The two ends of each bearing shell described in the utility model are processed with a guiding groove respectively near the side of bearing spider, and guide pad I and guide pad II are inserted in guiding groove.
Adjustment back-up ring I described in the utility model and the end face outside of adjustment back-up ring II are processed with four uniform adjustment circlip grooves respectively.
During use, bearing spider is installed in the tank wall hole of component of machine, then adjusts the gap between bearing housing and bearing shell.When the excesssive gap of bearing housing and bearing shell, spanner inserts in the end face adjustment back-up ring slotted eye of adjustment back-up ring I, suitably unscrew adjustment back-up ring I, then screw up with a wrench adjustment back-up ring II, now bearing shell moves along guide pad under the effect of thrust, and under the effect of the conical surface, bearing shell is moved radially, thus make the gap smaller between bearing shell and bearing housing, adjust complete tightening and adjust back-up ring I; Otherwise, when the gap between bearing housing and bearing shell is too small, by the adjustment of above-mentioned contrary direction.
The utility model has the advantages that apparent, be mainly manifested in:
1, the utility model can realize the adjustment in the gap between bearing housing and bearing shell, ensure that lathe, the stationarity of equipment moving parts transmission and transmission accuracy.
2, the utility model can be used as overall parts and uses, handling, easy to maintenance, saves maintenance cost, increases work efficiency.
The utility model has novel structure, it is easy to process, Use Adjustment is convenient, improve working efficiency, improve the advantages such as transmission accuracy, and it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
