本准无级变速机构为一变直径式链传动近似的无级变速装置,是一啮合式无级变速装置,可克服摩擦式无级变速机构的缺点,其优点是比摩擦式无级变速机构效率高、重量轻、寿命长、传动功率大;但它仍具有瞬时传动比变化等一般链传动的缺点。可用于对传动比精度要求不高的起重、运输、车辆等方面的传动,对某些生产自动线的传动也是合适的,是较简单、轻便的理想啮合式的近似无级变速机构。
The quasi-CVT mechanism is a variable-diameter chain drive approximation CVT device is a meshing CVT device to overcome the shortcomings of friction-type CVT mechanism, the advantage of friction than the CVT mechanism High efficiency, light weight, long life, high power transmission; but it still has the shortcomings of the general chain drive such as instantaneous transmission ratio changes. It can be used for hoisting, transportation, vehicles and other aspects with low transmission ratio accuracy. It is also suitable for some automatic transmission lines. It is a simple and lightweight ideal meshing type stepless speed change mechanism.
