Technical background
It is to guarantee a gauged distance by outside end face and rotating shaft non-transmision end end face with outer bearing cover that existing motor is installed the tachometer structure, and on outer bearing cover, adopt standard seam and installing hole size, make when tachometer is installed, all be installed on the outer bearing cover by this standard size, thereby reach when no matter any tachometer is installed, all only need to change a tachometer and partly get final product, and need not to change the purpose of rotating shaft and outer bearing cover, thereby reduce many workloads, help standardized management.And for installing under the situation of grounding brush at the non-transmission side of motor, because grounding brush is to realize installing by the supporting bracket that is installed on the outer bearing cover, thereby tachometer can't be installed on the outer bearing cover again, the tachometer mounting structure of above-mentioned that cover standard just can't be realized.Though the method that grounding brush is installed in transmission side is arranged at present, but will have to like this rotating shaft shaft extension partly lengthened and be used to install grounding brush, this will have influence on the size of motor shaft extension and support footing, and this is of a size of the user installation size, if change this size, then will influence the versatility and the interchangeability of motor, and therefore must consider grounding brush is installed in non-transmission side.
See also Fig. 1; for the structural representation of grounding brush is installed in the prior art; comprise outer bearing cover 1 ', grounding brush 21 ', supporting bracket 22 ', rotating shaft 3 ' and protective cover 4 '; adopt protective cover 4 ' protective earthing brush 21 ', but the installation of protective cover 4 ' makes the structure of tachometer part have no way of installing.
See also Fig. 2, structural representation for the motor band tachometer of prior art, comprise outer bearing cover 1 ", rotating shaft 2 " and tachometer 3 "; in rotating shaft 2 " with outer bearing cover 1 " locate to leave standard tachometer mounting interface; but because rotating shaft 2 " diameter is greater than bearing cap 1 " seam; bearing cap 1 " with rotating shaft 2 " part blocks, thereby grounding brush can't be installed again.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and mounting structure that non-transmission side grounding brush of a kind of motor and tachometer are provided, it can be implemented in the non-transmission side of motor grounding brush and tachometer are installed simultaneously, both can play protective action, also realize installing the standard interface of tachometer simultaneously grounding brush.
The technical scheme that realizes above-mentioned purpose is: the mounting structure of non-transmission side grounding brush of a kind of motor and tachometer, comprise rotating shaft, outer bearing cover, supporting bracket, it is used at the non-transmission side of motor grounding brush and tachometer being installed, wherein, comprise that also one is bent into 90 ° and the carriage that is connected with the outer bearing cover rear end, one end of described carriage is provided with one first seam, the other end is provided with the first set installing hole in one second seam and this second seam, described supporting bracket is installed on the outer bearing cover of motor, the outer bearing cover of described motor is provided with one the 3rd seam, and the 3rd seam cooperates with first seam of carriage and is connected with spring washer by bolt.
The mounting structure of non-transmission side grounding brush of above-mentioned a kind of motor and tachometer, wherein, an end of described supporting bracket is fixed on the inside and outside bearing cap of the carriage rear surface by bolt and spring washer, other end fixed installation grounding brush.
The mounting structure of non-transmission side grounding brush of above-mentioned a kind of motor and tachometer, wherein, described tachometer has corresponding to the 4th seam of carriage second seam and first installing hole and second installing hole, to fixedly connected with carriage.
The mounting structure of non-transmission side grounding brush of above-mentioned a kind of motor and tachometer, wherein, the relative distance of described grounding brush and carriage inwall should remain on 10mm～15mm.
The mounting structure of non-transmission side grounding brush of above-mentioned a kind of motor and tachometer, wherein, the length of the rotating shaft of described motor extends to can install grounding brush.
The beneficial effects of the utility model are: the mounting structure of non-transmission side grounding brush of a kind of motor of the present utility model and tachometer, by adopting a carriage, solution can't will be installed tachometer and realize standard interface effectively with the problem of tachometer when non-transmission side is installed grounding brush.
Description of drawings
Fig. 1 is the structural representation of brush of the installation ground connection of prior art;
Fig. 2 is the structural representation of the motor band tachometer of prior art;
Fig. 3 is the structural representation of the mounting structure of non-transmission side grounding brush of a kind of motor of the present utility model and tachometer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 3, there is shown the mounting structure of non-transmission side grounding brush of a kind of motor of the present utility model and tachometer, be used for grounding brush 21 and tachometer 5 being installed at the non-transmission side of motor, comprise that rotating shaft 4, outer bearing cover 1, supporting bracket 22, are bent into 90 ° and the carriage 3 that is connected with outer bearing cover 1 rear end, wherein:
One end of carriage 3 is provided with one first seam 31, the other end is provided with the first set installing hole 33 in one second seam 32 and this second seam 32, adopt standard seam and installing hole size to realize the mounting interface of standard tachometer in the present embodiment, thereby reach standardization, the length of carriage 3 is decided according to the size of grounding brush 21, adopt foundry goods, for weight reduction be convenient to the maintenance of grounding brush 21, adopt four faggings two end faces to be connected the equal hollow out of remainder for carriage 3 present embodiments;
