The holder. The bearing cage, also called bearing retainer, finger wrapped in entire or in element, part of the rolling body, bearing parts and move with it, are applied to isolate the rolling physique, typically also led the rolling physique and will retain it in the bearing.
Material Science.
Inside the work of rolling bearing, the sliding friction caused by bearing heat and put on, specifically in high temperature operating circumstances, the centrifugal force intensifies the friction, put on and fever, serious when can cause the holder burns or fracture, resulting in bearing New desgin cable tray doesn't work. Retainer, needs of cage components has specific strength, also have very good thermal conductivity and smaller friction coefficient, very good wear resistance, effect toughness and low density and linear expansion coefficient as well as the rolling body is close to. In addition, stamping cage to be subjected to stamping complex deformation, but in addition the needs of the material has great processing properties. In some demanding cage above and a few will probably be via a layer of silver.
Preserve variety frame material: low carbon steel / stainless steel cage, bakelite / plastic (nylon) holder, brass / bronze / aluminum alloy holder etc..
The production technique of classification:
1, die holder
Die casting preserve raw material frame for aluminum alloy, brass, die material melted and poured into the die casting machine, a holder of die casting. Casting gate on the lathe. Procedure capabilities of this party is:
(1) the holder directly casting molding, can acquire the geometry and dimensional accuracy, with out the want for mechanical processing, higher production efficiency.
(two) die casting, metal solidification, microstructure and put on resistance of precision, great surface quality.
(3) a higher material utilization, decrease charges.
However the die casting aluminum alloy cage, have to have big tonnage equipment, mold design and style and manufacturing complex, die casting can effortlessly make the retainer pocket hole strain. Inside the bearing influence, vibration and speed altering circumstances, the really need to additional boost the top quality of die holder.
two, plastic manufacturing cage casting approach
The engineering plastics in the barrel vacuum drying granular, the resistance wire heating melt into a semi ?C liquid state, using the aid from the plunger or screw compression,Cable tray bend tee cross the semi liquid material in the nozzle in to the injection molding machine mould, immediately after heat preservation, soon after cooling to receive the holder desires. Course of action characteristics of his:
(1) the holder a plastic injection molding, can acquire the accurate geometry and dimensional precision and low surface roughness value, without having the need to have for mechanical processing, higher production efficiency.
(2) die casting and plastic bearing assembly is practical, Slotted channel, easy to understand automation control.
(three) the plastic holder is wear resistant, antimagnetic and low friction and superior efficiency.
However the disadvantage of plastic itself exists thermal deformation, aging and brittle fracture, plus the cage structure and plastic injection method on some problems, that are castaluminium cable tray cage restricts the application of.
