Abstract
The present utility model provides a lubricating oil injection device of a three-phase asynchronous motor, and the device belongs to the motor technical field. The device is provided to solve problems that the prior motor is not convenient for filling lubricating oil. The lubricating oil injection device of the three-phase asynchronous motor comprises a bearing cover sleeved on a motor rotating shaft, the bearing cap is fixedly connected with a motor body, and the bearing cover is provided with an oil injection hole communicated with a motor bearing. In the lubricating oil injection device of the three-phase asynchronous motor, oil can be filled without stopping the motor during the running process of the motor, lubrication state of the high-speed running bearing can be maintained for a long time, and service life can be greatly prolonged.
Description
Technical field
The utility model belongs to the motor technology field, relates to a kind of injection device of lubricating oil of threephase asynchronous machine.
Background technology
Existing threephase asynchronous machine is packed bearing behind the bearing pedestal into when assembling, and a certain amount of lubricating oil of annotating seals bearing then.Yet the sealing to bearing neither seal fully, and when motor rotation, bearing temperature raises, and lubricating oil Yin Wendu raises and degree of being stained with diminishes, and lubricating oil can send the slit to run off, and causes bearing to damage because of lubricating oil is not enough.Because motor speed is generally higher, user's lubricating oil of can't annotating in the use, existing solution is normally taken motor apart at motor rotation and is added lubricating oil after a period of time, very inconvenient.
And in existing national sector standard, 160 and the threephase asynchronous of following seat No. even also do not have the design of bearing cap, the dismounting trouble more of getting up.
Summary of the invention
The purpose of the utility model is to the existing in use the problems referred to above of existing threephase asynchronous machine, and has proposed a kind of device that can in motor operation course, can inject lubricating oil.
The purpose of the utility model can realize through following technical proposal: a kind of injection device of lubricating oil of threephase asynchronous machine; It is characterized in that; It comprises that socket is arranged on the bearing cap on the machine shaft; Bearing cap is fixedly connected with the motor body, offers the oil filler point that is connected with motor bearings on the described bearing cap.
Therefore bearing cap can together not rotate with rotating shaft owing to be connected with the motor body, when needs carry out oiling, the utensil aligning oil filler point that lubricating oil is housed is carried out oiling get final product.Whole oiling process can be under the operating condition at motor carries out.
In the injection device of lubricating oil of above-mentioned threephase asynchronous machine, the port of described oil filler point is provided with oil nozzle.Convenient through the oil nozzle oiling.
Compared with prior art, this threephase asynchronous machine injection device of lubricating oil can not shut down oiling in motor operation course, makes the bearing that runs up keep lubricating status for a long time, has prolonged useful life greatly.
Description of drawings
Fig. 1 is the structural scheme of mechanism that the utility model provides.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Among the figure, 1, rotating shaft; 2, bearing cap; 3, body; 4, oil filler point; 5, bearing; 6, oil nozzle.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As depicted in figs. 1 and 2; This threephase asynchronous machine injection device of lubricating oil comprises that socket is arranged on the bearing cap 2 on the machine shaft 1; Bearing cap 2 is fixedly connected with motor body 3, offers the oil filler point 4 that is connected with motor bearings 5 on the bearing cap 2, and oil filler point 4 places are provided with oil nozzle 6.
Bearing cap 2 is owing to be connected with motor body 3; Therefore can together not rotate, when needs carry out oiling, the utensil aligning oil nozzle 6 that lubricating oil is housed carried out oiling get final product with rotating shaft 1; Whole oiling process can be under the operating condition at motor carries out, and that has realized motor does not shut down oiling.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Claims (2)
