Main shaft transmission arrangement structure of vertical lathe

Abstract

The invention discloses a main shaft transmission arrangement structure of a vertical lathe. The main shaft transmission arrangement structure comprises a motor, a reduction gearbox, a main shaft anda transmission gear ring, wherein the motor is mounted through a motor mounting plate; a motor shaft of the motor faces downwards; a reduction gearbox mounting groove is formed in a lathe body; an input shaft and an output shaft of the reduction gearbox face upwards and are directly opposite to the motor shaft; the input shaft of the reduction gearbox is in transmission connection with the motor shaft through a belt wheel and a belt; the main shaft is mounted in the transmission gear ring through a bearing support; a gear is arranged on the output shaft of the reduction gearbox in a sleeving manner; and the peripheral part of the transmission gear ring is meshed with the gear. According to the main shaft transmission arrangement structure, the motor shaft is mounted in an inverted manner,and a mounting space for mounting a transmission mechanism and the reduction gearbox is formed in the lathe body, so that the mounting space of a mounting part of the vertical lathe is greatly reduced, the structure is relatively compact, and the transmission efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of vertical lathe main shaft transmission, and particularly relates to an arrangement structure suitable for vertical lathe main shaft transmission. Background technique [0002] As the core part of the machine tool, the spindle's rotation accuracy will directly affect the roundness, cylindricity, runout and other accuracy of the processed parts. [0003] At present, the traditional arrangement of spindle drive: the installation position of the main motor is separated from the bed, and the power is transmitted through a long V-belt. In addition, the spindle positioning support structure is composed of double-row cylindrical roller bearings + thrust ball bearings, of which the double-row cylindrical roller bearings are the main support; the thrust cylindrical roller bearings mainly carry the weight of the workpiece and load it on the worktable during the cutting process cutting force. This type of spindle d...
