Main structure of Series H Right Angle Gearboxes

Main structure of Series H Right Angle Gearboxes

  As the vertical shaft of gearbox is hollow, the strength and rigidity of the  

shaft are raised, and the drive shaft of the working machine can be infixed in the  

hollow shaft to be mounted. The type 7000/DT duplex angular contact ball  

bearings are installed on the upper end of the vertical shaft, and they can bear  

larger downthrust only. The deep groove ball bearing is installed on the down end  

of the shaft，and it is a free end to bear a radial force only. The non-reverse  

coupling is also installed on the upper end of the shaft.   

  The spherical roller bearing is installed on the left end of the horizontal  

shaft, and it can bear a larger radial force and has certain self-aligning function.  

The left end bearing is a free end not to bear any axial force. The deep groove ball  

bearing is installed on the right end of the shaft, and it can bear an axial force  

which results from the gearing towards left or right besides a radial force.

  The upper bearings of the vertical shaft are installed in an upper cover.  

The horizontal shaft and bearings are installed in a bearing block. Moving the  

upper cover and the bearing block you straight can adjust backlash and contact  

pattern of gear pair. There are paper pads between the upper cover or bearing block  

and a box body, and they act as sealing and adjusting.   

  The gear pair, bearings of horizontal shaft and upper bearings of vertical  

shaft adopt spraying oil for lubrication. The pressure oil are given by a pump puller  

of vertical shaft down end, and are carried to all oil site throught multipath pipeline.  

Besides the gears are lubricated by spraying oil of one pipeline, outflow lubricating  

oil from a distribution oil slot of the upper cover lubricate the upper bearings at  

one time lubricate the gears.   

 The gearboxes of type H40 and up externally mounted a cooler. After  

pressure oil cooled in the oil cooler, still flow into all spraying oil pipeline. Clean  

pressure water is connected to the oil cooler, and after flows through heat exchange  

pipes cooled for gear oil and the heat water issues from a return line.
