Embodiment
Embodiments of the invention as shown in Figure 1, Figure 2, Figure 3 shows.
The present invention has carried out novelty improvement on metal band type or metallic chain type non-stage transmission basis, increases metal tape or the frictional force between chain and cone pulley, as shown in Figure 1 by the conical surface of cone pulley being designed to pyramidal surface.Pyramidal surface can increase metal tape or the frictional force between chain and cone pulley by equidistant crest line, thus reduces the skidding in transmission process, and can increase the torque of variable transmission, improves its power transmission ability.
The corner angle of adjacent two planes of pyramidal surface are 175
0-178
0, the cone angle between adjacent two crest lines is 22.5
0.Cone angle determines the plane number of composition pyramidal surface, and this plane number can not be too much, and the pyramidal surface Roughness of cone pulley too much can be made excessive, and when to cause in transmission process metal chain turnover cone pulley, transmission is unstable; And plane number can not be very few, I haven't seen you for ages excessively causes the design effect of this design method not remarkable.Corner angle determine the Roughness of pyramidal surface equally, and therefore, this angle size when designing is also moderate, crosses conference and makes the pyramidal surface Roughness of cone pulley excessive, and when to cause in transmission process metal chain turnover cone pulley equally, transmission is unstable; The too small design effect of this design method that can cause equally is not remarkable.Therefore, in the present invention, corner angle are designed to 22.5
0, namely the pyramidal surface of each cone pulley is made up of 16 planes respectively, and corner angle are designed to 175
0-178
0between.
The present invention can be applicable to oscillating tooth infinitely variable speed transmission, and before oscillating tooth cone pulley runs, slide plate is in oscillating tooth groove, as shown in Figure 2.When oscillating tooth cone pulley runs, rely on centrifugal action, slide plate throws away from oscillating tooth groove, is in outside extended configuration, and the slide plate thrown away can be meshed in the engaging tooth of tooth profile metal chain, as shown in Figure 3.But for movable-tooth stepless speed transmission, starting stage centrifugal force be not enough to make slide plate throw away oscillating tooth groove come with the engaging of sprocket time, there is skidding between metal chain and cone pulley.Therefore, the cone pulley of movable-tooth stepless speed transmission can be designed to above-mentioned pyramidal surface equally, and make it rely on the friction driving between metal chain and cone pulley in the starting stage by clamping force, the design of pyramidal surface can reduce axial clamping force to a certain extent while increasing friction force, the i.e. demand of hydraulic pressure installation, reduce hydraulic slip, improve transmission efficiency.
