Abstract

The utility model provides a low-maintenance chain which comprises outer chain boards, inner chain boards, a roller and a pin shaft, wherein the outer chain boards are pressed on two sides of the pin shaft, the inner chain boards are pressed on the inner sides of the outer chain boards, the sleeve is arranged between the inner chain boards, and the roller which can rotate is arranged outside the sleeve. The low-maintenance chain is reasonable in design, simple in structure and convenient to use, facilitates lubrication and maintenance, and is long in service life.

Description

The low chain of safeguarding
Technical field
The utility model relates to technical field of transmission, has been specifically related to the low chain of safeguarding in the technical field of transmission.
Background technique
Existing chain generally is made up of bearing pin, sleeve and roller etc.Reaching between sleeve and the roller between bearing pin and the sleeve is Spielpassung, generally be lubricated when assembling, but service time one is long, is easy to generate mechanical wear between the two, influences chain and uses, or even damage chain.Chain in use is not easy to dismounting, and this moment, difficulty was bigger if need to lubricate again, if bearing pin is that the die bearing pin is then more not quick detachable.In order to remedy the defective of prior art, need a kind of novel chain of research and development to replace.
Summary of the invention
Technical problem to be solved in the utility model is to provide low and safeguards chain, and is reasonable in design, simple in structure, easy to use, makes things convenient for lubricating maintenance, long service life.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: the low chain of safeguarding, comprise outer plate, inner plate, sleeve, roller, bearing pin, described bearing pin both sides are pressed with outer plate, described outer plate inboard is pressed with inner plate, be provided with sleeve between the described inner plate, described sleeve is provided with rotating roller outward.
As preferably, an end of described bearing pin is provided with oil hole, and the outside of described oil hole is provided with pump nozzle.By adopting this set, can conveniently lubricant oil be injected in the bearing pin, thereby can be lubricated bearing pin at any time.
As preferably, the center of described bearing pin is provided with oil outlet.By adopting this set, the convenient lubricant oil that will be infused in bearing pin is diverted to each parts.
As preferably, described sleeve radially be provided with the sleeve oilhole.By adopting this set, can conveniently the lubricant oil in the bearing pin be lubricated sleeve.
As preferably, can rotate relatively between described roller and sleeve and sleeve and the bearing pin three.By adopting this set, use more flexibly, cooperate more tacit.
Beneficial effect:
The utility model adopts technique scheme to provide low and safeguards chain, has remedied the defective of prior art, has avoided the process of dismounting chain cleaning, and is reasonable in design, simple in structure, easy to use, makes things convenient for the lubricating maintenance of chain, prolonged the working life of chain.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is plan view of the present utility model.
Embodiment
Shown in Fig. 1-2, hang down and safeguard chain, comprise bearing pin 1, sleeve 2 and roller 3, described bearing pin 1 both sides are pressed with outer plate 4,4 liang of inboards of described outer plate are pressed with inner plate 5, are provided with sleeve 2 between the described inner plate 5, are provided with rotating roller 3 outside the described sleeve 2.One end of described bearing pin 1 is provided with oil hole 6, and the outside of described oil hole 6 is provided with pump nozzle 7.The center of described bearing pin 1 is provided with oil outlet 8.Described sleeve 2 radially be provided with sleeve oilhole 9.Can rotate relatively between described roller 3 and sleeve 2 and sleeve 2 and bearing pin 1 three.
During real work, lubricant oil is injected into oil hole 6 from pump nozzle 7, the center of bearing pin 1 is provided with oil outlet 8, sleeve 2 radially be provided with sleeve oilhole 9, the lubricant oil that is infused in the oil hole 6 fills up gap between bearing pin 1 and sleeve 2 and sleeve 2 and the roller 3 by oil outlet 8 and sleeve oilhole 9, do not need to dismantle chain thereby reach, can play the effect of lubricated chain again.Remedy the deficiencies in the prior art, avoided the trouble of dismounting chain, reasonable in design, simple in structure, easy to use, make things convenient for the lubricating maintenance of chain, prolonged the working life of chain.
Specific embodiment described herein only is that the utility model spirit is illustrated, the utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
