Abstract
The utility model relates to a kind of hermetically sealed roller ball bearing chain, and comprise outer plate, inner plate, bearing and bearing pin, bearing inner race is fixed on bearing pin, bearing inner race both sides have seal lubrication pad respectively and seal lubrication cushion cover on bearing pin.Above-mentioned chain can either reduce the frictional force in roller using process, it is made in operation process, to produce less wearing and tearing than other types roller, and larger weight can be born, transmission accuracy and transmission power can be guaranteed again, advantage: one is not only significantly reduce the frictional force in roller using process, and bearing roller produces wearing and tearing hardly in operation process, thus when bearing larger load-carrying, can guarantee that transmission accuracy and transmission power are not impaired; Two is adopt seal lubrication pad as roller bearing seal, not only good seal performance, and lubricity is good.
Description
Technical field
The utility model relates to a kind of frictional force that can either reduce in roller using process, it is made in operation process, to produce less wearing and tearing than other types roller, and larger weight can be born, the hermetically sealed roller ball bearing chain of transmission accuracy and transmission power can be guaranteed again, belong to chain and manufacture field.
Background technique
The applicant is all, and in first patent CN202091427U, title " bearing roller chain ", it comprises chain, and on the bearing pin in described chain, cover has bearing, and jacket casing is on bearing pin.Advantage: one is the frictional force greatly reducing chain; Two is the bearing capacities that effectively improve chain; Three is to rotate flexibly, freely.But because bearing is not directly be fixed on bearing pin, but be fixed on sleeve, jacket casing is on bearing pin, quality of fit error is not only caused to increase, affect transmission accuracy, and once relatively rotate between sleeve and bearing pin, then directly have influence on the efficiency of transmission power.
Model utility content
Purpose of design: avoid the deficiency in background technique, if a kind of frictional force that can either reduce in roller using process, it is made in operation process, to produce less wearing and tearing than other types roller, and larger weight can be born, the hermetically sealed roller ball bearing chain of transmission accuracy and transmission power can be guaranteed.
Design proposal: in order to realize above-mentioned purpose of design.1, bearing inner race is directly fixed in the design on bearing pin, is one of technical characteristics of the present utility model.The object of such design is: the inner ring due to bearing is directly socketed with bearing pin and is fixedly connected with, and inner ring and bearing pin situation in relative rotation can not occur, so both have the feature that quality of fit is high, in turn ensure that transmission accuracy and transmission agency unaffected; Secondly, owing to eliminating housing part, both decrease mismatch error, again reduced manufacture cost, solve the defect that the caused quality of fit that to rub between sleeve and bearing pin is low simultaneously.2, two pieces are enclosed within bearing inner race both sides and have seal lubrication pad respectively and the design of seal lubrication cushion cover on bearing pin, are technical characteristicss two of the present utility model.The object of such design is: because graphite high-abrasive material can work and without lubricant oil work in 200 ~ 2000 DEG C of temperature under very high rotational velocity, the utility model adopts graphite to do wear-resisting lubricating pad and for sealing and the side of lubricating bearings Internal and external cycle, circumferential surface and end face, both the reliable sealing to bearing side, circumferential surface had been served, have again good lubricity, bearing is reliably working under high speed loaded state.3, bearing outer ring is the design of indent channel-shaped structure, is technical characteristics four of the present utility model.The object of such design is: because the aperture of groove-like outer ring and inner ring external diameter are seamless Spielpassung, it can meet the assembling between inner ring and outer ring, bearing bracket stand can be built in groove again, thus plays the protective action to bearing bracket stand.
Technological scheme: a kind of hermetically sealed roller ball bearing chain, comprise outer plate, inner plate, bearing and bearing pin, bearing inner race is fixed on bearing pin, bearing inner race both sides have seal lubrication pad respectively and seal lubrication cushion cover on bearing pin.
The utility model is compared with background technique, one is not only significantly reduce the frictional force in roller using process, and bearing roller produces wearing and tearing hardly in operation process, thus when bearing larger load-carrying, can guarantee that transmission accuracy and transmission power are not impaired; Two is adopt seal lubrication pad as roller bearing seal, not only good seal performance, and lubricity is good.

Embodiment
Embodiment 1: with reference to accompanying drawing 1-3.A kind of hermetically sealed roller ball bearing chain, comprise outer plate 1, inner plate 2, bearing 3 and bearing pin 5, bearing 3 inner ring 32 is fixed on bearing pin 5, and bearing 3 inner ring 32 both sides have seal lubrication pad 4 respectively and seal lubrication pad 4 is enclosed within bearing pin 5.Bearing 3 outer ring 31 is in indent channel-shaped structure, and its preparation process system prior art, is not described herein at this.Seal lubrication pad 4 is flange-like structure and flange boss circumferential surface 41 and bearing outer ring 31 inner headed face touch, and flange touches along face 42 and bearing outer ring 31 side, and flange raised head face and bearing inner race 32 side touch.Seal lubrication pad 4 adopts graphite to make, and its preparation process system prior art, is not described herein at this.
It is to be understood that: although above-described embodiment to be contrasted detailed text description to mentality of designing of the present utility model; but these text descriptions; just the simple text of the utility model mentality of designing is described; instead of the restriction to the utility model mentality of designing; any do not exceed the utility model mentality of designing combination, increase or amendment, all fall in protection domain of the present utility model.
