Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bevel gear machining technique, specifically tooth groove cutting device for spiral bevel gear machining. BACKGROUND

[0002] Among various mechanical transmissions, the transmission efficiency of spiral bevel gears is the highest, which has great economic benefits for various transmissions, especially high-power transmissions; the transmission pair of transmission components needed for transmitting the same torque is the most space-saving, smaller than the space size needed by belt and chain transmission; the transmission ratio of spiral bevel gears is permanently stable, which is often the basic requirement for transmission performance in various mechanical equipment transmissions; spiral bevel gears are reliable in operation and long in service life.

[0003] The existing spiral bevel gear grinding machine can be referred to the Chinese utility model patent with the announcement number CN211073017U, which discloses a spiral bevel gear grinding machine, comprising a base plate, two support plates fixedly installed on the top of the base plate, a top plate fixedly installed on the top of the support plate, a water tank fixedly installed on the right side of the base plate, and a small base fixedly installed on the middle of the top of the base plate. A motor is fixedly installed on the middle of the small base, and a rotating shaft is fixedly installed on the top of the motor. The spiral bevel gear grinding machine concentrates two polishers in one program through the multiple hydraulic rods. In the past, spiral bevel gear polishing needs to go through three steps of polishing, which is troublesome. Now, the device can further reduce the polishing steps. The motor drives the spiral bevel gear to rotate and the polisher to polish, while the primary polisher and the secondary polisher are stationary. They only need to adjust the position up and down under the driving of the multiple hydraulic rods, which greatly improves the working efficiency of the machine.

[0004] When cutting the gear, the bevel gear needs to be kept in an inclined state to keep the generatrix of the bevel gear horizontal for cutting. When cutting different models of bevel gears, the inclination angle of the base needs to be adjusted manually to keep the generatrix of the bevel gear horizontal, which is very inconvenient. Before processing, the diameter of the tool rotation path needs to be adjusted according to the demand to adjust the helix angle of the gear groove, and the existing cutting device is very inconvenient to adjust.
