Abstract
The utility model relates to a motor goes out axle waterproof construction belongs to motor technical field. The motor output shaft penetrates through the bearing and the hole of the lip-shaped sealing ring; two lip-shaped sealing rings are sequentially arranged in the hole for mounting the lip-shaped sealing ring. A sealing space is formed between the two sealing rings, and a lubricant is added into the sealing space of the lip-shaped sealing ring on the outer side. The utility model has the advantages that: lubricant is added into a sealing space between the lip-shaped sealing rings and is locked in the sealing space formed by the two lip-shaped sealing rings, so that the lubrication cannot be failed, and the protection grade of the motor is improved; the sealing and waterproof effects are obvious, the protection grade of the motor is obviously improved, and the service life of the motor is obviously prolonged.
Description
Technical Field
The utility model relates to a motor goes out axle waterproof construction belongs to motor technical field.
Background
The existing motor output shaft sealing or water proofing is mainly realized by a lip-shaped sealing ring for sealing or water proofing, lubricating oil or lubricating grease is mainly smeared on the lip-shaped sealing ring under the condition of no circulating lubrication to realize the lubricating effect between the motor output shaft and the lip-shaped sealing ring, and when the motor works, the motor output shaft and the lip-shaped sealing ring are in dynamic friction action, so that heat can be generated, and the lubrication can be evaporated, lost, reduced and failed after the motor output shaft runs for a period of time. So that the protection level of the motor is reduced, the motor can not meet the sealing requirement, the motor is not watered, and the like.
Disclosure of Invention
In order to overcome above-mentioned prior art's weak point, the utility model provides a motor goes out axle waterproof construction adds emollient in the seal space between the lip sealing washer, and emollient is locked in the seal space that two lip sealing washers formed, and the lubrication can not become invalid, and motor protection level obtains improving.
The utility model discloses a realize through following technical scheme: the utility model provides a motor goes out axle waterproof construction which characterized in that: the motor output shaft penetrates through the bearing and the hole of the lip-shaped sealing ring; two lip-shaped sealing rings are sequentially arranged in the hole for mounting the lip-shaped sealing ring.
A sealing space is formed between the two sealing rings, and a lubricant is added into the sealing space of the lip-shaped sealing ring on the outer side.
The utility model has the advantages that: lubricant is added into a sealing space between the lip-shaped sealing rings and is locked in the sealing space formed by the two lip-shaped sealing rings, so that the lubrication cannot be failed, and the protection grade of the motor is improved; the sealing and waterproof effects are obvious, the protection grade of the motor is obviously improved, and the service life of the motor is obviously prolonged.
Drawings
The invention will be further explained below with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. motor output shaft 2, motor end cover 3, lip type sealing washer 4, bearing.
Detailed Description
A motor goes out axle waterproof construction as shown in figure 1, its characterized in that: the motor output shaft structure comprises a motor output shaft 1, a motor end cover 2 and a lip-shaped sealing ring 3, wherein a bearing 4 and a hole for mounting the lip-shaped sealing ring 3 are arranged in the motor end cover 2, the lip-shaped sealing ring 3 is placed in the hole, and the motor output shaft 1 penetrates through the bearing 4 and the hole for mounting the lip-shaped sealing ring 3; two lip-shaped sealing rings 3 are sequentially arranged in the hole for installing the lip-shaped sealing ring 3.
A sealing space is formed between the two sealing rings 3, and a lubricant is added into the sealing space of the lip-shaped sealing ring 3 at the outer side.
Lubricant is added into the sealed space between the lip-shaped sealing rings, the lubricant is locked in the sealed space formed by the two lip-shaped sealing rings, evaporation, loss and reduction cannot be generated, the lubrication cannot be failed, and the protection grade of the motor is improved; the sealing and waterproof effects are obvious, the protection grade of the motor is obviously improved, and the service life of the motor is obviously prolonged.
The utility model discloses increase the motor protection, improve the motor life-span, be applicable to various motors.
