摘要

基于内、外啮合齿轮马达的结构特殊性,分析了泄漏的主要途径,通过泄漏的计算公式,分别对4种不同连接方式进行理论分析。同时搭建试验台对该马达进行容积效率进行测试,结果表明:齿轮马达的端面间隙泄漏与马达转速无关,只和马达进、出口的压差有关,伴随齿轮马达的连接方式不同,马达的径向间隙泄漏有微小改变;随着马达进、出口压差变大,马达内部的泄漏量逐渐增大,马达容积效率随之减小,机械效率随着马达进、出口压力的升高而逐渐增加。
        Based on the special structure of internal/external meshing gear motor,the main ways of leakage were analyzed. Through the calculation formula of leakage,four different connection modes were analyzed.Meanwhile,the test bed was built to measure the volume efficiency of the motor. The results show that the leakage of the end gap of the gear motor is independent of the motor speed,and it is only related to the pressure difference of the motor inlet and outlet. With gear motor connected in different ways,the radial clearance leakage has a tiny change. As the motor inlet and outlet pressure difference becomes bigger,the internal leakage of the motor gradually increases and the motor volume efficiency decreases. The mechanical efficiency increases with the increase of the pressure of the motor inlet and outlet. The conclusion is significant for the design,manufacture and use of the internal/external meshing gear motor.
