Abstract
The invention discloses an eccentric shaft for the core of a totally-hermetic compressor. The eccentric shaft comprises a crank (1); two sides of the crank (1) are respectively provided with a main journal (2) and an auxiliary journal (3); the main journal (2) is connected with a thrust surface I (6) at one side of the crank (1), the auxiliary journal (3) is connected with a thrust surface II (4) at the other side of the crank (1), and an arc chute (5) is arranged at the lower part of the thrust surface II (4). The eccentric shaft provided by the invention enables contact between the eccentric shaft and the thrust surfaces to be reduced, so processing quality is guaranteed and noise of the compressor is reduced.
Description
Technical field
The present invention relates to a kind of eccentric shaft of totally-enclosed compressor movement.
Background technique
The eccentric shaft of totally-enclosed compressor part movement is one of the major part of the core part of totally-enclosed compressor part, and its processing dimension and morpheme are had relatively high expectations.A large amount of evidences, thrust surface directly has influence on the noise of compressor to the perpendicularity of main journal, but because the eccentric shaft perpendicularity has relatively high expectations, the consumption of emery wheel and trimmer is still very big, and processing has does not slightly note the risk of scrapping because perpendicularity is overproof with regard to existing.
Summary of the invention
The invention provides a kind of eccentric shaft of totally-enclosed compressor movement, it can reduce the contact of eccentric shaft thrust surface, thereby guarantees quality of processing, reduces the noise of compressor.
The present invention has adopted following technological scheme: a kind of eccentric shaft of totally-enclosed compressor movement, it is characterized in that it comprises crank throw, be respectively equipped with main journal and countershaft neck in the both sides of crank throw, main journal is connected with the thrust surface I of crank throw one side, the countershaft neck is connected with the thrust surface II of crank throw opposite side, is provided with curve bath in the bottom of thrust surface II.
Described main journal and countershaft neck and crank throw are set to one.Described curve bath is set to the bar-shaped trough of circular arc, and the circular shape of bar-shaped trough is corresponding with the shape of countershaft neck.
The present invention has following beneficial effect: adopted above technological scheme, main journal of the present invention is connected with the thrust surface I of crank throw one side, the countershaft neck is connected with the thrust surface II of crank throw opposite side, bottom in the thrust surface II is provided with curve bath, so not only can guarantee the perpendicularity of eccentric shaft processing, reduce the consumption of emery wheel, and can reduce the surface of contact of thrust surface II, reduced the noise of compressor complete machine.
