Abstract
The utility model provides a hoisting chain which is used for a escalator or a moving pavement; the chain consists of a plurality of chain link units; every chain link unit comprises a pin, an pin sleeve, a roller, external chain pieces and internal chain pieces; the external chain pieces are equipped with axial pores, the pin is penetrated through the pin sleeve to pivot-connect the two ends of the pin sleeve with the axial pores which are arranged on the external chain piece; the internal chain pieces are also equipped with axial pores and the two ends of the pin are connected with the axial pores which are arranged on the internal chain piece; the roller is fit over the pin sleeve between two internal chain pieces; the utility model is characterized in that the pin sleeve is equipped with a horizontal diversion groove and a radial through hole; with the diversion groove and the through hole, lubricant can flow to the contact surface of the pin and the pin sleeve through interlaced grooves and holes in use and in this way, the relatively moving parts of the contact part of the pin and pin sleeve can be fully lubricated and the service life of the hoisting chain can be greatly prolonged.
Description
Technical field
The utility model relates to a kind of chain, relates in particular to the traction chain that escalator or moving sideway are used.
Background technique
In the prior art, the traction chain of escalator or moving sideway lubricated has two kinds of methods: oil lubrication and grease lubrication.When adopting oil lubrication, by manually or automatically giving the regular oil dripping of chain, rely on the flowability of oil, flow in the feasible micro-gap of oil between the part of chain that constantly replenishes, thereby the contact surface to relative movement is lubricated, and plays and improves the chain effect in working life.When adopting grease lubrication, guarantee that by regular each chain link supplemental lubrication fat the contact surface of chain relative movement is in lubricating status to chain.
The method of oil lubrication is along with the increase of the Breaking load of chain, the physical dimension of part increase, cause the area of contact between part to increase, increase---the especially increase of width as the diameter and the width of axle sleeve, make lubricant oil can not or seldom enter the neutral position of part contact position, thereby influence the working life of chain.The method of grease lubrication does not then have operability for reel chain, will need long time because whenever replenish a lubricating grease to chain, and cost of upkeep is too high, and has a strong impact on the normal use of escalator or moving sideway.
Therefore, designing the novel traction chain of a kind of escalator or moving sideway, can make lubricant oil enter into chain inside and be lubricated, will be a technical requirements height, important topic that social effect is big.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and the traction chain of a kind of escalator or moving sideway is provided, and can make lubricant oil be easy to enter into chain inside, thereby chain is carried out sufficient lubrication.
The purpose of this utility model is achieved through the following technical solutions:
The traction chain of escalator or moving sideway, described chain is made of some link units, each link units comprises bearing pin, axle sleeve, roller, outer chain sheet and inner chain sheet, outer chain sheet is provided with axis hole, bearing pin passes axle sleeve and two ends is articulated on the axis hole of outer chain sheet, is provided with axis hole on the inner chain sheet equally, and the axle sleeve two ends are articulated on the axis hole of inner chain sheet, be with roller on the axle sleeve between two inner chain sheets, it is characterized in that: described axle sleeve is provided with transverse channels and radial direction through hole.
Purpose of the present invention can also come further to realize by the following technical programs:
The traction chain of aforesaid escalator or moving sideway, wherein, the transverse channels of described axle sleeve and radial direction through hole intersect.
The traction chain of aforesaid escalator or moving sideway, wherein, the quantity of transverse channels and radial direction through hole is two on each axle sleeve.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in: because the existence of guiding gutter and through hole, make lubricant oil can successfully enter into the contact surface of axle and axle sleeve by staggered groove and hole, thereby make the shaft parts of relative movement and the contact position of axle sleeve obtain sufficient lubrication, prolonged the working life of traction chain greatly.This design is succinct practical, is suitable in the industry and promotes the use of.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: the utility model stereochemical structure decomposing schematic representation;
Fig. 2: the enforcement schematic representation of transverse channels and radial direction through hole on the axle sleeve;
Fig. 3: another enforcement schematic representation of transverse channels and radial direction through hole on the axle sleeve.
The implication of each reference character among the figure:
Roller-1, axle sleeve-2, bearing pin-3, inner chain sheet-4a, outer chain sheet-4b; Transverse channels-5, radially pod apertures-6.
Embodiment
As shown in Figure 1, the traction chain of escalator or moving sideway, chain is made of some link units, each link units comprises bearing pin 3, axle sleeve 2, roller 1, outer chain sheet 4b and inner chain sheet 4a, outer chain sheet 4b is provided with axis hole, and bearing pin 3 passes axle sleeve 2 and two ends is articulated on the axis hole of outer chain sheet 4b, is provided with axis hole on the inner chain sheet 4a equally, axle sleeve 2 two ends are articulated on the axis hole of inner chain sheet, are with roller 1 on the axle sleeve between two inner chain sheets 2; Wherein, axle sleeve 2 is provided with transverse channels 5 and radial direction through hole 6 (Fig. 2 and shown in Figure 3), and the transverse channels 5 of axle sleeve intersects with radial direction through hole 6,, the quantity of transverse channels 5 and radial direction through hole 6 is two on each axle sleeve.
The axial diversion groove 5 of chain axle sleeve and the radially pod apertures 6 that intersects with it constitute guide channel, make the contact surface that lubricant oil can enter into bearing pin 3 and axle sleeve 2 smoothly by staggered groove and hole, thereby make the bearing pin 3 of relative movement and the contacting part potential energy of axle sleeve 2 obtain sufficient lubrication, prolong the working life of traction chain to greatest extent.
In sum, the traction chain of the utility model escalator or moving sideway, the method by continuous make-up oil is carried out effectively lubricating to the contact surface of each chain link relative movement part of traction chain.This design is succinct practical, is suitable in the industry and promotes the use of, and has good economic benefits and social benefit.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
