Embodiment Construction

[0063] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0064]The design method of high-order modified eccentric circular gear and its conjugate non-circular gear pair, the specific steps are as follows:

[0065] Step 1, such as Picture 1-1 and 1-2 As shown, the pitch curve equation of high-order modified eccentric circular gear 1 is established. The pitch curve of high-order modified eccentric circular gear 1 is changed by n 1 It is composed of nodal curve segments, and each nodal curve segment includes an asymmetric first denatured curve segment r 11 and the second denatured curve segment r 12 ;Angular displacement of high-order denatured eccentric gear 1 The corresponding radial direction in the first change cycle is ( The radial expressions corresponding to the remaining change periods are consistent with those of the first change period):

[0066]

[0067] In the formula, R is the radius of ...

Abstract

The invention discloses a design method of a high-order modified eccentric circular gear and a non-circular gear pair conjugated with the high-order modified circular gear. There is no literature report on design and application research on a high-order modified eccentric circle-non-circular gear pair so far. The design method specifically comprises the following steps that firstly, a pitch curve equation of a high-order modified eccentric circle gear and a non-circular gear pair conjugated with the high-order modified eccentric circle gear is established, and a center distance is calculated through the numerical method; secondly, the concavity and convexity of a pitch curve are verified, the maximum modulus under the situation that undercutting is not carried out when a gear is machined through the gear shaping method is obtained, the pressure angle change range is calculated, the maximum pressure angle value is verified, and the contact ratio when the high-order modified eccentric circle gear and the non-circular gear pair conjugated with the high-order modified eccentric circle gear are meshed is calculated. According to the design method, a whole set of thorough design theoretical basis is provided for the high-order modified eccentric circle gear and the non-circular gear pair conjugated with the high-order modified eccentric circle gear in actual application, and the using and popularizing of the high-order modified eccentric circle gear and the non-circular gear pair conjugated with the high-order modified eccentric circle gear are promoted.

Description

technical field [0001] The invention belongs to the technical field of mechanical gear transmission, and relates to a design method of a non-circular gear pair, in particular to a design method of a high-order modified eccentric circular gear and its conjugate non-circular gear pair. Background technique [0002] Non-circular gear mechanism, cam mechanism and connecting rod mechanism can realize non-uniform speed transmission, but non-circular gear has the advantages of high transmission efficiency, stable movement, reliable operation, etc., and has been widely used in many fields. [0003] In the research of high-order modified eccentric circular gears and their conjugate non-circular gears, the existing engineering practical applications mainly include first-order eccentric circular-non-circular gear mechanisms and first-order modified eccentric circular-non-circular gears in rice transplanters. There are also examples of using first-order eccentric circle-multi-order non-...
