Abstract
The utility model relates to a rotate axle of bicycles and small-sized tricycles, which is characterized in that both ends of an existing rotary axle are respectively provided with an axle bearing fixing ladder on the position for fixing a fixed axle and an intermediate axle. A sealing integral bearing is adopted to replace a steel bowl structure and a dispersed ball structure. The utility model has the advantages of small abrasion, portability, labor saving and long service life.
Description
The utility model relates to a kind of mechanical drive shaft, particularly a kind of bicycle, small tricycle turning cylinder.
At present, the turning cylinder of bicycle, small tricycle is cylindrical, steel bowl, the ball that looses, lock head must be assembled into rotating mechanism with axle, and the rotation wearing and tearing are big, poor sealing performance, and service life is short.
The purpose of this utility model is for overcoming above-mentioned weak point, and provides a kind of bicycle, small tricycle turning cylinder of adapted integral seal bearing, little, the long service life of wearing and tearing.
The purpose of this utility model be achieved in that bicycle, small tricycle turning cylinder be existing turning cylinder two ends install and fix shaft part and middle shaft part place is manufactured with a bearing fixing ladder respectively.
Fig. 1 is an axis constructional drawing of the present utility model;
Fig. 2 is the forward and backward axle construction figure of the utility model.
Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.
As shown in Figure 1, the shaft part that installs and fixes at axis two ends is an optical axis 1, and they and middle shaft part 2 places are manufactured with a bearing fixing ladder 3 respectively, and a back-up ring circular groove 4 is arranged respectively between bearing fixing ladder 3 and the optical axis 1.
As shown in Figure 2, shaft part 5 cars that install and fix at forward and backward axle two ends are shaped on screw thread, and they and middle shaft part 2 places are manufactured with a bearing fixing ladder 3 respectively.
The utility model is owing to adopt above design, and employing leak tightness integral metal replaces the steel bowl, the roll structure that looses, and it is little, light, laborsaving to wear and tear, long service life.
