According to the rapid play adjusting structure provided by the utility model, the axial play between the two bearings is ensured by controlling the size between mounting faces of the outer rings of the two bearings of the bearing base and the tolerance of the size and controlling the axial tolerance of the partition ring between the two bearings; a play of the bearing is ensured to be within an ideal range; the service life of the bearing is long; no special requirement on skills of an assembling worker exists; special equipment does not need to be invested; the quality uniformity is good; and the efficiency is high.
Description
Technical field
The utility model relates to bearing clearance adjustment technology field, is specifically related to a kind of bearing clearance rapid adjustment structure that can the rapid adjustment bearing clearance.
Background technique
Problems such as in fields such as machinery, electromechanics, bearing is widely used, and bearing clearance is most important to guaranteeing bearing proper functioning and expected service life, and right existing bearing play adjustment structure exists adjustment complicated, and effect is undesirable.
Fig. 1 is a kind of typical structure of existing technology middle (center) bearing play adjustment; Two tapered roller bearings 101 of symmetric arrangement and 103 on the drive bevel gear 104 of automobile drive axle main reducing gear; Bearing outer ring is fitted on the bearing support 102 in advance, and bearing clearance is guaranteed by the spacer ring between the two bearings inner ring 105, adjustment pad 106 and 107.The adjustment pad choose branch artificial with two kinds in machine, the main dependence of artificial choosing pad rigger's personal experience, conformity of production is poor, directly causes the bearing life discreteness big.Machine selects the pad process complicated, and equipment has high input: the technology pad of packing into earlier between the two bearings inner ring, then according to the machine measured value, pull down bearing again, and the adjustment pad of the specific thicknesses of packing into is loaded onto bearing again.Different according to thickness, generally need to prepare 20～30 kinds of adjustment pads.
Summary of the invention
In sum, in order to overcome the deficiency of existing technology problem, the utility model provides a kind of bearing clearance rapid adjustment structure; It is to guarantee two axial internal clearancies between the bearing through the tolerance of dimension D between the attachment face of strict Control Shaft bearing two bearings outer ring and the strict axial tolerance of controlling the spacer ring between two bearings, only needs during use spacer ring is installed between two bearing inner races, tightens main flare nut then and gets final product; Guarantee that bearing clearance is in ideal range; Bearing life is long, and rigger's technical ability is not had specific (special) requirements, need not to drop into special device; Quality conformance is good, and efficient is high.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of bearing clearance rapid adjustment structure; Wherein: it comprises bearing support, upper bearing (metal), lower bearing, spacer ring and main flare nut; The outer ring of upper bearing (metal) and the outer ring of lower bearing are fitted in the bearing support; The bearing support inwall is provided with inside convexity; Protruding axial dimension equals the installation dimension between the outer ring of outer ring and lower bearing of upper bearing (metal), and snag axis equals the tolerance clearance of installation requirement of outer ring of outer ring and the lower bearing of upper bearing (metal) to tolerance of size, be provided with spacer ring between the inner ring of upper bearing (metal) and the inner ring of lower bearing; The spacer ring axial dimension equals the assemblage gap size between the inner ring of inner ring and lower bearing of upper bearing (metal), and the inner ring of upper bearing (metal) and lower bearing inner ring compress through main flare nut.
Further, the actual screw-down torque of described main flare nut equates with Bearing Installation regulation moment.
The beneficial effect of the utility model is:
1, the utility model is to guarantee two axial internal clearancies between the bearing through the tolerance of dimension D between the attachment face of strict Control Shaft bearing two bearings outer ring and the axial tolerance of the spacer ring between two bearings of strict control, only needs during use spacer ring is installed between two bearing inner races, tightens main flare nut then and gets final product; Guarantee that bearing clearance is in ideal range; Bearing life is long, and rigger's technical ability is not had specific (special) requirements, need not to drop into special device; Quality conformance is good, and efficient is high.
2, the utility model is simple in structure, installation is easy, and applied range in the equipment applicable to the adjustment of various bearing playes, can guarantee effectively that bearing clearance is in ideal range.
