Preferably, described bearing shell inwall is unthreaded hole.
Preferably, described bearing shell inwall is provided with around the spiral helical flow path of its axis.
Preferably, described active lubrication channel is the spiral helical groove of axis around main shaft, and two end faces of main shaft and the bearing shell section of cooperation are run through at described helical groove two ends.
Preferably, described active lubrication channel comprises and is distributed in the lip-deep axial notch of main shaft, and axial notch two ends connect two sections of main shaft and the bearing shell section of matching.
Preferably, described active lubrication channel comprises along the axial direction of main shaft and is evenly laid in the lip-deep annular recess of main shaft.
Preferably, described active lubrication channel is evenly to lay and the lip-deep spherical crown shape of main shaft pit
The beneficial effect that adopts technique scheme to produce is:
The utility model by arranging initiatively lubrication channel on main shaft, initiatively lubrication channel can be helical groove, axial notch, annular groove or spherical crown shape pit, coordinate with inner surface of bearing bush and form Micropump, at main shaft and bearing shell, relatively rotate in process, can flow by the relative bearing shell of pumping lubricant medium, play initiatively lubricated effect, and under the effect of Micropump, lubricant medium mobile has certain pressure, the lubricating film bearing capacity forming improves greatly, improve cooling effect, increase the service life, and positioning precision is higher.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to Fig. 1 to Fig. 6.
The utility model is disclosed is a kind of guide bearing system of initiatively lubricating, it mainly solves guide bearing lubricant medium of the prior art and does not relatively move, lubricating film pressure-bearing is little, cooling effect is bad, between bearing shell and axle, frictional force is large, the problem that bearing bush abrasion is fast, its key feature is that the active lubrication channel that makes lubricant medium circulation is set on main shaft, lubrication channel coordinates generation Micropump effect with inner surface of bearing bush, in main shaft rotation process, can give lubricant medium certain flowing pressure, under the effect of flowing pressure, can promote on the one hand flowing of lubricant medium, can increase on the one hand in addition the bearing capacity of the lubricating film that lubricant medium forms between main shaft and bearing shell, avoid directly contact friction between main shaft and bearing shell, can extend guide bearing working life, four kinds of embodiments have been specifically related to, specific embodiments is as follows:
Embodiment 1, a kind of guide bearing system (referring to accompanying drawing 1) of initiatively lubricating, comprise bearing support 1, main shaft 2 and bearing shell 3, on described main shaft 2, offer for making the active lubrication channel of lubricant medium circulation, bearing shell 3 inwalls are unthreaded hole or are around the spiral helical flow path of its axis (referring to accompanying drawing 2), bearing shell inwall is unthreaded hole or helical flow path is set, all can with main shaft on active lubrication channel form Micropump, described active lubrication channel is the spiral helical groove 4 of axis around main shaft 2, two end faces of main shaft 2 and bearing shell 3 sections of cooperation are run through at described helical groove 4 two ends, guide bearing adopts water as lubricant medium, between bearing shell and main shaft, form the running that lubricating film carrys out supports main shaft, between existing guide bearing main shaft and bearing shell, be passive lubricated, power by hydraulic machine makes water passive being pressed between main shaft and bearing shell by force, lubrication effect is poor, and the utility model by arranging initiatively lubrication channel on main shaft, initiatively between lubrication channel and bearing shell inwall, form Micropump, under the effect of Micropump, force lubricant medium fully mobile, and the pressure of Micropump can strengthen the anti-pressure ability of lubricating film between main shaft and bearing shell, sufficient lubrication, can avoid transition friction between main shaft and bearing shell, effectively extend guide bearing working life, improve positioning precision.
