Example (b):

referring to fig. 1, the present embodiment provides a scrap iron adsorption apparatus 100, which can be used on a speed reducer to reduce scrap iron in lubricating oil in a speed reducer case. The iron scrap adsorption device 100 comprises an outer cylinder 110, an inner cylinder 120 and an adsorption component 130, wherein the outer cylinder 110 is used for being connected with a mounting hole on a speed reducer box body; inner tube 120 and adsorption component 130 all set up in urceolus 110, and wherein, adsorption component 130 can adsorb the iron fillings among the lubricating oil, and inner tube 120 can carry out the shutoff with urceolus 110, prevents that adsorption component 130 from being dismantled the back lubricating oil and revealing.

Specifically, the outer cylinder 110 includes an outer cylinder body 112 and an end cap 113, the outer cylinder body 112 is cylindrical, the end cap 113 is disposed at one end of the outer cylinder body 112, and both are integrally formed. The end cover 113 is provided at a middle portion thereof with a fitting hole 1132 for fitting with the inner cylinder 120. The outer cylinder body 112 is provided with external threads at a portion thereof adjacent to the end cap 113, which are adapted to be fitted into a mounting hole formed in the bottom of the reduction gear case. In order to facilitate assembly and disassembly, a nut is further sleeved on the outer cylinder body 112. The nut is fixedly connected with the outer cylinder body 112, and the outer cylinder body 112 can be detached from the speed reducer or assembled with the speed reducer by rotating the nut. The outer circumferential surface of the outer cylinder body 112 is provided with a sealing ring, and the sealing ring is used for matching with a mounting hole of the reducer case.

The inner barrel 120 includes an inner barrel body 122 and a sealing head 124; the inner cylinder body 122 is a circular cylinder, and the sealing head 124 and the positioning ring 126 are respectively connected to two ends of the inner cylinder body 122. After the inner cylinder 120 and the outer cylinder 110 are assembled, the outer circumferential surface of the inner cylinder body 122 is matched with the matching hole 1132 of the outer cylinder 110; the seal head 124 is provided outside the outer cylinder 110, and is configured to seal the fitting hole 1132, and prevent leakage of the lubricant through a gap between the fitting hole 1132 and the inner cylinder body 122.

In order to improve the sealing effect, the sealing head 124 adopts a frustum-shaped structure; correspondingly, the outer end of the mating hole 1132 is provided with a chamfer. When the sealing head 124 abuts the end cap 113, the tapered surface of the sealing head 124 mates with the chamfered surface of the mating bore 1132. In addition, a sealing ring may be provided on an inner surface of the fitting hole 1132, thereby further improving a sealing effect.

The inner cylinder body 122 is provided with three oil passing holes 1222 on the wall near one end of the sealing head 124, and the three oil passing holes 1222 are respectively arranged along the outer circumferential surface of the inner cylinder body 122 and respectively extend along the axial direction of the inner cylinder body 122 to form strip-shaped holes. When the inner cylinder body 122 moves toward the inside of the reduction gear case, the oil passing hole 1222 moves into the case inside the outer cylinder 110 along with the inner cylinder body 122, so that the lubricating oil in the case can enter the inner cylinder body 122 through the oil passing hole 1222.

The adsorption component 130 is used for adsorbing iron filings in the lubricating oil in the inner cylinder body 122, and comprises a push rod 132 and an adsorption rod 134, wherein the push rod 132 and the adsorption rod 134 are cylindrical rods coaxially arranged. Also, the diameter of the push rod 132 is larger than that of the adsorption rod 134 so that both are formed in a stepped shaft shape. At this time, a stopper on the adsorption lever 134 is served by one end of the push lever 132. In other embodiments, an annular stop may be provided on the adsorption rod 134.

The adsorption rod 134 is inserted into the inner cylinder body 122 so that the end of the inner cylinder body 122 abuts against the stepped surface of the push rod 132. One end of the adsorption rod 134 near the oil passing hole 1222 is provided with a permanent magnet, so that iron chips in the lubricating oil in the inner cylinder body 122 can be adsorbed. The push rod 132 is slidably fitted into the inner hole of the outer cylinder body 112, and its end is exposed out of the outer cylinder body 112. In order to prevent the leakage of the lubricating oil in the inner cylinder body 122, a seal ring is provided between the push rod 132 and the outer cylinder body 112.

