Abstract
The utility model essentially discloses a kind of sleeve of with groove in step chain, its technical solution: sleeve both ends of the surface are equipped at least one groove, plane there are four being set on the excircle of sleeve surface, pass through the setting of groove, lubricating oil can for good and all be maintained or referred to be inhaled into the step chain kinematic pair hinge that sleeve and pin shaft are formed (siphonic effect), guarantee the abundant effectively lubricating of hinge inner, reduces wear of hinge, prolong the service life.
Description
Technical field
The utility model relates to step chain middle sleeve part technical field, with groove in especially a kind of step chain
Sleeve.
Background technique
Step chain belongs to carrier chain one kind, only specifically uses on escalator or moving sidewalk.Step chains
Item is used for escalator or moving sidewalk, and more and more performance requirements are endowed, and such as subway application requires ladder
Grade chain service life 10 years or more.In the prior art, in order to meet the requirements, CN201120556078.3 proposes that a kind of sealing is exempted from
Oiling step chain, existing sealing effect has to improve again lubricant effect and then to prolong the service life, but manufacturing cost it is higher and not
By market blanket approval；CN200920317582.0 proposes a kind of sleeve step chains with spiral shape oil storage tank, in sleeve
Oil storage tank is arranged in bore area, reinforces lubricating status when being rotatably assorted with pin shaft, reduces abrasion, prolongs the service life, but have
When note oil storage tank grease occur insufficient and the shortcomings that lack of lubrication occur.
Utility model content
The purpose of this utility model is to solve the problems, such as that the existing step chain service life is not grown, and improves lubricant effect, reduces set
Abrasion between cylinder and pin shaft, to prolong the service life.
In order to achieve the above object, the utility model is achieved through the following technical solutions: band ditch in a kind of step chain
The sleeve of slot, sleeve both ends of the surface are equipped at least one groove, set on the excircle of sleeve surface there are four plane.
The utility model is further, four planes are respectively the first plane, the second plane, third plane and fourth plane.
The utility model is further, the plane that is equipped with of the groove and outer round surface is perpendicular or parallel or inclined angle point
Cloth.
The utility model further, the trench depth is not more than 1.5mm, gap do not have to it is too big, prevent dust particles into
Enter hinge.
The utility model is further, the channel bottom is processed as R0.5mm round-corner transition.Due to inner plate and sleeve sheet
Body interference fit, interference power can be very big, and contact force is also corresponding very big, prevent stress from concentrating using round-corner transition.
The utility model has the beneficial effect that
By the setting of groove, it can for good and all maintain lubricating oil or refer to that being inhaled into the step chain that sleeve and pin shaft are formed transports
In dynamic pair hinge (siphonic effect), guarantees the abundant effectively lubricating of hinge inner, reduce wear of hinge, prolong the service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the floor map of the utility model；
Fig. 3 is four flat distribution maps of the utility model；
Fig. 4 is groove partial enlarged view in the utility model.
Appended drawing reference: 1, sleeve；2, groove；3, plane；31, the first plane；32, the second plane；33, third plane；34,
Fourth plane.
Specific embodiment
In conjunction with attached drawing, the utility model preferred embodiment is described in further details.
The sleeve of with groove, 1 both ends of the surface of sleeve are equipped at least one groove in a kind of step chain described in picture 1-4
2, it sets in 1 outer round surface of sleeve there are four plane 3, four planes 3 are respectively the first plane 31, the second plane 32, third
Plane 33 and fourth plane 34.By the setting of groove 2, it can for good and all maintain lubricating oil or refer to be inhaled into sleeve 1 and pin shaft shape
At step chain kinematic pair hinge in (siphonic effect), guarantee the abundant effectively lubricating of hinge inner, reduce wear of hinge, prolong
Long life.
The groove 2 and the plane that outer round surface is equipped be perpendicular or parallel or inclined angular distribution, the present embodiment it is attached
2 axis of groove is vertical with the plane that outer round surface is equipped in figure.
Referring to for attached drawing 4,2 depth of groove is not more than 1.5mm, and " a " is used to indicate depth in figure, and gap does not have to too
Greatly, prevent dust particles from entering hinge.The 2 bottom roundings R radius of groove is R0.5mm, due to inner plate and 1 ontology of sleeve
Interference fit, interference power can be very big, and contact force is also corresponding very big, prevent stress from concentrating using round-corner transition.
Above-described embodiment is only used for illustrating the inventive concept of the utility model, rather than to the utility model rights protection
Restriction, all non-essential modifications to the present invention made by this concept should all fall into the protection model of the utility model
It encloses.
