Bracket for rotating electrical machine

Abstract

Abstract PURPOSE:To improve costs and productivity by avoiding the use of casting items by forming a bracket after pressing and moulding a steel plate wherein a flange section having a flange surface is formed by pressing and moulding the steel plate and the flange section is adhered to a bracket section. CONSTITUTION:A steel plate is pressed and moulded and a bracket section 30 is made by unitedly forming a bearing support section 23, a closure section 17 and ventilation holes 9. Similarly, the steel plate is pressed and moulded and a flange section 30 having contact sections 32 is formed wherein the contact sections are made by pushing the steel plate forward the bracket side after leaving the surrounding flange surface 24. Ventilation flues 35 are formed by producing several concave places 34 at a part of the contact sections and a bracket at load side is also formed by providing coupling holes 36 and by combining with the bracket section 30. In this way, no casting items are used for the bracket at the load side. Therefore, costs will be reduced and productivity will be raised.
