Abstract

The invention discloses a double-front end cover structure for a vertical installation motor. The structure includes a vertical motor, wherein the vertical motor is arranged in a tank, a main shaft ofthe vertical motor is vertically arranged on a first end cover, an outer side of the main shaft is provided with a stop-push bearing, an inner ring of the stop-push bearing presses against a retaining ring arranged on the main shaft, an outer ring of the stop-push bearing is connected with the first end cover, an internal portion of the first end cover is provided with a threaded groove hole, thefirst end cover further presses against a secondary cover, the secondary cover is provided with a circular hole at the threaded groove hole of the first end cover, a fixing bolt penetrates through the circular hole and is threaded in the threaded groove hole, and the secondary cover and the first end cover are threaded through a moving bolt. The structure is advantaged in that the secondary covercan be dismounted without separating the motor from abutting equipment to observe the bearing and grease conditions, whether dismounting maintenance is needed is then determined, and unnecessary dismounting is generally reduced.

Description

technical field [0001] The invention relates to the field of motors, in particular to an end cover structure of a vertical motor. Background technique [0002] Vertically installed motors have always been difficult to overhaul. Due to vertical installation, the front cover and bearings have to bear the weight of the entire rotor. After a long period of use, it is inevitable that the grease will deteriorate and even the bearings will be damaged. If the traditional single-layer end cover structure motor needs to be overhauled, the motor needs to be completely separated from the docking equipment, and then overhauled. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a double front-end cover structure of a vertically installed motor. [0004] The specific technical scheme is as follows: [0005] A double front-end cover structure for a vertically installed motor, including a vertical motor, the vertical motor is arrange...
