Description

Eccentric prevention device

The present invention is supported by a motor and a pump pulley connected by a V-belt on one side of the end of the pump shaft and the motor shaft connected to the pump spaced apart from the motor, and supporting from the bottom, the end of each of the motor shaft and pump shaft A pair of shaft arms to which a first support device (A) consisting of a pair of shaft arms connected to a bearing housing and two support devices composed of a connecting portion, and a housing cap incorporating a bearing housing of the first support device (A); It relates to an eccentricity prevention device composed of a second support device (B) consisting of a connecting portion.

Commonly used belt drive pumps mainly used in sewage treatment plants, V-belt pulleys and V-belts are used to receive the driving force of the motor to the pump. These belts can be driven smoothly without leaving a certain tension.

However, due to tension and continuous rotation of the bearing, bearing wear on both ends of the case of the motor and pump that supports and rotates the drive shaft causes a drastic shortening of the life of the bearing. Motor damages due to short circuits, as well as the damage of accessory equipment such as inverters are frequently occurring, many devices have been developed to solve this problem.

For example, Korean Laid-Open Patent Publication No. 10-2007-29498 discloses a central axis of a cap and a central axis of an eccentric prevention spring installed below the cap so as not to be eccentric during a push operation of a push button installed on a front panel. Eccentricity prevention structure of the push button for electronic products to prevent the deflection and external deviation of the spring to prevent the eccentricity is disclosed,

In the Korean Utility Model Registration No. 20-289928, in the bucket wheel eccentricity prevention device of the branding reclaimer, the upper side inner surface of the wheel rail is supported by the upper support roller fixed to the upper surface of the base, the upper support A support bracket fixed to the base so as to be positioned between the rollers, a flow block coupled to the seesaw movement about the shaft at the top of the bracket, and sliding on an inclined upper surface of the flow block by adjustment bolt shafts, respectively. A bucket wheel eccentricity preventing device of a branding reclaimer is disclosed, which is composed of a support block to be installed and an adjustment roller coupled to each of the support blocks and having an upper side supporting an inner circumferential surface of an upper side of the wheel rail. .

In general, tension and continuous rotation of the bearing support the drive shaft, bearing bearings are installed at both ends of the rotating motor and pump, which causes a short life of the bearing, which causes damage to the inpeller, rotor and stator. The motor damage due to the short circuit, as well as the damage of the accessory equipment such as the inverter frequently occurs, and to provide an effective eccentricity prevention device is a problem to be solved by the present invention.

The present invention is to solve the above problems, by installing a bearing at the end of the drive shaft separately, and simultaneously supporting the bottom and shaft between the motor shaft and the pump shaft to reduce the load on the bearings installed on both ends of the motor and pump case It ensures stable rotation of the drive shaft and supports a pair of shaft arms and connections between the motor shaft and the pump shaft to counter the tension of the belt. It is a solution to the problem to be achieved by the present invention to provide an anti-eccentric device configured to be supplemented so that the bearing installed separately is firmly supported.

The present invention aims to solve the major defect that causes the motor and pump bearings to burn out due to the belt tension, which shortens the bearing life and even damages the bearings. If any one of the bearings is abnormal, it can prevent sudden burnout, so the motor and pump can be stably maintained and used.

In order to achieve the above object, the present invention couples a pulley to an inner side of a shaft connected to a motor and a pump, and installs a housing having a bearing 24 at the end of the shaft to disperse the tension of the belt and secure the stability of the driving shaft. The housing is divided into a housing cap in which the bottom surface and the shaft arm to be fixed are integrally formed, and a housing cap is built in the upper portion of the shaft arm to support the motor and the pump. The housing and the housing cap are firmly coupled to each other by a bolt and a nut, and the housing cap has a groove for moving the bolt, so that the distance between the pair of shaft arms can be adjusted by adjusting a connection part, and the shaft is computed between the shafts. Connected with bolt-type connecting threaded bolts (15), which are structured to be fixed with four nuts (16) after proper length adjustment. It relates to a bearing and its supporting device for preventing wear.

The present invention is provided with a housing (18, 18-1) and a housing cap (19, 19-1) with a bearing (24, 24-1) is built in the shaft end of the pump (1) and the motor shaft (11) on the housing cap The shaft arms 14-2 and 14-3 are integrally formed to support between the pump shaft 3 and the pump shaft 3. The shaft arm is connected to each other by a connecting bolt (15) in the form of a computer bolt type is adjustable in length and is configured to be fixed by two nuts (16, 16-1), respectively.

In addition, the shaft arms (14, 14-1) are integrally formed in the housing (18, 18-1) to support from the bottom surface and the length can be adjusted by being connected to the connecting bolt (15) in the form of a computer bolt like Each of the two nuts 16, 16-1 is configured to be fixed to the length adjusted.

The design of the present invention moves and installs the pulleys of the motor and pump to the inside of the shaft as shown in Figure 2 and the housing and the housing cap for fixing the bearing after inserting the bearing is installed at the end of the shaft, each with four bolts and nuts Are combined. In order to connect both shaft arms, the nut-shaped portion was formed integrally with the shaft arm to the outside of the belt so that the length adjustment was possible by turning the connecting threaded bolt 15.

As shown in FIG. 3, the second support device B is composed of a fixing device and a bearing housing cap for supporting the motor and the pump, and the height of the shaft is different because the capacity and size of the motor and the pump are different depending on the intended use. Irregular spacing between the pair of shaft arms is also irregular, and the four grooves 22 and 22-1 of the housing cap allow the spacing to be adjusted by adjusting the connection between the pair of shaft arms. It is configured to be applicable.

As shown in FIG. 4, the first support device A for supporting from the bottom is firmly fixed with four bolts 22 and 22-1 in combination with the housing cap, and the shaft arm is integrally formed with the bearing housing. It is connected to the connecting bolts (15) in the form of computer bolts and fixed with four nuts (16, 16-1) after adjusting the correct height.
