How to replace the bearing of the vibrating motor? How to replace the bearing of the vibrating motor

How to replace the vibrating motor during use.

There are two main types of vibrating motors used in vibrating screens, vertical vibrating motors are mainly used in rotary vibrating screens, horizontal vibrating motors can be applied to various vibrating screening equipment, and vibrating motors are the most important excitation sources of vibrating screens, and their important position can be imagined. The vibrating motor is made of heavy-duty bearings, which can carry a certain axial load, regardless of the installation direction, and the life of the special bearing is not affected by the axial load force.

1. Fold and remove the bearing.

1) Remove the protective covers at both ends of the vibrating motor (there is no protective cover for the vertical vibrating motor), and record the percentage value of the excitation force when the eccentric block is working, so as to restore the original working state during installation;

2) Remove the shaft at the end of the two shafts with retaining rings;

3) Unscrew the outer eccentric block to fasten the bolts, remove the outer eccentric block, and remove the shaft key if there is a shaft key. Unscrew the inner eccentric block to fasten the bolt, and remove the inner eccentric block;

4) Remove the bearing seat hold-down bolt, screw into the bearing seat with a suitable bolt to remove the screw hole, and eject the bearing seat from the casing;

5) Remove the bearing gland from the bearing seat, press the bearing out of the bearing seat or eject it with a suitable bolt;

6) If the bearing is a cylindrical roller bearing with a separable inner and outer jacket, the inner sleeve of the bearing should be removed from the shaft and put into the outer jacket of the original bearing;

7) Thoroughly clean the oil stains of each part.

2. Install the bearing.

When replacing a vibrating motor with a new bearing, it is necessary to use the same bearing as the original model.

1) The bearing is washed with kerosene, pressed into the bearing seat, filled with Shell No. 3 lithium grease to two-thirds full to the roller of the outer ring of the bearing, applied evenly with clean hands, installed the bearing gland, and pressed the bearing gland with the fastening bolt coated with bolt anti-loosening glue;

2) The bearing is a cylindrical roller bearing with separable inner and outer coats, and the inner bearing should be sleeved on the rotating shaft and put in place;

3) Install the bearing seat on the casing, if there is a grease oil injection hole, it must be aligned with the position. Press the bearing seat with a fastening bolt coated with bolt anti-loosening glue;

4) The inner and outer eccentric blocks are installed on the rotating shaft and in place, and those with shaft keys should be loaded into the keyway and then installed with the outer eccentric block, and the shaft is installed on the rotating shaft with a retaining ring;

5) Tighten the fastening bolt of the eccentric block, rotate the adjustable eccentric block so that it reaches the angular position before removal and tighten its fastening bolt. After the above assembly is completed, the rotating shaft should have a certain axial series movement;

6) The protective covers at both ends of the upper vibration motor are fastened with screws.

With professional bearing tools.

1) The bearing is washed with kerosene, pressed into the bearing seat, filled with Shell No. 3 lithium grease to two-thirds full to the roller of the outer ring of the bearing, applied evenly with clean hands, installed the bearing gland, and pressed the bearing gland with the fastening bolt coated with bolt anti-loosening glue; 2) The bearing is a cylindrical roller bearing with separable inner and outer coats, and the inner bearing should be sleeved on the rotating shaft and put in place; 3) Install the bearing seat on the casing, if there is a grease oil injection hole, it must be aligned with the position. Press the bearing seat with a fastening bolt coated with bolt anti-loosening glue; 4) The inner and outer eccentric blocks are installed on the rotating shaft and in place, and those with shaft keys should be loaded into the keyway and then installed with the outer eccentric block, and the shaft is installed on the rotating shaft with a retaining ring; 5) Tighten the fastening bolt of the eccentric block, rotate the adjustable eccentric block so that it reaches the angular position before removal and tighten its fastening bolt.

There are two main kinds of vibrating motors used with vibrating screens, horizontal vibrating motors can be applied to various vibrating screening equipment, and vibrating motors are the most important spherical source of excitation belt seat for vibrating screens, regardless of the installation direction, the main rolling mill of vertical vibrating motor should be applied to rotary vibrating screens, and its important position can be imagined. The vibration motor is made of heavy-duty bearings, which can carry a certain axial load, and the bearing life of the bearing pad factory is not affected by the axial load force.

The bearing is washed with kerosene, evenly smeared with clean hands, pressed into the seat, filled with Shell No. 3 lithium grease to two-thirds full to the roller of the needle roller bearing in the outer ring of the bearing, installed the bearing gland, and coated with bolt anti-loosening glue. Tighten the one-way bearing bolt and press the gland.

The bearing is a cylindrical roller bearing with a separable inner and outer sleeve, and the inner sleeve of the bearing should be placed on the shaft of the rotating spherical ball bearing and in place.

When the vibrating motor is replaced with a new shaft, it must be the same as the original model.

The inner and outer eccentric blocks are installed on the rotating shaft and in place, and those with shaft keys should be fully equipped with roller bearing keys into the keyway and then install the outer eccentric block, and the shaft is installed on the rotating shaft with a retaining ring.

Install the protective covers at both ends of the vibrating motor on the bearing and fasten it with screws.

Attach the seat to the casing, and if there are grease filling holes, they must be aligned. Press down on the housing with a fastening bolt with anti-loosening rubber for a spherical roller bearing bolt.

Tighten the eccentric block fastening bolt so that it reaches the angular position before removal and tighten its fastening bolt. After the above assembly is completed, the adjustable eccentric block of the rotating shaft should have a certain axial bearing seat in series.

Remove the shafts at both ends with retaining rings. The tapered roller bearing removes the gland from the seat, presses it out of the seat or ejects it with other angular contact ball bearing bolts suitable for it, and dismantled. Remove the seat hold-down bolts, screw into the seat with suitable bolts to remove the screw hole, and eject the bearing seat from the housing.

Unscrew the outer eccentric block and the linear motion bolt of the row fastening screw, and remove the shaft key if there is an axis key. Unscrew the inner eccentric block to fasten the bolts, remove the outer eccentric block, and remove the inner eccentric block.

Thoroughly clean the oil stains of each part.

Remove the protective covers at both ends of the vibrating joint motor (vertical vibrating motor does not have protective covers), and record the percentage of excitation force of the special spherical bearing when the eccentric block is working, so as to restore the original working state of the SKF bearing during installation. If the shaft is a full-mounted cylindrical roller bearing with a separable inner and outer jacket cylindrical rollers, the inner sleeve should be removed from the early shaft and put into the original bearing jacket.

Summary. When the spherical roller bearing is used for a long time, the bearing will be lubricated to ensure that the service life of the spherical roller bearing is prolonged.

Here's the relevant information for you to take a look at Ha <>

<> spherical roller bearings are called three types of bearings in China. Spherical roller bearings are a type of radial bearings, which can bear radial loads and can also bear bidirectional bearing loads. The spherical roller bearing has a large radial bearing capacity, and has the function of self-alignment, which has low requirements for the machining accuracy of the casing, avoids the installation error or shaft deflection and affects the use of the bearing, and has large vibration and impact resistance.
