Abstract

The invention discloses a speed reducer for a development machine, comprising a shell (1) and an input shaft, wherein the outer end part (2) of the input shaft is sheathed on a bearing seat (3); the speed reducer is further provided with a cooling device (4); the cooling device (4) is circular, the inner ring thereof is connected with the outside of the circumference of the bearing seat (3), and the outer ring is connected with the shell (1); and the left side wall (44) of the cooling device (4) forms the inner wall of a speed reducer oil chamber (5). The speed reducer can lower the temperature thereof in the work process, thus prolonging the service life of each component of the speed reducer. In addition, the invention also discloses a development machine comprising the speed reducer.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to a speed reducer. In addition, the present invention also relates to a boring machine comprising the speed reducer. Background technique [0002] In recent years, with the rapid development of my country's coal industry, the demand for roadheaders is also increasing. In the roadheader, the reducer is an important part and occupies a very important position. [0003] Please refer to figure 1 , figure 1 It is a schematic structural diagram of a typical reducer in the prior art. [0004] The reducer in the prior art includes an input shaft and a housing 1', the outer end 2' of the input shaft is fitted with a bearing, the outside of the bearing is provided with a bearing seat 3', and the outer circumference of the bearing seat 3' is connected with an end cover 4 ', and the end cover 4' is connected to the housing 1' by bolts. Such as figure 1 As shown, there is a certain c...
