Description

Carbon brush group (1)

This creation is related to carbon brushes; in particular, a carbon brush set.

Referring to FIG. 1, an exemplary embodiment of a conventional carbon brush set 100 for use in an electromechanical device having a rotating member (such as a motor or the like, not shown) is disposed on the rotating member. There is a collector ring 9, and the slip ring 9 rotates as the rotating member operates. The carbon brush set 100 is used in conjunction with the slip ring 9 and mainly includes a casing 1, a fixing rod 2 and a plurality of carbon brush holders 3, wherein the fixing rod 2 is fixed on the casing 1 and is electrically connected to the casing. The rings 9 are parallel, and the carbon brush holders 3 are disposed in parallel on the fixing rod 2. Each of the carbon brush holders 3 has a constant hole 3a, two arms 3b and a two-carbon brush 3c, wherein the through hole 3a is passed through the fixing rod 2, and the two carbon brushes 3c are respectively disposed on the arm 3b. Up and in contact with the slip ring 9. By maintaining the contact relationship between the carbon brushes 3c and the slip ring 9, it is ensured that the slip ring 9 (and the rotating member) can continuously transmit current or signal even under high-speed rotation. .

However, the conventional carbon brush set 100 has several major disadvantages as shown in FIG. 1. First, the carbon brush holders 3 fixed on the fixing rod 2 need to be adjusted one by one to obtain the respective carbon brush holders 3. The two-carbon brush 3c can be properly contacted with the collector ring 9, so the installation step is complicated; secondly, even after the carbon brush holders 3 are installed, if the fixing rod 2 is externally forced relative to the casing 1 The rotation also causes the carbon brush holders 3 to be all offset together, so that the two carbon brushes 3c of the carbon brush holders 3 cannot maintain good contact with the collector rings 9. In addition, since the cross-sectional shape of the through hole 3a and the fixing rod 2 of each of the carbon brush holders 3 are generally circular, the current collecting ring 9 is rotated at a high speed during operation of the electromechanical device. Each of the carbon brush holders 3 is easily deflected accordingly (as is apparent in FIG. 1 , the angles of the carbon brush holders 3 are mutually skewed), which is particularly disadvantageous for ensuring the two carbon brushes 3c of the carbon brush holders 3 and Stable contact between the slip rings 9.

In view of this, the purpose of this creation is to provide a carbon brush set without deliberately adjusting the applicable angle of the carbon brush holder and avoiding the angle shift.

In order to achieve the above object, the carbon brush set provided by the present invention comprises a frame body, a support member and a carbon brush holder; wherein the support member comprises a sleeve and a mandrel, wherein the sleeve is a hollow insulating tube. The mandrel is an elongated rod disposed inside the sleeve, the two ends of the sleeve are respectively coupled to the frame body, and the sleeve is not rotatable relative to the frame body; the carbon brush holder is disposed on the body On the support member, the carbon brush holder has a through hole having a hole shape which is not circular, and the sleeve is passed through, and the outer shape of the outer wall of the sleeve is matched with the through hole of the carbon brush holder.

Since the through hole is not circular, the carbon brush holder can be free from the step of adjusting the angle when disposed on the support member, and the angle of the carbon brush holder is fixed after the setting is completed, and no offset occurs.
