Abstract
A kind of bearing clearance mounting and adjusting structure, belongs to technical field of wind power generation.Comprise main shaft, bearing, bearing gland and bearing support, be provided with between described bearing gland and bearing and transmit the hold-down ring that bearing bears axial force, bearing gland is provided with hold-down bolt, and described hold-down bolt end contacts with bearing hold-down ring end face.The utility model transmits by arranging between bearing gland and bearing the hold-down ring that bearing bears axial force, and adopts its hold-down bolt to carry out regulating its pretightening force, can ensure bearing axial play.
Description
Technical field
The invention belongs to bearing mounting technique field, particularly relate to a kind of bearing clearance mounting and adjusting structure.
Background technique
In the drive mechanism adopting double-row conical bearing to support, the performance of installation axial internal clearance to bearing and whole Transmitted chains of bearing all has a significant impact, if when the installation play in using and the installation play designed differ more, Transmitted chains will be caused unstable.As shown in Figure 2, after the design height H of double-row conical bearing 15 determines, a tolerance range can be provided, upper deviation t1mm, lower deviation t2mm, calculate by above data, actual produced double-row conical bearing height is between (H-t2) ~ (H+t1) mm, equally, the seam 16 of the bearing saddle bore degree of depth 17 and bearing gland highly in a practical situation all can in some tolerance range, in order in an installation bearing clearance be controlled within scope of design, usual needs are according to actual bearing width, whether the actual height calculation bearing play of bearing support actual grade and bearing gland seam is pressed in scope of design.If the bearing after installing does not compress as calculated, need to increase spacer at seam 16 end face of bearing gland and come adjusting play; If if the actual gap after installing same is negative value, can ensure that bearing is compacted like this, but at this moment bearing gland and bearing support fitting surface do not compress completely like this, the bolt of linking axes bearing and gland will be operated in the operating mode of a composite force, will have a negative impact to bolt strength and life-span.In order to bearing is pressed to design play, do not affect the installation of bearing gland and chain connecting bolt simultaneously, following structure is proposed, by this structure can omit for different assembly chaining make separately spacer adjust bearing assemble gap method reach and compress the object of bearing.
Summary of the invention
For the technical problem of above-mentioned existence, the invention provides a kind of bearing clearance mounting and adjusting structure.
The object of the invention is to be achieved through the following technical solutions:
The present invention includes main shaft, bearing, bearing gland and bearing support, it is characterized in that: be provided with between described bearing gland and bearing and transmit the hold-down ring that bearing bears axial force, bearing gland is provided with hold-down bolt, and described hold-down bolt end contacts with bearing hold-down ring end face.
Further, the left half axle of described bearing holds inner ring and right axle shaft and holds between inner ring and arrange bearing space ring.
Further, described bearing support, be provided with left seal arrangement between bearing gland and hold-down ring.
Further, right seal arrangement is provided with between described bearing support and main shaft.
Further, described main shaft has the bearing lubrication oilhole communicated with bearing.
Beneficial effect of the present invention is:
The present invention transmits by arranging between bearing gland and bearing the hold-down ring that bearing bears axial force, and adopts its hold-down bolt to carry out regulating its pretightening force, can ensure bearing axial play.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present invention.
Fig. 2 is existing structure schematic diagram.
In figure: 1. main shaft, 2. bearing gland, 3. clamping bolt, 4. hold-down ring, 5. hold-down bolt, 6. left seal arrangement, 7. outer ring fixing bolt, 8. right seal arrangement, 9. bearing support (axis hole coordinated with bearing outer ring), 10. bearing outer ring, 11. left half axles hold inner ring, 12. bearing space rings, 13. right axle shafts hold inner ring, 14. bearing lubrication oilholes, 15. double-row conical bearings, 16. bearing gland seams, the 17. bearing saddle bore degree of depth.
Embodiment
Below by embodiment and accompanying drawing, the invention will be further described.
Embodiment: the present invention includes main shaft 1, bearing, bearing gland 2, bearing support 9, described main shaft 1 coordinates with brearing bore, and bearing support 9 coordinates with bearing outer ring 10, is fixed by outer ring fixing bolt 7; Be provided with between described bearing gland 2 and bearing and transmit the hold-down ring 4 that bearing bears axial force, bearing gland 2 is provided with hold-down bolt 5, and described hold-down bolt 5 end contacts with bearing hold-down ring 4 end face.Described bearing is double-row conical bearing.
The left half axle of described bearing holds inner ring 11 and right axle shaft and holds between inner ring 13 and arrange bearing space ring 12, spacer ring also has and is called back-up ring, spacer ring etc., belonging to the conventional structure of double-row conical bearing, is also the structure needs of this bearing while that its effect being adjustment bearing clearance.
Described bearing support 9, between bearing gland 2 and hold-down ring 4, be provided with left seal arrangement 6.Right seal arrangement 8 is provided with between described bearing support 9 and main shaft 1.Described left seal arrangement 6 and right seal arrangement 8 are conventional prior art, are the sealings of the bearing left and right sides, can adopt various ways, and what this example adopted is reinforced seal.
Described main shaft 1 has the bearing lubrication oilhole 14 communicated with bearing, with lubricating bearings.
The present invention is when bearing working, the end thrust Fx that bearing bears, will be delivered to bearing from the main shaft 1 on right side, and by right axle shaft hold inner ring 13, bearing space ring 12, left half axle hold inner ring 11 and be delivered on the bearing hold-down ring 4 in left side, and passes to bearing gland 2 and clamping bolt 3 by the hold-down bolt 5 of bearing hold-down ring 4.The thrust that the hold-down bolt 5 of bearing hold-down ring 12 can bear need meet the pretightening force requirement of design bearing, and the maximum axial thrust Fx (comprising safety coefficient) produced when being greater than bearing working, so just, by the hold-down bolt 5 of pretension hold-down ring 4, the object of bearing axial play can be ensured.
