Described step surface is the end face of the groove that is provided with in the Bearing Installation position on the bearing support housing endoporus circumferential surface, and described bearing housing is embedded in the described groove in the both sides of Bearing Installation position, cooperates with the end face block of groove.
Described diaxon bearing sleeve is provided with the retaining edge of extending to axis direction away from the end face of Bearing Installation position.
The endoporus on described bearing housing retaining edge is used for being rotatably assorted with rotating shaft, described bearing support housing be provided with bearing housing and Bearing Installation position between the lubricating cup that communicates of the bearing cavity that forms.
The technological scheme of the bearing composite structure that the utility model provides is as follows: a kind of bearing composite structure, described step surface is the end face that the groove of contacting point setting is installed with bearing outer ring on the bearing support housing endoporus circumferential surface, described bearing outer ring and bearing housing all are embedded in the described groove, cooperate with the end face block of groove.
Described diaxon bearing sleeve is provided with the retaining edge of extending to axis direction away from the end face of bearing, forms the bearing cavity between diaxon bearing sleeve and the bearing.
The endoporus on described bearing housing retaining edge is used for being rotatably assorted with rotating shaft, and described bearing support housing is provided with the lubricating cup that communicates with the bearing cavity of bearing housing and bearing formation.
Bearing support of the present utility model and composite structure thereof are provided with step surface in the bearing outer ring both sides on the circumferential surface of bearing support housing endoporus, and corresponding bearing housing is set replaces traditional spacer structure, because the surface of contact of bearing housing and bearing support housing endoporus circumferential surface tails off, adding only needs to carry out fine finishing at the rigging position of bearing outer ring and bearing housing and bearing support housing man-hour, all the other position roughing just can be satisfied the requirement of assembling, greatly reduced amount of finish, improved work efficiency, also reduce simultaneously the use amount of material, saved cost.
As further improvement, the utility model adopts and on bearing support housing endoporus circumferential surface groove to be set, and bearing housing and bearing outer ring all are embedded in form in the groove.
Further, bearing housing is provided with the retaining edge of extending to axis direction away from the end face of bearing, the endoporus on retaining edge is used for being rotatably assorted with rotating shaft, bearing housing and bearing form less cavity, make lubricating grease can directly arrive bearing portion, improve lubricating efficiency, reduced the use amount of lubricating grease.

Fig. 1 is the schematic representation of traditional bearing composite structure;
Fig. 2 is the structural representation of the utility model embodiment's bearing composite structure;
Fig. 3 is the left view of the utility model bearing composite structure.
Embodiment
As Fig. 2～Figure 3 shows that structural representation of bearing support of the present utility model and bearing composite structure thereof, bearing support comprises split type bearing support housing, be provided with step surface in place, both sides, Bearing Installation position on the bearing support housing endoporus side face, both sides, Bearing Installation position are provided with bearing housing 2, and bearing housing 2 cooperates with the step surface block.The bearing composite structure comprises having two-part split type bearing support housing 5 up and down, and be installed on the bearing 4 that has inner ring and outer ring in the bearing support housing, the both sides, outer ring of bearing 4 are provided with bearing housing 2, be provided with step surface in place, bearing both sides on the bearing support housing 5 endoporus side faces, bearing 4 is assemblied in the endoporus of split type bearing support by two bearing housing axially locating of its both sides.With bearing outer ring the contacting point is installed on the bearing support housing 5 endoporus circumferential surfacies of the utility model preferred embodiment and is made as groove, step surface is the end face of groove, and bearing outer ring and bearing housing 2 all are embedded in the described groove, and bearing housing 2 cooperates with the end face block of groove.
Bearing housing 2 is provided with the retaining edge of extending to axis direction away from the end face of bearing 4, and the endoporus on its retaining edge is used for being rotatably assorted with rotating shaft, and bearing support housing 5 is provided with the lubricating cup 3 that communicates with the cavity of bearing housing 2 and bearing outer ring formation.
Bearing support of the present utility model and bearing composite structure thereof are provided with step surface in the bearing outer ring both sides on the circumferential surface of bearing support housing endoporus, and corresponding bearing housing is set replaces traditional spacer structure, because the surface of contact of bearing housing and inner hole of bearing seat circumferential surface tails off, adding only needs to carry out fine finishing at the rigging position of bearing outer ring and bearing housing and bearing support housing man-hour, all the other position roughing just can be satisfied the requirement of assembling, greatly reduced amount of finish, improved work efficiency, also reduced simultaneously the use amount of material, provided cost savings.
