Abstract
The utility model relates to a novel pedal bearing of a bicycle, which replaces the pedal bearing of the existing bicycle and comprises a pedal axis, an axis sleeve, a pedal sleeve tube, a cushion ring and a retainer ring. The axis and the axis sleeve is in slip fit; the axial position of the utility model is obtained by the retainer ring or a pin on the end of the axis. The utility model has the advantages of convenient installation and maintenance, ideal effect, easy processing, low cost, long service life, etc.
Description
The utility model relates to a kind of bicycle pedal bearing.
In the prior art, bicycle pedal all adopts traditional rolling bearing, it is made of with locking plate and nut location pedal axle, pedal sleeve pipe, axle bowl, axle shelves, steel ball and outer end, this class bearing in use steel ball be easy to produce abrasion, spot corrosion with axle shelves, axle bowl, squeeze broken, situations such as distortion, and make whole pedal parts damage and scrap.In addition, the rolling bearing processed complex of this pedal, the cost height is being installed, and adjusts, and is also very inconvenient during repairing, therefore influences the working life of whole pedal parts.
The purpose of this utility model is with a kind of novel bicycle pedal bearing, replaces existing bicycle pedal bearing, thereby provides a kind of installation, repairing conveniently, and processing is simple, and is with low cost, the bicycle pedal bearing of long service life.
The utility model is made of pedal axle, axle sleeve, pedal sleeve pipe, packing ring and ring washer or pin, and described main points are axle sleeve to be entrenched in two ends of pedal sleeve pipe, and is inserted in the pedal axle and is slidingly matched with axle, and its axially locating realizes by the ring washer or the pin of axle outer end.
Accompanying drawings:
Fig. 1 is the sectional view of bicycle pedal bearing, and it is made of pedal axle (1), axle sleeve (4), axle sleeve (5), pedal sleeve pipe (6), packing ring (3) and ring washer (2).Axle sleeve (4), axle sleeve (5) are two ends that are entrenched in pedal sleeve pipe (6), and be inserted in pedal axle (1) with the axle be slidingly matched, its axially locating realizes by the ring washer (2) or the pin of axle outer end, between axle sleeve (4) and ring washer (2), a packing ring (3) is arranged, between packing ring (3) and the ring washer (2) certain clearance is arranged, make pedal axle (1) in axle sleeve hole, can rotate flexibly.Pedal axle (1) is to be stepped shaft, and an end is big, an end is little, holds machining screw to be used for connecting crank greatly, and circular orientation groove of small end top processing or positioning hole are used to install ring washer (2) or pin.Axle sleeve is made with plastics or nylon injection-molding, have high wear resistance and low coefficient of friction, the one end is a coaxial clyinder, and the other end is circular method indigo plant, the circular outer rim chamfering of method indigo plant and tapered, its center is a manhole, the internal diameter of axle sleeve (4) is 6～8 millimeters, and with 3～4 millimeters of axle friction portion wall thickness, the internal diameter of axle sleeve (5) is 8～11 millimeters, with 1.5～3 millimeters of axle friction portion wall thickness, their length is 5～15 millimeters.The pedal sleeve pipe (6) of pedal is than long 5～15 millimeters of the pedal sleeve pipe that has specification pedal of the same type now.Ring washer (2) is to be shaped with elastomeric iron sheet punching out, and packing ring (3) forms with the sheet iron punching out.
Installation step of the present utility model is as follows: axle sleeve (4), axle sleeve (5) are entrenched in two ends of pedal sleeve pipe (6), are inserted in pedal axle (1) and are slidingly matched, be inserted in packing ring (3) at axle head again with axle, and install a slice ring washer (2) be used for positioning instant can.
Above-described bottom bracket bearing parts, its axle sleeve can be made with small-sized injection machine injection moulding, pedal axle (1), pedal sleeve pipe (6) improve a little on the manufacturing mechanism of existing bicycle pedal industry and can manufacture, and packing ring (3) and ring washer (2) form with small-sized punch press punching out.
The utility model is installed simple, low, the long service life of cost, and the pedal of suitable other vehicle.
Claims (4)
1, a kind of bicycle pedal bearing, comprise pedal axle (1), pedal sleeve pipe (6), it is characterized in that axle sleeve (4), axle sleeve (5) are entrenched in two ends of pedal sleeve pipe (6), and be inserted in pedal axle (1) with the axle be slidingly matched, its axially locating realizes by the ring washer (2) or the pin of axle outer end, between axle sleeve (4) and ring washer (2), a packing ring (3) is arranged, between packing ring (3) and the ring washer (2) certain clearance is arranged, make pedal axle (1) in axle sleeve hole, can rotate flexibly, thereby constitute a kind of bottom bracket bearing of bicycle.
