As shown in fig. 1-2, the structure for collecting iron scraps in lubricating oil in the interior of a speed reducer comprises a speed reducer box body 1 and a plurality of iron scrap collecting units 2, wherein a plurality of mounting holes 11 matched with the iron scrap collecting units 2 are formed in the side walls of two ends of the speed reducer box body 1, one end of each iron scrap collecting unit 2 is fixed on the outer wall of the speed reducer box body 1, and the other end of each iron scrap collecting unit 2 penetrates through the corresponding mounting hole 11 and then is located in the speed reducer box body 1;

iron fillings collection unit 2 include mounting flange 21, lath 22 and a plurality of magnetic sheet 23, mounting flange 21 fix on the outer wall of speed reducer box 1, lath 22 pass 11 back be located speed reducer box 1 in, lath 22's one end and mounting flange 21 articulated, and lath 22's the other end installs the pulley 24 that drives its removal, pulley 24 and lath 22 rotate and be connected, the even both sides of fixing at lath 22 of magnetic sheet 23. The dispersed magnetic sheets 23 are used for replacing a concentrated magnetic core, so that the absorption capacity is stronger, the lubricating oil is contacted in a large area, and the iron scrap adsorption is more sufficient.

The mounting flange 21, one side install the adapter, the adapter on seted up first connecting hole, the one end of lath 22 seted up the second connecting hole, first connecting hole and second connecting hole between link to each other through the round pin axle. The lath 22 and the mounting flange 21 are connected in a hinged mode, so that the lath 22 can swing around a pin shaft, and even if machining errors exist in the mounting hole 11, the connecting part of the lath 22 and the mounting flange 21 cannot be broken.

The bottom in the speed reducer box 1 is provided with a plurality of slideways 12, and the pulleys 24 are respectively positioned in the slideways 12 corresponding to the pulleys. The pulleys 24 roll in the slide ways 12, so that the laths 22 can move smoothly when being assembled, and the phenomenon that the magnetic force generated by the magnetic sheets 23 causes difficulty in installation is avoided.

The bottom in the speed reducer box body 1 is provided with a plurality of shielding rib plates 13, and the laths 22 are all positioned below the shielding rib plates 13.

The shielding rib plates 13 are all provided with grooves 131, and the battens 22 are all positioned in the grooves 131. The shielding rib plate 13 plays a role in limiting the lath 22 and prevents the lath 22 from shaking along with lubricating oil.
