Problems solved by technology

However, due to the influence of various random factors (such as manufacturing and assembly errors of gears, shafts and bearings), there will always be errors in the rotation angle of the output shaft during the transmission process of the gear system.
As a result, the gear transmission system produced according to the theoretically feasible design scheme often has deviations in motion performance in engineering applications and cannot achieve the expected functions, resulting in waste of resources and even serious accidents.

Abstract

The invention provides an involute cylindrical gear system transmission accuracy reliability determining and controlling method and belongs to the technical field of mechanical product design. According to the national standard, the involute cylindrical gear system transmission accuracy reliability determining and controlling method can help an enterprise to forecast failure probability of a gear system and make a reasonable improved plan to improve product reliability through detection of original errors of the gear system and analysis and control of transmission accuracy reliability of an involute cylindrical gear system, thereby saving cost and preventing resource waste and failure occurrence.

Description

technical field [0001] The invention belongs to the technical field of mechanical product design, and in particular relates to a method for determining and regulating the reliability of transmission precision of an involute cylindrical gear system. Background technique [0002] Reliability refers to the ability of a product to complete specified functions within a specified time and under specified conditions. Measuring this ability in a probabilistic way is called reliability. Since Robert Lusser put forward the scientific definition of reliability in San Diego, USA in 1952, reliability has been widely valued as a new comprehensive engineering discipline for more than 60 years. During this period, reliability technology was widely used in the design and development of mechanical products (such as aerospace vehicles, numerical control machine tools, vehicles). [0003] Especially in recent years, sustainable development has become the focus of global attention, and new ind...
