The example of reverse engineering design of non-circular gear

According to the function of the mechanism in the seedling picking cycle, the whole movement is divided into four processes: seedling picking, seedling transplanting, seedling releasing and recovery, and the corresponding mechanism trajectory is also divided into four segments. The trajectory curve is fitted with cubic non-uniform B-spline curve....

Theoretical analysis of noncircular gears

Analyze each tooth of the meshing diagram of the driving wheel and driven wheel, number each tooth, as shown in Figure 1, measure the distance from the rotation center of the driving wheel and driven wheel to each tooth, and the angular velocity of the driven wheel is ω...

Kinematic analysis of noncircular gears

Using ADAMS software, the kinematics of non-circular gear is analyzed to verify whether the output transmission ratio of non-circular gear is consistent with the theoretical transmission ratio. Kinematic analysis can enable the designed products to be verified and analyzed in time. This verification does not require a lot of...

Non-circular gear modeling

1. Drawing of tooth profile of non-circular gear At present, the envelope method and tooth profile folding algorithm are mostly used to solve the non-circular gear, but the tooth profile conversion method has low precision and complex process, so it is used less and less. In this paper, the...

Example analysis of noncircular gear

Example analysis of noncircular gear: the equation of transmission ratio i12 to be realized is as follows: Where, the transmission ratio function is based on the rotation angle of the driving wheel φ 1 is the function of independent variable. In this paper, it is assumed that the module...

Noncircular gear transmission

The primary task of solving non-circular gear transmission is to determine the pitch curve, which is mainly divided into three ways: giving the transmission ratio function and center distance; Given reproduction function and center distance; The pitch curve equation and center distance of driving wheel are given. Instead of...
