Sawing gearbox

Abstract

The invention relates to a sawing gearbox. The sawing gearbox comprises a box body, wherein a working cavity is arranged inside the box body, an input hole used for fixing an input gear shaft is formed in the left end face of the box body, an output hole used for fixing an output gear shaft is formed in the right end face of the box body, the input gear shaft is arranged on the lower portion of the box body, a speed reducer is arranged above the input gear shaft, the output gear shaft is arranged above the speed reducer, and a brake device is arranged above the output gear shaft. The sawing gearbox has the advantages that the sawing accuracy is improved, cost is reduced greatly, the sawing gearbox is applicable to heavy cutting due to the adoption of a spiral gear transmission structure, the accuracy is stable, and the sawing gearbox is reliable, durable, high in overload bearing capacity, low in energy consumption, small in vibration and low in noise.

Description

technical field [0001] The invention relates to the field of sawing machines, in particular to a sawing gear box for heavy cutting. Background technique [0002] At present, there is a gap between the gears in the design and manufacture of the gears in the gear box of the sawing machine. In the subsequent use, the teeth will be deformed with the increase of the use time, so that the gap between the gears will increase, resulting in a gap between the gears. The transmission between them is unstable, the cutting efficiency and cutting accuracy of the saw blade are reduced, and the service life of the gear is reduced. [0003] At present, the motor in the gear box of the saw machine used for heavy-duty cutting is directly connected to the output shaft, so that the ability of the saw blade to cut metal depends entirely on the power of the motor, and the requirements for the motor are very high, which greatly increases the cost. The saw blade needs a lot of torque. When the cutt...

[0002] At present, there is a gap between the gears in the design and manufacture of the gears in the gear box of the sawing machine. In the subsequent use, the teeth will be deformed with the increase of the use time, so that the gap between the gears will increase, resulting in a gap between the gears. The transmission between them is unstable, the cutting efficiency and cutting accuracy of the saw blade are reduced, and the service life of the gear is reduced

[0003] At present, the motor in the gear box of the saw machine used for heavy-duty cutting is directly connected to the output shaft, so that the ability of the saw blade to cut metal depends entirely on the power of the motor, and the requirements for the motor are very high, which greatly increases the cost. The saw blade needs a lot of torque. When the cutting is stopped, the saw blade cannot stop immediately due to the large inertia, and the output bearing bears all the force.
