Abstract

A maintenance information output system is provided that includes an iron amount detecting device, a receiver, a maintenance information output apparatus, and a controlling portion. The iron amount detecting device is attached to a speed reducer, and detects an amount of iron in a lubricant in the speed reducer. The receiver receives data of the amount of iron detected by the iron amount detecting device. The maintenance information output apparatus has an outputting portion which outputs maintenance information of the speed reducer. The maintenance information output apparatus has a receiving portion which receives the data from the receiver. When the amount of iron is equal to or larger than a threshold value, the controlling portion causes the outputting portion to output the maintenance information.

Claims

1. A maintenance information output system comprising:

an iron amount detecting device which is attached to a speed reducer, and which detects an amount of iron in a lubricant in the speed reducer;

a wireless receiver which receives data of the amount of iron detected by the iron amount detecting device; and

a maintenance information output apparatus including;

an outputting portion which outputs maintenance information of the speed reducer,

a wired receiving portion which receives the data from the wireless receiver, and

a controlling portion which, when the amount of iron is equal to or larger than a threshold value, causes the outputting portion to output the maintenance information, wherein the controlling portion functions during operation of the speed reducer.
