Description
technical field:
The utility model relates to oil hydraulic pump technical field, specifically a kind of special gradient dish of axial piston pump removed for railway hydraulic.
background technique:
Axial piston pump utilizes the volume-variation that produces of plunger plunger hole in the to-and-fro motion parallel with transmission shaft to carry out work; Because plunger and plunger hole are all circular pieces, add the class fit that can reach very high man-hour, therefore there is volumetric efficiency high, smooth running, discharge uniformity is good, and noise is low, working pressure advantages of higher, is widely used in the fields such as lathe, metallurgy, mining machinery, engineering machinery, boats and ships; At present, in patent CN202746172U disclosed in Chinese patent literature, disclose a kind of novel axial plunger pump, this novel axial plunger pump comprises the front pump housing, middle pump body, cylinder body, outer cylinder body, bonnet and transmission shaft, the front pump housing is by bearing fit in transmission shaft one end, and cylinder body is sleeved on the transmission shaft the other end, outer cylinder body and cylinder body excircle interference fit, middle pump body is coordinated with outer cylinder body excircle by needle bearing, after be covered on end part of driving shaft and be fixedly connected with middle pump body one end; The middle pump body the other end is fixedly connected with front pump housing one end, cylinder body end face is shaped with plunger hole, piston bore bottom is provided with piston spring, piston spring one end is connected with piston bore bottom, the piston spring the other end is connected with plunger at one end, cylinder ends is provided with disc and disc one end and the plunger the other end push against, and the disc the other end matches with the swash plate being fixed on rear cover cavity; Although make plunger return at plunger base design piston spring, original slip is become rolling massage, but when being used for the work condition environment that railway hydraulic is removed, because load is comparatively large and when affecting piston spring with drive axis by rail vibration, spring is easy to twist off, and by end face bearing touch between disc and swash plate, the sliding friction of minimizing is also little; Each parts of the axial piston pump removed for railway hydraulic are extremely important.
summary of the invention:
The purpose of this utility model is to provide a kind of special gradient dish of axial piston pump removed for railway hydraulic.
The utility model adopts following technological scheme to realize its goal of the invention: a kind of special gradient dish of axial piston pump removed for railway hydraulic, it makes swash plate 1 by steel, and on swash plate 1, be provided with wobbler shaft 2, swash plate pin-and-hole 3, thrust plate limiting block ring recess 4; Wobbler shaft 2 is central shafts of swash plate 1; It is inner that swash plate pin-and-hole 3 is located at swash plate 1; Thrust plate limiting block ring recess 4 is located at wobbler shaft 2 front end; Inclination angle A is swashplate angle, limits by radial force, and inclination angle A is no more than 20
0; Produce to-and-fro motion by promoting plunger with the swash plate 1 of inclination angle A, change cylinder body plunger cavity internal volume carries out sucking and eject the oil suction oil extraction function realizing pump.
Owing to have employed above technological scheme, the utility model achieves its goal of the invention preferably, the special gradient dish of axial piston pump removed of this railway hydraulic produces to-and-fro motion by promoting plunger with the swash plate of inclination angle A, change cylinder body plunger cavity internal volume carries out sucking and discharge the oil suction oil extraction function that just can realize pump, structure is simple to operation and working efficiency is high, is the vitals of axial piston pump.
accompanying drawing illustrates:
Accompanying drawing 1 is overall structure schematic diagram of the present utility model.
