Abstract

The utility model discloses a chain that wear resistance is high, including a plurality of sleeves, inner plate, round pin axle and outer chain plate, the sleeve interpolation is equipped with the round pin axle, connects through the inner plate between the sleeve, a round pin axle both ends cover is equipped with outer chain plate, and two one sides that outer chain plate is relative are provided with the concave station, telescopic both ends extend to in the concave station, the sleeve overcoat is equipped with the roller, outer chain plate's the outside is provided with the boss, the utility model discloses simple structure, reasonable in design through the length that improves the salient inner plate of sleeve, makes the friction area that assembles the back sleeve and sell the axle show and improves, set up the concave station through the inboard at outer chain plate, make in the sleeve tip embolias it, can guarantee that lubricating grease is not thrown out at high -speed in operation, need not refuel maintenances in the use, simultaneously the dust also extremely the difficulty advance destroy the grease in the gap, because outer chain plate free accommodation sleeve tip for during outer chain plate also added the function of wear -resistanting, whole friction area increased, and life improves 2 times, saves a large amount of steel, reduced and scrapped the pollution of chain to the environment.

Description

The chain that a kind of wear-resisting property is high

Technical field

The utility model relates to drive chain field, the chain that specifically a kind of wear-resisting property is high.

Background technique

Traditional bushed chain and roller chain generally comprise sleeve, bearing pin, inner plate and outer plate, and roller chain also has roller, as shown in Figure 1-2, ordinary circumstance lower bearing pin overcoat is provided with sleeve, be connected by inner plate between sleeve with sleeve, sleeve two ends, bearing pin two ends arranged outside outer plate; Due to its structures shape, it has a following significant shortcoming: 1. lubricant grease is very easily subject to the pollution of rainwater and dust, especially the exposed use occasion outside of chain, the drive chain that such as motorcycle chain or service condition are severe, goes bad very soon and loses lubricating and antirust performance; Grease is got rid of from the gap of interior outer plate in high speed operation in addition, chain loses greasy property, later stage uses needs regular lubricating oil filling, and the machine oil of mobility can only be added, the bad lubricant oil of mobility adds and does not have lubrication less than in chain gap, and the oil of mobility is doomed to be got rid of away soon in running up, through motorcycle chain proving ground test, do not have the condition lower driving chain life-span of lubricant oil to be travel 6000-8000 kilometer, and the chain distance travelled of part manufacture same under good lubrication condition is more than 12000 kilometers; 2. friction pair are single, and the parts that bushed chain and roller chain wearing and tearing finally affect chain length are all sleeve and bearing pin, and friction contact area is very little, and sleeve and bearing pin wearing and tearing rear chain total length increase, so working life is limited; For these reasons, need to carry out performance optimization to meet user demand to the chain of prior art.

Model utility content

The purpose of this utility model is that providing a kind of designs ingenious, that long service life, Maintenance free, wear-resisting property are high chain, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technological scheme:

The chain that a kind of wear-resisting property is high, comprise multiple sleeve, inner plate, bearing pin and outer plate, bearing pin is inserted with in described sleeve, connected by inner plate between sleeve, described bearing pin two ends are arranged with outer plate, the side that two outer plates are relative is provided with concave station, and the two ends of described sleeve extend in concave station.

As further program of the utility model: described bush outer sleeve is provided with roller.

As the utility model further scheme: the arranged outside of described outer plate has boss.

As the utility model further scheme: described bush outer sleeve is provided with roller and the arranged outside of outer plate has boss.

Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, and protrude the length of inner plate by improving sleeve, after making assembling, the friction area of sleeve and bearing pin significantly improves; Concave station is set by the inner side at outer plate, makes sleeve ends be inserted in it, can ensure that lubricant grease is not thrown out of in running up, do not need in using to refuel and safeguard, simultaneously dust also extremely difficulty enter in gap and destroy grease; Because outer plate encases sleeve ends, make outer plate also add in the function of wear-resistant elongation, overall friction area increases, and improves 2 times working life, saves great deal of steel, reduces and scraps the pollution of chain to environment.

Embodiment

Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.

Embodiment 1

Refer to Fig. 3, the bushed chain that a kind of wear-resisting property is high, comprise multiple sleeve 1, inner plate 2, bearing pin 3 and outer plate 4, bearing pin 3 is inserted with in described sleeve 1, connected by inner plate 2 between sleeve 1, described bearing pin 3 two ends are arranged with outer plate 4, and the side that two outer plates 4 are relative is provided with concave station 6, and the two ends of described sleeve 1 extend in concave station 6.

Embodiment 2

Refer to Fig. 4, the bushed chain that a kind of wear-resisting property is high, comprise multiple sleeve 1, inner plate 2, bearing pin 3 and outer plate 4, bearing pin 3 is inserted with in described sleeve 1, connected by inner plate 2 between sleeve 1, described bearing pin 3 two ends are arranged with outer plate 4, and the side that two outer plates 4 are relative is provided with concave station 6, and the opposing side of two outer plates 4 is provided with boss 7; The two ends of described sleeve 1 extend in concave station 6.

Embodiment 3

Refer to Fig. 5, the roller chain that a kind of wear-resisting property is high, comprise multiple sleeve 1, roller 5, inner plate 2, bearing pin 3 and outer plate 4, roller 5 is arranged with outside described sleeve 1, be inserted with bearing pin 3 in sleeve 1, connected between sleeve 1 by inner plate 2, described bearing pin 3 two ends are arranged with outer plate 4, the side that two outer plates 4 are relative is provided with concave station 6, and the two ends of described sleeve 1 extend in concave station 6.
