Description
Technical field
The utility model belongs to high-speed chain drive technology field, be specifically related to a kind of in-outer compound engagement Hy-Vo(rolls the pin formula) silent chain and the combination of the outer gearing Hy-Vo silent chain ordered arrangement new type power transmission usefulness Hy-Vo silent chain system of installing.
Background technique
The silent chain transmission be widely used in various requirement motion steadily, low, the fast workplace of noise, such as fields such as motor car engine, Coal Mechanical, oil-well rigs.Product and the specification of silent chain are various, and application is very extensive, and silent chain is divided into several forms such as interior engaging tooth shape chain, outer meshing silent chain, inside and outside compound engaging tooth shape chain by the difference of mesh mechanism usually.
The most common silent chain is the outer meshing silent chain of carrier bar outside straight flange flank profil and the engagement of sprocket wheel straight-side profile on the engineering at present, and the moment that is engaged on of each chain link of this silent chain and sprocket wheel finishes, and engagement process belongs to non-conjugated engagement.Because chaindriven polygon effect has larger impact shock and noise, has a strong impact on the performance of main frame.
In-outer compound engaging tooth shape chain is a kind of New Silent Chain, when engaging-in with drive sprocket in the silent chain transmission process, what the inside curve flank profil of evagination realized is the process that progressively is transitioned into outer gearing with the interior engagement of an one gear teeth, the so compatible advantage of inside and outside engaging tooth shape chain, the wearing and tearing that can alleviate silent chain chain sheet, bearing pin and sprocket teeth simultaneously.But in being for all chain links-and outer compound Hy-Vo chain, because the special-shaped bearing pin of non-circle is the numerical value accumulation of the pitches function that produces and chain internode to rolling, and cause work carrier bar and the sprocket teeth generation meshing interference of part chain link.
Publication number is that the Chinese patent of 202579849U has also related to and a kind ofly rolls pin formula silent chain transmission system, but the engagement system that it adopts is outer gearing, belongs to non-conjugated engagement.Because chaindriven polygon effect, have larger impact shock and noise to make main frame have many defectives, simultaneously because the carrier bar row that adopts morely causes that systematic part is many, quality large, the processing and assembling difficulty greatly, the more high problems of cost.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of new type power transmission Hy-Vo silent chain system with low noise, suitable high speed, heavy duty, speed change, variable load.
For solving the problems of the technologies described above the technological scheme that adopts be:
A kind of new type power transmission includes Hy-Vo silent chain 1, drive sprocket 2 and driven sprocket 3 with Hy-Vo silent chain system.
Described Hy-Vo silent chain 1 by interior-outer compound carrier bar 10, outer gearing carrier bar 11, have strong market potential 12, short pin 13 and guide card 14 form, in-outer compound carrier bar 10 couples together by the 12 and short pins 13 of having strong market potential with adjacent outer gearing carrier bar 11, guide card 14 is had strong market potential by the difference that connects two chain plate holes and 12 is connected, and forms the Hy-Vo silent chain 1 that seals by many groups carrier bar and bearing pin, bearing pin with guide card.
Described guide card 14 12 contacts by interference fit with having strong market potential, and prevents bearing pin at axial play, guarantees that chain drive system normally moves.
In described-and outer compound carrier bar 10 has outer teeth profile 100 and interior flank profil 101, and described outer gearing carrier bar 11 has outer teeth profile 110 and interior flank profil 111; When interior-outer compound carrier bar 10 is engaging-in with drive sprocket 2 in transmission process, the interior flank profil 101 of evagination at first with tooth contact, engagement in realizing, further engaging-in along with these gear teeth, because relatively rotating between the adjacent link, outer teeth profile 100 and the tooth contact of the work carrier bar of adjacent link are realized outer gearing.In engagement process, outer gearing carrier bar 11 contacts with drive sprocket 2 with its outer teeth profile 110, realizes engagement, along with relatively rotating of carrier bar, realize the location with its outer teeth profile 111, interior-outer compound carrier bar 10 is consistent with the positioning states of outer gearing carrier bar 11 on sprocket teeth.
The beneficial effects of the utility model are:
(1) adopts outer gearing and interior-Hy-Vo silent chain that outer compound engagement combines, have the pitches function of Hy-Vo chain, can reduce the polygon effect in the chain transmission process, reduce vibration and impact, be applicable at a high speed, heavy duty, the large operating mode of centre distance;
(2) have again outer gearing, interior-two kinds of mesh mechanisms of outer compound engagement concurrently simultaneously, can satisfy by optimizing and revising its ordered arrangement rule the individual demand of different main frames;
(3) because the multiple-effect of pitches, interior-outer compound mesh mechanism and " interior-outer compound engagement+outer gearing mechanism ", can satisfy the individual demand for the centre of sprocket distance, having realized the ekaconjugation transmission of this novel Hy-Vo silent chain, is a kind of high efficiency, low noise, strong wear-resisting Novel transmission system.
