Description
Technical field:
The utility model relates to a kind of high-power locomotive steering framing wheel that is applied to the elastic coupling flexible coupling in the motor driven systems, belongs to rolling stock structural design field.
Background technique
In engine truck is taken turns motor driven systems, driving gear generally is directly installed in the traction electric machine rotating shaft, need not adopt elastic coupling flexible coupling, but on high-power locomotive, power of traction motor reaches 1600kW, as adopts traditional motor driven systems, driving gear is installed in two bearing outer ends of motor by the motor shaft cantilever, motor shaft produces crookedly during master and slave gear engagement, causes the master gear unbalance loading, and the drive bearing of traction electric machine driving end will bear very big load simultaneously.To shorten greatly the working life of master and slave gear and traction electric machine bearing, increase the repair and maintenance amount.
At present, that adopts in the mechanism of various transmission torques mostly is gear coupling, pin-type load elastic coupling flexible coupling and metal diaphragm coupling etc., adopts spline coupling band socket live axle more, and complex structure is relatively poor to the compensation performance of skew to each.This class coupling all is made up of multiple elements simultaneously, complex structure, and the repair and maintenance inconvenience, mostly axle was to fix by the key connecting of interference fit with connecting of coupling, carried out fastening connection by bolt between two half-couplings.The compensation that the power that coupling can transmit reaches various axial displacements, radial displacement and angular deflection all is restricted, and can not satisfy engine truck and take turns motor driven systems each specific (special) requirements to rigidity, displacement, deflection.
The model utility content
For satisfying of the designing requirement of high-power locomotive steering framing wheel to motor driven systems, the utility model aim to provide a kind of simple in structure, the repair and maintenance amount is little, have larger axis to, radially, the elastic coupling flexible coupling of bending resistance and torsional rigidity, be used for connecting traction electric machine axle and driving gear shaft, the high pulling torque between transmitting tractive motor and the driving gear.
The technical solution of the utility model is that described elastic coupling flexible coupling comprises left half-coupling and right half-coupling, it is characterized in that the inwall of described left and right half-coupling is provided with corresponding arcuate structure, makes that part forms cavity between the left and right half-coupling.
As preferred version, the inwall contact segment of left and right half-coupling forms toroidal surface, and is coupled to each other by welding manner.
As preferred version, in the elastic coupling flexible coupling described in the utility model, be provided with tapped hole that radially passes left half-coupling and the oil hole of being located at right half-coupling center hole both sides; Left side half-coupling has the profile of tooth end face tooth that is meshed with gear shaft end face tooth, and right half-coupling is provided with and the friction tight tapering of the taper hole of motor shaft end.
According to the described preferred version of embodiment, this tapering is preferably 1: 30 degree.
Design principle of the present utility model is, described elastic coupling flexible coupling comprises left half-coupling and right half-coupling, described coupling inwall is designed to arcuate structure, by adjusting the arcuate structure size, make elastic coupling flexible coupling axially, radially, antitorque and flexural rigidity meets design requirement; Left side half-coupling has profile of tooth end face tooth, be meshed with pinion shaft end face tooth, right half-coupling has 1: 30 tapering, taper hole drive fit with motor shaft end, different connecting modes is adopted at the coupling two ends, be convenient to the installation and maintenance of whole system, can both transmit big moment of torsion and good centering performance is arranged simultaneously; Welding manner is adopted in connection between the relative toroidal surface of two half-couplings; When needing the dismounting coupling, oiling in two oil holes avoids the coupling conical surface to pull when dismounting.Tapped hole is arranged in the elastic coupling flexible coupling, can axially fasten by bolt and gear shaft.
Elastic coupling flexible coupling described in the utility model makes the motor shaft output terminal need not the direct and driving gear shaft resilient connection of bearing, can transmit bigger torque, and have bigger axially, radially, bending and torsional stiffness, simultaneously, it is big that the end face tooth connects bearing capacity, the geometrical shape of tooth portion is felt relieved each other with respect to spin axis, has guaranteed that the height that connects is concentric, is applicable to the drive system of high-power locomotive bogie.And this elastic coupling flexible coupling installation dimension is little, simple in structure, and repair and maintenance is convenient, long service life.

Embodiment
As shown in Figure 1, the elastic coupling flexible coupling that present embodiment provides is formed by two special rosette assembly weldings, comprises left half-coupling 1, right half-coupling 2, radially passes the tapped hole 6 of Left-wing Federation's axial organ 1 and be located at the oil hole 7 of right half-coupling 2 center holes 13 both sides; The inwall of two half-couplings is an arcuate structure 5, forms cavity 14; A left side half-coupling 1 and driving gear shaft 9 adopts profile of tooth end face teeth 3 to be connected, tapering 4 and motor shaft 10 drive fits of right half-coupling 2 by 1: 30, about the employing welded connection is together between the relative toroidal surface 8 of two half-couplings.
During use, by M52 MA=1000Nm type king-bolt 11 and DIN6912 M30 MA=700Nm type bolt 12 that driving gear shaft and motor shaft is affixed, described elastic coupling flexible coupling one end adopts end face tooth connecting mode, the other end adopts cone, be convenient to connect motor shaft and driving gear shaft, have larger axis to, radially, bending resistance and torsional rigidity, the high pulling torque between transmitting tractive motor and the driving gear.Under static state, motor shaft is concentric with gear shaft, has good centering performance, be in operation can adapt to produce between machine shaft and the driving gear shaft each to micro-displacement and deflection, it is simple in structure, repair and maintenance is convenient, long service life.
