FIELD: mechanical engineering.
SUBSTANCE: method comprises making the members of insert of a wood to form sectors whose cross-sections are shaped into trapeziums, assembling the ring blank from the sectors, and working the surface. Before making the insert, the wood is damped up to 75-80%, and heat conducting members are embedded into the wood member. Subsequent to making the sectors, the wood member is modified, pressed, and dried down to 1-2%.
EFFECT: prolonged service life.
