In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide the cam-type axial piston pump of a kind of distributing cup-shaped cylinder body and roller bearings, the vibration of cylinder body can be reduced, avoiding frictional force between swash plate and piston shoes.
In order to achieve the above object, the present invention takes following technological scheme:
The cam-type axial piston pump of a kind of distributing cup-shaped cylinder body and roller bearings, comprise a live axle 18, live axle about 18 two ends are arranged on left end cap 3 and right end cap 14 respectively by clutch shaft bearing 2 and the second bearing 16, left end cap 3, right end cap 14 and shell 5 are fixed together, at left end cap 3, the outside of right end cap 14 is separately installed with the first end cover 1 and the second end cover 17, be connected with swash plate 12 on the right side of the middle part of live axle 18, the left side of swash plate 12 is connected with several plunger 10 by ball pivot, the right side of swash plate 12 is arranged on rolling bearing 13, rolling bearing 13 is fixed on to be determined on swash plate 15, determining swash plate 15 is fixed on right end cap 14, be connected with lubricating cup mounting plate 6 on the left of the middle part of live axle 18, be connected with flow assembly 4 on the left of lubricating cup mounting plate 6, by link 19, several lubricating cup 8 is installed on the right side of lubricating cup mounting plate 6, lubricating cup 8 is connected with the sliding end of plunger 10, swash plate 12 contacts with swash plate support block 11, lubricating cup mounting plate 6 contacts with lubricating cup pressure strip 7, and the two ends of spring 9 are connected on lubricating cup pressure strip 7 and swash plate support block 11, makes swash plate 12 and determines swash plate 15 keeping parallelism.
Described live axle 18 is connected by the spline of arc-shaped and swash plate 12, and live axle 18 is connected with lubricating cup mounting plate 6 by spline.
Beneficial effect of the present invention is: live axle 18 can realize swash plate 12 in live axle rotary course and lubricating cup mounting plate 6 cophasing rotates, and decreases the friction between plunger 10 and cylinder body; Lubricating cup 8 and plunger 10 are formed can the cavity volume of mechanical periodicity, eliminates original plunger pump cylinder body, decreases the quality of revolving part, reduce rotary inertia; Swash plate 12 is pressed on rolling bearing 13 by spring 9 and swash plate support block 11, and the form adopting the form of rolling bearing can cancel common cam-type axial piston pump piston shoes to rub on swash plate, improves the reliability of pump.
