Abstract
A step axle sleeve for a step axle of an escalator belongs to the technical field of escalator elements. The step axle sleeve comprises an axle sleeve body, wherein an oil groove is formed in the inner wall of the axle sleeve body. The step axle sleeve is characterized in that the oil groove spirally extends from one end of the axle sleeve body to the other end on the inner wall of the axle sleeve body, and an oil filling hole communicated with the oil groove and used for filling lubricating grease in the oil groove is formed in the axle sleeve body. The step axle sleeve has the advantages as follows: the inner wall of the axle sleeve body can be lubricated completely; as the oil groove is spiral, the length is remarkably prolonged, the oil reserve is remarkably increased, and the lubricating effect between the axle sleeve body and the step axle is remarkably improved; and as the oil filling hole communicated with the oil groove is formed in the axle sleeve body, the lubricating grease can be filled in the oil groove at random, which is different from the prior art in which an axle sleeve body is required to be dismounted from a step axle when oil filling is performed, so that oil make-up is very convenient.
Description
Technical field
The utility model belongs to escalator component technology field, is specifically related to a kind of step axle sleeve of escalator step axle usefulness
Background technology
such as industry the reason of knowledge; Escalator step is set on (each step has a step axle) on the step axle through step axle; The two ends of step axle are connected with conduction chain respectively, drive step axle by conduction chain, thereby make the step motion.It is thus clear that; The carrying of escalator step passes to step axle and conduction chain (industry is also claimed step chain) through the step axle sleeve; When step runs to up and down the section of turning to; The friction that can rotate between the inwall of step axle sleeve and the step axle in order to protect step axle and step axle sleeve, so needs to guarantee have good lubricating effect between the inwall of step axle sleeve and the step axle.Normally in the step axle sleeve, offer oil groove, apply grease in oil groove is so that step axle sleeve inside face is in lubricating status.
The structure of the step axle sleeve of the escalator step axle usefulness in
prior art is as shown in Figure 4, comprises axle sleeve body 1, on the inwall of axle sleeve body 1, offer oil groove 11, and oil groove 11 is a straight trough.During use, apply grease in oil groove.Yet because the anglec of rotation of step axle is limited, add that the oil groove 11 interior oil reserves of vertical bar shape are limited, therefore in use can not show the lubricant effect of people's expectation.Especially; Because the self structure of axle sleeve body 1 lacks reasonableness; For example owing to lack oil hole; Therefore can't refuel to oil groove 11, and step axle sleeve axle sleeve body 1 moved apart from step axle can only or claim with the mode of time-based maintenance the time, implement repairing (supplemental lubrication grease) by means of maintenance.Therefore be unfavorable in daily use, playing persistence protection to step axle and axle sleeve body 1.
In view of above-mentioned prior art, be necessary to improve, to this, the applicant has done useful design, below the technical scheme that will introduce under this background, produce
Summary of the invention
The task of
the utility model be to provide a kind of inwall that helps to make the axle sleeve body lubricated comprehensively and use improve and step axle between good lubricated matching relationship and avoid undermining axle sleeve body and step axle, need not the axle sleeve body is moved apart that step axle is implemented repairing and the step axle sleeve of escalator step axle usefulness of using the comfort feature of embodiment repairing.
The task of
the utility model is accomplished like this; A kind of step axle sleeve of escalator step axle usefulness; Comprise the axle sleeve body; Offer oil groove on the inwall of this axle sleeve body, be characterised in that: described oil groove extends to the other end of the inwall of axle sleeve body with spiral status from an end of the inwall of axle sleeve body, and on the axle sleeve body, also offers the oil hole that is used for oil groove is injected lubricating grease that communicates with said oil groove.
The technical scheme that
the utility model provides is owing to change the oil groove of the vertical bar shape in the prior art screw-shaped into and extend to the oil groove of the other end from an end of the inwall of axle sleeve body, thereby can make the inwall of axle sleeve body lubricated comprehensively; Because oil groove is a spiral fashion, so the length significant prolongation, oil reserve significantly increases, and the lubricant effect between axle sleeve body and the step axle is significantly improved; Owing on the axle sleeve body, offered the oil hole that communicates with oil groove, therefore can inject lubricating grease to oil groove randomly, when oiling, the axle sleeve body is unloaded from step axle the prior art and need not to resemble, so repairing is very convenient.
Description of drawings
Fig. 1 is the constructional drawing of the step axle sleeve of the utility model escalator step axle usefulness.
Fig. 2 is the cutaway view of Fig. 1.
Fig. 3 is the application examples scheme drawing of the utility model.
Fig. 4 is the constructional drawing of the step axle sleeve of the escalator step axle usefulness in the prior art.
The specific embodiment
can be expressly understood the technical spirit and the beneficial effect of the utility model more for the inspector that the makes Patent Office especially public; The applicant general elaborates with the mode of embodiment below; But the description to embodiment all is not the restriction to the utility model scheme, any according to the utility model design done only for pro forma but not substantial equivalent transformation all should be regarded as the technical scheme category of the utility model.
Fig. 1 and Fig. 2 are asked for an interview in
, and the step axle sleeve that provides comprises an axle sleeve body 1, offer oil groove 11 at the inwall of this axle sleeve body 1.Main points as the technical scheme of the utility model: aforesaid oil groove 11 extends to an outer end of the inwall of axle sleeve body 1 from an end of the inwall of axle sleeve body 1 with spiral status; It is thus clear that the oil groove 11 that the utility model scheme provides is the helical oil groove more than 360 °; Can make the inwall of axle sleeve body 1 obtain lubricating grease all sidedly; After on axle sleeve body 1 is installed to by the step axle 21 of step shown in Figure 32, can and step axle 21 between show good lubricating effect.Again, the utility model scheme on axle sleeve body 1, also offer one run through the wall body of axle sleeve body 1 oil hole 12, oil hole 12 communicates with oil groove 11, and preferably oil hole 12 is opened in the middle part of the length direction of axle sleeve body 1.So structure can be passed through oil hole 12 make-up oil in oil groove 11 as required, and need not supplemental lubrication grease under the state that axle sleeve body 1 is unloaded from step axle 21, and is therefore very convenient.
Fig. 3 is asked for an interview in
, in this Fig. 3, has provided the step 2 of escalator, and the two ends of step 2 respectively are connected with step axle 21 through the axle sleeve body 1 of the utility model; And the two ends of step axle 21 respectively are connected with conduction chain 3 (also claiming terraced chain); Under the motion of pair of traction chain 3, drive steps 2 motions, when step 2 moves to hypomere, when promptly moving to upper and lower flex point through step axle 21; Can show strong pivoting friction between axle sleeve body 1 and the step axle 21; Yet because the utility model offers screw-shaped oil groove 11 at the inwall of axle sleeve body 1, make the length significant prolongation of oil groove 11, oil reserve significantly increases; The inwall of axle sleeve body 1 and the whole lubricant effect between the step axle 21 have been ensured; Both helped to protect axle sleeve body 1, and also helped protecting step axle 21, therefore can yet be regarded as is a ultimate attainment technical scheme.When will be to oil groove 11 repairings, then need not axle sleeve body 1 is unloaded in step axle 21, therefore help the convenience of daily maintenance
