Abstract
A bearing section waterproof structure of a vertical motor formed in a semi-permanent seal structure by a non-contact seal of labyrinth structure, enabling the extension of maintenance intervals by abolishing consumable parts, and enabling a reduction in weight and size. The structure comprises a vertical motor shaft, bearings supporting the shaft, a bearing cover storing the bearings, a bearing retainer fitted to the outer peripheral surface of the shaft and holding the bearings, and a bearing bracket holding the outer peripheral surfaces of the bearings and having the bearing cover. The portion of the bearing cover in proximity to the bearing retainer is formed in the labyrinth structure, the portion of the bearing retainer in proximity to the bearing cover is formed in the labyrinth structure, and a drain groove is formed in the axial upper surface part of the bearing bracket so as to be positioned under the labyrinth part of the bearing cover.
Description
Technical field
The present invention relates to a kind of bearing section waterproof structure that on upright installing type motor, adopts.
Background technology
The bearing section waterproof structure of existing vertical type motor is to use contact seal circle (for example, with reference to patent documentation 1) between the support of bearing and rotating shaft.In addition, use also having of non-contacting seal.
Below with Fig. 3 first prior art is described, with Fig. 4 second prior art is described.
First prior art:
Among Fig. 3, in a side of the cylindrical bearing lining 4 of the support of bearing 10 by the rotation of bearing 1 supporting rotating shaft 2 and its central part, the bearing (ball) cover 11 that surrounds bearing 1 side is installed, its central part upper end is equipped with contact seal circle 12.The part of contact seal circle 12 contacts with rotating shaft 2 outer peripheral faces, prevents the outflow of the lubricating grease or the lubricating oil of lubricating bearings 1 by the contact site sliding friction of contact seal circle 12 and rotating shaft 2, and also prevents entering of outside liquid and solid.
Second prior art:
Among Fig. 4,, the bearing (ball) cover 5 that surrounds bearing 1 side is installed, and the bearing seal 6 that keeps bearing 1 is installed at rotating shaft 2 outer peripheral faces in a side of the cylindrical bearing lining 4 of the support of bearing 10 by the rotation of bearing 1 supporting rotating shaft 2 and its central part.Bearing (ball) cover 5 and bearing seal 6 near opposite position, by forming non-contacting seal with labyrinth type (labyrinth) structure, thereby prevent the outflow of the lubricating grease or the lubricating oil of lubricating bearings 1, and also prevent entering of outside liquid and solid.
[patent documentation 1] Japanese kokai publication hei 5-161297 communique
Yet there is following problem in the bearing section waterproof structure of this existing vertical type motor.
(1) friction because of contact seal part sliding part causes loss, in addition, because abrasion, wearing and tearing, the deterioration of sliding part cause sealing to reduce, needs periodic replacement contact seal part.
(2), cause from outside inflow liquid or solid because abrasion, wearing and tearing, the deterioration of sliding part cause sealing to reduce.
(3) on its structure, in case of surpassing the situation of the above liquid measure of tolerance, there is the hidden danger of influent in the non-contacting seal of labyrinth type (labyrinth) structure.
(4) if increase the tolerance of the non-contacting seal of labyrinth type (labyrinth) structure, then maze-type structure will increase and become complicated, hinder the lightness and the miniaturization of vertical type motor.
The present invention develops for addressing the above problem, its objective is, a kind of bearing section waterproof structure of vertical type motor is provided, the non-contacting seal that utilizes labyrinth type (labyrinth) structure is as the semipermanent hermetically-sealed construction, by banning expendable parts, can prolong maintenance cycle, realize lightness, miniaturization.
Summary of the invention
For addressing the above problem, the present invention is: a kind of bearing bilge construction of vertical type motor, it comprises the rotating shaft of vertical type motor, support the bearing of described rotating shaft, the bearing (ball) cover that holds described bearing, be installed in described rotating shaft outer peripheral face and keep the bearing seal of described bearing, keep the outer peripheral face of described bearing and be provided with the support of bearing of described bearing (ball) cover, the approaching described bearing seal place of described bearing (ball) cover is labyrinth type (labyrinth) structure, the approaching described bearing (ball) cover place of described bearing seal is labyrinth type (labyrinth) structure, and the described support of bearing axially on facial and labyrinth type (labyrinth) structure below that be positioned at described bearing (ball) cover establish rhone.
The bearing section waterproof structure of vertical type motor according to the present invention, the vertical type motor upside support of bearing and the liquid above the bearing portion are discharged into the motor outer circumferential side by the rhone above the support of bearing, thereby realize adopting non-contacting seal to prevent the inflow of liquid, and can be by easy labyrinth type (labyrinth) structure, reach the miniaturization of vertical type motor, the lightness effect.
