Online steel rail trimming device with planar secondary enveloping toroidal worm speed reducing mechanism

WANG LEI / HAN SHUANGPING / XU CHUNTAO

The invention relates to an online steel rail trimming device with a planar secondary enveloping toroidal worm speed reducing mechanism. The device comprises a driving motor (1), a spindle box body (5) and a base plate (9), wherein the spindle box body (5) is connected with the base plate (9) through a positioning sliding shoe (6); a spindle (7) and a planar secondary enveloping toroidal worm transmission pair are arranged in the spindle box body (5); the planar secondary enveloping worm transmission pair comprises a planar secondary enveloping worm (4) and a turbine (8), the planar secondaryenveloping worm (4) is located below the turbine (8) and meshed with the turbine (8), the planar secondary enveloping worm (4) is connected with the driving motor (1), the turbine (8) is connected with the spindle (7), and the circumferential milling disc (3) is mounted at one end of the spindle (7). Online trimming of the steel rail is achieved through the planar secondary enveloping toroidal worm transmission pair, and the device has the technical advantages of being compact in structure, large in speed ratio, high in efficiency, small in size, light in weight and stable in operation.
