Abstract
A crankshaft driving mechanism of a pressing machine is characterized in that a double-herringbone gear at the end of a crankshaft is mounted in a hole on the crankshaft and fixed through a bolt; a double-herringbone gear at the end of an output shaft of a gearbox is mounted in a hole on the output shaft of the gearbox and simultaneously fixed; the gearbox is mounted in a hole on a lathe bed of the pressing machine and simultaneously fixed, so that the double-herringbone gear at the end of the crankshaft is rightly meshed with the double-herringbone gear at the end of the output shaft of the gearbox; a connecting rod and the crankshaft are combined and mounted; and the connecting rod and a sliding block are combined and connected.
Description
Technical field
The utility model relates to the crankshaft driving mechanism of a kind of crankshaft driving mechanism, particularly a kind of forcing press.Belong to the metal forming machinery technical field.
Background technology
Bent axle is the major part of punching machine pressure output, in the real work of forcing press, usually find to be installed in the driven wheel on the bent axle and damage easily and wearing and tearing with the driven wheel phase gear, cause this reason mainly to be: bent axle is in the lowest speed level of transmission system, the moment of torsion that bears is maximum in whole drive system, simultaneously, bent axle also is the part of pressure output, bear bigger impulsive force in the work, in addition in the bent axle processing and fabricating and the error in installing, cause stressed unbalance loading easily, so, easily the gear that is directly installed on the gear on the bent axle and be meshed is with it caused bad influence.
Summary of the invention
The purpose of this utility model is: the crankshaft driving mechanism that a kind of forcing press is provided, overcome that the crankshaft driving mechanism of existing forcing press exists, because the moment of torsion that bears is big, in the bent axle processing and fabricating and the error in installing, cause stressed unbalance loading to cause easily: the defective that easily gear that is directly installed on the gear on the bent axle and be meshed is with it caused irregular wear and damage.
For achieving the above object, the technical scheme that the utility model adopted is achieved in that and will be directly installed on the herringbone bear of the gear employing duplex on the bent axle that the gear that is meshed with it correspondingly adopts herringbone bear; Crankshaft end duplex herringbone bear is installed in the hole above the bent axle, and use bolting, gearbox output shaft end duplex herringbone bear is installed in the hole above the gearbox output shaft, fixing simultaneously, gear-box is installed to press machine tool on one's body in the hole of face, fixing simultaneously, and guarantee crankshaft end duplex herringbone bear and gearbox output shaft end duplex herringbone bear correct engagement, connecting rod and bent axle combination are installed, connecting rod is linked to each other with the slide block combination.
Beneficial effect: because the intermeshing profile of tooth of herringbone bear is a helical teeth, full-depth tooth participates in engagement in proper order in the process of engagement, so, it is few to mesh steady impulsive force, will reduce the defective of local pressure inequality like this, thereby can avoid the excessive or uneven gear damage that is caused of carrying because of local pressure, simultaneously, because chevron shaped gear can be offset the active force from both direction, so the power transmission shaft that is installed in above the gear is difficult for producing axial motion, thereby also correspondingly reduced the accident of the gear damage that may cause thus.
Description of drawings
