Abstract
A transmission shaft of a pressing machine relates to a mechanical equipment, in particular to the pressing machine. The utility model consists of a crankshaft and a sprocket, the sprocket is connected on a sprocket shaft concentrically, the tail part of the crankshaft is connected with a transmission shaft concentrically, and a universal coupling of the cross-point transmission shaft type is connected between the sprocket shaft and the transmission shaft. The utility model changes the transmission shaft into the universal coupling of the cross-point transmission shaft type, having the function of compensating the relative deviation of the two shafts in case the shaft lines of the two transmission devices are not in the same straight line, therefore, the nonconcentricity of the crankshaft center and the sprocket center is not required to be less than 0.03, thereby the utility model reduces the processing difficulty, and the abrasion does not cause the potential safety hazard after the pressing machine works for a long time.
Description
Technical field
The utility model relates to a kind of plant equipment, particularly forcing press.
Background technology
In forcing press power transmission process, the bent axle afterbody passes to power on the pair of sprocket by power transmission shaft, by them the synchronized movement of bent axle is passed to cam controller.In this process, the nonconcentricity that requires crankshaft center and centre of sprocket is less than 0.03, this has just strengthened the difficulty of processing of forcing press, if the nonconcentricity of crankshaft center and centre of sprocket is too big, then the athletic meeting of bent axle causes drive shafts fracture, can't transmit signal to cam controller, even can cause security incident; Forcing press is after working long hours simultaneously, and collar bush will inevitably wear and tear, and this also causes the nonconcentricity of crankshaft center and centre of sprocket to become big, and forcing press exists potential safety hazard.
The utility model content
The utility model purpose is a kind of a kind of transmission device that is easy to process, avoid the forcing press of potential safety hazard of design.
The utility model comprises bent axle, sprocket wheel, and sprocket wheel is connected on the sprocket shaft with one heart, and the afterbody of bent axle connects power transmission shaft with one heart, is connected universal coupling with spider between sprocket shaft and the power transmission shaft.
The utility model changes power transmission shaft into universal coupling with spider, for the axis of two transmission devices situation on same straight line not, performance with compensation diaxon relativity shift, so just needn't require the nonconcentricity of crankshaft center and centre of sprocket less than 0.03, reduced difficulty of processing, wearing and tearing can not cause potential safety hazard yet after forcing press worked long hours.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Specific embodiment
As shown in the figure, sprocket wheel 1 is connected on the sprocket shaft 2 with one heart, and the afterbody of bent axle 3 connects power transmission shaft 4 with one heart, is connected universal coupling with spider 5 between sprocket shaft 2 and the power transmission shaft 4.
Claims (1)
1, a kind of transmission device of forcing press comprises bent axle, sprocket wheel, it is characterized in that sprocket wheel is connected on the sprocket shaft with one heart, and the afterbody of bent axle connects power transmission shaft with one heart, is connected universal coupling with spider between sprocket shaft and the power transmission shaft.
