Abstract
The utility model relates to a tooth form chain with high connecting firmness, specifically to the tooth form chain in a transmission apparatus. The tooth form chain is formed by connecting adjacent and spaced chain plates with hinge pins or hinge joint elements and employs a type of n*(n+1), wherein the n is not less than 2. In a chain unit with n+1 chain plates, the chain plates on two ends are in interference fit with the hinge pins; the other chain plates are in clearance fit with the hinge pins; two ends of each hinge pin are provided with four-corner pressure rivets; and joints of the chain unit are locked by steel wire locking pins. The tooth form chain has improved connection firmness, fit precision and assembly quality, has improved lateral impact resistance and prolonged service lifetime, and thus has stable transmission performance, thereby meeting the requirements for high speed, heavy load, variable speed, variable load and high kinematic accuracy.
Description
Technical field
The utility model relates to the silent chain in a kind of transmission device, relates in particular to be used for the high silent chain that connects the transmission device of fastness, steady, the anti-side knock ability of transmission performance and high assembly quality of requirement.
Background technique
Silent chain is to use a kind of very widely type of belt drive in the mechanical industry, is specially adapted under the operating mode that high-speed overload, speed change variable load and kinematic accuracy have relatively high expectations.In recent years, along with the continuous development of high speed chain-driven technology, novel automobile, motorcycle engine have been used silent chain more and more widely.But; Silent chain joint jump ring comes off, the packing ring on the bearing pin comes off and cotter pin is cut off and chain is broken off can't proper functioning; This is the problem that raising chain link connection fastness and assembly quality need solve always; Especially at a high speed, heavy duty and having under the situation of side knock, this problem is more outstanding.Connecting fastness is to guarantee that chain in use keeps the important indicator of chain link framework integrity.If it is not enough that chain link connects fastness, gently then be that shift at chain wear of hinge position, chain produces sharply wearing and tearing elongation; Heavy then can cause the chain disintegration of falling apart, can't keep proper functioning.
Summary of the invention
The utility model provides a kind of silent chain of high connection fastness, problems such as the ubiquitous connection fastness of silent chain is low to solve, the ability of anti-side knock and assembly quality disappearance.
The technological scheme that the utility model is taked is: connect to form by adjacent alternate carrier bar assembling and with bearing pin or hinged member; Be the type of n * (n+1), wherein n >=2 are on the chain link of n+1 at the carrier bar number; Two ends carrier bar and bearing pin interference fit; All the other carrier bars and bearing pin are Spielpassung, and the two ends of said bearing pin are respectively four jiaos and press, and the link joint place adopts solid long cotter to end lock.
A kind of mode of execution of the utility model: silent chain can for engaging tooth shape chain in the round pin formula, outer gearing silent chain, inside and outside compound engaging tooth shape chain and in order spread pattern and roll engaging tooth shape chain in the pin formula, outer gearing silent chain, inside and outside compound engaging tooth shape chain and spread pattern in order thereof.
A kind of mode of execution of the utility model is: the solid long cotter material is 60Si
2The Mn spring steel.
A kind of mode of execution of the utility model is: silent chain is on the chain link of n+1 if adopt outer conduction at the carrier bar number, two ends guide plate and bearing pin interference fit.
A kind of mode of execution of the utility model is: the link joint place can adopt that the axial elasticity back-up ring ends lock, the enclosed type jump ring ends lock or type semienclosed jump ring ends lock.
A kind of mode of execution of the utility model is: carrier bar can adopt wide waist type and narrow waist type.
Traditional silent chain mostly adopts carrier bar and bearing pin Spielpassung, in the outside, carrier bar two ends, a packing ring is arranged respectively; With the bearing pin interference fit, two limit rivetings are all adopted at the two ends of bearing pin, and the link joint place adopts cotter pin or jump ring to end lock; Its shortcoming is to connect the fastness deficiency, and assembly quality is not high and the die easy abrasion is arranged under the side knock situation; Packing ring slippage, jump ring come off or cotter pin is cut off, thereby make the chain can't proper functioning.And the utility model has bigger riveted amount for guaranteeing silent chain when assembling; The two ends of adopting bearing pin respectively four jiaos press; Carrier bar and bearing pin interference fit are adopted in the chain link two ends; Thereby improved the die quality and the quality of fit of silent chain, increased the working life of silent chain, satisfied the requirement of connection fastness.
The link joint place adopts solid long cotter to end lock, and material is 60Si
2Spring steel such as Mn, the two ends tempering heat treatment reduces its hardness, makes it crooked easily.Because 60Si
2Spring steel such as Mn have good elasticity, when bearing heavy load, do not cause plastic deformation; High fatigue strength is arranged, under load acts on repeatedly, have long working life; And enough toughness and plasticity are arranged, can prevent has the unexpected brittle failure of solid long cotter under the lateral impact forces effect at chain link.
The advantage of the utility model is: under the prerequisite that does not change silent chain bulk and bearing capacity; Connection fastness, quality of fit and the assembly quality of silent chain have been improved; The ability and the working life of the anti-side knock of silent chain have been strengthened; Make its transmission performance steady, satisfy novel automobile, motorcycle engine high-speed overload, speed change variable load and the high requirement of kinematic accuracy.
