Box body interlayer air-cooled type planetary gear reducer box of heavy duty plate feeder

Abstract

The invention relates to the improvement of DT type feeder reducers, particularly to a box body interlayer air-cooled type planetary gear reducer box of a heavy duty plate feeder. The box body interlayer air-cooled type planetary gear reducer box comprises a box body, an input shaft, a transmission mechanism and an output shaft, wherein the input shaft, the transmission mechanism and the output shaft are arranged in the box body. The box body interlayer air-cooled type planetary gear reducer box is characterized in that a connecting part of an inner cylinder and a circular end cover is arranged in the box body; the inner cylinder is connected with an output end of the box body; an outer circle of an input end of the circular end cover is in interference fit with an inner hole formed at an input end of the box body; the input end of the circular end cover is connected with the input end of the box body through a circular casing in a sealing mode; the inner wall of the box body and the outer wall of the connecting part of the inner cylinder and the circular end cover form into an interlayer; the lateral side of the box body is provided with a fan; the top of the box body is provided with an air outlet; the input shaft and the output shaft are supported in the circular end cover and the inner cylinder through a bearing respectively; the transmission mechanism comprises a planetary gear, an inner gear ring, an eccentric bearing and a cylindrical pin; an inner meshing pair is arranged in the circular casing. According to the box body interlayer air-cooled type planetary gear reducer box of the heavy duty plate feeder, the heat in the interlayer is discharged from an exhaust window and simultaneously transmitted to the box body to be emitted out of the box body and accordingly the integral box body is cooled, the thermal power is high, the structure is simple, the cost is low, and the inner meshing ratio can be changed to obtain a series of products.

Description

【Technical field】 [0001] The present invention relates to the improvement of the prior art DT heavy-duty apron feeder combined suspension special reducer (abbreviated as DT-type feeder reducer), and specifically relates to a box interlayer air-cooled heavy-duty apron feeder star wheel reducer . 【Background technique】 [0002] Apron feeders are widely used in crushing and grading workshops of large-scale mineral processing plants, as continuous or uniform feeding from self-storage silos to primary crushers, and as short-distance transport for reloading. For example, it is used to directly feed ore into large vehicles at the bottom of the mine shaft, and it is used to continuously and evenly feed and load each truck from the raw material warehouse. [0003] DT type feeder reducer is a special reducer successfully designed by the Transmission Machinery Research Institute of NHI with reference to the technology of Flender, Germany. It adopts a three-stage orthogonal reducer and...
