Motor reduction gearbox

Abstract

The invention provides a motor reduction gearbox and belongs to the technical field of gearboxes. The motor reduction gearbox solves the problem that the noise pollution is serious when the existing motor reduction gearbox works. The motor reduction gearbox comprises a gearbox box body, an end cap and a gear reduction mechanism, wherein the end cap is matched with the box body, a containing cavity is formed between the gearbox box body and the end cap, the gearbox reduction mechanism is arranged in the containing cavity, a lower annular noise enclosure is fixedly connected with an inner end surface of the gearbox box body, the annular noise enclosure is arranged on the gear reduction mechanism in an encircling mode, and an upper annular noise enclosure which is matched with the lower annular noise enclosure is fixedly connected with the inner end surface of the end cap. The motor reduction gearbox has the advantages of being small in noise, high in intensity, and good in oil sealing performance.

Description

technical field [0001] The invention belongs to the technical field of gear boxes, and relates to a motor reduction gear box. Background technique [0002] The use of the existing reduction gear box is more and more extensive, and along with the technical problems existing in the reduction gear box are continuously solved and overcome, the structure of the reduction gear box is more and more mature. [0003] The existing motor reduction gear box generally includes a gear box body, an end cover matched with the box body, and a gear reduction mechanism. A housing cavity is formed between the gear box body and the end cover, and the gear reduction mechanism is arranged in the housing cavity. The gear reduction mechanism has multi-stage gear reduction, and its gear structure is lubricated by lubricating oil. The gearbox box and the end cover are fixed and installed together by bolts, but there are some problems: the gears will generate relatively large noise during transmission....

Problems solved by technology

[0003] The existing motor reduction gear box generally includes a gear box body, an end cover matched with the box body, and a gear reduction mechanism. A housing cavity is formed between the gear box body and the end cover, and the gear reduction mechanism is arranged in the housing cavity. The gear reduction mechanism has a multi-stage gear reduction, and its gear structure is lubricated by lubricating oil. The gearbox box and the end cover are fixed and installed together by bolts, but there are some problems: the gears will generate relatively loud noises during transmission. , and the sound insulation effect of the gearbox box and end cover is not good, resulting in relatively loud noise in the surrounding working environment, resulting in noise pollution
