る。FIG. 2 shows a hermetic compressor manufactured according to the present invention, in which an electric motor 11 is supported at the upper part of a casing 10 that can be divided into upper and lower parts, and the lower end side of a shaft 12 that extends downward from the electric motor 11. An eccentric large-diameter portion 13 is integrally formed in the. The shaft 12 is supported by a main bearing 15 and a sub-bearing 16 of the compression device 14 so as to sandwich the large-diameter portion 13 therebetween.

７内に圧縮室を形成している。The compression device 14 includes a main bearing 15, a sub-bearing 16, and a cylinder 17 located between these, and includes a roller 18 fitted onto the large diameter portion 13, and a roller 18 that comes into elastic contact with the roller 18. Due to the cooperative action of the blade 19, the cylinder 1
A compression chamber is formed within 7.

動機１１から延びる軸１２が通る軸孔２０を有する略円
筒形のボス部２１と、−面にボス部２１を受ける凹部２
２を設けるとともに上記軸孔２０より大径の孔２３を有
する平板部２４とを摩擦圧接することで作られている。As shown in FIG. 1, the main bearing 15 of the compression device 14 includes a substantially cylindrical boss portion 21 having a shaft hole 20 through which the shaft 12 extending from the electric motor 11 passes, and a recess 2 that receives the boss portion 21 on the negative side.
2 and a flat plate portion 24 having a hole 23 with a larger diameter than the shaft hole 20 are frictionally welded together.
上記平板部２２の孔２３のボス部２１に囲まれる部分は

ぼり取り工程を必要としない。In order to make the main bearing 15, the boss part 21 is placed in the recess 22 of the flat plate part 24 so that the axes of the shaft hole 20 and the hole 23 are aligned, and the boss part 21 and the flat plate part 24 are friction welded. Although it is made into one piece, the molten slag that occurs due to this friction welding,
25 , 26 are formed between the recess 22 and the outer surface of the boss 21 and between the end surface of the boss 21 and the edge of the hole 23 of the flat plate 24 , so that the melting holes 25 , 26 are formed on the shaft 12 . Therefore, there is no need for a separate process for removing the melting burrs 25 and 26.
また平板部２４の孔２３にボス部２１との間に座ぐり形
状が形成されるので平板部に座ぐり加工等の機械加工を
施す必要がなくなる。Further, since a counterbore shape is formed between the hole 23 of the flat plate part 24 and the boss part 21, there is no need to perform machining such as counterboring on the flat plate part.
なお上記実施例では、平板部２４に凹部２３を設け、こ
の凹部２３にボス部２１を設けるようにしたが、第３図

能となるという効果を奏する。As described above, according to the present invention, since the bearing is formed by setting the inner diameter of the flat plate part larger than the inner diameter of the boss part, molten burrs do not occur on the inner diameter of the boss part, and therefore, unlike conventional bearings, burrs can be removed. Since the process can be omitted and machining such as counterboring can be omitted, the cost of the bearing can be reduced.
This has the effect of simplifying the process and reducing the cost of the entire device.
