Abstract

The utility model provides a device used for filling oil into a bearing, which is especially suitable for the oil filling of a rotary cup bearing on an airflow spin. The bearing oil filler comprises a hand holding frame, a rack, a detent, a spanner, a position limiting shaft and an injector; the spanner is connected on the hand holding frame by the a rotating shaft which is provided with a return spring; one end of the return spring leans on the spanner and the other end is pivotally connected with the hand holding frame, thus leading the spanner to be recovered at any moment. A detent shaft is connected with the end of the spanner; a reset sheet is fixedly connected with the end of the spanner and presses on the detent; the rack is arranged on the hand holding frame in a sliding way; a ratchet of the rack is connected with the detent; under the action of the recovery sheet, the detent always keeps being connected with the detent; the injector comprises an injection pipe, a pushing rod and an injection needle; the injection pipe is clamped on the hand holding frame; the pushing rod is connected with the end of the rack 2 by a retaining block. The bearing oil filler can realize that the oil is extruded beside a bearing raceway quantificationally, and does not scrape the bearing raceway and steel balls.

Description

The bearing oil filler

Technical field

The utility model is a kind of device that refuels in the bearing, and the rotor bearing that is specially adapted on the air spinning refuels.

Background technique

Bearing in use for some time, need regularly bearing to be refueled, the general oiling is to refuel with common syringe or grease gun, directly grease is injected from tank filler sleeve, the shortcoming of this oiling is: 1, can not quantitative refueling, particularly add too much, and making bearing produce the heat that running produces can not effectively distribute, grease causes bearing load to increase more, produces more heat; 2, can not be added to oil the raceway position of bearing, thereby make bearing can not get effective lubricating, cause bearing to damage in early days.

Summary of the invention

The purpose of this utility model is in order to overcome with ordinary syringe or grease gun oiling and to cause oiling can not quantitatively reach oiling shortcoming not in place, the fine bearing oil filler that also can carry out quantitative refueling near bearing race of a kind of entry needle energy of special invention.

The purpose of this utility model realizes as follows: described bearing oil filler comprises hand-held frame, sour jujube bar, ratchet, wrench, position-limited shaft and injector; Wrench is connected on the hand-held frame by rotating shaft, and rotating shaft is provided with return spring, and an end of return spring abuts against on the wrench, the other end is hinged on the hand-held frame, makes wrench return at any time, and pawl axis is connected on the end of wrench, reseting plate is fixed in the end of wrench, and reseting plate is pressed on the ratchet; The sour jujube bar is slidingly arranged on the hand-held frame, and ratchet and ratchet on the sour jujube bar join, and under the effect of reseting plate, ratchet remains the state that joins with ratchet; Injector comprises injection tube, push rod and entry needle, and injection tube is connected on the hand-held frame, and push rod is connected the end of sour jujube bar by block.

Be connected with driving lever on the described ratchet, driving lever is used to control the coupled condition of ratchet and ratchet, and driving lever is to pressing down, and ratchet lifts, and ratchet separates with ratchet; When unclamping driving lever, under the effect of reseting plate, ratchet and ratchet join.

Described entry needle is crooked; The needle point of described entry needle is blunt.

Good effect of the present utility model is as follows: the utility model is the displacement that drives the sour jujube bar of stirring that utilizes ratchet, the displacement of sour jujube bar drives the push rod of injector again, again the grease in the injection tube quantitative be extruded into bearing race next door, because being backup plate hand pulling again and again, the displacement of sour jujube bar finishes, spanner is placed restrictions on its amounts of rotation by position-limited shaft, so can accomplish quantitative displacement, guarantee the quantitative injection of grease; Because entry needle is crooked, so that entry needle can enter into the tank filler sleeve of bearing exactly, extend into the bearing race annex easily; Because the needle point of entry needle is blunt, institute is not so that entry needle can scratch bearing race and steel ball; Bearing can prolong the working life of bearing after carrying out regular quantitative refueling, can save grease, prevents to add the grease loss that oil causes.

Embodiment

As shown in Figure 1, described bearing oil filler comprises hand-held frame 1, sour jujube bar 2, ratchet 3, wrench 6 and injector 5; Wrench 6 is connected on the hand-held frame 1 by rotating shaft 15, and rotating shaft 15 is provided with return spring 4, and an end of return spring 4 abuts against on the wrench 6, and the other end is hinged on the hand-held frame 1, makes wrench 6 return at any time; Position-limited shaft 7 is installed in a special position on the hander.Ratchet 3 is coupling in the end of wrench 6, and reseting plate 8 is fixed in the end of wrench 6, and reseting plate 8 is pressed on the ratchet 3; Sour jujube bar 2 is slidingly arranged on the hand-held frame 1, and the ratchet 9 on the sour jujube bar 2 joins with ratchet 3, and under the effect of reseting plate 8, ratchet 3 remains the state that joins with ratchet 9; Injector 5 comprises injection tube 10, push rod 11 and entry needle 12, and injection tube 10 is connected on the hand-held frame 1, and push rod 11 is connected the end of sour jujube bar 2 by block 13.

Be connected with driving lever 14 on the described ratchet 3, driving lever 14 is used to control the coupled condition of ratchet 3 and ratchet 9, and driving lever 14 is to pressing down, and ratchet 3 lifts, and ratchet 3 separates with ratchet 9; When unclamping driving lever 14, under the effect of reseting plate 8, ratchet 3 joins with ratchet 9.The advantage of this scheme is when ratchet 3 separates with ratchet 9, and sour jujube bar 2 can be got back to last position freely.

Described entry needle 12 is crooked, and the advantage of this scheme is to make entry needle can enter into the tank filler sleeve of bearing, extend into the bearing race annex.

The needle point of described entry needle 12 is blunt, and the advantage of this scheme is to make entry needle not scratch bearing race and steel ball.

During use, in injection tube 10, inject grease, hold hander 1, pull spanner 6, spanner 6 utilizes lever principle to promote ratchet 3, ratchet 3 drives sour jujube bar 2 again and moves, and the push rod 11 of the mobile drive injector 5 of sour jujube bar 2 is extruded into the bearing race next door to the grease in the injection tube, and spanner stops during to position-limited shaft.Unclamp spanner 6, spanner 6 relies on the reaction force of return spring 4 to reset.Ratchet 3 is by the effect of reseting plate 8, near the ratchet 9 of sour jujube bar 2, to wait for the work for the second time of doing.After the grease in the injection tube 10 used up, driving lever 14 made ratchet 3 throw off ratchet 9 to pressing down downwards, unclamp block 13 again, just can take out injector 5 from hander 1, after injection tube 10 is filled grease, injector 5 hander 1 of packing into, proceed bearing and refuel again.
