As further innovation of the present utility model, on the outer side surface of described abutment sleeve, annular array is provided with insert sheet for positioning corresponding to some and described guiding groove, the cross section of described insert sheet for positioning is arc, and the thickness of insert sheet for positioning is less than or equal to the degree of depth of guiding groove.
The beneficial effects of the utility model are:
1, the utility model innovation arranges guide groove structure on bearing, make bearing inside casing and housing can uniform stressed while installation, dismounting, bearing can be effectively prevented to be damaged when installing or dismantle, keyway coordinates better compared to traditional ring surface contact stabilization simultaneously, is not easy to allow bearing run-off the straight.
2, the guiding groove on bearing housing coordinates with instrument, is led to mobile axis during bearing press mounting by guiding groove, reduces the incidence rate that bearing tilts to install.
3, instrument of the present utility model is compared to traditional bearing installing tool, higher to the degree of restriction of bearing, stability when press-fiting is better, insert sheet for positioning can be inserted in rotation hole in advance, the cylindrical consisted of insert sheet for positioning coordinates with rotation hole inwall, improving the coaxality of this instrument and rotation hole, preventing bearing axis when press-fiting from offseting, cause scrapping of bearing or rotation hole.
