Реанимация токарного станка 16Б16КА, начало. Ремонт основного электродвигателя. Не так всё просто.

This video series will be about the restoration of one of the best lathes of the Soviet era, and even today. I'll show you what anyone might encounter when buying such a machine inexpensively. First comes the main electric motor, followed by other important parts. The machine is 37 years old and has seen a lot of abuse, so there's a lot of work ahead, and for a perfectionist, that's a whole lot of work. The video [Resuscitation of a 16B16KA Lathe, Beginning. Repairing the Main Electric Motor. Not So Simple.] (https://studio.youtube.com/video/KVSp...) shows in detail the maintenance and repair process for this motor. Here are the key points and characteristics we were able to determine: Engine Specifications During cleaning, it was discovered that the motor was a two-speed motor, and its power ratings were lower than originally expected: *1st speed:* 720 rpm, power **3.2 kW**. *2nd speed:* 1440 rpm, power **5.3 kW**. This discovery pleased the author, as the 7 kW model is now sufficient for operation via the frequency converter, instead of the 11 kW model. Repair and Maintenance 1. *Cleaning:* The engine was heavily contaminated with oil and dirt, which interfered with cooling. The author washed it with regular gasoline, after which the housing looked like new. 2. *Bearings:* *Rear bearing:* After cleaning, the original GPZ bearing (which had been in use for 37 years) turned out to be in better condition than the new Chinese replacements that arrived. The author decided to keep it, packing it with fresh grease (he used high-quality Litol with a fill rate of about 50%). *Front bearing (near the pulley):* It turned out to be more worn and had to be replaced with a new one. 3. *Removing the pulley:* This turned out to be the most difficult part ("a real quest"). A standard three-jaw puller failed and began to deform the cast-iron pulley. *Solution:* The author made a special device—a heavy-duty steel clamp made of two halves that fits snugly into the pulley groove. Using this device and a 5-ton jack, the pulley was pulled off without damaging it. The engine interior was in perfect condition—the windings were dry, the varnish was shiny, and no traces of oil were found inside the housing. The engine has now been fully serviced, assembled, and is ready for installation on the machine. #machinerestoration #workshopathome #electricmotor
