Abstract
The invention discloses a driving shaft assembly with a support structure. The driving shaft assembly comprises a support body 1 and a bearing retainer ring clamp spring assembly 2, a bearing outer ring 21 of the bearing retainer ring clamp spring assembly 2 is installed in a support inner ring 11 of the support body 1, and the bearing outer ring 21 is in clearance fit with the support inner ring 11. The driving shaft assembly is characterized in that a threaded through hole is formed in the radial direction of the support body 1, a rubber plug 3 is installed in the threaded through hole, an end portion 32 of the rubber plug presses the bearing outer ring 21 tightly, a bolt 4 is screwed into the threaded through hole, the rubber plug 3 is pressed tightly, the pressing force to the bearing outer ring is generated through compression of the rubber plug 3, and therefore the matched tightness degree between the bearing outer ring 21 and the support inner ring 11 is adjusted so as to achieve the purposes of vibration reducing and mode optimization. The driving shaft assembly has the advantages of being simple in structure, convenient to operate, high in practicability and the like.
Description
Technical field
The invention belongs to automobile component, be specifically related to the drive shaft assembly structure of automobile.
Background technology
The drive shaft assembly of belt supporting frame structure on automobile, does not connect on general run of thins lower bracket or supporting driving shaft parts is in addition set at present, and referring to Fig. 1, its structure comprises rack body 1, end ring and clamp spring component 2.In this structure, the outside race 21 of end ring and clamp spring component 2 is generally with the very little free-running fit in gap with the support inner ring 11 of rack body 1.When outside race dimension limit is walked allowance below nominal size, support inner ring dimension limit is gone on when poor, outside race 21 is maximum with the tolerance clearance of support inner ring 11, now coordinate and there will be slight looseness, bearing is in the process of High Rotation Speed, and it is optimum that the vibration of axle drive shaft and model frequency cannot reach, and cannot regulate, if improved, can only change the bracket assembly that tolerance grade is higher, thereby cause waste.
Summary of the invention
The deficiency existing for prior art, the invention provides a kind of drive shaft assembly of belt supporting frame structure, make it by adjusting pre-tightening mechanism, reach the tightness degree that coordinates of adjusting shaft bearing outer-ring and support inner ring, thereby reduce bear vibration, regulate mode, optimize the NVH performance of axle drive shaft.
Technical scheme of the present invention is as follows:
A drive shaft assembly for belt supporting frame structure, comprises rack body and end ring clamp spring component, and the outside race of end ring clamp spring component is arranged in the support inner ring of rack body, both free-running fits.Improvement of the present invention is: on rack body, be radially provided with tapped through hole, glue is housed in tapped through hole stifled, the end compression axis bearing outer-ring that glue is stifled, bolt is screwed in tapped bore, compression glue is stifled, by glue, block up compression and produce the thrust to outside race, thus the tightness degree that coordinates of adjusting shaft bearing outer-ring and rack body inner ring.
Further, described bolt is hollow bolt, and the afterbody that glue is stifled and the groove of hollow bolt pass through interference fit.Described rack body has boss tapped through hole position is set, and tapped through hole is processed on boss.
The present invention by arranging pretension regulating mechanism on support, by glue, block up compression and produce the thrust to outside race, thereby the tightness degree that coordinates of adjusting shaft bearing outer-ring and rack body inner ring, to reach, reduce vibration, the object of optimizing mode, has the advantages such as simple in structure, easy to operate, practical.
Accompanying drawing explanation
Fig. 1 is background technology structural representation
Fig. 2 is structural representation of the present invention.
Fig. 3 is mounting structure schematic diagram of the present invention.
In figure, 1-rack body, 11 is that support inner ring, 12 is for boss, 13 is for tapped bore, 2-end ring clamp spring component, 21 are for outside race, 3-glue are stifled, 31 for the stifled afterbody of glue, 32 is for glue blocks up end, 4-hollow bolt, 41 is groove.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate structure of the present invention:
Referring to Fig. 2 and Fig. 3, the drive shaft assembly of belt supporting frame structure comprises rack body 1, end ring clamp spring component 2, glue stifled 3 and hollow bolt 4.When casting axle drive shaft rack body 1, by demand, cast out machinable boss 12, on boss, along rack body, radially attack the tapped through hole 13 of dimension, make the hollow bolt 4 coordinating with tapped through hole, and glue stifled 3 is arranged in the groove 41 of hollow bolt 4, the stifled afterbody 31 of glue passes through after interference fit with the groove 41 of hollow bolt 4, hollow bolt 4 is screwed in the tapped through hole 13 on boss 12, glue stifled 3 is interference fit with boss tapped bore 13, now the stifled end 32 of glue compresses the outer ring 21 of bearing, by glue, block up 3 compressions and produce the thrust to outside race, the tightness degree that coordinates of adjusting shaft bearing outer-ring 21 and rack body inner ring 11.
Claims (3)
1. a drive shaft assembly for belt supporting frame structure, comprises rack body (1) and end ring clamp spring component (2), and the outside race of end ring clamp spring component (21) is arranged in support inner ring (11), both free-running fits; It is characterized in that: on rack body (1), be radially provided with tapped through hole (13), glue stifled (3) is housed in tapped through hole, end (32) the compression axis bearing outer-ring (21) that glue is stifled, bolt (4) is screwed in tapped bore, push down glue stifled (3), by glue, block up compression and produce the thrust to outside race, thus the tightness degree that coordinates of adjusting shaft bearing outer-ring (21) and support inner ring (11).
