Abstract
The utility model relates to an oil-leakage preventing device for an end cover type sliding bearing motor, which comprises annular wind deflectors on the inner sides of end over type sliding bearings at two ends of a motor rotating shaft and are arranged on the motor rotating shaft in a heat sleeve manner. For eliminating the negative pressure generated by ventilation, a baffle is additionally arranged on the inner side of the bearing and a wind path is divided into two parts, wherein one part blows towards inner oil covers of the bearings to greatly reduce the negative pressure, thereby overcoming the phenomenon that the motor leaks oil and improving the operation reliability of the motor. The improvement of the utility model has the advantages of low cost and the like, is easy for operation and low in cost and can run reliably.
Description
Technical field
The utility model belongs to the motor device field, relates to a kind of anti-oil leakage device, especially a kind of anti-oil leakage device that is applicable to end cover type sliding bearing motor.
Background technology
In the prior art, big-and-middle-sized threephase asynchronous adopts the end cover type sliding bearing, there are certain clearance in motor shaft and internal bearing cover, because the influence that motor internal ventilates, produce negative pressure at the internal bearing cover place, thin oil in the bearing is drawn onto in the motor, destroy electrical machine insulation, contaminated environment and waste lubricating oil greatly causes unnecessary loss to the client.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of anti-oil leakage device that is used for end cover type sliding bearing motor is provided, and this device can effectively stop the interior thin oil of bearing to be inhaled in the motor, pollutes thereby reduce, and reduces loss.
The purpose of this utility model solves by the following technical programs:
This anti-oil leakage device that is used for end cover type sliding bearing motor comprises the annular deep bead that is arranged at end cover type sliding bearing inboard, machine shaft two ends respectively, and described annular deep bead adopts the form of hot jacket to be arranged on the machine shaft.
Above-mentioned annular deep bead is that set a distance is 20～30mm apart from the end cover type sliding bearing at machine shaft two ends.
Further, the external diameter of above-mentioned annular deep bead is greater than oil cap external diameter 15～25mm in the described end cover type sliding bearing.
The utility model because the negative pressure of ventilating and producing increases a baffle plate in the bearing inboard, is divided into two partly with wind path in order to eliminate, a part blows to oil cap in the bearing, cut down negative pressure widely, thereby solved the motor oil leakage phenomenon, improved running reliability of motor.That improvement of the present utility model has is easy to operate, cost is low, advantage such as reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1 is the end cover type sliding bearing; 2 is deep bead; 3 is machine shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, this kind is used for the anti-oil leakage device of end cover type sliding bearing motor, comprises the annular deep bead 2 that is arranged at end cover type sliding bearing 1 inboard, machine shaft 3 two ends respectively, and annular deep bead 2 adopts the form of hot jacket to be arranged on the machine shaft 3.Annular deep bead 2 is set a distance L apart from the end cover type sliding bearing 1 at machine shaft 3 two ends.It is suitable that this deep bead 2 and end cover type sliding bearing 1 interior oil cap distance and deep bead 2 external diameters will be obtained, otherwise do not have the leakage of oil problem that solves, general set a distance L is 20～30mm, and the external diameter of deep bead 2 is greater than oil cap external diameter 15～25mm in the described end cover type sliding bearing.In the most preferred embodiment of the present utility model, the external diameter of deep bead 2 is greater than oil cap external diameter 20mm in the end cover type sliding bearing.
