Abstract

The present invention relates to a transfer roller assembly for a heat treatment facility, and more specifically, to a transfer roller assembly for a heat treatment facility in which a plurality of cooling grooves are formed in a portion of the transfer roller that is exposed to the outside of the heat treatment part and comes into contact with external air, thereby increasing the contact area of the transfer roller with external air, so as to improve and sustain the air cooling effect of the transfer roller, thereby preventing the drying of grease due to heating of the transfer roller, and furthermore, by forming a grease injection hole at one end of the bracket so as to inject grease through the grease injection hole when the grease is consumed, the grease is naturally delivered and circulated according to the rotation of the internal bearing, thereby improving efficiency and maintaining a neat appearance unlike conventional external coating methods.

Description

Transporting Roller Assembly for Thermal Processing Equipment The present invention relates to a transfer roller assembly for heat treatment equipment, which can improve and sustain the air cooling effect of a transfer roller by forming a cooling groove that increases the contact area with external air on the transfer roller, thereby preventing the drying of grease due to heating of the transfer roller, and also improves efficiency by naturally delivering and circulating grease according to the rotation of the internal bearing by forming a grease injection hole in the bracket supporting the transfer roller so that grease can be injected through it, and maintains a neat appearance unlike conventional external coating methods. Generally, as described in Patent Document 1, a heat treatment facility is a facility that heats metal for the purpose of changing the properties of metal or machine parts to obtain the required strength. Typically, as shown in FIG. 1, a conveying roller (R1) is provided on the inner side of the heat treatment section (H), and a driving roller (R2) is provided on the outer lower side of the heat treatment section (H). A mesh belt (M), etc., rotates along the driving roller (R2) and the conveying roller (R1). The object to be heat treated is supported by the mesh belt (M), etc., and the heat treatment process is performed while moving inside the heat treatment section (H). Meanwhile, in the case of the above-mentioned transfer roller (R1), the central part supporting the mesh belt (M), etc., is located inside the heat treatment section (H), and both ends are exposed outside the heat treatment section (H) and are supported rotatably on the bracket (B). At this time, the bracket (B) has a bearing inserted inside to support both ends of the transfer roller (R1), allowing the transfer roller (R1) to rotate, and grease, which is a lubricant, is injected into the bearing to facilitate the smooth rotation of the transfer roller (R1). However, in a conventional transfer roller assembly including the transfer roller and bracket as described above, there is a problem in that the grease initially injected into the bearing dries out easily as the transfer roller used in the heat treatment facility is heated by receiving continuous heat within the heat treatment section. In other words, during the drying of grease, the rotation of the bearing-based transfer roller is not smooth, causing the transfer of the heat-treated object to become unstable. Consequently, there is a problem in that the heat treatment efficiency is reduced due to excessive or insufficient heat treatment of the object. Accordingly, conventionally, grease was continuously applied to the outer surface of the bearing; however, the efficiency was insufficient because the grease could not be easily transferred and circulated to the inside of the bearing, and there was also the problem of the bearing looking unsightly due to the grease being applied to the outer surface.
