Abstract
This utility model relates to a chain, in particular to a central conveyer chain for large-scale mine mechanics, steel and metallurgy industries which require large conveyance capacity and excellent stability, which discloses a energy-saving central chain conveyer chain with precise forging and high efficiency, which comprises an interior chain plate (3), an exterior chain plate (2), a pin shaft (4) and a sleeve (1), wherein the interior chain plate (3) and the exterior chain plate (2) are provided with pin holes, and the pin holes of the exterior chain plate (2) are blind holes (91). Both terminals of the pin shaft (4) clearance fit the blind holes (91) of the two exterior chain plates, the intermediate portion of the pin shaft (4) clearance fits the sleeve (1) which interference fits the pin holes (7) of the interior chain plate (3), and rotation spacing mechanisms (5, 6) are equipped between the interior chain plate (3) and the exterior chain plate (2). Thereby, this utility model has the advantages of adequate wearing of the pin shafts loading surfaces of the chains, adequate weariness, and prolonged service life, and the detaching between the chain links needs no special tools.
Description
Technical field
The utility model relates to a kind of chain, relates in particular to a kind of large-scale mine machinery, iron and steel, metallurgy industry operational throughput of being used for and requires bigger central conveyer chain greatly and steadily.
Background technology
Closed-tolerance forging central authorities conveyer chain is mainly used on large-scale mine machinery, iron and steel, the metallurgical load transfer device, and it cooperates with central transportation sprocket and has the big advantage of operational throughput.But the chain link of currently used conveyer chain comprises interior pin link plate, bearing pin, cylinder and sleeve, wherein bearing pin and pin link plate interference fit, bearing pin can not freely rotate by the pin-and-hole on pin link plate, between bearing pin and the cylinder to contact loaded area limited, the a part of cylinder that is bearing pin contacts carrying with cylinder, and other most of cylinder does not contact carrying with cylinder, and the cylinder of so frequent contact is tired easily, and the life-span is shorter; Simultaneously, because interference fit between bearing pin and the pin link plate, the dismounting between the chain link needs special tool.
Summary of the invention
Dismounting between local contact fatigue wearing and tearing of the bearing pin that has overcome chain of the prior art of the present utility model and the chain link needs the defective of special tool, closed-tolerance forging high-efficiency and energy-saving type central authorities chain conveyer chain is provided, bearing pin is fatigue wear evenly, prolong the chain life-span, simultaneously, the dismounting between the chain link does not need special tool.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: closed-tolerance forging high-efficiency and energy-saving type central authorities chain conveyer chain, comprise inner plate, pin link plate, bearing pin and sleeve, inner plate and pin link plate are equipped with pin-and-hole, the pin-and-hole of described pin link plate is a blind hole, the blind hole free-running fit of the two ends of bearing pin and two pin link plates, the middle part of bearing pin and sleeve free-running fit, the pin-and-hole interference fit of sleeve and inner plate is provided with rotating limit device between inner plate and the pin link plate.
Described rotating limit device is that the two ends of arbitrary block of carrier bar in inner plate and the pin link plate are provided with the flange that " tongue " shape protrudes, and the side of an other carrier bar is provided with position-limited trough, and described flange can extend in the position-limited trough.
Described pin link plate comprises carrier bar and end cover, and carrier bar is provided with pin-and-hole, and end puts and is provided with blind hole, described end cover and pin-and-hole interference fit.
The centre of described pin link plate and inner plate is extended with the friction table top.
Therefore, the utlity model has the pin bearing section uniform wear of chain, evenly tired, life-saving, the dismounting between the chain link does not simultaneously need the advantage of special tool.

The specific embodiment
Below by embodiment, and, the technical solution of the utility model is described in further detail in conjunction with the accompanying drawings 2 to accompanying drawing 6.
The pin link plate 2 of present embodiment comprises carrier bar and end cover 9, and carrier bar is provided with pin-and-hole 7, and end cover 9 is provided with blind hole 91, end cover 9 and pin-and-hole 7 interference fit.
During installation pin link plate 2 at first with 3 one-tenth 90 ° of inner plates, the back pin link plate 2 of packing into forwards to parallelly with inner plate 3, flange 5 can extend in the position-limited trough 6 like this, pin link plate 2 just can not skid off, dismantling does not need special tool.Simultaneously bearing pin 4 can 360 ° in sleeve 1 and end cover 9 freely rotates, thus bearing pin 4 wearing face degree of utilizations 100%.
Simultaneously, this conveyer chain is to match with specific drive wheel, the centre of pin link plate 2 and inner plate 3 is extended with friction table top 33, this friction table top 33 contacts with the cylinder of sprocket wheel jointly with the middle part of carrier bar, and the friction table top 33 of extension is exactly in order to enlarge the wipe contact area of carrier bar and sprocket wheel cylinder.
