Summary of the invention
For solving the problems referred to above, the utility model proposes a kind of gear-hobbing machine.
A kind of gear-hobbing machine, it includes the first motor, the speed gears being connected with the first motor-driven, the worm gear pair being in transmission connection with speed gears, the pawl wheel engaged with worm gear pair, the master gear coaxially connected with pawl wheel, it is arranged on the finger cutter directly over master gear, drive the second motor that finger cutter rotates, cam, the first roller closed with cam meshing, the spring being connected with the first roller, up and down motion bar, it is arranged on the knife rest on up and down motion bar, the second roller being connected with cam coaxial, the spline shaft being meshed with the second roller, the 3rd roller being meshed with spline shaft, the divided teeth gear coaxially connected with the 3rd roller, the 4th roller being meshed with divided teeth gear；Wherein, described 4th roller is coaxially connected with worm gear pair.
Gear-hobbing machine described in gear-hobbing machine of the present utility model includes screw mandrel；Described screw mandrel is arranged on immediately below knife rest.
Described in gear-hobbing machine of the present utility model, gear-hobbing machine also includes the 5th roller；The motor shaft of described 5th roller and the first motor is coaxially connected and mentions with speed and is meshed.
Gear hobbing described in gear-hobbing machine of the present utility model, rotates finger cutter under cam, the first roller, spring and up and down motion bar act on jointly and pumps relative to knife rest；Master gear rotates under the first motor, speed gears and worm gear pair drive；When finger cutter up and down motion speed is identical with master gear reference circle tangential motion linear velocity, its compound motion track is the straight line of inclination 45 °, changes cam curve parameter and can obtain straight line and the curve of different angle；The cam finger cutter that rotates a circle once moves back and forth；Divided teeth gear makes finger cutter up and down reciprocatingly number of times consistent with the added work gear number of teeth；Adjusting processed gear tangential position makes revolution mark meet drawing requirement.Finger cutter uses the first motor, and rotating speed is 2850r/min, and stock-removing efficiency is high, and machined surface roughness is low；By leading screw, knife rest is moved up and down the vertical dimension of adjustable finger cutter and master gear end face, to change the cutting depth of vertical direction.
