Abstract
The utility model relates to a bearing axial pretensioning means. The utility model belongs to the technical field of mechanical engineering. A bearing axial pretensioning means includes that bearing cap, pretension lid, pretension screw and lock are female, the bearing inner race terminal surface covers axial positioning with the pretension, and the pretension screw covers the axial top through the pretension and pushes away bearing inner race, realizes bearing axial pretension and locks by the lock is female. The utility model has the advantages of the design science, convenient to use, the adjustment is simple, safe and reliable, but wide application in the installation pretension of bearings such as angular contact ball bearing, tapered roller bearing.
Description
Technical field
The utility model belongs to mechanical engineering technical field, particularly relates to a kind of bearing shaft to pre-tightening mechanism.
Background technique
Bear the bearing of thrust load, as angular contact ball bearing, tapered roller bearing, not only need axially locating when mounted, also want axial pretightening, to ensure the steady and bearing life in operation process.
At present, the axial pretightening of bearing adopts packing ring adjustment and nut to adjust two kinds of modes usually.These two kinds of adjustment modes all need to unload lower ball cover, complex procedures.Packing ring adjustment is also subject to the restriction of single-piece gaskets thickness, and pretensioning effect is stronger to workman's technology dependence.
Summary of the invention
The utility model provides a kind of bearing shaft to pre-tightening mechanism for solving in known technology the technical problem that exists.
The purpose of this utility model is to provide a kind of design science, easy to use, and adjustment is simple, safe and reliable, can be widely used in the axial pretightening of the bearing such as angular contact ball bearing, tapered roller bearing.
The technological scheme that the utility model bearing shaft is taked to pre-tightening mechanism is:
A kind of bearing shaft, to pre-tightening mechanism, is characterized in: bearing shaft comprises bearing cap, pretension lid, pre-loading screw and locknut thereof to pre-tightening mechanism; Bearing outer ring end face and pretension lid axially locating, pre-loading screw, by the axial pushing tow bearing outer ring of pretension lid, realizes bearing axial pretightening and by nut-locking.
The utility model bearing shaft can also adopt following technological scheme to pre-tightening mechanism:
Described bearing shaft, to pre-tightening mechanism, is characterized in: there is tapped hole at bearing cap center, and pre-loading screw is installed on the tapped hole at bearing cap center.
Described bearing shaft, to pre-tightening mechanism, is characterized in: there is annular boss at pretension lid edge, and boss internal diameter is greater than the outer warp of bearing inner race, by raised head face pushing tow bearing outer ring end face.
The advantage that the utility model has and good effect are:
Bearing shaft is to pre-tightening mechanism owing to have employed the brand-new technological scheme of the utility model, and compared with prior art, the utility model adopts the pretension lid with boss to carry out axially locating to bearing, and this mechanism has the reliable advantage in location; Pre-loading screw, by the axial pushing tow bearing outer ring of pretension lid, can realize adjustment and the correction of pretightening force; Locknut is locked pre-loading screw, can, effectively to locking, use reliable.The utility model design science, easy to use, adjustment is simple, safe and reliable, can be widely used in the axial pretightening of the bearing such as angular contact ball bearing, tapered roller bearing.

Embodiment
For model utility content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Accompanying drawings 1.
Embodiment 1
A kind of bearing shaft comprises bearing cap, pretension lid, pre-loading screw and locknut thereof to pre-tightening mechanism; Bearing outer ring end face and pretension lid axially locating, pre-loading screw, by the axial pushing tow bearing outer ring of pretension lid, realizes bearing axial pretightening and by nut-locking.
There is tapped hole at bearing cap center, and pre-loading screw is installed on the tapped hole at bearing cap center.There is annular boss at pretension lid edge, and boss internal diameter is greater than the outer warp of bearing inner race, by raised head face pushing tow bearing outer ring end face.
The specific implementation process of the present embodiment:
Bearing is installed in rack mounting apertures, and brearing bore is set on axle journal, load pretension lid at rack mounting apertures, by screw bearing cap is in place and pre-loading screw and locknut thereof are installed on bearing cap.Tighten lock screw, pretension lid, bearing can be in place vertically and to bearing pre-tightened.After being adjusted to corresponding pretightening force, by locknut, pre-loading screw is locked.The correction of bearing pre-fastening when pre-loading screw and locknut also can be used for keeping in repair.
The utility model design science, easy to use, adjustment is simple, safe and reliable, can be widely used in the axial pretightening of the bearing such as angular contact ball bearing, tapered roller bearing.
