As shown in fig. 1, an embodiment of the present invention provides a sprocket wheel assembly 100. The idler sprocket assembly 100 may generally include a support base 102, an idler sprocket 104, and a shaft cover 106. Specifically, the support 102 may be mounted on a work machine walking beam 200 during actual assembly, as shown in FIG. 2. By mounting the mount 102 on the walking beam 200, the entirety of the idler sprocket assembly 100 can be assembled in place.

Further, with respect to the carrier roller 104, in one embodiment of the present invention, for example, the carrier roller 104 may include an axle 108, a rolling bearing (not shown) disposed on a body of the axle 108, and a wheel body 130 disposed on the rolling bearing. Where the axle 108 may be relatively stationary in use, the wheel body 130 may engage and rotate with a track of the work machine. Specifically, the carrier roller 104 may be disposed on the support 102, such as by mounting the axle 108 of the carrier roller 104 on the support 102, thereby enabling assembly of the carrier roller 104 with the support 102.

In addition, the axle cover 106 can be covered on the axle 108 of the carrier roller assembly 104 and contact-engaged with the axle 108, and then the axle cover 106 and the support 102 can be detachably connected together, thereby completing the integral assembly of the carrier roller assembly 100. The structure of the assembled idler sprocket assembly 100 is shown in fig. 1 and 2.

As can be seen from the above embodiments, when the carrier sprocket assembly 100 is actually used, the shaft cover 106 is connected to the support 102, so that the carrier sprocket 104 can be clamped and installed between the support 102 and the shaft cover 106 in a simple installation manner, and it can be ensured that the carrier sprocket 104 does not displace in the radial direction during use, thereby ensuring that the carrier sprocket 104 is not easily disengaged.

With continued reference to fig. 1 and 2 in conjunction with fig. 3, in an embodiment of the present invention, for the support 102, a limiting groove 110 may be formed on the support 102 in order to fit the axle 108 of the carrier roller 104 on the support 102 and limit the carrier roller 104. Specifically, the retaining groove 110 may be formed by a pair of sidewalls 112 spaced apart from each other and a bottom wall 114 connecting the pair of sidewalls 112. In other words, the pair of side walls 112 and the bottom wall 114 together form the overall channel-like shape of the retention channel 110, as shown in FIG. 3. During assembly, a portion of the axle 108 may be supported within the retaining groove 110, such as by being inserted or recessed into the retaining groove 110.

Further, referring to fig. 1 and 2 in combination with fig. 4 and 5, in an embodiment of the present invention, in order to match the limiting groove 110 and limit the chain wheel 104, a limiting plane may be formed on two ends of the axle 108 opposite to each other. Specifically, as shown in fig. 4 and 5, the retaining plane formed on each end of the axle 108 may include a retaining bottom surface 116 and a pair of retaining side surfaces 118. In actual machining, the bottom stop surface 116 and the pair of side stop surfaces 118 may be machined inwardly in the axial direction from the end of each end by any suitable means, such as a milling process, to form the structure shown in fig. 4 and 5.

Because the retainer bottom surface 116 and the retainer side surface 118 are machined to a distance above the hub 108, the body of the hub 108 remains cylindrical. Thus, abutment surfaces 120 are formed where the restraining bottom surface 116 and the restraining side surface 118 meet the body of the axle 108, respectively. Through the matching of the bottom wall 114 and the limiting bottom surface 116, the matching of the side wall 112 and the limiting side surface 118, and the matching of the abutting surface 120 and the support 102 and the limiting groove 110, the displacement of the chain supporting wheel 104 in the axial direction can be effectively limited, so that the chain supporting wheel 104 is further ensured not to be easily disengaged.

Referring again to fig. 4 and 5, in an embodiment of the present invention, for the axle 108, each end of the axle 108, in addition to being formed with a retaining plane, also retains a section of arc as a top arc 122. Specifically, the top arc 122 may be located between the pair of stop sides 118 and may be curved and shaped to conform to the shape of the axle cap 106, as shown in FIGS. 1 and 2.

In actual assembly, the curved body 124 of the axle cap 106 may conform to the shape of the axle 108 of the chain wheel carrier 104, such as to the top curve 122 of the axle 108, and the flange of the axle cap 106 may be removably coupled to the seat 102 via fasteners 128 to form the unitary structure of the chain wheel carrier assembly 100 shown in fig. 1 and 2.

In an alternative embodiment, as shown in FIG. 6, to enable the carrier roller 104 to be securely retained on the seat 102, the opposite ends of the arcuate body 124 of the axle cap 106 may be respectively formed with flanges 126 as described above, and the pair of flanges 126 may extend outwardly in opposite directions from each other to form the structure shown in FIG. 6. In actual assembly, each flange 126 may be removably coupled to the support 102 by fasteners 128, as shown in FIG. 1.

Further alternatively, in the embodiment of the present invention, in order to ensure that the two ends of the axle 108 of the carrier roller 104 are uniformly stressed, the carrier roller assembly 100 may be provided with a pair of the supports 102 as described above and a pair of the axle covers 106 as described above adapted to the pair of supports 102. Specifically, as shown in fig. 1 and 2, the carrier roller 104 may be disposed between the pair of seats 102 when actually assembled, i.e., the pair of seats 102 are supported by both sides of the carrier roller 104. When the chain wheel 104 is mounted, both ends of the wheel axle 108 may be respectively disposed on the pair of supports 102. In this way, the stress on the two ends of the axle 108 of the carrier roller 104 can be more uniform, so that the axle 108 is not easy to deform.
