PRODUCTION OF CYLINDER SLEEVE FOR INTERNAL COMBUSTION ENGINE

摘要

PURPOSE:To obtain the cylinder sleeve of high quality having sufficient stiffness by winding a high tensile wire rod spirally to casting body after reforming it in the coil shape of smaller diameter than the outer diameter of cylindrical casting body, then by brazing the both. CONSTITUTION:The annular recessed part 5 having the width W is provided on the outer peripheral face of the cylindrical casting body 3 made of cast iron and spiral guide groove 5a is machined on the bottom face of the recessed part 5. After the high tensile wire rod 4 the wind starting end of which is fixed to the cast body 3 being reformed in the coil shape having smaller diameter than the outer diameter of the cast body 3, it is wound spirally along the guide groove 5a. The wire rod 4 becomes the necessary cylinder sleeve 2 by being integrated with joining to the cast body 3 by brazing filler metal 6. The production of the cylinder sleeve of high quality having sufficient stiffness is thus enabled.
