Abstract
The utility model discloses a marine diesel engine chain. The marine diesel engine chain comprises outer links and inner links, wherein the outer links and the inner links are all 8-shaped and connected together in a penetrating manner by pin shafts, a bushing is arranged between the inner links and the pin shafts, a roller is sleeved to the outer surface of the bushing, the inner links and the outer links are arranged in a mutually staggered manner, and fixing sleeves are arranged on the end parts of the pin shafts and sleeved on the outer surfaces of the outer links; and the pin shafts on the end part of the marine diesel engine chain are connected with connection links, and connection pin shafts are connected to the outer ends of the connection links in a penetrating manner. The chain has characteristics of being high in strength, high in stability, ultralong in service life, and the like, as well as is suitable for a timing transmission system for a diesel engine chain.
Description
Technical field
The utility model relates to a kind of chain, is specially a kind of marine diesel engine chain.
Background technique
Chain is connected and composed successively by chain link conventionally, each chain link connects and composes by outer plate, inner plate, bearing pin, roller, sleeve, outer plate and inner plate are equipped with through hole and link together by bearing pin, at bearing pin, sleeve are installed outward, be provided with roller and realize transmitting function between inner plate.But under heavy load operating conditions, there is the problem of intensity difference, affect the stability of marine diesel engine work.
Model utility content
The technical problem that the utility model solves is to provide a kind of marine diesel engine chain, the problem proposing to solve background technique.
The technical problem that the utility model solves realizes by the following technical solutions:
Marine diesel engine chain, comprise outer link, inner link, outer link, inner link are " 8 " font and pass through bearing pin cross-under together, between inner link and bearing pin, be provided with sleeve, the outer surface of sleeve is socketed with roller, inner link and outer link are interwoven, and the end of bearing pin is provided with fixed cover, and fixed cover is located at the outer surface of outer link; The bearing pin of marine diesel engine link ends is connected with connecting link, and the outer end cross-under of connecting link has connection bearing pin.
Described outer link, inner link are forging spring steel carrier bar; Bearing pin is modified carbonitriding part; Sleeve and roller are the modified carbonitriding part of round steel.
Compared with prior art, the beneficial effects of the utility model are: this chain has the features such as high strength, high stability and long service life, is applicable to diesel engine chain timing driving system.
Accompanying drawing explanation
Fig. 1 is the plan view of marine diesel engine chain.
Fig. 2 is the plan view of marine diesel engine chain.
Embodiment
In order to make of the present utility modelly to realize technological means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 and Figure 2, marine diesel engine chain, comprise outer link 2, inner link 1, outer link, inner link are " 8 " font and pass through bearing pin 3 cross-under together, between inner link and bearing pin, be provided with sleeve 4, the outer surface of sleeve is socketed with roller 5, and inner link and outer link are interwoven, the end of bearing pin is provided with fixed cover 8, and fixed cover is located at the outer surface of outer link; The bearing pin of marine diesel engine link ends is connected with connecting link 6, and the outer end cross-under of connecting link has the bearing pin 7 of connection.
This chain and chain-plate adopts the forging of extraordinary high-quality spring steel, and carrier bar material structure is good, and after the heat treatment of carrier bar multipurpose stove, fine finishing pitch hole, has eliminated the pitch causing because of heat treatment deformation inconsistent; The modified rear cold working of bearing pin, adopts carbonitriding heat treatment process; Sleeve, the modified rear carbonitriding of round steel for roller; Sleeve refines sleeve endoporus after being pressed into carrier bar, has guaranteed that guide clearance height is consistent.This product is a kind of chain transmission timing system for diesel engine, comprises the important component part of camshaft chain transmission timing system and high pressure oil pump chain transmission timing system.This chain has the features such as high strength, high stability and long service life, is applicable to diesel engine chain timing driving system.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
