Description

Bearing of ventilator v-belt pulley in air conditioner

The present invention relates to a blower bearing and a V-type belt pulley of an air conditioner, and more specifically, a bearing and a V-belt pulley mounted on the blower of an air conditioner, an oil-free type of SKF automatic adjustment block bearing and a tapered lock taper pulley. (TAPER LOCK TYPE PULLEY) is used to minimize noise and vibration while operating the air conditioner's blower, as well as to increase the life of the blower, and to provide convenience when selecting and maintaining the correct air volume of the air conditioner. It relates to a V belt and a bearing that allows.

In general, the air conditioner casing is a cooling unit for heat exchange between the blower and the motor for driving the air. It consists of a heating coil and a humidifier.

These components are the core parts of the air conditioner and operate in the air conditioner, thereby forcing the air in the room to be sucked by the blower to cool. Through heating coil and humidifier, it creates temperature and humidity conditions and pleasant air condition that requires air condition, and supplies it back to the room.

Of these components, the mounted bearings and V-belt pulleys of the blowers play a significant role in the performance and life of the blowers.

Therefore, the ball bearings used in the related art adopt a knocking nut (KNOCKING-NUT) method using a set screw (SET-SCREW), causing a problem in that the shaft is eccentric during assembly.

If the shaft is mounted eccentrically as described above, it may cause noise and vibration during operation, resulting in shortening the bearing life and inconvenient maintenance due to grease injection, and V-belt pulley (V-BELT PULLEY) Has always been a problem because it is impossible to accurately select the air volume due to the use of the INCH PULLEY of the general key nut.

The present invention has been made to solve the above problems, using the bearing and V-belt pulley mounted on the air conditioner blower and the oil-free SKF automatic adjustment block bearing and taper lock taper pulley (TAPER LOCK TYPE PULLEY) It is possible to minimize noise and vibration while operating the air conditioner's blower, as well as to increase the life of the blower, and to provide convenience when selecting and maintaining the correct air volume of the air conditioner. will be.

In order to achieve the above object, a V-type belt and a V-type belt pulley and a blower (F) which transmit a motor (M) and a driving force to the blower (F) for driving the air conditioner during operation of the air conditioner. In the conventional blower structure is coupled to the bearing supporting the shaft,

Inserting a blower shaft with a plurality of screw grooves formed outwardly and having a constant taper on the outside into a hole formed in the pulley, and coupling the tapered lock bush coupled to the pulley to the shaft and then After inserting the screw into the plurality of fastening grooves formed on the outer surface, tighten the screw and the tapered lock bush presses the shaft and combines it so that the shaft and the data lock bush are integrally formed so that the pulley and the shaft are integrally combined. It is to provide an easy to noise, vibration, performance and maintenance during operation required for the air conditioner blower and to increase the life.

FIG. 2 is a detailed cross-sectional view of the bearing of the 'ga' portion of FIG. 1,

FIG. 3 is an exploded perspective view of the bearing of portion 'B' of FIG. 2.

Blower (F) and V-type belt (2) and V-type belt pulley (3) and blower (F) for transmitting the driving force (M) and driving force to the blower (F) for driving the air conditioner. In a conventional blower structure in which a bearing 5 supporting a shaft 1 is connected to

Inserting and coupling the blower shaft 1 with a tapered lock bush 4 having a plurality of screw grooves formed on the outside and a constant taper on the outside in a hole formed in the pulley 3, and coupled to the pulley 3 Insert the taper lock bush 4 into the shaft 1, insert the screw 6 into the plurality of fastening grooves 7 formed on the outer surface of the taper lock bush 4, and then tighten the screw 6 to taper lock bush. Compression of the shaft 1 and the shaft 1 and the data lock bush 4 are combined so that the pulley 3 and the shaft 1 are integrally coupled.

The operation of the present invention is as follows.

A plurality of screw grooves are formed in all directions so that the blower shaft 1 has an angle of 90 ° to the outside, and a tapered lock bush 4 having a constant taper on the outside is inserted into the hole formed in the pulley 3 and coupled thereto.

When the taper is formed at an angle to the outside of the tapered lock bush 4, the pulley 3 coupled to the bush also has to be formed with a constant taper on the inner side to enable coupling.

The shaft 1 is inserted into the tapered lock bush 4 coupled to the pulley 3, and then the screw 6 is inserted into the plurality of fastening grooves 7 formed on the outer surface of the tapered lock bush 4.

The pulley (3) and the shaft (1) by tightening the screw (6) inserted into the fastening groove (7) by the tapered lock bush (4) by pressing the shaft (1) to combine the shaft and the data lock bush integrally ) Is to be combined as one.

Therefore, in the conventional method of directly inserting the shaft 1 into the pulley 3 and fixing the eccentricity by inserting one medium in the middle, the eccentricity is solved. It is.

(Variants, applications and legal interpretations)

The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

Therefore, the present invention uses the bearing and V-belt pulley mounted on the blower of the air conditioner using the SKF automatic adjustment block bearing and the taper lock taper pulley (TAPER LOCK TYPE PULLEY) to prevent noise, In addition to minimizing vibration, as well as increasing the life of the blower, it is effective to provide convenience in selecting and maintaining the correct air flow rate of the air conditioner.
