行星齿轮箱和轴承游隙监测系统
Abstract:
一种行星齿轮箱和轴承游隙监测系统，行星齿轮箱包括行星轮组件（20）、行星架（33）、第一传感器组件（40）和第二传感器组件（50），行星轮组件（20）包括互相套设的第一圈和第二圈，第一传感器组件（40）包括第一传感器（41）和第一天线（42），第一传感器（40）固定于第一圈并用于测量第一圈的温度，第二传感器组件（50）包括第二传感器（51）和第二天线（52），第二传感器（51）固定于第二圈并用于测量第二圈的温度，第二天线（52）呈环形且固定于行星轮组件（20）的行星齿轮圈（21）的轴向端面。通过该行星齿轮箱，轴承的第一圈和第二圈的温度能够被直接测量，从而有助于监测轴承游隙。
Abstract(English):

A planetary gearbox and a bearing clearance monitoring system. The planetary gearbox comprises a planet gear assembly (20), a planet carrier (33), a first sensor assembly (40), and a second sensor assembly (50). The planet gear assembly (20) comprises a first ring and a second ring sleeved with each other. The first sensor assembly (40) comprises a first sensor (41) and a first antenna (42). The first sensor (40) is fixed on the first ring and used for measuring the temperature of the first ring. The second sensor assembly (50) comprises a second sensor (51) and a second antenna (52). The second sensor (51) is fixed on the second ring and used for measuring the temperature of the second ring. The second antenna (52) is annular and is fixed on an axial end face of a planetary gear ring (21) of the planet gear assembly (20). By means of the planetary gearbox, the temperature of first and second rings of a bearing can be directly measured, thereby facilitating monitoring a bearing clearance.
