Brand:changbo
Model:N Series
N series Planetary gear units
Big size motors are suitable for connecting with gear boxes to reach rated power and the max torque. Low speed shaft and high speed shaft are able to run with heavy load.
Solid shaft with a flat key and a screw hole (Type≤353);
Solid shaft with two flat keys and three screw holes(Type≥354);
external splines shaft with location shaft shoulder
internal spline
Hollow shaft with power lock
Products and parts modularized;
Low speed bearing;
200-280-----double-row tapered roller bearing
353-695-----self-aligning roller bearing and deep groove ball bearing;
ductile iron case, thick wall and reinforcement
Mineral oil or synthetic oil lubrication, oil fill plug, oil window plug and drain plug
Gear stage
Coaxial type 1,2,3,4 stage planetary transmission
Angle 1 stage helical bevel gear combination 1,2,3 stage planetary transmission;
Materials: external gear 20CrMnTi
internal gear 42CrMo
cylindrical gear grinding
swimming planet carrier is a steel part
High speed and low speed shaft of coaxial and angle type are both able to rotate
deasil and anticlockwise
gear load capacity is checked and calculated by anti-pressure and transverse
rupture strength, maximum instantaneous power has passed validation. Motor introduction

break motor
IEC standard
Reinforced case has better rigidity to reduce break noise;
Direct current brake coil could be connected through rectifier module and also
could be connected with power directly
Braking torque is proportional to motor torque and it could adjust the clearance between brakepads;
Start frequently;
Fast and precise breaking;
Breaking motors are supplied without manual release lever, please note in the
contract if you need.
Manual release lever will reset automatically after releasing lever;
other instructions please refer to professional handbook or specification
Serve with transducer
Permissible frequency range of common motor: 20HZ-60HZ;
Break coil of breaking motor should be supplied power independently.
Usage for breaking motor special designed for variable frequency please refer to specification
