Abstract
The utility model relates to a front/rear middle axile part assembly of a bicycle, which can reduce abrasion. The utility model is characterized in that a steel bowl and steel balls at both internal sides of an axile hub are changed into bearings; both sides of a stick axis are additionally and respectively provided with an axis sleeve; the outer sides of bearings at both sides are additionally and respectively provided with an oil seal; the axile hub is additionally provided with an oil hole; in the axile hub, the axis sleeves are arranged at both sides of the stick axis, and the bearings are arranged on the axis sleeves at both sides of the stick axis; the outer sides of bearings at both sides are provided with the oil seals; a seal cover is arranged between the axis sleeves and the axile hub so that lubricating oil injected through the oil hole can not leak, and therefore, the lubricating oil planes of the bearings are kept normal.
Description
The utility model relates to the device of a kind of bicycle front and back axis component assembly, the working life of the whole rotatable parts of axis before and after especially prolonging.
The structure of axis parts is combined by rod axle, steel bowl, steel ball, propeller boss before and after the present known bicycle, the propeller boss both sides rotate around the rod axle with steel bowl utilization steel ball, owing to run well, so will be often to its rotatable parts lubricating oil filling, must Knock-Down Component and whenever add lubricant oil, bother very much, just cause the frequent oil starvation of its rotatable parts easily, make steel bowl, steel ball wearing and tearing, propeller boss can't keep its accurate position around the rotation of rod axle like this, causes the badly damaged of whole rotatable parts.
The purpose of this utility model provides a kind of bicycle front and back axis component assembly, and it can not only prolong the working life of whole parts, and can keep bicycle laborsaving for a long time, quick.
The purpose of this utility model is to realize like this, use steel bowl, the steel ball of both sides in its parts instead bearing, the bearing outside installs oil sealing additional, and the interior external diameter of bearing enclosure equates, be coupling at bearing enclosure and rod and touch the position and load onto axle sleeve, the utilization axle sleeve is in order to reduce the wearing and tearing of rod axle.And wearing and tearing are when repairing, and only need the transposing axle sleeve and needn't change the rod axle.Place an oil hole in addition on propeller boss, conveniently inject lubricant oil in propeller boss, oil hole adapted oilhole screw is fastening, and the lubricant oil in the propeller boss is equipped with oil sealing owing to both sides, and inner lubricant oil can not leak, and normally keeps the oily plane of bearing lubrication.So just greatly reduce the mechanical wear of its rotatable parts, normally keep the light operation of bicycle.
Owing to adopted such scheme, can reduce the wearing and tearing of bicycle front and back axis component assembly, only steel bowl, steel ball in the former parts need be used instead and use the oil hole oiling on bearing, the propeller boss, the utilization oil sealing keeps the oily plane in the propeller boss to make bearing normally be in lubricating status.
Embodiment below in conjunction with accompanying drawing further specifies the utility model
Fig. 1 is the sectional drawing according to the assembly of axis parts before and after the bicycle that the utility model proposes.
1 propeller boss, 2 rod axles, 3 right bearings, 4 right oil sealing 5 right axle sleeves 6 left bearings 7 left oil sealing 8 left axle sleeves 9 oil holes 10 oilhole screws among the figure
Propeller boss in Fig. 1＜1〉in rod axle＜2 the left and right sides right axle sleeve＜5 are housed and left axle sleeve＜8, right bearing＜3 〉, left bearing＜6 be contained in right axle sleeve＜5 respectively and left axle sleeve＜8 on, right oil sealing＜4〉and left oil sealing＜7 be contained in right bearing＜3 and left bearing＜6 the outside, be sealed on right axle sleeve＜5〉left axle sleeve＜9〉and propeller boss＜1 between, on propeller boss, increase oil hole＜9 〉, oil hole＜9〉usefulness oilhole screw＜10〉fastening.
Claims (3)
1, axis component assembly before and after a kind of bicycle, in propeller boss, axle sleeve is contained in the left and right sides of rod axle, bearing, oil sealing are contained on the axle sleeve of both sides, it is characterized in that: the right and left axle sleeve upper bearing (metal) is contained in the inside, oil sealing is contained in the outside, be sealed on axle sleeve and propeller boss with, increase an oil hole on the propeller boss.
