Abstract
The utility model relates to a crankshaft mechanism, in particular to a short-stroke crankshaft mechanism for a press. The short-stroke crankshaft mechanism is used for the press, and comprises a crankshaft, wherein a flywheel is sleeved on the head part of the crankshaft; the flywheel and the crankshaft are positioned through a running key; a middle sleeve is arranged between the running key and the flywheel; an inner bushing is arranged at the left side end of the middle sleeve, and an outer bushing is arranged at the right side end of the middle sleeve; the right side end of the crankshaft is fixedly connected with the flywheel through an end cover; and the stroke of the crankshaft is 15mm. The short-stroke crankshaft mechanism for the press is compact in structure and excellent in operational performance.
Description
Technical field
The utility model relates to a kind of crank mechanism, relates in particular to a kind of little stroke press crankshaft mechanism, is used for forcing press.
Background technology
The bent axle of forcing press all is big stroke in the prior art at present, and complex structure, and stability is not high relatively.
