At the shortcoming of prior art, the purpose of this utility model provides a kind of energy simple and easy switching band saw cutting speed and improves the transmission device of the band sawing machine of cutting efficiency greatly.
For achieving the above object, the technical solution of the utility model is: a kind of transmission device of band sawing machine, comprise that the band saw wheel reaches band saw wheel down, upper and lower band saw wheel connects by belt transmission, following band saw wheel is connected with main motor, also be provided with variable-speed motor between following band saw wheel and the main motor, the inputting shaft of variable-speed motor and the output shaft of main motor are in transmission connection, and force-output shaft is in transmission connection with following band saw wheel.
Between the output shaft of described main motor and the inputting shaft of variable-speed motor, between the turning cylinder of the force-output shaft of variable-speed motor and following band saw wheel by belt pulley and feed belt transmission or by the chain-drive mechanism transmission or by gear drive.
The inputting shaft of variable-speed motor is provided with master gear, force-output shaft is provided with different change-speed gearings, and master gear and change-speed gearing are in transmission connection by gear transmission chain.
This transmission device also comprises a gear lever and connected shift fork, and shift fork is connected with gear transmission chain by sliding sleeve.
Compared with prior art, the utility model is provided with variable-speed motor and transmission mechanism thereof in transmission device, make the workpiece that band saw when cutting can corresponding unlike material select different cutting speeds, and only need stir the cutting speed that gear lever can switch band saw easily, but improve cutting efficiency greatly and strengthened the kind of cut workpiece.
Description of drawings
Fig. 1 is the structural representation of the transmission device of the utility model band sawing machine.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, the band sawing machine that the utility model transmission device is installed is made up of support 1, fuselage 2 and head 3 three parts.Wherein, support 1 is positioned at the bottom, and fuselage 2 forms one from the extension of support 1 one side direction and with head 3; The main motor 4 rotating band saw wheels that are positioned on the support 1 rotate, and upper and lower band saw wheel is wound with the band saw that forms closed circulation; The workbench of when on the support 1 and in fuselage 2 the place aheads the sawing workpiece being installed also, using 5.
The transmission device of band sawing machine of the present utility model, comprise that the band saw wheel reaches band saw wheel down, upper and lower band saw wheel connects by belt transmission, following band saw wheel is connected with main motor 4, also be provided with variable-speed motor 9 between following band saw wheel and the main motor 4, the output shaft of the inputting shaft of variable-speed motor 9 and main motor 4 is in transmission connection, and force-output shaft is in transmission connection with following band saw wheel.
Between the inputting shaft of the output shaft of described main motor 4 and variable-speed motor 9, between the turning cylinder of the force-output shaft of variable-speed motor 9 and following band saw wheel by belt pulley and feed belt transmission.Between the inputting shaft of the output shaft of certain main motor 4 and variable-speed motor 9, also can be between the turning cylinder 7 of the force-output shaft of variable-speed motor 9 and following band saw wheel by the chain-drive mechanism transmission or by gear drive.The belt pulley that adopts in the present embodiment and the transmission mechanism of feed belt, making variable-speed motor 9 to walk abreast with main motor 4 arranges, make that the layout of variable-speed motor 9 is more reasonable, and the quality of belt pulley and following band saw wheel is approaching, utilizes belt pulley to come the turning cylinder 7 of band saw wheel under the transmission can make that the rotation of band saw wheel is more stable down.
The inputting shaft of variable-speed motor 9 is provided with master gear, force-output shaft is provided with different change-speed gearings, and master gear and change-speed gearing are in transmission connection by gear transmission chain.
This transmission device also comprises a gear lever 8 and connected shift fork, and shift fork is connected with gear transmission chain by sliding sleeve.When needing the rotating speed of conversion variable-speed motor 9 force-output shafts, only need control gear lever 8, by shift fork and sliding sleeve change gear driving-chain master gear is connected on the different change-speed gearings, thereby realizes gearshift.
During this band sawing machine running, main motor 4 provides power, by the be in transmission connection belt pulley of variable-speed motor 9 inputting shafts of driving belt, drive inputting shaft, again by the gear graduation in the variable-speed motor 9, the force-output shaft of variable-speed motor 9 drives turning cylinder 7 by driving belt and belt pulley again and rotates, thereby driving down, the band saw wheel rotates, belt pulley is fixed on the same axle with following band saw wheel, under the drive of turning cylinder 7, following band saw wheel is done equidirectional with belt pulley, with the operation of rotating speed, rotate by band saw wheel in the driving belt transmission by following band saw wheel at last, thus the cutting movement of realization band saw.
