Abstract
The utility model belongs to the electric motor manufacture field. For solving the serious technical problem of present motor axial compressor carbon brush wearing and tearing, the utility model provides an axle is with ground connection carbon brush device, including a cylindric brush holder, its characterized in that: the excircle of brush holder is equipped with two insulating washer that can freely remove on the surface, is equipped with the surface screw -thread fit of lock nut, lock nut and brush holder in two insulating washer's both sides, being equipped with carbon brush head and conducting block in the inside of brush holder, weaving the brush pigtail that forms through the copper line between carbon brush head and the conducting block and be connected, be equipped with the spring between carbon brush head and conducting block, the spring housing is on the brush pigtail, and the tip of brush holder is stretched out to the one end of carbon brush head, the internal surface of the brush holder other end is equipped with the internal thread, and a bolt gos deep into brush holder inside and offsets with the conducting block with interior screw -thread fit, is equipped with the earth connection on the bolt. This carbon brush mounted position approaches the rotation center of pivot for the linear velocity reduces, reduces the wearing and tearing of carbon brush, can effectively prolong the life -span of carbon brush.
Description
Technical field
The utility model belongs to field of motor manufacturing, relates to a kind of axle grounding carbon brush device.
Background technology
At present in frequency conversion, servomotor or heavy-duty motor, for eliminating the destruction of shaft current for bearing, grounding carbon brush can be loaded onto on the rotation profile of rotating shaft, the shaft current that motor produces is imported to the earth.Current carbon brush structure is more complicated, and carbon brush is arranged on the excircle configuration face of rotating shaft, and the linear velocity at contact-making surface place is high, and carbon brush abrasion is serious, and comparative lifetime is shorter.Accompanying drawing one is structure and the application thereof of current carbon brush.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of axle grounding carbon brush device, and this axle grounding carbon brush device is arranged on the shaft extension end face of motor, thus reaches the linear velocity reducing carbon brush and rotate, and extends the life-span of carbon brush.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: a kind of axle grounding carbon brush device, comprise a cylindric brush carrier, it is characterized in that: on the outer round surface of described brush carrier, be provided with two insulating washers that can move freely, be provided with locking nut in the both sides of two insulating washers, locking nut coordinates with the outer surface thread of brush carrier; Be provided with carbon brush head and conducting block in the inside of brush carrier, carbon brush head is connected with the brush pigtail by copper wire woven between conducting block, between carbon brush head and conducting block, be provided with spring, and spring housing is on brush pigtail, and the end of brush carrier is stretched out in one end of carbon brush head; The inner surface of the brush carrier other end is provided with internal thread, and a bolt and screw-internal thread fit are goed deep into brush carrier inside and offseted with conducting block, and bolt is provided with earth connection.
The beneficial effects of the utility model are: carbon brush installation site, close to the pivot of rotating shaft, makes linear velocity reduce low, reduces the wearing and tearing of carbon brush, effectively can extend the life-span of carbon brush.
