Abstract
The utility model discloses a spindle bearing, including seat circle, blowout patche, roller, housing, installation a plurality of roller between seat circle and the blowout patche, thus seat circle, blowout patche, roller installation are in the same place to the outside of present circle of housing cover and blowout patche, have the round to be used for holding the raceway of roller on the blowout patche, the lateral wall of raceway is the flange, and the bottom of raceway is connected to the inboard lower extreme of flange. The utility model discloses a blowout patche of spindle bearing has the round to be used for holding the raceway of roller on the blowout patche, the upper portion of raceway is with inboard open, and the raceway lateral wall be the flange, the bottom of the inboard lower extreme connection raceway of flange. The beneficial effects of the utility model are that, simple structure, fastness be good, reduce stress concentration, has cancelled the escape of former flange department, through verify many times, can reach the bearing capacity that improves flange intensity, increase the bearing, simplify the turner process, reduce the effect of processing cost.
Description
Technical field
The utility model belongs to spindle field of bearings, relates to the blowout patche of a kind of motor turning bearings and this bearing.
Background technique
Motor turning bearings in use topmost failure mode is the rib fracture of bearing blowout patche, rib major cause of failure is caused to be have tool withdrawal groove (figure mono-) at rib place, have tool withdrawal groove that bearing can be made when Quenching Treatment and grinding to produce stress to concentrate, when bearing uses, rib is easy to rupture from tool withdrawal groove under alternating stress effect.
Summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides that a kind of structure is simple, soundness good, reduces the blowout patche of motor turning bearings that stress concentrates and this bearing.
The utility model is achieved by the following technical solution:
Motor turning bearings of the present utility model, is characterized in that: comprise seat ring, blowout patche, roller, case, installs several rollers between seat ring and blowout patche, and case is enclosed within the outside of seat ring and blowout patche thus seat ring, blowout patche, roller is installed together; Blowout patche has a circle for holding the raceway of roller, the outer side wall of raceway is rib, and the lower end inside rib connects the bottom of raceway.
Motor turning bearings of the present utility model, the joint bottom the rib inside lower end of blowout patche and raceway is provided with transition arc.
The blowout patche of motor turning bearings of the present utility model, is characterized in that, blowout patche has a circle for holding the raceway of roller, the top of raceway and inside, the outer side wall of raceway is rib, and the lower end inside rib connects the bottom of raceway.
The blowout patche of motor turning bearings of the present utility model, the joint bottom the rib inside lower end of blowout patche and raceway is provided with transition arc.
The beneficial effects of the utility model are, structure is simple, soundness good, reduce stress concentrates, the tool withdrawal groove (Fig. 1) at rib place before eliminating, through multiple authentication, can reach improve rib intensity, the bearing capacity that increases bearing, the effect that simplifies turner operation, cut down finished cost.
Accompanying drawing explanation
Fig. 1 is primitive axis circle schematic diagram, and Fig. 2 is blowout patche schematic diagram of the present utility model.Fig. 3 is bearing schematic diagram of the present utility model.
In figure, 01 seat ring, 02 blowout patche, 03 raceway outer side wall, 04 roller, 93 cases, 05 transition arc, the bottom of 06 raceway, 07 tool withdrawal groove.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Motor turning bearings of the present utility model, comprises seat ring 01, blowout patche 02, roller 04, case 93, installs several rollers between seat ring and blowout patche, and case is enclosed within the outside of seat ring and blowout patche thus seat ring, blowout patche, roller is installed together; Blowout patche has a circle for holding the raceway of roller, the outer side wall 03 of raceway is rib, and the lower end inside rib connects the bottom of raceway.Bottom the rib inside lower end of blowout patche and raceway, the joint of 06 is provided with transition arc 05.The top of blowout patche raceway and inside.
The blowout patche of motor turning bearings of the present utility model, blowout patche has a circle for holding the raceway of roller, the top of raceway and inside, the outer side wall of raceway is rib, and the lower end inside rib connects the bottom of raceway.Joint bottom rib inside lower end and raceway is provided with transition arc.
The beneficial effects of the utility model are,
1, avoid or reduce rib place thermal stress concentrate
During Vehicle Processing angular place have stress concentrate, eliminate tool withdrawal groove, do not have Vehicle Processing wedge angle, the raceway of blowout patche and the joint of rib are provided with transition arc.Avoid producing stress when heat treatment and grinding to concentrate, add rib intensity, improve the bearing capacity of bearing.
2, Vehicle Processing decreases a procedure, simplifies turnery, cuts down finished cost about 20%.
