Abstract
The utility model discloses a big inner circle of automobile wheel hub bearing offers the splined hole at the center of big inner circle body, and an organic whole is formed with the ring flange on the outer circumference of big inner circle body, its characterized in that: an organic whole is formed with a plurality of deep floor that press circumference evenly distributed's flange shape on the ring flange, has all seted up the installation screw on each deep floor, and the installation screw runs through the quotation of ring flange, the edge of ring flange is opened has a plurality of stress breachs that unload, and the figure that unloads the stress breach is equal with deep floor's figure to unload stress breach and deep floor interval and set up, unload the distance that makes progress between the double -phase adjacent deep floor in stress breach and week and equal. The utility model relates to an ingenious, simple structure, transformation be easy, it is with low costs to reform transform, under the requirement of satisfying load, intensity, can effectively reduce the ring flange end and jump to alleviate bearing assembly weight, accorded with the requirement of product lightweight design.
Description
Technical field
The utility model belongs to technical field of bearings, specifically, and particularly a kind of large inner ring of automobile hub bearing.
Background technique
Automobile hub bearing is the important component part in automobile runs, and can the working order of wheel directly decides automobile smooth-ride.Present stage, along with user vehicle is for the requirement of car load travelling comfort, for hub bearing product aspect, property indices requires more and more stricter.Wherein the beating of wheel hub product and brake disc mounting flange face, if product end is skipped greatly, can cause in wheel operation process and occur the phenomenon such as side-sway, violent shake, have a strong impact on the travelling comfort of car load, thus become current client carry out brake assembly assembling time, emphasis detect project.At present, domestic existing three generations's hub bearing product, flange plate end face run-out is generally adopted and is ensured that finished product section is beated in two ways: one is that thickening flange plate dish is thick, and two is increase finished product finish turning flange surface.But present process program, product weightening finish is comparatively large on the one hand, with product future development---lightweight is not inconsistent, on the other hand, increases finished product finish turning operation larger for product cost increase.
Model utility content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model be to provide a kind of can weight reduction, reduce the large inner ring of automobile hub bearing that end jumps.
Technical solutions of the utility model are as follows: the large inner ring of a kind of automobile hub bearing, there is large inner ring body, splined hole is offered at the center of large inner ring body, the excircle of large inner ring body is formed with flange plate, it is characterized in that: the reinforcement gusset being formed with multiple circumferentially equally distributed flange shape on described flange plate, each reinforcement gusset all offers installation screw, and installation screw runs through the card of flange plate; Have at the edge of described flange plate and multiplely unload stress breach, the number unloading stress breach is equal with the number strengthening gusset, and unloads stress breach and strengthen gusset interval and arrange, and unloads stress breach equal with the adjacent distance strengthened between gusset of two-phase in circumference.
Adopt above technological scheme, large inner ring flange remodeling is become stiffening rib plate structure, ensure that hub bearing press-fits wheel bolt part position and has enough intensity, effectively prevent hub bearing because of flange plate insufficient strength and occur failure phenomenon, meanwhile, the requirement of product light-weight design is met; Open several breach at large inner ring flange surface edge, the stress deformation that hub bearing occurs due to pressure bolt can be shed, not only alleviate the weight of hub bearing, and solve flange plate end and skip large problem.
Conveniently processing and fabricating, makes reduction end jump more remarkable effect, described in unload stress breach be circular arc.
As preferably, described large inner ring body is made up of 65 manganese steel.
Beneficial effect: the utility model design is ingenious, structure simple, transformation easy, reforming cost is low, under the requirement meeting load, intensity, effectively can reduce flange plate end and jump, and alleviate bearing assembly weight, meet the requirement of product light-weight design.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the side view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, the large inner ring of automobile hub bearing has large inner ring body 1, and this large inner ring body 1 is made up of 65 manganese steel.Offer splined hole 11 at the center of large inner ring body 1, the excircle of large inner ring body 1 is formed with flange plate 12.Flange plate 12 is formed with the reinforcement gusset 13 of multiple circumferentially equally distributed flange shape, and the number strengthening gusset 13 is determined according to actual needs, and the present embodiment is preferably 5, and these 5 reinforcement gussets 13 are in the same plane.Each reinforcement gusset 13 all offers installation screw 14, and installation screw 14 runs through the card of flange plate 12.Have at the edge of flange plate 12 and multiplely unload stress breach 15, unload stress breach 15 and be preferably circular arc.The number unloading stress breach 15 is equal with the number strengthening gusset 13, and unloads stress breach 15 and strengthen the setting of gusset 13 interval, unloads stress breach 15 equal with the distance that two-phase neighbour in circumference strengthens between gusset 13.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
