Speed reducer box

Abstract

The invention discloses a speed reducer box. The speed reducer box comprises a box cover and a box body; the box body and the box cover are integrally formed and are provided with a plurality of bearing installing holes; and on the bottom wall of the box body, the edges of the front end and the rear end of one side are oppositely provided with fixing and installing holes A of ground feet, and machining stations of to-be-machined fixing and installing holes B matched with actual installing holes of different bases are reserved on the edges of the front end and the rear end of the other side. According to the speed reducer box, the installing positions of the ground feet are adjustable, machining is easy, the machining precision is high, the assembly precision of bearings and other parts is high, the torsion-resistant capacity is high, and the running stability of a speed reducer is good.

Description

technical field [0001] The invention relates to a reducer casing for a direct air cooling fan. Background technique [0002] With the rapid development of the national economy, the improvement of people's lives and the increase of emerging enterprises, the demand for electricity is increasing year by year. In order to meet the needs of people's life and enterprise production for electricity, it is necessary to expand or build new large-scale power plants. At present, my country mainly uses thermal power generation, and the cooling system is mainly based on direct air-cooling systems, and the demand for direct air-cooling fans is large. [0003] Such as figure 1 and figure 2 As shown, the box cover 1 and the box body 2 of the existing direct air-cooled fan reducer box are split structures, which are fixed together by bolts. The processing flow of the joint surface of the box body 2 and the box cover 1 is complicated. After the box cover 2 is assembled, the bearing hole lo...

Problems solved by technology

[0003] like figure 1 and figure 2 As shown, the box cover 1 and the box body 2 of the existing direct air-cooled fan reducer box are split structures, which are fixed together by bolts. The processing flow of the joint surface of the box body 2 and the box cover 1 is complicated. After the box cover 2 is assembled, the bearing hole located at the junction of the box body and the box cover is reprocessed. The process is cumbersome, the box body has large stress and deformation due to processing, the machining accuracy is poor, and the assembly accuracy of other parts such as bearings is low; the box body Poor torsion resistance, poor running stability

In addition, the setting position of the foot 3 of the reducer box is fixed, and the base for installing the reducer box in the direct air-cooled fan equipment must be installed correspondingly to narrow the application range; When using a new reducer, because the feet of the new reducer box do not match the original base installation position, the base that matches the feet of the new reducer box must be redesigned, which will result in a long renovation period and high cost
