Enable bearing lubricating base oil dance and strengths

In order to solve the high temperature, the community, general manager of the mechanical equipment, dust university, stained with water and vibration impact problem of product "lubricating base oil bearing.
1, the structure of the bearing is base bearing lubrication bearing is body sculpture, metal friction and orderly arrangement of development appropriate cavity sulfur added size, 2 molybdenum, such as composite lubrication in the base metal composite bearing made of solid lubricant friction covers an area of 25 to 65%. Solid piece of lubrication is based on 280 ℃ high temperature to work properly. But the lower mechanical strength ability is abate, contains the forehead deformation of metal ball groove can not inhibit the shortcomings and form of metal part is the function of lubricating base sculpture began lubrication effect. Based products for the shaft and the SKF Bearings http://www.fagbearings-hk.com/ lubrication is outstanding in the process of sliding friction lubrication part of the base material molecular axis of transfer on the metal surface of 1 / f, no small landfill surface formed a stable solid lubrication film brings a great deal of solid lubrication basis for shaft between the family and prevent grind buried tear. The reasonable combination of comprehensive) alloy and reducing nonmetallic grinding material perfecting their advantage good oil-free, high temperature, high film, low speed, control, national defense scour, jiang radioactive environmental movement and the water infiltration of the special lubricating base oil or other solution conditions were used in the work.
2, on the surface than carving lubrication occupy lubrication volume how many pieces and start the velocity and pressure intensity related operation speed is low. Bulk metal strength pressure should be bigger. Ingot as line walk based pieces of car wheel bearing lubrication is an area of about 25%, the attracting mechanism shaft bearing lubrication bearing, not high intensity of pressure in the lubricating base fragments of an area of about 65%.
Bushing 3, to the requirements of technology manufacturing, copper alloy bushing materials XuanRong must have high hardness, bushing, ordinary beard heat treatment, he also hrc45 at ease.
4 · lube base inlaid carved geometric shapes and request. Carved on the morphology of the product and the moment based size according to the two kinds of lubrication, adopted may not adopted the rectangle. In order to prevent what gong of the operation of the set must be is off.
5, breathing and gap measures of bushing congratulations line fragments of lubrication for about 10 times that of steel expansion coefficient. Changes in temperature, in order to adapt to the bearing, shaft and bushing at the beginning of estrangement of metal health with d4 (032, 0.5) dc4 / ~ 0.5%. 15. With the number of 0.5 mm. 45 to 0.7%. Mm. Friction lubrication fragments are bulging metal 0 bushing deputy party. 2 ~ 0.7%. Mm. This is bearing the initial period of operation guide sufficient lubrication slowly to reduce the consumption of the output power.
Six, oil-free lubrication bearing the basis of advantages:
A. No or less "lubricating base oil lubricating base oil or not applicable, cheer, it is hard not to use or less hydrating function of preserve one's health
Wear-resisting performance is good, b. Low friction coefficient of long service life.
C the right amount of 5%. Should be the most sexually plastic by force distribution in a large contact area, can improve the bearing capacity.
Wipe. D the government to eliminate degree coefficient of low almost ensure that flutters high precision work of the machinery.
E can reduce the cut, prevent pollution, noise, vibration machine, improve working conditions.
F. to protect personal safety in the forming process of start before the opening of the backbone of the mill no bite shaft phenomenon.
G. for light axis axis of grinding asked permission to the day of cooking, can be used to reduce the related parts of processing is not easy.
Thin. H wall structure, quality management, light, in order to minimize the mechanical size.
Bushing brass material. I can use the interface corrosion, used in the mass.
By aluminum casting enterprise practice opportunity bearing oil free base bearing for 15 straight months still use liner axis, run no more than common clearance, is expected to how to use pepper, compared to 12 months ahead the original service life (2 months). Shigeru lubricating base oil bearing aluminum ingot casting function in the appropriate motorists are not only safe, can be thought of as not adapt to the high oil, high temperature, film, low speed, control, national defense scour, jiang radioactive environmental movement and the water infiltration of the special lubricating base oil or other solution condition, equipment under the condition of the bearing is located in the vast value.
At present, the most bearings, needle roller bearing used in the machinery industry and so on, but small based bearing has been used in lubrication, gathered in the near future based bearing become the dominant bearing lubrication. "
Below is partly based bearing lubrication application features and benefits:
1, no or less "lubricating base oil lubricating base oil or not applicable, cheer, it is hard not to use or less hydrating function of preserve one's health
Wear-resisting 2, performance is good, the service life of the longest small coefficient of friction.
Plastic in 3, the right amount of the stress distribution in a large contact area, can improve the bearing capacity.
4, the static coefficient of friction can eliminate fluttered degree of low speed close to ensure the accuracy of the mechanical work outstanding.
5, the machine can reduce the cut, prevent pollution, noise, vibration, improve the working conditions.
6, formed in the process before the opening of the backbone of the grinding of the personal safety of protection no bite shaft phenomenon.
7, the hardness of axis of stone asked permission to handle axis during the day, will be tuning can be used to reduce the related parts and components processing is not easy.
8, thin-walled structure, quality control, light, in order to minimize the mechanical size.
9, the possibility of steel on the back of the plating a variety of metal, can be used in mass on dielectric decay; The goalkeeper position of the currently widely used all kinds of mechanical, such as: printing woven textile machinery, tobacco, machinery, micro-motor, automobiles, motorcycles and forestry machinery and so on.
