Abstract
The utility model relates to a transmission clearance removing mechanism which comprises a driving shaft, a variable speed shaft, an output shaft, a driving gear, a variable speed large gear, a variable speed pinion and an output gear. The driving gear is arranged on the driving shaft, the variable speed large gear and the variable speed pinion are respectively arranged on the variable speed shaft, the output gear is arranged on the output shaft, the driving gear is meshed with the variable speed large gear, and the output gear is meshed with the variable pinion. The transmission clearance removing mechanism further comprises a brake shaft, a brake gear and an electromagnetic type brake, a brake gear is arranged on the brake shaft, the brake gear is meshed with the variable speed large gear, and the shaft end of the brake shaft is connected with the electromagnetic type brake. The transmission clearance removing mechanism has the advantages that the mechanism is compact and reasonable in structure, brake time and brake torque can be practically controlled through the electromagnetic type brake, and the transmission clearance from the driving shaft to the output shaft is removed through the brake torque, so that reverse vibration produced when a saw web conducts sawing and cutting is reduced.
Description
Technical field
The utility model relates to a kind of circular sawing machine, particularly a kind of drive gap eliminating machine.
Background technique
Saw blade driving mechanism of the prior art, comprise driving shaft, variable-speed shaft, output shaft, driving gear, speed change gearwheel, change speed pinion, output gear, driving gear is installed on driving shaft, on variable-speed shaft, be separately installed with speed change gearwheel, change speed pinion, output gear is installed on output shaft, driving gear and the engagement of speed change gearwheel, output gear and change speed pinion engagement, described saw blade and output shaft are in transmission connection.Its deficiency is: between from driving shaft to output shaft, have drive gap, the reverse vibrations that can produce when sawing; And when saw blade rigidly connects tactile workpiece, the impulsive torque producing while increasing heavy duty suddenly by zero load affects whole power system, thereby has reduced the working life of gear and each transmission shaft.
Summary of the invention
The purpose of this utility model is exactly for fear of the deficiency in background technique, and a kind of drive gap eliminating machine is provided.
For achieving the above object, the utility model adopts following technological scheme: a kind of drive gap eliminating machine, comprise driving shaft, variable-speed shaft, output shaft, driving gear, speed change gearwheel, change speed pinion, output gear, driving gear is installed on driving shaft, on variable-speed shaft, be separately installed with speed change gearwheel, change speed pinion, output gear is installed on output shaft, driving gear and the engagement of speed change gearwheel, output gear and change speed pinion engagement, described drive gap eliminating machine also comprises brake axle, spragging gear and electromagnetic brake, spragging gear is installed on brake axle, this spragging gear and the engagement of speed change gearwheel, the axle head of brake axle is connected with electromagnetic brake.
For a kind of optimization of the present utility model, driving shaft, variable-speed shaft and brake axle two ends axle head are respectively equipped with the bearing being connected with gear-box.
For a kind of optimization of the present utility model, driving gear, speed change gearwheel, change speed pinion, output gear and spragging gear are helical gear.
The utility model is compared with background technique, having one is compact structure, reasonable, electromagnetic brake can be according to working control period of braking and braking torque, by braking torque, eliminate the drive gap from driving shaft to output shaft, thereby reduced the reverse vibrations that saw blade can produce when sawing; The 2nd, when saw blade does not start sawing, can apply moment of torsion to main shaft, and when saw blade starts to contact workpiece releasing brake moment of torsion; The 3rd, analog main shaft is always all at load condition, in order to avoid when saw blade rigidly connects tactile workpiece, the impulsive torque producing while increasing heavy duty suddenly by zero load affects whole power system.The 4th, effectively eliminated the drive gap in Transmitted chains and can guarantee outputting power stably, thereby greatly having improved the working life of gear and main shaft, and working life of having improved saw blade; The 5th, power output mode can also improve the surface finishment of workpiece stably.
