Automatic anti-backlash cutting gearbox

Abstract

The invention discloses a transmission case for automatically removing a backlash and cutting, which comprises a housing, wherein an input shaft and an output shaft are arranged in parallel inside the housing; the shaft end of the output shaft extends out of the housing and is provided with a saw blade clamp; one end of the input shaft extends out of the housing and is provided with a power input component; the input shaft and the output shaft are in transmission connection via a gear set; a damping shaft is also arranged inside the housing; a damping gear is arranged on the damping shaft; the damping gear is meshed with an output gear arranged on the output shaft, and a pneumatic damper is arranged at the shaft end of the damping shaft. Due to the pneumatic damper, the rotation of the output shaft is properly limited by the damping shaft and the damping gear; a gear gap generated when a work-piece is cut is removed; bounce of the output gear is stopped; the cutting noise is reduced; the cutting precision is improved; the abrasion of the gear is reduced; the cutting is more stable; a notch is smooth, and the device can be applied to various cutting machines and also can be applied to a polishing machine.

Description

technical field [0001] The invention relates to a gearbox, in particular to a gearbox for a cutting machine. Background technique [0002] In the prior art, there are many kinds of structural forms for the gearbox of a cutting machine, which mainly includes an input shaft and an output shaft. The shaft end of the output shaft is provided with a saw blade clamp for holding the saw blade. The input shaft and the output shaft The output shafts are connected through several gear transmissions. When working, the power is input from the input shaft, and the output shaft is driven to rotate through gear transmission, which drives the saw blade to rotate to realize cutting. Its shortcoming is: this type of gearbox in the prior art, there must be a certain gap in the installation process of the gears, and when the reaction force of the workpiece is received, the gears are not always in the meshing state, and the second reaction will occur. Jumping, that is, the gear is affected by ...

Its shortcoming is: this type of gearbox in the prior art, there must be a certain gap in the installation process of the gears, and when the reaction force of the workpiece is received, the gears are not always in the meshing state, and the second reaction will occur. Jumping, that is, the gear is affected by the reaction force, disengages from the meshing state, and meshes again in an instant, resulting in a collision, which not only makes noise, but also leads to increased wear of the tooth surface, uneven incision of the cut workpiece, and poor cutting accuracy
