Particularly, described rotary body rotating part suit in the enclosure an end and shell between have the gap, described gap forms the first revolution oil pocket, oil-feed extraction channel and first turns round oil pocket and is communicated with.
Reveal in order to prevent hydraulic oil, particularly, the connecting part that has interference fit between described shell and the rotary body, described the second revolution oil pocket is the annular groove that is arranged on described connecting part, at least one fuel-displaced extraction channel is set is communicated with flowline and the second revolution oil pocket.
For the ease of processing, described oil-feed extraction channel and the first revolution oil pocket place of connecting are " T " font passage, and described fuel-displaced extraction channel and the second revolution oil pocket place of connecting are " T " font passage.
Be connected for ease of the lathe spindle with the chuck that surges, the connecting portion of described rotary body has for the nut that detachably is fixedly connected with lathe spindle.
The beneficial effects of the utility model are that the utility model surges chuck with the rotation distributing device, adopts the rolling bearing pair that shell is connected with rotary body, rubs little, durable in use; The first revolution oil pocket and the second revolution oil pocket are set, and when making oil inlet pipe and flowline and lathe spindle transfer, shell is thereupon transfer not; Oil inlet pipe and flowline are coaxial sleeve, and two fuel feed pumps of chuck that prevent from surging drive in the chuck rotary course that surges at lathe and are intertwined; Oil pipe is easy to process, installs very conveniently with the chuck plug-in type of surging, and only install and need 1 hour, and generally oil-proof after installing.
