The utility model discloses a driving chain chain is with conical surface wheel area of contact is big and the contact surface coincidence is good, and transmission power is big, on transmission torque is big, can be used for large -scale car and wind generating set's transmission, is worth promoting.
Description
Technical field
The invention belongs to mechanical engineering technical field, be specifically related to a kind of high-torque chain of variable drive.
Background technology
In the prior art, the transmission efficiency of chain of variable drive is the highest, but the axle two ends that existing driving-chain only has chain can contact with wheel face.Owing to contact area is the least, transmission moment is the least, is only used for kart, too far behind to catch up to powerful wind-power electricity generation.
Summary of the invention
For making up the deficiencies in the prior art, the present invention provides one to make chain and cone pulley contact area is big, driving torque is big, transmits high-power high-torque chain of variable drive.
The present invention is achieved through the following technical solutions:
A kind of high-torque chain of variable drive, it is characterized in that and includes outer link and inner link, described outer link includes two pieces of outer plates, the inner side of every piece of outer plate is provided with the chain rivet of half hollow, by rivet through two half hollows chain rivet by two panels outer plate docking riveted and an outer link, the two ends of chain link are provided with the hole being rotatably assorted with chain rivet, and the half chain rivet of two panels outer plate from chain link both sides load hole, completes a chain of entirety respectively after riveted；The outer surface of described outer plate is inner conical surface.
The high-torque chain of variable drive of the present invention, described outer link both sides are provided with conical surface wheel, the inner conical surface parameter of outer plate outer surface is identical with parameter at the conical surface wheel mean radius matched, i.e. curvature at mean radius is identical, when chain works in mean radius, fit with conical surface wheel surface in outer plate surface, contact area is maximum, gearing friction moment is maximum, when chain is in conical surface wheel small end work, at conical surface wheel work, radius of curvature diminishes, the bilge radius of outer plate is more than the radius of curvature at conical surface wheel work, line contact on bus is taken turns at two conical surfaces, outer plate is designed with suitable elasticity, micro-strain is produced under the pressure of both sides conical surface wheel, form flexible contact areas under stress, produce strong frictional force.When chain is in the big end work of conical surface wheel, outer plate outer surface radius of curvature is less than the radius of curvature at conical surface wheel work, outer plate two ends contact with conical surface wheel surface, this is the EDGE CONTACT that non-co-is gripped, owing to radius is the biggest, also it is flexible contact areas, after outer plate two ends start by conical surface wheel pressure, extends to centre after micro-strain and be connected, the cornerite of the major diameter transmission in transmission is the biggest, and work chain link skidding in transmission does not occur at big end.
The invention has the beneficial effects as follows: the chain of the present invention is long-pending with conical surface wheel tread big and contact surface repeatability is good, the outside of outer plate is 5:1 with chain rivet face area ratio, the driving-chain transmission power of the present invention is big, bigger than prior art buncher driving-chain more than 5 times of driving torque, can be used for the transmission of large car and wind power generating set.

Accompanying drawing 1 is the structural representation of the present invention.
Accompanying drawing 2 is the sectional view of Section A-A in accompanying drawing 1.
Accompanying drawing 3 is the sectional view of section B-B in accompanying drawing 1.
In figure, 1 outer plate, 2 chain links, 3 rivets, 4 fixed axoid wheels, 5 move conical surface wheel, 6 chain rivets.
Detailed description of the invention
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings.
Accompanying drawing is a kind of detailed description of the invention of the present invention.This embodiment includes outer link and inner link 2, described inner link 2 two ends have two holes, described outer link includes two pieces of outer plates 1, the inner side of every piece of outer plate 1 is provided with the chain rivet 6 of half hollow, the symmetrical Kong Zhonghou loading inner link 2 two ends of the chain rivet 6 of relative two pieces of outer plates 1 docks and passes through rivet 3 riveted, forming an overall chain, hole is to coordinate with chain rivet 6；The outer surface of described outer plate 1 is inner conical surface, and the inner conical surface parameter of outer plate 1 outer surface is identical with parameter at conical surface wheel mean radius.
The chain of the present embodiment, when the speed ratio that works is a pair, works at the mean radius of conical surface wheel, the outer surface of outer plate 1 and fixed axoid wheel 4 and the conical surface laminating of mobile conical surface wheel 5, produces big moment of friction.nullWhen the work speed ratio of chain is not equal to 1，Chain takes turns position contrast at two pairs of conical surfaces，The small end work that one, chain is taken turns at the conical surface，Other end is when big end work，Chain in small end work，Cornerite is smaller，The radius of curvature of outer plate 1 outer surface is bigger than the radius of curvature of fixed axoid wheel 4 and mobile conical surface wheel 5，Take turns at two conical surfaces and on bus, produce conjugate line contact，Produce flexible contact areas，Produce the biggest frictional force，The other end of chain holds greatly work what the conical surface was taken turns，Cornerite is bigger，The outer cone radius of curvature of fixed axoid wheel 4 and mobile conical surface wheel 5 is more than the inner conical surface radius of curvature of outer plate 1，Produce non-conjugated contact，At outer plate 1 two ends line contact，Light deformation is produced after being stressed，Form edges at two ends contact area，Bigger pressure can be born，Produce moment of friction，What the present invention improved moment is to contact increase with conical surface wheel because have two: one，The outside of outer plate 1 is 5:1 with chain rivet 6 face area ratio；Two is that contact surface repeatability is good, the present invention be the conical surface take turns to the conical surface, and prior art perfect condition be plane to the conical surface, so pressure can strengthen.Therefore big more than 5 times of the torque ratio prior art buncher driving-chain of the present invention, can be used for the transmission of large car and wind power generating set, and transmission efficiency is high.
