About jiaxing bearing retainer materials related knowledge introduction of jiaxing bearing group sales co. , LTD. (
The company)
Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center.
Jiaxing bearing retainer materials related knowledge introduction cage is mainly used to keep rolling body space, adjacent to prevent direct contact roller, keep bearing friction and heat at the lowest temperature.
Type of bearings for separation, also can be used to maintain rolling element does not fall off.
In some bearing, such as thrust cylindrical roller bearings, needle roller bearing or can also be used to guide roller.
In the grease lubricated bearing cage can also play the role of reserve grease, so as to improve the bearing lubrication.
Jiaxing bearing roller bearing cage from the friction, resilience, and the mechanical stress by inertial force.
Is also influenced by some lubricants, lubricating additive products, organic solvent, cooling fluid and its aging (
Halogenated hydrocarbons, ammonia)
The influence of the chemical reaction.
Therefore, the design and choice to maintain performance and bearing retainer material reliability is very important.
According to keep the process characteristics of different, the material basically has: a variety of stamping keep frame with steel and brass plate;
Car system entities cage use steel, brass Hpb59-30 more
1, bronze, aluminum alloy and phenolic adhesive, etc.
In addition, there are powder metallurgy and nylon, etc.
Standard cage rules for each series of different sizes of bearing a cage structure for this type of bearing with standard structure.
This cage has been used to confirm the performance good, can be suitable for most applications.
Due to the requirements of the product's performance, cost, and application situation is different, in a series of larger jiaxing bearing standard maintains and smaller bearing different standard cage design.
Before bearing size form the text part, the information has been included in the standard cage, and may use other information cage.
Steel cage that maintains a high strength, lighter in weight.
In order to reduce the wear and tear, maintains a general need for hardening and surface treatment.
More suitable for deep groove ball bearing, spherical roller bearing, and most of the tapered roller bearing.
In large bearings, if brass cage produces seasonal fracture, commonly used machining steel cage.
In order to improve the slip resistance and wear, some machining steel cage after carburizing to surface hardening.
The operating temperature of the steel cage of up to 300 ℃, usually from the rolling bearing mineral oil-based or soda oil-based lubricant and the influence of organic solvents, but the water will rust.
Brass cage stamping brass cage is used only for small and medium size bearings, most of the brass cage is made of casting or forging machining.
Brass cage can not be used in the temperature above 300 ℃.
It is not subject to the influence of the most commonly used lubricants, including synthetic oil and fat.
Can clean with general organic solution, but don't use dilute alkali liquor.
Nylon maintains a small or medium size of certain types of bearings, such as double row deep groove ball bearings, self-aligning ball bearings, angular contact ball bearing, spherical roller bearings and cylindrical roller bearing, etc. , using the thermal stability, has good strength and flexibility of glass fiber reinforced nylon 66 material molded shape of cage.
Because the nylon in the lubrication of the surface of the steel has good sliding resistance, and cage and rolling element contact surface machining is smooth, greatly reduced friction produced by cage.
Therefore, bearing heat and friction can achieve low degree.
Manufacturing cage of the design of the injection molding process can meet the special requirements.
Nylon cage can keep good performance under the condition of lack of oil, make the bearings in the harsh conditions to run continuously quite a time, or will not happen quickly, holding in death of further damage.
With a nylon cage bearing, must be in the operating temperature of the nylon material and its lubricants corrosion resistance.
Used as a bearing lubrication oil and grease in jiaxing, in the below table 4.
Operating temperature value listed in 1, maintains a performance not be affected.
Operating temperature, if allowed more than cage material aging.
Cage is overheating, the longer the faster aging process.
The operating temperature of the nylon cage allows the transient temperature is higher than the recommended, but should not be higher than the recommended temperature 20 ℃, should be scattered in the long and short overtemperature low operating temperature, also note lubricant can bear the short overtemperature.
If run at constant temperatures above 120 ℃, it must use a metal cage bearing.
The nylon cage also shoulds not be used for -
The temperature of 40 ℃ the, because below this temperature, nylon loses elasticity.
At room temperature and contact time is short, generally for the rolling bearing of clean organic solvent such as white fuel-efficient, chloroform or dilute alkali solution will not affect the performance of the cage.
Refrigeration equipment used in the freon or ammonia for nylon erosion.
Under the condition of vacuum, due to dehydration, nylon cage will become fragile.
