Description
Technical field
The present invention relates to bearing block, specially a kind of taper roll bearing bearing block.
Background technology
Bearing block is one of conventional machine components of mechanical transmission fields, and almost the place with bearing can all be related to axle
Bearing.In the last few years, the requirement to automobile constant pitch fuel consumption conservation was increasingly increased, for for supporting speed change mounted thereto
For the taper roll bearing of the rotary shaft of device device or differential gearing, it is desirable to reduce its driving torque, wherein, as subtracting
The method of the driving torque of roundlet taper roller bearing, the method used is in the track of the rolling surface of taper roller or Internal and external cycle
Implement projection on face to reduce rolling friction.But, as described above, although by implementing raised on rolling surface or orbital plane,
The driving torque of the taper roll bearing can be reduced, still, on the other hand, due to contact of the rolling surface with orbital plane can be increased
Surface pressure, therefore, can worry to reduce the life-span of rolling bearing.Particularly, in the less bearing of key dimension, due to circular cone rolling
Son roller length it is shorter, accordingly, there exist the life-span can with the increase of projection amount significantly reduced situation, therefore, how to improve
The structure of bearing block, increases its practicality, and automaticity is high, so that the service life for improving bearing block is in the art
Technical staff needs the key technical problem solved at present.
The content of the invention
It is an object of the invention to provide one kind usher to seat roller bearing units seat, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the present invention provides following technical scheme：A kind of taper roll bearing bearing block, including bearing
It is provided with the right side of seat, the bearing block below outer ring, the outer ring and is provided with inner ring, is small blade of a sword portion on the left of the inner ring, it is described
It is to be provided with the middle of outer peripheral face, the inner ring and the outer ring to be provided with circular cone rolling around big blade of a sword portion, the inner ring on the right side of inner ring
Son, the taper roller is provided with coniform roller surface, the taper roller close to position with the outer ring, the inner ring
On be connected with retainer, be provided with pad on the outside of the inner ring, described pad one end is provided with claw, the claw and is provided with
Engaging protuberances and engaging recessed part, the pad are close to position with the inner ring and are provided with inner ring end face, the inner ring end face set
It is equipped with the middle of flange end face, the bearing block and is provided with other side's part.
It is preferred that, the taper roller is provided with several, improves operating efficiency.
It is preferred that, the claw is multiple along the pad spaced set, improves operating efficiency.
It is preferred that, the engaging recessed part in a ring, makes its outer peripheral face of more fitting on the outer peripheral face, it is ensured that structure it is tight
Close property.
It is preferred that, the engaging protuberances band fillet makes its inner ring of more fitting, it is ensured that the compactness of structure.
It is preferred that, the gasket surface is provided with nitration case, makes device more stable.
It is preferred that, the thickness of the pad is 0.3mm-0.8mm, reduces the error of device, makes device operating efficiency higher.
It is preferred that, other side's part is set to the pinion shaft of differential gear, it is ensured that the normality of working condition.
Compared with prior art, the beneficial effects of the invention are as follows：This kind of taper roll bearing bearing bearing block, it is interior by making
Circle is chimeric with other side's part (such as the drive pinion shaft or differential case of differentiator), makes the end of the big blade of a sword portion side of inner ring
Face and the end contact of the flange part radially extended from other side's part, and outer ring is pressed to flange end surface side, and apply suitable
When bearing prepressing force.Also, by so applying appropriate bearing prepressing force, to extend the fatigue life of taper roll bearing, and
Improve the engagements of the gear of geared system such as differentiator and prevent the trouble such as gear destruction.However, turning to geared system input is high
During square, other side's part is distorted, so as to produce slip between inner ring end face and flange end face.Now, stick-slip noise is produced,
And worn and torn in inner ring end face and flange end face.So when inner ring end face or flange end face wear and tear, it can turn into interior
The reason for circle separates with outer ring and reduces bearing prepressing force.Therefore, the setting of pad inhibits inner ring end face and the mill of flange end face
It is abrasion in order to prevent inner ring end face and flange end face and at two ends to damage and bearing prepressing force is not reduced the taper roll bearing
The part of sandwiched pad between face.In addition, the pad has fillet part in outer peripheral edge, by the way that cylindrical portion press-in is fitted into inner ring
The outer peripheral face in big blade of a sword portion and it is integrated with inner ring.
