Abstract

The utility model discloses a middle axle rolling part for a rickshaw, which is characterized in that bearings are arranged on both ends in the outer sleeve of the rickshaw; the inner ring of the bearing is clamped and sheathed with a rolling shaft; a lining is arranged between two bearings in the outer sleeve of the rickshaw. The utility model has the advantages of low noise, small vibration and swing, low failure rate, simple assemblage and high efficiency. People feel comfortable, the used force is correspondingly reduced, a plurality of prior body-building instruments can be improved by a grade, and the production quality can be increased.

Description

Rickshaw axis rolling member

The utility model relates to the rolling friction structure of the rickshaw that is used for body-building apparatus, specifically axis rolling member wherein.

The axis rolling member of existing rickshaw is by the car overcoat, the roller bearing and the corresponding rolling member that are contained in the car overcoat are formed, and rolling member is by the axle bowl, steel ball is formed with the axle shelves, because design-calculated structure and technology assembly relation exist the axle shelves and the steel ball of roller bearing, axially loaded between axle bowl is big, and vibration values height, transmission horsepower input are big, and mechanical life is short.The fault rate height, the deficiency that efficiency of assembling is low.

The purpose of this utility model is to provide a kind of improved rickshaw axis rolling member, and it can overcome some shortcomings of the prior art.

The technical solution of the utility model is achieved in that rickshaw axis rolling member, it mainly comprises the car overcoat, be contained in roller bearing and corresponding rolling member in the car overcoat, it is characterized in that: the bearing neck bearing all is equipped with at the two ends in the car overcoat, inner ring is fastened on the roller bearing, also is provided with lining between the two bearings in the car overcoat.

The utility model has replaced the rolling member that axle bowl, steel ball, axle shelves are formed with antifriction-bearing box, because rolling members such as original bowl are the forging and pressing processing, low precision, and antifriction-bearing box is metalworking, precision is higher, it compared with prior art, have noise little, the vibration rock advantage little, that fault rate is low, assembling is simple, efficient is high, it is comfortable that the end user feels, level and smooth friction drag is little, the corresponding minimizing of exerting oneself can make on more existing body-building apparatus a class, has improved product design.

Fig. 1 is the structural representation of the utility model one embodiment

The utility model will be further described below in conjunction with drawings and Examples

The utility model mainly comprises car overcoat 1, be contained in roller bearing 2 and corresponding rolling member in the car overcoat 1, it is different from prior art: bearing 3 is equipped with at the two ends in the car overcoat, the inner ring of bearing 3 is fastened on the roller bearing 2,3 on the car overcoat 1 of present embodiment and bearing are connected by nut sleeve 5, junction with nut sleeve 5 in the car overcoat is provided with negative thread, one end of nut sleeve is provided with the outside thread that matches, the other end cutting ferrule of nut sleeve is lived the outer ring of bearing, also be provided with lining 4 between the two bearings in the car overcoat, the length of lining 4 can be slightly larger than the length between two grades of limits of roller bearing in an embodiment, thereby guarantee stability that bearing rotates in roller bearing and can with the cooperating of car overcoat, the roller bearing both ends are tetragonal body tapering cylinder, there is a hole on the top, can make things convenient for the loading and unloading of tread plate, make its firm position, circle side's flute profile interface on nut sleeve, also being provided with, with the general cylindrical side flute profile instrument loading and unloading of cooperation with standard, nut is with two classes in an embodiment, one class is the setscrew nut cover, one end and car overcoat are also firmly tight, and its other end engages with outside race; Another kind of is that the nut sleeve of living can be revolved difference according to car overcoat length, but spinning in and out tighten during assembling, it is fixing to guarantee to closely cooperate between bearing and lining.
