Abstract

The utility model provides a novel wheel hub bearing includes bearing inner race, bearing inner race, holder, ball, interior dust ring and outer dust ring, bearing inner race install the inside at bearing inner race, the ball install between bearing inner race and bearing inner race, the holder even spaced apart with the ball, interior dust ring pass through interference fit and install the left and right sides at bearing inner race, outer dust ring pass through interference fit and install the left and right sides at bearing inner race. The utility model discloses a setting of interior dust ring and outer dust ring, each part frictional force within a definite time is less, and the bearing rotates in a flexible way, does not have the card and pauses, is favorable to the reduce friction resistance, reduces manufacturing cost, through to the control of bearing inner race with bearing inner race axial internal clearance, be favorable to guaranteeing the precision after the part dispatches from the factory, the life of extension part.

Description

A kind of new hub bearing

Technical field

This utility model belongs to technical field of bearings, more particularly, to a kind of new hub bearing.

Background technology

With the high speed development of automobile industry and its supporting industries concerned, each manufacturer and user are to car load or parts The quality of product is also proposed higher requirement, and current automobile hub bearing is to be carried out dust-proof using dust cap, and structure compares Single, sealing can be poor, and external impurities easily enter Bearing inner thus causing the damage of bearing, plays obstruction work to the lubrication of bearing With thus reducing bearing service life, the bearing decomposition cleaning frequency is short, improves customer using cost；Sealing property simultaneously Bad, the grease of Bearing inner or lubricating oil easily leak outside, and grease consumption is big, and impact working environment is clean, increases axle The use cost held, prior art is that the hub bearing that patent announcement number is CN203395008U employed technical scheme comprise that：Bag Include outer ring, inner ring, two sealing inserts, two retainers and two row tapered rollers, also include connection ring, described inner ring is Pyramidal structure, inner ring small end face is provided with conflict end, and this inner ring is provided with the conflict end groove, described inner ring be two and Two inner rings make two conflict ends offset by connection ring, and described connection ring is arched, and described connection ring both sides are respectively Clasp described groove；Described inner ring is provided with hypotenuse step with respect to the other end at conflict end, described outer ring two ends interior Wall is provided with Baltimore groove, is provided with sealing inserts at this Baltimore groove, and this sealing inserts inner edge fits in inner ring hypotenuse step, has anti- The good advantage of dirt effect.But, existing hub bearing has that frictional resistance is big, complex structure, manufacturing cost are high, use the longevity Order short problem.

Therefore, invent a kind of new hub bearing and seem very necessary.

Utility model content

This utility model is that present in solution known technology, frictional resistance is big, complex structure, manufacturing cost are high, uses the longevity Order short problem and a kind of new hub bearing is provided.

This utility model is adopted the technical scheme that by solving technical problem present in known technology：A kind of new Hub bearing includes bearing outer ring, bearing inner race, retainer, ball, interior dust ring and outer dust ring, and described bearing inner race is pacified It is contained in the inside of bearing outer ring, described ball is arranged between bearing outer ring and bearing inner race, described retainer is by ball Uniformly it is spaced apart.

This utility model can also adopt following technical measures.

Described interior dust ring is arranged on the left and right sides of bearing inner race by interference fit, and described outer dust ring passes through Interference fit is arranged on the left and right sides of bearing outer ring.

Grease is scribbled, described interior dust ring and outer dust ring constitute song between described interior dust ring and outer dust ring Road seals, and has good sealing effect, the simple advantage of structure, due to there is gap between interior dust ring and outer dust ring, so Frictional force between each part is less, and bearing rotates flexibly, no interim card, is conducive to reducing frictional resistance, reduces manufacturing cost.

Described bearing inner race is less than or equal to 0.006mm with the difference in internal diameters of bearing inner race.

The end-play of described bearing outer ring and bearing inner race is arranged between 0.05mm to 0.07mm, advantageously ensures that Part dispatch from the factory after precision, extend part service life.

This utility model has the advantages and positive effects that：

, by the setting of interior dust ring and outer dust ring, the frictional force between each part is less for this utility model, and bearing rotates Flexibly, no interim card, is conducive to reducing frictional resistance, reduces manufacturing cost；By to bearing outer ring and bearing inner race end-play Control, advantageously ensure that part dispatch from the factory after precision, extend part service life.

Brief description

Fig. 1 is structural representation of the present utility model.

In figure：

1- bearing outer ring, 2- bearing inner race, 3- retainer, 4- ball, dust ring in 5-, the outer dust ring of 6-.

Specific embodiment

Below in conjunction with accompanying drawing, this utility model is described further：

Embodiment：

As shown in Figure 1

This utility model provides a kind of new hub bearing to include bearing outer ring 1, bearing inner race 2, retainer 3, ball 4th, interior dust ring 5 and outer dust ring 6, described bearing inner race 2 is arranged on the inside of bearing outer ring 1, and described ball 4 is arranged on Between bearing outer ring 1 and bearing inner race 2, ball 4 is uniformly spaced apart by described retainer 3.

This utility model can also adopt following technical measures.

Described interior dust ring 5 is arranged on the left and right sides of bearing inner race 2 by interference fit, described outer dust ring 6 It is arranged on the left and right sides of bearing outer ring 1 by interference fit.

Grease, described interior dust ring 5 and outer dust ring 6 structure is scribbled between described interior dust ring 5 and outer dust ring 6 Become labyrinth seal, there is good sealing effect, the simple advantage of structure, between existing between interior dust ring 5 and outer dust ring 6 Gap, so the frictional force between each part is less, bearing rotates flexibly, no interim card, is conducive to reduction frictional resistance, reduction to be manufactured into This.

Described bearing inner race 2 is less than or equal to 0.006mm with the difference in internal diameters of bearing inner race 2.

The end-play of described bearing outer ring 1 and bearing inner race 2 is arranged between 0.05mm to 0.07mm, is conducive to protecting Demonstrate,prove the precision after part dispatches from the factory, the service life of prolongation part.

Operation principle

This utility model in use, constitutes labyrinth seal by interior dust ring and outer dust ring, grease will not Spilling, dust and the grains of sand are blocked in the outside of outer dust ring, using hydraulic press, part are loaded wheel hub when mounted.
