Based on the space curve meshing theory, a lightweight line gear mechanism (LLGM) was proposed in this paper. The LLGM can achieve the objective of lightweight design by reducing the radial dimension of the gear, which has an improvement in terms of size reduction. The outstanding advantage of the LLGM is its ability to achieve a high transmission ratio. Three aspects were proposed to design the LLGM: first, the primary design method was obtained; second, an approach to simply and effectively establish the analytical model of the LLGM was presented, which showed that the lightweight characteristic of the LLGM is mainly reflected in the radial dimension; third, the discriminant condition of the LLGM was built. The simplicity and effectiveness of the LLGM were demonstrated by a design example, while gear contact simulation and kinematics experiments were carried out to verify the theoretical basis. The lightweight design method proposed in this paper belonged to structural lightweight design, which can effectively solve the lightweight design issue in gear transmissions characterized by light loads and high transmission ratios.

Abstract

Na osnovi teorije ozobljenja prostorskih krivulj je v tem članku predstavljen lahek linijski zobniški mehanizem (LLZM). LLZM omogoča dosego lahke konstrukcije z neposrednim zmanjšanjem radialne mere zobnika, kar zagotavlja pomembno izboljšavo glede zmanjšanja velikosti. Posebna prednost LLZM je možnost doseganja visokih prenosnih razmerij. Za zasnovo LLZM so bili predlagani trije vidiki: prvič, določena je bila osnovna metoda zasnove; drugič, predstavljena je bila enostavna in učinkovita metoda vzpostavitve analitičnega modela LLZM, ki je pokazala, da se lahka zasnova LLZM odraža predvsem v zmanjšanju radialnih mer; tretjič, postavljen je bil kriterij za presojo ustreznosti LLZM. Preprostost in učinkovitost LLZM sta bila prikazana s konkretnim primerom zasnove ter preverjena s simulacijo zobniškega stika in kinematičnimi poskusi, ki potrjujejo teoretične osnove. Metoda zasnove, predstavljena v tem članku, spada med strukturne metode lahke zasnove in učinkovito rešuje problem lahkih zobniških prenosov, ki prenašajo majhne obremenitve in zagotavljajo visoka prenosna razmerja.
