Abstract
The invention belongs to a dynamic lubricating grease adding device of a steel rail grinding wagon electric motor. The problem that an existing steel rail grinding wagon electric motor in working is required to shut down when lubricating grease is added, the work efficiency is low, the lubricating grease cannot completely enter a lubricating layer in a shut-down mode, and the bearing lubricating effect is poor is mainly solved. The dynamic lubricating grease adding device comprises a front end cover, a front inner bearing cover, a back end cover and a back inner bearing cover, wherein the front end cover and the front inner bearing cover are installed at the non-transmission end of the steel rail grinding wagon electric motor, and the back end cover and the back inner bearing cover are installed at the transmission end of the electric motor. The dynamic lubricating grease adding device is characterized in that the front end cover and the front inner bearing cover are respectively provided with labyrinths, and the back end cover and the back inner bearing cover are respectively provided with labyrinths. The lubricating grease and a rotary shaft are isolated through the labyrinths of the front end cover, the back end cover, the front inner bearing cover and the back inner bearing cover, the lubricating grease can be dynamically added without shut-down, and the work efficiency is improved. Due to the fact that the lubricating grease is added in the labyrinths, the lubricating grease can completely enter the lubricating layer, and the bearing lubricating effect is good.
Description
Technical field
The present invention relates to the grease-added device of a kind of steel rail grinding tramcar motor, relate to specifically dynamically grease-added device of a steel rail grinding tramcar motor.
Background technology
At present, need shut down grease-addedly when known steel rail grinding vehicle electric motivation is grease-added, its shortcoming is
Want grease-added during working condition and just must shut down, inefficiency; Shut down grease-addedly, lubricating grease can not enter lubricating layer fully, and the bearing lubrication effect is bad.
Summary of the invention
The objective of the invention is need not shut down and provide a kind of in order to overcome above-mentioned deficiency, lubricating grease can enter lubricating layer fully, the dynamic grease-added device of steel rail grinding tramcar motor that bearing lubrication is effective.
Technical solution of the present invention is: the dynamic grease-added device of steel rail grinding tramcar motor, comprise the front end housing and the front inside cap that are arranged on steel rail grinding tramcar motor non-transmision end, and be arranged on rear end cap and rear inside cap on the electric-motor drive end, it is characterized in that: be respectively equipped with the labyrinth on front end housing and front inside cap, be respectively equipped with the labyrinth on rear end cap and rear inside cap.
Labyrinth on front end housing described in technical solution of the present invention and front inside cap is respectively equipped with the side of front end bearing; Labyrinth on described rear end cap and rear inside cap is located at respectively the side of rear end bearing.
The present invention is at forward and backward end cap and the forward and backward inside cap in steel rail grinding tramcar motor mounting strap labyrinth, labyrinth by forward and backward end cap and forward and backward inside cap isolates lubricating grease and rotating shaft, when the steel rail grinding tramcar motor runs up, in the labyrinth, lubricating grease remains static, so it is grease-added to need not to shut down capable of dynamic, has improved operating efficiency; The motor High Rotation Speed, in time grease-added in the labyrinth simultaneously, can make lubricating grease all enter the bearing lubrication layer, and bearing lubrication is effective.
