【Abstract】 The straight moving push rod linear reducer is a kind of new typed transmission mechanism,in which the rack is one of the key components of this mechanism.The setting up situation of optimal mothematical model of tooth profile curve of rack in this installation is discussed when the installation is being applied separately to the occasion of low speed and heavy load,movement of high velocity and of rather big vibration and unstable working circumstances.And take emphatically the case of applying this installation to low speed and heavy load circumstances as an example,the concrete optimal computation is realized by carrying on adaptation approaching method on rack tooth profile using cubic spling function,thus obtained optimal curve of tooth profile with fairly good practicality.At the same time it is verified that the obtained curve of tooth profile is an optimum by means of comparing with the results obtained from several other known curves of rack tooth profile.更多还原
