[0002] [0002]
背景技术 Background technique
[0003] 随着无刷电机技术的日益成熟和应用的日益广泛， 使电机的使用寿命成倍的提 高。 从而对减速箱的寿命要求也越来越高。 因为电机与减速箱通常是成对使用 。 行星减速在减速箱中由于重量轻、 体积小、 传动比范围大、 效率高、 运转平 稳、 扭矩大、 噪声低适应性强等特点而广泛被各行业选用。 但现有的行星减速 箱由于原有结构的局限性工作中有如下缺陷： [0003] As the brushless motor technology becomes more mature and widely used, the service life of the motor is doubled. As a result, the life expectancy of the gearbox is also increasing. Because the motor and the gearbox are usually used in pairs. Planetary deceleration is widely used in various industries due to its light weight, small size, large transmission ratio range, high efficiency, stable operation, high torque, and low noise adaptability. However, the existing planetary reduction gearbox has the following defects due to the limitations of the original structure:
技术问题 technical problem
[0004] 1、 工作部位油脂会通过输出轴行星架与内齿圈的齿槽向输出端的空隙流动。 [0004] 1. The oil at the working part flows through the gap between the output shaft carrier and the tooth groove of the ring gear to the output end.
[0005] 2、 工作部位油脂会通过齿槽向电机方向流进电机连接法兰的螺纹孔等空隙， 通过马达齿的空隙向马达轴承处流动。 [0005] 2. The oil at the working part will flow into the gap of the screw hole of the motor connecting flange through the tooth groove in the direction of the motor, and flow to the motor bearing through the gap of the motor tooth.
[0006] 由于上述缺陷会导致以下问题， 第一， 油脂向输出轴方向流动会污染输出轴轴 承， 同吋过多油脂会流到减速箱外， 还会污染其他部件。 第二， 油脂流向马达 轴端则会污染马达， 严重会影响马达性能， 甚至马达失效。 第三， 由于行星减 速箱工作部位油脂在它的寿命周期中只能加注一次油脂， 所以油脂质量和流失 与否对行星减速箱的寿命是关键， 油脂的流失， 将大大缩短减速箱的使用寿命 问题的解决方案 [0006] The above-mentioned defects may cause the following problems. First, the flow of grease to the output shaft contaminates the output shaft bearing, and too much grease will flow out of the reduction box and contaminate other components. Second, the flow of grease to the shaft end of the motor can contaminate the motor, severely affecting motor performance and even motor failure. Third, since the grease in the working part of the planetary gearbox can only be filled with grease once in its life cycle, the quality and loss of grease is the key to the life of the planetary gearbox. The loss of grease will greatly shorten the use of the gearbox. Life problem solution
