Abstract
The invention belongs to the technical field of manufacturing of motors. Specific to the technical problem that condensed water enters a motor in the using process of the conventional motor for a cooling tower. The invention provides a motor protection device for a cooling tower. The motor protection device comprises a bearing outer cover, wherein a framework sealing ring is arranged at the joint of the bearing outer cover and a motor rotating shaft. The motor protection device is characterized in that a seam allowance is formed in the joint of the bearing outer cover and a bearing inner cover; a first O-shaped sealing ring is formed in the seam allowance; the protection device further comprises a water throwing disk which is arranged on the outer side of the bearing outer cover; the water throwing disk is in interference fit with the motor rotating shaft; and a second O-shaped sealing ring is arranged at the joint of the water throwing disk and the motor rotating shaft. The protection device is reasonable in structure, is assembled compactly, and can be widely applied to motors used in various cooling environments.
Description
Technical field
The invention belongs to the motor manufacturing technology field, be specifically related to a kind of used for cooling tower motor protection device.
Background technology
Used for cooling tower motor degree of protection is IP55, and with the skeleton ring sealing, skeleton ring is installed on the bearing end cover, adopts the V6 mounting means in cooling tower, and namely motor-shaft extending upwards uses.Because the motor long time running easily makes skeleton ring that some wearing and tearing are arranged, add and very easily form condensed water in the cooling tower, condensed water can enter motor internal along shaft extension, although with weeper, the user is still reflected has water to enter on end cap and terminal box, affect the normal operation of motor.
Summary of the invention
For solving the in use condensed water technical problem that enters motor internal of present used for cooling tower motor, the invention provides a kind of used for cooling tower motor protection device.
The technical solution used in the present invention is: the used for cooling tower motor protection device, comprise bearing end cover, bearing end cover and machine shaft junction are provided with backbone sealing ring, it is characterized in that: described bearing end cover and internal bearing cover junction are provided with seam, and stop portion is provided with an O RunddichtringO; Described protector also comprises the water-throwing disk that is arranged on the bearing end cover outside, water-throwing disk and machine shaft interference fit, and water-throwing disk and machine shaft junction are provided with the 2nd O RunddichtringO.
The used for cooling tower motor does not find that through using condensed water enters into motor internal after adopting this protector, and motor even running time and life-span are significantly improved, and the user is reflected well.This protective device structure is reasonable, and assembling is compact, among the motor that can be widely used in using in the various cooler environments.
Description of drawings
Accompanying drawing is structure cutaway view of the present invention.
Among the figure, 1, bearing end cover, 2, internal bearing cover, 3, backbone sealing ring, the 4, the one O RunddichtringO, 5, water-throwing disk, the 6, the 2nd O RunddichtringO, 7, machine shaft.
Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
As shown in drawings, the used for cooling tower motor protection device comprises bearing end cover 1, and bearing end cover 1 is provided with backbone sealing ring 3 with machine shaft 7 junctions.
As shown in drawings, bearing end cover 1 is provided with seam with internal bearing cover 2 junctions, and stop portion is provided with an O RunddichtringO 4.
As shown in drawings, this protector also comprises the water-throwing disk 5 that is arranged on bearing end cover 1 outside, water-throwing disk 5 and machine shaft 7 interference fit, and water-throwing disk 5 is provided with the 2nd O RunddichtringO 6 with machine shaft 7 junctions.
After adopting above-mentioned protector, motor in the running water-throwing disk rotates with machine shaft, condensed water is got rid of away by water-throwing disk, because between water-throwing disk and the machine shaft, be respectively equipped with sealing ring between bearing end cover and machine shaft, the internal bearing cover, namely be that a small amount of condensed water attaches and can prevent effectively also that on bearing end cover it from entering motor internal, thereby guaranteed the even running of motor.
