Reduction gear of vertical type circular sawing machine

Abstract

The invention provides a reduction gear of a vertical type circular sawing machine and relates to the technical field of vertical type circular sawing machines. The reduction gear of the vertical type circular sawing machine is mainly used for solving the problem that the output rotation speed of an exiting vertical type circular sawing machine is high. The reduction gear of the vertical type circular sawing machine comprises a worm wheel and worm pair and two gear pairs. A vertically placed worm is connected with the upper wall and the lower wall of a reduction gearbox through a bearing. A worm wheel matched with the worm is connected with the side wall of the reduction gearbox through a bearing. The worm wheel and the worm form a first-level reduction mechanism. A first gear is coaxially connected with the worm wheel. A second gear meshed with the first gear in a matched mode is connected with the left side wall and the right side wall of the reduction gearbox through a bearing. The first gear and the second gear form a second-level reduction mechanism. A third gear is coaxially connected with the second gear. A fourth gear meshed with the third gear in a matched mode is connected to the side walls of the reduction gearbox through a bearing. The third gear and the fourth gear form a third-level reduction mechanism. The reduction gear is provided with the three levels of reduction mechanisms, so that the rotation speed of a circular saw is appropriate, and the sawing efficiency is improved.

Description

technical field [0001] The invention relates to a vertical circular sawing machine, in particular to a speed reduction device of the vertical circular sawing machine. Background technique [0002] The vertical circular sawing machine is a machine tool that uses a rotating circular saw to saw materials. The rotation of the circular saw needs to be driven by a motor. The output speed of the motor is generally several thousand revolutions per minute, which is too high to be directly used for sawing materials. The output end of the motor needs to be equipped with a deceleration device to achieve the purpose of speed reduction. The deceleration device of the existing vertical circular sawing machine is generally a two-stage reducer, and the speed reduction is realized through two sets of gear pairs. The transmission ratio of standard spur gears is generally i≤5, take the transmission ratio i1=5, i2=4, after two-stage deceleration, the total transmission ratio i'=20, take the inp...
