description The invention relates to a cutting speed reducer for a coal mine development machine, comprising a case, an input shaft and a planetary deceleration assembly connected with the input shaft. The cutting speed reducer is characterized in that the case of the cutting speed reducer is a cylinder respectively provided with an input end flange and an output end flange at both ends and a partition board. The invention simplifies the case structure that can be in cast form, thereby improving the integrated intensity of the case, avoiding the problem of weld stress convergence existing in a welded structure, realizing optimum transmission load balancing, improving the transmission efficiency and guaranteeing processing and installation accuracy; therefore, the internal structure of the whole speed reducer is simple, practical and compact. A needle bearing is selected and used on a low speed level planetary wheel, thereby being capable of meeting the requirement for structure configuration and the requirements for work
