Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Automatically the condition requiring bevel gear inspecting machine to possess tooth method of the present invention: drive X linear motion axis and Z linear motion axis that bevel pinion and bevel gear wheel move along respective axis；Drive A rotating shaft and C rotating shaft that bevel pinion and gear wheel rotate along respective axis；And control system.
As shown in the figure, the frame for movement of 4 universal driving shafts of bevel gear inspecting machine: X-axis linear electric motors (1) provide the power of X-axis rectilinear motion, drives slide unit (6) and electro spindle (5) along guide rail (2) along the positive and negative rectilinear motion of X-axis by leading screw (3).Bevel pinion (7) clamping, on electro spindle (5), is moved linearly together with electro spindle (5).Electro spindle (5) internally installed electric rotating machine, and A axle rotary motion power is provided, drive bevel pinion (7) both forward and reverse directions to rotate.Grating scale (4) is parallel with guide rail (2), positions and feed back position and the displacement of bevel pinion (7).Z axis linear electric motors (8) provide the power of Z axis rectilinear motion, drive slide unit (13) and electro spindle (12) along guide rail (9) along the positive and negative rectilinear motion of Z axis by leading screw (10).Bevel pinion (14) clamping, on electro spindle (12), is moved linearly together with electro spindle (12).Electro spindle (12) internally installed electric rotating machine, and C axle rotary motion power is provided, drive bevel pinion (14) both forward and reverse directions to rotate.Grating scale (11) is parallel with guide rail (9), positions and feed back position and the displacement of bevel gear wheel.Electric current internal for this X linear axis servomotor (1) and Z linear axis servomotor (8) and output torque meet fixing functional relationship, such that it is able to calculate the moment born according to the galvanometer in motor, and then calculate the power suffered by bevel gear.The Circular gratings installed on this A axle electro spindle (5) and C axle electro spindle (12) front end face can measure rotational angle and the velocity of rotation of bevel gear.
As it can be seen, utilize above-mentioned bevel gear testing machine method to tooth automatically, mainly comprise the steps that
Automatically working to before tooth: first input the parameter information of bevel gear to be engaged, parameter information at least to include the theoretical locating distance of two bevel gears, circular tooth thickness.X/Z axle is respectively mounted little, bevel gear wheel, and passes through clamp.
Automatically tooth being worked: the information according to bevel gear wheel (14), bevel gear wheel (14) is delivered to the theoretical position of engagement by the linear axis servomotor (8) of Z axis, and and is fixed.Bevel gear wheel (14) maintains static in the Z-axis direction, and bevel pinion (7) is close to bevel gear wheel with certain speed from afar.It is the position of 4mm-6mm that bevel pinion (7) is fed into distance bevel gear wheel (14) tooth top, enters region to be engaged, then proceeds by the tooth stage.
When bevel gear entered the tooth stage, under the driving of linear axis servomotor (1), bevel pinion (7) is close to bevel gear wheel (14) at a slow speed, the A axle rotational restraint of fixing bevel pinion (7), loosens the C axle rotational restraint of bevel gear wheel (14)；Simultaneously, the positional information of grating scale (4) feedback bevel pinion (7) is to control system, the rotation information of Circular gratings feedback bevel gear wheel is to control system, and the Resistance Value of linear axis servomotor (1) feedback bevel gear is to control system.
To the tooth stage, the way of contact of two bevel gears has two kinds, and one is peak contact, i.e. non-engagement state；Another kind is flank contact, i.e. engagement.By the size of current information of the positional information of bevel pinion (7), the rotation information of bevel gear wheel (14) and servomotor (1), control system judges whether bevel gear is in engagement peak contact or flank contact.After two bevel gear contacts, bevel pinion (7) is subject to contact resistance, and pass to linear axis servomotor (1) with the form of moment by leading screw (3), linear axis servomotor (1) improves motor output torque by changing internal current, and by current feedback to control system, the contact resistance of reflection bevel pinion.Grating scale (4) reads the positional information of bevel pinion (7), and Circular gratings reads the rotation information of bevel gear wheel (14), feeds back to control system.Being fed back by these signals, control system can be determined that whether two bevel gears enter engagement.
Along with bevel pinion (7) is mobile to bevel gear wheel (14) with the 3%-5% of X-axis full speed, control system reads feedback information, when the tooth top of bevel pinion (7) crosses the tooth top position of bevel gear wheel, and continue close to bevel gear wheel (14), Resistance Value f suffered by bevel pinion (7) is not above the Resistance Value F of regulation, the resistance f of bevel pinion promotes bevel gear wheel to rotate certain angle, to adapt to the gear position of bevel pinion, this situation is flank contact condition engagement.When two bevel gears are in bevel gear engagement, bevel pinion (7) continues to move along, and drives bevel gear wheel to turn an angle and arrives the theoretical position of engagement.When bevel pinion (7) invariant position or change are ignored, and the tooth top distance of little bevel gear wheel is close to 0, and the resistance f suffered by bevel pinion (7) sharply increases, and exceedes the Resistance Value F of regulation, and bevel gear wheel does not rotate with resistance.Regulation Resistance Value F:
F≈1.25×(fx+μMy/P1)
Wherein: fxThe frictional resistance of X guide rail；
μ stiction coefficient；
MyThe moment of friction of bevel gear wheel；
P1The locating distance of bevel pinion.
This situation is peak contact state non-engagement state.When two bevel gears are in non-engagement state, X-axis falls back 3mm, then rotates α degree angle,
Then proceed to restart to perform above-mentioned to tooth step, until two bevel gears complete to enter engagement in 5 times.If 5 times still cannot be introduced into engagement, then exited by X/Z axle, check two bevel gear gears and the gear information of input.If these information do not have mistake, be repeated said process.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention, can be practiced according to the content of description.
