Description
技术领域technical field
本发明属于摩擦传动技术领域，特别是一种摩擦轮传动机构。The invention belongs to the technical field of friction transmission, in particular to a friction wheel transmission mechanism.
背景技术Background technique
摩擦轮传动是指利用两个或两个以上互相压紧的轮子间的摩擦力传递动力和运动的机械传动。摩擦轮传动可分为定传动比传动和变传动比传动两类。传动比基本固定的定传动比摩擦轮传动，又分为圆柱平摩擦轮传动、圆柱槽摩擦轮传动和圆锥摩擦轮传动三种型式，前两种型式用于两平行轴之间的传动，后一种型式用于两交叉轴之间的传动。工作时，摩擦轮之间必须有足够的压紧力，以免产生打滑现象，损坏摩擦轮，影响正常传动。Friction wheel transmission refers to the mechanical transmission that transmits power and motion by the friction force between two or more wheels that are pressed against each other. Friction wheel transmission can be divided into two types: fixed transmission ratio transmission and variable transmission ratio transmission. The fixed transmission ratio friction wheel drive with basically fixed transmission ratio is divided into three types: cylindrical flat friction wheel drive, cylindrical groove friction wheel drive and conical friction wheel drive. The first two types are used for transmission between two parallel shafts, and the latter One type is used for transmission between two cross shafts. When working, there must be enough pressing force between the friction wheels to avoid slipping, damage to the friction wheels, and affect normal transmission.
变传动比摩擦轮传动易实现无级变速，并具有较大的调速幅度。机械无级变速器多采用这种传动。但是变传动比摩擦轮传动比不准确、效率低、磨损大，而且通常轴上受力大，所以主要用于传递动力不大或需要无级调速的情况。The variable transmission ratio friction wheel transmission is easy to realize stepless speed change, and has a large speed regulation range. This type of transmission is mostly used in mechanical continuously variable transmissions. However, the variable transmission ratio friction wheel has inaccurate transmission ratio, low efficiency, large wear, and usually a large force on the shaft, so it is mainly used in situations where the transmission power is not large or stepless speed regulation is required.
