Box body interlayer water-cooled type small-tooth-difference 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 water-cooled type small-tooth-difference reducer box of a heavy duty plate feeder. The box body interlayer water-cooled type small-tooth-difference 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 water-cooled type small-tooth-difference 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 an interlayer; a water inlet valve and a water outlet valve are arranged at the top and on the lateral portion of the box body respectively; 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 and comprises an inner gear ring and a small gear. According to the box body interlayer water-cooled type small-tooth-difference reducer box of the heavy duty plate feeder, the heat of an interlayer water sleeve is discharged from the water outlet valve and emitted out of the box body, the water can be adjusted to increase the heat efficiency, a main box body is unchanged, and only the inner meshing gear pair speed ratio needs to 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 water-cooled heavy-duty apron feeder gear box with a small tooth difference between the box interlayers . 【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...
