Description
Technical field
The utility model relates to the strand grinding machine of Power Machines technical field, particularly twists the structure of the retarder of grinding machine.
Background technique
Existing strand grinding machine mainly comprises frame, power plant, clutch, speed changer, retarder and mill tube, power plant are arranged in frame, the output shaft of power plant and the input shaft of speed changer are by belt pulley and belt transmission, the input shaft of speed changer connects clutch, the output shaft connection reducer of speed changer, the output shaft of retarder connects mill tube.This structure does not use planetary reducer, unreasonable due to structure, and velocity ratio is little, structure is not compact, volume large, from the feature such as heavy, working life is short.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides involute one planetary gear speed reducer of the maneuvering milling machine that a kind of velocity ratio is large.
The purpose of this utility model is achieved in that involute one planetary gear speed reducer of maneuvering milling machine, comprises housing, internal gear, eccentric shaft, the first row star-wheel, the second planet wheel, reducer output shaft; Described internal gear is arranged in housing; Described eccentric shaft comprises the eccentric shaft body, the first eccentric boss, the second eccentric boss that are wholely set, first eccentric boss and the second eccentric boss are eccentrically set on eccentric shaft body, the axis of the first eccentric boss and axis line centered by the axis of eccentric shaft body of the second eccentric boss are arranged symmetrically with, and one end of eccentric shaft body is supported on housing; Described first planet gear is connected on the first eccentric boss, and the second planetary pinion is connected on the second eccentric boss, and the first row star-wheel and the second planet wheel are all arranged on the inner side of internal gear and are all meshed with the internal tooth of internal gear; Described reducer output shaft comprises the output shaft body and disk that are wholely set, output shaft body and eccentric shaft body coaxially arranged, the other end of eccentric shaft body is supported in output shaft, one end of output shaft body is supported in housing, the other end stretches out housing and is supported in the frame of described strand grinding machine, disk along the circumferential direction connects multiple bearing pin, every root bearing pin is all set on the first row star-wheel and the second planet wheel, and the mill tube of described strand grinding machine is connected on the output shaft body of reducer output shaft.
Eccentric shaft of the present utility model, as input shaft, is connected with the output shaft of speed changer, drives first planet gear, the second planetary gear rotation, drives the disk rotational of output shaft, drives output shaft body to rotate, thus drives mill tube to rotate.Involute one planetary gear speed reducer has that velocity ratio is large, compact structure, volume are little, from the feature such as heavy and light, long service life.
For the ease of installation and removal, described housing comprises the first end cap, the second end cap, and the first end cap, the second end cap are bolted.
In order to prevent bearing pin from wearing and tearing, every root bearing pin is all nested with guide, and the guide that only need more renew during wearing and tearing can protect bearing pin.
