Embodiment
Further the present invention will be described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of novel axial piston motor, by output shaft 20, cylinder body 14, plunger 6, piston shoes 12, platen 11,
The parts such as swash plate 1, swash plate 2 28, valve plate 15, front end housing 22, central enclosure 29, back cylinder cover 8 and end cap 16 are constituted.
All it is by bolt 1, packing ring between front end housing 22 and central enclosure 29 and between back cylinder cover 8 and central enclosure 29
2nd, the bolt group connection that nut 3 is constituted；Between front end housing 22 and central enclosure 29 and between back cylinder cover 8 and central enclosure 29 all
Sealed using felt collar 1；Connected, adopted between back cylinder cover 8 and swash plate 1 using screw 2 17 between front end housing 22 and end cap 16
Connected, all sealed between front end housing 22 and end cap 16 between back cylinder cover 8 and swash plate 1 using felt collar 27 with screw 1.
As depicted in figs. 1 and 2, it is arranged in the left side plunger 6 of swash plate 1 on piston shoes 12, platen 11 is by plunger 6 and slides
Boots 12 are pressed on swash plate 1, while under the spring 25 of the end of output shaft 20, compression axis 26, the collective effect of steel ball 27,
Piston shoes 12 are tightly pressed against on swash plate 1.The plunger 6 on the right side of swash plate 2 28 is arranged on piston shoes 12, and platen 11 is by the He of plunger 6
Piston shoes 12 are pressed on swash plate 2 28, and the left side of swash plate 2 28 is fastened and connected with front end housing 22.Between swash plate 1 and swash plate 2 28
Have respectively between two cylinder bodies 14 and middle casing 29 and be provided with oil inlet Y1 and oil discharge outlet Y2 on valve plate 15, middle casing 29,
