Block connects linear drive apparatus on pushing block, and rear cover is equipped in the rear end of housing, and rotation axis stretches out rear cover, the rotation of rear postoperculum
External splines set is fixedly connected in shaft, the belt pulley with internal spline is equipped on outer spline housing, belt pulley passes through
Motor drives, and further, includes at least three groups of bearings on the rotary shaft, one group is located at rotation axis front end, and one group is located at rotation
At axis rear cover, in one group of rotation axis being located near pushing block forepart, further, adjacent each bearing part of every group of bearing is set
There is dottle pin, further, housing forward end is provided with protecgulum, preceding sealing cover is provided in protecgulum, is equipped with preceding sealing cover
There is preceding sealing ring.
The positive advantageous effects of the utility model are：Housing rear end installs pushing block, and linear drives are installed on pushing block
Device, linear drive apparatus can be stepper motor on wear ball-screw, by Driving Stepping Motor make pushing block link main shaft into
The front and rear feed motion of row, ball-screw can realize the distance of movement micron order control, and gap is very between sleeve and housing
One of millimeter, using skeleton oil seal, inside filling hydraulic oil simultaneously pressurizes, and housing is made to be suspended in hydrodynamic oil film, passes through oil
The stability of pump pressure size regulating guarantee main shaft in operation, and feed motion is lubricated.Give up conventional alloys copper-steel
System promotes nested structure, avoids effect of expanding with heat and contract with cold, makes main shaft that can steadily be moved under different temperatures environment；It adopts rear end
With spline housing, by belt the spline housing main shaft that links is driven to be rotated, and is positioned through bearing, reduce driving motor and
Influence of the vibration of belt to main shaft running accuracy is provided with dottle pin between bearing group, including interior dottle pin and outer dottle pin, dottle pin dress
Timing is matched, and increases the axial distance between axial direction, and bearing uses angular contact ball bearing, and stress is good.This mechanical main shaft can be with
Well on numerical control waterwheel.
