Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 2, an electric brush carbon powder collecting structure for a vertical bearing comprises a base body, wherein a collecting ring 1 for collecting carbon powder is arranged on the base body, a thrust head 2 is arranged in the base body, a guide piece 3 for guiding carbon powder is arranged on the thrust head 2, a rotor 8 is arranged at the center of the thrust head 2, a collecting ring 9 is arranged on the rotor 8, a carbon brush 91 is arranged on the inner side of the collecting ring 9, and the inner side of the carbon brush 91 is abutted against the outer side face of the rotor 8; the carbon brush 91 rubs with the rotor 8 to generate fine carbon powder, the guide piece 3 guides the carbon powder into the collecting ring 1, and the collecting ring 1 prevents the carbon powder from entering the inside of the frame 4 to pollute lubricating oil and damage the vertical bearing.

The pedestal includes frame 4, is equipped with end cover 5 in the

frame

4, and 5 below of end cover are equipped with solid fixed ring 6, and end cover 5 passes through bolt detachably with solid fixed ring 6 to be connected, gu fixed 6 bottom surfaces and 4 top surface butts of frame, gu fixed 6 external diameter is greater than the external diameter of frame 4 for end cover 5 places in frame 4 on the joint can, simple structure, it is convenient to use and maintain.

Collecting ring 1 is located end cover 5 top, and collecting ring 1 is connected with end cover 5 detachably through the bolt, and collecting ring 1 top is equipped with two annular risers 11, and the recess in the middle of two risers 11 is collecting vat 12, and collecting vat 12's degree of depth accessible is changed collecting ring 1 and is adjusted, can collect a large amount of carbon dust, prevents effectively that the carbon dust from getting into frame 4.

Guide 3 includes retaining ring 31 and guide ring 32, retaining ring 31 locates the top of thrust collar 2, be connected with thrust collar 2 through the bolt, the internal diameter of retaining ring 31 is less than the internal diameter of carbon brush 91, make carbon brush 91 and rotor 8 friction, produce the carbon powder of tiny granule, drop on retaining ring 31, and can not get into frame 4, the top surface outside of thrust collar 2 is equipped with the screens groove, guide ring 32 passes through the bolt fastening in the screens groove, the top surface outer fringe of guide ring 32 is equipped with the direction slope 321 of downward sloping, look down from looking down, the vertical projection of direction slope 321 outer fringe is in collecting vat 12.

When the vertical bearing operates, the carbon brush 91 in the collecting ring 9 rubs with the rotor 8 to generate fine carbon powder, and the fine carbon powder falls down on the retainer ring 31 and falls into the collecting tank 12 from the guide slope 321 on the outer side after being accumulated to a certain degree.

The center of end cover 5 is equipped with logical groove, and thrust collar 2 is located logical inslot, and the top of logical groove is equipped with the ring channel, is equipped with sealing washer 7 in the ring channel, and the upper and lower both sides of sealing washer 7 respectively with the bottom surface of collecting ring 1 and the ring channel bottom surface butt of end cover 5, the medial surface of sealing washer 7 and the lateral surface butt of thrust collar 2.
