Abstract
The utility model discloses a high-strength chain, wherein two inner chain plates and two sleeves are fixedly connected in interference fit; rollers capable of rotating are sleeved on the sleeves, thereby forming a chain link; the chain links are connected through two outer chain plates and a pin shaft; the pin shaft penetrates through the sleeves and two ends of the pin shaft runs through the outer chain plates and then are fixedly connected through square rivet heads; both the inner chain plates and the outer chain plates are right-edge alloy structure steel chain plates; pin holes in the inner chain plates and the outer chain plates are subjected to ball sizing by adopting a steel ball, and the rollers are steel rollers with a medium carbon alloy structure. The technical scheme is convenient in use, and can be exchanged with the same specification of standard chains. The chain has larger extreme tensile load/work load, longer service life and better reliability compared with the standard chains.
Description
Technical field
The utility model relates to the transmission chain bar, relates in particular to a kind of heavy-load type high-test chain.
Background technique
At present, the limited occasion in some heavy duties and space also is to use common standard chain, in use because of chain safety coefficient not high (ultimate elongation load/work loads); Often fracture; Necessary frequent change chain, working life is low, poor reliability; Cost is high concerning the end user, and inconvenient.
Summary of the invention
In order to solve above-mentioned technical problem; The purpose of the utility model provides a kind of high-test chain, the interchangeable use of easy to use and standard chain same specification; This chain has bigger ultimate elongation load/work loads, chain long service life, good reliability with respect to standard chain.
In order to reach above-mentioned purpose, the technological scheme below the utility model has adopted:
A kind of high-test chain; Two inner plates are fixedly connected with two sleeve interference fit; The sheathed roller that can rotate on the sleeve; Form a chain link like this, be connected with bearing pin through two outer plates between the chain link, bearing pin is arranged in the sleeve and outer plate is run through again through cubic die fixed connection in two ends; Wherein, said inner plate and outer plate are the Alloy Constructional Steel carrier bar of straight flange type, and the pin-and-hole on said inner plate and the outer plate all adopts ball sizing to handle, and said roller is the medium carbon structural alloy steel roller.
The utility model is owing to adopted above technological scheme, and part material is all selected high-quality alloy steel for use, the corresponding adjustment of design of part; Carrier bar is adjusted into board-type from 8 fonts, can strengthen pin diameter, and parts machining process has also had great improvement; Carrier bar increases ball sizing, produces pressure stress at bore edges, improves the fatigue strength of carrier bar when improving carrier bar aperture bright band; Roller adopts medium carbon structural alloy steel, not only can guarantee certain intensity but also certain toughness can be arranged after the heat treatment.Improved the ultimate elongation load of chain like this, safety coefficient is high, good reliability, thus prolonged working life of chain.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done a detailed explanation.
Embodiment 1:
Like Fig. 1, a kind of high-test chain shown in Figure 2; Two inner plates 1 are fixedly connected with two sleeve 4 interference fit; The sheathed roller that can rotate 5 on the sleeve 4; Form a chain link like this, be connected with bearing pin 3 through two outer plates 2 between the chain link, bearing pin 3 is arranged in the sleeve 4 and outer plate 2 is run through again through cubic die fixed connection in two ends; Wherein, said inner plate 1 and outer plate 2 are the Alloy Constructional Steel carrier bar of straight flange type, and the pin-and-hole on said inner plate 1 and the outer plate 2 all adopts ball sizing to handle, and said roller 5 is the medium carbon structural alloy steel roller.Like this, chain link and bearing pin can rotate each other.The mutual successively chain that just can obtain any joint number that connects of chain link and chain link.Bearing pin runs through behind the outer plate with the technology of cubic die, makes the bearing pin external diameter increase, thereby increases the fastness of bearing pin and carrier bar.
Because of chain uses in the limited occasion in heavy duty and space; To changing on chain part structure and the technology; Carrier bar is selected high-quality alloy steel for use, uses straight flange type structure instead, after heat treatment also requires to use ball sizing; Make bore edges produce pressure stress, more than improve the fatigue strength that improves carrier bar when having improved carrier bar aperture bright band; Roller adopts medium carbon structural alloy steel, repeatedly after the heat treatment process checking, can reach certain toughness when adopting whole heat treatment process to satisfy intensity.Chain is carrying out strong prestretching on special device after the assembling, improve the whole fatigue strength of chain.Above-mentioned improvement makes chain, and in use safety coefficient is high, and good reliability has finally prolonged working life of chain.
