Summary of the invention
The utility model provides a kind of new-type rolling bearing grinding machine movable end support device, and it has overcome the deficiency that current existing bearing grinding machine movable end supporting structure exists, and it has simple in structure, and economy and durability is lightweight, feature easy for installation.
In order to address the above problem, the technological scheme that the utility model adopts is: a kind of new-type rolling bearing grinding machine movable end support device, it is characterized in that, comprise bearing supporting body and quill shaft, described bearing supporting body comprises rolling bearing, bearing upper cover, bearing base, described rolling bearing is arranged on the inside of the bearing housing of bearing upper cover and bearing base composition, the rolling bearing of described bearing supporting body is nested with on quill shaft, described rolling bearing is outer spherical surface aligning biserial cylindrical roller bearing, the bearing outer ring of described rolling bearing is sphere, the both sides of described bearing outer ring arrange rib, on the bearing inner race of described rolling bearing without rib, the width of described bearing inner race is greater than the width of bearing outer ring, the inside of described bearing base has the inner ball surface matching with the bearing outer ring of rolling bearing, the left side at the position combining with quill shaft at rolling bearing is provided with bearing inner race fixing device, described bearing inner race fixing device is nested with on the circular groove of offering on quill shaft.
Described bearing inner race fixing device is two symmetrically arranged semicircle holding rings, and the two ends of the circular holding ring of two halves are bolted respectively and form a complete circular holding ring together.
The inner ball surface center of described bearing base offers center oil groove.
The beneficial effects of the utility model are: compared to the prior art a kind of new-type rolling bearing of the utility model grinding machine movable end support device, has following outstanding beneficial effect:
1, the utility model has been cancelled existing bearing grinding machine movable end supporting structure roller structure, eliminates because processing coordinates and is difficult to ensure card, occurs that roller fluted shaft is to decentraction, and roller is put to enter phenomenon.Also avoided grinding machine in operation process, roller is stuck in roller groove, does not rotate simultaneously, causes grinding machine vibration, and the generation of the de-groove phenomenon of roller occurs when even severe.
2, the utility model has adopted circular holding ring for holding rigid bearing inner ring, has effectively avoided bearing that the generation of play problem occurs on quill shaft.
3, the utility model is owing to having cancelled roller structure, and this place also, without sealing is being set, can say the generation of thoroughly having stopped to enter grey phenomenon, and dust easily enters in roller chamber along roller slot number, pollution lubricating fat etc., and sealing effect is followed.
4, the utlity model has simple in structure, lightweight, the features such as simple, reliable performance are installed.

Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in Figure 2-5, a kind of new-type rolling bearing of the utility model grinding machine movable end support device, it comprises bearing supporting body 1 and quill shaft 2, bearing supporting body 1 and the common formation grinding machine of quill shaft 2 movable end support device.
Described bearing supporting body 1 comprises rolling bearing 11, bearing upper cover 12, bearing base 13, described rolling bearing 11 is arranged on the inside of the bearing housing of bearing upper cover 12 and bearing base 13 compositions, the rolling bearing 11 of described bearing supporting body 1 is nested with on quill shaft 2, described rolling bearing 11 is outer spherical surface aligning biserial cylindrical roller bearing, the bearing outer ring 111 of described rolling bearing is sphere, the both sides of described bearing outer ring 111 arrange rib 1111, on the bearing inner race 112 of described rolling bearing without rib, the width of described bearing inner race 112 is greater than the width of bearing outer ring 111.
Rolling bearing 11 is selected in the present embodiment is that the width of inner ring 112 is 50mm, the width of bearing outer ring 111 is the biserial cylindrical roller bearing of 30mm, conventionally rolling bearing inner ring and bearing outer ring width choice criteria are longer according to grinding machine length, and bearing inner race width is larger than bearing outer ring width.
The inside of described bearing base 13 has the inner ball surface 131 matching with the bearing outer ring of rolling bearing 11, in the present embodiment, described inner ball surface 131 diameter ranges are (1000-1600)+0.2mm, and to process with bearing fit angular range be 90-120 °, inner ball surface width is identical with the bearing outer ring width of rolling bearing, and width is arranged between 160-450mm.The bearing outer ring sphere of described rolling bearing 11 can closely cooperate to realize the aligning function for grinding machine with the inner inner ball surface arranging of bearing base 13.
The left side at the position combining with quill shaft 2 at rolling bearing 11 is provided with bearing inner race fixing device 3, described bearing inner race fixing device 3 is nested with on the circular groove 21 of offering on quill shaft 2, described bearing inner race fixing device 3 is two symmetrically arranged semicircle holding rings 31, the two ends of the circular holding ring 31 of two halves are bolted respectively and form a complete circular holding ring together, on described circular holding ring holding circular groove.
The bearing inner race 112 of described rolling bearing 11 is fixed with the circular holding ring holding that fixedly adopted of quill shaft 12, can avoid like this relatively moving on bearing inner race 112 and quill shaft 12.
Inner ball surface 131 centers of described bearing base 13 offer center oil groove 1311, in the present embodiment, and center oil well width e=20-30mm, degree of depth f=2mm.Lubricant oil can enter the gap between the inner ball surface of bearing base 13 and the bearing outer ring sphere of rolling bearing 11 by center oil groove 131 like this, to play lubricated effect.
Rolling bearing normally determines according to grinding machine specification, and grinding machine specification is larger conventionally, and rolling bearing is selected also larger.
This new device has been simplified the structure that cooperatively interacts, and has reduced fault point, eliminates safe hidden trouble, and makes grinding machine operation more reliable and more stable; Also have lightweight, the features such as simple are installed.
The above is preferred implementation of the present utility model; for those skilled in the art; not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications are also regarded as protection domain of the present utility model.
