Tips: Why does the gear motor vibrate?

Armature imbalance. Due to the centrifugal force generated by the unbalanced mass during rotation, a rotational force acts on the bearing, causing vibration of the motor. When the air gap is uneven, the main engine is not tightly fixed, or the rigidity of the base and the end cover is poor, vibration will be aggravated. Therefore, if the rotor is found to be unbalanced during the inspection, it must be rebalanced.
The radial clearance of the bearing is too large, and the outer ring and the end cover loosen together. When assembling, the bearings should be inspected. Bearing and journal, bearing seat must meet the requirements, otherwise it must be sprayed or brushed to deal with the process, to avoid bearing vibration caused by poor. For worn bearings, the frequency of vibration and noise during the operation of the motor is relatively high and it is easy to judge. In this case, bearings should be replaced.
Manufacturing error or deformed operation of the seat, end cover and other important braces. The shape and position error on the fitting surfaces of seat, end cover and other important rotor braces, particular the deformation of important braces (such as seat, end cover) of large and medium motors after long-term operation, make the bearing to produce an interference force, thus leading to the motor vibration.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
