What is a sleeve
The bearing pad is equivalent to the outer ring of the sliding
bearing. The bushing is integral and the relative shaft is moving. The
bearing pad is divided and the shaft is rotated.
Journal: the part of the constituent shaft supported by the bearing;
Bearings: Parts that match the journal;
Bushing: Made of a full cylindrical sleeve.
In the LEGO Mindstorms series and the BioTrans RoSys series of robot
components, the shaft sleeves are specified by the silver-grey LEGO
standard shaft retainers, which are available in full shaft sleeves and
1/2 shaft sleeves.
Bushing material
Plastic
sleeve specifications: POM polyformaldehyde plastic sleeve, PA nylon
plastic sleeve, PTFE PTFE plastic sleeve, Teflon plastic sleeve, Teflon
plastic sleeve. Characteristics
of plastic bushings: acid, alkali, corrosion, mechanical strength, good
wear resistance, heat resistance, oil resistance and chemical
resistance. Plastic sleeves are available in PTFE/Teflon/Teflon/PTFE, Polyoxymethylene POM, Nylon PA, Polypropylene PP. Products for aerospace, automotive, sensors, medical, pharmaceutical,
satellite, valves, pumps, sanitary, electronics, bearings, electrical
appliances, and other industries.
Bi-metal bushing part material is a patented product and it is a new material for profiled and standardized bushing products. Mainly
for the various shaft sleeve processing companies and general machinery
factories and machinery repair and other companies, to provide bimetal
sleeve parts near-net shape material (Near Net Shape Material). With this bimetal bushing part-shaped material, a very small amount of
machining (such as chamfering, drilling, car or oil tank) can be used
as a bushing product for direct installation.
Copper sleeve in the role of machinery?
Fixed
When
the gear shaft is moving, try not to let the direction of the gear
shaft be shifted due to vibration. At this time, it is necessary to use a
copper bushing to help fix it. The most important role of the copper sleeve in the machine is the
fixed position, which is all the properties of the copper sleeve.
2. Sliding bearing
This is another role that the copper bushing plays in the machinery. In
order to reduce expenses and save costs, sliding bearings are needed at
this time, and copper bushings have exactly this function. It
is mainly based on the axial direction of the bearing to design the
thickness of the sleeve bearing sleeve, and in fact the copper shaft
sleeve is a kind of sliding bearing. When the mechanical rotation is
relatively low and the clearance requirements are relatively high, the
environment can be used. Copper bushings are used instead of rolling bearings to operate. Copper bushings are wear-resistant and can be used for a long time, so to a large extent this can help them save money.
Copper bushings are mainly used in what areas?
The
copper bush on the shaft acts as a bearing and belongs to the class of
sliding bearings. It is a bearing that works under sliding friction. The
shaft is rotating relative to the shaft and generally requires the
assistance of a lubrication system. Slide bearings work smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is
separated by lubricating oil without direct contact, friction loss and
surface wear can be greatly reduced, and the oil film also has certain
vibration absorption capability
The role is lubrication, heat dissipation, friction reduction, extended life and so on.
Copper
jacket is mainly used in machinery, printing and dyeing, papermaking,
chemical, aerospace, coal, petroleum, automotive, construction
machinery, metallurgical and other industries.
