Abstract

The utility model relates to a limiting device for an open-loop chain idler wheel, which comprises a pin shaft of an open-loop chain, wherein liner bushings are respectively arranged at two end parts of the pin shaft; the liner bushings, as well as inner edges of steel idler wheels and outer edges of rubber idler wheels for limiting are assembled to form an integral idler wheel from inside to outside; and the outer ends of the liner bushings are fixed by retainer rings. For the limiting device adopting the technical scheme, the outer edges of rubber idler wheels are adopted so that the resistance suffered by a chain can be reduced in the moving process, and the impact is reduced; the limiting device has the advantages of simpleness, reliability and rapidness in maintenance, the fitness capability of the chain is increased and the design difficulty of a guide rail of the chain is solved.

Description

A kind of open loop chain roller limit stoper

Technical field

The utility model relates to a kind of open loop chain roller limit method, specifically a kind of open loop chain roller design mode.

Background technique

Modern naval vessels are for the continuity that satisfies combat duty and improve fighting efficiency better, and ammunition in time additional has very big influence.For the chain design of sealing, exist and take up room greatly, raised position is limited bigger, and speed is very fast relatively, and the spacing design of chain roller is simpler.The project organization of open loop chain takes up room less, is satisfying under the situation of mending the bullet requirement, and the raised position design is more convenient, and the spacing design of chain roller is accurate complicated.

Summary of the invention

At the requirement that ammunition in hand replenishes, in making hoisting cage ammunition can directly being imported launcher on the warship vizard plate from storage when one-time pad, the utility model provides the limit stoper of a kind of ammunition chain roller when the holder of open loop chain bullet raises up.

For addressing the above problem, the utility model by the following technical solutions:

The utility model comprises the bearing pin of open loop chain, in two ends of bearing pin lining is set respectively, described lining with bear the steel roller inner edge of position-limiting action, the roller that the rubber roll outer rim is assembled into integral type from inside to outside; And described lining outer end is fixed with back-up ring.

Described rubber roll outer rim is a urethane rubber roller outer rim.

Between two rollers, near each roller one side outer plate is set, outer plate is assemblied on the bearing pin, and sleeve is installed on the bearing pin, and inner plate is installed on the sleeve, and inner plate combines the bearing pin that forms whole and adjacent the opposing party and links together with the end of sleeve.

Adopt the utility model of technique scheme, adopted the rubber roll outer rim, make chain can alleviate resistance at the volley, reduce to impact, have simple, reliable, safeguard advantage efficiently, improved the suitable dress ability of chain, solved the chain guide design difficulty.

Fig. 1 is overall structure figure of the present utility model.

Fig. 2 is open loop chain Placement figure.

Embodiment

As shown in Figure 1, the utility model comprises the bearing pin 7 of open loop chain, is equipped with sleeve 8 on the bearing pin 7.Two ends at bearing pin 7 are provided with lining 3 respectively, and 7 of lining 3 and bearing pins rotatablely move each other, and lining 3 outer ends utilize back-up ring 9 to limit the traversing of lining 3.

Above-mentioned lining 3 with bear the steel roller inner edge 1 of position-limiting action, the roller that rubber roll outer rim 2 is assembled into integral type from inside to outside, wherein, roller outer rim 2 is a urethane rubber roller outer rim, spacing in the inside groove of guide rail 10 rolling motion.

Between two rollers, outer plate 4 is set near each roller one side, outer plate 4 is assemblied on the bearing pin 7, the other end and adjacent bearing pin link together, relative between rotate.Inner plate 5 is installed on the sleeve 8, and inner plate 5 combines the bearing pin that forms whole and adjacent the opposing party and links together with the end of sleeve 8; At the outside of sleeve 8 suit roller 6, roller and sprocket tooth engagement, transferring power; At the aforesaid part of bearing pin another side, form a complete chain.
