Abstract
The utility model relates to a large-torque groove cutting machine which comprises a housing, a motor, a gear case front cover, a gear case rear cover and an output shaft, wherein the motor is arranged in the space between the gear case rear cover and the housing, the gear case front cover and the gear case rear cover are fixedly connected with each other, and the motor and the output shaft are connected through a gear assembly. The large-torque groove cutting machine is characterized in that the gear assembly comprises a driving gear, a driven gear, a pinion wheel coaxial to the driven gear and an output shaft gear; the driving gear is arranged on the transmission shaft of the motor; the driven gear and the pinion wheel are fixed inside the gear case front cover; the driving gear is meshed with the driven gear; the driven gear is meshed with the pinion wheel; the pinion wheel is meshed with the output shaft gear; and the output shaft gear drives the output shaft to rotate. The large-torque groove cutting machine effectively increases the cutting capacity of the cutting machine and prolongs the service life of the cutting machine.
Description
Technical field
The utility model relates to a kind of cutting machine, relates in particular to a kind of large-torsion notching cutter.
Background technology
Present cutting machine is owing to adopt the one-level speed change, and torsion is little, and cutting is slow and cutting power is low, also may be because electric current is excessive or voltage instability causes motor to damage.Present cutting machine is bearing under the pressure of 30Kg, and rotating speed obviously descends, and forms load operation, has a strong impact on the service life of motor.Therefore, cutting power and the motor that how to improve cutting machine becomes urgent problem service life.
The utility model content
The purpose of this utility model provides a kind of large-torsion notching cutter, can effectively improve the cutting power of cutting machine, prolongs the service life of cutting machine.
The technical solution adopted in the utility model is:
Large-torsion notching cutter, comprise casing, motor, the gear-box protecgulum, gear-box bonnet and output shaft, described motor is located in the space between gear-box bonnet and the casing, described gear-box protecgulum is fixedlyed connected with the gear-box bonnet, described motor is connected by gear train with output shaft, described gear train comprises driving gear, driven gear, pinion and the output shaft gear coaxial with driven gear, described driving gear is located on the motor transmission shaft, described driven gear and pinion are fixed in the gear-box protecgulum, described driving gear and driven gear engagement, described driven gear and pinion, described pinion and output shaft gear engagement, described output shaft gear drives output shaft and rotates.
The utility model has increased driven gear and the pinion coaxial with driven gear, change original one-level speed change into two stage speed change, it is the engagement of driving gear and driven gear, driven gear and pinion, pinion and output shaft gear engagement, output shaft gear drives output shaft and rotates, can strengthen the holding capacity of load like this, under the pressure of 30Kg, still equate with no-load speed, the cutting speed and the ability of gear have been improved greatly, and avoided the generation motor load excessive and damage motor, prolonged motor service life.
