Speed reducer and box thereof

Abstract

The invention provides a speed reducer and a box thereof. The box of the speed reducer comprises a box body and an oil tank for the bottom end of a probing rod of an oil level sensor to extend into, wherein the oil tank is welded on the box body and is provided with a top exhaust hole and an open oil through hole communicated with an oil sump of the box body. The size of the oil tank is not limited by fixing firmness of a pipe holding connector, so that the size of the oil tank is designed to be larger by utilizing the internal space inside the box body of the speed reducer, the distance between a floating detection device on the probing rod and the inner wall of a steel pipe is increased, and further the problem that the oil level sensor gives a false alarm due to high oil viscosity or impurities is solved. In addition, when the oil level sensor is installed on the box body of the speed reducer, only the oil level sensor is needed to be screwed into the installing hole formed in the box body of the speed reducer without external arrangement and installation of the steel pipe, and both installation and maintenance are more convenient.

Description

technical field [0001] The present invention relates to the technical field of reducers, more specifically, to a reducer casing, and also relates to a reducer with the above-mentioned reducer casing. Background technique [0002] The reducer is provided with an oil level sensor, which is used to detect whether the oil level in the reducer case is normal. The traditional oil level sensor is installed in the steel pipe. The lower end of the oil level sensor is a probe rod with a floating detection device. When installing the oil level sensor, install the steel pipe first, and then screw in the oil level sensor. The above-mentioned steel pipes are fixed on the reducer casing through the holding pipe joints, one end of the holding pipe joints is screwed into the reducer, and the other end is tightly held with the steel pipes. [0003] In order to ensure the fastening of the pipe joint to the steel pipe, the size of the steel pipe is small, with an inner diameter of 30-31mm, wh...
