Abstract
The present utility model discloses a vertical type motor sealing structure. In the structure, a blocking disk is arranged on a part of a motor main shaft, which is stretched out of a motor shell body, and the blocking disk is rotated with the motor main shaft. When the blocking disk of the sealing structure is rotated with the motor main shaft, rain water, oil stain or dust are thrown out of the motor shell body through the centrifugal force effect, a sealing ring is also rotated with the motor main shaft, the original relative friction movable sealing is changed into static sealing, thus wearing caused by friction of the sealing structure can be avoided, rain water, oil stain or dust can be effectively prevented from entering into the motor shell, normal operation of the motor can be reliably guaranteed, the motor can be prevented from being damaged, and service life of the motor can be prolonged. Moreover, the sealing structure is simple to use, low in costs and obvious in beneficial effects.
Description
Technical field
The utility model belongs to technical field of motors, particularly a kind of vertical machine hermetically-sealed construction.
Background technology
The mode that vertical machine generally adopts motor shaft shaft extension end to make progress connects supporting with working machine, the sealing of its shaft extension end mostly is that the matching part at end cap and motor shaft adds drag seal.But; Especially in the open the motor of installing and using in the environment; Because factor affecting such as aging, the wearing and tearing of the high speed rotating of motor shaft and sealing ring, rainwater, greasy dirt and dust are easy to got in the electric machine casing by sealing circle and end cap connecting bolt position, cause the corrosion of the premature wear and the stator winding coil covering of motor shaft; Cause the operating failure rate of motor to increase, even motor integral body is scrapped.
The utility model content
It is reliable that the purpose of the utility model provides a kind of sealing property, can guarantee the normal operation of motor effectively, the vertical machine hermetically-sealed construction of avoiding equipment breakdown to take place.
The technical scheme that the purpose of realization the utility model is taked is: a kind of vertical machine hermetically-sealed construction, and the position of stretching out electric machine casing at electric machine main shaft is coated with block plate, and this block plate rotates with electric machine main shaft.
The position that said electric machine main shaft stretches out electric machine casing also is coated with sealing ring, and the sealing ring rotates with electric machine main shaft.
Said block plate is connected with the electric machine main shaft close-fitting.
Said block plate is a disk structure, and its diameter is equal to or greater than the diameter of shaft extension end enclosing cover.
The vertical machine hermetically-sealed construction of the utility model; The block plate that is provided with is in the process with the electric machine main shaft rotation; To drop on top rainwater, greasy dirt or dust by its centrifugal action and get rid of to the space beyond the electric machine casing, sealing ring also rotates together by original relative friction movable sealing with electric machine main shaft and becomes static seal simultaneously, has avoided the wearing and tearing after containment member rubs thus; Thereby prevent that effectively rainwater, greasy dirt or dust from getting in the electric machine casing; Guarantee the normal operation of motor reliably, prevent the damage of motor, prolong the useful life of motor.This is simple, and is with low cost, and beneficial effect is remarkable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1, be the structural representation of the utility model, label is respectively among the figure: afterbody end cap 1, electric machine casing 2, shaft extension end enclosing cover 3, electric machine main shaft 4 and block plate 5.The vertical machine hermetically-sealed construction of the utility model; Be to stretch out electric machine casing 2 and install a block plate 5 near the position of shaft extension end enclosing cover 3 at electric machine main shaft 4, this block plate 5 is with electric machine main shaft 4 rotations, can act on through its centrifugal force and will drop on top rainwater, greasy dirt or dust and get rid of to the space beyond the electric machine casing 2; Thereby prevent that effectively rainwater, greasy dirt or dust from getting in the electric machine casing 2; Guarantee the normal operation of motor reliably, prevent the damage of motor, prolong the useful life of motor.Said block plate 5 is connected with electric machine main shaft 4 close-fittings, can avoid dirt to fall into electric machine casing 2 along electric machine main shaft 4 seepages like this, and is easy for removal and installation again.Said block plate 5 is a disk structure, and its diameter is equal to or greater than the diameter of shaft extension end enclosing cover 3, can the connecting bolt on the shaft extension end enclosing cover 3 all be covered, and prevents that dirt from being got in the electric machine casing 2 by the connecting bolt hole.Said electric machine main shaft 4 stretches out electric machine casing 2 and also is coated with sealing ring 6 near the position of housing 2, and sealing ring 6 can further prevent like this that with electric machine main shaft 4 rotations dust is by in the entering housing 2 between said block plate 5 and the housing 2.
