Abstract

A method for analyzing belt row torque of conical friction element includes: establishing belt-row torque analysis model of conical friction element, determining flow field boundary between conical friction elements and modifying calculation model of belt-row torque of conical friction element, according to the loss of the tapered friction element in idle state, establishing the analysis model ofthe tapered friction element torque by considering the configuration characteristic parameters of the tapered friction element and the working conditions of the tapered friction element, such as the clearance of the tapered friction element, the flow rate of lubricating oil and the relative rotational speed, etc, determining the boundary of the flow field between the conical friction elements, using the finite element method to calculate the torque of tapered friction element, and modifying the model of tapered friction element by comparing with the numerical calculation method, and developping a new method of tapered friction element torque analysis. The method can be used not only to calculate the torque of tapered friction element at low speed but also to evaluate the loss of tapered friction element at different configurations and working conditions, which can be used as the basis for the design of comprehensive performance of tapered friction element.

Description

technical field [0001] The invention relates to the technical field of torque design of a conical friction element, in particular to a method for analyzing the tapered torque of a tapered friction element, which is suitable for tapered loss analysis and structural optimization design of the tapered friction element. Background technique [0002] The conical friction element is a new type of friction element with the characteristics of a cone ring on the surface. Compared with the flat friction element, the conical friction element uses the conical surface to transmit torque. The conical ring configuration provides more friction area, which can effectively improve the friction torque. However, in the idling process of the friction element, the belt row loss is unavoidable, and the belt row loss will reduce the mechanical efficiency of the transmission device. The belt discharge torque is affected by structural parameters, working conditions, lubricating oil characteristics, ...
