The alignment method disclosed by the invention mainly aims to realize the grinding of an outer-ring race surface on a floor type grinding machine, and then aims to indirectly meet the accuracy requirement for the difference in the wall thickness of an outer-ring small end face, thereby improving the grinding efficiency of the outer ring on the floor type grinding machine.
Description
Technical field
The invention belongs to the bearing grinding technical field, specially refer to a kind of steep-angle bearing outer ring is realized grinding at floor grinding machine aligning method.
Background technology
Steel-angle bearing generally is used in only has axial load or axial load greater than the workplace of radial load.Because the angle of the relative outer ring of the roller surface central axis of steep-angle bearing outer ring is larger, exceeded the angle grinding scope of electric magnetic no-core grinding machine, so can not realize at the electric magnetic no-core grinding machine grinding of outer ring raceway face.
The roller surface grinding of steep-angle bearing outer ring can realize that at floor grinding machine floor grinding machine is the professional grinding machine that Lip river axle, watt axle equipment company produce.
In conjunction with Fig. 1, the aligning method of floor grinding machine when grinding steep-angle bearing outer ring roller surface is as follows:
After outer ring periphery D grinding is finished, measure first the Wall-Thickness Difference of outer ring raceway face B and outer ring periphery D with instrument, the little value point of the large value point of described Wall-Thickness Difference and described Wall-Thickness Difference is labeled in respectively on the small end face C of outer ring, during centering table is beaten on the roller surface B of outer ring, the grinding of its roller surface B is carried out in fastening outer ring behind the large value point of the described Wall-Thickness Difference of centering and the little value point of described Wall-Thickness Difference.
The weak point of above-mentioned centering is:
1, the measurement of outer ring raceway face B and outer ring periphery D Wall-Thickness Difference requires accuracy higher, is prone to the human error phenomenon;
If 2, occur again centering clamping of the loosening phenomenon needs in outer ring in the grinding process, also need remeasure the Wall-Thickness Difference of outer ring raceway face B and outer ring periphery D, increase man-hour, efficient is very low.
Summary of the invention
For addressing the above problem, the invention provides a kind of steep-angle bearing outer ring and realize the aligning method of grinding at floor grinding machine, this aligning method is to process first the basic circle cambered surface, realize the centering of outer ring on floor grinding machine by the basic circle cambered surface, aligning method is simple and practical, has improved the grinding efficiency of outer ring on floor grinding machine.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of steep-angle bearing outer ring is realized the aligning method of grinding at floor grinding machine, the large cone angle of the relative outer ring of outer ring raceway face central axis is the ɑ degree, described large cone angle makes the outer ring both ends of the surface produce outer ring large end face and outer ring small end face, and aligning method of the present invention comprises following content:
I, elder generation's grinding on the electric magnetic no-core grinding machine go out the basic circle cambered surface of outer ring roller surface and large end face junction, outer ring, and the axial width of described basic circle cambered surface is controlled in 3 mm, and the bus of the bus of described basic circle cambered surface and outer ring periphery is parallel to each other;
II, if the large cone angle of the relative outer ring of outer ring raceway face central axis is the ɑ degree, then the chuck with floor grinding machine also is inclined to the ɑ degree, the outer ring large end face is abutted against on the pillar of floor grinding machine chuck configuration and by the tentatively fixing outer ring of pressing plate, inhale magnetic power meter in the end of floor grinding machine grinding wheel spindle and make the contact pilotage of magnetic power meter point to described basic circle cambered surface, low speed rotation chuck and tapped outer ring make the magnetic power meter indicator be in the minimum wobble state, the oscillating quantity of magnetic power meter indicator is less to represent that then the rotation of chuck is just more parallel with the bus of described basic circle cambered surface, is under the minimum wobble state clam member at the magnetic power meter indicator and makes that the outer ring is fixing namely finishes steep-angle bearing outer ring is realized grinding at floor grinding machine aligning method.
Because adopt aforesaid scheme, the present invention has following superiority:
1, process the basic circle cambered surface at the bearing special purpose grinder, bus that can high-precision assurance basic circle cambered surface and the bus of outer ring periphery are parallel to each other, or say the preferably axiality that has of outer ring periphery and basic circle cambered surface.
2, the aligning method that the basic circle cambered surface that processes is introduced than background technology is simpler effectively, need not repeatedly to measure the Wall-Thickness Difference of outer ring raceway face and outer ring periphery, only need in the grinding process at any time that centering basic circle cambered surface gets final product, improved the grinding efficiency of outer ring on floor grinding machine.
3, after the grinding of outer ring raceway face is finished, the basic circle cambered surface that repairs again is that chamfering gets final product, and meets the designing requirement of outer ring.

Among Fig. 1: the 1-outer ring; The 2-pillar; The 3-chuck; The 4-cramp bar; The 5-pressing plate; The 6-magnetic power meter; The 7-grinding wheel spindle; A-basic circle cambered surface; B-outer ring raceway face; C-outer ring small end face; D-outer ring periphery; E-outer ring large end face.
The specific embodiment
For describing the present invention in detail, have the different end faces of outer ring 1 are self-defined: basic circle cambered surface A, outer ring raceway face B, outer ring small end face C, outer ring periphery D and outer ring large end face E, the relative outer ring of outer ring raceway face B 1 central axis has large cone angle, and described large cone angle makes outer ring 1 both ends of the surface produce outer ring large end face E and outer ring small end face C.
In conjunction with Fig. 1, be the steel-angle bearing of JM969241DW/NP311711 for model, the external diameter of its outer ring 1 be 650mm, width be the large cone angle of the relative outer ring of 90mm, outer ring raceway face B 1 central axis be 31 ° 30 ', the accuracy class of outer ring 1 is the P5 level, and the Wall-Thickness Difference that requires outer ring small end face C is 0.021mm.
The main purpose of aligning method of the present invention is to realize the grinding of outer ring raceway face B at floor grinding machine, secondly indirectly satisfies the required precision of outer ring small end face C Wall-Thickness Difference.For this reason, the aligning method that the present invention is directed to described main purpose comprises following content:
