The utility model is characterized in that a mainshaft loading motor is installed inside a large wheel box; the central hole of the rotor of the motor is jacketed on the mainshaft; a cooling water sleeve is jacketed out of the stator of the motor; the mainshaft consists of a front mainshaft, a middle mainshaft and a back mainshaft; the front mainshaft is connected with the middle mainshaft by three elastic rods; a heat-insulation and magnetism insulation plate is padded on the connecting plane between the middle mainshaft and the back mainshaft; a pull rod and its disc spring for loading and unloading the workpieces is installed inside the central hole of the middle mainshaft; a push rod and an elastic jacket are installed inside the central hole of the back mainshaft; a cylinder driving the push rod to motion is installed at the back end of the push rod; a flange jacket and a coder are installed at the back end of the back mainshaft. The utility model removes the belt transmission loading device, makes the motor directly function on the mainshaft for loading, and largely simplifies the structure. What is more, the utility model has the advantages of dense structure, high running precision, large torsion, low noise and long service life.
Description
Technical field
The utility model relates to a kind of bevel gear lapping machine of Gear Processing, especially a kind of bull wheel work spindle transmission 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, on the gear wheel main shaft, apply the 2-50Nm braking moment, and on two points of mesh, add 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 bull wheel main shaft of present known gear lapping machine is to drive a hydraulic motor by a pair of belt by hydraulic system the bull wheel main shaft to be loaded.Control the oil liquid pressure of hydraulic motor by the electro-hydraulic proportional valve of setting loading system oil pump, regulating system, reach loading purposes.Because this device is belt transmission, thereby load under the effect of countertorque in gear lapping processing, the bull wheel main shaft phenomenon that throws switch, countertorque is very inaccurate yet, influences crudy, and belt transmission also has low, fragile, the inefficient problem of rotating speed in addition.
Summary of the invention
The utility model provides a kind of bull wheel work spindle transmission device of simple in structure, 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 bull wheel work spindle transmission device of numerical control machine for lapping spiral bevel gear, by the bull wheel casing, be installed in the main shaft that has centre bore in the bull wheel casing, be installed in the pull bar and the dish spring thereof of spindle hole Inner Front End, be installed in the push rod of spindle hole draw-in bar rear end pushing drawing rod motion, be sleeved on the resilient sleeve on the push rod, be installed in two cylinders of bull wheel 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 bull wheel casing, the rotor bore of this motor is sleeved on the main shaft, the stator of this motor is installed in the bull wheel casing by two ring flanges, and the motor stator outer surface also is set with cooling jacket; Described main shaft is forward spindle, middle main shaft, afterwards main shaft is formed by connecting, the uniform elastic rod that three transmitting torques are installed between forward spindle and the middle main shaft joint face, liner has heat insulation insulation board every magnetic on the joint face of middle main shaft and back main shaft, and the rear end of back 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 the motor on the main shaft and be installed in speed feedback encoder on the main shaft because rotor is installed in the bull wheel casing, by electrical control motor is directly loaded to main shaft, belt drive unit and hydraulic system have been removed, 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.
