Working principle

•RV transmission is a new transmission developed on the basis of transmission of cycloidal-pin wheel.

•RV reducer is composed of two parts: involute cylindrical gear planetary speed reducer and cycloidal-pin wheel planetary speed reducer.

•The involute planetary gear and the crank shaft are connected together as input of transmission part of the cycloidal-pin wheel.

•The crank shaft drives the cycloidal wheel to have eccentric motion.

•The crank shaft rotates a circle in the clockwise direction while the cycloidal wheel moves one tooth along the counter clockwise direction.

•The core parts of the RV reducer are the pin gear housing, the crank shaft and the cycloidal wheel.

齿隙与空程

回滞曲线:输入端固定,输出端施加转矩,得到转矩与扭转角的对应关系。
齿  隙:回滞曲线上,转矩为“零”处的扭转角。
空  程:回滞曲线上,转矩为“±3%额定转矩”处的扭转角。


 

效率

所有 E 系列减速机在额定状态下,效率>80%。

40E 效率举例:

噪音

减速机在额定状态下运行,噪音<75 分贝。

噪音大小与安装精度、润滑、温度、负载等因素有关。


寿命

减速机在额定状态下运行,寿命>6000 小时。

不宜长时间在超过额定转速或额定转矩的情况下运行,否则寿命会降低。

为保证减速机精度和寿命,请每隔 2000 小时运行后更换油脂。
