Abstract
The utility model provides a ball bearing for a motorcycle hub, belonging to a structure of a non-standard rolling bearing in mechanical elements. The utility model is especially applied to aluminum alloy hubs of front and back wheels of the motorcycle, and comprises an outer ring (1), an inner ring (2) and a steel ball (3). The utility model is characterized in that a set of double-ditch ball bearings full of balls is composed and have very high bearing capacity. The utility model has the advantages that fitting width of the bearing outer ring and an inner hole of the aluminum alloy hub is enlarged; the service lives of the aluminum alloy hub and the bearings are enhanced; assembly and maintenance are convenient. The utility model is particularly applied to the motorcycle with high requirements to cross-country performance, and according to design requirement of the motorcycle, the other variant model of the utility model which is a double-ditch ball bearing with a holder can be adopted.
Description
The utility model relates to the structure of non-standard rolling bearing in the mechanical component, and it is specifically applied in the wheel hub of motorcycle front and back wheel.
At present, Figure 1 shows that the longitudinal sectional drawing of the bearing combination in the known motorcycle front and back wheel wheel hub.It is made up of the deep groove ball bearing and the abutment sleeve of two cover standards.Be drive fit between bearing outer ring and the aluminium alloy wheel hub (5), between wheel shaft (7) and the inner ring endoporus for being slidingly matched.This bearing composite structure exists several defectives.The one, the fitting surface width between bearing outer ring and the aluminium alloy wheel hub (5) is less, at motorcycle driving after a period of time, especially under the road conditions condition of crankcase ventilaton, in this cooperation and between can produce wriggling, thereby have influence on the working life of aluminium alloy wheel hub, the aluminium alloy wheel hub endoporus is enlarged and loosening the inefficacy.The 2nd, it is convenient inadequately that this bearing pack is combined in the assembling of bike wheel and the maintenance.The 3rd, the standard deep groove ball bearing all uses retainer, and is not too suitable for the motorcycle vehicle that off-the-road requirements is high though surface friction drag is less, and bearing is easy to damage.
The purpose of this utility model provides a kind of ball bearing of special use, and it can improve the working life of Motorcycle Aluminum Alloy wheel hub and bearing, the convenience degree of improving the motorcycle assembling and keeping in repair, and looks after the requirement of different motorcycle vehicles to bearing in design.
The purpose of this utility model is achieved in that the longitudinal sectional drawing that is illustrated in figure 2 as the design.It is a kind of ball bearing of hub of motorcycle special use, it is made up of outer ring (1), inner ring (2) and steel ball (3), it is characterized by: the parallel raceway groove of two circles is arranged on the endoporus of outer ring, the parallel raceway groove of two circles is arranged on the cylindrical of inner ring, distance in the outer ring between two raceway grooves equals the distance between two raceway grooves on the inner ring cylindrical, fills steel ball in outer ring raceway and the formed annular space of bear inner ring grooved railway.Adorn the ball situation as shown in Figure 4, Fig. 4 is the A-A sectional drawing of Fig. 2.
Such design has constituted the special-purpose full ball ball bearing of two ditches of a cover.Its outer ring is to have increased greatly with the width that cooperates between the aluminium alloy wheel hub (5) than above-mentioned known bearing structure, and making has bigger combination force between outer ring and the aluminium alloy wheel hub, and wriggling is difficult for producing relatively, thus the working life of having improved aluminium alloy wheel hub.This is even more important for the cast-in-block aluminum-alloy wheel.
The bearing combination that the design is integration, the best play of bearing are guaranteed in the mill, are difficult for exerting an influence in assembling and maintenance process, thereby make the assembling of bearing and maintenance work more convenient.
The design's major programme has adopted the full ball ball bearing without retainer, and this has improved the bearing capacity of bearing greatly, and especially the bearing capacity of dead load more can withstand shock be loaded it.This motorcycle on crankcase ventilaton that just is specially adapted to travel.More than integrate the working life of just having improved bearing.
All there is dress segment door at the two ends of its outer ring and inner ring in the design's bearing.In order to prevent that dust from invading and lubricating grease runs off, dust cover or seal ring are arranged at the two ends of bearing.
According to the designing requirement of different motorcycle vehicles, also can select another kind of modification ball bearing as shown in Figure 3 for use, it is characterized in that: between steel ball and steel ball, have retainer (4) to separate.It is applicable to the light motorcycle that travels when condition of road surface is better.
Owing to adopted the design's special-purpose ball bearing, improved the assembling of the working life of motorcycle front and back wheel aluminium alloy wheel hub, the durability that has increased it, bearing and the maintenance store oil amount that has been improved, has increased lubricating grease working life more convenient, bearing, and can be applicable to of the requirement of the motorcycle of different automobile types bearing.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the longitudinal sectional drawing of the bearing combination of known technology.
Fig. 2 is the longitudinal sectional drawing of special-purpose ball bearing of the present utility model.
Fig. 3 is the longitudinal sectional drawing of another modification ball bearing of the utility model.
Fig. 4 is that the A-A of Fig. 2 cuts open and schemes.
1. outer rings, 2. inner rings, 3. steel balls, 4. retainers, 5. aluminium alloy wheel hubs, 6. circlips, 7. wheel shafts among the figure
In the embodiment shown in Figure 2, formed the two ditch ball bearings of a cover by outer ring (1), inner ring (2) and steel ball (3), its full spherical structure as shown in Figure 4.The cylindrical of outer ring is with the width of its broad and the endoporus close-fitting of Motorcycle Aluminum Alloy wheel hub (5), and flexible back-up ring (6) is as preventing the usefulness that bearing moves axially in addition.The wheel shaft of front and back wheel (7) and inner ring endoporus are sliding fits, after the braking device of front and back wheel, sleeve and sprocket driving device etc. are loaded onto wheel shaft, make axial compression with the end thread of wheel shaft and nut etc.
Claims (2)
1, the ball bearing used of a kind of hub of motorcycle, it is made up of outer ring (1), inner ring (2) and steel ball (3), it is characterized by: the parallel raceway groove of two circles is arranged on the endoporus of outer ring, the parallel raceway groove of two circles is arranged on the cylindrical of inner ring, distance in the outer ring between two raceway grooves equals the distance between two raceway grooves on the inner ring cylindrical, fills steel ball in outer ring raceway and the formed annular space of bear inner ring grooved railway.
2, according to the described ball bearing of claim 1, it is characterized by: between steel ball and steel ball, have retainer (4) to separate.
