Abstract
The utility model provides a long-pitch transmission chain, at least comprising an inner chain node and an outer chain node which are connected in series in turn, wherein the inner chain node comprises two inner chain plates and a sleeve mounted between two inner chain plates, a roller is sleeved on the sleeve, the outer chain node comprises two outer chain plates and a pin axle, the pin axle is mounted between two outer chain plates by pin axle holes on the two outer chain plates, one end of the pin axle is provided with an axle head, another end of the pin axle is provided with a screw and a nut matched with the screw. Because one end of the pin axle is provided with the axle head, another end of the pin axle is provided with the screw and the nut, the outer chain plate is prevented from expanding outwards and the whole firmness of the chain is reinforced. An open pin is arranged on the pin axle to prevent the nut from rotating outwards, furthermore the firmness of the chain is ensured. Thus the working stability of the chain is good and the service life of the chain is long.
Description
Technical field
The utility model relates to a kind of meropodium apart from conveyer chain, belongs to mechanical transmission fields.
Background technology
Existing meropodium is widely used on the conveyer than the meropodium distance apart from conveyer chain, and mixes various annexes and become specification general conveyer chain various in style, like compress, bucket elevator etc.Existing meropodium adopts riveted way and pin link plate to fix apart from its bearing pin of conveyer chain.In use, often take place to get loose between bearing pin and the pin link plate, even the accident of pin link plate and chain disengaging, not only had a strong impact on its working stability, and service life is short.
Summary of the invention
The utility model provides a kind of meropodium apart from conveyer chain, has solved original meropodium apart from shortcomings such as conveyer chain poor work stability, service life are short.
Realize that the technical scheme that the utility model above-mentioned purpose is adopted is:
A kind of meropodium is apart from conveyer chain; At least comprise the inner link and the outer link of serial connection successively, inner link comprises two inner plates and is installed on the sleeve between two inner plates, is with roller on the sleeve; Outer link comprises two pin link plates and bearing pin; Bearing pin is installed between two pin link plates through the pin shaft hole on two pin link plates, and an end of bearing pin is a spindle nose, the other end of bearing pin be provided with screw thread and with the supporting nut of screw thread.
The end that bearing pin is provided with screw thread also is provided with packing ring and spring cotter, and packing ring is between nut and pin link plate, and spring cotter is positioned at the outside of nut; Be positioned on inner plate and the pin link plate of the same side with the screw thread of bearing pin on the chain otic placode all is installed, otic placode is the flat board that has mounting hole, is fixed in the outside of inner plate or pin link plate.
Because an end of bearing pin is a spindle nose, the other end of bearing pin is provided with screw thread and nut to this meropodium, can prevent that pin link plate from expanding outwardly, and has strengthened chain single-piece fastness apart from conveyer chain.The spring cotter that bearing pin is provided with can prevent the outside turn of nut, has further guaranteed the fastness of chain.Therefore the working stability of this chain is good, long service life.
Description of drawings
The meropodium that Fig. 1 provides for the utility model is apart from the structural representation of conveyer chain;
Fig. 2 is the structural representation of bearing pin;
Among the figure, 1-inner plate, 2-pin link plate, 3-bearing pin, 4-nut, 5-packing ring, 6-spring cotter, 7-otic placode, 8-roller, 9-sleeve.
The specific embodiment
The utility model is done bright in detail specifically below in conjunction with accompanying drawing.
The meropodium that the utility model provides is as shown in Figure 1 apart from the structure of conveyer chain; Inner link and outer link by being connected in series are successively formed, and inner link comprises two inner plates 1 and is installed on the sleeve 9 between two inner plates 1, is with roller 8 on the sleeve 9; Outer link comprises two pin link plates 2 and bearing pin 3; Bearing pin 3 is installed between two pin link plates through the pin shaft hole on two pin link plates 2, and the sleeve 9 of inner link is enclosed within on the bearing pin 3 of outer link in adjacent inner link and the outer link, composes in series whole chain successively.The structure of bearing pin 3 is as shown in Figure 2, and an end of bearing pin is a spindle nose, the other end be provided with screw thread and with the supporting nut 4 of screw thread.Be provided with packing ring 5 between nut 4 and the pin link plate 2, also be provided with spring cotter 6 on the bearing pin 3, spring cotter 6 passes the outside that bearing pin 3 is positioned at nut 4, stops nut 4 outside turns.
The spindle nose of all bearing pins 3 all is positioned at the same side of chain on the chain; On inner plate 1 on the other side of chain and the pin link plate 2 otic placode 7 is installed all; Otic placode 7 is for having the flat board of mounting hole; Be fixed in the outside of inner plate or pin link plate, otic placode and inner plate or pin link plate are substantial one in the present embodiment.
This meropodium can be formed multiple description apart from conveyer chain various annexes of fit on the mounting hole of otic placode, and uses very general widely conveyer chain, like compress, bucket elevator etc.
In use,,, prevent that it from expanding outwardly, improved the fastness of whole chain greatly, make the working stability of this chain good, long service life firm the holding onto of pin link plate because securing device has all been adopted at the two ends of bearing pin.
