Gear Cutting Tools

Particular Solution of Cutting Tool Path Applied on Helical Surface with Circular Profile

“…In the helical surface shaping process, the coordinate systems uvt and X  move, while not changing their relative position. As, at the initial moment, they coincided with the systems UVT and X, respectively, then the transition between them is also described by the matrix (11). The relative helical motion of the tool and the machined surface, as described by the relative displacement of the coordinate systems X  and X, can be described by the displacement vector and the matrix of rotation - Fig.…”

“…The machining of heat treated materials by milling is intensively developing, which is driven by economical (for replacement of grinding process with machining) and ecological (easy chip removal) considerations [8,9,10]. The specificity of hobbing results in the axial profile of the cone-derivative helical surface not being rectilinear [11,12,13], which makes the verification of worm machining accuracy difficult. Worm wheel machining hobs to be mating with the cone-derivative worm in the worm gear, on the other hand, are geometrically complex and technologically difficult to execute [14,15].…”

Development of the low backlash planetary gearbox for humanoid robots

“…With this type of gears, low backlash is obtained and maintained in a very simple manner, while the machining process, which is described in [11], [12], can be easily performed on standard gear manufacturing machinery. In the following chapters, the concept of a low backlash planetary gearbox with taper gears is considered.…”

Machining of Spur Gears Using a Special Milling Cutter

“…The durability and good operating conditions of the toothed gears are largely influenced by the manufacturing accuracy and the structure and roughness of the cooperating surfaces [1][2][3]. These gears are manufactured using many profiling and hobbing methods [4][5][6][7]. They are machined chiefly by the hobbing method with modular hobs or Fellows cutters, or by gear shaving by the MAAG or Sunderland method - Fig.…”
