Embodiment Construction

[0026] figure 1A top view of the grinding device of the present invention is briefly shown. A gear wheel with a conical surface 2 as workpiece 1 is clamped on a workpiece shaft 3 . The shift wheel 1 has a conical drive surface 2, ie the shift wheel is curved in only one direction. It is of course also possible to have a curved shape in both directions. A grinding wheel 4 is arranged on the grinding wheel spindle 5 for grinding the conical drive surface 2 of the transmission wheel 1 . The grinding wheel 4 and the grinding wheel axle 5 are arranged on the grinding wheel axle seat 6, so that the grinding wheel 4 can swing back and forth when the surface 2 is ground. For this purpose, a control device 7 is additionally provided, by means of which the rotational speed of the workpiece spindle 3 and the reciprocating pivoting of the grinding wheel 4 are controlled. When grinding the transmission surface of the transmission wheel 1, the grinding wheel 4 swings back and forth betw...

Abstract

The invention relates to a method for producing gear plates for a continuously variable gearbox wherein at least two gear plates with the transmission surfaces thereof are arranged in an opposite manner. When the gearbox is in operation, said transmission surfaces come into contact in a non-positive mode with a power transmission element, on a device comprising at least one workpiece spindle and a grinding disc which is driven by a grinding spindle in order to grind the transmission surface of at least one gear plate. During the grinding of the transmission surface, a repeated relative oscillating movement is carried out radially in relation to the workpiece spindle, between the grinding disc and the gear plate, in such a way that the grinding region of the grinding disc is moved back and forth between an inner radius and an outer radius of the transmission surface. The gear plate is rotated by means of the workpiece spindle in such a way that the entire transmission surface is ground.

Description

technical field [0001] The present invention relates to a method and a device for making a continuously adjustable transmission, such as a transmission wheel of a belt transmission. Background technique [0002] Such continuously adjustable transmissions are also referred to as CVT (continuously variable transmission) transmissions and have at least one pair of transmission wheels each having, for example, substantially conical or drum-shaped, i.e. arcuate, transmission-surfaces . The transmission surface refers here to the surface used for power transmission. The transmission surface has an arcuate or rectilinear shape in the radial direction of the transmission wheel. The mutual spacing of the transmission wheels arranged in pairs is adjustable, wherein between the transmission wheels the power transmission element, for example a detail chain, is reversed. Stepless adjustment is realized by adjusting the distance between the speed change wheels. Wherein the power trans...
