Abstract
The utility model discloses a step chain with a filling cup. The step chain with the filling cup comprises a plurality of chain links, wherein adjacent chain links are connected through pin shafts and outer chain plates, the chain links comprise inner chain plates, sleeves and rollers, the sleeves are sleeved outside the pin shafts, the rollers are sleeved outside the sleeves, the two inner chain plates are respectively sleeved on the two ends of the sleeve, the two ends of the pin shafts are connected with the outer chain plates, the filling cup is arranged on one end of the pin shafts, the filing cup is communicated with an axial blind hole which is arranged on the pin shafts, and the axial blind hole is communicated with an oil storage slot which is arranged between the sleeves and the pin shafts through a plurality of radial holes A. The step chain with the filling cup increases lubrication reliability in routine maintenance in a packingless step chain, reduces attrition of chains, and prolongs service life of the chains.
Description
Technical field
The utility model belongs to chain drive technology field, particularly relates to a kind of step chain with priming cup.
Background technique
At present, step chain commonly used generally adopts the lubricating system of drop lubrication, splash lubrication and oil pump oil jet lubrication etc.Above lubricating system is all larger to the breakage of lubricant oil, and not sealing between the chain hinged place, and dust easily gathers, and has reduced lubricated reliability, is prone to lubricated situation not in place, increases the wearing and tearing of chain, reduces the working life of chain.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of step chain with priming cup, in packingless step chain, increases reliability lubricated in regular maintenance, reduces the wearing and tearing of chain, improves the working life of chain.
To achieve the above object, the utility model has adopted following technological scheme:
A kind of step chain with priming cup, comprise a plurality of chain links, connect by bearing pin, outer plate between adjacent link, described chain link comprises inner plate, sleeve and roller, jacket casing is located at outside bearing pin, sleeve outside suit roller, two inner plates are set in sleeve two ends, the bearing pin two ends are connected with outer plate, one end of described bearing pin is equipped with priming cup, this priming cup is communicated with axial blind hole on being located at bearing pin, and this axial blind hole is communicated with oil storage tank between sleeve and bearing pin by several radial holes A.
As preferably, described oil storage tank is by forming by two flat horizontal surfaces and the sleeve lining that mills bearing pin intermediate portion gained.Further preferred, described radial hole A is perpendicular to its flat horizontal surface that connects, and staggers mutually in the two radial hole A positions at flat horizontal surface place, two of up and down.Guaranteed like this bulk strength of chain.
As preferably, described sleeve is provided with several radial holes B, and this radial hole B is communicated with and is covered by roller with oil storage tank on bearing pin.
As preferably, described bearing pin two ends and the riveted joint of both sides outer plate are fixing.
The utility model is owing to having adopted above technological scheme, the lubricating grease that injects by priming cup, can be effectively oil duct through the bearing pin center flow into hinged place between bearing pin and sleeve, the kinematic pair of chain is effectively lubricated, reduce the wearing and tearing of chain, improve the working life of chain.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made a detailed explanation.
Embodiment 1:
as Fig. 1, Fig. 2, a kind of step chain with priming cup shown in Figure 3, comprise a plurality of chain links, pass through bearing pin 3 between adjacent link, outer plate 2 connects, described chain link comprises inner plate 1, sleeve 5 and roller 6, sleeve 5 is set in bearing pin 3 outsides, sleeve 5 outside suit rollers 6, two inner plates 1 are set in sleeve 5 two ends, bearing pin 3 two ends are connected with outer plate 2, one end of described bearing pin 3 is equipped with priming cup 4, this priming cup 4 is communicated with axial blind hole 31 on being located at bearing pin 3, this axial blind hole 31 is communicated with oil storage tank 33 between sleeve 5 and bearing pin 3 by several radial holes A32.Described sleeve 5 is provided with several radial holes B51, and this radial hole B51 is communicated with and is covered by roller 6 with oil storage tank 33 on bearing pin 3.Described bearing pin 3 two ends and 2 riveted joints of both sides outer plate are fixing.Described oil storage tank 33 is by forming by two flat horizontal surfaces and sleeve 5 inwalls that mill bearing pin 3 intermediate portion gained.Described radial hole A32 is perpendicular to its flat horizontal surface that connects, and staggers mutually in the two radial hole A32 positions at flat horizontal surface place, two of up and down.
In the present embodiment, formed by the oil hole at the oil storage tank of the oil duct of priming cup, bearing pin inside, bearing pin medium position and sleeve middle part one oil leab effectively.Priming cup coordinates for being pressed into the radial fit of bearing pin, and bearing pin middle part is milled the flat filament position and be can be used as an interim oil storage tank, increases the lubricating grease that injects the step chain kinematic pair, has so just formed a semi-enclosed oiling passage.During regular maintenance, lubricating grease injects through priming cup 4, oil duct by way of axial blind hole 31 and radial hole A32 formation, arrive oil storage tank 33, make bearing pin 3 and the hinged place of sleeve 5 obtain effectively lubricating, lubricating grease is through extruding, by the hinged place between radial hole B51 inflow sleeve 5 and roller 6, thereby the kinematic pair that makes step chains has obtained effectively lubricated, reduces the wearing and tearing of chain, improves the working life of chain.
It is emphasized that: above is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
