Abstract

PURPOSE:To enable to enhance the sealing effect of vanes, by causing initial wear at the decarburized layer formed at the time of normalizing stage during vane manufacturing process at the time of breaking-in of a pump to form the tops of vanes into an arcuate shape conforming to the configuration of a cam. CONSTITUTION:After heat treatment, a vane blank material 12 is subjected to grinding over the entire surface thereof excluding the opposite arcuate portions, so that a relatively soft decarburized layer 13 is left at the opposite arcuate portions of the vane blank material 12. Through running-in of a vane pump, initial wear is caused at the decarburized layers 13, i.e., at the arcuate surfaces at the top of the vanes where the vanes are kept in sliding contact with a cam surface 23, so that the decarburized layers 13 are shaped into an arcuate form conforming to the cam surface 23. Resultantly, it is enabled to enhance the sealing effect of the vanes 10.

[Detailed Description of the Invention] The present invention relates to a vane manufacturing method, and in particular a method for creating a vane that slides on a cam ring into an arc shape that matches the cam shape by utilizing the decarburized layer that occurs when the vane material is normalized. It is related to.

That is, first, a strip material 1 with a rectangular cross section is normalized, then cut into a predetermined size to form a vane material 2, and after heat treatment (quenching, tempering) is performed on this vane material 2, the vane material 2 is defined. While grinding the width dimension W and thickness dimension t, the tip that contacts the cam ring has a radius r.
Grinding is performed on the circular arc surface.

However, in the above-mentioned method, a decarburized layer is generated when the strip material 1 is normalized, and the portion where this decarburized layer is generated does not harden even after heat treatment. When forming an arcuate surface, grinding is performed until the decarburized layer is removed. Therefore, there is a problem that the machining allowance increases and the time required for machining increases.

Moreover, it is difficult to process the arcuate surface of the vane into a shape that matches the cam shape of the cam ring.In particular, as mentioned above, the surface hardness of the arcuate surface is maintained sufficiently by removing the decarburized layer, so it is difficult to process the arcuate surface of the vane into a shape that matches the cam shape of the cam ring. Although the wear of the arcuate surface is small even when the vane is in contact with the vane, it does not conform to the cam shape, which may cause problems with the sealing effect of the vane.

The present invention has been made in view of the above-mentioned conventional problems, and utilizes the decarburized layer produced during normalization to create a circular arc surface of the vane in a shape that matches the cam shape of the cam ring. .

以下本発明の実施例を図面に基いて説明する。Embodiments of the present invention will be described below based on the drawings.

Figure 2 shows the process of manufacturing the vane 10.
Reference numeral 11 denotes a strip material, and this strip material 11 is manufactured to have an oval cross section with arcuate surfaces at both ends. The strip material 11 is normalized to stabilize its structure, and then cut to a predetermined size to form the vane material 12. Such normalizing creates a decarburized layer on the surface of the vane material 12 with a thickness of about 5/100.

Next, the vane material 12 is subjected to heat treatment by quenching and tempering to be hardened, but since the decarburized layer is not hardened, it is not hardened. The heat-treated vane material 12 is ground except for the arcuate surfaces at both ends thereof, and is processed to have a predetermined width dimension W and thickness dimension t. As a result, relatively soft decarburized layers 13 remain on the arcuate surfaces at both ends of the vane material 12.

The vane 10 manufactured in this manner is assembled into the radial groove 21 of the rotor 20 of the known pump assembly shown in FIG. 3, and is run-in. The pump chamber divided by each vane 10 and the cam surface 23 of the cam ring 22 repeats the suction and discharge cycle by the rotation of the rotor 2o, and the suction port 24
The hydraulic oil sucked in is compressed in the pump chamber and discharged from the discharge boat 25, and this discharged oil is introduced into the radial groove 21 of the rotor 20 and presses the vane 10 against the cam surface 23 of the cam ring 22.

The arcuate surface (decarburized layer 13) at the tip of the vane that slides into contact with the cam surface 23 is initially worn to create an arcuate shape that matches the shape of the cam surface 23, thereby enhancing the sealing effect of the vane 10.

In addition, in the above embodiment, since the band material 11 with both ends having circular arc surfaces is used, when assembling the vane 10 to the rotor 20, the vane 10 can be assembled in either direction. There is no need to worry about assembling the vane 10 in reverse. Moreover, since the inner end of the vane 10, which is subjected to the action of the pressure oil introduced into the radial groove 21, is also an arcuate surface, the vane 10
Due to the wedge effect of the pressure oil acting on both inner corners of the vane 10, the vane 10 is centered within the radial groove 21, which prevents leakage of pressure oil due to deviation of the vane 10, and also prevents wear on the side surfaces of the radial groove. This can be prevented.

ことは、本発明にとって必ずしも必要な要件ではなく、
少なくとも一端が円弧面になっていればよいものである
Although the use of the band material 11 with both ends having arcuate surfaces as described above has the above-mentioned advantages, it is not necessarily a necessary requirement for the present invention to have both ends with arcuate surfaces.
It is sufficient that at least one end is an arcuate surface.

As described above, the present invention makes use of the decarburized layer that occurs during normalizing during the vane manufacturing process, and wears out the decarburized layer during the pump's break-in operation in the initial stage, so that the tip of the vane conforms to the cam shape of the cam ring. Since this method creates a circular arc shape, the sealing effect of the vane can be greatly enhanced, and the vane can also be manufactured easily.
