Pile machine decelerator with inverted motors, small-teeth-difference planetary gear and four ring plates
The invention relates to the technical field of pile machine decelerators, in particular to a pile machine decelerator with inverted motors, a small-teeth-difference planetary gear and four ring plates. The pile machine decelerator comprises a box body, two motors and a transmission component arranged in the box body. The pile machine decelerator is characterized in that the two motors are connected to positions under the box body in an inverted manner; a shaft stretching end of each of the two motors is connected with a NGW decelerator; the transmission component comprises eight eccentric bearings, the ring plates, inner gear rings and a planetary gear; the eight eccentric bearings are arranged on the output shaft stretching ends of the two NGW decelerators respectively; each eccentric bearing comprises a rolling bearing and an eccentric sleeve; according to the eccentric bearings, the phase difference between each first eccentric bearing and the corresponding second eccentric bearing, as well as each third eccentric bearing and the corresponding fourth eccentric bearing is 180 degrees, and the phase position of each second eccentric bearing is the same as that of the corresponding third eccentric bearing; each inner ring gear is arranged in the center of the corresponding ring plate; the planetary gear is connected with the neck of a main cylinder; the main cylinder is supported at the central inner hole of the box body by the first bearings and the second bearings; the main cylinder is connected with a drill stem flange. The pile machine decelerator has the benefits that (1) the pile machine decelerator is convenient to demount, repair and maintain; (2) the probability of overthrow accidents is reduced; (3) four-pole motors can be adopted for replacing six-pole motors, so that the cost and the weight are reduced, the service life of the eccentric bearings can be prolonged, and the ring plates do not vibrate.
