Description

Lubricating oil-filling type bearing

Technical Field

The utility model relates to a bearing technical field specifically is a lubricated oil type bearing that mends.

Background

In the existing bearing, because the high-speed operation of roller makes the grease consumption too big, when the grease consumption is totally spent, the friction torque between roller and interior outer lane and the holder rises by a wide margin for the holistic operating rate of bearing descends by a wide margin, and can influence the life of bearing, and the bearing can lead to the temperature rise in the bearing because the grease consumption is totally spent, thereby influences the operation of bearing, further reduction the life of bearing.

SUMMERY OF THE UTILITY MODEL

The utility model provides a lubricated oil type bearing that mends leads to the problem that roller friction torque rises totally for grease consumption among the solution prior art.

The utility model provides a lubricated oil supplementation type bearing, includes inner circle, outer lane and roller, inner circle and outer lane combination are formed with and supply roller pivoted to roll the chamber, including the oil supplementation ring, set up on the outer lane and supply oil supplementation ring male annular oil supplementation groove, the annular goes out the oil groove still seted up on the outer lane, annular goes out the oil groove and rolls the chamber and switches on the setting, the cavity has seted up the grease storage chamber on the oil supplementation ring, the oil outlet chamber that a plurality of and grease storage chamber switched on is seted up to cavity on the oil supplementation ring, it is provided with out the oil piece to go out the intracavity slip, set up the opening that supplies out the oil piece to expose or retract on going out the oil chamber, it has the oil outlet who is used for transmitting the grease to switch on the oil piece, it inserts annular oil outlet groove and realizes that the grease passes through the oil outlet and flows in the annular oil outlet groove.

The technical scheme is adopted, and the method has the advantages that: before an operator inserts the oil supplementing ring into the annular oil supplementing groove, the oil outlet block retracts into the oil outlet cavity, the operator can conveniently insert the oil supplementing ring into the annular oil supplementing groove without colliding with the oil outlet block, when the oil supplementing ring is inserted into the annular oil supplementing groove, the oil outlet block slides in the oil storage cavity and penetrates out of the annular oil outlet groove, at the moment, grease flows into the oil outlet hole from the grease storage cavity and then flows into the annular oil outlet groove through the oil outlet hole, the grease is in the annular oil outlet groove, and when a roller runs, the grease flows into the roller cavity from the annular oil outlet groove to coat the surface of the roller, so that the friction torque of the roller cannot rise due to the depletion of the grease, the service life of the bearing is further prevented from being reduced, the grease coating is performed on the surface of the roller, and the running efficiency of the bearing is prevented from being influenced by the excess grease rolling in the bearing; the oil supplementing ring is detachably arranged in the annular oil supplementing groove, so that an operator can supplement oil in the bearing without disassembling the bearing, the cost consumption caused by replacing the bearing is reduced, the oil supplementing time in the bearing is also reduced, the service efficiency of the bearing is greatly improved, and the service life of the bearing is greatly prolonged; the annular oil outlet groove enables grease to be stored in the annular oil outlet groove and not to leak out of the bearing, and the grease on the surface of the roller can be uniformly coated.

The utility model discloses further set up: store up and be connected between fat chamber and the oil outlet chamber and switch on there is the through-hole, the protruding lug that is used for inserting the through-hole that has on the piece of producing oil, the oil outlet extends to the lug and passes the lug setting, lug and through-hole size looks adaptation.

The technical scheme is adopted, and the method has the advantages that: lug and through-hole size looks adaptation for during the grease can not flow out the oil cavity when the lug inserts the through-hole, but in smooth follow oil outlet flow to annular oil groove, avoid the grease to cause the influence to the piece of producing oil, the waste of further reduction grease, and when the piece of producing oil slides in the intracavity of producing oil, the lug inserts in the through-hole makes the inflow oil outlet that the grease of storage fat intracavity can be better downthehole, improves the efficiency of producing oil.

The utility model discloses further set up: the oil outlet hole is characterized in that a film used for sealing the grease storage cavity is arranged on the inner wall of the oil outlet hole, and the protruding block breaks the film when the oil outlet block slides in the oil outlet cavity to form grease which flows into the oil outlet hole from the grease storage cavity.

The technical scheme is adopted, and the method has the advantages that: the setting of film prevents the leakage of grease in the grease storage cavity before the oil supply ring inserts annular oil supply groove, and the lug bursts the film when the piece that produces oil withdraws out the oil pocket and makes the grease begin to flow to the oil outlet, and operating personnel will mend the oil ring and insert annular oil supply groove this moment and avoid the grease to outwards reveal from the oil outlet.

The utility model discloses further set up: the oil outlet cavity is provided with a tensioning ring which is used for sliding and resetting the oil outlet block in the oil outlet cavity near the oil outlet hole, the outer wall of the oil outlet block is abutted against the tensioning ring, and the tensioning ring is provided with a through hole for the lug to pass through.

The technical scheme is adopted, and the method has the advantages that: when an operator presses the oil outlet block to enable the oil outlet block to retract into the oil outlet cavity, the outer wall of the oil outlet block abuts against the tensioning ring and tightly presses the tensioning ring, when the oil supplementing ring is inserted into the annular oil supplementing groove, the tensioning ring starts to rise and enables the oil outlet block to reset in the oil outlet cavity, the oil outlet block extends out and is inserted into the annular oil outlet groove, the oil outlet block can be guaranteed not to retract into the oil outlet cavity when a bearing operates, and the oil outlet block can smoothly transmit grease into the annular oil outlet groove.
