Abstract
The utility model discloses a novel ventilation structure with integrated balance ring and ventilation tube. The novel ventilation structure comprises a support (1) sheathed on a rotor shaft and a ventilation tube (2) arranged at the periphery of the support (1); the support is provided with the balance ring (3); and the balance ring (3) and the support (1) are integrated into a whole. As the support is provided with the balance ring which is integrated with the support, the novel ventilation structure adopting the structure carries out the secondary balance of the whole rotor, can improve the balance precision and does not affect the original balance condition of the internal fan, thus being capable of reducing the harmful vibration and noise generated by the motor.
Description
Technical field
The utility model relates to a kind of electric machine structure, and especially a kind of gimbal and ventilating duct are the novel ventilated structure of one.
Background technology
At present, the threephase asynchronous of selling on the market is in order to reach the purpose to the rotor cooling, between internal fan and rotor, the ventilating duct structure is installed usually, so that the air quantity that internal fan is discharged can arrive the rotor position as much as possible, the temperature of taking away the rotor position reaches the purpose of cooling.Also can there be the balance problem in rotor in operation process, because the imbalance of rotor is the major reason that motor produces nuisance vibration and noise.Existing ventilating duct structure be directly be enclosed within armature spindle on fastening connection of bearing, there is not balanced structure in the ventilating duct periphery, after rotor has been adorned internal fan, fan end can only be carried out secondary balancing again on internal fan, this has just destroyed independent equilibrium condition before the internal fan assembling, and balance quality also is restricted.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly can improve the gimbal of balance quality and the novel ventilated structure that ventilating duct is one.
Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises the ventilating duct that is enclosed within the bearing on the armature spindle and is installed in the bearing periphery, and described bearing is provided with gimbal, and gimbal and bearing are structure as a whole.
The said structure that the utility model adopts, owing on described bearing, be provided with gimbal with the bearing integrative-structure, on this, carry out the secondary balancing of whole rotor, can improve the precision of balance, can not influence the original equilibrium condition of internal fan yet, thereby can reduce nuisance vibration and noise that motor produces.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Figure 1 shows that structural representation of the present utility model
Figure 2 shows that the left view of Fig. 1
The specific embodiment
By accompanying drawing as can be known, the utility model comprises bearing 1 that is enclosed within on the armature spindle and the ventilating duct 2 that is installed in bearing 1 periphery, and described bearing is provided with gimbal 3, and gimbal 3 is structure as a whole with bearing 1.During installation, two sections bearings with the band gimbal welded together about ventilating duct was divided into, and integral assembling is on armature spindle again.Also can have the groove of ring-type on the gimbal.The scope that the utility model is described the soverlay technique scheme, and the various variations of claim scope, any modification or improvement that those skilled in the art that the utility model is done realize easily all belong to the utility model scope required for protection.
Claims (1)
1, a kind of gimbal and ventilating duct are the novel ventilated structure of one, comprise the ventilating duct that is enclosed within the bearing on the armature spindle and is installed in the bearing periphery, it is characterized in that described bearing is provided with gimbal, and gimbal and bearing are structure as a whole.
