The invention provides a rope sheave of a hoisting machine for an elevator and the hoisting machine for the elevator, which can omit reaming and drilling at the same time and can transmit torque more reliably. The rope sheave of the elevator hoisting machine is provided with a hub part (31), a groove part (40) is formed in the surface of the hub part, the groove part is provided with a first side wall surface (40a), a second side wall surface (40b) and a bottom surface (40c), a first through hole (41) for a hinge pin (50) to be inserted is formed in the bottom surface, and the rope sheave of the elevator hoisting machine is further provided with a first inclined seat (61) arranged between the hinge pin and the first side wall surface and a second inclined seat (62) arranged between the hinge pin and the second side wall surface. And a second inclined seat (62) provided between the hinge pin and the second side wall surface, the first inclined seat having a first inclined surface (61a) and a first facing surface (61b) in which a first arc groove (61c) is formed, and the second inclined seat having a second inclined surface (62a) and a second facing surface (62b) in which a second arc groove (62c) is formed.

    本发明提供电梯用曳引机的绳轮以及电梯用曳引机,其能够省略铰孔的同时开孔加工,并且能够更可靠地传递转矩。电梯用曳引机的绳轮具备毂部(31),在毂部的表面形成有槽部(40),槽部具有第1侧壁面(40a)、第2侧壁面(40b)和底面(40c),在底面形成有供铰销(50)插入的第1贯通孔(41),电梯用曳引机的绳轮还具备:第1倾斜座(61),其设置于铰销与第1侧壁面之间;以及第2倾斜座(62),其设置于铰销与第2侧壁面之间,第1倾斜座具有第1倾斜面(61a)和第1相对面(61b),在第1相对面形成有第1圆弧槽(61c),第2倾斜座具有第2倾斜面(62a)和第2相对面(62b),在第2相对面形成有第2圆弧槽(62c)。
