Modification method of bearing seat slider in vacuum filter

For the problem of the vacuum filter bolt wear, a boss is designed on the slider, a groove is designed on the bearing box, the boss and the groove are tightly buckled, and the action area of ​​the cylinder acting on the drive roller slider is increased. The role of the convex side is to share the front and back shear forces (main force) of the bearing, so that the position of action is changed from one point to one side, and the original two main force fixing bolts. Instead of four limit bolts, the fixing bolts are not subject to the main force, but only play a limiting role. At the same time, the shear force acting on the cylinder is reduced when starting and stopping. To extend the service life of the bearing and the main drive roller shaft is:

1 First of all, carry out the transformation of the bearing block to install the bearing seat, and make a limit position of the boss on the slider and take part of the role of longitudinal shear force.

2 The improvement of the bearing seat. The original UCP bearing was changed to a separate bearing seat. The bearing was replaced by a 2213 heavy-duty bearing. The inner sealing ring was sealed with a frame rubber ring. The bearing seat was fixed on the slider with four M16 bolts. The bearing seat was designed. The groove fits with the boss on the slider to achieve the purpose of increasing the stress point and dispersing the shear force on the bolt.

3 In order to overcome the corrosion of the bearing seat in the on-site environment and increase the service life of the bearing seat, a stainless steel material is used for material selection.

The inside seal of the bearing seat is sealed with a frame apron, and a bearing box is installed at the same time to prevent water from entering the bearing and damaging the bearing.
