[0002] The gear shaft of the traditional vertical shaft reducer is mostly installed with a step reserved on the box, and the gear shaft is supported by the bearing through the step. However, because the gear shaft gear in the reducer needs to be adjusted during the meshing installation, there is adjustment in the vertical direction. The precision is poor, and the step reserved on the box cannot meet the adjustment of poor precision, which affects the gear meshing performance; in addition, the bottom of the vertical reducer box is equipped with a lubricating oil discharge port, but due to the granular impurities in the lubricating oil, impurities Easy to enter the support bearing at the bottom with lubricating oil, affecting the service life of the bearing

Embodiment Construction
[0010] Further description will be given below in conjunction with the accompanying drawings and embodiments.
[0011] figure 1 Middle: A hanging sleeve vertical gear shaft chip block lubricating reducer comprises a box body 1, an input bevel gear shaft 2, a bevel gear 3, a vertical gear shaft 4, a bearing sleeve 5, a double row spherical roller bearing 7, Cover 8, chip retaining ring 9. The input bevel gear shaft 2 drives the bevel gear 3 placed on the vertical gear shaft 4 in the box 1. The upper end of the vertical gear shaft 4 is supported on the step in the bearing sleeve 5 through the double row spherical roller bearing 7. The bearing sleeve 5. The upper end is supported on the box body through the flange edge and is sealed by the stuffing cover 8 through the bolts; the lower end of the vertical gear shaft 4 is supported in the supporting hole 10 of the box body through the double row spherical roller bearing, and the box above the supporting hole is supported. A chip ...

The invention relates to a chip blocking lubricating speed reducer with a vertical gear shaft hung on a sleeve. The chip blocking lubricating speed reducer comprises a box body, an input bevel gear shaft, a bevel gear and a vertical gear shaft, wherein the input bevel gear shaft is in transmission connection with the bevel gear arranged on the vertical gear shaft in the box body, the upper end ofthe vertical gear shaft is supported on a step in the bearing sleeve through a bearing, and the upper end of the bearing sleeve is supported on the box body through a flange edge and is sealed by penetrating bolts through a blank cap; and the lower end of the vertical gear shaft is supported in a supporting hole of the box body through the bearing, a circle of chip blocking ring is arranged at thebottom of the box body above the supporting hole, and the inner diameter of the chip blocking ring is larger than the pore diameter of the supporting hole. The chip blocking lubricating speed reducerhas the advantages that the structure is simple and compact, requirements for mounting and adjusting accuracy of the vertical gear shaft are met, the gear shaft is connected in a supported and hung mode, and lubricating impurities are prevented from damaging the bearing.
Description
technical field [0001] The invention relates to a reducer, in particular to a hanging sleeve vertical gear shaft chip-blocking lubricating reducer. Background technique [0002] The pinion installation of the traditional vertical shaft reducer mostly adopts the reserved spigot step on the box, and the pinion is supported by the bearing through the step. However, since the inner pinion gear of the reducer needs to be adjusted during meshing installation, there is adjustment in the vertical direction. The accuracy is poor, and the reserved spigot steps on the box cannot meet the adjustment of poor accuracy, which affects the gear meshing performance; in addition, the bottom of the vertical reducer box is provided with a lubricating oil discharge port, but due to the granular impurities in the lubricating oil, impurities It is easy to enter the support bearing at the bottom with the lubricating oil, which affects the service life of the bearing.
