Planetary hypocycloid two-ring-sheet pile machine speed reducer with inverted motors
The invention relates to the technical field of pile machine speed reduction, in particular to a planetary hypocycloid two-ring-sheet pile machine speed reducer with inverted motors. The speed reducer comprises a case, the motors and a transmission part arranged in the case. The speed reducer is characterized in that the two motors are inversely connected to the lower portion of the case, and the terminal ends of two motor shafts are connected with NGW reducer bodies; the transmission part comprises eccentric bearings, ring sheets, hypocycloid gear rings and cycloidal gears, wherein the four eccentric bearings are arranged on output shaft extending portions of the two NGW reducer bodies respectively; each eccentric bearing comprises a rolling bearing and an eccentric bushing, and the phase difference between the first eccentric bearing and the second eccentric bearing is 180 degrees; the hypocycloid gear rings are assembled at the centers of the ring sheets, and the cycloidal gears are connected with the neck of a main barrel; the main barrel is supported on a circular inner hole in the center of the case through the first bearing and the second bearing and connected with a drill rod flange. The planetary hypocycloid two-ring-sheet pile machine speed reducer with the inverted motors has the beneficial effects that (1) dismounting, repairing and maintaining are convenient; (2) the tipping accident is reduced due to lowering of the gravity center; and (3) an original six-pole motor can be replaced by a four-pole motor, the cost and the weight are reduced, the theoretical service lives of the eccentric bearings can be prolonged, and the ring sheets are free of vibration.
