Abstract

The present invention relates to a casing for installing a worm shaft of an ice-shaving machine. The present invention relieves friction and abrasion occurring during a process of the worm shaft to rise and fall, combines the casing and a pulley with a bearing, fundamentally removes the cause for iron powder, which is the result of abrasion due to friction, prevents iron powder from being mixed with ice, and makes the operation of the ice-shaving machine smooth. The top of the casing is combined with a pulley on an exterior which has a pulley support bearing. A worm shaft support bearing is placed on the inside of a hollow part of the pulley and the front end on the bottom of a hollow part of the casing to support the worm shaft. A pulley, which is placed on the top of the casing, is combined with a bearing, and friction is prevented from occurring in between the casing and the pulley. The worm shaft support bearing, which is placed on the central point of the pulley and the front end on the bottom of the casing, supports the worm shaft. Since the worm shaft rises and falls on the casing, iron powder, which is generated by friction and abrasion, is fundamentally removed, and the ice-shaving machines operation is smooth since there is little friction.

As shown in Figs. 2 to 4, the casing 1 for installing a worm shaft according to the present invention has a worm shaft support bearing 2 in a lower end groove 1a of a hollow portion, and a hood 1b The pulley 4 is coupled to the pulley support bearing 3. The pulley 4 has a central step 4a and a lower step 4b and a central step 4a, And a lower end step 2b of the pulley 4 is fitted to the outer periphery of the pulley support bearing 3 at the upper part of the casing 1 to engage with the casing 1, And the worm shaft is supported by the worm shaft support bearings (2) (2a) of the pulley (4).

Reference numeral 20 denotes a worm shaft, reference numeral 21 denotes an ice block body, reference numeral 22 denotes a bolt, reference numeral 23 denotes an ice fixing plate, reference numeral 24 denotes a brake drum, reference numeral 25 denotes a brake band, reference numeral 26 denotes a worm gear, reference numeral 27 denotes a worm gear shaft support bearing, A motor 29, a belt 29, a fixed blade 30, a rim 31, and a rim 34.

When the casing and the power transmission pulley are connected to each other by a bearing and the bearing is accommodated in the middle step of the pulley and the bearing of the inner diameter of the casing supports the worm shaft, the worm shaft is rotated by the rotation of the worm gear The outer surface of the worm shaft does not come into contact with the casing, and the pulley does not come into contact with the upper surface of the casing, so that no load is generated, so that the lifting operation of the worm shaft is smooth. Moreover, The snow and ice coming out from the shovel are hygienic because there is no mixing of the flour and there is an advantage that the casing can be easily manufactured and installed on the body and the maintenance can be simplified.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

2 to 4, the casing 1 for installing the worm shaft of the ice machine is provided with a worm shaft support bearing 2 on the hollow lower front groove 1a, The pulley 4 is coupled to the outer periphery of the pulley support bearing 3. The pulley 4 has a central step 4a and a lower step 4b formed on the inner diameter of the pulley 4. The center step 4a Is formed by coupling a worm shaft support bearing 2a to the outside of the pulley support bearing 3 at the lower step 4b.

The casing 1 and the pulley 4 are formed in the upper and lower parts together when the pulley 4 is coupled to the outside of the pulley support bearing 3 on the upper side of the casing 1 and the lower part of the casing 1 and the pulley 4 The worm shaft support bearings (2) and (2a) are located at the upper and lower two stages on the concentric line.

5 to 7, the casing 1 is fixed to the ice-maker main body 21 with the bolts 22, and the casing 1 is fixed to the pulley 4 and the casing 1, The worm shaft 20 is inserted into the hollow portion of the support bearing 2 (2a), and the ice fixing plate 23 is coupled to the lower end of the worm shaft 20. At the opening of the casing 1, The worm gear shaft support bearing 27 is fixed to the ice-maker main body 21 on both sides of the worm gear shaft 26a having the worm gear 26 and the brake drum 24 so as to be diagonal to the shaft 20, The worm shaft 20 and the worm gear 26 are disposed diagonally to engage the teeth and the brake drum 24 is provided with a brake band 25 so as to adjust the rotational force. The lug worm shaft 20 has a projecting portion 31 provided on the pulley 4 and a worm shaft 20 disposed on the lug groove 32 provided in the longitudinal direction of the worm shaft 20, As the rotation to the engagement state dolteok 31 will be written spar.
