Special cutting power head design with 200~ 400mm diameter inner wall drill
Abstract：the design content is to design special cutting power head with 200~ 400mm diameter inner wall drill. It provides a power device embedded in the lathe machining bearing wall has a blind hole. This article comprehensive disadvantages and purpose of the study, use and other aspects of the inner wall of drilling device for power head of the new. The design of the main components, including pulley design calculation, structural design of shaft, bearing selection, design calculation, wheel bearing life calculation. Then in the design of transmission scheme on considering the simplicity of transmission, flexibility and practicability of the scheme as a final solution of the design. The overall design of the existing drilling head on the basis of further improvement, simple structure, reliable transmission, small size, good performance,compact structure, low equipment cost, safe operation, convenient operation, convenient repair and management.
Key Words: drilling head lathe Embedded bearing Special cutting power head drill barrel inner wall Calculation
