THE SLEEVE ON THE SUSPENSION

LINER HANGERTo improve the performance of micro-motors, internal combustion modelers increasingly use parts from non-ferrous metals. For example, the cylinder liner can be made of brass, and the piston is of aluminum alloy. To such a pair worked better, mirror shells coated with a layer of chromium.

On the Republican syut in Alma-ATA, chrome plated cylinder liners of engines with a working volume of 2.5 cm3 with a special suspension, which greatly facilitates the time-consuming process.
 
The suspension itself consists of an ebonite body with a groove in the lower part under the flange of the sleeve. Top in detail on epoxy glue is inserted into lead terminal is the anode. Around it are drilled 8 holes Ø 2 mm, which are used to drain from the internal cavities of the hydrogen generated in the chrome plating process. There is also a ebony cover: between it and the housing is brass ring is the cathode. Cover drawn by three M3 bolts.
Pendant chrome
 
Suspension for chrome plating of cylinder liners motors:
 
1 — anode, 2 — body, 3 — ring-cathode, 4 — bolt M3, 5 — cover, 6 — the cartridge.

TECHNOLOGY FOR CHROME PLATING OF CYLINDER LINERS OF MICROMOTORS WITH PENDANTS
 
Chromium plating shall be done only under the hood in a fume hood.
 
Typically, the thickness of the deposited chromium is about 0.025 mm. So before the chrome plating, it is necessary to increase the magnitude of the inner diameter of the sleeve. The parts that shall be subjected to chromium plating, it is necessary to cover tsaponlakom.
