Abstract
The utility model discloses centripetal rolling bearing comprises the chain of buckling into "gear" form between outer lane, inner circle, roller, the interior outer lane, and the chain has the dismantled and assembled chain link of even number, embolias the roller of opening the centre bore on the chain link axle to the roller that forms "tooth top" portion and "tooth root" portion on the chain contacts with outer lane, the interior raceway of circling respectively.
Description
The utility model relates to a kind of bearing that rotates usefulness, especially a kind of radial antifriction bearing of being made up of outer ring, inner ring, roller.
Existing radial antifriction bearing is made up of outer ring, inner ring, roller and roller cage that metallic material is made usually, and roller cage is separated roller, is evenly arranged in the raceway of inside and outside circle composition.This class radial antifriction bearing, its roller rolling surface contacts simultaneously with the raceway of inside and outside circle, and roller rolls a week, and the roller rolling surface will be subjected to the friction of two weeks.For reducing friction loss, must use oil lubrication between roller and raceway, roller and retainer, but friction can heating, will lubricant oil therebetween constantly be reduced, wearing and tearing between the metal increase, for this reason, must be in time or often inject lubricant oil; This class bearing is under sealing condition or specific environment, and it is often unable to do what one wishes to add lubricant oil.Lack lubricated bearing and can make the wearing and tearing aggravation, cause bearing loosening, damaged or " killing ", and can not reprocess, become scrap iron; In addition, in installing or turning round, during as if generation inner ring or outer ring fracture,, also whole bearing have to be scrapped because of the user can't keep in repair.
The purpose of this utility model is to improve the structure of above-mentioned bearing, and a kind of dismounting, easy to maintenance is provided, and long service life need not be added the radial antifriction bearing of lubricant oil in the running.
Technical solution of the present utility model is, all circumferentially extendings become the gear shape structure in inner ring periphery or outer ring, this gear shape structure has the braces of n circumference uniform distribution, each roller and braces flexibly connect, roller after the connection be in the coaxial circumference in inner ring or outer ring on, and contact with raceway on outer ring or the inner ring.When the outer ring is fixed, when inner ring rotates, roller rolls on the raceway of outer ring under the braces on the inner ring drives, roller both revolved round the sun, and did rotation again; Perhaps, the inner ring of rotation relies on the frictional force of its raceway, and the roller that the drive outer ring connects on the braces rotates, and roller is only done rotation.
Above-mentioned braces, it axially has and the corresponding groove of roller size, and the both sides of groove are drilled with a pair of coaxial through-hole, and the roller that is contained in the groove also has corresponding center hole and described coaxial aperture to aim at, in the hole that is aligned with each other bearing pin is housed, the position that this bearing pin stretches out the braces limit has a card yellow.
Above-mentioned roller or inner ring, outer ring adopt wear-resisting material to make, as polytetrafluoroethylene or other macromolecular material.
The radial antifriction bearing of said structure, the interior rotation surface of the rolling surface of its roller and its center hole is separated, when roller rolls a week, rolling surface is only done the friction in a week, interior rotation surface equally only rubs a week, thereby the wearing and tearing of rolling surface are little, and utilizes the antifriction performance of macromolecular material polytetrafluoroethylene, need not add oil lubrication in the use, prolong working life; Next is that roller and braces employing removably connect, and when wearing and tearing or damage, can change corresponding part easily voluntarily, continues to use, and will not scrap processing by whole bearing work, thereby can be a large amount of metals resources of country's saving.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the utility model first embodiment's a structural representation.
Fig. 2 is that sectional view is looked on the left side of Fig. 1.
Fig. 3 is second embodiment's a structural representation.
Fig. 4 is that the left side of Fig. 3 is looked and cutd open figure.
As shown in Figure 1, the utility model comprises outer ring 1, inner ring 5, a n roller 2.Outer periphery at inner ring is extended into gear shape structure 4, this gear shape structure has the braces 3 of n circumference uniform distribution, braces have axially that (roller can be a ball with roller, also can be roller, present embodiment adopts ball) the corresponding groove of diameter, referring to Fig. 2, the both sides of groove are drilled with a pair of coaxial through hole 8, the roller 2 that is contained in the groove also has corresponding center hole 9 and described coaxial aperture 8 to aim at, and a "T"-shaped bearing pin 7 is housed in the hole that is aligned with each other, and roller can rotate around bearing pin; At the bearing pin afterbody that stretches out braces a jump ring 11 is arranged, in case bearing pin breaks away from coaxial aperture in bearing operation and roller is scattered.Each roller 2 is with after braces 3 is connected, locate one with the coaxial circumference of inner ring 5 on, at this moment roller 2 contacts with the raceway 6 of outer ring 1.In the both sides of inner ring spoke 4, the dust-proof cover 10 that cooperates with the outer ring is housed respectively.
When outer ring 1 is fixing, when inner ring 5 rotates, rotate with the braces 3 of inner ring 5 consubstantialities, when braces drove roller 21 raceway 6 rolls along the outer ring, roller rotated around bearing pin.
Also can be according to above-mentioned principle, be designed to the radial antifriction bearing of another kind of structure, its structure as shown in Figure 3, in this structure, all circumferentially extendings become internal tooth wheel shape structure 14 in the outer ring 1, this internal tooth wheel shape structure also has the braces 13 of n circumference uniform distribution, and braces and roller 2 flexibly connect, and its concrete structure, relation are referring to shown in Figure 4.Axially having and roller (this example is a ball) the corresponding groove of diameter of this braces 13, the both sides of groove are drilled with a pair of coaxial through hole 8, the roller 2 that is contained in the groove also has corresponding center hole 9 and described coaxial aperture to aim at, "T"-shaped bearing pin 7 is housed in the hole that is aligned with each other, jump ring 11 is arranged at the bearing pin afterbody that stretches out braces.Roller be on the coaxial circumference in outer ring after braces is connected, and contact with inner ring 5 raceways 15.For anti-foreign matter enters in the revolute pair, be embedded with dust-proof cover 10 respectively in the both sides of outer ring.
The utility model radial antifriction bearing long service life, wearing and tearing backs are easy to maintenance, need not add lubricant oil in the running, are applicable to the machinery of various rotations.
