Abstract
The invention discloses a step shaft sleeve for a step shaft of an escalator, and belongs to the technical field of escalator members. The step shaft sleeve comprises a shaft sleeve body, wherein an oil groove is formed on the inner wall of the shaft sleeve body. The step shaft sleeve is characterized in that: the oil groove is extended from one end of the inner wall of the shaft sleeve body to the other end of the inner wall of the shaft sleeve body in a spiral state; and an oil filling hole which is communicated with the oil groove and is used for filling lubricating grease into the oil groove is formed in the shaft sleeve body. The invention has the advantages that: the inner wall of the shaft sleeve body can be comprehensively lubricated; the oil groove is spiral, so that the length of the oil groove is remarkably increased, the oil storage amount is remarkably increased, and the lubricating effect between the shaft sleeve body and the step shaft is remarkably improved; and the oil filling hole which is communicated with the oil groove is formed in the shaft sleeve body, so that the lubricating grease can be filled into the oil groove at random, the shaft sleeve body is not required to be disassembled from the step shaft during oil filling compared with that of the prior art, and oil is extremely convenient to supplement.
Description
Technical field
The invention belongs to escalator component technology field, be 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
task of the present invention 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.
task of the present invention 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.
technical scheme provided by the invention 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 escalator step axle usefulness of the present invention.
Fig. 2 is the cutaway view of Fig. 1.
Fig. 3 is an application examples scheme drawing of the present invention.
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 technical spirit of the present invention and beneficial effect 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 present invention program, any according to the present invention design done only for pro forma but not substantial equivalent transformation all should be regarded as technical scheme category of the present invention.
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 technical scheme of the present invention: 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 present invention program 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 present invention program 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 axle sleeve body 1 of the present invention; 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 present invention 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
