具体实施方式Detailed ways
如图1和图2所示，本发明所述的液压泵配油盘的防抖动固定结构，主要包括有液压泵配油盘1、2个第一固定螺钉2和2个第二固定螺钉3。As shown in FIG. 1 and FIG. 2, the anti-jitter fixing structure of the oil pump oil distribution plate of the present invention mainly comprises a hydraulic pump oil distribution plate 1, two first fixing screws 2 and two second fixing screws. 3.
所述的液压泵配油盘的表面上设有高压油口11和低压油口12。通过一条中分线4将液压泵配油盘的表面等分为第一安装面13和第二安装面14，两个安装面均为半圆形面。其中，所述高压油口11位于第一安装面13，所述低压油口12位于第二安装面14。在第一安装面的周缘上开设有两个螺钉孔15，在第二安装面的周缘上也开设了两个螺钉孔15，该四个螺钉孔15的中轴线与液压泵配油盘表面的中心点距离均相等，即落在液压泵配油盘表面的同一个圆周上。该四个螺钉孔15均为沉头螺钉孔。The surface of the hydraulic pump oil distribution plate is provided with a high pressure oil port 11 and a low pressure oil port 12. The surface of the hydraulic pump oil distribution plate is equally divided by a center line 4 into a first mounting surface 13 and a second mounting surface 14, both of which are semi-circular surfaces. The high pressure port 11 is located on the first mounting surface 13 , and the low pressure port 12 is located on the second mounting surface 14 . Two screw holes 15 are defined in the periphery of the first mounting surface, and two screw holes 15 are also formed on the periphery of the second mounting surface. The central axis of the four screw holes 15 is on the surface of the oil pumping plate The center point distances are equal, that is, they fall on the same circumference of the surface of the hydraulic pump oil distribution plate. The four screw holes 15 are countersunk screw holes.
所述的2个第一固定螺钉2分别螺设在第一安装面13上的一个螺钉孔15中，且每个第一固定螺钉2的安装位与液压泵配油盘表面的中心点的连线和中分线4之间的夹角α为45度。The two first fixing screws 2 are respectively screwed into a screw hole 15 on the first mounting surface 13, and the mounting position of each first fixing screw 2 is connected with the center point of the surface of the hydraulic pump oil distribution plate. The angle α between the line and the center line 4 is 45 degrees.
所述2个第二固定螺钉3分别螺设在第二安装面14的一个螺钉孔15中，且每个第一固定螺钉2的安装位与液压泵配油盘表面的中心点的连线和中分线4之间的夹角β为0度<β<45度。The two second fixing screws 3 are respectively screwed into a screw hole 15 of the second mounting surface 14 , and the connection position of each of the first fixing screws 2 and the center point of the surface of the hydraulic pump oil distribution plate are The angle β between the center lines 4 is 0 degrees < β < 45 degrees.
由于本发明的第一安装面上的高压油口分布均匀，受力情况也相对均匀，所以两个第一固定螺钉采用均匀分布方式安装。而第二安装面上的低压油口，其对应的配油盘厚度为中间最薄、逐渐向两侧加厚，因此两个第二固定螺钉采用在两侧靠近中分线的位置安装。Since the high-pressure port on the first mounting surface of the present invention is evenly distributed and the force is relatively uniform, the two first fixing screws are installed in a uniform distribution manner. The low-pressure port on the second mounting surface has the thickness of the corresponding oil distribution plate which is the thinnest in the middle and gradually thickens to both sides, so the two second fixing screws are installed at positions close to the center line on both sides.
本发明主要根据配油盘的工作受力情况，合理的布置了四个固定钉，有效地固定了配油盘的位置，使得配油盘在工作的时候固定，有效防抖动，降低了液压泵的工作噪音。The invention mainly arranges four fixing nails according to the working force of the oil distribution plate, and effectively fixes the position of the oil distribution plate, so that the oil distribution plate is fixed at work, effectively anti-jitter, and reduces the hydraulic pressure. The working noise of the pump.
