Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below with reference to Fig. 1 to Fig. 4 a kind of motor embodiment with rear-mounted terminal box of the utility model being done and describing clearly and completely further.Obviously, described embodiment is section Example of the present utility model, instead of whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of the utility model protection.
A kind of motor with rear-mounted terminal box, comprise motor housing 1, be positioned at the output shaft 2 of motor housing 1 one end, described motor housing 1 is provided with junction box assembly 3, described junction box assembly 3 comprises the junction box body 31 be connected with motor housing 1, connector cover 32, described junction box assembly 3 is positioned on motor housing 1 one end away from output shaft 2, described junction box body 31 is provided with the buckling hole 33 for fastening with connector cover 32, described buckling hole 33 is positioned on the sidewall of junction box body 31 away from motor housing 1, because installed surface is generally all horizontal, and after this motor installation be with installed surface in vertical state, namely whole motor output shaft 2 is in vertical laying state, junction box assembly 3 is arranged on motor housing 1 one end away from output shaft 2, namely junction box assembly 3 is positioned at the side of motor housing 1 away from ground, junction box body 31 is provided with the buckling hole 33 for fastening with connector cover 32, buckling hole 33 is positioned on the sidewall of junction box body 31 away from motor housing 1, now connector cover 32 can be positioned at junction box body 31 too away from the sidewall on ground, the motor of this kind of structure, first, junction box body 31 and output shaft 2 lay respectively on the relative end of two of junction box body 31, thus make the lateral wall adjacent with output shaft 2 of motor housing 1 leaves the holding space that major part can hold for installation personnel, now avoid whole junction box assembly 3 without the need to installation personnel to operate, very convenient during installation, secondly, in wiring process, because buckling hole 33 is positioned on the sidewall of junction box body 31 away from motor housing 1, maintenance personal health to carry out dismounting connector cover 32 without the need to side, only need health is straight and upright, then direct control, not only the physical demands of maintenance personal is reduced further, operating efficiency gets a promotion, and visibility during operation significantly promotes, and improves fail safe in installation process.
The lateral wall adjacent with buckling hole 33 of junction box body 31 is also provided with the through hole 4 for installing external cable line, installation personnel is when installing external cable, external cable is needed to carry out the fixing of external cable through through hole 4, consider actual installation situation, the position of the terminals connected with attaching plug of general external cable is usually located at lower than motor position, this through hole 4 is positioned on the lateral wall adjacent with buckling hole 33 of junction box body 31, external cable, through while through hole 4, plays the effect of fixing external cable on the one hand; On the other hand, also can play the effect of bending external cable, and make the external cable after bending can keep its flexibility the moment, stability maintenance is improved significantly.
The shape of motor housing 1 is cylindrical, the periphery wall of described motor housing 1 is provided with mounting bracket 5, described mounting bracket 5 is provided with installing hole 6, damping washer 7 is provided with in described installing hole 6, described damping washer 7 is provided with for the clamping part 8 with installing hole 6 clamping, through hole 9, the support set 10 for supporting fastening bolt is provided with in described through hole 9, the trepanning 11 run through for fastening bolt is provided with in described support set 10, clamping part 8 on damping washer 7 and installing hole 6 clamping mutually, and support set 10 is inserted in through hole 9, in the process that reality is fixing, fastening bolt is inserted in the trepanning 11 of support set 10, then this nuts can be conflicted with the end of support set 10, can conflict with installed surface in one end away from nuts of support set 10, when fastening bolt is tightened, support set 10 is directly fixed between installed surface and fastening bolt, reach the object of fixing fastening bolt, even if now fastening bolt is continued to tighten, also breaking of damping washer 7 can not be caused, owing to there is support set 10 between fastening bolt body and the hole wall of installing hole 6, even if service time is longer, fastening bolt body also there will not be the state of inclination, and fixing stability is higher.
Damping washer 7 comprises washer body 71, described clamping part 8 comprises and being positioned on washer body 71 lateral wall and the buckle annular groove 81 that can engage with installing hole 6 aperture, because the hole shape of installing hole 6 is generally circle, adopt the mode directly offering buckle annular groove 81 on washer body 71 lateral wall, first, the manufacture craft in early stage of whole damping washer 7 can be saved, save cost; Secondly, actual snap-fitting process is also more convenient, only washer body 71 need be squeezed in installing hole 6, until buckle annular groove 81 engages with installing hole 6 aperture, is simple and easy to dress.
Buckle annular groove 81 washer body 71 be separated into can be inconsistent with the nuts of fastening bolt upper gasket 12, lower gasket 13, in motor installation use procedure, motor body there will be vibrations, now upper gasket 12 and nuts are conflicted, play the effect of damping, lower gasket 13 directly can be conflicted with installed surface in addition, and play the effect of lower damping, dual shock absorption makes the damping effect of whole motor more outstanding.
The thickness size of upper gasket 12 is a, and the thickness size of lower gasket 13 is b, and wherein a equals b, and damping can be made to reach consistent with the effect of lower damping, avoids the inclined shake caused because of the difference of damping effect.
The above is only exemplary embodiment of the present utility model, but not for limiting protection range of the present utility model, protection range of the present utility model is determined by appended claim.
