Abstract
The utility model relates to a lateral bending chain, in particular to a lateral bending chain used for transmission lines for electronic products. The lateral bending chain comprises a chain link, both ends of the chain link are provided with outer plates, the inner lateral walls of the outer plates are provided with inner plates, a pin shaft is inserted between each outer plate and each inner plate, and is externally connected with a sleeve barrel, a roller is arranged between the two inner plates, and is interlinked with the sleeve barrel. The lateral bending chain is characterized in that the sleeve barrel is shaped like a horn. The lateral bending chain increases contact area, effectively controls precision of chain length, and greatly extends service life of the chain.
Description
Technical field
The utility model patent relates to a kind of lateral bending chain, relates in particular to be used for a kind of lateral bending chain of using on the electronic product conveyor line of being used for.
Background technique
Owing to produce the particularity of electronic product workshop structure, be conserve space, often design the turning track of some different radiis, conventional standard chain can only be carried by straight line, can't satisfy the requirement of turning track, therefore require used chain that certain radius of side-bow is arranged, this has just developed side bow roller chain, this chain has certain radius of side-bow R, big I is according to different orbit radius designs, conventional side bow roller chain design principle is to strengthen the gap of sleeve and bearing pin and the gap of strengthening interior outer link, general pin diameter and the lengthening bearing pin length of reducing, chain reaches the purpose of lateral bending by the hollow pin gap when turning when operation like this, this simple in structure, easily manufactured.But when chain used, because bearing pin and sleeve are to contact, area of contact was little, and chain mill an ancient egg-shaped, holed wind instrument is fast, and chain elongates easily, had reduced chain working life.
Chinese patent CN101417737, a kind of lateral bending chain is disclosed, this kind lateral bending chain is in the running that moves ahead, can realize to a lateral bending song, satisfy needs in some chain-driven and do suitably crooked specific demand to a side, the lateral bending chain structure, comprise whole chain link body, chain drive axle, chain lateral bending axle and rolling bearing, on the whole chain link body chain lateral bending axle axis hole and chain drive axle axis hole are arranged, and chain lateral bending axle axis hole and chain drive axle axis hole are 90 ° of crossings on different level on whole chain link body; On the chain drive axle and on the chain lateral bending axle rolling bearing is being housed all, is realizing replacing sliding friction, can reduce surface friction drag greatly, reducing power consumption, and can obviously reduce operational noise with rolling friction.This patent of invention complex structure, using effect is not good.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provides a kind of at trumpet-shaped sleeve, is contacted with the point of sleeve by bearing pin and makes the face contact into, has increased the lateral bending chain of area of contact.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of lateral bending chain that has horn-like sleeve, comprise chain link, the two ends of chain link are respectively equipped with outer plate, the madial wall of outer plate is respectively equipped with inner plate, be plugged with bearing pin between described outer plate and inner plate, bearing pin is socketed with sleeve outward, is provided with roller between inner plate, described roller sleeve is connected on the sleeve, it is characterized in that: described sleeve is horn-like.Sleeve and bearing pin also become the face contact by contacting like this, have increased area of contact, have controlled the chain length precision equally effectively, have improved chain working life greatly.
As preferably, described sleeve laterally in cross line two ends be respectively horn-like.
Therefore, a kind of lateral bending chain that has horn-like sleeve of the present utility model has increased area of contact, has controlled the chain length precision effectively, has improved chain working life greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, a kind of lateral bending chain that has horn-like sleeve, comprise chain link, the two ends of chain link are respectively equipped with outer plate 1, and the madial wall of outer plate 1 is respectively equipped with inner plate 2, and 2 of outer plate 1 and inner plates are plugged with bearing pin 3, the bearing pin 3 outer sleeves 4 that are socketed with, 2 of inner plates are provided with roller 5, and roller 5 is socketed on the sleeve 4, and the laterally middle two ends of crossing line of sleeve 4 are respectively horn-like.
Claims (2)
1. lateral bending chain that has horn-like sleeve, comprise chain link, the two ends of chain link are respectively equipped with outer plate (1), the madial wall of outer plate (1) is respectively equipped with inner plate (2), be plugged with bearing pin (3) between described outer plate (1) and inner plate (2), bearing pin (3) is outer to be socketed with sleeve (4), is provided with roller (5) between inner plate (2), described roller (5) is socketed on the sleeve (4), it is characterized in that: described sleeve (4) is for horn-like.
2. a kind of lateral bending chain that has horn-like sleeve according to claim 1 is characterized in that: the laterally middle two ends of crossing line of described sleeve (4) are respectively horn-like.
