Description
Technical field
The present invention relates to a kind of non-integral Rotary bisections to saw.
Background technology
Rotary bisection saw is the concentric output shafts by driving transmission device, while driving outer saw blade and interior saw blade, one
It moves in the direction of the clock, one rotates counterclockwise, to the opposite direction rotating cutting movement generated.Due to outer saw blade and
The sawing direction of interior saw blade is on the contrary, when outer saw blade and interior saw blade can mutually balance cutting, the reaction force of cut material material is realized
Steady quickly cut-out.
Under prior art conditions, the transmission device of non-integral Rotary bisection saw blade, due to interior saw blade compressing structure
Limitation, manufactured Rotary bisection saw blade both at home and abroad, using wear ring or resistance to is arranged on the working face of interior saw blade and outer saw blade
Grind axially position of the mode of boss as interior saw blade.In saw blade during running at high speed, including wear ring or wear-resisting boss
Rub rotation between saw blade and outer saw blade, causes drag ring or friction boss friction fever, the abrasion of wear ring or boss, and meeting
Cause interior saw blade to cannot get reliable location, interior saw blade and outer saw blade is made to loosen, saw blade interior in this way and outer saw blade more cannot be reliable
Positioning and compression, in addition foozle, generate rotary jumping and swing inevitable, consequence is to lead to outer saw blade and interior saw
When piece rotates in opposite directions, frictional heat, interference and collision between saw blade, meanwhile, also will produce cut material material outer saw blade and interior saw blade it
Between heap it is stifled, cause broken teeth even to cause the adverse consequences such as personal safety danger.
The transmission device of integrated form Rotary bisection saw blade, though the outer saw blade of outer saw blade component and the interior saw of interior saw blade can be eliminated
The problem of piece component pivoting friction, outer saw blade and interior saw blade cutter tooth collide；Improve the use of the impact strength and saw blade of cutter tooth
Service life, but due to being integrated form, when replacing saw blade, package unit has to give up, and causes largely to be integrated in saw blade component
On non-saw blade material waste and manufacturing cost increase, due also in the cooperation of existing ratchet, due to need to compensate wear ring or
When the abrasion of wear-resisting boss, it has to leave a certain amount of axial gap between ratchet, when machine startup, will produce and touch between ratchet
Abnormal sound and vibration is hit to open machine moment, cutting material easily makes saw blade point when saw blade contacts cutting material before machine startup
Fork.
