Embodiment Construction

[0009] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0010] Such as Figure 1 ~ Figure 2 As shown, it includes an oil deflecting ring body 1, on which the oil deflecting ring body 1 is provided with a central hole 2 of the oil deflecting ring, and a thread 3 is arranged in the central hole 2 of the oil deflecting ring, and on the said oil deflecting ring body 1 is equidistantly provided with small holes 4,

[0011] The present invention only needs to change the fit of the oil deflecting ring, from interference fit to thread fit; the corresponding part shaft is provided with thread. The M140X2 thread is a thread with a diameter of 140 and a pitch of 2.

[0012] The cooperation between the oil retaining ring body 1 and the shaft is replaced by threaded connection M140X2, and the rest remains unchanged. The threaded connection does not need to be heated, as long as it is tightened along the thread, no additional e...

Abstract

The invention relates to an oil retainer structure of a novel three-phase asynchronous motor, wherein the oil retainer structure of the novel three-phase asynchronous motor comprises an oil retainer body; small holes are arranged on the oil retainer body at equal intervals; and the center of the oil retainer body is provided with an oil retainer central hole which is internally provided with a thread. The oil retainer structure of the novel three-phase asynchronous motor provided by the invention is compact and reasonable in structure; the oil retainer structure is connected with a shaft and is not required to be heated; the oil retainer structure of the novel three-phase asynchronous motor is simple to process, convenient to operate, short in cycle, low in cost and high in operating efficiency, and does not change the original assembling method and using requirements of a motor.

Description

technical field [0001] The invention relates to an oil deflecting ring, in particular to a new type of oil deflecting ring structure for a three-phase asynchronous motor, which is used for the oil deflecting beside the front and rear bearings of the three-phase asynchronous motor. Background technique [0002] The oil deflector ring is a device used to retain oil in the motor bearing. The design and processing of the oil deflector ring is very important. Its cooperation with the shaft and the shape of the oil deflector ring play a key role in the oil retaining effect of the motor bearing. At present, the most used motor oil deflector ring on the market adopts an interference fit with the shaft. It needs to be heated to be installed on the shaft, and its assembly is difficult and time-consuming, which can no longer meet the existing production needs, and in the production process, the processing is difficult, the cycle is long, and the cost is high. Contents of the inventio...
