Description

Wheel structure

The creative department belongs to the technical field of a wheel set, and specifically refers to a wheel set structure which has both stability and load bearing property, thereby improving the smoothness of sliding and prolonging its service life.

According to the generally heavy door panels or parts, such as the support, the wheel set is usually arranged at the top or bottom edge, and the wheel set structure is mainly as shown in the first figure, which is tied to one axis. A roller set (20) is sandwiched between the two ends of the tube (10) by a buckle (11) and a riveted flange (15), and the roller sets (20) are fixed to the shaft tube (10). The bearing (21) at both ends, the roller set (20) and the outer edge of the bearing (21) are sleeved with a plastic or rubber wheel body (22) to reduce the friction noise during rolling, and for dustproof A dust cover (25) is usually provided on both sides of the bearing (21) to reduce the amount of foreign matter or particles falling into the ball portion inside the bearing (21); however, the above conventional wheel set is actually used due to its The shaft tube (10) is a hollow tube member, and in order to provide the buckle ring (11), a concave ring groove is formed at the periphery, which causes the thickness of the shaft tube (10) to be reduced, so that the supportability is lowered, and the weight cannot be effectively carried. The bearing, and the bearing (21) simply use the buckle (11) and the riveted flange (15) to clamp the limit and the cover of the wheel body, which is insufficient in stress resistance and is easily deformed. And loose, so that the load is driven by the wheel set The stability is insufficient and shakes, affecting the overall quality. Moreover, the dust cover (25) can only partially protect the inner ball of the bearing (21), and cannot be completely closed completely, so the dustproofness is insufficient, and the dust will threaten the bearing (21). The service life of the internal balls, so how to solve the problems of the aforementioned supportability, stability and dustproofness of the wheel sets is currently expected by the industry and users.

Therefore, the creator has in-depth discussion on the problems faced by the aforementioned wheel sets, and has actively pursued solutions through years of experience in R&D and manufacturing of related industries. Through continuous efforts in research and trials, he has finally succeeded in developing. A wheel set structure that overcomes the inconvenience and trouble caused by the lack of structure in the prior art.

Therefore, the main purpose of the present invention is to provide a wheel structure, which can improve the overall structural strength and the combined strength of the wheel body, effectively improve its stability, and reduce sloshing, thereby prolonging its service life.

Moreover, the second main purpose of the present invention is to provide a wheel structure which can effectively improve the support, increase the bearing capacity, and reduce the generation of noise.

However, another main object of the present invention is to provide a wheel set structure which has a better dustproof effect, which not only avoids shortening the service life due to friction of dust particles, but further reduces noise.

Accordingly, this creation mainly achieves the aforementioned objectives and effects through the following technical means: it consists of a main pole, a two-bead set, two annular seats and two wheel bodies; Forming a bead block at each end, the two beads A bead groove is formed on the periphery of the seat segment for the bead assembly, and an annular bearing seat is disposed on the outer side of the bead group. The inner edge of the annular bearing seat is formed with a bead groove corresponding to the bead group ball. The bearing seat is rotatable relative to the main bead seat section through the bead set; and the wheel bodies are sleeved outside the annular bearing seat, and the two sides of the inner wheel edge of the same wheel are limited to both sides of the annular bearing seat. Side flange.

Therefore, through the above-mentioned technical means, the main support of the wheel set structure of the present invention has high structural strength, and the bead sets on both sides directly act on the bead seat segments at both ends of the main rod, and the overall supportability is excellent. It can effectively improve its bearing capacity, can be used for heavier loaded objects, and the bearing and the wheel body are also effectively fixed to the main rod and the annular bearing seat, so that the stability and stress resistance can be improved during operation, and effective It improves the smoothness of sliding and further prolongs its service life, thereby effectively increasing its added value and enhancing its economic benefits.

In order to enable the review committee to further understand the composition, features and other purposes of the creation, the following is a preferred embodiment of the creation, and the detailed description of the creation is as follows, and at the same time, those skilled in the art can follow the instructions.
