A FEMALE PART AND METHOD FOR MANUFACTURING FEMALE PARTS |
摘要 |
The present invention relates to a female part intended for top ham- mer-drilling equipment and a method for manufacturing female parts. The female part has a thread in the form of a ridge (2) in a wall (5). The ridge is delimited by a crest (9) and two flanks (10) between which a likewise helical groove (11 ) having a bottom (12) runs. An end the of the groove (11) is defined by a borderline (18), which separates the groove bottom (12) from a part surface (19) formed in the inside of the wall (5), the width of which part surface successively decreases in the peripheral direction, and which has a rotationally symmetrical shape essentially similar to the rotationally symmetrical basic shape of the thread (1). |
