Abstract

The invention discloses a direct-current motor armature commutator dynamic pressure overspeed testing machine, and relates to devices for dynamic pressure overspeed tests after armature commutators of various direct-current motors of railway locomotives are assembled. The direct-current motor armature commutator dynamic pressure overspeed testing machine is mainly used for solving the problems that an existing vertical type overspeed machine is unstable in rotation, high in shock, high in equipment failure rate and low in efficiency when commutator high-speed overspeed experiments are carried out. According to the direct-current motor armature commutator dynamic pressure overspeed testing machine, a power output shaft is fixed on a double-support base through a bearing, the two ends of the power output shaft are connected with spigots of dummy shafts through flanges respectively, the other ends of the dummy shafts are fixed on double dummy shaft supporting points through bearings, constant-temperature overspeed boxes are symmetrically arranged on the two sides, in the axial direction, of the power output shaft, and the dummy shafts are arranged in the constant-temperature overspeed boxes respectively. The direct-current motor armature commutator dynamic pressure overspeed testing machine is convenient to operate, stable in shafting supporting and low in equipment failure rate, and can carry out overspeed tests on two commutators at the same time or one commutator.

Description

technical field [0001] The invention relates to the manufacturing industry of various direct current motors of railway locomotives, in particular to a commutator horizontal overspeed machine for a dynamic pressure overspeed test after the armature commutator of the direct current motor is assembled. Background technique [0002] At present, the known equipment for the dynamic pressure overspeed test after the armature commutator of the DC motor is assembled is a vertical or horizontal single output shaft, and its disadvantages are: ① the overspeed shaft has few supporting points and the rotation is unstable; High vibration and high failure rate; ③Short life of support bearings; ④Low overspeed efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiency, and provide a kind of dc motor armature commutator dynamic pressure overspeed testing machine with convenient installation, wide application range and high ov...
