DC traction gear motor package: two tons --- 30 tons flat car battery car with DC traction gear motor, 1.5kw - 7.5kw, can add brake assembly supporting the governor, the governor reversing cycloid reducer Structure: is a use of cycloid gear meshing planetary gear transmission principle models, is an ideal gear, has many advantages, versatility, and reverse operation. Main features: 1, the use of reliable, long life: because the main components is the use of high-carbon steel quenching treatment (HRC58-62), and then grinding together, and the cycloid pin gear teeth meshing sets delivered to the formation of needle teeth rolling friction pay, friction coefficient is small, so that the engagement area without sliding, wear minimal, so durable. 2, reduction ratio, high efficiency: a gear reduction ratio of 9 to 87, two-stage gear reduction ratio of 121 to 5133, a multi-stage combination of up to tens of thousands, and the Department of needle teeth meshing nested rolling friction surface without engagement sliding, so a slowdown efficiency of 94%. 3, smooth operation, low noise: in operation at the same time for a few more teeth in contact, coincidence degree, smooth operation, overload, low vibration and noise, noise small variety of models. 4, compact, small size: Compared with the same power of other gear, weight, small size 1/3, as is the planetary transmission input shaft and the output shaft on the same axis, in order to obtain the smallest possible size. Motor type: DC series motor reducer type: cycloid machine motor voltage: 24V, 36V, 48V, 72V motor power: 1.5KW, 2.2KW, 3KW, 4KW, 5.5KW, 7KW, 7.5KW motor speed: 1500RPM, 3000RPM (plus gear is recommended to use 1500RPM) gear reduction ratio: 9,11,17,23,29,35,43,59,71,87
