| Full Text | This invention relates to a continuously variable transmission system, hereinafter also called a CVT system for the sake of brevity. The known CVT system is prone to the drawback that it has Low transmission efficiency. Another drawback of the known CVT system is that it is sensitive to lubrication requirement. The known CVT system has more number of parts in the driven part of the system rendering it cumbersome in use. The known CVT system involves more number of parts and is therefore correspondingly involves high production costs. This invention therefore proposes a CVT system which considerably minimizes the above mentioned drawbacks. Thus, the proposed CVT system is free from oil seals. O-rings and grease retaining components. The continuously variable transmission system, according to this invention, is characterized by a lubrication free arrangement; and a movably driven sintered boss, or mild steel boss with low friction coating, the boss and its face being attached together by an adhesive. The boss and the face have to be integral to transmit the belt torque to the shaft. That is to sat7, the face receives the torque from the belt and the boss transmits to the shaft. This invention will now be described with further reference to the accompanying drawings in which Fig. 1 illustrates the known CVT system and Fig.2 illustrates, by way of example, and not limitation, one of possible embodiments of the CVT system proposed herein. In the existing CVT system, oil seals S, O-rings R and movably driven cover C are provided as indicated. These components are eliminated in the CVT system proposed herein. In the known CVT system a mild steel boss M is provided and this boss needs lubrication. In the proposed CVT system, however, a movably driven sintered boss B which needs no lubrication is provided. The sintered boss B or mild steel boss with low friction coating is located in the place of the known mild steel boss M. The boss B and its movably driven face F are fixed to each other by an adhesive without resorting to welding. This reduces distortion and is also cost reducing during manufacture. Various other embodiments of this invention are possible without departing from the scope and ambit of this invention. We Claim: 1. A continuously variable transmission system characterised bv a lubrication free arrangement: and a movably driven sintered boss or mild steel boss with low friction coating, said boss and its face being attached together by an adhesive. 2. A continuously variable transmission system substantially as herein described and illustrated by the accompanying drawings. |
