Abstract
The utility model discloses a guiding slip ring type sloping cam plate limiting mechanism used in a sloping cam plate connecting rod type axial piston pump, to lead the sloping cam plate to perform spherical swing. The limiting mechanism comprises a guiding slip ring (6), a pair of first pin shafts (4) and a second pin shaft (1); the guiding slip ring (6) is fixed on the pump housing in a rotating manner through the pair of the first pin shafts (4); at the same time the sloping cam plate is fixed on the guiding slip ring (6) in a rotating manner through the second pin shaft (1); the axes of the pair of the first pin shafts (4) are in the same straight line and pass the center of the sloping cam plate; and the axis of the second pin shaft (1) is perpendicular to the axes of the first pin shafts (4) and also passes the center of the sloping cam plate. The sloping cam plate limiting mechanism is applicable to the sloping cam plate connecting rod type axial piston pumps adopting sea-water, fresh water, high water base, mineral oil, and the like as actuating medium, and has the advantages of simple technology, reliable operation, long service life and low vibration noise.
Description
Technical field
The utility model belongs to the parts of swash plate linkage type axial piston pump, is specifically related to a kind of guide link formula swash plate position-limit mechanism, is applicable to swash plate linkage type water pressure plunger pump and oil pressure plunger pump.
Background technique
The swash plate position-limit mechanism is the critical component in the swash plate linkage type axial piston pump.Swash plate linkage type axial piston pump relies on the swash plate position-limit mechanism to limit the rotation of swash plate around axis just, and force it can only do to swing around the sphere at its center, thereby form the swash plate linkage mechanism in space, the hinged drive plunger by swash plate and plunger connecting rod assembly does reciprocating linear motion in the cylinder hole.Traditional swash plate linkage type axial piston pump adopts slide block type swash plate limit structure, as shown in Figure 2, guide runner 9 is installed in the pin-and-hole of swash plate 7, guide runner 9 can freely rotate with respect to swash plate 7, guide chute 8 is fixed on the pump case 3, guide runner 9 is done reciprocally circular arc slip in guide chute 8, thereby the restriction swash plate is around the rotation of axis.Because the face contact belongs to sliding friction between guide runner and the guide chute, produces mechanical noise clearly, and guide runner is subjected to very big lateral force, and surface of contact PV value is excessive, and it is very fast to wear and tear, and excessive wear appears in a stressed side very soon.Because sliding friction pair can't satisfy the requirement of PV value by changing pairing material or increasing area of contact, replace sliding friction with rolling friction, guide runner after the improvement as shown in Figure 3, bearing pin 11 is installed in the pin-and-hole of swash plate, rolling element 12 is installed on the bearing pin by needle bearing 13, rolling element is done reciprocally in guide chute, and circular arc rolls, rolling limit structural life-time is apparently higher than the slide block type limit structure, but because there are the gap in rolling element and guide chute inwall, rolling element is in guide chute during high speed scroll, mechanical impact constantly takes place, produce noise, shock and vibration, cause the loosening gradually so that destruction of needle bearing, may cause connecting rod to fracture when serious, finally cause plunger pump not work.
Summary of the invention
The utility model provides a kind of guide link formula swash plate position-limit mechanism, the space of being intended to the arc swing of guide runner in guide chute is converted into guide link rotatablely moves, avoid the vibration and the noise that produce owing to the direct collision between the mechanical part, improve the working life of swash plate position-limit mechanism.
Realize that the technological scheme that the utility model adopted is:
A kind of guide link formula swash plate position-limit mechanism, be used for swash plate linkage type axial piston pump, so that swash plate is done the sphere swing, it is characterized in that, this position-limit mechanism comprises guide link, a pair of first bearing pin and one second bearing pin, described guide link is rotatably mounted on the pump case by this a pair of first bearing pin, described swash plate is rotatably mounted on the described guide link by described second bearing pin simultaneously, the axis of described a pair of first bearing pin is located along the same line and by the swash plate center, the axis normal of the axis of described second bearing pin and first bearing pin and pass through the swash plate center.
As further improvement of the utility model, described guide link is connected by rolling bearing with the first bearing pin guide link.
As further improvement of the utility model, described swash plate is connected with guide link by needle bearing.
The utility model be applicable to seawater, fresh water, high water base, mineral wet goods as in the swash plate linkage type axial piston pump of working medium as the swash plate position-limit mechanism, technology is simple, reliable operation, long service life, vibration noise are little.

Fig. 1 is a kind of example structure schematic representation of the present utility model;
Fig. 2 is traditional slide block type swash plate position-limit mechanism schematic representation;
Fig. 3 is traditional rolling type swash plate position-limit mechanism guide runner structural representation;
Be designated among the above-mentioned figure: second bearing pin 1, needle bearing 2, pump case 3, first bearing pin 4, rolling bearing 5, guide link 6, swash plate 7, guide chute 8, guide runner 9, cylinder body 10, bearing pin 11, rolling element 12, needle bearing 13, hubcap 14.
Embodiment
Fig. 1 is a kind of embodiment of the present utility model, this guide link formula swash plate position-limit mechanism comprises guide link 6, first bearing pin 4 and second bearing pin 1, and the rotation that limits swash plate by guide link 6 forces it to do that the sphere swing is finished suction with the keying that promotes plunger and cooperate flow-distributing valve and draining is moved.Described guide link 6 is spacing by a pair of first bearing pin 4 that is installed on the pump case 3, and first bearing pin 4 links to each other with guide link 6 by rolling bearing 5, and the restricted guidance slip ring can only be made the space one dimension around the axis of first bearing pin 4 and rotate.
Second bearing pin 1 is fixed on the swash plate 7, this second bearing pin 1 links to each other with guide link 6 by needle bearing 2, swash plate can form the sphere swing in space around the rotational of second bearing pin 1 when being limited to rotate, second bearing pin 1 adopts interference fit with the inner ring of needle bearing 2.Monolateral radial clearance between guide link 6 and pump case 3, guide link 6 and the swash plate 7 is 3mm, and the axis of a pair of first bearing pin 4 is located along the same line and mistake swash plate center, the axis normal of the axis of second bearing pin 1 and first bearing pin 4 and mistake swash plate center; Around the rotational of first bearing pin 4, while swash plate 7 is with respect to the rotational of guide link around second bearing pin 1 under the ordering about of swash plate 7 for guide link 6, thereby the sphere that forms the space is swung.
The utility model is when input speed and torque make main shaft do rotation motion, the swash plate 7 that is installed in main shaft crank throw place can only be around the rotational of second bearing pin 1 under the constraint of second bearing pin 1, simultaneously guide link 6 under the active force of swash plate 7 around the rotational of first bearing pin 4, thereby form the sphere swing of swash plate 7, promote plunger to-and-fro motion in the cylinder hole by connecting rod, cooperate the keying of flow-distributing valve to finish suction and draining action.
