Abstract
The utility model relates to an antiwear aluminium alloy bicycle pedal. The utility model comprises a pedal body, a gasket and a nut which are used to position the end part of a core shaft, wherein, a pedal body is an aluminium alloy integrally shaped part, which comprises a center shaft sleeve which is sheathed with a core shaft sleeve, and both ends in the shaft sleeve are respectively provided with an oil-retaining bearing; the inner end of the bearing is in axial direction positioned by a positioning ring, the outer end of the shaft sleeve is provided with an outer protective cover, and the inner end is provided with an inner protective cover. The bicycle pedal overcomes the defects that a ball-bearing of the traditional pedal is easy to be worn, and the antiwear performance is poor. The utility model has the advantages of simple structure, convenient installation, and high durability.
Description
The utility model relates to a kind of bicycle pedals, the wear-resisting bicycle pedals of particularly a kind of aluminum alloy.
Bicycle pedals is the vitals of bicycle, also is easily worn part.Traditional bicycle pedals comprises mandrel, iron plate punching press axle sleeve, and ball bearing assembly is equipped with at the axle sleeve two ends, and both sides are equipped with rubber assembly, are connected and fixed by end plate again.This foot-operated parts are many, and the heavy and assembling trouble of benzene, and the ball in service extruding that overlaps each other easily consequently are extruded the steel bowl or come off naturally in the steel bowl, and chuck is stung easily tightly, killed, and can not normally use, and often scraps in a short time to abandon.This foot-operated being difficult to after scrapping reclaims, and causes environmental pollution.
The purpose of this utility model provides the wear-resisting bicycle pedals of a kind of aluminum alloy, and it can overcome the foot-operated above-mentioned shortcoming of standard bicycle, have simple in structure, easy to assembly, wear-resisting, long service life, and manufacturing process characteristic of simple.
The utility model bicycle pedals comprises foot-operated body and the packing ring, the nut that are used for location, mandrel end, and foot-operated body is an aluminum alloy global formation spare, and it contains the central axle sleeve with the mandrel socket, and two ends respectively are provided with a graphite oilless sintered-metal bearing in the axle sleeve; The inner of bearing is with the nest axial location, and outer protective cover is equipped with in the outer end of axle sleeve, and interior protective cover is equipped with in the inner.
The utility model bicycle pedals adopts monolithic extruded molded aluminum alloy body to replace a plurality of parts such as foot-operated iron plate punching press sleeve pipe of standard bicycle and rubber assembly, replace traditional ball bearing assembly with graphite oilless sintered-metal bearing, thereby a large amount of parts and attaching parts have been saved, structure and manufacturing process are simplified greatly, overcome the fragile and baroque shortcoming of ball bearing of main shaft, easy to assembly, and it is in light weight, specious, wear resisting property is good, and is durable in use, even scrap, the recyclable remelting of its aluminium scrap does not pollute the environment.
Below in conjunction with description of drawings example structure of the present utility model.
Fig. 1 is the wear-resisting foot-operated assembly drowing of the utility model aluminum alloy.
Fig. 2 is axle and tail end fastening assembly block diagram thereof.
Fig. 3 is the block diagram of foot-operated aluminum alloy body, graphite oilless sintered-metal bearing and locating element thereof of the utility model.
As shown in Figure 1, this foot-operated body 5 is the monolithic extruded profiled member of aluminum alloy, body 5 contains central axle sleeve 5-1 (structure is seen Fig. 3), powder metallurgy oil-impregnated bearing 3 is equipped with at two ends in the axle sleeve 5-1, it is inner respectively with nest 4 axial location, and the tail end of mandrel 1 is added with safety washer 6, and screws with nut 7 and 8, the inner of central axle sleeve is provided with interior protective cover 2, and the outer end is provided with outer protective cover 9.Graphite oilless sintered-metal bearing 3 is the powder metallurgical bodies that soak through lubricating oil.
Assembling process referring to Fig. 1-3 explanation the utility model bicycle pedals: the two ends of body 5 pack into successively respectively nest 4, graphite oilless sintered-metal bearing 3, the left end of axle sleeve is pressed into interior protective cover 2, center from interior protective cover penetrates mandrel 1 in the axle sleeve 5-1 then, tail end is loaded onto safety washer 6, screw in nut 7 and 8, load onto outer protective cover 9, promptly install.
