Flat disc CVT gear design
Abstract
Develop a kind of spreading to move the big twisting the torque with the gearbox of CVT of the big power, make its can satisfy the passenger car to use the request with the lorry. Pass the analysis the new rolling a round the even dish type have no class gearbox, having the possibility, canning satisfy the passenger car spread to move the request with the lorry. Including the cent remits the construction that spread moves the pattern to design; spreading the kinetic energy dint compute;spreading to move the efficiency compute; getting in touch with the contact of the area should the dint compute;and choose the appropriate material;rolling a strength of peaceful dish;limited a design for just degree with tired life span computing; automatically adding pressing device; add the loading that press the ability, extreme limit of the bearings turns soon with the calculation of the life span.
Keywords: type of roller CVT separate the flows roller dish
