Description
Technical field
This utility model relates to a kind of electricity for the vertical structure threephase asynchronous without bearing internal external lid arrangement
Shaft seal structure, this utility model especially relates to a kind of flange end cap axle sealing structure that can be the most waterproof.
Background technology
For the vertical structure threephase asynchronous without bearing internal external lid arrangement, axle stretch end fills flange end cap 1, and electric
Axle through portion between arbor 2 and flange end cap is matched in clearance, is convex as vertical machine for waterproof conventional measure
Load onto a V-packing ring 5 on acies lid, but when motor is vertical install time, particularly upwards install on axle, due to drive equipment and
The reason of environment, can form hydrops at the groove at flange end cap 1, and water can permeate V-packing ring 5, enters motor internal along axle,
Cause motor entering water, damage motor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of hydrops that can will produce in time
Discharge, simple in construction and easy for installation can be the most waterproof flange end cap axle sealing structure.
According to this utility model provide technical scheme, described can be the most waterproof flange end cap axle sealing structure, including
Flange end cap, motor shaft, ring packing dish and outside framework oil seal；Motor shaft it is rotatablely equipped with, at flange end cap in flange end cap
Outer end, inner circle position be provided with annular boss, in annular boss, be provided with outside framework oil seal, at the electricity of corresponding annular boss position
Be provided with ring packing dish on arbor in interference fit, the dish of ring packing dish is along entangling annular boss partly, ring packing
It is matched in clearance between dish and the annular boss of flange end cap, the flange end cap outside corresponding annular boss cylindrical has ring
Connected in star.
The bottom surface of described annular groove offers osculum, the axis of osculum becomes 10 with the bottom surface of annular groove ~
The angle of 20 °.
The axis of described osculum becomes the angle of 15 ° with the bottom surface of annular groove.
Ring packing dish in this utility model operationally rotates with motor shaft, can be close along annular by hydrops
Closing disk throws away, and water can be discharged by osculum effectively, will not form hydrops in flange end cap groove.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
This can be the most waterproof flange end cap axle sealing structure, including flange end cap 1, motor shaft 2, ring packing dish 3 with
Outside framework oil seal 4；In flange end cap 1, it is rotatablely equipped with motor shaft 1, is provided with annular in the outer end, inner circle position of flange end cap 1
Boss 1.1, is provided with outside framework oil seal 4 in annular boss 1.1, joins in interference on the motor shaft 1 of corresponding annular boss 1.1 position
Conjunction is provided with ring packing dish 3, and the dish of ring packing dish 3 is along entangling annular boss 1.1 partly, ring packing dish 3 and flange
It is matched in clearance between the annular boss 1.1 of end cap 1, the flange end cap 1 outside corresponding annular boss 1.1 cylindrical has ring
Connected in star.
The bottom surface of described annular groove offers osculum 1.2, the axis of osculum 1.2 and the bottom surface of annular groove
Become the angle of 10 ~ 20 °.
The described axis of osculum 1.2 becomes the angle of 15 ° with the bottom surface of annular groove.
In this utility model, ring packing dish 3 and motor shaft 2 use hot jacket mode to install.Ring packing dish 3 one aspect can
So that outside framework oil seal 4 is carried out axial limiting, on the other hand, utilize the centrifugal force of ring packing dish 3, hydrops is outwards thrown away.Get rid of
The hydrops gone out has and is partially left in annular groove.Owing to offering osculum 1.2 on the bottom surface of described annular groove, permissible
Effectively the hydrops in annular groove is discharged, hydrops will not be formed in the annular groove of flange end cap again, protect motor, it is to avoid
Motor is impaired.
