YOCH Bearing

Grease has good adhesion, wear resistance, temperature resistance, rust resistance and lubricity. It can improve high temperature oxidation resistance, delay aging, dissolve carbon deposits, prevent the agglomeration of metal wear debris and oil stains, and improve Mechanical wear, pressure and corrosion resistance.

Oil seals are precision components, and improper assembly and storage will affect performance. Pay attention to the following when transporting and storing oil seals:

It is very suitable to lubricate the FAG bearings in the reduction box with lubricating oil, because the oil achieves the purpose of lubrication of the gears and FAG bearings at the same time by splashing. 6) The grease in the FAG bearing is gradually contaminated by products of product wear, abrasives, products that penetrate through the sealing device from the outside and age themselves. If not replaced in time, it will cause accelerated wear of the FAG bearing, and when using liquid lubricants , can be filtered to ensure its normal operation.

The ambient temperature during measurement is specified as 20°C. The temperatures of bearings, gauge blocks, standard parts and measuring instruments must all be the same. The above method of placing them on the same metal plate can achieve the necessary temperature balance as quickly as possible, otherwise It takes hours or even days to achieve this balance. In order to obtain correct measurement results, foreign countries rely on mechanization of measurement to avoid human hands coming into contact with these objects, or wear insulating gloves to operate.

The phenomenon of size or shape change of INA stainless steel bearings or components due to stress is called deformation. Due to harsh working conditions, the mechanical equipment at the production site is often overloaded and it is very common for some bearings to deform. Their deformation will accelerate the wear and even breakage of other related parts, and may also cause damage to the system series bearings or the entire equipment, causing equipment accidents, so the harm of deformation is quite serious.

There are two ways of axial preload for bearings: one is constant pressure preload and the other is positioning preload. Under constant pressure preload, the radial stiffness of the bearing increases slightly as the rotational speed increases, while the axial and angular stiffness decrease rapidly. Under positioning preload, the radial, axial and angular stiffness of the bearing increase rapidly with the increase of rotation speed, but the increase of axial and angular stiffness is relatively gentle.

Dental drill bearings are special bearings for dental handpieces. There is a key component on the dentist's handpiece, called the high-speed dental drill assembly. It consists of a shaft, turbine, spring chuck, spring washer, back cover, shell, rolling bearing, and rubber positioning ring. , the rolling bearing used is called a dental drill bearing.

Pollutants in lubricating oil include various substances mixed in the working medium that are harmful to the surface life of internal combustion engine parts, such as solid particles, water, exhaust gas, diesel (gasoline) oil and polluted energy.

In the surface process, such as grinding a surface on a vertical single-head grinder, the following factors may cause burns if the operating specifications are correctly followed. a. The grinding wheel shaft moves, increasing the instantaneous grinding amount and causing burns; at this time, the grinding wheel shaft bearing must be tightened or the bearing must be replaced. b. The disk on the workbench jumps or rotates unevenly, which increases the amount of instantaneous grinding and causes burns; various components of the disk reducer, such as worm gears, worms, etc., must be inspected and worn parts replaced.
