Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] like figure 1 As shown, the present invention includes a housing, a backing plate 1, a bearing cover 2, a sealing ring 3, a J-shaped rubber sealing ring 4, a sealing ring 5, a mudguard tube 6 and a pressing plate 7. The main shaft of the motor is supported on the housing through bearings, and a bearing cover 2 is arranged outside the bearing, and the bearing cover 2 is sleeved on the main shaft of the motor, and the bearing cover 2 is fixedly connected with the housing. The inner end surface of the bearing cap 2 is provided with a positioning boss for axial positioning of the outer ring of the bearing. The backing plate 1 is annular and is arranged between the outer ring of the bearing and the positioning boss. The side wall of the inner hole of the bearing cover 2 is provided with a sealing groove, the sealing ring 3 is arranged in the sealing groove, and the...

Abstract

The invention discloses an electric locomotive spindle sealing structure for muddy water environment tunneling. The electric locomotive spindle sealing structure comprises a bearing cover, a sealing ring, a J-shaped rubber sealing ring, a pressing plate and a sealing ring; a motor spindle is supported on a shell through a bearing, the bearing cover is arranged on the outer side of the bearing, the motor spindle is sleeved with the bearing cover, and the bearing cover is fixedly connected with the shell; a sealing groove is formed in the side wall of an inner hole of the bearing cover, the sealing ring is arranged in the sealing groove, and the J-shaped sealing ring is located on the outer side of the sealing ring; and the pressing plate is fixedly installed on the bearing cover, and the pressing plate presses the J-shaped rubber sealing ring. The electric locomotive spindle sealing structure is provided with a mud blocking barrel, the mud blocking barrel and the sealing ring form a labyrinth sealing structure, and muddy water is prevented from splashing into the bearing. The electric locomotive spindle sealing structure is simple, low in cost, better in sealing effect and capable of effectively prolonging the service life of a motor.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a sealing structure for the main shaft of an electric locomotive used for excavation in a muddy water environment. Background technique [0002] The function of the sealing structure of the main shaft of the electric locomotive for excavation is to seal the water leakage between the rotating part and the fixed part of the electric locomotive. The quality of the sealing directly affects the stability and safe operation of the unit. Most of the existing sealing structures adopt a sealing ring for sealing. Although the structure is simple, the sealing performance is poor. [0003] The electric locomotive for excavation uses the motor as the power output source. When the electric locomotive is working in a muddy environment, the splashed muddy water will sometimes soak into the bearing of the motor from the gap between the motor shaft and the casing, which will easily cause damage to the equipm...
