Abstract
The utility model relates to an automatic reversing device of a novel cycloidal gear lubricating oil pump, and belongs to the field of machinery. The automatic reversing device is in an eccentric round bush structure and arranged between an oil pump seat and an outer rotor; the automatic reversing device comprises an eccentric round bush body and a semicircular groove; the semicircular groove is arranged at the outer edge of the eccentric round bush body; and the semicircular groove corresponds to a limiting pin arranged inside the oil pump seat and is limited by the limiting pin, so as to from two symmetrical eccentric positions, so that the reversing device rotates for 180 degrees. The automatic reversing device has the advantages that the automatic reversing device is simple in structure and convenient to use; the oil pump does not need to be dismantled; an oil-way board is not exchanged; an oil inlet way and an oil outlet way of the pump and a hydraulic fluid port are not changed, so as to achieve the purpose of automatically adjusting the turning direction of the oil pump; fixing of an oil discharge port is achieved; connection of an oil absorption cavity and the semicircular groove is avoided; the noise is reduced; processing deformation is reduced; the practicability is strong; and the technical problem of processing deformation in slotting because the size of a notch part at the end face is small is solved.
Description
Technical field
The utility model relates to mechanical field, and particularly a kind of New-type cycloidal gear lubricating oil pump automatic reversing apparatus is applied to the crankshaft lubrication mechanism of pendulum type compressor.
Background technique
Present employed oil pump is that the pump housing directly is processed into off-centre mostly, install once only to allow to a direction rotation, otherwise inhale during counter-rotating, oil-discharging cavity exchanges can't be to engine crankshaft bush place fuel feeding.During such as needs sense of rotation and factory setting opposite direction, then need to unload oil pump, backing pump 120 degree, is installing behind the change oil circuit the stifled position of transposing oil.The producer that also has changes oil-way board change direction with adding, and so also will change oil-way board with unloading oil pump, and operating wastes time and energy, very inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of New-type cycloidal gear lubricating oil pump automatic reversing apparatus, what solved the prior art existence can only unload the problem that oil pump could be changed sense of rotation, and solved at the grooved faces spot size littlely, the technical barrier of machining deformation has occured during fluting.The utility model main body is installed between oil pump seat and the external rotor, to have one-way pump now and change two-way pump into, a position limit pin is installed, the frictional force of outer rotor diameter and reversing cover internal diameter and fluid stickiness make reversing arrangement Rotate 180 degree, make off-centre change to the symmetrical position of former off-centre, reach the commutation purpose, when as long as oil pump seat and reversing cover gap are not excessive, external rotor total energy extruding reversing cover produces frictional force, because reversing cover has off-centre.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
New-type cycloidal gear lubricating oil pump automatic reversing apparatus, described automatic reversing apparatus is eccentric circle nested structure, be installed between oil pump seat and the external rotor, comprise eccentric circle cover main body 1 and semicircle circular groove 2, the outer rim of described eccentric circle cover main body 1 arranges semicircle circular groove 2, described semicircle circular groove 2 is corresponding and spacing by it with the position limit pin in being arranged on the oil pump seat, forms the eccentric position of two symmetries, makes reversing arrangement Rotate 180 degree.So layout semicircle circular groove has avoided oil sucting cavity and semicircle circular groove 2 to communicate, and noise is reduced, and reduced machining deformation.
The width of described semicircle circular groove 2 is 6mm, and the degree of depth is 4mm.
The beneficial effects of the utility model are: simple in structure, easy to use.Do not need to dismantle oil pump, need not change oil-way board, pump enter the oil extraction road and hydraulic fluid port constant, reach the purpose of automatic adjustment oil pump rotation direction, and make and unload the oil pressure mouth and fixedly become a reality.And avoided oil sucting cavity and semicircle circular groove to communicate, noise has been reduced, and reduced machining deformation, practical.

Embodiment
Further specify detailed content of the present utility model and embodiment thereof below in conjunction with accompanying drawing.
Extremely shown in Figure 4 referring to Fig. 1, New-type cycloidal gear lubricating oil pump automatic reversing apparatus of the present utility model, described automatic reversing apparatus is eccentric circle nested structure, be installed between oil pump seat and the external rotor, comprise eccentric circle cover main body 1 and semicircle circular groove 2, the outer rim of described eccentric circle cover main body 1 arranges semicircle circular groove 2, and described semicircle circular groove 2 is corresponding and spacing by it with the position limit pin in being arranged on the oil pump seat, form the eccentric position of two symmetries, make reversing arrangement Rotate 180 degree.So layout semicircle circular groove has avoided oil sucting cavity and semicircle circular groove 2 to communicate, and noise is reduced, and reduced machining deformation.
Referring to shown in Figure 5, when bent axle turns clockwise, internal rotor also turns clockwise and drives external rotor and also turn clockwise, and the frictional force of the outer footpath of external rotor and reversing cover internal diameter and fluid adhesive tape are moved to device and are turned clockwise, but because position limit pin blocks the limit position of reversing arrangement, make reversing arrangement motionless, thereby make eccentric position constant.Because frictional force drives the trend that reversing cover only turns clockwise, so oil can only from following suction, be discharged from the top oil pocket.
Referring to shown in Figure 6, when bent axle is rotated counterclockwise, internal rotor also is rotated counterclockwise, the drive external rotor is rotated counterclockwise, and the moving reversing cover of external rotor frictionally and oily adhesive tape also is rotated counterclockwise, position limit pin did not limit reversing cover and was rotated counterclockwise in half ring annular groove this moment, and the moving reversing cover of external rotor frictionally and oily adhesive tape is rotated counterclockwise, another limit position of half ring annular groove of reversing cover is contacted with position limit pin, thereby reversing cover is stopped the rotation, oil make reversing cover arrive another symmetrical eccentric position, so can only from following suction, be discharged from the top oil pocket.Thereby make oil sucting cavity, oil-discharging cavity constant, inlet port, oil drain out and oil circuit are constant, reach the commutation purpose.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
