Abstract

The invention discloses manufacturing and process of an efficient and durable TBM hobbing cutter. The efficient and durable TBM hobbing cutter comprises a heavy cutter shaft and an integral type tapered roller bearing, wherein the integral type tapered roller bearing is arranged on the outer side wall of the heavy cutter shaft, an upper oil seal end face support is arranged on the left side of the integral type tapered roller bearing, and a lower oil seal end face support is arranged on the right side of the upper oil seal end face support; an upper positioning end cover is arranged on the left side of the upper oil seal end face support. At present, a large number of phenomena of eccentric wear, tipping, cutter breakage, non-wear resistance and snap ring falling occur in tunneling of domestic and overseas TBM hobbing cutters, so that the hobbing cutters are replaced in advance, the waste is large, and engineering tunneling is seriously influenced; aiming at the current situations, the hobbing cutters are changed from related main components in material, structure and process, the performance of the related main components is substantially improved fundamentally, and meanwhile, the matching performance and systematicness of all parts are emphasized, so that the hobbing cutter is efficient and durable.

Description

Technical field [0001] TECHNICAL FIELD The present invention relates to apparatus, in particular a highly durable TBM cutters and manufacturing processes. Background technique [0002] As the state capital construction investment increase, the construction of large infrastructure projects and new infrastructure in the field of showing the continuity of growth, due to the TBM boring machine (TBM including) the construction of high performance and advanced, it is widely used in railway , tunnel road, water conservancy, urban rail transit projects, such as construction, and TBM (including shield) tool (mainly hob) is an important factor driving speed and cost of construction. At home and abroad TBM (including shield) in Excavation hob, large numbers of eccentric wear, chipping, cutting knife, clasp phenomenon, leading to premature tool change, seriously affecting the borer, but also increased the cost of excavation. In view of this, an efficient and durable TBM cutters manufacturing...
