Description
Technical field:
The utility model relates to the fluid pump technical field, refers in particular to a kind of constant current to the cycloid rotor lubricant pump.
Background technique:
Be to guarantee effective lubricating or in cutting, make workpiece obtain lubricated fully and cooling on lathe or the electromechanical equipment, often need a cover lubrication oil supply device, lubricant pump is the heart of lubricating fitting, and therefore correct selection lubricant pump is that the design and craft personnel must consider.
The structural type of lubricant pump and lubricating system are diversified, for example plunger type, blade type, gear type or the like are arranged, but the flow direction of these its fluid of pump all is subjected to the restriction of main axis rotation direction, promptly turning to of pump is irreversible, with general cycloid rotor pump, also be like this.If main shaft turn to change, then inhale, press the direction of oil to change thereupon.The driving of lubricant pump is not by the motor single driving on some lathe, drives lubricant pump but be connected with the transmission shaft of lathe.According to the operating mode needs, turning to of transmission shaft needs just to change sometimes, then needs counter-rotating sometimes, under these circumstances, general lubricant pump just can not keep constant current to continuous oil supply, can not satisfy the needs of lubrication system.
Summary of the invention:
But the purpose of this utility model provide a kind of when rotor shaft is done clockwise or is rotated counterclockwise all constant current to the cycloid rotor lubricant pump of oil extraction.
The utility model is achieved in that constant current is to the cycloid rotor lubricant pump, include the pump housing and eccentric bushing, it is characterized in that on the outer wall of eccentric bushing, offering semicircular chute, locating stud is fixed on the pump housing and can slides in the semicircle chute of eccentric bushing, position in the hollow of eccentric bushing is disposed with intermeshing inner cycloidal gear of a pair of negative and positive gear and epicycloidal gear from inside to outside, inner cycloidal gear is rotated by drive shaft, epicycloidal gear under the drive of inner cycloidal gear with inner cycloidal gear and the equidirectional rotation of eccentric interplanting, eccentric bushing is subjected to maintain static after the restriction of locating stud, be provided with the oil extraction district on the top of epicycloidal gear, be provided with the oil suction district in the bottom of epicycloidal gear, when inner cycloidal gear commutates, eccentric bushing is also done to be subjected to the restriction of locating stud after equidirectional rotation 180 is spent under epicycloidal gear drives and is maintained static, thereby realizes above-mentioned oil extraction district, the oil suction district does not change.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model utilizes an eccentric bushing that can carry out 180 degree rotation change eccentric directions to realize that suction, oil extraction district do not change with turning to change, but thereby realize rotor shaft drive cycloidal gear when doing clockwise or being rotated counterclockwise all constant current to oil extraction, guaranteed lubricant pump constant current continuously to ground the lubricant oil to the position supply certain pressure that equipment need lubricate.
2, the utility model is simple in structure, stable work in work, and low production cost suits to apply in lubricated equipment of various needs or system.
Description of drawings:
Fig. 1 is the structure working principle figure when spindle axis counterclockwise Rotate 180 degree to locating stud blocks locating point of eccentric bushing of the present utility model;
Fig. 2 is the structure working principle figure when main shaft dextrorotation turnback to locating stud blocks another locating point of eccentric bushing of the present utility model.
The direction of arrow among Fig. 1-2 is the sense of rotation that main shaft drives inner cycloidal gear.
Embodiment:
With specific embodiment the utility model is further described below:
Referring to Fig. 1-2: constant current is to the cycloid rotor lubricant pump, include the pump housing 10 and eccentric bushing 20, it is characterized in that on the outer wall of eccentric bushing 20, offering the semicircle chute 201 of 180 degree, locating stud 50 is fixed on the pump housing 10 and can slides in the semicircle chute 201 of eccentric bushing 20, position in the hollow of eccentric bushing 20 is disposed with intermeshing inner cycloidal gear 40 of a pair of negative and positive gear and epicycloidal gear 30 from inside to outside, inner cycloidal gear 40 is rotated by drive shaft, epicycloidal gear 30 is done equidirectional rotation with inner cycloidal gear 40 under the drive of inner cycloidal gear 40, meanwhile eccentric bushing 20 is also done maintained static by the restriction of locating stud after the equidirectional rotation, be provided with oil extraction district 60 on the top of epicycloidal gear 30, be provided with oil suction district 70 in the bottom of epicycloidal gear 30, when inner cycloidal gear 40 commutations, eccentric bushing 20 is also done to be subjected to the restriction of locating stud 50 after equidirectional rotation 180 is spent under epicycloidal gear 30 drives and is maintained static, thereby realizes above-mentioned oil extraction district 60, oil suction district 70 does not change.
Working principle of the present utility model: the utility model is made up of a pair of cycloidal gear, inner cycloidal gear 40 rotates under the drive of live axle, epicycloidal gear 30 is done equidirectional rotation with epicycloidal gear 30 under the drive of inner cycloidal gear 40, because inside and outside cycloidal gear 30 differs a tooth, therefore has certain space (volume), so this pump can play constant current to effect, i.e. turning to of the flow direction of oil extraction and live axle is irrelevant, and its key is the effect of eccentric bushing.Referring to Fig. 2: when inner cycloidal gear 40 (driving wheel) clockwise direction rotates, eccentric bushing 20 is also made clockwise direction and is rotated under the drive of epicycloidal gear 30 (follower), but be subjected to the restriction of locating stud 50 and be fixed on the position, owing to changing from small to big, volume forms oil suction district 70 this moment in illustrated left bottom, and upper left volume diminishes gradually and forms oil extraction district 60, and oil suction district 70 and oil extraction district 60 are isolated mutually by the gear teeth of conjugation; Referring to Fig. 1: when inner cycloidal gear 40 (driving wheel) counterclockwise rotates, eccentric bushing 20 counter-rotatings simultaneously, rely on the effect of locating stud 50 and just in time differ 180 ° with Fig. 2, the district of oil suction at this moment 70 has forwarded the lower right to, the oil extraction district is then in the upper right, but the relation in oil suction district 70 and oil extraction district 60 does not change, it can realize that the below is the oil suction district by distributing groove, the top is the oil extraction district, the oil suction district communicates with the oil sump of equipment, the oil extraction district communicates with the lubricating oil path of equipment, thus guaranteed lubricant pump constant current continuously to ground the lubricant oil to the position supply certain pressure that equipment need lubricate.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
