Description
technical field:
The utility model relates to a kind of step chains bearing pin lubricating structure, belongs to staircase technical field.
background technique:
in staircase technical field, the parts that step chains is run as traction step, it is one of most important stressed member of escalator, due to the particularity of stepchain configuration, general lubricating system is difficult to inside lubricant oil being entered into step chains, when not lubricating or lubricating insufficient, step chains and related components will sharply be worn and torn, thus whole staircase can be caused to produce potential safety hazard.
summary of the invention:
Technical problem to be solved in the utility model is: provide a kind of novel step chains bearing pin lubricating structure, solves the problem being difficult to inside lubricant oil being entered into step chains run in current staircase technical field.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of step chains bearing pin lubricating structure, includes step chains and the sleeve being arranged at two ends in step chains.
Form to multiple step chains is mutually permanently connected, further, in described sleeve, be fixedly connected with cylindrical bearing pin,
Step chains inside is entered in order to lubricant oil can be made, again further, the top of described bearing pin is provided with circular vertical core, and the surface of described bearing pin is provided with circular cross-drilled hole, described circular vertical core and circular cross-drilled hole are interconnected, and described circular vertical core place is provided with grease fitting.
In order to be fixed in step chains by stable for bearing pin, further, the surface of described bearing pin is provided with groove structure, and described groove is provided with clip.
Compared with prior art, usefulness of the present utility model is: provide a kind of novel step chains bearing pin lubricating structure, use circular vertical core and the cross one another structure of circular cross-drilled hole, lubricant oil is drained in step chains, solve the problem that step chains is not easily lubricated, and structure is simple, method is unique, respond well.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is general assembly drawing of the present utility model.
In figure: 1, step chains; 2, sleeve; 3, bearing pin; 4, circular vertical core; 5, circular cross-drilled hole; 6, grease fitting; 7, groove; 8, clip.
embodiment:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail: a kind of step chains bearing pin lubricating structure according to Fig. 1, include step chains 1 and the sleeve 2 being arranged at two ends in step chains 1, 2 li, described sleeve is fixedly connected with cylindrical bearing pin 3, the top of described bearing pin 3 is provided with circular vertical core 4, the surface of described bearing pin 3 is provided with circular cross-drilled hole 5, described circular vertical core 4 and circular cross-drilled hole 5 are interconnected, described circular vertical core 4 place is provided with grease fitting 6, the surface of described bearing pin 3 is provided with groove 7 structure, described groove 7 place is provided with clip 8.
During use, sleeve 2 in multiple step chains 1 is alignd mutually, be put in sleeve by bearing pin 3 again, be placed to by clip 8 in groove 7, such bearing pin 3 just can firmly be placed in staircase structure, again grease fitting 6 is placed in circular vertical core 4, when staircase is in movement process time, lubricant oil just from grease fitting 6 out, enters into circular vertical core 4, enter into circular cross-drilled hole 5 again, flow out from circular cross-drilled hole 5 and enter into step chains.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
