Failure Causes Of Self-Aligning Ball Bearings, Key Points Of Operation Inspection And Daily Maintenance Skills

Self-Aligning Ball Bearings

After the installation of Timken bearing, in order to check whether the installation is correct, operation inspection shall be carried out. Self-Aligning Ball Bearings Small machinery can be rotated by hand to confirm whether it rotates smoothly.

The inspection items include poor operation caused by foreign matters, scars and indentation, unstable torque caused by poor installation and poor processing of mounting base, excessive torque caused by too small clearance, installation error and sealing friction, dll.. If there is no abnormality, the power operation can be started.

Large machinery cannot rotate manually, so the power shall be cut off immediately after no-load start, and the machinery idles. Check Self-Aligning Ball Bearings whether there is vibration, kebisingan, contact of rotating parts, dll.. after confirming that there is no abnormality, enter the power operation.

Operasi daya, mulai dari tanpa beban dan kecepatan rendah, perlahan-lahan meningkat ke operasi pengenal di bawah kondisi yang ditentukan. Selama uji coba, item inspeksi adalah apakah ada suara abnormal,

temperature change of self-aligning ball bearing, lubricant leakage or discoloration, dll.. Jika ditemukan kelainan, stop the operation Self-Aligning Ball Bearings immediately, cek mesinnya, and remove the bearing for inspection if necessary.

Timken bearing temperature can generally be inferred from the external temperature of the bearing pedestal. Namun, lebih akurat untuk langsung mengukur suhu lingkar luar bantalan dengan menggunakan lubang oli. Suhu bantalan naik secara bertahap dari awal operasi,

dan suhu biasanya stabil setelah 1 ~ 2 jam. If the bearing is not installed properly, suhu akan naik tajam, resulting in abnormal high Self-Aligning Ball Bearings temperature. Alasannya terlalu banyak pelumas, jarak bantalan terlalu kecil, instalasi yang buruk,

gesekan yang berlebihan dari perangkat penyegel, dll.. In the case of high-speed Self-Aligning Ball Bearings rotation, Timken bearing structure and wrong selection of lubrication mode are also the reasons.

The rotating sound of Timken bearing is checked with stethoscope,

dan ada suara logam yang kuat, suara tidak normal, irregular sound and other indications of Self-Aligning Ball Bearings abnormality. Alasannya adalah pelumasan yang buruk, akurasi poros atau bantalan kursi yang buruk, kerusakan bantalan, intrusi benda asing, dll..

Under the action of instantaneous high temperature, the steel surface reacts with oxygen in the air to form an extremely thin (20 ~ 30nm) thin layer of iron oxide.

It should be noted that there is a corresponding relationship between the thickness of oxide layer and the total thickness of surface grinding metamorphic layer. This shows that the thickness of oxide layer is directly related to the grinding process and is an important symbol of grinding quality.

1. Pertama, you must buy real self-aligning ball bearings. If you buy fake bearings, you won’t live long in any way.

2. Before installing the bearing, first check whether the bearing is short of oil and clean, and then install the bearing correctly after checking the parts of the machine to be installed and determining the grease and cleaning.

3. After the bearings are installed, the bearings are put into trial Self-Aligning Ball Bearings operation. After running for a while, no abnormality is found in the inspection, and the bearings can enter the service state normally.

4. To check regularly, the lubrication of each Timken bearing is very important, and the bearing is no exception. When maintaining the bearing, first check whether the bearing surface is clean. If it is not clean enough, first flush it with Self-Aligning Ball Bearings gasoline or alcohol, and then grease it.

If there is too much grease between the two bearings, do not add too much grease as long as there is grease between the two bearings. When using grease for self-aligning ball bearings, avoid contacting any part of the bearing with cotton fabric, which may cause some residual fibers to roll and cause damage.

Determine the time of each inspection, and then check whether it is short of oil and clean according to the normal time. If these points are done well, the self-aligning ball bearing can live a long life.
