Bearing is an important component in the complete set of woodworking machinery of contemporary carpenter grinder. Its main function is to support the mechanical rotating body, reduce its friction coefficient in the process of motion, and ensure its inversion accuracy. With the increasing demand for bearings, the premature damage of bearings, the short life of bearings and other problems plague every mechanical enthusiast.
What is the reason why the bearings of woodworking cold press will be damaged prematurely? How to improve the bearing life? Higher efficiency for you to analyze as follows:
Under relative loads, the number of rotations or hours experienced by bearings before pitting corrosion is called bearing life. Bearings within this life should begin to suffer fatigue damage on any bearing ring or rolling element. However, in our daily practice and application, we can remarkably observe that in the same working conditions, the appearance of common bearings, the number of practical life is very different. What is the reason for this? Brissende summarizes the following points:
1. Installation inappropriate (about 16%)
1. Too much force is exerted on the device, and the hammer on the top of the device will do great harm to the bearing, which is also the main reason for the deformation.
2. The device has errors or is not installed in the bearing position, resulting in too small bearing clearance. The inner and outer rings are not in the same revolving center, forming different centers.
Proposition: Select appropriate or professional bearing device tools, the end of the device should be tested with special instruments.
2. Pollution (about 14%)
Pollution can also lead to premature damage to bearings. Pollution refers to the entry of dust, metal chips, etc. into the interior of bearings. The main reasons include: opening the bearing package prematurely before use, causing pollution; unclean working environment of the device, causing pollution; unclean working environment of the bearing, pollution of working medium, etc.
Advocate: Do not dismantle the packaging of bearings before operation; insist on cleaning the environment of the device while installing, clean the bearings to be used; strengthen the sealing device of the bearing.
3. Poor smoothness (about 50%)
According to investigation, poor smoothness is one of the main reasons for premature bearing damage. It includes not adding smoothing agent or smooth oil in time; not adding smoothing agent or smooth oil in place; improper selection of smoothing agent or smooth oil; incorrect smoothing method and so on.
Proposition: Choose the right smoothing agent or oil, and use the right smoothing filling method.
4. Fatigue (about 34%)
Fatigue damage is a common method of bearing damage. Common causes of fatigue damage may be: long-term overload operation of bearings; failure to repair in time; inappropriate repair; aging of special-shaped grinders, etc. Proposition: Select the appropriate bearing type, periodically and timely replacement of tired bearings.
