequency variator ' or ' switch magnetic group ' control motor commutation that adopts needs the frequent starting motor, and inrush current is very much not energy-conservation.Frequency variator produces many negative effects at work.(2) adopt the chain reversing mode, the transmission chain length, creep takes place in poor lubrication behind the chain wear, produce reversing impact, maintenance difficult, the maintenance expenses height, stroke can not be adjusted.
Goal of the invention: the purpose of this invention is to provide a kind of maintenance rational in infrastructure, reliable, good, cost low, energy-conservation obviously, regulate stroke mechanical commutation reducing gear easily.It thoroughly breaks away from the design philosophy with chain and the commutation of motor frequency conversion device, fundamentally solves problems such as frequent starting motor and chain wear creep.
Summary of the invention: for achieving the above object, communtation deceleration of the present invention mechanism has adopted two groups of automobile differentials and one group of planetary gear speed reducing mechanism.Planetary gear speed reducing mechanism is positioned at the centre of two groups of differential mechanisms.Planetary gear speed reducing mechanism is as driving wheel, and its input shaft directly connects with motor shaft, and its output gear drives two groups of differential mechanisms simultaneously and rotates in the same way.
Planetary gear speed reducing mechanism is made up of central gear, planet wheel, gear ring.Gear ring inside and outside all has tooth, internal tooth and planet wheel engagement, and the external gear of external tooth and differential mechanism meshes.Planetary gear speed reducing mechanism has a variety of structural types, and wherein NGW, 2K-H, 3K structural type all can satisfy usage requirement.
Differential mechanism is made up of two sun gears, four planetary pinions, cross axle and housing.Differential mechanism has many types, as spur-gear differential, cone gear differential mechanism, limited slip differential etc.Because simple and compact for structure, the stable working of cone gear differential mechanism is most widely used, and should preferentially adopt cone gear differential mechanism.
In the sun gear (inserting the gear of semiaxis) of two groups of differential mechanisms, insert four semiaxis respectively, export the front end of two semiaxis of a side and make bevel pinion, these two bevel pinions mesh with the bevel gear wheel that matches respectively, and bevel gear wheel is fixed on the output shaft, and is coaxial with output roller; Two semiaxis of an other side stretch out outside the casing, at this semiaxis hydraulic brake are housed, and it is the mechanism of control commutation.As long as alternately check this two breaks, differential mechanism is with regard to alternation.The planet wheel of differential mechanism and sun gear generation rotation, revolution, change speed, change direction are changeed organic commutation process of finishing dexterously.Realize the positive and negative rotation of output roller.
Beneficial effect: after the present invention adopted mechanical commutation, the largest benefit of acquisition was:
(1), motor is all the time to a direction uniform rotation, and uniform motion is best motion state.It does not need the commutation of motor frequent starting, has solved very much not problem of energy saving of inrush current, many negative effects of having avoided frequency variator to produce in frequency conversion, transformation process simultaneously.It is compared with chain drive pumping unit and has shortened Transmitted chains, has improved lubricating condition, has solved problems such as chain wear creep.
(2), driving wheel adopts Gear Planet Transmission to shorten Transmitted chains, has improved transmission efficiency, makes cabinet size compacter.
(3), the reversing speed reducer of being made up of two groups of differential mechanisms adopts semiaxis transmission, hydraulic braking and has delay function, and these all reduce reversing impact to greatest extent, make the stable working of reversing speed reducer reliable.
(4) differential mechanism in the reversing speed reducer, break, helical bevel gear, semiaxis etc. can adopt car gage spare, and quality is good, and price is low.
(5), complete machine of the present invention is in light weight, and is easy to maintenance, and few fault is convenient to install and transportation.
Description of drawings: Fig. 1 is the structural representation of reversing speed reducer.
Below in conjunction with width of cloth figure and embodiment the present invention is further described.
Embodiment: reversing speed reducer structural drawing shown in Figure 1 is a symplex structure, and motor output shaft passes to the central shaft of planetary gear speed reducing mechanism to moment of torsion, and differential mechanism 15,15 ' rotates under gear 19 drives in the same way.Differential mechanism 15,15 ' inserts semiaxis 16,16 ', and semiaxis 16,16 ' front end are bevel pinion, and the bevel gear wheel 17 of bevel pinion and pairing, 17 ' meshes, bevel gear 17,17 ' coaxial with cylinder 2; Two semiaxis 18,18 ' below the differential mechanism 15,15 ' stretch out outside the casing, and break 10,10 ' is installed.
The present invention is not limited to the above-described embodiment and examples field, no matter structurally do any variation, or uses this technology at other field.Every two groups of automobile differentials are combined, and alternately checked two breaks and change the mechanism that output shaft turns to, all drop within protection scope of the present invention.