When the push rod 132 is pushed to move towards the direction close to the end cover 113, the push rod 132 can push the inner cylinder body 122 abutted against the push rod to move, so that the sealing head 124 moves towards the direction far away from the end cover 113, and the oil passing hole 1222 is pushed to the tail part of the end cover 113 and is communicated with the box body of the speed reducer. At this time, the position of the push rod 132 is fixed, that is, the oil passing hole 1222 is maintained to communicate with the case.

In order to fix the push rod 132 at the above position, the push rod 132 is provided with a snap-fit portion 136, and the outer cylinder body 112 is provided with a snap-fit portion 114. When the engaging portion 136 engages with the engaging portion 114, the position of the push rod 132 relative to the outer cylinder body 112 is fixed. Specifically, the push rod 132 is uniformly provided with three blind holes along the circumference thereof, and the clamping portion 136 is cylindrical and is inserted into the blind holes. The engaging portion 114 is disposed at an end of the outer cylinder body 112 away from the end cap 113, in this embodiment, the engaging portion 114 is a retaining ring; the baffle ring is fixedly connected with the end part of the outer cylinder body 112. The middle part of the baffle ring is provided with a through hole, three U-shaped clamping grooves are evenly arranged on the baffle ring, and the clamping grooves are communicated with the through hole. The push rod 132 penetrates through the through hole in the middle of the baffle ring, and when the push rod 132 is pushed, the clamping portion 136 can pass through the clamping groove; at this time, the push rod 132 is rotated around the axis of the push rod 132, and the engaging portion 136 can be rotated to the inner side of the stopper ring, thereby engaging the engaging portion 136 with the engaging portion 114. In other embodiments, the connection between the push rod 132 and the outer cylinder body 112 may be other detachable connection manners, for example, flanges are respectively disposed at the end of the push rod 132 and the end of the outer cylinder body 112, and the push rod 132 and the outer cylinder body 112 are connected by the flanges and bolts.

When the absorption assembly 130 is detached, in order to automatically seal the fitting hole 1132 of the end cover 113 of the outer cylinder 110 by the inner cylinder 120, the elastic member 140 is further sleeved on the inner cylinder body 122, and the positioning ring 126 is further connected to the end portion of the inner cylinder body 122. One end of the elastic member 140 abuts against the inner surface of the end cap 113, and the other end abuts against the positioning ring 126 at the end of the cylindrical body of the inner cylinder 120. In this embodiment, the elastic member 140 is a compression spring; the retaining ring 126 is threadably connected to the inner barrel body 122. When the adsorption component 130 is detached, the resisting force of the adsorption component to the inner cylinder body 122 disappears, and the elastic force of the elastic component 140 enables the inner cylinder 120 to move integrally in the direction away from the reducer case; so that the oil passing hole 1222 is moved to the inside of the outer cylinder 110 and the sealing head 124 seals the fitting hole 1132 on the end cover 113, thereby preventing the leakage of the lubricating oil.

In order to prevent the clamping portion 136 from falling off from the clamping groove of the baffle ring under the action of vibration, a groove is further formed in the inner surface of the baffle ring, and the clamping portion 136 is clamped in the groove. The inner cylinder 120 has a tendency to move toward the outside of the case under the elastic force of the elastic member 140; since the inner cylinder 120 abuts against the push rod 132, the inner cylinder 120 applies a certain abutting force to the push rod 132, and the abutting force causes the clamping portion 136 to be reliably clamped in the groove. When the adsorption component 130 needs to be detached, the push rod 132 is pushed towards the inner side of the box body first, so that the clamping portion 136 is separated from the groove, then the push rod 132 is rotated to enable the clamping portion 136 to correspond to the groove in the baffle ring, and then the push rod 132 is pulled out.

The theory of operation and the beneficial effect of iron fillings adsorber that this embodiment provided are as follows: when the iron chip absorber is used, the iron chip absorber is installed and fixed in the installation hole at the lower part of the reducer box body, and the oil passing hole 1222 on the inner cylinder 120 communicates the inner cavity of the inner cylinder body 122 with the inner cavity of the reducer box body under the abutting action of the push rod 132. The magnet on the adsorption rod 134 can adsorb iron pieces in the lubricating oil. When the iron filings on the adsorption rod 134 are more, the adsorption component 130 is detached, and the adsorption component 130 is reassembled after the iron filings on the adsorption rod 134 are removed. After the suction assembly 130 is detached, the inner cylinder 120 moves toward the outside of the casing by the elastic force of the elastic member 140, so that the oil passing hole 1222 is moved into the inner cavity of the outer cylinder 110, and the sealing head 124 seals the fitting hole 1132 of the end cover 113. Since the sealing head 124 has a solid structure, it can prevent leakage of the lubricant in the case.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
