由于齿轮传动，齿轮间隙是客观的存在，间隙使产生时间滞后，对电气调速造成影响。

Gear clearance exists objectively due to gear drive. Time lag results from the clearance, which also has influence on electric speed regulation system.

同时，针对由齿轮间隙引起的两冲辊之间(即凸、凹模之间)相位角的变化，提出设计角度调整机构的理念。

Meanwhile, it puts forward the conception of Angle adjusting mechanism from the fact that the wheel clearance could lead the changes of phase-angle between two roller.

齿轮尾部间隙可调：NY P高粘度泵可以根据粘度的需要，通过调节齿轮间隙，达到泵在不同黏度下的工艺要求。

Adjustable gear tail: NYP can need according to the viscosity, high viscosity pump by adjusting the gear clearance, to pump under different viscosity process requirement.
