Problems solved by technology

The biggest limitation of the above two transmission mechanisms is that they can only realize the motion and power transmission between plane cross axes, but cannot realize the motion and power transmission between two parallel axes in the plane
Therefore, their scope of use is greatly limited, and the most widely used parallel shaft transmission method in mechanical transmission cannot be realized.

Abstract

The invention relates to a hook rod gear mechanism for parallel shaft transmission. The hook rod gear mechanism comprises a transmission pair composed of a driving wheel and a driven wheel. The axis of the driving wheel and the axis of the driven wheel are parallel to each other. The driving wheel is connected with an input shaft. The driven wheel is connected with an output shaft. Driving hook rods on the driving wheel are evenly distributed in the circumference of the cylindrical end face of the driving wheel. Driven hook rods on the driven wheel are also evenly distributed in the circumference of the cylindrical end face of the driven wheel. The driving hook rods and the driven hook rods are each in a cylindrical spiral linear shape. When the driving wheel and the driven wheel are installed, the driving hook rod and the driven hook rod in one pair are meshed, the driving wheel is driven by a driver to rotate, the continuous and stable meshing is completed through the meshed hook rods, and transmission between the two parallel shafts is achieved. The spiral linear shapes of the driving hook rods and the driven hook rods can be determined according to the installation spatial coordinate system, the transmission ratio and other parameters of the driving wheel and the driven wheel and according to the hook rod contact line equation. The hook rod gear mechanism is simple in structure, fewer in transmission mechanism part, small in size, light in weight, large in transmission ratio, stable in transmission and suitable for being applied to the fields of mini machines and micro machines.
