断面図、第２図はそのオリフィス部片の断面図である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a hydrostatic bearing having an Oriswiss orifice. Conventional radial hydrostatic bearings, for example, have been implemented as shown in FIGS. 1 and 2. That is, FIG. 1 is a sectional view showing a conventional radial static pressure bearing, and FIG. 2 is a sectional view of an orifice piece thereof.

3c is manufactured, and then the orifice piece 3 is attached to the bearing 2. Note that 5 in the figure is a rotation axis.

軸受２の製作方法では製作費が高くなる欠点があった。However, the pocket hole 3C usually has a diameter of 2 to 4 and a depth of 0.
．． ] It has a small diameter of about 0.3 MM, and 6 to 16 pocket holes are formed for each bearing 2, so this pocket hole 3C is directly machined into the ring-shaped bearing 2. That is difficult. Also, bearing 2
Even if the orifice piece 3 and the orifice piece 3 are made separate, it is difficult to easily machine the orifice piece 3 and the mounting hole for the orifice piece 3 of the bearing 2. Therefore, the conventional method for manufacturing the bearing 2 has the drawback of increasing manufacturing costs.

することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a method for manufacturing a hydrostatic bearing having an Oriais orifice, which eliminates the above-mentioned drawbacks and allows the bearing to be manufactured at low cost.

。In order to achieve the above object, the present invention processes a plurality of orifice holes and pocket holes which are connected to each other in the axial direction and pass through the sheet machine, and the sheet plate is shaped into a cylindrical shape. The bearing is manufactured by rolling it up and joining the joints.
以下実施例を示す第３図および第４図につき説明する。Embodiments will be explained below with reference to FIGS. 3 and 4, which show examples.

。In the present invention, first, as shown in FIG. 3, a letter sheet-shaped bearing 6 is cut to a predetermined size, and a ball filling or the like is processed so as to pass through the bearing 6. Next, the sheet-shaped bearing 6 is rolled into a cylindrical shape using a roll machine or the like, and after being processed into a predetermined cylindrical shape, the joint portions are joined by electric welding or the like, and then -) 1. The joint portion 5a is formed into a cylindrical shape. By finishing it with a grinder or the like and inserting it into the housing 3, a hydrostatic bearing having an orifice restriction is completed.

になる効価を有する。Therefore, in the present invention, instead of manufacturing an orifice piece having conventional orifice holes and pocket holes separately from the bearing and then attaching the orifice piece to the bearing, a plurality of orifice holes and pocket holes are directly attached to the bearing. The orifice holes and pocket holes are machined into a sheet-shaped bearing, and then the sheet-shaped sheet is rolled into a cylindrical shape and the joints are joined, so that the bearing can be easily machined. It has the advantage of reducing production costs.
