SF-2 type oil storage pit storage rolling composite sleeve base, intermediate sintered bronze spherical powder to steel rolling, surface modified Polyoxymethylene (POM), and containing oil storage pit. The utility model is suitable for the place with low speed in the condition of normal temperature, replacing the traditional copper sleeve to reduce the cost and prolong the service life. The use of the rolling mill can save the oil filling frequency and simplify the replacement procedure.
Scope of application
The product has been widely used in automobile chassis, forging machine, metallurgical and mining machinery, engineering machinery, hydropower, steel industry and other fields
[main parameters]
Large bearing pressure: 70N/mm2
Friction coefficient: 0.05~0.25
Applicable temperature range: -40 DEG C ~130 C
High sliding speed: 2.5m/s
Allow high PV: 22N/mm2.m/s
Application characteristics:
1: in the case of less oil, the performance of more than other known boundary lubrication materials.
2: the friction surface is hard and thick, good wear resistance.
3: high mechanical strength, can withstand greater load tsk. The utility model is suitable for the rotary motion swing motion under the condition of high speed and low load, and is often used in the case of loading and unloading to open and close frequently and is not easy to form the fluid motion force lubrication.
4: in the boundary lubrication conditions can not be long-term maintenance, such as oil in the process of using a longer life.
5: the surface of the plastic layer in addition to a molding can be left a certain margin, assembly pressure into the hole after the self processing, in order to achieve better assembly size.
6: the surface of the wear-resistant layer of regular oil can be used as oil storage
