Abstract

PURPOSE:To heighten the radial and axial load carrying capacity, by providing a radial bearing and a thrust bearing between the upper rotary shaft of an auger and a bearing housing surrounding the rotary shaft and mounted on a refrigerating cylinder by screws. CONSTITUTION:The upward axial load, which acts to a refrigerating cylinder 1 when ice on the inside surface of the cylinder is scraped off and pushed upwards by a spiral blade 2A, is transmitted to an upper bearing housing 8 coupled to the cylinder. At that time, the reaction force resulting from the pushing- upwards of the ice acts to an auger 2 so that the downward axial load is transmitted to the housing 8 through a nut 11 and a thrust bearing 10. The radial load of a rotary shaft 2B is carried by a radial bearing 9. According to this constitution, the axial and the radial load is carried well.

It has been confirmed through experiments that the thrust load of a large T-force ice maker can be several hundred to several tons. Therefore, in a structure in which a large thrust load is supported by a radial bearing, it is necessary to select a bearing with an extremely large capacity in order to significantly shorten the bearing weight and extend the life. plays the disadvantage of rising.

Furthermore, since the ice pushed upward is rubbing against the freezing cylinder, an upward thrust load is generated on the freezing cylinder. For this reason, when the thrust load of the auger is received by the lower bearing or drive output shaft, the load is applied to the fixing bolts of the freezing cylinder and the cage jig for the lower bearing, and the latter is applied to the cage jig (which supports the entire ice making section). = It has the disadvantage of becoming bent or damaged under load.

The lower part C of the upper bearing pawl jig (8) is fitted and is screwed to the compression jig (8), and the outer surface includes the upper inner surface of the freezing cylinder (1). A plurality of ice compression passages (11) are formed.A passage number α that is continuous with the ice compression passage α is also formed in the bearing claw jig (8). , the nut I is covered with a cover (2) that prevents the intrusion of melting water, and is screwed to the bearing housing (8). ) is connected to the end of the agitator for water discharging, and the rotation of the agitator e (; ice is released from the shooter aη, αe is the water supply pipe Oq which supplies water to the freezing circle mtu). Field and (a) are oil seals, and (2) are mechanical seals. According to the above bearing structure, the spiral teeth (2A) t: scrape away the ice that has grown on the inner surface of the freezing cylinder (1) and move it upward. When the ice is pushed up, the upward thrust load generated on the freezing cylinder (1) is transmitted to the upper bearing housing (8) connected to the freezing cylinder (1). is applied to the prison car (2), and the downward thrust load of the T-car (1) is transmitted through the thrust bearing a (2). The thrust load is transferred to the upper bearing claw jig (8) (: therefore, the upward thrust load applied to the freezing cylinder (11r) and the downward thrust load applied to the ocher (2) are mutually transferred within the upper bearing claw jig (8). This cancels out each other, and the thrust R to the cage jig (end), lower bearing claw jig (4), and porthole that fixes the freezing cylinder (1) is significantly reduced.

As described above, the present invention incorporates a thrust bearing and a radial bearing into the upper bearing pawl 7-/g, so that the respective bearings receive the thrust load and radial load of an unbalanced car, thereby greatly improving reliability. Of course, the upward thrust load applied to the freezing cylinder 4 and the downward thrust load applied to the ocher cancel each other out in the upper bearing claw, so the cage jig that supports the ice-making part and the bolts that fix the freezing cylinder and the lower bearing housing are Since no thrust load is applied to these parts, there is no need to use high-strength, expensive parts or materials, and there is no risk of deformation or damage.
Durability is significantly improved.
