Close to the edge of the swash plate, the end of the plunger of the piston shoes and plunger pump is slidably connected, also solid in the plane of the swash plate
Equipped with return plate, the end face of the return plate and the plane of the swash plate are affixed, and other end offers and the plunger pump
The groove that steel ball on pump shaft is slidably connected, the groove are located at the center of the swash plate, and the inside of the swash plate offers
Partially hollow, the partially hollow side being biased to where the plunger is fixed with a fixed block in the plunger pump, described solid
Determine that block is opposite with the spherical surface of the swash plate, the fixed block offers the negative camber being slidably connected with the spherical surface of the swash plate.
Wherein, it is described it is partially hollow be hollow cylinder, which is located at a side of the groove.
Wherein, axis pin is connected on the swash plate, the outer end of the axis pin is connected with rotary head, is fixedly installed in plunger pump
Locating piece, the rotary head are rotatablely connected with the locating piece.
Wherein, the locating piece offers socket, and the rotary head is turned by being inserted into the socket with the locating piece
Dynamic connection.
Wherein, the rotary head is set as hemisphere, and the hemispheroidal spherical surface and the axis pin are affixed, the socket side of being set as
Shape.
Wherein, the locating piece is located at the lower section of the fixed block.
Wherein, the medium position of the fixed block and the swash plate spherical surface is slidably connected.
Beneficial effects of the present invention：
Due to swash plate opened up it is partially hollow, so as to mitigate the weight of swash plate；And where the partially hollow deviation thrust plate
Side can make the intensity of swash plate stress bigger one end more preferable, to improve the intensity of swash plate in this way；In addition, fixed block has one
A negative camber that can be slidably connected with the spherical surface of swash plate, the fixed block are directly affixed with swash plate, woth no need to setting outward again
One is used for alignment pin position, and then reduces the internal structure of plunger pump, keeps the structure of plunger pump more compact.
