Abstract
The invention discloses a pitch-varying two-sided internal and external composite-meshing silent chain transmission system which is mainly composed of a chain, a chain wheel A and a chain wheel B. One side of the chain is in meshed transmission with the chain wheel A, and the other side of the chain is in meshed transmission with the chain wheel B so that transmission of force and torque is achieved. The chain is mainly composed of a plurality of groups of working chain plates, short roll pins, long roll pins and guide pieces, wherein the short roll pins and the long roll pins penetrate through the chain plate holes of the working chain plates to enable the plurality of groups of working chain plates to be connected in a head-to-tail mode, and the guide pieces enable exposed portions located at two ends of two adjacent long roll pins to be fixed. The pitch-varying function of transmission of pitch-varying two-sided internal and external composite-meshing silent chains is achieved, the polygon effect, impact and vibration of the silent chain are remarkably reduced, the abrasion is reduced, and an S-shaped transmission function is achieved. Simultaneously, the pitch-varying two-sided internal and external composite-meshing silent chain transmission system has the advantages of meshing stability of an internal-meshing silent chain and positioning stability of an external-meshing silent chain.
Description
Technical field
The invention belongs to high speed chain-driven technical field, be specifically related to a kind of traitorous distance that is applicable to Coal Mechanical, metallurgical machinery, chemical machinery, oil-well rig and production process production line two-sided inside and outside compound engaging tooth shape chain drive system.
Background technique
The silent chain transmission is widely used in steady, low, the fast workplace of noise of various requirement motion, like fields such as motor car engine, Coal Mechanical, oil-well rigs.The product and the specification of silent chain are various, application very extensively, engaging tooth shape chain in silent chain is divided into by the difference of mesh mechanism usually, outer gearing silent chain, inside and outside several kinds of forms such as compound engaging tooth shape chain.
The most common silent chain is the outer gearing 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 accomplishes, and engagement process belongs to the engagement of non-rumble altogether.Because chaindriven polygon effect; Have that pitch lines and the pitch circle of sprocket wheel of the profile of tooth chain of outer gearing mechanism replace cut mutually or tangent; The chain position of center line presents periodic variation; This silent chain will produce big impact shock and noise when high-speed motion, have a strong impact on the performance of motor.
The silent chain transmission overwhelming majority is the single face engagement in the existing technology, and can't be applied to coal, petroleum machinery and production process production line transmission system etc. needs in the multiple axes system of S shape transmission.And mostly the chaindriven bearing pin of traditional profile of tooth be the round pin formula, and this silent chain does not have switches political loyalty apart from function, can not effectively reduce the chaindriven polygon effect of profile of tooth, and noise is bigger, serious wear, and kinematic accuracy is poor.
Application number be 200710016227.5 Chinese patent disclose a kind of have inside and outside the high speed Tooth Profile chain of compound mesh mechanism, but this silent chain can only be realized the single face engagement, can't be applicable in the middle of the multiple axes system that needs the transmission of S shape; Application number is that 200810128556.3 Chinese patent discloses a kind of two-sided engaging tooth shape chain; But adopt single round pin to connect between its adjacent link; Can not realize that profile of tooth is chaindriven traitorous apart from function, therefore chaindriven polygon effect of this profile of tooth and impact and vibration are big, wearing and tearing are serious, noise is higher, fatigue durability is poor.
Summary of the invention
The objective of the invention is to overcome the deficiency of traditional chain drive technology, provide a kind of have inside and outside compound mesh mechanism, pitch is variable and the traitorous distance of function such as multiple axes system S shape transmission two-sided inside and outside compound engaging tooth shape chain drive system.The present invention realizes through following technological scheme:
Compound engaging tooth shape chain drive system inside and outside a kind of traitorous distance is two-sided mainly is made up of chain 1, sprocket wheel A2 and sprocket wheel B3.One side of chain 1 and sprocket wheel A2 engagement driving, the opposite side of chain 1 and sprocket wheel B3 engagement driving, the transmission of realizable force and moment of torsion.
Described chain 1 mainly by many groups work carrier bar 10, weak point rolls pin 11, length is rolled pin 12 and guide card 13 is formed.Wherein, short roll pin 11, longly roll the chain plate hole that pin 12 passes work carrier bar 10 many groups work carrier bar 10 head and the tail are connected, the exposed portions serve that guide card 13 rolls pin 12 two ends with two adjacent length is fixed.
Above-mentioned location offset angle γ is a chaindriven important parameter, and so-called " location " refers to the angle that rolls initial mounting point of pin and carrier bar center line.In the chain operation process, the angle that rolls pin and carrier bar center line is to change constantly, but the angle of this variation can be referred to as " offset angle ", but not " location offset angle ".
Described work carrier bar 10 has last flank profil 100 and following flank profil 101.When sprocket wheel A2 was drive sprocket, the gear teeth of sprocket wheel A2 at first meshed with last flank profil 100, then through the gear teeth meshing transmission of flank profil 101 and driven sprocket B3 down, thereby output power on the sprocket wheel B3; When sprocket wheel B3 was drive sprocket, the gear teeth of sprocket wheel B3 at first meshed with following flank profil 101, then through the engagement driving of last flank profil 100 with sprocket wheel A2, thereby output power on the sprocket wheel A2, so the present invention can realize the transmission of S shape.
The inboard flank profil 102 of described work carrier bar 10 is the circular arc of evagination; Outside flank profil 103 is a straight line, and inboard flank profil 102 is δ with respect to the overhang of outside flank profil 103, and the δ span is 0.10mm≤δ≤0.30mm; When chain 1 and sprocket engagement; The inboard flank profil 102 of work carrier bar 10 at first meshes with sprocket teeth, with the rotation of sprocket wheel, progressively carries out the transition to outside flank profil 103 and sprocket teeth engagement; Finally be positioned on the sprocket teeth until outside flank profil 103, thus realized of the present invention inside and outside compound mesh mechanism.
Beneficial effect of the present invention:
(1) realized traitorous distance two-sided inside and outside compound engaging tooth shape chaindriven traitorous apart from function, significantly reduce the polygon effect of this silent chain and impact with vibration, alleviate wearing and tearing, reduction noise, the fatigue durability of raising silent chain;
(2) realize the to switch political loyalty S shape transmission agency of inside and outside two-sided compound engaging tooth shape chain;
(3) possessed interior engaging tooth shape chain simultaneously and meshed steadily and the advantage of outer gearing silent chain positioning stablity, made that the chain polygon effect significantly reduces, buffer capacity strong, running is steady, long service life, be specially adapted to the operating mode of high speed and speed change, variable load.
