Abstract
The utility model relates to a bearing for a bicycle, which comprises an outer ring, an inner ring, a seal ring, a retainer and a rolling element arranged on the retainer, wherein the outer ring is provided with a step, and the outer edge of the step is provided with a chamfer; and the inner edge of the inner ring is also provided with a chamfer. Due to the specific shape of the outer ring, the bearing can be directly arranged on an axle of the bicycle, therefore, the installation and replacement are more convenient and simple, the reliability is higher, and the bearing better meets the requirement of high-level bicycles and electric bicycles.
Description
(1) technical field
The utility model relates to a kind of bearing, especially is applied in the bearing on the bicycle.
(2) background technique
Along with the generation of economic crisis and rising violently of gas price, bicycle becomes the optimal selection of popular trip.And along with the expansion in bicycle market, it is fierce more that competition also becoming.Quality is lighter, and intensity is higher, and the higher bicycle of Security becomes first-selection.Existing traditional bicycle use ball bearing mostly is an angular contact ball bearing, and material is generally high-carbon and presses against steel GCr15 density 〉=7.87g/cm3 and stainless steel 9Cr18, density 〉=7.75g/cm3.The bicycle quality is big, intensity is not high, and angular contact ball bearing installs comparatively trouble, need be connected the bearing specific workpiece of packing on the axle for bicycle again.
(3) summary of the invention
In order to overcome the deficiency of changing trouble is installed in the prior art, it is convenient simple and direct that the utility model provides a kind of installation to change, and fastness is stronger, and quality is lighter, the bicycle use bearing that safety coefficient is higher.
The technical scheme in the invention for solving the technical problem is:
A kind of bicycle use bearing comprises outer collar, inside race, seal ring, retainer and is located at rolling element on the retainer that described outer collar is provided with ladder, and the outer edge place of ladder is provided with chamfering.
Chamfering is set to 15 °, and the given shape of outer collar makes bearing can be directly installed on the axle for bicycle, and installation is changed convenient simple and direct, and fastness is stronger, is fit to the high-grade bicycle and the requirement of electric bicycle more.
As improvement, the inner ring edge of inside race is provided with chamfering.Chamfering is set to 45 °, and axial bearing capacity is bigger.
As preferably, inside race and outer collar are titanium alloy.Material is TC4, and density is 4.44g/cm3, and relative traditional material high-carbon presses against steel GCr15 and stainless steel 9Cr18 is more corrosion-resistant, and anti-oxidant, thermostability is better, and intensity is higher, and nonmagnetic, and croop property and fracture toughness are better.
As preferably, rolling element is a ceramic ball.Inner rolling element be Si3N4 silicon nitride ceramic ball light weight, high temperature resistant, intensity is high.
The beneficial effects of the utility model are: the utility model is provided with ladder with bearing outside collar, and the outer edge place of ladder is provided with chamfering, then axial bearing capacity is bigger, bearing can be directly installed on the axle for bicycle, it is convenient simple and direct that replacing is installed, fastness is stronger, is fit to the high-grade bicycle and the requirement of electric bicycle more.
(4) description of drawings
Fig. 1 is the utility model structural representation.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
A kind of bicycle use bearing can be directly installed on the axle for bicycle, comprises outer collar 5, inside race 2, seal ring 1, retainer 4 and is located at rolling element 3 on the retainer.Outer collar is provided with ladder, and the outer edge place of ladder is provided with 15 ° of chamferings, and the inner ring edge of inside race also is provided with 45 ° of chamferings, and inside race and outer collar material are titanium alloy TC 4, and density is 4.44g/cm3.Inner rolling element 3 is the Si3N4 silicon nitride ceramic ball, and retainer 4 is a bowl type entity project plastic nylon retainer, and the satisfactory while quality of intensity is lighter, quiet better effects if.Seal ring is the skeleton rubber seal ring, good sealing effect.
Claims (4)
1. bicycle use bearing comprises outer collar, inside race, seal ring, retainer and is located at rolling element on the retainer that it is characterized in that: described outer collar is provided with ladder, and the outer edge place of ladder is provided with chamfering.
2. bicycle use bearing according to claim 1 is characterized in that: the inner ring edge of described inside race is provided with chamfering.
