Description

The small wheel part main shaft driving device of numerical control machine for lapping spiral bevel gear

Technical field

The utility model relates to a kind of bevel gear lapping machine of Gear Processing, especially a kind of small wheel part main shaft driving device of numerical control machine for lapping spiral bevel gear.

Background technology

Numerical control machine for lapping spiral bevel gear is used at a high speed, accurately grinding spiral bevel gear and hypoid bevel wheel, its objective is the heat treated distortion of an amount of corrected gear, improve flank of tooth fineness, improve position, contact zone and size, thereby reach stable drive, reduce noise and improve the ability of carrying.Processing method is that bevel-gear sett is installed on two corresponding main shafts of gear lapping machine, allow two bevel gears keep 0.1-0.15 millimeter sideshake at a high speed to rolling, simultaneously along two gear taperings and the trace shake at a high speed of three directions of offset, applying the 2-50Nm braking moment on the gear wheel main shaft and on two points of mesh, adding the lapping liquid (suspended oil adds corundum) of certain flow and pressure, so grind up to the flank of tooth bleach, till the contact zone reaches requirement.The steamboat work spindle of present known gear lapping machine comes drive shaft to rotate by motor and a pair of belt pulley, motor needs mount pad and belt swelling device, thereby complex structure, floor space are bigger, in addition belt transmission have speed low, skid, flimsy problem, therefore influence operating efficiency.

Summary of the invention

The utility model provides the small wheel part main shaft driving device of a kind of compact conformation, durable, numerical control machine for lapping spiral bevel gear that efficient is high for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of small wheel part main shaft driving device of numerical control machine for lapping spiral bevel gear, by the steamboat casing, be installed in the main shaft that has centre bore in the steamboat casing, be installed in the pull bar that the spindle hole Inner Front End has dish spring and sliding sleeve, the pushing drawing rod sliding sleeve motion that is installed in spindle hole draw-in bar rear end has the push rod of resilient sleeve, be installed in two cylinders of steamboat box back and the piston of the driving pushrod movement that two is connected with putting back-end, and the drive unit that drive shaft is rotated is formed, described drive unit is to be set with the motor that drive shaft is rotated on the main shaft in the steamboat casing, the rotor of this motor is sleeved on the main shaft, the stator of this motor is installed in the steamboat casing by two ring flanges, and the motor stator outer surface also is set with cooling jacket; Described main shaft is forward and backward two sections and is formed by connecting that its joint face liner has heat insulation insulation board every magnetic, and the rear end of back segment main shaft also is equipped with the encoder of flange cover and speed feedback.

Advantage and the good effect that the utlity model has are: be sleeved on motor on the main shaft because rotor is installed in the steamboat casing, the motor direct-drive main shaft is rotated, removed belt drive unit, simplify the structure greatly, improved whole spindle drive performance, made that spindle operation is steady, precision is high, rigidity is strong, open that only the time is short, efficient is high.The utility model also has compact conformation in addition, moment of torsion is big, noise is low, the advantage of long service life.
