Device, including：Housing, the flange being arranged on housing lower end, the bevel pinion being arranged on input shaft in housing, it is arranged on housing
The bevel gear wheel that is meshed on intermediate solid drive shaft and with described bevel pinion, be arranged in described flange cavity and with described auger tooth
Wheel, by the valve stem nut of spline connection, the valve rod screwing in described valve stem nut, the periphery of described valve stem nut is processed
There is flange face, the upper and lower ends of described flange face are provided with needle roller thrust bearing, are provided with bearing pressure outside described needle roller thrust bearing
Lid.
In a preferred embodiment of the present invention, in described bevel gear wheel, it is machined with involute inner spline.
In a preferred embodiment of the present invention, the upper end nut periphery of described valve stem nut is machined with flower outside involute
Key.
In a preferred embodiment of the present invention, described involute outer spline is meshed with described involute inner spline.
In a preferred embodiment of the present invention, the periphery wall of described valve rod is machined with T-shaped screw thread.
In a preferred embodiment of the present invention, in the middle through-hole of described valve stem nut, it is machined with T-shaped thread groove.
In a preferred embodiment of the present invention, described T-shaped screw thread is meshed with described T-shaped thread groove.
The invention has the beneficial effects as follows：Present configuration advantages of simple, using being machined with the valve stem nut of flange face and push away
Power needle bearing, the transmission of power is carried out separating, reduces the intensity requirement to housing and to the connection spiral shell between housing and flange
The intensity requirement of silk, the rated static load that needle roller thrust bearing can bear in same internal-and external diameter simultaneously is much larger than thrust ball axle
Hold, large carrying capacity, safety coefficient is high, can reach the maximum axial thrust that structure can be born so that maximum axial thrust with
Torque capacity matches.
